Abstract
A position sensor including: a reduction gear train having an input gear and an output gear. The input gear is configured for coupling to an output shaft of a drive motor for driving a vehicle seat on an associated seat track, and a magnet disposed on the output gear for rotation therewith. A Hall Effect sensor is disposed adjacent the magnet for providing a sensor output signal in response to rotation of the magnet. A lock out mechanism for a position sensor, a method of sensing the position of a vehicle seat, and a method of calibrating a vehicle seat position sensor are also provided.
