In recent years, it is standard for four-wheel vehicles to include equipment to protect the passengers such as a seat belt, an air bag and a child seat. In motorcycles, the time the time has arrived for the employment of techniques to contribute to the protection of a passenger upon the application of an impactive load to a vehicle body.
SUMMARY OF THE INVENTION
Accordingly, an object of the present invention is to provide a technique to contribute to the protection of a passenger upon the application of an impactive load to a vehicle body, especially upon the application of a shock applied to a side of motorcycle, or when the motorcycle is greatly lopsided.
To attain the above-described object, a vehicle air bag structure is provided for a vehicle having a passenger seat at the center of vehicle body frame. The structure includes side members guarding the left and right sides of a passenger sitting on the passenger seat and air bags disposed in the side members, so as to expand the air bags in case of necessity.
The structure including the side members guards the left and right sides of the passenger to reinforce the vehicle body frame and since the structure has the air bags in the side members it contributes to the protection of the passenger.
As a result, upon application of an impact load to the vehicle, the impact load applied to the passenger can be mitigated.
Further scope of applicability of the present invention will become apparent from the detailed description given hereinafter. However, it should be understood that the detailed description and specific examples, while indicating preferred embodiments of the invention, are given by way of illustration only, since various changes and modifications within the spirit and scope of the invention will become apparent to those skilled in the art from this detailed description.
