Airbag system
First Claim
1. An airbag system comprising:
- an airbag unit for storing a folded airbag;
an inflator unit for storing an inflator for generating gas for inflating the airbag;
the airbag unit and the inflator unit being connected to each other via a gas supply member; and
an inflator case for storing and protecting the inflator hermetically, said inflator case being divided into a pair of two case halves along a flat parting plane,the gas supply member being an interior portion of a main frame member of a vehicle, the main frame member extending rearwardly from a head pipe,wherein the inflator case is disposed in a space surrounded by the main frame member, a seat rail and a lower pipe of the vehicle and connected to a rearward portion of the main frame member, and the airbag unit is disposed on and connected to an upper surface of the main frame member in the vicinity of the head pipe,wherein an interior portion of the main frame member is used as a gas passage for introducing gas generated by the inflator into the airbag unit, andwherein an L-shaped gas guiding plate is provided in the main frame member near the airbag to deflect gas flow to the airbag.

Abstract
An inflator unit provided on a main frame of a motorcycle is provided with an inflator case having an inflator stored therein. Gas generated by the inflator flows through the interior of the main frame and is supplied to the airbag. The inflator case includes the left and right case halves divided along the parting plane and joined with each other by two bolts and the internal space thereof narrows towards an exit opening in the funnel shape. The axis Li of the inflator is shifted to the side opposite from the exit opening with respect to the axis Lc of the inflator case. A main frame may be formed with an atmosphere communication hole for communicating the interior of the main frame with the atmosphere at the position near the inflator case so that the atmosphere is introduced through the atmosphere communication port into the interior of the main frame by the negative pressure generated when gas flows from the inflator to the airbag. Thus, a large-volume airbag can be deployed by a small-capacity inflator.

12. An airbag system comprising:
-
an airbag unit for storing a folded airbag; an inflator for generating gas for inflating the airbag; and the airbag unit and the inflator being disposed separately; wherein an interior portion of a pipe member constituting a part of a vehicle body frame (F) is used as a gas passage for introducing gas generated by the inflator into the airbag unit, wherein the inflator is disposed in an inflator storage section eccentrically and an exit opening for allowing gas to exit from the inflator storage section towards the pipe member is provided on a side far from the inflator. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19)
