1. A non-contact position sensor comprising:
- a sensor assembly comprising at least one magnet disposed adjacent a magnetic field sensor; and
an activating member;
said magnetic field sensor providing a first output when said activating member is in a first position relative to said sensor assembly and a second output when said activating member is in a second position relative to said sensor assembly, said activating member not extending between said magnet and said magnetic field sensor in either of said first and said second position.

Abstract
A position sensor including a sensor assembly adapted to mount to a first rail of an automotive seat rail assembly. The sensor assembly includes a Hall device and a magnet. The assembly is mountable to the first rail to cause a first output of the Hall device when the first rail is in a first position relative to a second rail of the automotive seat rail assembly, and to cause a second output of the Hall device when the first rail is in a second position relative to the second rail.

18. A method of sensing vehicle seat position comprising:
-
providing a sensor assembly comprising at least one magnet and a Hall device;
mounting said sensor assembly to a first seat rail, said Hall device providing a first output when said sensor assembly is in a first position relative to a second seat rail and a second output when said sensor assembly is in a second position relative to said second seat rail, said second seat rail not extending between said at least one magnet and said Hall device in either of said first and second positions; and
determining a position of said seat in response to said output. - View Dependent Claims (19)
