Abstract
A battery disconnection system (10) for a motor vehicle comprising a rod (12) having a longitudinal axis (A), an external threaded surface (14) extending from one end and a cylindrical member (16) extending coaxially with the rod (12), from the other end. Reversible drive means (20,22,24) engage the threaded surface (14). A first annular member (30) coaxial and in sliding contact with the cylindrical member (16). A second annular member (32) coaxial and in sliding contact with the cylidrical member (16). Either annular member being connectable with a motor vehicle battery. The other annular member being connectable with a starter motor and/or a generator (38) of a motor vehicle. The reversible drive means (20,22,24) moves the rod (12) in a longitudinal direction (X) between a first position in which the cylindrical member (16) engages and electrically connects the annular members (30,32) for normal operation of the motor vehicle, and a second position in which the cylindrical member (16) is disengaged from one of the annular members (30,32) during sensed adverse conditions such as a vehicle crash.
