Abstract

A belt clamping apparatus is provided for a seat belt system comprising a belt retractor and a device which is controlled by at least one acceleration sensor and serves to lock gears which are connected to the reel shaft of the belt retractor. The clamping apparatus comprises a clamping wedge, which is guided on a sliding surface that is fixed to a housing to move parallel to a back-pressure plate which is fixed to the housing, and together with the clamping wedge defines a gap for the passage of the belt, and an actuating member, which is movable by the locking device and displaces the clamping wedge to its clamping position. The actuating member is rotatably connected at one end to the housing and is pivoted at its other end to the clamping wedge, when the belt is being extracted further after the gears have been blocked by the actuating member in response to the movement of the reel shaft and imparts a translational movement to the clamping wedge. A spring element is provided between the clamping wedge and a stop which is fixed to the housing. The clamping wedge consists of one arm of a two-armed lever, the other arm of which constituted a spring abutment, and the spring-loaded …
