Restraint system including a resettable web tensioning device

An apparatus for tensioning an occupant restraint harness coupled to an occupant seat mountable in a motor vehicle, the occupant restraint harness including first and second lap webs securable about an occupant of the seat, the apparatus comprising:

• a web tensioning device configured to be attached to a rear side of the occupant seat, the web tensioning device having an actuated state and an unactuated state, and
• a mechanical movement converter configured to be attached to the rear side of the occupant seat and having an input operatively coupled to the web tensioning device, a first output coupled to the first lap web and a second output coupled to the second lap web, the mechanical movement converter responsive to a transition of the web tensioning device from the unactuated state to the actuated state to simultaneously apply tension to the first and second lap webs,
• wherein the web tensioning device is resettable from the actuated state to the unactuated state,
• and wherein the mechanical movement converter is responsive to a transition of the web tensioning device from the actuated state to the unactuated state to simultaneously release the tension applied to the first and second lap webs.
