Abstract
A seat belt tensioning device includes a cylinder and a piston, one fixed to a vehicle and the other to a seat belt. Means are provided for operating the cylinder, on impact, to retract a piston rod and tension the belt. The piston rod is provided with a load limiting portion to be broken when the tension load of the seat belt reaches a predetermined value. Means are provided for locking the piston in the cylinder when the load limiting portion is broken. A second rod connects the seat belt and the piston when the load limiting portion is broken. The second rod is provided with a plastically deformable portion in contact with the piston. When the tension force of the seat belt applied to the piston through the second rod increases, the plastically deformable portion is deformed to absorb the kinetic energy of the passenger.
