Embodiment Construction

[0038] Hereinafter, an airbag device according to an embodiment will be described. figure 1 and figure 2 It is an exploded perspective view showing the steering wheel 10 and the airbag device 30 .

[0039]

[0040] The airbag device 30 is configured to be attachable to the steering wheel 10 of the vehicle. Hereinafter, the overall configuration of the steering wheel 10 and the airbag device 30 will be schematically described.

[0041]

[0042] The steering wheel 10 is used to steer the vehicle, and includes a wheel body 12 , spokes 14 , and a center member 16 . The disk main body 12 is formed in an annular shape, and is a portion that receives a steering force from a person. The central member 16 can be connected to the front end portion of the steering shaft extending away from the driver. The spokes 14 extend from the inner peripheral portion of the disc main body 12 toward the center thereof, where they are joined to the central member 16 . Here, three spokes 14 a...

Abstract

Provided is an airbag device capable of suppressing direct contact between a corner of a folded part of a cover formed during unfolding of an airbag and the airbag. The cover is provided with: a tearing line (842); a cover unfolding part which is divided by the tearing line (842) and is unfolded during expansion of the airbag; and folding parts (882, 884) which are formed by at least part of the tearing line and are adjacent to the cover unfolding part. The corner is formed on the folding parts (882, 884). On a packaging material (35), a predetermined broken line (352) which is broken during the expansion of the airbag (32) is formed, and the packaging material (35) consists of at least one opening sheet (359) formed by the predetermined broken line (352). At least part of the opening sheet (359) is clamped between the airbag (32) and the corner during expansion of the airbag (32).

Description

technical field [0001] The present invention relates to an airbag device. Background technique [0002] Patent Document 1 describes an airbag device mounted on a steering wheel of a vehicle. The airbag device has an airbag and an airbag cover for storing the airbag. A tear line is formed on the airbag cover, and the airbag cover is broken at the tear line when the airbag is inflated and deployed. Through this breakage, a plurality of deployment portions are formed on the airbag cover. In Patent Document 1, among the plurality of deployment parts, the upper deployment part is opened upward, and the two lower deployment parts are respectively opened to the left and right. Thus, an opening is formed in the airbag cover. The airbag projects toward the driver through the opening. [0003] Patent Document 2 describes an airbag device mounted on a steering wheel of a vehicle. This airbag device has an airbag, a packaging sheet that covers the airbag, and a cover that houses t...
