Belt retractor for motor vehicle's seat belt has second energy absorption element installed between internal gear ring and frame, and gear ring can be mounted torsionally fixed on frame by means of slide

摘要

The belt retractor's second energy absorption element(26) is installed between an internally toothed gear ring(22) and frame(10) forming a friction connection. The gear ring can be mounted torsionally fixed on the frame by means of a slide(28). The resistance of the second energy absorption element is less than that of the first energy absorption element(18) located between the axial disc(16) and belt spool(12) and also forming a friction connection. A third energy absorption element(30) in the form of a torsion rod is installed between the belt spool and axial disc.
