Abstract: The invention relates to a force deflection device (1) for adapting a lap strap to enhance the comfort of the wearer and optimize the introduction of forces for use by pregnant women and the overweight, comprising a force deflection strap (6) with a first end, which is to be attached to the lap strap, and a second end, which is to be passed through the gap between the seat cushion and the seat back and to be attached to the seat. This second end of the force deflection strap (6) has attached to it a fixing element (2), which is preferably plate-shaped, that cannot pass through said gap in a transverse position relative to the seat. The fixing element (2) can be attached to the rear side of the seat back by means of a hook and loop fastener (3). At its first end, the force deflection strap (6) preferably has a hook (4) and eyes (5) that can be hooked into the latter, allowing it to be looped around the lap strap.

Abstract: The invention is based on a radial piston pump (1) with a pump body (2), in which pump body (2) are placed pistons (4), and cylinders (5) arrayed radial to a cam (14) and the pistons (4) upon an inward thrust suck in fluid by means of suction side intakes (17) and upon an outward thrust, the pistons (4) impel fluid through pressure openings (7) in the outer end walls (6) of the cylinder (5) into a plenum (10). It is proposed, that in the base of the cylinders (4) respectively a connection boring (32) is made to the cam (14), which connection boring (32) is controlled by a relief valve (18). Upon the exceeding of its opening pressure the relief valve (18) opens and pressure peaks in the cylinder (5) can be diminished by means of said connection boring. At the same time, a pressure buffer between the base of the piston (4) and the bearing shell (16) is formed.

The proposal is made, that a stress relieving zone (27) of a piston-cylinder unit (4, 5) be connected to the pressure zone (5, 7, 26) of a neighboring piston-cylinder unit (4, 5).
