Patent attributes
A magnetoresistive continuous seat track position sensor system to determine longitudinal movement of the seat along a length of a track is described. In one embodiment, the system comprises a magnetic array in a fixed position and having a width and a length along the seat track length. The array is equipped with a plurality of magnets arranged along the length of the array. The magnets have a polarity oriented at an angle θ relative to each other. The system further includes a magnetoresistive sensor in spaced apart close proximity to the magnetic array. In one embodiment, the magnetoresistive sensor is movable relative to the array. Movement of the sensor relative to the array creates a sensor signal indicative of the longitudinal position of the seat in the track to control auxiliary safety features.
