Retractor for a safety strap

摘要

In this retractor, the central assembly 4 comprises a metal strip 9 and a covering 10. In the regions of the latter forming bearing surfaces for rotatively mounting the assembly 4, plates 25a, 25b are provided which are only covered with a thin layer of the covering on their periphery. In this way defects in the roundness of the central assembly and irregularities in the winding and unwinding of the strap are avoided.
