Problems solved by technology

[0007] However, in the structure of the above-mentioned conventional airbag door portion, only a weak portion is provided at the junction between the airbag door and the instrument panel made of different materials. Partial breakage of the vulnerable part may cause debris to fly toward the interior of the vehicle compartment

Embodiment Construction

[0036] Hereinafter, the present invention will be described in detail based on embodiments of the drawings.

[0037] Figure 1 to Figure 7 It is a figure which shows the structure of the airbag door part concerning embodiment of this invention.

[0038] Such as figure 1 and figure 2 As shown, the airbag door 1 with the structure of the present embodiment is disposed in the interior R of the vehicle compartment on the upper surface portion 2a of the instrument panel 2, which is a large resin component. The airbag of the airbag device 3 on the rear surface 2 b side of the instrument panel 2 is configured to be inflatable and deployable toward the interior R side of the vehicle compartment. Therefore, the airbag device 3 is composed of: an airbag box 31, which is box-shaped, and is attached to the rear surface 2b side of the upper surface portion 2a of the instrument panel 2 corresponding to the position of the airbag door portion 1; The bottom of the airbag box 31, the upper...

Abstract

PROBLEM TO BE SOLVED: To secure a stable deployment behavior of an airbag by receiving a load applied to an airbag door part by a high-rigidity part at the expansion and deployment of the airbag firstly, by absorbing the load of an amount which flows up to a low-rigidity part by the elongation of the low-rigidity part to a deployment direction of an airbag door, and by suppressing the generation of fracture at a member change region, and to suppress the deterioration of external appearance by absorbing thermal deformation caused by an in-cabin environment by the low-rigidity part.SOLUTION: In a structure of an airbag door part 1 which is arranged in a cabin R, and different from an instrument panel 2 in a peripheral region in material quality, a high-rigidity part reinforcing wall 14 and a low-rigidity part notch 15 are formed between an airbag opening fracture part 12 formed at the airbag door 11 and a member change region 13 located at a periphery of the airbag operation fracture part 12, the reinforcing wall 14 is formed at the airbag opening fracture part 12 side, and the notch 15 is formed at the member change region 13 side.

Description

technical field [0001] The present invention relates to a structure of an airbag door provided on an instrument panel of an automobile or the like. Background technique [0002] Conventionally, an airbag device including an airbag folded and housed in a predetermined position inside the instrument panel is provided on the rear side of the upper surface of the instrument panel in front of the passenger seat side of an automobile or the like. In order to protect the occupant of the passenger seat sitting inside the vehicle compartment from impact load, the stored airbag inflates and deploys toward the occupant side when gas is supplied. Therefore, an airbag door is provided on the upper surface of the instrument panel so that the airbag can be inflated and deployed into the vehicle compartment. [0003] Such as Figure 9 As shown, such an airbag door portion 50 constitutes a part of an instrument panel 51, and includes an airbag door 53 having an airbag split portion 52 forme...
