no. 1 example

[0059] The first embodiment of the present invention will be described below with reference to FIGS. 3 to 6 .

[0060] As shown in FIG. 3 , the lower surface of an airbag device 10 of the present invention is supported by a support frame 100 fixed on an inner panel 6 between a top panel (not shown) and a ceiling 4 .

[0061] Since the airbag device 10 is similar to the prior art, it will not be described in detail here, and a pair of support frames 100 that are not in the prior art will be described in detail below.

[0062] A pair of said support frames 100 are arranged on both sides of a center pillar 2 and fixed on an inner panel 6 between a top plate and a ceiling 4, and the length of the fixed support frames 100 corresponds to the inside of the car.

[0063] As shown in FIG. 4 , the support frame 100 is substantially in the shape of an "L" and includes a straight portion 110 and a lateral support portion 120 .

[0064] The straight portion 110 is connected to the inner p...

[0075] The second embodiment of the present invention will be described below with reference to FIGS. 7 to 10 .

[0076] An airbag device 10 has an airbag housing 12 provided with an airbag tube 16 . The airbag box 12 has a fastening portion 12a, which is fastened with bolts to a vehicle underframe, that is, an inner panel 6 between a top panel (not shown in the figure) and a roof 4.

[0077] The airbag case 12 bolted to the inner panel 6 is disposed on a boundary between a center pillar 2 and the roof 4 .

[0078] In addition, the airbag case 12 has a door 12b installed on a surface thereof facing the roof 4, and can be opened by the airbag tube 16 inflated.

[0079] Furthermore, the box door 12b is separated from the box body 12 at its lower end and opened when the airbag tube 16 is deployed. The box door 12b is provided with a break line 13a, which has a substantially "V"-shaped cutout, and is formed at the lower end and both ends to help the box door 12b to break away. ...

Abstract

A side air bag inflation structure for a vehicle is provided to protect passengers by quickly and stably inflating an air bag tube into a passenger compartment of a vehicle upon occurrence of vehicle crash. A support bracket(100) is fixed at an inner panel interposed between a roof panel and a head liner(4), and support an air bag module(10). The support bracket includes a vertical portion(110) fixed at the inner panel arranged between the roof panel and the head liner, and a hollow horizontal support portion(120) extended from the vertical portion so as to support the air bag module fixed at the inner panel. The horizontal support portion has a diameter gradually decreasing as it goes far from a center pillar trim(2). The support bracket is arranged at both sides from the center pillar trim.

Description

technical field [0001] The invention relates to a side safety airbag guide plate of an automobile, in particular to a side safety airbag guide plate of an automobile which can stably deploy a side airbag installed between a top plate and a ceiling when the automobile is hit . Background technique [0002] Car airbags, like seat belts, are a device used to protect drivers or passengers from injury when a car is hit. [0003] The airbag can be installed in the steering wheel in front of the driver's seat, in the glove box in front of the passenger seat, and on both sides of the car, that is, between the roof and the roof next to the door. Car airbags, like seat belts, operate using a crash detection sensor and an electronic control unit to protect occupants in the event of a car crash. [0004] When an impact occurs, the impact detection sensor sends a test transmission signal to the electronic control device, the electronic control device activates the safety airbag, and th...
