International ClassB60R 022/42Foreign Application Priority Data1987-05-22 DEAbstractA clamping device for the seat belt of a motor vehicle has a housing which is provided with a tapered passage bounded by mutually inclined first and second surfaces. The belt extends from a take-up reel, which automatically locks in response to high deceleration, into and through the passage adjacent to the first surface. A wedge-shaped clamping element is disposed in the housing between the belt and the second surface, and the side of the clamping element which faces the belt is provided with sawteeth. The clamping element is slidable along the second surface between a clamping position in which the toothed side thereof presses the belt against the first surface and a released position in which the clamping element is out of contact with the belt. The clamping element is connected with the take-up reel in such a manner that it moves from the released position to the clamping position in response to locking of the take-up reel. The first and second surfaces, the toothed side of the clamping element and the side of the clamping element adjacent to the second surface are all coated with an antifriction layer.Field of SearchBODY OR OCCUPANT RESTRAINT OR CONFINEMENTSafety belt or harness; e.g., lap belt or shoulder harness Having means to lock belt against further extension when in its occupant-restraining position Having means to lock belt against further extension when in its occupant-restraining position Shoulder belt or harness | |
