A crash-arresting unit for a vehicle seat may have a locking element and an actuating unit. The locking element can be brought into form-fitting engagement with a mating element via the actuating unit. The actuating unit may be an electromechanical actuating unit having a fusible wire, where destruction of the fusible wire frees a movement of the locking element in the direction of the mating element.

A vehicular locking device includes a bore having first and second ends. A gas generating device is proximate the first end. A piston is movable along an interior of the bore. The vehicular locking device includes first and second plates. The second plate includes an aperture. Activation of the gas generating device accelerates the piston through the aperture and the second plate preventing displacement of the second plate.

An adjustment mechanism for a vehicle seat includes an actuator and a driven member. The actuator is coupled to the driven member to cause the driven member to move or be freed to move in response to activating the actuator.

A rail for vehicle seat that has first and second sliding rail members driven by a motorized drive mechanism. The rail further includes a mechanical latch actuated when crash conditions are detected.

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 rail for a vehicle seat having first and second sliding rail members driven by a motorized drive mechanism. The rail further comprises a mechanical lock actuated by a relative movement between the motorized drive mechanism and the second rail member in the event of an accident.

An inertial latch for a motor vehicle armrest is rotatably connected to a a bracket mounted to a support structure; an armrest interfacing component is disposed in an arcuate slot in the bracket, the slot extending from a first to a second end; a primary pawl rotatable from a first to a second position and limiting motion of the interfacing component in the slot; a secondary pawl rotatable from a third position to a fourth position and limiting motion of the primary pawl; a stop limits motion of the secondary pawl. The armrest articulates from a closed to an open position, the interfacing component moves through the entire slot when the primary pawl is in the first position, the interfacing component is held within a portion less than the entire slot when the primary pawl is in the second position, and the interfacing component is releasable from the portion.

The present disclosure provides a seat track mechanism installed beneath a vehicle seat in order to move the vehicle seat in the forward and backward directions. A monotrack mechanism, to which a monopost structure and a single rail structure are applied, is installed at the bottom of the seat. The seat track mechanism includes a structure for hook-engaging lower and upper rails constituting the mono track mechanism by hook guides, thereby being capable of securing sufficient strength upon head-on or rear-end collision. The present disclosure also provides a seat track mechanism for a vehicle including a locking mechanism capable of enhancing stability of a passenger through structural reinforcement given at the bottom of the vehicle when it is necessary to ensure safety of the passenger in a situation such as collision or sudden stop or the like.

A longitudinal adjuster (10) for a vehicle seat (1), including at least one rail pair which is formed from a first seat rail (12) and a second seat rail (14), the seat rails (12, 14) of the rail pair encompassing one another and being movable relative to one another in the longitudinal direction (x) and being able to be locked to one another via a locking device (16), the locking device (16) having at least one locking element, in particular at least one latching plate (18) which is movable in the vertical direction (z), the longitudinal adjuster (10) having an additional locking means (30) which is normally inoperative and is actuated only in the event of a crash by mass inertia. A vehicle seat (1), in particular a motor vehicle seat, includes a seat part (2) and a longitudinal adjuster (10).

The invention relates mainly to a seat comprising a backrest carrying on a rear face side a tray table that can be moved between a deployed position and a stowed position, said tray table comprising a latch that can be moved between an unlocked position and a locked position, characterized in that said tray table further comprises a locking system configured to hold the tray table in a stowed position following the deformation of said seat during an impact.
