A longitudinal adjuster (3) for a vehicle seat (1) includes at least one rail pair (7), including a lower rail (9) and an upper rail (11), which can be moved longitudinally in relation to the lower rail (9). At least one locking unit (13) locks the upper rail (11). At least one actuating element (5) releases the locking of the upper rail (11). The locking unit (13) includes at least one locking element (15) and at least one spring element (17), which are operatively engaged with each other. The spring element (17) is interlockingly and frictionally connected to the upper rail (11) by an insertion locking connection (S). The spring element (17) applies a preloading force to the actuating element (5) and to the locking element (15). A vehicle seat (1) is also provided with at least one such longitudinal adjuster (3).

A vehicle seat slide mechanism via which a seat assembly is slidably mounted on a vehicle floor is provided with: a lower rail that is mounted on the vehicle floor; an upper rail which is slidably attached on the lower rail and on which the seat assembly is attached; a lock mechanism that locks the upper rail on the lower rail in a releasable manner; and a gap reduction member that is provided between a first face formed at the lower rail and facing in a substantially vertical direction and a second face formed at the upper rail and facing to the first face.

A longitudinal adjuster (3), for a vehicle seat (1), includes a lower rail (9), an upper rail (11), moveable in relation to the lower rail (9) in a longitudinal direction (x), and a locking unit (13) for locking the upper rail (11) to the lower rail (9). The locking unit (13) includes two locking elements (VR), which, in order to lock the upper rail (11) and the lower rail (9), engage in the upper rail and the lower rail in a blocking manner in steps such that one of the locking elements (VR) pre-locks the upper rail (11) and the lower rail (9) with play in a pre-locking step and one of the locking elements (VR) locks the upper rail (11) and the lower rail (9) without play in a locking step. A vehicle seat (1) including such a longitudinal adjuster (3) is provided.

A seat sliding device for vehicles includes lower and upper rails and a locking member for locking or unlocking the upper rail relative to the lower rail. The upper rail is equipped at a lower end of its downward side wall portion with a lower inward corner portion formed of a raised wall portion and a bottom wall portion. The locking member has an axial portion that is placed on and biased against the lower inward corner portion of the upper rail such that the locking member is swingable about an axis of the axial portion to lock or unlock the upper rail relative to the lower rail. This seat sliding device makes it possible to reduce the number of parts and improve operation stability of the locking member.

A vehicle seat including a slide lock mechanism which is configured to lock a locked part provided to a second rail side to a locking part provided to a first rail side or release the locking of the locked part and the locking part, and a walk-in mechanism including a shifting preparation mechanism part which is provided to the first rail side, a holding mechanism part which is provided to the second rail side and holds a locking released state of the slide lock mechanism, and a holding release mechanism part which is provided to the second rail side and shifts the locking released state of the slide lock mechanism to a state where the slide lock mechanism is capable of shifting to the locked state.

A passenger support includes a vehicle seat and a foundation having a lower track and an upper track. The lower track is coupled to a floor of a vehicle in a fixed position relative the floor. The vehicle seat is coupled to the upper track to slide back and forth relative to the lower track.

A power long rail assembly is attached to a vehicle floor for repositioning vehicle seats in a vehicle between a plurality of seating positions. The power long rail assembly includes a fixed long rail and a power rail drive assembly configured to travel along the fixed long rail. The power rail drive assembly has an upper channel having a driving wheel configured to frictionally and/or meshingly engage with the fixed rail, a fore/aft motor operatively coupled to the driving wheel, a latch assembly for locking the upper channel to the fixed long rail, and a latch release mechanism having a latch motor operatively coupled to a release plunger for automatically unlocking the latch assembly from the fixed long rail, and a fore/aft button operatively coupled to the fore/aft motor and to the latch motor to selectively activate the fore/aft motor and the latch motor.

A seat adjuster may include an end stop bracket and an easy entry lever. An easy entry lever may be configured to rotate between a first position in which the easy entry lever engages the end stop bracket and prevents movement of a seat from a comfort range into an easy entry range, and a second position in which the easy entry lever does not prevent movement of the seat from the comfort range into the easy entry range. A cross member may be connected via one or more cables to one or more comfort lever activators.

A track adjuster may include a cross member, an end stop bracket, an adjustable end stop lever, and/or a connection member that may be configured to actuate the adjustable end stop lever. The adjustable end stop lever may be configured to rotate between a first position in which the adjustable end stop lever engages the end stop bracket and prevents movement of a seat from a comfort range into an easy entry range, and a second position in which the adjustable end stop does not prevent movement of the seat from the comfort range into the easy entry range. The cross member may be configured for rotating independently of the adjustable end stop lever.

A rail pair (1), for a vehicle seat (10), includes at least a lower seat rail (S1) and an upper seat rail (S2), which engage around one another in such a way that a rail profile is formed and which can be moved in relation to each other in a longitudinal direction (L) and can be interlocked by a rail locking device (2). Rolling elements (4) are arranged between the seat rails (S1, S2) in an interaction region. The upper seat rail (S2) includes two side walls (S2.1, S2.2), which two side walls (S2.1, S2.2), in a vertical orientation, protrude largely in parallel and perpendicularly from a bottom region (S2.3). One of the side walls (S2.2) is bent outward in a continued course in some regions of the longitudinal direction (L).
