SEAT BELT LATCH SENSOR SYSTEM

A diagnosable seat belt latch system for use in a vehicle seat belt system provides a latch assembly incorporating a force sensitive sensor interposed between a latch housing and a pressure distribution bushing. A pivoting latch arm having a latch tab at one end for engaging an orifice of a seat belt buckle transfers a compressive load to the force distribution bushing and thereby to the force sensor. A signal processor diagnoses the force sensor to determine whether the seat belt is latched and generates a signal to a vehicle safety restraint system based on the determination.
