Head protecting airbag device
First Claim
1. A head protecting airbag device comprising an airbag folded and housed above the upper edge of a window inside of a vehicle and expanded while being extended to cover the inner side of said window when it admits an inflating gas, wherein said airbag includes:
- a body portion for covering the inner side of a side window positioned on the side face of the vehicle; and
a sheet-shaped flexible extension portion arranged on at least the front of said body portion and extending on the inner side generally perpendicular to said side window so that it can be arranged in front of a passenger when said airbag expands, wherein said body portion fixes the upper edge upon completion of the expansion on the body side while allowing the lower edge upon completion of the expansion to move generally perpendicular to said side window, and wherein said extension portion is fixed at its leading end, removed from said body portion, on the vehicle body and housed in a roof portion over the front side of the passenger such that it can protrude downward along with said body portion housed above the upper edge of said side window.

Abstract
A head protecting airbag device comprising an airbag folded and housed above the upper edge of a window inside of a vehicle and expanded while being extended to cover the inner side of the window when it admits an inflating gas. The airbag includes a body portion and an extension portion. The body portion covers the inner side of a side window positioned on the side face of the vehicle. The extension portion is arranged on at least the front end of the body portion, and extends on the inner side generally perpendicular to the side window. Moreover, the extension portion is formed into a sheet shape having flexibility such that it can be arranged in front of a passenger upon completion of the expansion of the airbag. Moreover, the body portion is fixed at its upper edge upon completion of the expansion on the body side while allowing the lower edge upon completion of the expansion to move generally perpendicular to the side window. The extension portion is fixed at its leading end removed from the body portion to the vehicle body and is housed in a roof portion over the portion of the cabin in front of the passenger such that it can protrude downward along with the body portion housed above the upper edge of the side window. In this head protecting airbag device, the body portion of the airbag can be smoothly arranged between the passenger and the side window by moving its lower edge. Moreover, the extension portion can protect the passenger moving forward.

6. A head protecting airbag device comprising an airbag folded and housed above the upper edge of a window inside of a vehicle and expanded while being extended to cover the inner side of said window when it admits an inflating gas,
wherein said airbag includes: -
a body portion for covering the inner side of a side window positioned on the side face of the vehicle; and
a sheet-shaped flexible extension portion arranged on at least one longitudinal end of said body portion, extending on the inner side generally perpendicular to said side window, and fixing its leading end removed from said body portion on the vehicle body, wherein said body portion is fixed at its upper edge upon completion of the expansion on the vehicle body while allowing the lower edge upon completion of the expansion to move generally perpendicular to said side window, and wherein said body portion is constructed to have a smaller longitudinal length when it admits inflating gas than that of its extended but non-expanded state. - View Dependent Claims (7, 8, 9, 10, 11, 12, 14, 15, 16)

13. A head protecting airbag device comprising an airbag folded and housed above the upper edge of a window inside of a vehicle and expanded while being extended to cover the inner side of said window when it admits an inflating gas,
wherein said airbag includes: -
a body portion for covering the inner side of a side window positioned on the side face of the vehicle; and
a sheet-shaped flexible extension portion arranged on at least one longitudinal end side of said body portion, extending on the inner side generally perpendicular to said side window, and fixed at its leading end, removed from said body portion, on the vehicle body, and wherein said body portion is fixed at its upper edge upon completion of the expansion to the vehicle body while allowing the lower edge upon completion of the expansion to move generally perpendicular to said side window, wherein said body portion is housed, when said airbag is housed, so that it is covered with a roof head lining above the upper edge of said side window, and wherein said extension portion is housed, when said airbag is housed, so that it is covered with said roof head lining, can protrude downward, and is connected with said body portion above the upper edge of a window adjoining said side window.
