  In the above seat device, since the cancel mechanism is provided at the center of the bottom surface of the seat cushion, a linkage wire for transmitting the movement of the seat back to the cancel mechanism is required between the seat back and the cancel mechanism. Furthermore, when the attachment position of the cancel mechanism is determined in this way, the link wire may be entangled with other members provided on the bottom surface of the seat cushion, so it is not preferable to provide the cancel mechanism at such a position.

  It is an object of the present invention to obtain a vehicle seat device in which the number of parts is reduced and a member for operating the cancel mechanism is prevented from contacting another member by devising the layout of the cancel mechanism. .

  A vehicle seat device according to the present invention includes a seat cushion, a side frame provided inside the seat cushion, and a seat back pivotally attached to the side frame so as to be relatively rotatable between a standing position and a folded position. And a front locking mechanism and a rear side, which are provided on the front and back of the bottom of the seat cushion, and are respectively engaged with and disengaged from a front striker and a rear striker projecting on a floor surface in a vehicle to lock or unlock the seat A lock mechanism, an operation device for releasing the lock of the front lock mechanism among the front and rear lock mechanisms, and an operation invalidating the lock release operation by the operation device when the seat back is in the upright position When the seat back is in the folded position, the operation for enabling the unlocking operation by the operating device is enabled. And a cancel mechanism that is in an effective state, wherein the cancel mechanism is attached to the side frame and engaged with the cancel mechanism when the seat back moves from the standing position to the folded position. A pressing portion for switching from the operation invalid state to the operation valid state is provided.

  For example, the cancel mechanism is pivotally attached to the side frame so as to be rotatable about a left-right axis, and is folded from an inoperative position when the seat back is in an upright position by a pressing portion of the seat back. A rotating piece that moves to the operating position when it is positioned, and a guide elongated hole and a switching hole that are formed in the rotating piece and the side frame, respectively, for guiding the same power transmission pin. The hole has an idle swinging portion that moves the power transmission pin to an interference position that interferes with the operation device and a non-interference position that does not interfere with, and a contactable portion that moves the power transmission pin at the interference position using the operation device. The guide elongated hole of the rotating piece has a shape overlapping with the contactable portion when the rotating piece is in the operating position, and the guide elongated hole of the rotating piece is in the non-operating position. Through the above power transmission The pin is held at the non-interference position of the idling part and the movement of the operating device is not transmitted to the front lock mechanism, and when it is in the operating position, the power transmission pin is brought into the interference position of the idling part via the guide slot. This can be realized by moving the contactable portion and the guide slot through the operation of the operation device and transmitting the movement to the front lock mechanism.

  For example, the operating device is linked to the front lock mechanism via a first operation wire, and rotates between a lock position where the front lock mechanism is locked and an unlock position where the front lock mechanism is unlocked. A possible lock operation member and a second operation wire are linked so as to rotate in conjunction with a lock release means provided on the seat back, and the power transmission pin is located in the contactable portion Sometimes when the unlocking means is operated, the power transmission pin is pressed while rotating, and the lock operation member is moved to the unlock position by the power transmission pin, and the power transmission pin is And a pin pressing member that rotates while swinging with respect to the power transmission pin when the lock release means is operated when positioned in the position. That.

  When the seat back is in the standing position, the rear locking mechanism is in the locked state, and when the seat back is in the folded position, the rear locking mechanism is in the unlocked state. In the case where an interlocking mechanism that interlocks the movements of the seat back and the rear locking mechanism is provided, it is preferable that the interlocking mechanism share a part of its constituent members with the canceling mechanism. In this way, the number of parts can be reduced.

  Thus, the interlock mechanism in the case of partially using the parts of the cancel mechanism and the interlock mechanism is, for example, when the seat back formed at the rotating piece and the seat back is in the upright position, When the seat back moves to the folding position without contacting the rotating piece, the pressing portion that contacts the rotating piece and rotates the rotating piece to the operating position; and When in the non-operating position, the hook that engages and disengages with the rear striker is moved to the lock position that engages with the rear striker, and when the rotating piece moves to the operating position, the hook is moved to the operating position. And a link member that moves to the unlock position for releasing the engagement with the rear striker.

