Apparatus for sensing position of a vehicle seat
First Claim
1. An apparatus for sensing whether a rail member of a vehicle seat is located in a reference position relative to a seat bracket of the vehicle seat, the apparatus comprising:
- a magnetic sensor for generating a magnetic field and for sensing a flux density of the magnetic field; and
a cover for enclosing the magnetic sensor, the cover, when in a first position, forming a zone for preventing the flux density from increasing above a threshold level, the cover being moved into a second position when the rail member is located in the reference position relative to the seat bracket, in the second position the flux density increasing above the threshold level.

Abstract
An apparatus (10) for sensing when a rail member (48) of a vehicle seat (12) is located in a reference position relative to a seat bracket (30) of the vehicle seat (12) comprises a magnetic sensor (76) for generating a magnetic field and for sensing a flux density of the magnetic field. The apparatus (10) further comprises a cover (86) for enclosing the magnetic sensor (76). The cover (86), when in a first position, forms a zone for preventing the flux density from increasing above a threshold level. The cover (86) is moved into a second position when the rail member (48) is located in the reference position relative to the seat bracket (30). In the second position, the flux density is increased above the threshold level.
