Patent ID: 10407176

Abstract:
In an illustrative embodiment, a seat is oriented at an oblique angle with respect to a centerline of an aircraft fuselage, the seat having an Aircraft Passenger Restraint System (APRS) with a pre-tensioner and integral retractable shoulder and seat belt webbing. In an illustrative example, the ARPS may be a three-point restraint to control a seat occupant's upper body, head and torso area. In some embodiments, the ARPS may further control the forces on the lower spine and torso. In some applications, the ARPS may operate to control the Head Injury Criteria (HIC) levels for the seat occupant's head, as well as the neck twist and upper spinal forces, to meet aircraft certification requirements imposed by the Federal Aviation Administration (FAA) and/or European Aviation Safety Agency (EASA). In response to a deceleration event, the ARPS may rapidly retract the belt webbing to substantially remove slack.