  According to another aspect, the vehicle seat device of the present invention is configured such that a seat cushion, a side frame provided inside the seat cushion, and a relative rotation between the standing position and the folding position of the side frame are possible. A seat having a pivoted seat back and a front striker and a rear striker, which are provided on the front and back of the floor of the vehicle, and are respectively engaged with and disengaged from each other to lock or unlock the seat. A front locking mechanism and a rear locking mechanism; an operating device for unlocking the front locking mechanism and the rear locking mechanism; and when the seat back is in the upright position, the unlocking operation by the operating device is performed. When the operation is disabled and the seat back is in the folded position, the unlocking operation by the operating device is not performed. A cancel mechanism that is in an effective operation state, and the cancel mechanism is attached to the side frame, and when the seat back is moved from the standing position to the folding position, the cancel mechanism is It is characterized by comprising a pressing part that engages and switches from the operation invalid state to the operation valid state.

  For example, the cancel mechanism is pivotally attached to the side frame so as to be rotatable about a left-right axis, and is folded from an inoperative position when the seat back is in an upright position by a pressing portion of the seat back. A rotating piece that moves to the operating position when it is positioned, and a guide elongated hole and a switching hole that are formed in the rotating piece and the side frame, respectively, for guiding the same power transmission pin. The hole has an idle swinging portion that moves the power transmission pin to an interference position that interferes with the operation device and a non-interference position that does not interfere with, and a contactable portion that moves the power transmission pin at the interference position using the operation device. The guide elongated hole of the rotating piece has a shape overlapping with the contactable portion when the rotating piece is in the operating position, and the guide elongated hole when the rotating piece is in the non-operating position. Through the above power transmission The pin is held at the non-interference position of the idle swinging portion so that the movement of the operating device is not transmitted to the front locking mechanism and the rear locking mechanism, and when in the operating position, the power transmission pin is swung through the guide slot. It can be realized by moving the contactable portion and the guide slot through the operation device and transmitting the information to the front lock mechanism and the rear lock mechanism.

  For example, the operating device is linked to the front lock mechanism via a first operation wire, and rotates between a lock position where the front lock mechanism is locked and an unlock position where the front lock mechanism is unlocked. A possible lock operation member and a second operation wire are linked so as to rotate in conjunction with a lock release means provided on the seat back, and the power transmission pin is located in the contactable portion Sometimes when the unlocking means is operated, the power transmission pin is pressed while rotating, and the lock operation member is moved to the unlock position by the power transmission pin, and the power transmission pin is When the unlocking means is operated when positioned at the position, the pin pressing member that rotates while swinging with respect to the power transmission pin, and the lock operating member are At the same time move to the click position, it is possible to adopt a configuration comprising, as above power transmission pin for switching the unlocked state the rear locking mechanism from the locked state. When the operating device has such a configuration, the operating device and the cancel mechanism share the power transmission pin, so that the number of parts can be reduced.

  The rear lock mechanism can be rotated between a lock position that can be engaged with the rear striker and an unlock position that releases the engagement, and is always urged to rotate toward the unlock position. And can be rotated between an engagement position that engages with the hook and holds the hook in the locked position, and an engagement release position that releases the engagement with the hook. When the lock release means is operated when the power transmission pin is held in the contactable portion and held in the engagement position, the power transmission pin is rotated toward the engagement release position by the power transmission pin; It is possible to make it the structure provided with.

  According to the present invention, by devising the layout of the cancel mechanism, the number of parts of the vehicle seat device is reduced, and contact between the member for operating the cancel mechanism and other members is prevented.

The rear end portion of the rod 72 is pivotally attached to the middle portion of the right rotation arm 60 so as to be rotatable about a left-right axis. Since the rod 72 of the gas spring 70 is always urged in a direction protruding from the cylinder 71, the opening angle of the seat cushion 20 and the rotating arm 60 is in the state shown in FIGS. 2 and 4 in a free state. is there.

  The retractable vehicular seat apparatus SA having the above-described configuration is fixed to the front surface 13a of the retractable recess 13 by a bolt B (see FIG. 6), thereby fixing the connecting member 63 to the floor surface 11 of the vehicle 10. The seat use position (the solid line in FIG. 1 and the position in FIG. 2) mounted on the sheet installation surface 12 and the storage position in the storage recess 13 (the position of the imaginary line in FIG. And the position of FIG. 3).

