Description: BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to an airbag for a head protection airbag device, and more particularly, to an upper edge side of a window between pillars in a vehicle interior. The present invention relates to an airbag that is folded and stored and that is deployed and inflated so as to cover the interior of the pillar portion and the window when the inflation gas flows. 2. Description of the Related Art Conventionally, an airbag of a head protection airbag device can be deployed and inflated so as to cover the inside of a window formed in a door or the like when an inflation gas flows therein. It was configured to be folded and housed on the upper edge side of the window inside the vehicle (see Japanese Patent Application Laid-Open No. 11-321532). [0003] This airbag has a gas inflow portion which allows inflation gas to flow to separate an inner side wall portion and an outer side wall portion from each other, and a non-inflow portion which does not allow inflation gas to flow in. In addition, the gas inflow portion is configured to include, on the upper edge side, a gas supply path portion disposed along the front-rear direction of the vehicle, and an expansion shielding portion disposed below the gas supply path portion. The expansion shielding portion covers the inside of the window formed in the door or the like and the inside of the center pillar portion, and is arranged in plural in the longitudinal direction of the vehicle so as to be divided into a non-inflow portion. This is a configuration provided with an inflatable portion. [0004] Usually, a seat is arranged inside the vehicle in the center pillar portion, and near the center pillar portion, the airbag is deployed and inflated between the center pillar portion and a headrest in the seat. In consideration of interference between the center pillar portion and the occupant, it is preferable that the inflatable portion is disposed on the vehicle interior side of the center pillar portion to cover the inside of the vehicle with a good cushioning property. However, in the case of a vehicle in which the gap between the center pillar portion and the headrest is set to be small, there is a possibility that the headrest may interfere when the inflatable portion is deployed and inflated. An object of the present invention is to solve the above-mentioned problems, and to provide an airbag for a head protection airbag device capable of reducing interference with a headrest as much as possible even when a gap between a pillar portion and a seat is narrow. The purpose is to provide. An airbag of a head protection airbag device according to the present invention is folded and housed on the upper edge side of a window between pillars inside a vehicle,
When the inflation gas flows in, it is configured to expand and inflate so as to cover the inside of the vehicle between the pillar portion and the window, so that the inflation gas can flow in and expand so as to separate the inner side wall portion and the outer side wall portion. A gas inflow portion, and a non-inflow portion that does not allow inflation gas to flow in. The gas inflow portion is provided on the upper edge side with a gas supply passage portion disposed along the front-rear direction of the vehicle, and a gas supply passage portion. An inflatable shielding portion that is disposed below and covers the inside of the vehicle with the pillar portion and the window at the time of deployment and inflation, the inflatable shielding portion is partitioned into a non-inflow portion, and extends along the longitudinal direction of the vehicle. A plurality of inflatable portions are provided, the inflatable portion being arranged so as to cover the vehicle interior of the pillar portion, and the window-side inflatable disposed to cover the interior of the window. The airbag of the head protection airbag device, comprising: The front adjacent portion and the rear adjacent portion adjacent to each other before and after the pillar portion-side inflating portion are configured such that an inflow portion through which an inflation gas flows is opened on the gas supply path portion side, and the pillar portion-side inflating portion is formed. However, it is characterized in that the gas supply path portion side is substantially closed by a non-inflow portion, and an inflow portion communicating with the front adjacent portion and the rear adjacent portion is opened at the lower end side. And [0007] In the airbag of the head protection airbag device according to the present invention, when the inflation gas is discharged from the inflator, the gas supply path portion is inflated by flowing the inflation gas, and is inflated. The inflation portion expands and inflates the inflation gas by flowing the inflation gas from an inflow portion opened on the gas supply path portion side. At this time, since the pillar portion-side inflatable portion is substantially closed on the gas supply path portion side by the non-inflow portion, the front adjacent portion and the rear adjacent portion are expanded and inflated with the front adjacent portion and the rear adjacent portion. It is pulled by the adjacent portion and expands downward without inflow of the inflation gas. Then, after deployment, the pillar-portion-side inflatable portion is inflated by flowing inflation gas from the front adjacent portion and the rear adjacent portion, which have substantially completed inflation, through the inlet port opened to the lower end side. . That is, in the initial stage of deployment and inflation of the airbag, the pillar portion-side inflatable portion is deployed downward so as to eliminate folding in a thin plate-like state in which the inflation gas does not flow, and then formed on the lower end side. The inflation gas flows from the inflow port to be inflated and expands so as to increase the thickness. Therefore, even when the gap between the pillar portion and the headrest of the seat is narrow, the pillar portion-side inflatable portion is deployed in a thin plate-like state at the initial stage of the deployment and inflation of the airbag. It can be deployed so as to cover the inside of the pillar portion of the vehicle.
Then, since the inflation gas flows from the front and rear adjacent portions after the deployment, the pillar portion-side inflatable portion can be inflated thickly so as to improve the cushioning property. Therefore, in the airbag of the head protection airbag device according to the present invention, interference with the headrest can be reduced as much as possible even if the gap between the pillar portion and the seat is narrow.
