ABSTRACT:
A seat belt tensioning device provided with a cylinder attached to the room of a vehicle, a piston slidably inserted into the cylinder, a rod of which one end is connected to the piston within the cylinder and of which the other end is connected to a seat belt outside of the cylinder through a joint member, and a piston operating means for moving the piston in one direction at an urgent time, is disclosed. The device is further provided with a piston operating energy absorbing member which is disposed between the joint member and the opposed end wall of the cylinder. When the piston moves to its limit stroke, the piston operating energy absorbing member is strongly sandwiched by the joint member and the end wall of the cylinder and is deformed by a predetermined load applied thereto to absorb the piston operating energy.