Next, the operation of the retractable vehicle seat apparatus SA configured as described above will be described.
First, an operation of moving the sheet S at a position away from the sheet use position and the storage position to the storage position and holding it at the storage position will be described.
In this case, first, the seat back 21 of the seat S is moved to the folding position, and the turning arm 60 is moved while narrowing the opening angle of the seat cushion 20 and the turning arm 60 against the urging force of the gas spring 70. By rotating backward, the sheet S is moved to the rear rotational end. Then, the seat S is positioned at the storage position where the entire sheet S is positioned in the storage recess 13 and the lower surface of the seat cushion 20 is in contact with the bottom surface of the storage recess 13 (see the phantom line in FIG. 1 and FIG. 3). ). When the seat back 21 is moved to the folding position in this way, the pressing portion 21a formed at the lower end of the seat back frame presses the projection A3 of the operation piece A, and rotates the operation piece A in the counterclockwise direction. Therefore, the contact portion A2 presses the pressed pin 40 downward, and the rotating piece 36 in the inoperative position rotates in the clockwise direction in FIGS. Then, as shown in FIGS. 8 and 9, the power transmission pin 41 located at the non-interference position fitted to the front end portion of the guide elongated hole 36 a and the upper end portions of the idle swing portions 28 c 1 and 30 c 1 of the switching holes 28 c and 30 c. However, while maintaining the fitting relationship with the guide elongated hole 36a, the front end of the contactable portions 28c2 and 30c2 is moved downward in the idle swing portions 28c1 and 30c1 and the rotating piece 36 reaches the operating position. And it is located in the interference position fitted in the engaging groove 43a of the pin pressing member 43. Although illustration is omitted, at this time, the guide elongated hole 36a and the contactable portions 28c2, 30c2 are overlapped in the left-right direction. When the power release pin 41 is moved to the interference position in this way and the lock release switch is manually moved to the lock release position, the front lock control wire W1 is pulled, so that the pin pressing member 43 is engaged. While pulling the power transmission pin 41 fitted in the groove 43a, it rotates counterclockwise in FIG. 8 and moves the power transmission pin 41 rearward along the guide long hole 36a and the contactable portions 28c2 and 30c2. . Then, the power transmission pin 41 is fitted into the engagement recess 44a of the hook operation member 44, and the hook operation member 44 in the lock position shown in FIG. 8 is rotated counterclockwise to the unlock position (not shown). The unlocking wire W2 is pulled backward. As a result, the pawl 56 of the front lock mechanism U2 rotates clockwise and disengages from the hook 55, so that the hook 55 moves to the unlock position by the urging force of the torsion spring 57.

The state of the cancellation mechanism when the power transmission pin 41 is located at the non-interference position is referred to as an operation invalid state, and the state of the cancellation mechanism when the power transmission pin 41 is located within the interference position and the contactable portions 28c2 and 30c2. Is called the operation enabled state.
When the lock release switch is moved to the unlock position when the cancel mechanism is in the operation valid state as described above, the pin pressing member 43 moves the power transmission pin 41. However, even if the lock release switch is moved to the lock release position when the cancel mechanism is in the operation invalid state, the pin pressing member 43 is swung with respect to the power transmission pin 41, so that the hook operation member 44 and the lock release wire W2 are moved. The pole 56 and the hook 55 do not move.

  When the lock release switch is returned to the lock effective position and the pole 56 is returned to the original position by the urging force of the torsion spring 58 and the seat S is moved to the storage position, the storage position is maintained as shown in FIGS. The striker 64 enters the end portion side of the striker entry groove 52 and engages with the engagement groove 55a of the hook 55 to rotate the hook 55 counterclockwise. The hook 55 continues to rotate counterclockwise while the engaging portion 55c is in sliding contact with the outer peripheral surface of the pole 56. When the hook 55 reaches the lock position shown in FIG. 56a is engaged and held in the locked position. When the hook 55 is held in the locked position in this way, the arm portion 55b of the hook 55 is engaged with the storage position holding striker 64 and closes the open end of the striker entry groove 52, so that the sheet S is stored. Unmovable from position.

