Problems solved by technology

[0005] However, the airbag shell of the described structure is very heavy, which goes against the trend of lightweighting in recent years.
In addition, this structure also needs to consume a lot of necessary resources, which also goes against the trend of energy saving
Also, as the weight of the airbag case increases, the mounting portion of the airbag device requires greater strength.

Embodiment

[0032] Below, just for implementing the embodiment of the present invention, by Figure 1~4 to explain.

[0033] Figure 1~4 It is a figure explaining the airbag device of this invention with which a passenger's seat is equipped.

[0034] 11 is a casing for maintaining the airbag 1 when it is housed in the airbag case 12 . The housing 11 is made of the same woven fabric as the airbag 1 in order to accommodate the airbag 1 in a folded state, and then it is sewn on a bottomed box having the same shape as the airbag 1 and having an opening at the top.

[0035] The casing 11 made of woven cloth is provided with a connection hole 11a and an installation hole 11b for connecting the gas generator 5 at the bottom of the casing. in addition figure 2 In the example shown above, at one end of the opening, there are notches 11c designed to engage with hooks 12ab of the airbag housing 12 described below on both sides.

[0036] In the case of an airbag device including such a woven fa...

Abstract

Disclosed is an air bag device wherein fastening sections between an engagement member and a lower surface member are prevented from being disconnected during deployment of an air bag. Said air bag device is provided with an air bag case (12) wherein is installed an inflator (5) that supplies gas to the air bag (1) housed in the air bag case (12); and an article, such as a fabric housing (11), which holds the air bag (1) when the same is housed in the air bag case (12). The fabric housing (11) is formed into a bottomed box the ceiling of which is open. The air bag case (12) is provided with an opening (12aa) for inserting the fabric housing (11). In this opening (12aa), the air bag case (12) comprises the engagement member (12a) provided with hooks (12ab) for engagement with an instrument panel; and the lower surface member (12b) which is fastened to this engagement member (12a). The engagement member (12a) and the lower surface member (12b) are disposed in an overlapping manner in such a way that the engagement member (12a) is positioned inside the lower surface member (12b) at the locations of the fastening sections (12c) for fastening the two members (12a, 12b). Due to the above, the fastening sections are not susceptible to disconnection during deployment of the air bag.

Description

technical field [0001] The present invention relates to an airbag device installed in, for example, an automobile. Background technique [0002] In order to ensure the safety of drivers and passengers, several safety devices are installed on the car. An airbag device that deploys the airbag with the gas generated by the gas generator in the event of an emergency such as a collision is also one of the safety devices. [0003] Wherein, as Patent Document 1, the airbag device on the passenger seat is as Figure 7 As shown, the hook portion 2b provided near the opening of one side wall 2a of the airbag housing 2 is hung on the engaging hole 4aa of the vertical wall 4a provided on the inner side of the instrument panel 4 . and, Figure 7 1 in the figure is an airbag, 3 is a strip cover covering the airbag 1, and 5 is a gas generator. [0004] However, since the airbag device is mounted on a vehicle in a fixed folded shape, and the direction in which the airbag is extended when ...
