Coupling for safety belt coiler drive

摘要

The coupling and has at least one coupling element which disengages after the drive motion is complete. At least one coupling element (11, 13) is held in the engaged drive position over the duration of the drive motion via pressure produced from a pyrotechnical source. The coupling elements (11, 12, 13, 14) connected in the drive position are connected together by a clamping force produced pyrotechnically.