Next, an operation of moving the sheet S from the storage position to the sheet use position and holding it at the sheet use position will be described.
In this case, first, the lock release switch is operated to the lock release position side, the front lock control wire W1 and the lock release wire W2 are pulled, the pole 56 is rotated clockwise, and then the lock release switch is moved to the lock effective position. Return to. Once the pawl 56 rotates clockwise, the engagement between the engaged portion 56a and the engaging portion 55c is released, so that the hook 55 rotates toward the unlocked position by the urging force of the torsion spring 57. For this reason, when the seat S is rotated forward, the storage position holding striker 64 escapes from the striker entry groove 52.

After the storage position holding striker 64 has escaped from the striker entry groove 52, the seat S is further rotated forward while the seat back 21 is held in the folded position, and moved to the seat use position as it is.
When the sheet S reaches the seat use position, first, the rear striker 14 is caused to enter the striker entry grooves 28a and 30a of the rear lock mechanism U1, and is brought into contact with the end portions of the striker entry grooves 28a and 30a. Next, the seat cushion 20 is rotated forward around the contact point between the rear striker 14 and the striker entry grooves 28a and 30a, and the front striker 15 is caused to enter the striker entry groove 52 of the front lock mechanism U2. Then, the front striker 15 is engaged with the engagement groove 55a of the hook 55, and the hook 55 is rotated counterclockwise to the lock position against the urging force of the torsion spring 57. When the hook 55 reaches the locked position, the engaging portion 55 c of the hook 55 and the engaged portion 56 a of the pole 56 are engaged, and the front striker 15 is prevented from coming off from the striker entry groove 52 by the hook 55.

Thereafter, when the seat back 21 is moved to the standing position, the pressing portion 21a is separated from the operation piece A, so that the rotating piece 36 in the operating position is rotated counterclockwise to the non-operating position by the urging force of the torsion spring 39. Then, the hook 32 moves to the lock position, the engagement groove 32a of the hook 32 engages with the rear striker 14 entering the striker entry grooves 28a and 30a, and the rear striker 14 is engaged by the arm portion 32b. It is prevented from coming off from the striker entry grooves 28a, 30a.
In this way, when the front and rear strikers 14 and 15 and the front and rear locking mechanisms U1 and U2 are locked, the sheet S is held at the seat use position (see the solid line in FIG. 1 and FIG. 2).

  In order to return the seat S from the seat use position to the retracted position, first, the seat back 21 is moved to the folding position, the hook 32 of the rear lock mechanism U1 is moved to the unlock position, and the rear striker 14 is moved. Is made to be able to escape from the striker entry grooves 28a, 30a. Next, the lock release switch is operated to rotate the hook 55 toward the unlocked position by the urging force of the torsion spring 57, so that the front striker 15 can be removed from the striker entry groove 52. Thereafter, if the seat S is rotated rearward, the rear striker 14 and the front striker 15 escape from the striker entry grooves 28a and 30a and the striker entry groove 52, respectively, so that the sheet S is returned to the storage position. be able to.

According to the present embodiment, since the cancel mechanism is attached to the side frame 23 of the seat cushion 20, a connecting wire for interlocking the cancel mechanism and the seat back becomes unnecessary, and the number of parts is reduced as compared with the related art. be able to. Further, there is no possibility that the linking wire comes into contact with other components provided on the bottom surface of the seat cushion 20.
Further, since the rotating piece 36 is used as a common member for the cancel mechanism and the interlock mechanism, the cancel mechanism and the interlock mechanism are effectively integrated, so that the cancel mechanism and the interlock mechanism are completely separated. Compared to the number of parts, the manufacturing cost can be reduced.

  Further, before the retractable vehicle seat device SA is attached to the floor surface 11 of the vehicle 10, the position of the retractable vehicle seat device SA is adjusted in advance so that the front lock mechanism U2 can be engaged with the retractable vehicle seat device SA. Therefore, the position adjustment of the storage position holding striker 64 is completed in the manufacturing process of the retractable vehicle seat apparatus SA. Therefore, it is easier to attach the retractable vehicle seat device SA to the floor 11 of the vehicle 10 than in the past.

