A bushing assembly includes a tube with an outer bearing surface, a metal part with an annular flange defining an opening and a plastic bushing with a bushing hub with an inner annular bushing contact surface and an axially extending metal part engagement surface. A friction torque setting connection is formed between the annular flange and the bushing hub and defines a rotational and axial connection between the annular flange and the bushing hub. The connection is configured to vary a radial force applied between the annular flange and the bushing hub with a deformation of bushing plastic material. This is to vary friction between the bushing contact surface and the tube outer bearing surface upon applying a torque to the plastic bushing, causing rotation and axial movement of the plastic bushing relative to the metal part, and causing the deformation of plastic material of the bushing hub.

A driving device in one aspect of the present disclosure includes an electric motor, a worm gear, a gear easing that stores the worm gear, a first fitting portion provided in the electric motor, a second fitting portion provided in the gear casing and fitting to the first fitting portion, and a restriction member that includes a pressure contact portion and a contact portion and restricts displacement of the worm gear along a rotation center axis thereof. The pressure contact portion is in pressure contact with one fitting portion out of the first fitting portion and the second fitting portion, and the contact portion is in contact with the other fitting portion.

A guide sleeve, for receiving a rod of a headrest, includes a sleeve body that has a rod receptacle for receiving the rod and an elastic region that is force-loaded in a direction of the rod receptacle in order to fix the rod in the rod receptacle. A spring element arranged on the outer contour of the sleeve body spring-loaded the elastic region. The spring element has a contact region adjacent to the elastic region, is configured as a clip that partially embraces the sleeve body and has a width in a sleeve body axial direction. The spring element includes a strip main body and the contact region is configured as a protuberance between two first bending points extending across the entire width of the main body. A vehicle seat for a motor vehicle has a backrest and a headrest, wherein the guide sleeve fastens the headrest to the backrest.

A vehicle seat includes a lifter device lifting/lowering a seat cushion. The lifter device includes a link member coupling a side frame and a riser to each other, and a clinching pin coupling the riser or the side frame and the link member to each other. The clinching pin includes a first portion located on the opposite side of the link member from the riser, a second portion located in a position corresponding to a hole of the link member, a third portion located in a position corresponding to a hole of the riser, and a fourth portion that is located on the opposite side of the riser from the link member. A surface of the second portion facing the riser has a portion adjacent to the third portion, and the portion is away from a surface of the riser facing the second portion.

A reduced-impact-and-recoil headrest that includes a ratchet mechanism, allowing components to incrementally translate with respect to each other. The reduced-impact-and-recoil headrest includes an exterior housing surface that is deformable, providing cushioning for a vehicle occupant's head. The headrest also includes an interior compartment within the housing, with the ratchet mechanism disposed within the interior compartment. The headrest is configured to decrease the force of a collision experienced by the occupant, thereby decreasing the likelihood and severity of traumatic brain injuries resulting from the occupant's head striking a stationary headrest. Instead, the reduced-impact-and-recoil headrest is configured to incrementally move with the occupant's head, providing an incremental cushion for the occupant's head. The ratchet mechanism also prevents the reduced-impact-and-recoil headrest from automatically translating back to its pre-impact position, thereby decreasing the occupant's risk of ligament tear and whiplash.

A vibration reduction device for a vehicle seat that can reduce forward/backward vibration when the vehicle is stopped with the engine idling. The vibration reduction device includes a weight mounted through an elastic body in the seat back or the headrest of the seat.

A seat slide adjuster suited to weight-saving has a structure in which two rows of engaged portions are provided at a predetermined interval in a direction orthogonal to a longitudinal direction of a locking plate that constitutes a locking mechanism, and the engaged portions engage with locking tooth parts on both sides of a lower rail during locking. Force that works between the locking plate and the lower rail acts on the locking tooth parts on both sides in a well-balanced manner and is not biased to either side. As a result, the durability of the components thereof can be improved. In addition, because two rows of hole portions in the locking plate engage, rattling of the locking plate is not likely to occur.

An assembly includes a first vehicle seat component, a second vehicle seat component that can pivot relative to the first vehicle seat component, a fastener to secure the first vehicle seat component and second first vehicle seat component together, and a spacer to absorb radial vibrations. The spacer includes a body and at least one flexible leaflet located between the body and the fastener to absorb axial vibrations. The body and the at least one leaflet are integral and monolithic to define a single component.

A motor vehicle seat floor slide rail includes a lower slide rail assembly (100), an upper slide rail assembly (200) and a gap elimination mechanism (230, 230), with a shaft-provided gap elimination cam (231L, 231R), on an upper slide rail longitudinal end, having a rotation center (232a) axis perpendicular to an upper rail longitudinal direction. A locking window face (117L, 117R) has an aluminum slide rail (110) longitudinal gap elimination face (113L, 113R). A rail locked state has a cam face (2311L, 2311R) in contact with the gap elimination face to eliminate a Y and Z direction gap. In a rail unlocked state, a locking mechanism (240) drives the gap elimination cam, such that the cam face loses contact with the gap elimination face. The gap elimination cam moves in linkage with the locking mechanism, reducing sliding friction, and having the advantage of low sliding assistance motive power.
