Problems solved by technology

Therefore, it is impossible to precisely control the discharge timing, discharge speed, and discharge amount of the gas discharged from the opened vent hole to the outside in accordance with the form of collision with the occupant of the deployed airbag.
Furthermore, in the airbag known from Patent Document 1, since the vent hole cover for closing the vent hole is sewn, the timing of gas discharge is controlled in accordance with the form of collision with the occupant of the airbag. , discharge speed and discharge volume, it has to be designed into a complex structure, which becomes the main cause of cost increase

Embodiment 1

[0033] like figure 1 As shown, the vehicle 10 is equipped with an airbag device 20 . This airbag device 20 is when the collision energy acts on the vehicle 10, by the inflator 21 (refer to image 3 , Figure 4 ) to deploy the airbag 30 in the vehicle interior 11 by the high-pressure gas generated. The airbag 30 is deployed on the front side of the occupant Mn seated on various seats such as the driver's seat 12 , the passenger's seat 13 , and a rear seat not shown to restrain the occupant Mn for protection. In this embodiment, a device for protecting an occupant Mn (driver Mn) seated on the driver's seat 12 will be described as an example of the airbag device 20 .

[0034] Hereinafter, the airbag device 20 will be described in detail. figure 2 The airbag 30 seen from the front side of the vehicle 10 is shown. like image 3 , Figure 4 As shown, the airbag device 20 is composed of an inflator 21 , a retainer 22 , a fixing ring 23 , and an airbag 30 indicated by dotted l...

Embodiment 2

[0081] The airbag of Example 2 will be described. Figure 8 means from vehicle 10( figure 1 The structure of the airbag 30A of Example 2 seen from the front side of ).

[0082] In the airbag 30A of the second embodiment, the front side panel 41A is constituted by two base fabrics 51A and 52A. The first base fabric 51A and the second base fabric 52A are set to have substantially the same size. The base fabrics 51A and 52A have substantially the same structure as the base fabrics 51 and 52 of the first embodiment.

[0083] The first and second overlapping portions 61A and 62A have the same configuration as the first and second overlapping portions 61 and 62 of the first embodiment. However, the overlapping amount Wr of the overlapping portions 61A and 62A has a constant width. The first and second non-joint portions 61aA, 62aA have the same structure as the first and second non-joint portions 61a, 62a of the first embodiment.

[0084] The first overlapping portion 61A and t...

Abstract

The present invention discloses an airbag (30) having first and second panels (31, 41) joined along a peripheral portion (31a, 41a). The second sheet (41) is composed of a plurality of base fabrics (51-53). The plurality of base fabrics are arranged along the circumferential direction, and have overlapping portions (61-63) in which mutually adjacent end portions (51a, 52a, 53a) overlap each other. At least a part of each of the overlapping portions has non-joint portions (61a to 63a) that are not joined to each other, and gas in the airbag can be discharged through the non-joint portions.

Description

technical field [0001] The present invention relates to an airbag deployed based on gas generated by an inflator, and more particularly to a vehicle airbag. Background technique [0002] For example, when collision energy acts on the vehicle, the vehicle airbag is deployed in front of the occupants seated on the driver's seat and the passenger's seat to protect the occupants. [0003] Such airbags have vent holes. The vent hole is a hole for venting a part of gas to the outside in order to restrict an excessive rise in internal pressure when the airbag is deployed. The size of the vent hole remains at the preset state without changing. Therefore, it is impossible to precisely control the discharge speed and discharge amount of the gas discharged from the vent hole to the outside in accordance with the collision state of the occupant of the deployed airbag. [0004] And, from the initial stage when the airbag starts to deploy in front of the occupant, the gas in the airbag...