  In addition, the front lock mechanism U2 has a function of engaging and disengaging both the front striker 15 for holding the sheet S in the sheet use position and the storage position holding striker 64 for holding the sheet S in the storage position. As a result, the number of parts can be reduced compared to the case where the seat S is provided with two lock mechanisms that engage with and disengage from the strikers 15 and 54, respectively. As a result, the manufacturing cost can be reduced. it can.

Next, a second embodiment of the present invention will be described with reference mainly to FIGS. The same members as those in the first embodiment are designated by the same reference numerals, and detailed description thereof is omitted.
In this embodiment, the structure of the rear lock mechanism is changed, and the movement of the seat back 21 to the folding position and the movement of the hook 32 to the unlock position are not linked, similarly to the front lock mechanism U2. After the seat back 21 is moved to the folding position, the unlock switch is moved to the unlock position by moving the lock release switch to the unlock position.

This rear side lock mechanism U3 removes the link member 34 from the rear side lock mechanism U1 of the first embodiment, and instead, around the rotary shaft 80 installed between the base member 28 and the outer frame 30, FIG. The pole 81 which can rotate between the engagement position shown in FIG. 15 and the engagement release position shown in FIG. The pole 81 has an arm portion 81a, and is constantly urged to rotate counterclockwise in FIGS. 14 and 15 by an urging force of a torsion spring (not shown). Further, the hook 82 of the rear lock mechanism U3 includes an engaging portion 82c that can be engaged with and disengaged from the engaged portion 81b of the pole 81 in addition to the engaging groove 82a and the arm portion 82b. By the omitted torsion spring, it is always urged to rotate clockwise in FIGS. 14 and 15.
As shown in FIG. 14, when the seat back 21 is in the upright position, the engaged portion 81b of the pole 81 and the engaging portion 82c of the hook 82 are engaged, and the arm portion 81a of the pole 81 is seen in a side view. It overlaps with the contactable portions 28c2 and 30c2 of the switching holes 28c and 30c.
Since the structure and operation of the outer frame 30 and the members (pin pressing member 43, hook operation member 44) provided on the outer frame 30 are the same as those in the first embodiment, the figure corresponding to FIG. 8 is omitted. Yes.
The operation device according to the present embodiment includes a lock release switch, a front lock control wire W1, a lock release wire W2, a power transmission pin 41, a pin pressing member 43, and a hook operation member 44.

Next, the operation of the retractable vehicle seat apparatus SA having the above-described configuration will be described focusing on the movement of the rear lock mechanism U3.
First, a case where the sheet S at a position away from the sheet use position and the storage position is moved to the storage position and held at the storage position will be described.
In this case, as in the first embodiment, as shown in FIG. 15, the seat back 21 of the seat S is moved to the folding position, and the opening angle of the seat cushion 20 and the rotating arm 60 is narrowed. The moving arm 60 is rotated backward to place the sheet S in the retracted position. When the seat back 21 is moved to the folding position in this manner, as in the first embodiment, the front end portion of the guide long hole 36a and the upper end portions of the idle swing portions 28c1 and 30c1 of the switching holes 28c and 30c are not fitted. The power transmission pin 41 located at the interference position moves downward in the idle swing portions 28c1 and 30c1 while maintaining the fitting relationship with the guide elongated hole 36a, and the front end portions of the contactable portions 28c2 and 30c2. It moves to the interference position that fits into the engaging groove 43a of the pin pressing member 43. When the unlock switch is manually moved to the unlock position in this state, the front lock control wire W1 is pulled, so that the pin pressing member 43 connects the power transmission pin 41 to the guide long hole 36a and the contactable portion 28c2. Move backward along 30c2. At this time, as shown in FIG. 15, since the power transmission pin 41 presses the arm portion 81a of the pole 81 backward, the pole 81 rotates clockwise to the disengagement position, and the engaged portion 81b of the pole 81 And the engaging portion 82c of the hook 82 are disengaged.

