Abstract
A vehicle seat belt tension sensor for detecting the magnitude of tension in a seat belt when an occupant is in the seat. A limit structure is attached between a vehicle member and the seat belt. A sensor is attached to the limit structure to generate an electrical signal in response to the sensor being placed in tension. The electrical signal changes as a function of tension on the seat belt. The limit structure moves between a first position in which the sensor carries all of the seat belt tension and a second position in which the limit structure carries all of the seat belt tension.
