Abstract
A seat belt system for restraining an occupant of a vehicle. The system includes a webbing and a pretensioner. A cable connects the webbing to the pretensioner. The pretensioner includes a housing, a gas generator, and an outer cylinder connected to the housing. A gas generator provides gases into a pressure chamber in the outer cylinder to drive a piston, an inner cylinder and the cable in a pretensioning direction. A sealing ring is located between the outer cylinder and inner cylinder. The sealing ring is configured to provide a seal to prevent the gases provided by the gas generator from passing. A deflector shield is located between the outer cylinder and the inner cylinder and closer to the pressure chamber than the sealing ring, wherein the deflector shield is configured to deflect the gases away from the sealing ring.
