Abstract
A drive unit for winding and unwinding a transport cable for a safety belt includes a motor driven take-up roll positioned within a housing and rotatable about a winding axis. The take-up roll has a radially outwardly facing surface encircling the winding axis. A casing encloses the take-up roll and has a radially inwardly facing surface spaced outwardly from the radially outwardly facing surface. When the cable is wound into the housing it winds onto the radially outwardly facing surface and when it is unwound it contacts the radially inwardly facing surface on the casing. The radially inwardly facing surface is frusto-conical in the direction of the winding axis with the larger diameter portion of the surface located closer to the opening from the housing through which the cable passes. Adjacent its larger diameter end, the radially inwardly facing surface has a circumferentially and radially extending step for preventing bending or kinking of the cable.
