Abstract: A motor vehicle seat. The seat has a seat frame; a seat back pivotally mounted on the seat frame and which can be tilted forward out of its position of use and toward a seat surface of the seat frame; a longitudinal guide with which the seat frame is displaceable in the longitudinal direction of the seat in order to adjust the longitudinal position of the seat; a fixing device for fixing the seat frame in a previously adjusted longitudinal position of the seat, an actuating element for releasing the fixing device thereby enabling the seat frame to be displaced in the longitudinal direction of the seat, a coupling mechanism, which acts upon the actuating element and releases the fixing device when the seat back is tilted forward toward the seat surface, and a memory device by means of which the seat frame can be automatically held in a preset longitudinal position of the seat, which is defined as a memory position.

Abstract: A memory device, for a rail longitudinal guide for a motor vehicle seat, comprising two longitudinal guide rails displaceable towards each other, for the setting of the longitudinal seat position, a first memory module, which may be displaced along one of the two guide rails to set a memory position, a locking device for locking a set memory position, a second memory module, arranged on the second of the guide rails and a stop which, on reaching a relative position of the two guide rail corresponding to one of the memory positions, engages with a counter stop on the first memory module. The second memory module comprises a base body made from plastic, by which the latter is fixed to the second guide rail.

Abstract: An adjustable mechanism for a motor vehicle is used to adjust an adjustable element in a motor vehicle, especially a seating part. Said mechanism comprises a spindle nut comprising an axis, said spindle nut co-operating with a thread spindle and comprising external toothing on the external surface thereof which is in contact with an additional drive element. The external toothing of the spindle nut is formed by recesses in the external surface of the spindle nut which are inwardly turned in a radial manner, the teeth depths thereof diminishing in the direction of at least one axial end of the spindle nut.

Abstract: A longitudinal guide rail for a motor vehicle seat. The rail includes two elongated guide rails that engage with one another and are displaceable in relation to one another in the longitudinal direction of the rails, a retaining bracket for a seatbelt buckle, which is fastened to one of the two guide rails, a slot that is provided in one of the guide rails, through which a fixing section of the retaining bracket is guided into a space enclosed by the two guide rails and a fixing point, at which the fixing section of the retaining bracket is connected to one of the guide rails. The fixing section when viewed from the longitudinal direction of the rails, extends beyond the slot and the fixing point, also viewed from the longitudinal direction of the rails, is located at a distance from the slot.
