Abstract

A sensor for use in a safety belt retractor equipped with a reel blocking mechanism performs a vehicle-sensitive triggering of said blocking mechanism. A sensor housing (30) has a trough in which a sensor ball (34) is received and a sensor lever which is pivotally mounted on said sensor housing (30). The lever has a cap which bears on said ball. The cap and the trough each have at least one portion connected via at least one elongated web (40) to said sensor housing (30). Thus, these cap and trough portions are elastically deflectable under the action of vibrations transmitted to the ball (34) in use of the sensor to dampen noise generated by the sensor parts.
