Sensor system for determining relative displacement of an object using an activation member

摘要

A sensor system for determining a relative position of a vehicle seat is disclosed. The sensor system has a sensing element and receiver element affixed to the vehicle seat. An enabler is disposed adjacent the vehicle floor. The enabler has at least one activation zone for causing the sensing element to communicate with the at least one receiver element and at least one deactivation zone is provided for preventing the sensing element from communicating with the at least one receiver element. The at least one activation zone defines at least one position of the vehicle seat and the at least one deactivation zone defines at least one other position of the vehicle seat.
