Abstract
A cylinder-piston type seat belt tensioning device comprises a broach pipe wherein a broach rod which is connected to a seat belt is disposed, a load limiting member connecting the broach rod to the piston, which is broken at a predetermined load, and locking means for locking the broach pipe in the cylinder when the load limiting member is broken. After the load limiting member is broken at a predetermined load, the broach rod returns while plastically deforming the broach pipe to absorb the kinetic energy of the occupant.
