Abstract

A system for measuring seatbelt forces is used to control deployment of vehicle airbags. The system includes a seatbelt anchor assembly having a bracket mounted to a vehicle structure adjacent to a vehicle seat. A seatbelt mechanism has a belt portion that is looped through the bracket. The seatbelt is used to secure passengers or an infant car seat to the vehicle seat. A sensor is engaged with the anchor assembly and is used to measure the magnitude of forces exerted on the seatbelt by the passenger or car seat. The sensor generates a signal representative of the seatbelt forces, which is used to control deployment of the airbag.
