A magnetoresistive continuous seat track position sensor system to determine longitudinal movement of a seat 10 along a length of seat track 20 is described. In one embodiment, the system comprises a magnetic array 34 in a fixed position having a plurality of magnets 58, 60, 62, 64, 66, 68, 70, 72, 74, 76, 78, 80, 82 and 84 arranged along the length of the magnetic array 34. The magnets 58, 60, 62, 64, 66, 68, 70, 72, 74, 76, 78, 80, 82 and 84 have a polarity oriented at an angle relative to each other. The system further includes a magnetoresistive sensor 36 in spaced apart close proximity to the magnetic array 34, movement of the magnetoresistive sensor 36 relative to the magnetic array 34 creating a sensor output signal indicative of the longitudinal position of the seat 10 that can be used to control auxiliary safety devices 54, 56. |
