Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an interior member structure mounted on an automobile or the like.

[0002]

2. Description of the Related Art As a technique of this kind, for example, as shown in FIG. 7, a door trim 1 as a "skin member" entirely covers a door inner panel 2 as a "structural member" and an armrest portion 3 is provided. As shown in FIG. 8, a synthetic resin material integrally formed, or the door trim 1 as a “skin member” completely covers the door inner panel 2 as a “structural member” as shown in FIG. Although it is the same, it is well known that the armrest portion 3a is formed as a separate body and fixed to the door inner panel 2 via the door trim 1 with the screw 4. Further, as shown in FIG. 9, the armrest portion 3b is formed with an opening 5 in the armrest portion 3b at a portion touched by an elbow of an occupant, whether the armrest portion 3b is integral with the door trim 1 or a separate body. It is also known that the cover 6 made of a material different from that of the portion 3b is locked by the clip 6a.

[0003]

However, in the case of the armrest portion 3 shown in FIG. 7, there is a risk that the armrest portion 3 itself will "flex" with respect to the load from above by the occupant's elbow, and a large amount of the armrest portion 3 from the back side. Since a strength member must be interposed, it causes a cost increase and weight increase. Also, FIG.
In the case of the armrest portion 3a shown in (4), the hole 4a of the screw 4 remains, and there is room for improvement in appearance even if a blind lid (not shown) is inserted. Further, in the case of the armrest portion 3b shown in FIG. 9, the cover 6 gives a different feeling from the armrest portion 3b,
There is room for improvement in appearance. Further, when the airbag device 7 as shown in FIG. 10 (see Japanese Utility Model Laid-Open No. 2-25345) is incorporated in the above-mentioned interior member structure, the opening 9 formed in the instrument panel 8 and the instrument. A predetermined distance is provided between the lid 11 supported by the panel 8 via the hinge 10 and opened by the expansion of the bag body (not shown) in the airbag device 7 when the lid 11 is opened. Since the gap 12 is required, the occupant feels a different feeling between the lid 11 and the instrument panel 8, and there is a problem that the appearance is not good.

That is, when the airbag apparatus is incorporated in the example of FIG. 9, the opening 5 formed on the upper surface of the door trim 1 or the armrest portion 3b as the "skin member" corresponding to the instrument panel 8 is installed in the instrument. A cover 6 corresponding to the opening 9 formed in the instrument panel 8 and covering the opening 5 is attached to the instrument panel 8 by the hinge 1.
Since it corresponds to the lid 11 supported via 0, a predetermined gap 12 required between the opening 9 and the lid 11 is
It is necessary even for the interior member structure, and there is room for improvement in appearance because of the required amount. Also, when the airbag device is incorporated into the example of FIGS. 7 and 8, the appearance is unsatisfactory because the predetermined gap 12 is required, and further, the door trim 1 or the armrest portions 3 and 3a as the skin member needs to be reinforced. Therefore, it will cause cost rise and weight increase.

Therefore, the present invention has been made in view of the above points, and an object of the present invention is to improve the strength and appearance of the interior member structure, reduce the cost and the weight, and An object of the present invention is to provide an interior member structure suitable for mounting an airbag device.

Covered by 38.

Reference numeral 48 is the armrest portion 20.
In the stay holding the lower core member 27, one end portion 48a is fixed to the nut 50 fixed to the door inner panel 2 by the bolt 49, and the other end portion 48b is fixed to the lower core member 27 of the armrest portion 20. Along the inside.

The door trim 23 has a core member 45 having the opening 21 as described above, a skin 46 made of vinyl leather covering the surface of the core member 45, and the core member 45.
The clip 47 is provided on the rear surface side of the above and is engaged with the recesses 39e and 39f on the opposite side where the projections 39c and 39d are formed.

The skin 46 is wound around and fixed to the edge of the opening 21, the upper end 46a is wound around the upper end 45a of the core 45, and the lower end 46b is wound around the core 45.
It is wound around and fixed to the lower end portion 45b of the. Reference numeral 51
Is a decorative member made of a cloth material, and is fixed so that the upper end portion 51 a is engaged in the recess 45 c of the core material 45 and the lower end portion 51 b covers the edge portion of the opening 21 of the core material 45.

FIG. 3 is a perspective view of the interior member structure A, and FIG. 5 is a perspective view of the armrest portion 20 and the door trim 23. To assemble the interior member structure A, first, the back plate member 26 and the lower core member 27 are fixed to the door inner panel 2 with the screws 25, and then the upper core member 28 is fixed to the back plate member 26 with the screws 25. The door trim 23 is attached to the back plate member 26 by the clips 47, 47.

As shown in FIG. 6, in the space 31 formed by the lower core member 27 and the upper core member 28, a nut 32 fixed to the door inner panel 2 is fixed by a bolt 33. In addition, an airbag device 34 that can generate a load that can be opened by disengaging the upper core member 28 from the lower core member 27 is mounted. The airbag device 34 is a sensor (not shown) fixed to the door inner panel 2 by a bolt 33 and detecting a sudden deceleration.
Of the inflator 35 capable of ejecting gas by means of the iron clip 30 which is arranged so as to surround a gas ejection port (not shown) of the inflator 35 and ejects the upper core material 28 with the lower core material 27 by the iron clip 30. A bag body 3 that can be inflated so as to generate a load that can be opened by opening
It consists of six.

As described above, according to the above-described embodiment, the armrest portion 20 has the support portion 22 and the door inner panel 2 is provided.
Since it is fixed on the door trim 23, it is not necessary to interpose a strength member in the door trim 23 itself, and the support portion 22 of the armrest portion 20 is not required.
The door inner panel 2 with the door trim 23
Can be covered, which improves the appearance.

Further, the armrest portion 20 is composed of the lower core material 2
The upper core member 28 and the upper core member 28 are formed in a shell shape, and do not give a different feeling to the occupant. Therefore, the strength is improved and the appearance is not impaired, and the airbag device is suitable for mounting. Further, since the airbag device is fixedly mounted on the back plate member 26, it is not necessary to specially reinforce the armrest portion 20, and it is possible to achieve weight reduction and cost reduction. Then, at the time of a side collision (side impact), the inflator 35 of the airbag device 34 ejects gas to expand the bag body 36, so that the impact value of the occupant can be alleviated.
