    摘要: 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 arm holds the clamping wedge in engagement with the sliding surface which is fixed to the housing.

    摘要: In a safety-belt system comprising a winding and locking mechanism, a clamping device is provided which carries out a clamping of the safety-belt outside the reel winding, wherein this clamping effect is caused by a lifting motion of the winding and locking mechanism or of a part thereof and is fastened by suitable means so that the load-bearing clamping organ comes to engage with its entire clamping surface on the belt and the approach of the clamping surface to the belt is synchronized. According to the invention clamping readiness of the clamping organ is begun on every vehicle deceleration of more than 0.45 g and on every belt withdrawal acceleration of more than 1.5 g. The belt winder contains, apart from the driving spring and the winding shaft, only the sensor and control mechanism, and does not require any separate locking elements in order to cause preblocking.
