Airbag, airbag device and airbag exhausting method
First Claim
1. An airbag configured to be inflated and deployed by being supplied with gas into an interior thereof comprising:
- an inner surface forming the interior of the airbag;
an outer surface on an opposite side of the inner surface, the outer surface facing an exterior of the airbag;
a vent hole formed on the airbag; and
a strap connected at one end to the airbag and at the other end to a component of the airbag or a mounting component of the airbag,wherein the vent hole is arranged in an area where one portion of the outer surface and its corresponding inner surface portion overlap with another portion of the outer surface such that the vent hole is covered by one of the overlapping one and another portions of the outer surfaces when the airbag is pulled by the strap, andwherein the one and another portions of the outer surface remain outside of the interior of the airbag when the one and another portions of the outer surface overlap when the airbag is pulled by the strap.

Abstract
[Object] To provide an airbag, an airbag apparatus, and an air-discharging method of the airbag which are able to reduce the pressure loss during inflation and deployment of the airbag, or is able to demonstrate the impact absorbing capability of the airbag apparatus efficiently depending on the physical structure of an occupant.
[Solving Means] The airbag apparatus of the present invention includes a gas generator 1 configured to generate gas under predetermined conditions, an airbag 2 connected to the gas generator 1 and configured to be inflated and deployed, and a retainer 3 configured to store the airbag 2, and the airbag 2 includes a protrusion 4 which forms a portion protruding outward partly on the airbag 2, a vent hole 5 formed on the protrusion 4, a strap 6 connected at one end to the protrusion 4 and at the other end to the interior of the airbag 2, and an insertion hole 7 configured to guide the other end of the strap 6 into the interior of the airbag 2, and the vent hole 5 is arranged in an area where the protrusion 4 and the airbag 2 are overlapped with each other when the protrusion 4 is pulled by the strap 6.

24. An air-discharging method of an airbag configured to be supplied with gas in an interior thereof and inflated and deployed comprising:
-
forming a vent hole on the airbag; closing the vent hole on an outer surface of the airbag by deforming the airbag such that one portion of the outer surface and its corresponding inner surface portion are folded onto another portion of the outer surface so as to form overlapping outer surface portions that remain outside of the interior of the airbag, wherein the vent hole is covered by one of the overlapping outer surface portions; and discharging the gas in the airbag by opening the vent hole by deforming the airbag such that the one and another portions of the outer surface are not overlapping.

-
25. An air-discharging method of an airbag configured to be supplied with gas in an interior thereof and inflated and deployed comprising:
-
forming a protrusion protruding outward from an outer surface area of the airbag, wherein a connection of the outer surface area to the protrusion circumscribes around a base of the protrusion; forming a vent hole on the protrusion or the outer surface area of the airbag; closing the vent hole by pressing an outer surface of the protrusion against the outer surface area of the airbag; opening the vent hole by filling the protrusion up with gas so as to stand upright from the outer surface area of the airbag such that the connection of the outer surface area to the protrusion remains around the base of the protrusion; and discharging the gas in the airbag.
