SEAT BELT TENSION-SENSING DEVICE AND METHOD OF DETERMINING AN AMOUNT OF TENSION BEING APPLIED TO A SEAT BELT WEBBING

摘要

A seat belt tension-sensing device and a method for determining the amount of tension applied to a seat belt webbing are provided. The seat belt tension-sensing device has a tension sensor configured to generate a signal in response to displacement of a flexible substrate that is indicative of an amount of tension being applied to the seat belt webbing.
