Pretensioning aircrew restraint

Eaton’s next generation pretensioning aircrew restraint system (PARS), utilizing inertia reel technology, improves occupant safety and survivability by significantly reducing upper torso, head and neck flail during a crash event or hard landing. The system significantly reduces webbing slack immediately prior to a crash impact by sensing the impending impact and tensioning the restraint system. Functioning similar to air bag deployment, a crash recognition module sends a signal to actuate the PARS prior to impact, removing harness slack and quickly securing the aircrew upper torso. This pretensioning sequence limits forward motion of the upper torso, head and neck, significantly reducing the opportunity for head/torso contact with the cyclic stick or other cockpit structure.
