Abstract:
A weight sensing apparatus for sensing a load applied to a vehicle seat, said apparatus comprising:a first mounting member mountable to a vehicle seat;a second mounting member mountable to a stationary body member of the vehicle and positioned opposite from and movable relative to said first mounting member;a pair of spaced apart and opposed guide elements connected between said first and second mounting members, said pair of guide elements guiding relative movement between said first and second mounting members;biasing means connected between said first and second mounting members for urging a spaced apart relationship between said first and second mounting members;a sensor element positioned between said first and second mounting members separate from said first and second guide elements, said sensor element having a variable reluctance condition functionally related to the relative spacing between said first and second mounting members, said sensor element providing a signal indicative of said reluctance condition and the load on the seat.
