The locking device has at least one latching plate (18), which is movable in the vertical direction (z). The latching plate has a guide pin (20) protruding in the vertical direction. The upper seat rail has an opening (22) aligned with the guide pin. A guide sleeve (24) extends into a cavity between the seat rails and is accommodated in the opening. The guide pin is guided by the guide sleeve. The upper seat rail and the guide sleeve are connectable by a bayonet catch.

A rail system (1), for a vehicle seat, includes a lower rail (3), an upper rail (5), a sliding block (7) and at least one rolling body cage (9) having rolling bodies (11). The sliding block (7) is rigidly connected to the lower rail (3). The rolling body cage (9) is movable relative to the sliding block (7), parallel to a longitudinal axis (13) of the lower rail (3), between two end positions defined by end stops (71) of the sliding block (7). The rolling body cage (9) is coupled to the lower rail (3) via the rolling bodies (11). The upper rail (5) is mounted movably on the sliding block (7) along the longitudinal axis (13) of the lower rail (3) and is coupled to the rolling body cage (9).

A compliant pivot joint is provided for rotationally coupling a link member to a frame member in a vehicle seat. The compliant pivot joint includes a cup-shaped protrusion having a cup opening formed on the link member, a shoulder bolt having a first shaft portion projecting from a bolt head and terminating at a shoulder, a bias member having a bias opening, and a fastener fixedly coupled to the frame member. The shoulder bolt is fixedly coupled to the fastener and extends through the bias opening and through the cup opening. The bias member is spaced between the cup-shaped protrusion and the bolt head and biases the bolt head away from the cup-shaped protrusion. A curved shoulder surface of the fastener is frictionally engaged with the cup-shaped protrusion and the shoulder of the shoulder bolt is frictionally engaged with an end surface of the fastener.

A motor vehicle latch, in particular a motor vehicle backrest latch, which is equipped with a locking mechanism consisting substantially of a catch and a pawl. A latch housing having a recess is also implemented. In addition, a damping means at the end side of the recess, a latch holder entering the recess in the direction of entry transferring the locking mechanism to its closed position, thereby moving against the damping means. In addition, the damping means has a plurality of recesses and at least one web. According to the invention, the web is designed as an arched web and its highest arch is convexly curved against the direction of entry of the latch holder.

Provide is a vehicle seat capable of inhibiting rattling of a seat cushion provided with a lifting device. One embodiment of the present disclosure is a vehicle seat including a lifting device for a seat cushion. The lifting device includes a pinion gear, a sector gear engaged therewith, a link rotating, together with the sector gear, with respect to the cushion frame, and a rubber member attached to the cushion frame. The link is displaced between a first position where a position of the seat cushion is lowest and a second position where the position of the seat cushion is highest. When the link is at the first position, or at the second position, or in a region between the first position and the second position, the rubber member is brought in pressure contact with the sector gear along a direction intersecting a rotational axis of the sector gear.

An object of the present invention is to provide a seat for a vehicle which is capable of smoothly and stably adjusting the reclining of a seat back by driving an electrical reclining motor 34, even if the electrical reclining motor 34 is diagonally mounted on a seat back frame structure in a case where the electrical reclining motor 34 is fixedly connected on a seat back frame structure, or even if the electrical reclining motor 34 becomes inclined due to a deformation of the seat back frame structure after such a fixedly connection. There is provided a seat 10 for a vehicle comprising a seat back frame structure 12 a lower end of which is connected to a rear end of a seat cushion frame structure 14 in such a way that the seat back frame structure 12 can be inclined relative to the seat cushion frame structure 14, said seat back frame structure 12 including a pair of side frames 20A,B each of which extends in a vertical direction of the vehicle, said seat 10 for the vehicle further comprising a through-hole 28 provided on a lower end portion of each of the pair of side frames 20A,B, a connecting rod 30 extending through each of the through-holes 28 so as to be rotatable about a horizontal direction, an electrical reclining motor 34 rotating said connecting rod 30 and provided along the one of side surfaces of the one of said pair of side frames 20A,B, and a reclining apparatus 16 provided on the other of the side surfaces of each of said pair of side frames 20A,B, a bolt through-hole 72 being provided on a non-rotational driven solid portion of said electrical reclining motor 34, a bolt 74 which fits into said bolt through-hole 72 is provided for fixedly bolting said electrical reclining motor 34 on said one of the side surfaces of the one of the pair of side frames 20A,B, said bolt 74 comprising a head portion 76 and a shank portion 78 with a circular cross-section, said shank portion 78 comprises an enlarged-diameter portion 82 on its end portion and a reduced-diameter portion 84 adjacent to the enlarged-diameter portion 82 with being concentric to each other.

A seat rotating device for a vehicle includes: a plate used to support a seat; and a pair of guide rails arranged side by side in a vehicle width direction and supporting the plate. The guide rails each have a fixed rail and a sliding member that supports the plate and is slidable along the fixed rail. The plate includes guides that guide each of the sliding members. The guides are configured such that the plate rotates while causing the sliding members to move in directions opposite to each other or the plate rotates based on movement of the sliding members in directions opposite to each other.
