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 device for unlocking a seat for a vehicle includes a base frame mounted on a movable rail of a seat rail, a seat frame mounted on the base frame to be able to tilt, a lock pin fixed to a side of the seat frame, a support bracket mounted on a floor panel, and a lock plate rotatably mounted on a side of the base frame, and configured to be locked to the lock pin when coming in contact with the support bracket and to be unlocked from the lock pin when coming apart from the support bracket, whereby it is possible to automatically unlock a seat when it is required to tilt the seat through a walk-in mechanism to secure a passage for a passenger to get in/out of a vehicle.

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 track for a vehicle seat comprising: a lower rail; an upper rail, mounted sliding relative to the lower rail in a longitudinal direction; where a bolt has means of pivoting between a manual lever and an attachment part comprising a first part and a second part belonging respectively to the manual lever and of the attachment part, or vice versa, hinged one relative to the other around said axis of rotation. According to the present disclosure, the first part and the second part comprise means for clipping, mutually engaging, allowing an assembly of the manual lever and the attachment part by elastic deformation of the one at least of the clipping means belonging to the first part and/or to the second part.

A latching mechanism configured to secure a first component and a second component. The latching mechanism includes a locking plate that operatively engages a first latch plate and a second latch plate. The plates each include an end that inserts into a slot located on the second component, therein securing the first component to the second component. Actuation of the latching mechanism displaces the plates, therein releasing the ends from the slot and allowing for movement of the first component in relation to the second component.

A sliding device includes a fixed rail, a movable rail, a lock plate, and a spring member. A seat body is fixed to the movable rail, and the movable rail is slidable relative to the fixed rail. The lock plate is held by the movable rail, and is displaceable 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 is released. The spring member exerts an elastic force to maintain the lock plate in the locking position.
