Abstract:
1. A magnetoresistive continuous seat track position sensor system to determine longitudinal position of the seat along a length of a track; comprising: a magnetic array in a fixed position and having a width and a length along said seat track length; said array equipped with a plurality of magnets arranged along the length of said array, the plurality of magnets including three or more magnets; each said magnet having a polarity oriented at an angle θ relative to each other; whereby the polarity of each of the magnets has an orientation relative to a line segment defined by said length, the orientation relative to the line segment being different for each magnet than the orientation to the line segment for any of the other magnets; and a magnetoresistive sensor in spaced apart close proximity to said magnetic array; said magnetoresistive sensor movable relative to said array; movement of the sensor relative to the array creates a sensor signal indicative of the longitudinal position of said seat in said track to control auxiliary safety features.
