AIR BAG DEVICE WITH HORN SWITCH, AND STEERING WHEEL WITH AIR BAG

摘要

PROBLEM TO BE SOLVED: To provide an air bag formed integrally with a simple horn switch with excellent operability. SOLUTION: A bag cover 4 is energized, to a front side, by a leaf spring 8 locked to a retainer 3 rotatably in longitudinal direction and disposed between the rear surface side of the bag cover 4 and the retainer 3, a horn switch support plate 3b is projectedly formed on the outside of the outer peripheral part of the retainer 3, and a leaf spring holding member 10 formed of an electric insulator and holding the end part of the leaf spring 8 in electrically insulated state is installed on the horn switch support plate 3b. A horn switch 9 comprises a movable contact 9a formed at the tip part of the leaf spring 8, a fixed contact 9b formed at the position of the horn switch supporting plate 3b in correspondence with the movable contact and earthed to a vehicle body through the retainer 3, and wiring 12 connected to the rear end part of the leaf spring 8 and connected to the positive pole side of a horn power. Thus the movable contact 9a can be brought into contact with the fixed contact 9b by pressingly lower the bag cover 4 against the spring force of the leaf spring 8 to form a horn circuit so as to sound a horn.
