TRW Automotive Holdings’ self-adaptive seatbelt load limiting technology is capable of automatically adapting according to occupant size. Operating without the need for sensors to gather data input and therefore offering a cost-effective solution, the self-adaptive load limiter (SALL) system has been designed to meet the needs of rear-seat occupants. Conventional load limiters for seatbelt systems are intended to provide protection for the full range of passenger weights, which is a standardized approach that requires that the system is adapted to fit larger passengers. TRW’s self-adaptive seatbelt load limiters can adjust the force level according to the amount of webbing that an occupant pulls out when he or she is buckled up. It is now in production on the Mercedes-Benz E-Class.
