A sliding device for a vehicle seat is provided. The sliding device includes a pair of parallel slideways, each of which comprises a lower rail, an upper rail slidably mounted to the lower rail and a latch for allowing/preventing a movement of the upper rail relative to the lower rail. A releasing member is provided for driving the latches to a position in which the upper rails are free to move relative to the lower rails. Each latch has a rear portion which is bent into a “U”-like shape and comprises a lower leg carrying latching elements configured to cooperate with corresponding latching elements provided in the lower rail and an upper leg configured to engage the releasing member. The design of the latches improves the reliability of the sliding device.

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 sliding device for a vehicle seat includes a pair of tracks, each having a lower rail and an upper rail, and a locking arrangement having a pair of locking assemblies, each including locking pins for locking a respective one of the upper rails to a respective one of the lower rails. The locking arrangement includes a releasing assembly for driving the locking pins of each of the locking assemblies to an unlocking configuration. The releasing assembly includes a releasing member and a pair of connecting members. The connecting members are each in a force transmission connection with the releasing member and with the locking pins of a respective one of the locking assemblies. The connecting members are entirely received within the tracks, and the releasing assembly is configured to convert rotational movement of the releasing member into linear movement of the locking pins of each of the locking assemblies.

A sliding device for a vehicle seat is provided with a locking arrangement including a pair of locking assemblies, one for each track of the sliding device. Each track has an upper rail and a lower rail, and each of the locking assemblies includes a plurality of locking pins for locking one of the upper rails to a respective one of the lower rails. The locking arrangement further includes a releasing assembly for driving the locking pins of the locking assemblies to an unlocking configuration. The releasing assembly comprises a releasing member and a pair of connecting members, each of which is connected in a force transmission connection with the releasing member and the plurality of locking pins of one of the locking assemblies. Each of the connecting members is entirely received inside a respective one of the tracks, whereby the locking arrangement has a very compact design.

A safety device for a lock mechanism may have a housing that encapsulates the lock mechanism. The housing may have at least one opening, through which at least one adjustment element coupled to the lock mechanism is guidable. The at least one opening may have a sealing element. A seat track for a seat is also disclosed. The seat track may have a first track assembly with at least one track member, a second track assembly with at least one further track member, and a lock mechanism configured to lock an adjustment of the seat.

A long rail assembly for repositioning a seat assembly in a vehicle comprising an inboard lower channel, an inboard manual drive assembly, an outboard lower channel, an outboard manual drive assembly, a central lower channel, and a power drive assembly. The inboard lower channel is adapted to extend longitudinally along a floor of the vehicle. The inboard manual drive assembly is coupled to the seat assembly and slidably coupled to the inboard lower channel The outboard lower channel is adapted to extend N longitudinally along the floor of the vehicle. The outboard manual drive assembly is coupled to the seat assembly and slidably coupled to the outboard lower channel The central lower channel is adapted to extend longitudinally along the floor of the vehicle. The power C drive assembly is coupled to the seat assembly and slidably coupled to the central lower channel. The power drive assembly power drives the seat assembly along the central lower channel

A seat length adjuster for a vehicle seat may have two rail pairs, each pair formed by an upper rail and a lower rail. The upper rail is provided with openings and the lower rail has through holes. At least one spring-loaded, movable locking member may be provided. The locking member carries toothlike protrusions on its two opposite lengthwise sides, which are movable from a released position into the locked position both into the openings and into the through holes. The openings and/or the through holes have contact regions for the toothlike protrusions of the locking member and at least some of the toothlike protrusions have a respective undercut on both tooth flanks. In the locked position a projecting edge resulting from this on the respective tooth flank lies opposite the contact region and/or touches this contact region.

A sliding device for a vehicle seat is provided with a pair of tracks and an improved releasing assembly. The sliding device comprises a pair of locking assemblies, one for each track, each including a plurality of locking pins for locking upper rails of the tracks to lower rails of the tracks. The sliding device further includes a releasing assembly for driving the locking pins to an unlocking configuration for adjusting the position of the vehicle seat. The releasing assembly comprises a releasing member having a pair of substantially parallel arms pivotally connected to the tracks, a crossbar extending transversely to the tracks and provided at each end with an engaging assembly for engaging the locking pins of the respective locking assembly, and a pair of connecting members configured to convert a rotational movement of end portions of the arms into a translational movement of the crossbar.

A safety device for a lock mechanism may have a housing that encapsulates the lock mechanism. The housing may have at least one opening, through which at least one adjustment element coupled to the lock mechanism is guidable. The at least one opening may have a sealing element. A seat track for a seat is also disclosed. The seat track may have a first track assembly with at least one track member, a second track assembly with at least one further track member, and a lock mechanism configured to lock an adjustment of the seat.
