Abstract
An inflatable restraint system for selectively restraining an occupant of a motorized vehicle is presented herein. The inflatable restraint system includes a bladder having forward and rearward panel portions. The bladder is attached to the vehicle instrument panel, and configured to transition from a non-expanded state, in which the rearward panel portion is substantially flush with respect to the instrument panel, to an expanded state, in which the rearward panel portion is extended into the passenger compartment distal from the instrument panel. An inflation device is operatively coupled to the bladder, and configured to selectively transition the bladder from the non-expanded state to the expanded state. One or more trajectory control arms are attached at one end to the bladder, and a second end to the vehicle. The trajectory control arms are configured to redirect the bladder along an upward, arcuate path when transitioning to the expanded state.
