  • Publication number: 20220161692
    Abstract: A longitudinal adjustment mechanism for a vehicle seat may have a first rail and a second rail. The rails may engage about one another to form an inner channel. A spindle nut may be connected to the second rail and a spindle operationally connected to the spindle nut may be arranged in the inner channel. On one end of the first rail, a transmission may be driven by a motor, which may interact with the spindle. The spindle may be screwed into an internal thread of a worm gear of the transmission, and the spindle may be conjointly connected by a fixing element to the worm gear. The fixing element may be arranged coaxially to a spindle axle of the spindle and may be pressed between a front end portion of the spindle and the worm gear. A vehicle seat having the longitudinal adjustment mechanism is also provided.

  • Patent number: 10668846
    Abstract: 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.
