A seat adjuster having a fixed part (12), a drive element (26), an output element (22, 24), a clamping body coupling arrangement (16) by means of which a back and forth movement of the drive element (22, 24) out of a neutral position and back into the neutral position is converted into a continued movement of the output element (22, 24) in a uniform direction of rotation, and a releasable locking device for locking the output element (22) in a form-fitting manner on the fixed part (12), characterized in that the locking device is formed by a locking ring (74) which is axially displaceable between a locking position, in which it is non-rotatably coupled to the output element (22), and a release position, and cam surfaces (82, 84) are formed on the locking ring (74) and the drive element (26), which cam surfaces are complementary to one another and translate a rotation of the drive element (26) away from the neutral position into an axial movement of the locking ring (74) into the released position.

A clutch unit that is used for a vehicle seat includes: a housing, which accommodates at least one of a input-side clutch and a output-side clutch, a first engaging portion, which is rotatable integrally with an output shaft member, and a lock member, which is able to be shifted between a locked state, in which the rotation of the output shaft member relative to the housing is suppressed by the lock member being locked to the first engaging portion, and an unlocked state, in which the rotation of the output shaft member relative to the housing is allowed by releasing the engaging with the first engaging portion, wherein when the lock member is shifted from the locked state to the unlocked state, the lock member is elastically deformed to release the engagement of the lock member and the first engaging portion.

A brake device for a motor vehicle seat is composed of a brake assembly, a tooth assembly, and a lever assembly. The brake assembly includes a housing, a pinion shaft, a braking component, and a drive wheel that are structured to be self-held in an assembled state by mechanical interaction thereamong. The tooth assembly includes a holder plate and a tooth plate that are structured to be self-held in an assembled state by mechanical interaction therebetween. The lever assembly includes an input lever, a cover, a coil spring, and a lever bracket that are structured to be self-held in an assembled state by mechanical interaction thereamong. The brake assembly, the tooth assembly, and the lever assembly are arranged and assembled together in an axial direction.

A lifter device including: an input member configured to be rotated about a rotation shaft in synchronization with an operation handle and to input an operation force of the operation handle to a rotation drive mechanism and a lock mechanism; and a fixing member slidably fixing the input member to a support member rotatably supporting the rotation shaft.

An entry/exit support structure of a vehicle seat has: a side support portion that is provided in a seat transverse direction of a seat cushion, and that is displaced in a seat vertical direction; a seat sliding mechanism that supports the seat cushion to slide in a seat front-rear direction, and that has a locking device restricting sliding of the seat cushion in the seat front-rear direction; and a side support portion restricting mechanism having a release operation portion. In a state in which the release operation portion is positioned at a lock position, displacement of the side support portion in the seat vertical direction is restricted. In a state in which the release operation portion is positioned at a release position, displacement of the side support portion in the seat vertical direction is permitted and sliding of the seat cushion in the seat front-rear direction is permitted.

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.

The present disclosure relates to a stepless brake device of a vehicle seat. The coupling piece formed on the plate cover disposed on the outermost rear surface is caulked and coupled to the housing cover disposed on the outermost front side. Therefore, the components are firmly coupled, and no axial gap occurs between the components. Also, tolerance accumulation of the components does not occur, so that the tilt of the roller is reduced, and thus, collision noise of the roller during the release operation is prevented.

A suspension seat, including: a lower side member that forms a vehicle lower side of a suspension; an upper side member that forms a vehicle upper side of the suspension, and that is configured to support a vehicle seat body from the vehicle lower side; a suspension link mechanism that includes a vehicle lower side portion coupled to the lower side member and a vehicle upper side portion coupled to the upper side member, and that undergoes displacement so as to displace the upper side member along a vehicle vertical direction; a linear displacement section that is provided at the suspension link mechanism and is configured to undergo linear displacement in conjunction with displacement of the suspension link mechanism; and a locking mechanism that immobilizes the linear displacement section so as to immobilize displacement of the suspension link mechanism.

The invention relates to a vehicle seat crash securing device (1) used for a vehicle seat of a motorized vehicle. The vehicle seat crash securing device (1) comprises a locking device for locking a height of a seat cushion frame. An actuator (3) is actuated in the case of a crash for tightening a belt rope (5). A blocking element in a blocking position holds a locking element of the locking device in an unlocked position. In a releasing position, the blocking element releases the locking element. The locking element is biased by a spring element into the locked position. The blocking element can be moved by a friction force generated by the actuator (3) from the blocking position into the releasing position. Preferably, the friction force is generated by a follower (8) (e.g. a friction wheel (9)), the follower (8) being pressed against the belt rope (5). The movement of the follower (8) is coupled to the movement of the blocking element.

A lifter device, wherein a pawl operating member is configured to be rotatable with respect to a rotation shaft so as to rotate in accordance with an operation of an operation handle and includes a first projection protrudingly formed on its outer peripheral side for rotational alignment, wherein a support member includes a second projection which is protrudingly formed so as to face the first projection and which serves as a reference position of a pawl operating member in a rotational direction, and wherein, in a state where the operation handle is not operated, a second spring is configured to bias the first projection so as to overlap with the second projection in the rotational direction of the pawl operating member.
