The invention relates, inter alia, to a belt retractor () for a safety belt device, with a belt reel () for winding up and unwinding the safety belt, a pretensioner drive () and a pyrotechnic tensioner drive (), wherein the pretensioner drive () has a force-flux-control element () which, in a deactivation position, interrupts the force flux between pretensioner drive () and belt reel (). It is provided that the pyrotechnic tensioner drive () has one or more drive elements () which, after activation of the pyrotechnic tensioner drive (), is or are set into motion, and, after activation of the pyrotechnic tensioner drive (), the force-flux-control element () is adjusted directly or indirectly by the drive element () or&#x2014;in the case of a plurality of drive elements ()&#x2014;by at least one of the drive elements () of the pyrotechnic tensioner drive () into the deactivation position.

Belt retractor for a safety belt device

A seat belt retractor for a safety belt including a seat belt spindle for winding up and unwinding the safety belt and a tensioning drive. The seat belt spindle includes a gas generator, a drive wheel and a supply pipe which connects the gas generator and the drive wheel. A plurality of thrust members are present in the supply pipe which, after triggering the gas generator, are accelerated and indirectly or directly drive the drive wheel for winding up the safety belt. An inertia coupling is arranged between the drive wheel and the seat belt spindle. The inertia coupling comprises coupling elements which, during an acceleration of the drive wheel, pivot outward and are directly or indirectly coupled to the seat belt spindle.
