Abstract

PURPOSE:To improve occupant constraining performance by fixing plural lateral rods into the supporting position of an air bag body in a storage container so as to support the air bag body by the lateral rods, and storing the air bag body in the folded state. CONSTITUTION:Plural lateral rods 23 are fixed to the supporting position of an air bag 18 in a storage container 13. That is, plural bolt holes are formed laterally at appropriate spaces below the fastening positions of the bolts 19 of the air bag body 18 in the storage container 13, and the bolt holes are respectively formed at the opposed side walls of the storage container 13. The lateral rods 23 formed of bolts, pins, or the like are respectively put in the mutually opposed bolt holes of the storage container 13 and fixed by nuts, spring nuts, or the like, and the lateral rods 23 are formed at the supporting part of the air bag body 18. Since the air bag body 18 is supported by the lateral rods 23, there is no fear of the air bag 18 falling below a gas generator, nor there is any fear of the folded storage state of the air bag 18 collapsing.

2. Description of the Related Art Conventionally, an airbag device has been known as a device for protecting an occupant such as a vehicle. This airbag device is disclosed in Japanese Utility Model Laid-Open Publication No. 2-38860,
No. 43890, and Japanese Utility Model Laid-Open No. 61-185642. Further, as an air bag cover for covering the air bag body of the air bag device in a folded and housed state, Japanese Utility Model Laid-Open No. 50-131742 and Japanese Patent Laid-Open No. Hei 4-1.
There are Japanese Patent Laid-Open No. 43142 and Japanese Patent Laid-Open No. 5-262195.

As shown in FIGS. 5 and 6, a conventional airbag apparatus 11 for side collision is provided on the side of a door 10 of a vehicle. In this airbag device 11, an inner panel of the door 10 is formed on a base plate 12, and a storage container 13 is fixed to the base plate 12 by bolts 14 and the like, and a gas generating member formed on one side of a lower portion of the storage container 13 is generated. The gas generator 15 is fixed to the storage container 13 in a state in which the gas ejection port 15a side of the gas generator 15 is inserted from the gas generator insertion opening 13a.

The container 13 is open at the top and has a gas ejection opening 13b into which the gas ejected when the gas generator 15 is operated is introduced. Storage container 13
The gas injection port 18a side of the airbag body 18 is fixed to the upper part of the with a bolt 19 or the like via a retainer.

The airbag main body 18 is folded and stored in the upper portion of the storage container 13, and an airbag cover 21 that covers the stored state is attached. Then, at the time of a side collision, the gas from the gas generator 15 is stored in the storage container 1
Air bag body 18 through the gas ejection opening 13b of No. 3
The airbag main body 18 is inflated, the airbag cover 21 is opened, and the airbag main body 18 is inflated to protect the occupant.

[0006]

In the conventional airbag device 11, since the storage container 13 is formed in a substantially quadrangular shape in cross section with the upper part open, as shown in FIG. Since the bag body 18 is folded and stored, it is pushed above the gas generator 15,
When the gas generator 15 is fixed, or after the airbag body 18 is stored, the folded and stored state of the airbag body 18 may be destroyed.

If the folded and stored state of the airbag body 18 is broken, there is a risk that the airbag body 18 cannot be inflated simply and quickly, and the folded state when assembled. The work must be carried out while holding it, and there is a risk that workability will deteriorate. Further, when the gas generator 15 is activated, a large pressure is applied to the storage container 13, which may deform the gas ejection opening 13b of the storage container 13.

The object of the present invention is to improve the strength of the storage container, to assemble the airbag body while keeping the folded and stored state of the airbag main body, and to assemble the gas generator. Work can be done easily and quickly, work efficiency can be improved, and the folded and stored state of the airbag body can be retained after assembly, and the occupant restraint performance by the airbag body can be improved. It is intended to provide a storage container for an airbag device, which is excellent in economic efficiency.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and a storage container for an airbag device according to claim 1 is a storage container having a gas ejection opening. A gas generator fixed to the storage container, and fixed to the upper part of the storage container so that gas ejected from the gas generator at the time of operation of the gas generator flows in through the gas ejection opening. In a storage container of an airbag device including an airbag main body, a plurality of horizontal rods are fixed to a supporting position of the airbag main body in the storage container, and the airbag main body is supported by the horizontal rod. To do.

[0010]

According to the storage container of the airbag device according to the first aspect of the present invention, a plurality of horizontal rods are fixed to the support position of the airbag main body in the storage container, and the airbag main body is fixed by the horizontal rod. Since it is supported, there is no risk of falling below the gas generator with the airbag body folded and stored.
There is no risk of collapse of the folded and stored state of the airbag body when storing the airbag body in the storage container, and the gas generator can be assembled easily and quickly, improving workability. Moreover, since a plurality of horizontal rods are fixed in the storage container, the horizontal rods function as a reinforcing rod, and it is possible to prevent the gas ejection opening of the storage container from being deformed when the gas generator is activated.
