Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a structure of an instrument panel in which an airbag device is installed in an instrument panel of a vehicle, particularly in an instrument panel on a passenger side of a passenger car.

[0002]

[Prior Art]

 As a conventional instrument panel structure of this type, there is a structure as shown in FIG. That is, reference numeral 1 denotes an instrument panel, which is formed on a core material 2, a foam cushion layer 3 formed on the front side of the core material 2, and a surface of the foam cushion layer 3. It is made up of the outer skin 4 which is formed. A window 5 for inflating an airbag is formed in the instrument panel 1, and an air bag grid 6 that constantly closes the window 5 is provided in the window 5. The structure of the air bag grid 6 includes a core material 7 having a hinge portion 10, a foam cushion layer 8 layered on the front side of the core material 7, and a skin 9 applied to the surface of the foam cushion layer 8. The core material 2 of the instrument panel and the core material 7 of the air bag grid 6 are integrally connected by a mounting screw 11.

Reference numeral 12 denotes a steering member arranged on the back side of the instrument panel 1. A metal frame 13 is fixed to the steering member 12 by screwing, and further, to the metal frame 13, An airbag unit 14 located on the back side of the window 5 is fixed and held.

If an abnormal impact force acts on the airbag unit 14 due to a vehicle collision or the like, the airbag unit 14 is detonated, and as a result, the airbag is inflated, the airbag lid 6 is pushed open, and the airbag 5 is opened through the window 5. The bag bulges out to ensure passenger safety.

[0005]

[Problems to be solved by the device]

 However, in such a conventional instrument panel structure, since the core material 2 of the instrument panel 1 and the metal frame 13 that holds the airbag unit 14 are separate members, the number of constituent parts increases. However, there is a problem that assembly workability and economy are poor, and since the work of attaching the metal frame 13 to the steering member 12 and the work of attaching the instrument panel 1 to the vehicle body are performed in separate steps, the metal frame 13 The positional relationship between the mounting position and orientation of 13 and the window 5 of the instrument panel 1 tends to be unstable, and the positional accuracy of the airbag unit 14 with respect to the window 5 decreases, which causes the window of the airbag to fall. It was considered that the bulging accuracy from No. 5 was poor.

[0006]

[Means for Solving the Problems]

 The present invention has been made in view of such a conventional problem, and an air bag case for accommodating and holding an air bag unit is integrally formed in a part of a core material forming an instrument panel to form an air bag unit. The instrument panel that incorporates the instrument panel improves the workability and economy of the assembly, and in addition, in the event of a car collision, an airbag that accurately expands the airbag contributes to the safety of passengers. To provide.

【Example】

 The present invention will be described in detail below based on the embodiment shown in FIG.

Reference numeral 21 denotes an instrument panel according to the present embodiment. The instrument panel 21 includes a core member 23 integrally forming a storage recess 22 for storing an airbag unit, and the core member 23 having the above-mentioned structure. A foam cushion layer 24 is formed on the surface of the storage recess 22 excluding the opening, and a skin 25 attached to the surface of the foam cushion layer 24.

An air bag grid 27 is attached to the opening 26 of the storage recess 22 by a mounting screw 28. The air bag grid 27 includes a core member 30 having a hinge portion 29 and a core member 30. The foam cushion layer 31 is formed on the surface of the material 30, and the skin 32 is attached to the surface of the foam cushion layer 31.

An air bag unit, that is, an inflator 33 and an air bag 34 are fixedly held inside the storage recess 22. The storage recess 22 is supported by the steering member 36 via the bracket 35.

The above is the structure of the present embodiment, and according to this instrument panel structure, the storage recess 22 for assembling the airbag unit is formed in a part of the core member 23 that constitutes the instrument panel. Since the core member 23 is integrally molded at the time of molding, the positional accuracy between the airbag unit installation position and the air bag grid setting position is improved, and stable operation of the airbag can be expected. Further, since the storage recess 22 for storing and holding the airbag unit and the core material 23 of the instrument panel are integrally configured, the metal frame shown in the conventional example can be omitted to reduce the number of parts. As a result, assembly workability and economic efficiency are greatly improved.

[0012]

[Effect of the device]

 As described above, according to the present invention, the housing recess 22 for housing and fixing the airbag unit is integrally formed on a part of the core member 23 forming the instrument panel, and the air bag grid is formed at the opening of the housing recess 22. Since this is an instrument panel to which 29 is attached, the positional accuracy between the position where the airbag unit is installed and the position where the airbag bag is set is improved, and stable operation of the airbag can be expected. Further, since the storage recess 22 for storing and holding the airbag unit and the core material 23 of the instrument panel are integrally formed, the metal frame shown in the conventional example can be omitted and the number of parts can be reduced. As a result, the workability of assembling and economic efficiency can be greatly improved.
