An adequate mechanical stiffness and strength are afforded to a tumble seat or a vehicle seat having a latch mechanism provided in a rear end of the seat cushion. A cushion frame (F1) of the seat includes a side frame (5) extending in a fore and aft direction, and the side frame includes a first member (10) comprising a channel member having an open side facing sideways and a second member (11) attached to the first member so as to form a closed cross section jointly with the first member, and extending downward further than the first member. A latch mechanism is positioned under the first member and attached to the second member.

A rear seat latch release device is easily installed to a portion of a rear seat holding mechanism so the rear seat can be released and more effectively folded down. The rear seat latch release device is specifically designed to surround the factory latch, and allow a pull strap to be added, which can more easily and effectively operate the rear seat latch. Components of the rear seat latch release device are designed to easily cooperate with several variations in the factory latch, thereby allowing installation in many different situations.

A multi-channel seat mounting wire retention bracket for a vehicle subjectable to an external force event and including a body structure and a seat having a seat mounting wire includes a body structure attachment portion and a wire retention portion. The body structure attachment portion is attachable to the body structure. The wire retention portion is configured to form a wire installation channel and a wire catch channel. The wire installation channel is configured to receive and retain the seat mounting wire when the seat is installed in the vehicle and to allow removal of the seat mounting wire when the seat is removed from the vehicle. The wire catch channel is configured to receive and retain the seat mounting wire during the external force event.

A seat-back adjustment system for a seat for a vehicle may include a frame member configured for attachment to a support structure of the vehicle, and a rack arrangement movably attached to the frame member. The rack arrangement may include an adjustment rack and a locking rack. A driving arrangement may include at least one gear intermeshing with the adjustment rack and operable to move the rack arrangement relative to the frame member, and a locking arrangement may include at least one locking element operable to engage the locking rack when the vehicle experiences at least a predetermined negative acceleration.

A locking device (100), especially for locking a backrest (4) of a vehicle seat (1) to a vehicle structure (6), includes a rotary latch lock (20) for locking a mating element (8). The locking device (100) further includes an ejection lever (133) which, in an unlocked state of the rotary latch-type lock (20), moves the mating element (8) relative to the rotary latch-type lock (20) by actuating an operating handle (121).

A vehicle seat (1) includes a structural part (3) which has a lock connection plate (60) and a locking unit (10) which is fixed to the lock connection plate (60). The locking unit (10) has at least one bearing bolt (51) with a passage opening (55). The lock connection plate (60) also comprises at least one mating contour (62) which projects into the passage opening (55) in the at least one bearing bolt (51).

In a seat reclining device, a seatback frame forming a skeleton of a seatback is coupled to a seat cushion frame to be rotatable about a shaft with respect to the seat cushion frame. One end portion of a first sliding bracket is rotatably coupled to a middle portion of the seatback frame by a driving unit. The other end portion of the first sliding bracket extends toward a vehicle body located behind the seatback. A second sliding bracket is mounted on the vehicle body located behind the seatback and extends toward the first sliding bracket in a front and rear longitudinal direction to be connected to the first sliding bracket. The second sliding bracket is configured to guide a sliding movement of the first sliding bracket while the first sliding bracket is being rotated.

A latch mechanism for a vehicle seat includes a latch, a plate and a second cam. The latch is movable between a first position in which the latch is engaged with a striker and a second position in which the latch is disengaged from the striker. The plate defines an arcuate slot. The second cam is coupled to the plate and includes a body and a protrusion extending outwardly from the body. The protrusion is received in the arcuate slot and is configured to traverse the arcuate slot when the latch is in the first position.
