Description
Technical Field
The present invention relates generally to a seat assembly for a vehicle. More particularly, the present invention relates to a seat assembly that is selectively movable between a design position, an reclined position, and a folded position.
Background
The subject matter discussed in the background section should not be considered to be prior art merely because of its mention in the background section. Similarly, the problems mentioned in the background section are related to the subject matter of the background section and should not be assumed to have been previously recognized in the prior art. The subject matter in the background section is merely representative of various approaches that may themselves correspond to implementations of the claimed technology.
Motor vehicles typically include a seat assembly having a seat cushion and a seat back for providing a comfortable seating surface for an occupant. In sedan-type vehicles, compact Sport Utility Vehicles (SUVs), or other vehicles, the rear seat assembly is typically secured to the floor of the vehicle and the seat adjustability is limited due to limited space within the cargo compartment that interfaces with the cabin of such vehicles.
It is known to include a recliner assembly operatively coupled between a seat back and a seat cushion. Such recliner assemblies allow pivotal adjustment of the seat back between a use position and a reclined rearward position to provide comfort to the occupant of the seat. However, such recliner assemblies employ complex mechanisms that increase cost and space requirements. Furthermore, the use of such recliner assemblies generally requires more packaging space between adjacent seats and reduces the amount of storage space available behind the seat assembly. Such recliner assemblies allow for simultaneous movement of the seat cushion and seat back and often require complex mechanisms.
It is therefore desirable to provide a seat assembly that is selectively movable between a design seat position, a reclined position, and a folded position while maximizing passenger comfort and cabin storage space.

The present invention relates to a seat assembly for a vehicle. The seat assembly is selectively movable between a design position, a reclined position, and a folded position and maximizes occupant comfort and storage or cargo space of the cabin of the vehicle. The seat assembly can be easily removed from the vehicle to maximize cargo space.
Fig. 1 illustrates a perspective view of a seat assembly 100 for a vehicle in accordance with an embodiment of the present invention. The seat assembly 100 includes a seat cushion 102 mounted to a fixed cushion frame 104 of the vehicle, and a back frame 106 coupled to the seat cushion 102 by a linkage 108. The back frame 106 is coupled with the seat cushion 102 in such a manner that movement of the seat cushion 102 relative to the seat cushion frame 104 causes the back frame 106 to simultaneously rotate to improve the comfort of a person sitting on the seat cushion 102. The seat assembly 100 also includes a back frame locking mechanism 110 that cooperates with the linkage mechanism 108 to allow the back frame 106 to fold over the seat cushion 102 to maximize the storage or cargo space of the cabin of the vehicle.
According to an embodiment of the present invention, the seat cushion 102 may be equipped with a slide and lock mechanism 112 (best shown in fig. 4) to control movement of the seat cushion 102 relative to the cushion frame 104. The slide and lock mechanism 112 may allow the seat cushion 102 to be positioned between the retracted position and the extended position.
According to an embodiment of the present invention, when the lever of the back frame locking mechanism 110 is in the engaged position, the back frame locking mechanism 110 controls rotation of the back frame 106 relative to the back frame rotation axis X1.
In accordance with an embodiment of the present invention, the back frame locking mechanism 110 may control the rotation of the back frame 106 onto the seat cushion 102. The back frame locking mechanism 110 may also facilitate an efficient transition between the design position and the reclined position of the seat assembly 100.
Fig. 2A-2C illustrate various positions of the seat assembly 100. The seat assembly 100 is selectively movable between a design position, an reclined position, and a folded position. As shown in fig. 2A, in the design position, the seat cushion 102 and the back frame 106 are in the retracted position. The retracted position of the seat cushion 102 corresponds to the rearmost position of the seat cushion 102, i.e., without any forward movement. The retracted position of the back frame 106 corresponds to a position of the back frame 106 at a predetermined retraction angle a from the vertical axis. In one embodiment, the predetermined retraction angle a may have a value in the range from 21 ° to 25 ° in the design position of the seat assembly 100.
As shown in fig. 2B, in the reclined position, the seat cushion 102 and the back frame 106 are in the extended position. The extended position of the seat cushion 102 corresponds to a forward position of the seat cushion 102 that is achieved using the slide and lock mechanism 112. The slide and lock mechanism 112 allows the seat cushion 102 to move forward a predetermined distance relative to the cushion frame 104. In one embodiment, the slide and lock mechanism 112 may allow the seat cushion 102 to move forward in a range of 0 to 40mm relative to the cushion frame 104. The extended position of the back frame 106 corresponds to a position of the back frame 106 at a predetermined extension angle B from the vertical axis. In one embodiment, the predefined extension angle B may be in the range from 32 ° to 36 ° in the reclined position of the seat assembly 100. The transition between the design position and the reclined position of the seat assembly 100 increases the comfort of an occupant seated on the seat cushion 102.
