Abstract
A sliding seat position detection system includes a sensor provided on a seat that can slide on a floor of a vehicle, and a magnetic shielding member provided on the floor. The detection system detects that the seat is at a front end position when the shielding member provides a shield between a permanent magnet and a magnetism detection part of the sensor. A non-magnetic cover member is attached to the shielding member. When the seat is at a position other than the front end position, the cover member is positioned between the permanent magnet and the magnetism detection part of the sensor, thereby preventing erroneous detection due to magnetic foreign matter and other magnetic substances caught in or attached to the sensor.
