Description

Rear sheet holding device

The present invention relates to an improved rear sheet holding device.

Some vehicles have seats that can be flipped up to increase the storage space in the passenger compartment. In such a vehicle, if the vehicle is run with the seat flipped up, a force may be applied in a direction in which the seat falls due to vibration or acceleration / deceleration. In such a case, a strap may be used to prevent the sheet from falling. By connecting a part of the passenger compartment and the seat through the strap, the seat can be prevented from falling down. Thereby, the state of the sheet being flipped up is maintained. There is a technique disclosed in Patent Document 1 regarding such a sheet holding device.

Patent Document 1 discloses a holding device for a rear sheet that can be flipped up toward a front sheet positioned on the side of a pillar. This holding device includes a strap whose base end is fixed to the lower portion of the pillar, and a fixing portion provided on the rear seat. The front end portion of the strap can be locked to the fixing portion of the rear seat that has been brought up. By locking the front end of the strap to the fixing portion, the rear seat is prevented from falling backward.

Here, when the holding device is not used, the tip of the strap is locked to the pillar. Moreover, the fixing | fixed part to which the front-end | tip part of a strap is latched is provided in the center of the side part of a rear seat. Therefore, it is necessary to engage and release the front end of the strap to the fixed portion in a narrow space between the side portion of the rear seat and the pillar. There is room for improvement in the workability of such a holding device.

JP-A-8-1113068

An object of the present invention is to provide a rear sheet holding device with high workability.

According to the present invention, in the rear seat holding device that holds the rear seat that can be flipped up toward the front seat located on the side of the pillar in the state of being flipped up,
A strap with a proximal end attached to the rear seat;
A locking part attached to the tip of this strap;
A fixing portion provided on the pillar so that the locking portion can be locked, and
The fixing portion is located near an upper portion of a through anchor provided in the pillar to hold the webbing belt for the front seat,
The locking portion is composed of a first piece portion to which a tip end portion of the strap is attached and a second piece portion detachable from the fixing portion,
The first piece portion is provided with a rear seat holding device that is inclined in a direction to avoid the through anchor when the second piece portion is locked to the fixed portion.

Preferably, the rear seat has a seat frame extending in the vehicle width direction, and protrusions are formed on the outer periphery of the seat frame at two different locations in the vehicle width direction, and the base end portion of the strap is It is located between the two protrusions.

In the present invention, the fixing portion that can be locked with the tip portion of the strap is located in the vicinity of the upper portion of the through anchor provided in the pillar in order to hold the webbing belt for the front seat.

¡Through anchor is provided at a site where no other parts exist so that the seated person can easily grasp the webbing belt. That is, the through anchor is generally provided in a wide space. In the present invention, a fixing portion is provided in the vicinity of the upper portion of such a through anchor. Since a large space can be used to engage and release the strap from the fixed portion, workability is improved. A rear sheet holding device with high workability can be provided.

Furthermore, in the present invention, a fixing portion is provided in the vicinity of the through anchor. The mounting strength of the through anchor on the pillar is high. For this reason, the attachment strength with respect to the pillar of a fixing | fixed part can also be raised. Thereby, it is possible to reliably prevent the rear seat in the flip-up state from falling over.

In addition, the locking portion attached to the tip of the strap includes a first piece to which the tip of the strap is attached and a second piece that is detachable from the fixing portion. When the two pieces are locked to the fixed portion, the two pieces are inclined toward the direction of avoiding the through anchor.

If there is no inclination, that is, if the first piece and the second piece are on one plane, the second piece is closer to the through anchor, and the end of the second piece is connected to the through anchor. There is a risk of interference. However, interference can be avoided if the second piece is inclined in a direction to avoid the through anchor. Thereby, it can prevent that a through anchor interferes with a latching | locking part and a strap, ensuring the high attachment strength of a fixing | fixed part.

Furthermore, if the fixing portion is provided apart from the through anchor, a plurality of belts or straps are stretched from locations separated from each other in the passenger compartment when the seat belt and the seat holding device are used, which is troublesome for the occupant. Make an impression. On the other hand, if the fixed portion is located in the vicinity of the through anchor as in the present invention, the base end portion of the belt or the like stretched in the vehicle interior is concentrated in one place, so that a complicated impression can be suppressed.

