ABSTRACT:
The tightening means for safety belt restraining systems is equipped with a pyrotechnical piston/cylinder tightening drive which is inserted via fitting parts engaging the piston on the one hand and the cylinder on the other hand into the force flow path of the safety belt system. The cylinder is formed in a cylinder block which is guided displaceably parallel to the axis of the cylinder on a bodywork-fixed or vehicle-seat-fixed guide member. The piston is formed at the one end of a shear-stressable piston rod and in the readiness position of the tightening means is inserted with the piston rod into the cylinder. At its other end the piston rod is supported at the guide part. The release is by means of a vehicle-sensitive mechanical trigger mechanism. Instead of a return blocking mechanism is return brake is provided which reduces the stress peaks in the belt system.
