ABSTRACT:
An apparatus for tensioning a safety belt in response to applied gas pressure makes use of hollow winding roller attached to the safety belt and having a selected contour on its inner surface. A piston in a working cylinder is located coaxially adjacent to the roller. When the piston is displaced by the application of gas pressure it projects into the roller and engages the contouring on the inside surface of the roller to cause the roller to rotate in the direction of belt tightening.
