Document Type and Number:
Japanese Patent JP3073710
Kind Code:
B2
Abstract:
A motor-vehicle door-latch system has a key cylinder pivotal about an axis from a center starting position into a pair of opposite end positions flanking the center position, a key insertable into the cylinder only in the starting position thereof, a latch operable by the cylinder on displacement of same into one of the end positions, and an arcuate magnet pivotal about the axis, polarized generally parallel to the axis, and coupled to the cylinder for joint angular movement therewith. A pair of hall-effect sensors are juxtaposed with the magnet and positioned such that in the central position the magnet is closely juxtaposed with both sensors, in the one end position the magnet is closely juxtaposed with one of the sensors and is spaced from the other of the sensors, and in the other end position the magnet is closely juxtaposed with the other sensor and is spaced from the one sensor. A lock system connected to the sensors has an antitheft mode initiated by the sensors on displacement of the cylinder into the other of the end positions.