Furthermore, in the present invention, the rear seat has a seat frame extending in the vehicle width direction. On the outer periphery of the seat frame, projecting portions are formed at two different locations in the vehicle width direction, and the base end portion of the strap is located between the two projecting portions. When the locking portion is locked to the fixed portion, a force pulled in the pillar direction may be applied to the base end portion of the strap. Since the protrusion is formed on the outer periphery of the seat frame, the movement of the base end is restricted by the protrusion. Since the movement of the base end portion can be prevented, the rear seat in the flip-up state can be held more firmly.

The left and right latches 32b and 33b are integrally provided on a part of the left and right rear legs 34a and 34b.

A well-known mechanism is employed for the mechanism that causes the rear seat back 36 to lie down toward the rear seat cushion 35 and the mechanism that flips the rear seat 30 toward the front seat 20. In order to perform these operations, for example, an operation lever is provided on the side of the rear seat cushion 35 on the vehicle exterior side.

Refer also to FIG. A through anchor 14 for holding the webbing belt 13 for the front seat 20 is fixed to the upper portion of the center pillar 12.

In particular, as shown in FIG. 2, the rear seat 30 in the flipped-up state can stand on its own. However, when the vehicle is driven in the state of being flipped up, a force is applied backward due to vibration or acceleration / deceleration. A rear seat holding device 40 (hereinafter referred to as “holding device 40”) for preventing the rear seat 30 from falling backward is mounted on the vehicle body 10.

The holding device 40 is provided on the center pillar 12 so that the strap 50 attached to the rear seat 30, the locking portion 60 attached to the front end portion 51 of the strap 50, and the locking portion 60 can be locked. Fixing part 70.

The fixing part 70 is located near the upper part of the through anchor 14. The center of the fixing portion 70 is attached closer to the rear seat 30 than the center of the through anchor 14.

Next, attachment of the through anchor 14 and the fixing portion 70 to the center pillar 12 will be described in conjunction with FIG. The webbing belt 13 is a thing for restraining a passenger | crew. For this reason, the through anchor 14 for supporting the webbing belt 13 needs to be fixed to the center pillar 12 with high mounting strength.

The center pillar 12 includes a center pillar main body 12a formed of a steel plate and a center pillar garnish 12b formed of a resin that covers the center pillar main body 12a.

A hole through which the anchor bolt 16 of the through anchor 14 is inserted is formed in the center pillar main body 12a. On the back surface of the center pillar main body 12a, a thin-plate-like through anchor reinforcement member 15 is arranged in accordance with the shape of the back surface. The anchor bolt 16 attached to the through anchor 14 is inserted into the hole for the anchor bolt 16, and the through anchor 14 is attached to the center pillar body 12a. Of the center pillar 12, the rigidity of the portion where the through anchor reinforcing material 15 is disposed is increased. Therefore, the attachment strength of the through anchor 14 to the center pillar 12 is increased.

Similarly, a thin plate-shaped reinforcing member for fixing portion 71 is disposed on the back surface of the center pillar main body 12a, the fixing portion bolt 72 is inserted into the fixing portion bolt hole, and the through anchor 14 is attached to the center pillar main body 12a. . Therefore, the attachment strength of the fixed portion 70 to the center pillar 12 is also high. The fixing portion reinforcing material 71 can also be formed integrally with the through anchor reinforcing material 15.

FIG. 5 shows the rear seat cushion 35 of the rear seat 30 in the flipped-up state in a state of looking up obliquely upward from the floor (FIG. 1, reference numeral 11). For convenience of explanation, the skin and the cushion material are omitted.

A seat frame 81 is provided inside the rear seat cushion 35 so as to extend in the vehicle width direction. On the outer periphery of the seat frame 81, mounting portions 82 and 83 (protruding portions 82 and 83) for mounting the child seat on the rear seat 30 are formed. These mounting portions 82 and 83 are formed at two different locations in the vehicle width direction. The attachment portions 82 and 83 protrude from the outer periphery of the seat frame 81.

The base end portion 52 of the strap 50 is fixed by being wound around the seat frame 81 and is positioned between the attachment portions 82 and 83.

Next, the holding of the rear sheet 30 by the holding device 40 will be described.
As shown in FIG. 6, a locking portion 60 is attached to the distal end portion 51 of the strap 50 in which the base end portion 52 is wound around the seat frame 81 in the rear seat cushion 35. The rear seat 30 is supported by the center pillar 12 via the strap 50 by locking the locking portion 60 to the fixing portion 70. Even if the rear seat 30 in the flip-up state is about to fall backward, the rear seat 30 is supported by the strap 50, and the fall is prevented.

