Abstract: A device for detecting the weight loaded on a vehicle seat with a sensor (22) and a spring body (24) that connects the vehicle seat to an underbody (18) of a corresponding motor vehicle and is connected, in one fastening area (e.g., 28), with a bottom rail (20) of the vehicle seat on the one hand and, in another fastening area (e.g., 26), to the underbody (18) of the corresponding motor vehicle on the other hand. One of the mounting areas is provided with a bore (38) through which a seat fastening screw (30) is engaged. The sensor (22) is provided with a travel sensor which is disposed parallel to the seat fastening screw (30) between the two fastening areas (26, 28) or to these rigidly connected parts (retaining plate 60 for example) and which measures the distance of these fastening areas (26, 28) parallel to the seat fastening screw (30).

Abstract: The vehicle seat has a seat pan and a seat back. The seat back is provided with a seat back carrier, a padding body arranged on the seat back carrier and a headrest fastened on the seat back carrier. An upper shoulder area of the padding body, which is adjacent to the headrest, is provided with a normal disposition to yield to the load of a passenger's back. This disposition to yield increases considerably in case of an acceleration due to an accident.

Abstract: The automobile seat occupant sensing unit has a sensor. The sensor consists of a sensor body and of at least one resistive strain gauge. The sensor body is provided with a main part and with at least one arm projecting from said main part. The main part is fitted with a fastening means for mounting the sensor and has a supporting surface. The at least one arm is elastically deformable in a direction transverse to the supporting surface, has a bearing area pointed toward a direction opposite the supporting surface and carries the at least one resistive strain gauge which is accommodated between the bearing area and the main part and which senses an elastic deformation of the at least one arm, said deformation being occasioned by the presence of an occupant in the vehicle seat.

Abstract: A seat, in particular a motor-vehicle seat, having a seat-adjusting mechanism is described. The seat-adjusting mechanism comprises a motor-driven spindle unit with a nut which has an inner profiled portion and a spindle which has an outer profiled portion. The spindle unit comprises a plurality of rollers which are arranged in planetary manner between the nut and the spindle and cooperate with the nut and the spindle. Each of the rollers has at least one outer profiled portion.
