System comprising a slide track for motor vehicle seat and a support. The slide track comprises a fixed rail and a movable rail which has an inner surface, an outer surface, and a through-window. The support comprises a body having a contact surface attached to the outer surface of the movable rail, and a tongue extending from the body to pass through the window of the movable rail and be attached to the inner surface of the movable rail. The tongue has a maximum extension into the hollow interior space E that is less than or equal to a thickness of the tongue.

A cover (11), for a rail pair (3) of a longitudinally adjustable vehicle seat (1), includes at least one bottom rail (5) affixed to the vehicle and one top rail (7) which top rail (7) is longitudinally movable relative to the bottom rail (5). The cover (11) has a cover element (11.1) arranged and placed on at least one end (7.1, 7.2) of the rail pair (3) and an integrated stiffening element (11.2), designed to stiffen at least one of the two rails (5, 7), which protrudes into an interior chamber of the rail pair (3).

A seat rail assembly capable of stably holding a position of one or more vehicle seats relative to the vehicle floor. The seat rail assembly includes an upper rail on which the seat is provided and a lower rail which is mounted to the vehicle floor. The upper rail is slidably provided within the lower rail, and incorporates an engagement assembly with a dual wedge engagement assembly to ensure constant contact between the lower and upper rails. A gearbox configured to remove lash may be provided on the upper rail for moving the upper rail relative to the lower rail.

Provided is a seat sliding device. The seat sliding device comprises a fixed-side rail, a movable-side rail, a lock portion, an elastically deforming portion, and a releasing member. The lock portion is displaceable between a restraint position and a release position. The elastically deforming portion comprises: a linear portion that is an elastically deformable portion extending in a direction approximately parallel to a longitudinal direction of the movable-side rail; and an engaging portion protruding from an extending-direction leading end portion of the linear portion in a direction approximately perpendicular to an extending direction of the linear portion. The releasing member comprises: a first engaged surface that is contactable with the engaging portion from one end side in the extending direction; and a second engaged surface that is contactable with the engaging portion from the other end side in the extending-direction.

Provided is a seat sliding device. The seat sliding device comprises a fixed-side rail, a movable-side rail, a lock portion, an elastically deforming portion, a releasing member, and a restricting portion. The movable-side rail comprises an open-sectional portion including two side walls and a lid wall. The lock portion is displaceable between a restraint position and a release position. The releasing member is provided between the elastically deforming portion and the lid wall. The restricting portion is configured to provide a space through which an insertion-side end of the releasing member is insertable between the elastically deforming portion and the lid wall.

A seat includes a seat bottom, a seat back, a seat mounting structure configured to support the seat bottom and the seat back, the seat mounting structure configured to slidably couple to the rail assembly, and an occupant restraint system including a seat belt coupled to a retractor assembly. The retractor assembly is configured to slidably couple to the rail assembly such that the retractor assembly moves along the rail assembly as the seat mounting structure is moved along the rail assembly, the occupant restraint system configured to transfer load to the rail assembly disposed in the vehicle floor.

A release device for the upper rail and the lower rail of a longitudinal seat adjustment system of a motor vehicle seat, the release device having a lever rotatably supported on the upper rail of the seat. An end of the lever interacts with the locking means and optionally releases the locking means. A handle is provided at the other end. If the handle is operated, the lever moves relative to the upper rail from a passive position to a release position and moves the locking means from a locking position to a releasing position. So the release device automatically moves into a passive position of the release device, a spring element is provided, which preloads the lever into the passive position of the lever. The spring element additionally supports the lever on the upper rail.

A power seat slide device capable of changing not only to an electric operation but also to an manual operation, and preventing half-lock in spite of a manually operable structure. For front-rear movement, a rack attached to a lower rail and a pinion meshed with the rack are used, and a driving force of a motor is transmitted to the pinion, which enables the use in an electric mode. As no slide screw is used, while the motor is not energized, rotating the pinion causes an output shaft of the motor to rotate, so that manual adjustment becomes possible.

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.
