Abstract:
An apparatus for sensing a forward position of a vehicle seat in a vehicle, said apparatus comprising:a permanent magnet located adjacent said forward position, said permanent magnet producing a magnetic field;a Hall effect device disposed in said magnetic field; anda first member mountable to the vehicle seat and movable with the vehicle seat, said first member being movable in a path which extends through said magnetic field to a predetermined forward position adjacent said Hall effect device and said permanent magnet, said first member being made of a ferromagnetic material;said permanent magnet creating a magnetic field of a first flux density acting on said Hall effect device to cause said Hall effect device to provide a first output signal when said first member is rearward of said predetermined forward position;said permanent magnet creating a magnetic field of a second flux density acting on said Hall effect device to cause said Hall effect device to provide a second output signal different than said first output signal when said first member is at or forward of said predetermined forward position.
