A vehicle seat is provided. The vehicle seat comprises construction elements that are movable relative to one another and at least one force transmission element which transmits activation forces and/or stress forces that result from the use of the vehicle seat from one construction element to the other. The force transmission element by way of at least one joint is connected to both construction elements, and conjointly with the at least one joint is an integral component part of at least one of the two construction elements.

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.

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 brake-side clutch part includes an outer ring whose rotation is restricted and an output shaft from which rotation is output. The outer ring is provided with a slide gear that meshes with the output shaft when rotational torque is cut off and releases a meshing state with the output shaft when rotational torque is transmitted. The output shaft is provided with an inner gear that meshes with the slide gear so as to be slightly rotatable. An alignment part that aligns a phase of the inner gear with that of the slide gear when rotational torque is cut off, and a centering part that returns the inner gear to a neutral position with respect to the output shaft when rotational torque is transmitted are provided between the inner gear and the output shaft.

An adjustment device includes a housing in which a rotary element is rotatably mounted about a rotational axis, a locking device having a first locking element, connected in a rotationally fixed manner to the rotary element, and a second locking element arranged on the housing and which can be reversibly moved between a primary position in a locked situation, in which the locking elements have a form- and/or force-locking connection, and a secondary position without the connection. An adapter plate is rotates relative to the rotary element and the housing. An unlocking element cooperates with the adapter plate in an actuator region when the second locking element is transferred into the secondary position. The second locking element is shifted by an unlocking height in the unlocking region, and by a lifting height in the actuator region. The actuator region is arranged with the lifting height smaller than the unlocking height.

A moving and locking device for a vehicle seat includes: a lower frame mounted on a bottom surface of a seat cushion; a plurality of wheels disposed underneath the lower frame in such a manner that the plurality of wheels roll on a floor panel; and a vacuum adsorption device disposed inside the lower frame and configured to be adsorbed on the floor panel by vacuum force. The vehicle seat is configured to be moved to the desired position through the rolling motion of the plurality of wheels, and configured to be locked at the desired position through vacuum adsorption of the vacuum adsorption device on the floor panel.

An adjusting device (1) for a motor vehicle interior component includes a housing (3) in which a rotational element (2) is provided in a rotatable manner about a rotation axis (100). A first locking element (21) is rotationally fixed to the rotational element (2), and a second locking element (22) is provided on the housing (3). The locking elements are reversibly movable relative to each other from a locked situation, in which the locking elements (21, 22) interact with each other in a positively and/or non-positively engaged manner, into an adjustment situation, in which said positive and/or non-positive engagement is released. The adjusting device has an adapter plate (23) which is provided in a rotatable manner relative to the rotational element (2) and the housing (3) and at least temporarily drives a locking element (21, 22).

A swivel device for vehicle seats may rotate a seat mounted inside a vehicle at 180° or more and firmly fix the seat at a normal position before and after rotation. The swivel device includes: a base plate provided with a plurality of first locking members; a swivel plate disposed on the base plate to be rotated by a second motor; a rotary force transmission mechanism mounted on an output shaft of the second motor and the swivel plate to transmit a rotary force of the second motor to the swivel plate; an elevating plate provided with a plurality of second locking members separably coupled to the plurality of first locking members and formed on a lower surface of the elevating plate; and a first motor mounted on an upper surface of the elevating plate to transmit a rotary force to the lead screw.

A brake-side clutch part includes an outer ring whose rotation is restricted and an output shaft from which rotation is output. The outer ring is provided with a slide gear that meshes with the output shaft when rotational torque is cut off and releases a meshing state with the output shaft when rotational torque is transmitted. The output shaft is provided with an inner gear that meshes with the slide gear so as to be slightly rotatable. An alignment part that aligns a phase of the inner gear with that of the slide gear when rotational torque is cut off, and a centering part that returns the inner gear to a neutral position with respect to the output shaft when rotational torque is transmitted are provided between the inner gear and the output shaft.

A seat lifter device includes: an output shaft; a support unit that supports the output shaft; an input unit; a ratchet-type feed unit configured to transmit rotation of the input unit to the output shaft; a lock unit configured to lock rotation of the output shaft relative to the support unit; a friction generation unit configured to apply a friction force between a rotation member and the support unit in response to an operation of the input unit rotating in a direction in which the seat is lowered; and a slippage preventing unit. When the input unit rotates in the direction in which the seat is lowered and the output shaft rotates preceding to the feed unit against the friction force to slip, the slippage preventing unit is fitted to the support unit by an elastic force in response to slippage of the output shaft to stop the slippage.