During the transition between the design position and the reclined position of the seat assembly 100, the back frame locking mechanism 110 may lock movement of the back frame 106 such that the back frame 106 rotates about the back frame rotational axis X1 to provide a comfortable seating position for the occupant. The back frame locking mechanism 110 may lock movement of the back frame 106 about an axis X3 (as best shown in fig. 1) through a top portion of the back frame 106. Further, during this transition, the slide and lock mechanism 112 enables movement of the seat cushion 102, which in turn enables simultaneous rotation of the back frame 106 about the back frame axis of rotation X1 to provide a desired comfort position for the occupant while occupying the seat assembly 100.
As shown in fig. 2C, in the folded position, the back frame 106 may be fully folded over the seat cushion 102 to maximize the space of the cabin of the vehicle. The back frame 106 may be folded onto the seat cushion 102 using the back frame locking mechanism 110. In one embodiment, the back frame locking mechanism 110 prevents the back frame 106 from rotating relative to the back frame rotation axis X1 when the lever (shown in fig. 6) of the back frame locking mechanism 110 is in the engaged position. Further, the back frame locking mechanism 110 allows rotation of the back frame 106 relative to the back frame axis of rotation X1 when the lever is in the disengaged position. The folded position of the seat assembly 100 corresponds to the position where the back frame 106 covers the seat cushion 102 such that the storage or cargo space of the cabin is increased.
According to embodiments of the present invention, the back frame locking mechanism 110 may enable rotation of the back frame 106 relative to the back frame axis of rotation X1 when the seat assembly 100 is in the design position, and may prevent rotation of the back frame 106 relative to the back frame axis of rotation X1 when the seat assembly 100 is in the reclined position.
Fig. 3 illustrates an exploded view of the seat assembly 100 according to an embodiment of the present invention. The linkage mechanism 108 for coupling the seat cushion 102 with the back frame 106 may include an inner side link 302 and an outer side link 304, each disposed at a lateral end portion of the seat cushion 102 and connecting the lateral end portion of the seat cushion 102 with the back frame 106. The inner side link 302 and the outer side link 304 may be angled links, such as L-shaped links. In one embodiment, the inner 302 and outer 304 side links may be elbow-forming angle links, the angle of which may vary depending on their design requirements.
According to an embodiment of the invention, the lower ends of the inner and outer side links 302, 304 may be fastened to the lateral ends of the seat cushion 102. In one embodiment, the lower ends of the inner and outer side links 302, 304 may be fastened to the lateral ends of the seat cushion 102 using rivet and bushing arrangements 306. In addition, a stopper 308 may be provided at a fastening position of the lower ends of the inner and outer links 302 and 304 to limit rotation of the inner and outer links 302 and 304 to a predetermined degree with respect to an axis X2 (as clearly shown in fig. 1) corresponding to the lower ends of the inner and outer links 302 and 304.
According to an embodiment of the invention, the upper ends of the inner and outer side links 302, 304 may be fastened to the lateral ends of the back frame 106. In one embodiment, the upper ends of the inner and outer side links 302, 304 may be fastened to the lateral ends of the back frame 106 using screw and bolt arrangements 310. This configuration allows the back frame 106 to rotate about a back frame rotation axis X1 that corresponds to a line connecting lateral ends of the back frame 106 at a position where upper ends of the inner and outer side links 302, 304 are fastened.
Fig. 4 illustrates a schematic view of the slide and lock mechanism 112 of the seat assembly 100 in accordance with an embodiment of the present invention. The slide and lock mechanism 112 controls movement of the seat cushion 102 relative to the cushion frame 104 between the retracted position and the extended position. The retracted position of the seat cushion 102 may correspond to the positioning of the seat cushion 102 in the design position of the seat assembly 100, i.e., when the seat cushion 102 is positioned on the cushion frame 104 of the vehicle without any forward movement. The extended position of the seat cushion 102 may correspond to the positioning of the seat cushion 102 in the reclined position of the seat assembly 100, i.e., when the seat cushion 102 is positioned on the cushion frame 104 with a predetermined forward movement. In an embodiment, the slide and lock mechanism 112 may enable a predetermined forward movement of the seat cushion 102 in the range of 0 to 40 mm.
