Abstract
Seat belt tension is determined by measuring the resistance of a flexible potentiometer which is deformed to produce a controlled change in resistance with increased belt tension. A seat belt mounting has a spring which allows limited extension of the seat belt in response to belt tension. A flexible potentiometer is mounted to the spring so that spring deformation produces a change in resistance which can be directly correlated to belt tension. Belt tension is input to an airbag deployment logic which may incorporate a seat position sensor, a weight-on-seat sensor and various other sensors which detect the existence, size and direction of any crash. The logic draws conclusions from the tension sensor in the seat belt and other sensors to determine if deployment of the front passenger airbag is likely to be advantageous to an occupant of the front passenger seat.
