Abstract: A system for tripping a restraint device includes a trip circuit disposed centrally in a vehicle and an ignition device disposed noncentrally. The ignition device communicates with the trip circuit over a data line. A protection device is disposed in the ignition device. The protection device is preferably constructed as a mechanical switch which is dependent on acceleration. The likelihood that interference variables will simultaneously affect both the trip circuit and the protection device is reduced because of the spatial separation of the protection device and the trip circuit.

Abstract: The invention relates to a double pump consisting of a radial piston pump (1) and a vane-cell pump (2). The double pump is to be simplified in such a way that its over-all length is reduced and there is only one casing separation. The radial piston pump (1) has a ring insert with a molded face plate (8) fitted in an aperture (5) of the casing (4) to seal a pump set (20, 21, 22) of the vane-cell pump (1). One frontal surface (23) of the face plate, belonging to the ring insert (8), together with the casing (1) forms a dividing seam between the two pumps (1 and 2). Thus, only one annular seal (35) is needed to seal the dividing seam. The ring insert (8) with a concentric bore (36) also serves as a shaft (6) bearing and as an axial stop face (38) in the region of the eccentric (12).
