In a slide rail device for use in a vehicle , a lock spring support portion of an upper rail includes an upward-downward movement restriction support portion. The upward-downward movement restriction support portion includes an open holding portion which is open at a top thereof and holds a supported portion of a lock spring and an uplift prevention projection which is formed projecting into the open holding portion so as to overlap the supported portion of the lock spring, which is held by the open holding portion, in the upward and downward directions.

In a slide rail device for use in a vehicle, a lock control member comprises a pair of facing walls which face a pair of side walls of an upper rail and extend in upward and downward direction, and a pair of anti-rattle projections which project from the pair of facing walls toward the pair of side walls of the upper rail.

A seat slide device includes a pair of sliders each including a fixed rail, a movable rail slidably guided by the fixed rail, a bracket on the movable rail configured so that front and rear sides swing opposite to each other in a vertical direction with a longitudinal-intermediate part as a fulcrum, a support bracket supported on the bracket via a hinge and configured to rotate in only one direction from a predetermined orientation about an lateral-direction axis relative to the bracket, a movement-restricting portion configured to restrict sliding of the movable rail while a rear part of the bracket is raised and to release the restriction while the rear part of the bracket is lowered; and a towel bar connecting each support bracket. The hinge part prohibits a rotation of the support bracket while the towel bar is lifted and permits the rotation while the towel bar is lowered.

A seat for a vehicle includes a seat cushion and an adjustment and suspension device having a base fixed to the frame and a supporting plate fixed to the seat cushion movable in translation relative to the base in a direction of elevation. The seat also has a restraint system that includes: at least one restraint member fixed to the frame, the restraint member defining at least one through opening extending along a main direction of elongation substantially parallel to the direction of elevation; and at least one restraint element fixed to the supporting plate, the through opening of the restraint member receiving the restraint element free in translation along the main direction of elongation.

A seat sliding structure for a vehicle includes: a pair of left and right slide rails that include upper rails, which are attached to a lower portion of a vehicle seat, and lower rails, which support the upper rails such that the upper rails can slide in a vehicle longitudinal direction; rail guiding members that are fixed to a floor panel, and that support the lower rails such that the lower rails can slide in the vehicle longitudinal direction between a driving position at a vehicle front side and a relaxation position at a vehicle rear side; and a locking mechanism that locks movement of the slide rails at the relaxation position, and that releases a locked state when a frontal collision of the vehicle is detected or predicted.

A seat position detection apparatus for a vehicle seat which is guided using a seat rail in a floor rail of the vehicle. The seat position detection apparatus has a lock for the longitudinal setting of the seat rail and the floor rail in relation to one another, and a mechanical memory device that has a position determination unit and a position detection unit, which may be started symmetrically from both directions of the longitudinal adjustment of the vehicle seat to define a vehicle seat position.

A slide rail for a motor vehicle seat, comprises a first profile, a second profile and an interior space which extends in a longitudinal direction, the interior space extending between the first profile and the second profile, the second profile being movable relative to the first profile, rolling elements which are arranged in the interior space and configured to guide the movement of the second profile relative to the first profile in the longitudinal direction, and a runner which is arranged in the interior space and holds the second profile relative to the first profile in a support direction perpendicular to the longitudinal direction, wherein the runner is selectively connected to the first profile or to the second profile.

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 gearbox includes: the first helical gear; the second helical gear to engage with the first helical gear; a casing including a first member disposed in proximity to the first helical gear and a second member disposed in proximity to the second helical gear; a screw for fastening the first member with the second member, and disposed closer to the first helical gear than an engagement position between the first helical gear and the second helical gear and penetrating at least the second member; and a clip disposed closer to the second helical gear than the engagement position, and formed of a closed curve in such a manner that the first member end and the second member end are enclosed therein.

A seat track assembly including a first rail configured to move along a second rail. The assembly may include a roller cage disposed at least partially between the first rail and the second rail. In embodiments, the assembly includes a stopper that projects from an inner surface of the second rail and is configured to restrict movement of the roller cage while the movement of the first rail relative to the second rail is independent of the stopper.
