A vehicle-sensitive sensor for a self-locking belt retractor, including a carrier part (), a locking lever () including an engagement point (), and a sensor mass () coupled to the locking lever (), disposed as standing upright on a supporting face () of the carrier part () and tiltable with respect to the carrier part () The sensor mass () includes a sensor part (), made of a first material, resting on the supporting face (), and of a mass part (), made of a second material, connected to the sensor part (), disposed above the supporting face (), wherein the first material forming the sensor part () has a lower density and a lesser hardness than the second material forming the mass part ().

Vehicle-sensitive sensor with multi-part sensor mass

A self-locking belt retractor has a vehicle-sensitive controlled blocking system in which a mass () moves a locking lever () engaged in the toothing () of a controlled disk. The sensor mass () is fitted in a holder part () on a support surface () that can be tilted in case of vehicle accelerations, the locking lever () on the end () facing away from the engaging tip () being connected to the sensor mass () in a form-fitting manner and forming a support (). A form fit occurs in an extension () of the sensor mass () which protrudes through a hole () in the contact surface () of the holder part (). A projection () projecting into a hole () is provided at the border of the hole () facing the locking lever () that is contacted by the locking lever () in case of a deflection.

Self-locking belt retractor

An inflatable safety belt has a belt webbing () with at least two belt webbing layers () put on top of each other and forming a hollow space in between, a gas generator () having a flow connection to the hollow space, and an anchor fitting () for fastening the belt webbing () and the gas generator () to a motor vehicle. The ends of the belt webbing layers () are connected to the anchor fitting () in such a way that the flow connection to the gas generator () is free of tensile forces.
