ABSTRACT:
A belt pretensioner for a vehicular occupant restraint system comprises a piston/cylinder unit having a piston and a cylinder, a belt deflection member, a connecting part arranged between the piston and the belt deflection member and a ring-shaped seal. The cylinder has a cylinder wall with an end face and an opening in the end face through which the connecting part extends. The piston, the connecting part and the belt deflection member are displaced in a longitudinal direction upon actuation of the belt pretensioner to a tensioning path. The ring-shaped seal is arranged between the opening and the connecting part and uniformly engages the connecting part about its periphery so that any longitudinal displacement of the connecting part is counteracted by a force of more than 100 N as a result of which leakage gas flows are almost completely avoided.
