Abstract
A belt retractor comprises a belt reel rotatably mounted in a frame, a locking mechanism for selective blocking of belt reel rotation and an activating mechanism for the locking mechanism with a control disk restrictedly rotatable with respect to the belt reel. The locking mechanism is activated by rotation of the control disk relative to the belt reel. A planetary gear is provided which includes a sun wheel connected to the belt reel for joint rotation, an annular gear secured to the frame and at least one planet wheel having an external toothing mating with the sun wheel and the annular gear. The planet wheel has at least one switching cam. A switching toggle is mounted to swivel between a normal position and a locking position. The switching toggle is moveable into the locking position by the switching cam of the planet wheel to inhibit the activating mechanism.
