An air bag mount device for mounting an air bag unit on a steering wheel device comprises an inflatuble air bag body in the air bag unit, an air bag cover provided in the air bag unit for covering the air bag body, a bag storing portion provided in the air bag unit for receiving the air bag body, and a control switch for controlling accessories mounted on a vehicle. The air bag cover is formed with a breakable split line, along which the air bag cover is split to form an opening through which the air bag body is inflated. The control switch is arranged on the air bag cover outside of opposite ends of the split line so as to be kept from being influenced by breaking of the air bag cover and the inflation of the air bag. |

DETAILED DESCRIPTION It is, therefore, an object of the present invention to provide an air bag mount device by which a control switch can be arranged on a steering wheel device conveniently.
It is a further object of the present invention to provide an air bag mount device on the steering wheel device without interfering with the control switch.
It is still another object of the present invention to provide an air bag mount device in which the air bag can be inflated without damaging the control switch in case of a collision.
The above and other objects of the invention can be accomplished by an air bag mount device for mounting an air bag unit on a steering wheel device comprising an air bag body in the air bag unit to be inflated, an air bag cover provided in the air bag unit for covering the air bag body, and a bag storing portion provided in the air bag unit for receiving the air bag body.
The air bag cover is formed with a breakable split line, by which the air bag cover is split, to form an opening for the inflating air bag body, and control switch means for controlling accessories mounted on a vehicle.
The control switch means is arranged on the air bag cover outside of opposite ends of the split line.
According to the above features of the present invention, where the air bag body is inflated, in case of a collision of the vehicle, the switch is not damaged, because the switch is located outside of the split line which forms the opening for the air bag body inflating.
In another aspect of the present invention, the control switch means is arranged on the air bag cover at opposite sides of the split line so that the split line can be elongated to facilitate the inflation of the air bag.
In another preferred embodiment, wall means is provided for partitioning the control switch means from the air bag body so that the switch means can be kept from being influenced by the breaking of the air bag cover and the inflating movement of the air bag.
The above and other features of the present invention will be apparent from the following descriptions making reference to the accompanying drawings
