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.

The object of the invention is a latching device (1) for a backrest of a motor vehicle, with a locking mechanism (4) fundamentally comprising a catch (5) and at least one pawl, whereby the catch (5) is pivotable and is accommodated in the latching device (1) to accommodate a latch holder (6) and whereby the locking mechanism (4) can be transferred at least into a main ratchet position, and preferably into a pre-ratchet position and a main ratchet position, by means of the latch holder (6), a latch housing (10), whereby the latch housing (10) has at least an integrated recess (13, 14, 15) and whereby the recess (13, 14,15) is formed as a damping means (11) for the latch holder (6) in the main ratchet position and whereby the integrated damping means (11) has a cooperating section (17), whereby the cooperating section (17) has a supportive effect on the damping means (11).

An electrically operated backrest adjuster (1, 1) for a vehicle seat (3) includes a seat part (3.1) and a backrest (3.2) which is adjustable relative to the seat part (3.1). At least one of two fitting sidesof which each includes a fitting upper part (B1) mounted on the backrest and a fitting lower part (B2) mounted on the seat partincludes a fitting (2, 2) for adjusting the inclination of the backrest (3.2). The fitting (2, 2) is arranged between the fitting upper part (B1) and the fitting lower part (B2). The fitting sides are coupled to each other by a transmission rod (5). An electric drive unit (6, 6) is provided on one of the fitting sides. The drive unit is arranged on the outside of the associated fitting lower part (B2) is being coupled to the transmission rod (5) for driving same.

A vehicle seat reclining device is disclosed. An operation mechanism allows a second memory member to engage with and disengage from a first memory member, and locks and unlocks a lock member in conjunction with the engagement and disengagement. When the first memory member is in a predetermined rotational position relative to the second rotating member, the second memory member is inserted into an engagement slot provided in the first memory member, thereby restricting rotation of the first memory member relative to the second rotating member. The operation mechanism includes a link member that is linked to the second memory member inserted into a guide hole provided in a plate-shaped member. In the thickness direction of the plate-shaped member, the link member is arranged on the same side of the plate-shaped member as the first memory member.

Disclosed is a vehicle seat locking device including: a single latch having an engaging groove and first through third arm portions; a ratchet having a restraining portion engaging the first and second arm portions, restraining the latch in first and second latching positions respectively; and an engagement auxiliary lever having a first auxiliary arm portion abutting with a leg portion of a striker and a second auxiliary arm portion pivoting by this abutment. The latch pivots from an unlatching position to the first latching position by engaging its engaging groove with the leg portion entered a striker entering groove of a baseplate, and pivots to a second latching position by the pivot of the second auxiliary arm portion. The leg portion exits the engaging groove by the pivot of the latch to the second latching position to be clamped between the engagement auxiliary lever and the third arm portion.
