Abstract: A seat may have a seat longitudinal adjustment device having two rail pairs. The rail pairs may each have a lower rail and an upper rail. A contacting device is provided at least for electrically connecting a drive unit and a number of seat components to at least one control unit and to an electrical power supply unit. The contacting device may have at least one plug having a number of contact pins and/or contact elements, and a socket having a number of corresponding mating contact elements. When the plug is inserted into the socket, at least the electrical connection is established between the electrical power supply unit and the at least one control unit and the drive unit for the seat longitudinal adjustment device and the seat components. The contacting device may have at least one positioning element and/or one short-circuit element.

Abstract: A cable cassette for a seat longitudinal adjustment apparatus may have at least a housing and two rotatably mounted deflecting rollers. One of the deflecting rollers may be held such that it is guided for longitudinal movement in the housing relative to the other, stationary deflecting roller. A first free end of the connecting cable of the cable bundle is held in a fixed position via a first cassette outlet and the connecting cable or the cable bundle is guided and deflected around the movable deflecting roller and led from the movable deflecting roller to the other, stationary deflecting roller and is deflected around said stationary deflecting roller. A second free end of the connecting cable or of the cable bundle is movably mounted. A seat longitudinal adjustment apparatus may have the cable cassette.

Abstract: A plug-in unit for a plug-in connector, the plug-in unit may have a housing, a plug with a number of plug-in contacts, a triggering unit and a drive unit. The triggering unit unblocking or releasing the drive unit upon triggering, with the result that the plug, driven by the drive unit, is movable relative to the housing from a rest position into a plug-in position. The plug-in connector may be used with a seat arrangement and a vehicle.

Abstract: A fastening arrangement of a seat on a rail arrangement may have a modular construction and may have one lock module for releasably arresting the fastening arrangement on the rail arrangement. The fastening arrangement may also have one lock unlocking module for unlocking the lock module. The fastening arrangement may also have one rail unlocking module.

Abstract: An adjustment device for a vehicle seat, by which the inclination angle of the backrest of the vehicle seat can be adjusted relative to the seating part, has an adjustment range that is adjustable by removable stops.