According to an embodiment of the invention, the slide and lock mechanism 112 may include a lever 402 coupled with a link 404, the link 404 being secured to the bottom surface of the seat cushion 102. Actuation of the lever 402 may enable the seat cushion 102 to move forward relative to the cushion frame 104 of the vehicle. In an embodiment, the lever 402 may be designed in such a way that upward movement of the lever 402 enables forward movement of the seat cushion 102. Additionally, tabs 406 may be provided on both sides of the lever 402 to prevent lateral movement of the lever 402. Further, a restricting member 408 may be provided to restrict upward movement of the lever 402. The lever 402 may be adapted to move in 10mm increments to effect forward movement of the seat cushion 102 relative to the cushion frame 104 of the vehicle. The lever 402 may be a component configured to provide leverage for pulling the seat cushion 102, such as a metal lever, a pull strap, or the like.
The slide and lock mechanism 112 may also include a lock guide 410, the lock guide 410 being configured to couple with a slot provided on the cushion frame 104. The seat cushion 102 may include a plurality of slots 412 on a bottom surface thereof adapted to engage the locking guides 410 to enable the seat cushion 102 to move relative to the cushion frame 104 when the lever 402 is moved upward and pulled forward. The locking guides 410 that engage with the plurality of slots 412 of the seat cushion 102 may be coupled with the slots of the cushion frame 104 in such a way that movement of the seat cushion 102 is limited to a predetermined range, such as 0 to 40mm. The locking guide 410 may be formed of plastic, metal, or alloy.
Fig. 5 shows an exploded view of the seat cushion 102. As shown, the lever 402 of the slide and lock mechanism 112 may include a plurality of slots 502 for engaging a set of protrusions provided on the seat cushion frame 104. The lever 402 may be secured to the seat cushion 102 using any fastening technique, such as bolting, riveting, or the like. Further, the at least two slits 502 of the lever 402 may correspond to the retracted and extended positions of the seat cushion 102, respectively, and enable locking of the seat cushion 102 in the retracted and extended positions to enable transition between the design and reclined positions of the seat assembly 100.
According to an embodiment of the invention, each of the plurality of slits 502 may correspond to a predetermined position of the seat cushion 102 such that locking of a particular slit 502 may allow an occupant to shift the seat cushion 102 to a corresponding position relative to the cushion frame 104. In one embodiment, each of the plurality of slits 502 is spaced apart from an adjacent slit by 10mm. It should be appreciated that this design of the slot 502 may be scalable or modular to allow for discontinuous cushion movement, such as movement at 10mm intervals. While the seat assembly 100 and its components are simple and economical to operate in principle, they can likewise be scaled to achieve a recline function on a multi-position latch.
According to an embodiment of the invention, the seat cushion 102 may be provided with an attachment bracket 504, the attachment bracket 504 being coupled to a rear portion of the seat cushion 102 to allow the lower ends of the inner and outer side links 302, 304 of the linkage mechanism 108 to be fastened to the seat cushion 102. The seat cushion 102 may also be provided with a torsion bar assembly 506, the torsion bar assembly 506 connecting the lateral ends of the attachment brackets 504 to prevent over-rotation of the inner and outer side links 302, 304 about an axis X2 passing through the lower ends thereof, while maintaining proper tension in the linkage 108. This configuration allows rotation of the back frame 106 about the back frame rotation axis X1 while preventing rotation of the back frame 106 about the axis X2, the axis X2 passing through the lower ends of the inner and outer side links 302, 304 fastened to the attachment bracket 504.
In accordance with an embodiment of the present invention, the seat cushion 102 and the back frame 106 may be provided with a plurality of cushion wire arrangements 508 to support cushioning material provided to cover the seat assembly 100.
Fig. 6 illustrates a perspective view of the back frame locking mechanism 110 of the seat assembly 100 in accordance with an embodiment of the present invention. The back frame locking mechanism 110 includes a striker 602 mounted to a top portion of the back frame 106. The ram 602 may include a latch assembly 604 (also referred to hereinafter as a "high latch") actuated by a lever 606. The high latch 604 may be coupled with a striker wire assembly 608 that is fixed with the cabin of the vehicle or the vehicle environment to prevent movement of the top portion of the back frame 106 during the transition between the design position and the reclined position of the seat assembly 100. During such transition, the back frame locking mechanism 110 locks movement of the back frame 106 about an axis X3 corresponding to the longitudinal axis of the back frame 106 at the location where the high latch 604 is coupled with the striker wire assembly 608. The ram wire assembly 608 can include a wire adapted to couple or decouple the high latch 604 of the ram 602. The striker wire assembly 608 may have a plate including a plurality of slots adapted to be secured to a cabin of a vehicle.
