Embodiment 1

[0053] The following combination figure 2 and image 3 A first embodiment of the present invention is described.

[0054] Such as figure 2 and image 3 As shown, a driver's airbag device A of the present invention includes: a gas generator 4 that ignites the primer to generate gas; an airbag 5 that is caused by the gas generated by the gas generator 4 to expand and expand to the driver; Covering the cover body 3 of the gas generator 4; a fastening piece 6, which accommodates the gas generator 4, the safety airbag 5 and the cover body 3, and is fixed on a cover part 2 of a handle; A horn piece 7 mounted on the fastening piece 6 and matched with a steering wheel 100 .

[0055] The horn piece 7 and the fastening piece 6 are separated and fixed together by a fastening bolt 72 , and a horn spring 76 is inserted on the outer surface of the fastening bolt 72 to elastically support the horn piece 7 .

[0056] In addition, the outer surface of the fastening sheet 6 has more than...

Embodiment 2 7

[0072] The following combination Figure 4 The second to seventh embodiments of the present invention are described through Fig. 11 .

[0073] Such as Figure 4 As shown in FIG. 11, the second to seventh embodiments A1 to A6 of a driver's airbag device A of the present invention include: a gas generator 4 that ignites the primary detonator to generate gas; The airbag 5 caused by the gas to expand and deploy to the driver; a cover body 3 covering the gas generator 4; a fastening piece 6, which accommodates the gas generator 4, the airbag 5 and the cover body 3, and fixed on the cover 2 of a handle; a horn piece 7 installed on the fastening piece 6 and matched with the steering wheel 100.

[0074] In addition, the horn piece 7 and the fastening piece 6 are separated and fixed together by a fastening bolt 72, and a horn spring 76 is inserted on the outer surface of the fastening bolt 72 to elastically support the horn piece 7 and the fastening piece 6. The fastening piece 6. ...

Embodiment 2

[0078] Figure 4 to Figure 6 In the shown second embodiment A1 of the invention, the same parts as those of the first embodiment are not repeated here. Each paired hole 22 of a cover 2 is "T" shaped, including a transverse hole 222 and a straight hole 221; a bend 225 extends inward from an upper surface of the transverse hole 222, making the transverse The width of the middle portion of the hole 222 is smaller and the width of both ends is larger. The end holes 223 extend downward from both ends of the transverse hole 222 to form an elastic member 224 connected to an upper portion of the straight hole 221 .

[0079] That is, the matching holes 22 include a horizontal hole 222 of a predetermined length that is arranged on one side surface of the cover 2 , and a straight hole 221 of a predetermined length that extends downward from the middle position of the horizontal hole 222 . , to form a roughly "T" shape.

[0080] In addition, the end holes 223 extend downward from both ...

Abstract

A driver's airbag module assembly structure including: an inflator for generating gas by igniting an exploder; an airbag inflated toward a driver by the gas generated by the inflator; and a cage covering the inflator. A mounting plate is provided for accommodating the inflator, the airbag, and the cage in a cover member. A horn plate is installed between the mounting plate and a steering wheel. The mounting plate has a plurality of fixing clips formed at its outer surface. The cover member has a plurality of coupling holes coupled with the fixing clips and the horn plate is provided with a bracket having an angled tip and a fastening hole. The steering wheel is provided with a groove having an angled step corresponding to the bracket of the horn plate. Hooks of a mounting plate push flexible pieces formed at coupling holes of a cover to allow the mounting plate and the cover to be easily coupled with each other. In addition, since the hooks are closely inserted into lower horizontal holes, movement of the hooks can be reduced. Further, the hooks do not separate from the coupling holes when the airbag is deployed.

Description

[0001] This application is a divisional application of the original application (application date: October 20, 2006; application number: 200610140224.8; invention name: driver's airbag device structure). technical field [0002] The invention relates to a driver's safety airbag device structure, in particular to a driver's safety airbag device structure that can be installed on the steering wheel and easily combined. Background technique [0003] In general, an airbag structure for automobiles is a safety device used to reduce injuries caused by impacts, and after being impacted, it is placed on a steering wheel, or a groove between the driver and the steering wheel, or The air bag between a passenger and the groove is then inflated. The airbag configuration operates independently of the seat belt. [0004] The airbag for the driver and passenger is configured with a gas generator that ignites the primer to generate gas. The inflation of the gas generated by the gas genera...
