Abstract
A sensor unit for activating a blocking mechanism for a belt retractor of an occupant protection system for motor vehicles is provided. The sensor unit comprising a sensor element, a receptacle for displaceably mounting the sensor element so that it is deflected by the impact of forces acting transversally to weight, and a coupling mechanism coupling the sensor element with a blocking mechanism of a belt retractor in such a manner that the blocking mechanism is triggered by a deflection of the sensor element. The sensor element has a mean roughness depth of at least 0.1 μm at least in such areas of its surface by which the sensor element rests against a bearing surface of the receptacle.
