Abstract:
1. A safety restraint system for a motorized vehicle having a passenger compartment with a safety belt assembly mounted therein, the safety belt assembly having a belt webbing, the safety restraint system comprising: a tubular member defining an elongate channel; a piston member operatively disposed inside said channel to selectively translate from an undeployed position to a deployed position; a linking member operatively connecting the belt webbing to said piston member such that translation of said piston member increases tension of the belt webbing; a cushion member operable to selectively transition from a non-expanded state to an expanded state, wherein at least a portion of said cushion member is wrapped around said tubular member; and an inflation device in fluid communication with both said cushion member and said tubular member, wherein activation of said inflation device operates to transition said cushion member from said non-expanded state, in which said cushion is generally stowed, to said expanded state, in which said cushion is deployed into the vehicle passenger compartment, and translate said piston member from said undeployed position to said deployed position.