The fixing part 70 is located in the center pillar 12 near the upper part of the through anchor 14. Therefore, the holding device 40 has the following effects.

Usually, the through anchor 14 is provided at a site where no other parts exist so that the seated person can easily grasp the webbing belt 13. That is, the through anchor 14 is generally provided in a wide space. Also in this embodiment, there is a certain space between the front headrest 25 and the through anchor 14. For this reason, since the large space can be used to engage and release the strap 50 to the fixing portion 70, workability is improved.

In particular, in this embodiment, the center of the fixing portion 70 is attached closer to the rear seat 30 than the center of the through anchor 14. Therefore, the locking operation and the release operation can be performed by the occupant as compared with the case where the fixing portion 70 is attached to the front seat 20 side. Workability is further increased.

Furthermore, as described above, the through anchor 14 is provided on the back surface of the center pillar 12 with a reinforcing material for through anchor (FIG. 4, reference numeral 15), so that the mounting strength of the through anchor 14 to the center pillar 12 is increased. The attachment strength of the fixing portion 70 located in the vicinity of the through anchor 14 to the center pillar 12 can also be increased. It is possible to reliably prevent the rear seat 30 in the flipped-up state from falling over.

Furthermore, if the fixing portion 70 is provided apart from the through anchor 14, a plurality of webbings or straps 50 may be stretched from locations separated from each other in the vehicle compartment when the seat belt device and the rear seat holding device 40 are used. It gives a confusing impression to the crew. On the other hand, if the fixing portion 70 is positioned in the vicinity of the through anchor 14 as in the present invention, the base end portion of the webbing or the like stretched in the vehicle interior is concentrated in one place, so that a complicated impression can be suppressed.

Next, the detail of the latching | locking part 60 and the latching state of the latching | locking part 60 and the fixing | fixed part 70 are demonstrated.
As shown in FIG. 7A, the locking portion 60 includes a first piece portion 61 and a second piece portion 62 formed by bending a long plate.

Referring also to FIG. 7 (b), the first piece 61 has a long hole-shaped first hole 63. The strap 50 is passed through the first hole 63, and the locking portion 60 is attached to the strap 50. The second piece 62 is formed with a circular second hole 64 partially extending upward. In the locking part 60, the distal end of the fixing part 70 is inserted into the second hole 64 and the locking part 60 is slid downward, whereby the second piece part 62 is locked to the fixing part 70. At this time, the first piece 61 is inclined in a direction to avoid the through anchor 14.

If this inclination does not exist, that is, if the long plate is used as a locking portion as it is, the second piece 62 is closer to the through anchor 14 and the end of the second piece 62 is the through anchor 14. There is a risk of interference. However, interference can be avoided if the second piece 62 is inclined in a direction to avoid the through anchor 14. Thereby, it is possible to prevent the through anchor 14 from interfering with the locking portion 60 and the strap 50.

Note that the locking portion 60 does not avoid interference with the through anchor 14 only when the locking portion 60 is pulled backward by the strap 50. As shown in FIG. 8, even when only the locking portion 60 is attached to the fixing portion 70, the locking portion 60 and the through anchor 14 do not interfere with each other. That is, even when the distal end of the fixing portion 70 is inserted into the second hole 64 and the locking portion 60 slides downward, the locking portion 60 and the fixing portion 70 do not interfere with each other. When the holding device 40 is used, it is not necessary for the occupant to consider the interference between the fixing portion 70 and the locking portion 60, so that the locking and releasing operations are facilitated.

Further, as shown in FIG. 9, when the locking portion 60 is locked to the fixing portion 70, the rear seat 30 is supported by the strap 50 when the rear seat 30 falls back. Since the distal end portion 51 of the strap 50 is fixed to the center pillar 12, the proximal end portion 52 of the strap 50 is also pulled in the direction of the center pillar 12. However, attachment portions 82 and 83 for attaching the child seat to the rear seat 30 are formed on the outer periphery of the seat frame 81. Therefore, the base end portion 52 contacts the attachment portion 83. Since the movement of the base end portion 52 is restricted by the attachment portion 83, the movement of the base end portion 52 can be prevented. Therefore, it is possible to hold the rear sheet 30 in a state of being flipped up more firmly. At this time, the movement of the strap 50 can be restricted without increasing the number of parts.

The rear seat holding device of the present invention is suitable for mounting on a passenger car.
It is suitable for use in.
