A sliding device includes a fixed rail, a movable rail, a lock plate, a spring member, and a fixing structure. The lock plate is displaced between a locking position where the lock plate engages with the fixed rail and restricts slide of the movable rail and a non-locking position where the restriction of slide is released. The spring member exerts an elastic force to maintain the lock plate in the locking position. The fixing structure includes a tapered portion of the spring member and a press spring portion that presses the tapered portion toward a hole of the movable rail.

A rail assembly includes a track assembly defining an interior channel, a shuttle assembly received within the interior channel, and a carriage assembly coupled to the track assembly. The shuttle assembly includes a lock assembly. The carriage assembly includes a trigger assembly. The trigger assembly includes a trigger cam and an actuator cam coupled to the trigger cam. The actuator cam actuates the carriage assembly between locked and unlocked configurations relative to the track assembly.

The present invention relates to a sliding device for a vehicle seat provided with an improved locking arrangement. Said locking arrangement comprises a pair of locking assemblies (1a, 1b), one for each track of the sliding device, each including a plurality of locking pins (3a, 3b) suitable for locking the upper rails of the tracks to the respective lower rails. Said locking arrangement further includes a releasing assembly for driving said locking pins to an unlocking configuration for adjusting the position of the vehicle seat. Said releasing assembly comprises a releasing member and a pair of connecting members (7a, 7b), which are in a force transmission connection with the releasing member, on one hand, and with the locking pins (3a, 3b) of a respective locking assembly, on the other hand. According to the invention, such connecting members (7a, 7b) are configured to slide along a substantially linear path and to consequently drive the locking pins along a substantially linear path. Such construction enhances the reliability of the locking arrangement and provides for a greater flexibility in designing the locking arrangement itself.

A motor vehicle seat floor slide rail includes a lower slide rail assembly (100), an upper slide rail assembly (200) and a gap elimination mechanism (230, 230′), with a shaft-provided gap elimination cam (231L, 231R), on an upper slide rail longitudinal end, having a rotation center (232a) axis perpendicular to an upper rail longitudinal direction. A locking window face (117L, 117R) has an aluminum slide rail (110) longitudinal gap elimination face (113L, 113R). A rail locked state has a cam face (2311L, 2311R) in contact with the gap elimination face to eliminate a Y and Z direction gap. In a rail unlocked state, a locking mechanism (240) drives the gap elimination cam, such that the cam face loses contact with the gap elimination face. The gap elimination cam moves in linkage with the locking mechanism, reducing sliding friction, and having the advantage of low sliding assistance motive power.

A rail assembly includes a track assembly defining an interior channel, a shuttle assembly received within the interior channel, and a carriage assembly coupled to the track assembly. The shuttle assembly includes a lock assembly. The carriage assembly includes a trigger assembly. The trigger assembly includes a trigger cam and an actuator cam coupled to the trigger cam. The actuator cam actuates the carriage assembly between locked and unlocked configurations relative to the track assembly.

A seat track mechanism for a vehicle seat. The seat track mechanism may include an upper track, a lower track, a striker, a lever, and a pawl. The lever may be rotatable about a lever axis. The pawl may be rotatable with respect to the lever about a pawl axis when the striker engages the pawl.

A slide rail for a vehicle seat comprises first and second slide members lockable by a lock which comprises several locking members suitable for entering holes that are part of the first slide member. The lock is mounted on the second slide member so as to provide translational clearance between the lock and the second slide member.

A vehicle seat slide device includes an upper rail, a lower rail, a lock mechanism that restricts movement of the upper rail relative to the lower rail, and a lock release mechanism that performs an unlocking action with the lock mechanism. The lock release mechanism includes an input lever and a release lever. The release lever includes a longitudinal extension, a widthwise extension, and a vertical extension. The release lever is configured so that the vertical extension presses an unlock element as the input lever presses the widthwise extension from above.

A seat adjustment device for a vehicle comprising a base member, a pair of lower rails, a pair of upper rails, a pair of latch assemblies, a handle, and a top member, wherein the adjustment device is adjustable within a range toward the front of the vehicle or the rear of the vehicle.

A modular and electromechanically integrated easy-entry mechanism includes an easy-entry mechanism, manufactured independently of slide rail assemblies, and mounted on upper slide rails in the slide rail assemblies by fasteners. A total travel of slide rails is divided into a comfort travel for front-rear adjustment of a passenger and an easy-entry travel for increasing an easy-entry/exit space for a passenger in the third row seating. The unlocking of the slide rails is mechanically maintained in the easy-entry travel, and the slide rails are ensured to be locked at the front-most position of the comfort travel when a seat is retracted. The easy-entry mechanism is driven manually or by electric power, and acts independently on unlocking pins in slide rail locking mechanisms to unlock the slide rail assemblies. The easy-entry mechanism is modularly designed, easy to manufacture, mount, and replace, and does not affect the existing slide rail manufacturing process. Since the easy-entry mechanism independently acts on the unlocking pins in the slide rail locking mechanisms to unlock the slide rail assemblies, an existing manual slide rail unlocking module is not affected.
