Head protection airbag apparatus
First Claim
1. A head protection airbag apparatus comprising an airbag that is folded and received in an upper edge of a window on an inside of a vehicle, an upper edge of which is attached and fixed to a body of the vehicle, and inflated and protruding downward from a storage region by an inflation gas flowed from an inflator to cover the inside of the window,wherein the air bag includes:
- an inflation shielding section that is arranged to cover the inside of the window upon completion of inflation; and
an overlap inflation section that is communicated with the inflation shielding section and when the airbag is completely inflated, arranged on an inside or an outside of the vehicle of the inflation shielding section so that an inflation region of the overlap inflation section is overlapped with an inflation region of the inflation shielding section inflated by the inflation gas,wherein the overlap inflation section is configured to be completely inflated after the inflation shielding section is completely inflated,wherein the overlap inflation section has a generally rod-shaped exterior shape and is arranged to extend substantially along a front and rear direction on a substantially middle region of the inflation shielding section in an upward and downward direction,wherein the overlap inflation section is arranged to be overlapped with a pillar arranged adjacent to the window, as viewed from the inside of the vehicle, andwherein the overlap inflation section is arranged over the substantially entire region of the inflation shielding section in the front and rear direction of the vehicle.

Abstract
A head protection airbag apparatus includes an airbag that is folded and received in an upper edge of a window on an inside of a vehicle, an upper edge of which is attached and fixed to a body of the vehicle, and inflated and protruding downward from a storage region by an inflation gas flowed from an inflator to cover the inside of the window. The air bag includes an inflation shielding section that is arranged to cover the inside of the window upon completion of inflation and an overlap inflation section that is communicated with the inflation shielding section and arranged on an inside or an outside with respect to the vehicle of the inflation shielding section so that an inflation region of the overlap inflation section is overlapped with an inflation region of the inflation shielding section.

5. A head protection airbag apparatus comprising an airbag that is folded and received in an upper edge of a window on an inside of a vehicle, an upper edge of which is attached and fixed to a body of the vehicle, and inflated and protruding downward from a storage region by an inflation gas flowed from an inflator to cover the inside of the window,
wherein the air bag includes: -
an inflation shielding section that is arranged to cover the inside of the window upon completion of inflation; and an overlap inflation section that is communicated with the inflation shielding section and when the airbag is completely inflated, arranged on an inside or an outside of the vehicle of the inflation shielding section so that an inflation region of the overlap inflation section is overlapped with an inflation region of the inflation shielding section inflated by the inflation gas, wherein the overlap inflation section is configured to be completely inflated after the inflation shielding section is completely inflated, wherein the overlap inflation section has a generally rod-shaped exterior shape and is arranged to extend substantially along a front and rear direction on a substantially middle region of the inflation shielding section in an upward and downward direction, wherein the overlap inflation section is arranged to be overlapped with a pillar arranged adjacent to the window, as viewed from the inside of the vehicle, wherein an airbag constitution body constituting the airbag is configured so that, in a flatly deployed state of the airbag, the overlap inflation section is arranged adjacent to a lower side of the inflation shielding section to extend substantially along the front and rear direction, and wherein the overlap inflation section is communicated with the inflation shielding section through a communication part, and folded back at the communication part to be arranged on the inside or the outside of the vehicle of the inflation shielding section.

6. A head protection airbag apparatus comprising an airbag that is folded and received in an upper edge of a window on an inside of a vehicle, an upper edge of which is attached and fixed to a body of the vehicle, and inflated and protruding downward from a storage region by an inflation gas flowed from an inflator to cover the inside of the window,
wherein the air bag includes: -
an inflation shielding section that is arranged to cover the inside of the window upon completion of inflation; and an overlap inflation section that is communicated with the inflation shielding section and when the airbag is completely inflated, arranged on an inside or an outside of the vehicle of the inflation shielding section so that an inflation region of the overlap inflation section is overlapped with an inflation region of the inflation shielding section inflated by the inflation gas, wherein the overlap inflation section is configured to be completely inflated after the inflation shielding section is completely inflated, wherein the overlap inflation section has a generally rod-shaped exterior shape and is arranged to extend substantially along a front and rear direction on a substantially middle region of the inflation shielding section in an upward and downward direction, wherein the overlap inflation section is arranged to be overlapped with a pillar arranged adjacent to the window, as viewed from the inside of the vehicle, wherein the inflation shielding section includes a main inflation portion and a sub-inflation portion communicated with the main inflation portion to be completely inflated after the main inflation portion is completely inflated, wherein the overlap inflation section is communicated with the sub-inflation portion, and wherein a downstream-side communication part for communicating the overlap inflation section with the sub-inflation portion is set to have an opening area smaller than that of an upstream-side communication part for communicating the sub-inflation portion with the main inflation portion.
