ABSTRACT:
A rotary actuator-operated pretensioner comprises a gas generator and a rotary actuator that is driven in rotation by pressurized gas supplied by the gas generator and drives a belt take-up reel. Annular flange portions extend from the cylinder side walls into the operating chamber, the flange portions being coaxial with the axis of rotation of the rotor, and the rotor is supported by the cylinder for rotation by reception of the flange portions within end portions of the rotor body. An elastomer seal member is mounted on the side of the rotor vane portion that faces the pressure section of the operating chamber. The seal member has lip portions along its edges that are urged by gas pressure in the pressure section against the side walls and peripheral wall of the cylinder.