Further, when the power transmission pin 41 moves rearward in this way, the engagement between the pole 56 and the hook 55 of the front lock mechanism U2 is released as in the first embodiment, so that the hook 55 is brought into the unlock position. The hook 55 and the front striker 15 are disengaged.
When the lock release switch is returned to the lock effective position (the pole 56 is returned to the original position) and the seat S is moved to the storage position, the storage position holding striker 64 enters the striker entry groove 52 of the front lock mechanism U2. The hook 55 engages with the engagement groove 55a of the hook 55, and the hook 55 rotates counterclockwise. Then, the storage position holding striker 64 moves to the end portion side of the striker entry groove 52, and when the hook 55 reaches the lock position, its engaging portion 55c engages with the engaged portion 56a of the pole 56. Since the sheet S is held at the lock position, the sheet S cannot be moved from the storage position.

  In order to move the sheet S from this state to the sheet use position, first, the lock release switch is moved to the lock release position. Then, as in the first embodiment, the pole 56 rotates in the clockwise direction, and the engagement between the engaged portion 56a and the engaging portion 55c is released, so that the hook 55 is unloaded by the urging force of the torsion spring 57. Rotate towards the locked position. When the lock release switch is returned to the lock effective position and the seat S is rotated forward, the storage position holding striker 64 escapes from the striker entry groove 52. When the lock release switch is returned to the lock effective position in this way, the pole 56 returns to the original position and the power transmission pin 41 returns to the interference position, so that the pole 81 is moved to the engagement position by the urging force of the torsion spring. Return.

  Since both the hooks 82 and 55 of the rear lock mechanism U3 and the front lock mechanism U2 are in the unlock position, the seat S is moved to the seat use position while the seat back 21 is held in the folded position. Is made to enter the striker entry grooves 28a, 30a of the rear side lock mechanism U3. Then, the rear striker 14 is engaged with the engagement groove 82a of the hook 82, and the hook 82 is rotated counterclockwise to the lock position. When the hook 82 reaches the locked position, the engaging portion 82c is engaged with the engaged portion 81b of the pole 81, the hook 82 is held in the locked position, and the rear striker 14 is moved from the striker entry grooves 28a, 30a. It is prevented from coming off.

Thereafter, when the seat cushion 20 is further rotated forward about the contact point between the hook 82 and the rear striker 14 and the front striker 15 enters the striker entry groove 52, the front striker 15 engages with the hook 55. Engage with the groove 55a and rotate the hook 55 counterclockwise to the locked position. Then, the engaging portion 55 c of the hook 55 engages with the engaged portion 56 a of the pole 56, and the hook 55 is held in the locked position, so that the front striker 15 is prevented from coming off from the striker entry groove 52.
In this way, the hooks 55 and 82 of the front and rear lock mechanisms U2 and U3 are locked to the front and rear strikers 14 and 15, whereby the sheet S is held in the sheet use position.

  When the seat back 21 is moved to the upright position after the power transmission pin 41 has moved to the interference position as described above, the pressing portion 21a is separated from the operation piece A, so that the rotating piece 36 is attached to the torsion spring 39. The power transmission pin 41 is moved to the upper end of the idle swing portions 28c1 and 30c1 of the switching holes 28c and 30c by rotating counterclockwise by the force.

  In order to return the seat S from the seat use position to the retracted position, after the seat back 21 is moved to the folding position, the lock release switch is moved to the lock release position, and the front lock mechanism U2 and the rear lock mechanism are moved. The engagement between the poles 56 and 81 of U3 and the hooks 55 and 82 is released. In this state, when the seat S is lifted obliquely rearward, the hook 82 rotates clockwise against the urging force of the torsion spring, and the engagement groove 82a of the hook 82 and the striker entry grooves 28a, 30a are directed in the same direction. The rear striker 14 comes out of the striker entry grooves 28a, 30a, and the front striker 15 comes out of the striker entry groove 52 while rotating the hook 55 to the unlock position side. It can be returned to the storage position.

Also in this embodiment, since the cancel mechanism is attached to the side frame 23 of the seat cushion 20, a linking wire for interlocking the cancel mechanism and the seat back 21 is not necessary.
Furthermore, since the operating device and the cancel mechanism share the power transmission pin 41, the number of parts can be reduced.

In the first and second embodiments, the movement of the pressing portion 21 a provided on the seat back 21 is transmitted to the pressed pin 40 of the rotating piece 36 via the operation piece A provided on the side frame 23.
