Abstract

A vehicle-sensitive sensor for a belt retractor for vehicle safety belt systems, comprises an inertia body displaceable in case of decelerations and accelerations of the sensor, and a two-armed lever. A first arm of the two-armed lever forms a coupling pawl, and a second arm of the two-armed lever is able to be engaged by the inertia body such that, in case of a displacement of the inertia body, the lever is pivoted so that the coupling pawl is directed into a clutch toothing.
