Function For Adaptive SEATBELT Force Limitation
In the event of a frontal collision where the front airbags and the front seat belt tensioners have deployed (8/33 and 8/34), the function for adaptive seatbelt force limiting may be activated. The supplemental restraint system module (SRS) also receives information from the seat position sensor (3/255, 3/256) about the positions of the passenger or driver's seats. The control module can determine whether the occupant is a large or small person. Using this information, the supplemental restraint system module (SRS) determines whether the adaptive seatbelt force limiter should be activated. If the adaptive seatbelt force limiter (8/128, 8/129) is activated, the supplemental restraint system module (SRS) transmits an activation signal, current pulse, to the adaptive seatbelt force limiter which reduces the force of the seatbelt on the chest.