According to an embodiment of the invention, during the transition of the seat assembly 100 from the design position to the folded position, the lever 606 of the striker 602 may be actuated to disengage the latch assembly 604 from the striker wire assembly 608, allowing the top portion of the back frame 106 to move to enable the back frame 106 to fully rotate about the back frame axis of rotation X1. The lever 606 of the striker 602 may be actuated to enable the back frame 106 to be rotated onto the seat cushion 102 to selectively transition from the design position to the folded position of the seat assembly 100.
Fig. 7A-7C illustrate perspective views of a seat assembly configured to be removed from a vehicle in accordance with an embodiment of the present invention. To maximize cargo space in the cabin of the vehicle, the seat assembly 100 may be removed or detached from the fixed cushion frame 104 of the vehicle. As shown in fig. 7A, to detach the seat assembly 100 from the seat cushion frame 104, the lever 402 may be moved upward to enable the seat cushion 102 to move forward relative to the seat cushion frame 104. The seat cushion 102 may then be moved forward, either completely or entirely, and the high latch 604 may then be released. To release the high latch 604, as shown in fig. 6, the lever 606 of the striker 602 may be actuated to disengage the high latch 604 from the striker wire assembly 608 to allow the top portion of the back frame 106 to move and enable the back frame 106 to fully rotate about the back frame axis of rotation X1 to transition the seat assembly 100 to the folded position. Thereafter, the seat assembly 100 may be moved forward, either completely or entirely, relative to the seat cushion frame 104 until the plurality of slots 412 on the bottom surface of the seat cushion 102 are disengaged from the locking guides 410. In one embodiment, when the locking guide 410 engaged with the plurality of slots 412 of the seat cushion 102 is coupled with the slots of the cushion frame 104 to limit movement of the seat cushion 102 from 0 to 40mm, the seat assembly 100 may be moved 40mm in a forward direction relative to the cushion frame 104 to remove it from the cushion frame 104.
As shown in fig. 7B and 7C, each of the plurality of slots 412 located on the bottom surface of the seat cushion 102 may include an open space 702, the open space 702 being sized larger than the corresponding locking guide 410. During removal of the seat assembly 100, each of the locking guides 410 automatically moves into the open space 702 of the respective slot 412 when the seat assembly 100 in the folded position moves forward to its maximum extent, i.e., the maximum restraining distance of the seat cushion 102. To this end, the locking guide 410 is disengaged from the slot 412. In this case, the seat assembly 100 can be easily detached from the cushion frame 104 by simply detaching the seat assembly 100 from the cushion frame 104. Referring to fig. 8, the seat assembly 100 may be removed or withdrawn from the cushion frame 104 of the vehicle. The seat assembly 100 may even be removed from the vehicle to increase the cargo space of the vehicle.
Fig. 9A and 9B illustrate perspective views of a seat assembly provided with a soft lock in accordance with an embodiment of the present invention. The seat assembly 100 may include a soft lock 902 to prevent inadvertent locking or rebound of the back frame 106 on the seat cushion 102 due to movement of the vehicle when the seat assembly 100 is in the folded position. The soft lock 902 may include any one or combination of straps, limiters, straps, hooks, stops, and the like. As shown in fig. 9B, the soft lock 902 may include a strap 904 with a lock 906 to prevent the back frame 106 on the seat cushion 102 from springing back.
Accordingly, the present invention provides a seat assembly 100 for a motor vehicle, the seat assembly 100 being selectively movable between a design position, a reclined position, and a folded position, and maximizing occupant comfort and storage or cargo space of a cabin of the vehicle. The seat assembly 100 is reliable, compact, and cost-effective, and includes a simple mechanism for transitioning between the design seating, reclined, and folded positions. The seat assembly 100 enhances occupant comfort through simultaneous movement of the seat cushion 102 and the back frame 106 by a simple and inexpensive mechanism. The seat assembly 100 utilizes a seat cushion and back frame of a simple design, thereby reducing its materials, processes and costs. The seat assembly 100 can be retrofitted with a conventional seating assembly without requiring significant changes to vehicle/environment accommodation. Those skilled in the art will appreciate that the seat cushion 102, back frame 106, and other components of the seat assembly 100 shown in the figures are merely exemplary representations and may be adapted for use with any vehicle type and vehicle interface.
In the preceding detailed description, reference has been made to the accompanying drawings which form a part hereof, and in which is shown by way of illustration the best mode presently contemplated for carrying out the invention. However, such description should not be taken as limiting the scope of the present unit. The construction thus conceived is susceptible of numerous modifications and variations, all of which can be replaced by technically equivalent elements.
