Abstract: A dual release actuator for a vehicle seat includes a motor, a cable carrier configured to receive power of the motor, thereby rotating to selectively pull one of two different cables, a Hall sensor to sense rotation of the motor, and a controller configured to count a sensing pulse of the Hall sensor for controlling rotation of the motor.

Abstract: A device for preventing rotation of a vehicle seat rail is described. The device prevents an upper rail on the center side of a vehicle from rotating when a forward load is applied to a vehicle seat, thereby preventing a lock plate from being fractured due to rotation of the upper rail.

Abstract: A vehicle seatback folding device includes: a cushion bracket; a back side frame rotating on the cushion bracket; a spring mounting bracket coupled to rotate integrally with the back side frame around a hinge-coupling part; a return spring for applying, to the back side frame, elastic restoring force for rotating the back side frame in the folding direction of a seatback; and a reverse spring supported in a state in which a first end portion is caught by the spring mounting bracket and a second end portion is caught by a first spring support end.

Abstract: The present disclosure provides a double-folding unlocking device of a rear seat for a vehicle. The double-folding unlocking device of a rear seat is capable of preventing the occurrence of excessively tight fitting and deformation of components due to excessively tight contact between bracket members when a seatback is rotated in an opposite direction while the seatback is folded or unfolded.

Abstract: A seat track mechanism for installing beneath a vehicle seat in order to move the vehicle seat in the forward and backward directions includes a monotrack mechanism, to which a monopost structure and a single rail structure are applied. The seat track mechanism includes a structure for hook-engaging lower and upper rails constituting the mono track mechanism by hook guides. The single rail structure applied to the seat track mechanism is capable of not only reducing actuating force required for operation, but also preventing creation of excessive clearance upon stopping.

Abstract: A seat track mechanism for installing beneath a vehicle seat in order to move the vehicle seat in the forward and backward directions includes a monotrack mechanism, to which a monopost structure and a single rail structure are applied, installed at the bottom of the seat. Upper and lower rails of the mono track mechanism hook-engage with each other by hook guides. Accordingly, the seat track mechanism can secure sufficient strength upon head-on or rear-end collision.
