A motor vehicle comprises an upper back support comprising a substantially U-shaped tubular member pivotally attached at a first end to one of a pair of opposed lateral seatback frame members and pivotally attached at a second end to the other of the pair of opposed lateral seatback frame members, a substantially rigid planar base attached to a central portion of the tubular member, a latch operably coupling the first end of the tubular member to the one of a pair of opposed lateral seatback members to restrain the tubular member in one of a plurality of positions between a stowed position and a fully raised position, and a cushion disposed above the upper back support to form a movable exposed surface.

A motor vehicle comprises an upper back support comprising a substantially U-shaped tubular member pivotally attached at a first end to one of a pair of opposed lateral seatback frame members and pivotally attached at a second end to the other of the pair of opposed lateral seatback frame members, a substantially rigid planar base attached to a central portion of the tubular member, a latch operably coupling the first end of the tubular member to the one of a pair of opposed lateral seatback members to restrain the tubular member in one of a plurality of positions between a stowed position and a fully raised position, and a cushion disposed above the upper back support to form a movable exposed surface.

An object of the present invention is to provide a vehicle seat in which a vacant space produced after tipping up a seat cushion can be effectively used as a luggage storage space. The vehicle seat includes: a support leg (6A, 6B, 6C) to support weight related to a seat cushion (2); a leg holding member (8) to hold a lower part (6C) of the support leg (6A, 6B, 6C); and a slide mechanism (18A, 18B) to move the seat cushion (2) and a seat back (3) in a front/back direction. The seat has a tip-up function to rotate the seat cushion (2) so that its front part is in a higher position than its rear part and the seating surface of the seat cushion (2) and the front surface of the seat back (3) face each other, in which the leg holding member (8) is located at a part (18A) of the slide mechanism (18A, 18B) which moves along with the seat cushion (2) and the seat back (3).

An adjustment device (1) for a rear seat bench (2) includes a seat part (3) and a divided backrest (4) that has at least one car body-side rest segment (4.1) and at least one adjacent rest segment (4.2). At least one of the car body-side rest segment (4.1) and the adjacent rest segment (4.2) is foldable from a use position into a non-use position, or vice versa, when in an unlocked state. A spring unit (7) is arranged between the adjacent rest segments (4.1, 4.2) and is functionally connected to the rest segments (4.1, 4.2) in a mechanical manner. A seat arrangement is also provided including such an adjustment device (1).

A number of variations may include a vehicle seatback support pivotally connected to the vehicle body, and wherein the seatback support includes an integrated storage cavity.

A vehicle seating assembly having a seat including a support frame. A seatback is pivotally coupled with the seat and is adjustable between a passenger support position configured to support the weight of a passenger and a cargo position. The seatback is folded forward to a substantially horizontal position. A seat cushion includes a dynamic forward portion and a generally static rearward portion. An articulation feature is disposed below the forward portion of the seat cushion. The articulation feature is operable between a deployed and a non-deployed position. Movement to the deployed position results in the dynamic forward portion of the seat cushion being adjusted to a raised position. Movement to the non-deployed position results in the dynamic forward portion of the seat cushion being adjusted to a lowered position that allows the seatback to fold forward to the cargo position.

A vehicle seat capable of housing a seat main body includes a seat pivot shaft to which the seat main body is connected to be pivotable, and a detachable leg whose upper end is mounted to the seat main body and whose lower end is detachably held onto a leg holding member on a vehicle body floor. When the seat main body moves from a housed state side to a usage state side, a leg guide portion causes a cushion abutting portion to abut a base abutting portion in advance, thereby guiding the detachable leg moving together with the seat main body to pass above a leg movement inhibiting portion which is a portion of a support base.

A vehicle seat having a seat back and seat cushion connected thereto, the seat back and seat cushion being retractable to a retraction floor disposed lower than a vehicle body floor, is described. The vehicle seat includes: a support base connected to the body floor, disposed below the seat cushion, and pivotally connected to a lower end of the seat back; a detachable leg having an upper end attached to the seat cushion and a lower end connectable to the support base; a leg retaining member attached to the support base and configured to detachably retain the lower end of the detachable leg; and a base cover that covers the support base. The leg retaining member is disposed at a rear side of a front end of a portion of the base cover in a front to back direction that is configured to cover the support base from above.

A multi-linkage hinge assembly is provided for pivoting a seat cushion between flat and upright positions. The hinge assembly includes a base bracket, a seat bracket having a support surface, a front linkage member pivotally attached between the seat bracket and base bracket, a rear linkage assembly having a lower linkage member pivotally attached to an upper linkage member, and a tie linkage connecting the front linkage member to the rear linkage assembly. The tie linkage synchronizes movement of the front linkage and rear linkage assembly when the hinge is operated to move between an upright and flat position.

An object is to provide a vehicle rear seat frame wherein impact caused by a housed seat toward the vehicle front is mitigated in a case of rear-end collision. Seat cushion side frames are disposed on both ends, with respect to the vehicle lateral direction, of a seat cushion frame, and include first weak portions having less strength than other portions in the vehicle longitudinal direction in a folded state. Seat back side frames disposed on both ends, with respect to the vehicle lateral direction, of a seat back frame include second weak portions having less strength than other portions in the vehicle longitudinal direction in a folded state.
