Abstract
A seat position sensor including a generally u-shaped housing and a cover disposed on the housing for blocking entry contaminants into a shunt opening of the housing. A sensor including mounting wings that flex upon mounting is also provided, as is a sensor including an integral connector, and a two-piece sensor configuration. A PCB including a heat throttle trace and a heat sink region, and a supply voltage circuit for a Hall Effect sensor including a parallel connected varistor are also provided.
Claims9
A seat position sensor comprising:
- a generally u-shaped housing including first and second arms separated by a shunt opening;
- a magnet disposed in said first arm;
- a Hall Effect sensor disposed in said second arm and in a magnetic field generated by said magnet;
- and
- a cover disposed on said housing, said cover being spring biased in a first position wherein a portion of said cover obstructs said shunt opening and being movable against said spring bias to a second position for allowing entry of a shunt into said shunt opening.
A seat position sensor comprising:
- a generally u-shaped housing including first and second arms separated by a shunt opening;
- a magnet disposed in said first arm;
- a Hall Effect sensor disposed in said second arm and in a magnetic field generated by said magnet;
- and
- first and second mounting wings extending from opposite sides of said housing, each of said mounting wings including a mounting opening for receiving a fastener for fixing said housing to a mounting position;
- said mounting wings configured to flex inward against said mounting position upon fastening said housing to said mounting position.
A seat position sensor comprising:
- a generally u-shaped housing including first and second arms separated by a shunt opening;
- a magnet disposed in said first arm;
- a Hall Effect sensor disposed in said second arm and in a magnetic field generated by said magnet;
- and
- a connector affixed to said housing and including at least one terminal electrically connected to said hall effect sensor.
A printed circuit board comprising:
- a first conductive trace electrically to a second conductive trace through a heat throttle trace and a heat sink region.
A supply voltage circuit for a hall effect sensor comprising:
- at least one varistor connected in parallel with at least one capacitor and first and second input terminals of said hall effect sensor;
- and
- supply voltage input terminals for providing a supply voltage across said varistor.
A seat position sensor system comprising:
- a magnet coupled to a first seat rail;
- a sensor housing coupled to a second seat rail adjacent said magnet in at least one position of said seat;
- and
- a Hall Effect sensor disposed in said housing and in a magnetic field of said magnet in said at least one position.
