Document Type and Number:
Japanese Patent JP4301476
Kind Code:
B2
Abstract:
A buckle is provided with a non-contact buckle switch to find an engagement condition with a tongue. When a lock member of the buckle is disposed in a locking position, a magnetic field produced by a magnet and applied to an IC Hall element differs from a case where the lock member is disposed in a non-locking position. The difference of the magnetic field is caused by the magnetic lock member moved close to the magnet and the IC Hall element, whereby an electrical current outputted by the electromotive force of the IC Hall element is changed. Thus, it is possible to determine that the lock pin is set in the locking position. The buckle switch is improved in durability and can operate more reliably.
