Abstract: A sensor system for detecting a movement of a first portion of a structure relative to a second portion of the structure is disclosed. The sensor system has a flexible retractable member having a first end pivotably attached to one of the first portion of the structure and the second portion of the structure and a second end driven by the other of the first portion of the structure and the second portion of the structure. The flexible retractable member is wound and unwound about the pivotal attachment upon relative movement of the first end with respect to the second end. Further, the flexible retractable member has at least one activation portion and at least one deactivation portion. The sensor system further includes a sensor for detecting the at least one activation portion and the at least one deactivation portion for determining at least one position of the second portion relative to the first portion of the structure.

Abstract: 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.
