Ford and Key Safety Systems worked together to commercialize a new visible safety device for rear seat vehicle occupants. Sharing some patents the Ford and Key teams created a breakthrough by routing the airbag gas through the seat buckle and tongue into the torso portion of the safety belt. This is significant improvement in safety for rear belted passengers, especially children. Commercializing this innovation required collaboration on the design, manufacturing and testing of a new buckle design; new tubular webbing and a one-piece-woven cushion and fold air bag design both developed by KSS; and the Cold Gas Deflator. While Key is the primary developer of this innovation the teams collaborated throughout the process.
