Abstract: A longitudinal adjusting device for the motorized longitudinal adjustment of a motor vehicle seat may have a first rail and a second rail. The device may also have a spindle gearbox, a spindle cooperating with the spindle gearbox for the longitudinal adjustment, and a mount for receiving the spindle gearbox. The spindle gearbox may be at least partly held in the inner channel so as to be fixed relative to the first rail. Laterally projecting protrusions of the holding legs of the mount, which legs may be each arranged in front of and behind the spindle gearbox in the longitudinal direction, engage through lateral openings in the first rail. An abutment device having a contact section may be arranged in the region of the lateral openings. The contact section contacts the holding leg arranged in the particular opening. A vehicle seat with the device is also provided.

Abstract: A vehicle seat having a seat part, a backrest, a kinematics system for transferring the vehicle seat from a use position into an entry position and back, a drive apparatus for driving the kinematics system, and a coupling apparatus for coupling the drive apparatus to the kinematics system. The coupling apparatus has a pawl and a counter-element. The pawl and the counter-element are locked to one another in order to couple the drive apparatus to the kinematics system, wherein the pawl is released from the counter-element by an actuation of the coupling apparatus, resulting in the drive apparatus being decoupled from the kinematics system. The pawl is configured as a bracing pawl, and the pawl and the counter-element are locked to one another beyond a self-locking action.

Abstract: A vehicle seat may have an upholstered section and at least one cover for capping a through opening in the upholstered section. The cover may have a support, a trim and a cap. A method for fitting the cover may have at least the following steps: fitting the trim and the cap to form a preassembled subassembly, fitting the support on a seat frame of the vehicle seat, positioning an upholstered section on the seat frame, and inserting the subassembly through a through opening in the upholstered section into the support.
