A long rail assembly attached to a vehicle floor for repositioning vehicle seats in a vehicle between a plurality of seating positions. The long rail assembly includes a fixed long rail having a C-shaped cross-section in profile and an elongated opening in a side wall of the long rail, a power rail drive module configured to travel along an interior of the long rail and having at least one striker extending laterally away from the rail drive module through the elongated opening in the side wall of the long rail, and a vehicle seat having at least one leg releasably coupled to the at least one striker by a seat latch assembly.

A vehicle seat sliding device for sliding a seat includes a fixed rail, a movable rail, a rolling element, and at least one rolling element holder. The fixed rail is for a floor of a vehicle. The movable rail is slidably engaged with the fixed rail and is mounted to the seat. The rolling element includes an outer circumferential surface for abutting an abutment surface of the fixed rail. The at least one rolling element holder is mounted to the movable rail and holds the rolling element so as to be rotatable and slidable along a longitudinal direction of the movable rail. The at least one rolling element holder is configured such that a distance between a rotation axis of the rolling element and the abutment surface becomes smaller as the rolling element slides toward one side in the longitudinal direction of the movable rail.

A rolling element holder holds a rolling element rotatably and slidably. A biasing unit biases the rolling element holder toward a first surface of a fixed rail. A projection is provided on the rolling element holder, and faces a second surface opposite to the first surface. The rolling element holder is configured so that a distance in an up-down direction from a contact point between the rolling element and the first surface to an end portion of the projection on the second surface side becomes larger as the rolling element approaches an end on one side in a slidable range of the rolling element, and so that the projection is brought into contact with the second surface at least when the rolling element is at the end on the one side.

A locking device for a vehicle seat. The locking device including at least one securing section provided on an unlocking element of the locking device, which in a locking position of a locking element of the locking device positively engages in a form-fit area of the locking element and blocks a displacement of the locking element into its unlocking position.

The present disclosure relates to a system for locking a continuously adjustable slide for a vehicle seat, comprising; the slide comprising a first, lower slide element configured to be fixed to a vehicle floor, and a second, upper slide element configured to slide along the first slide element, a system for locking by bracing comprising: a rail, extending lengthwise along the at least one slide, stationary relative to the first slide element, a first blocking member and a second blocking member, mounted integral with the second slide element, in positions offset along a longitudinal axis of the rail, the first blocking member configured to brace against the rail, under the action of two wedging members blocking by wedge effect in slots.

The present disclosure relates to a gap prevention structure of a seat rail for a vehicle. The gap prevention structure includes: a lower rail configured to be fixed to a bottom of a vehicle body and to have a receiving space formed therein; an upper rail configured to have at least a portion thereof received in the receiving space and to slide in a longitudinal direction of the lower rail; a rolling bearing configured to be rotatably coupled to the upper rail and to roll and move in the receiving space in the longitudinal direction of the lower rail; and a gap prevention unit configured to limit rotation of the rolling bearing by pressing the rolling bearing while being inserted between the lower rail and the rolling bearing.
