Description

  The present invention relates to an instrument panel structure that can effectively use a space in an instrument panel of an automobile.

FIG. 10 is a side sectional view of the instrument panel 51 (hereinafter referred to as instrument panel) cut along the front-rear direction of the vehicle. The instrument panel main body 52 of the instrument panel 51 is provided with an assistant tray 55 (storage section) that can store tissue paper and the like, and is configured to improve the usability of the passengers.
The assistant tray 55 is provided between an air bag grid 53 provided so as to cover an opening of an air bag (not shown) and a glove box 54 with a manual opening / closing lid used as a container. .

As a conventional technique related to such a tray, for example, as in Patent Document 1, in the case where the airbag main body storage opening is not equipped with an airbag, it is used as a container case and the rigidity of the instrument panel main body is improved. A possible technique is disclosed.
JP-A-10-109570

  By the way, as shown in FIG. 10, the size of the storage portion of the assistant tray 55 in the height direction is preferably large enough to store small items. However, the size of the storage portion is regulated by the shape and size of the airbag grid 53 and the glove box 54. The necessary size of the airbag grid 53 is determined by the size of the airbag, and the glove box 54 needs to be provided with a certain size so as to accommodate the vehicle verification and the like. Therefore, the space between the air bag grid 53 and the glove box 54 becomes relatively narrow, and the height at which the assistant tray 55 is formed cannot be secured sufficiently.

  Further, the instrument panel body 52 is molded using a molding die, and a punching die used at the time of molding is only a slope angle α on the vehicle upper rear side with respect to the horizontal plane 57 in order to reduce the number of the molding dies. It is designed so that it can be pulled out in an inclined direction. Therefore, the shape of the assistant tray 55 integrally formed with the instrument panel main body 52 in the vehicle front-rear direction needs to be formed with the gradient angle α of the punching die, and the upper surface portion 56 of the assistant tray 55 is also formed with the gradient angle α. ing.

In the above configuration, for example, when the upper surface portion 56 is moved upward by the height h1 in order to widen the interior of the assistant tray 55 (see reference numeral 56a), the gradient angle α is kept constant. In the state, the airbag grid 53 becomes small. Further, when the size of the air grid 53 is kept constant, the upper surface of the instrument panel main body 52 must be moved upward by the height h2 (see reference numeral 52a). When the instrument panel body 52 is moved upward, the design of the instrument panel 51 is changed, the shape of the instrument panel body 52 is increased, and the mold cost of the instrument panel body 52 is increased.
Therefore, even if there is a sufficient space that can be used inside the instrument panel 51, the area and the storage volume of the bottom surface of the assistant tray 55 cannot be increased without moving the instrument panel body 52 upward.

  The present invention has been made in view of such circumstances, and its purpose is to secure the draft angle of the mold and keep the top surface of the instrument panel body at a constant height in the assistant tray. Is to provide an instrument panel structure that can be widely formed.

  The present invention includes an air bag grid attached to an instrument panel main body, and a storage portion provided below the air bag grid, wherein the storage portion is provided with an upper surface portion extending in the vehicle front side direction. In the instrument panel structure, the upper surface portion of the storage portion includes a first upper surface portion in which a storage opening side surface in the vehicle front-rear direction is formed by an assistant cover separate from the instrument panel main body, and a vehicle in the vehicle front-rear direction. A front surface is formed with a second upper surface portion formed integrally with the instrument panel main body, and an attachment portion for the airbag grid is provided on the assistant cover.

Further, the surface of the second upper surface portion is provided to be inclined at a first angle on the vehicle upper side rear with respect to the horizontal plane, and the surface of the first upper surface portion is on the vehicle upper rear side with respect to the horizontal surface at the first angle. Inclined at a smaller second angle.
The steering support member positioned in the vicinity of the second upper surface portion may be assembled with an attachment portion that is integrally formed from the second upper surface portion.
Further, air-conditioning bezels are integrally provided on both the left and right sides of the airbag storage portion of the airbag grid.

Since the assistant cover is used as the attachment portion of the airbag grid and the upper surface portion of the storage portion, the number of parts can be reduced.
In addition, despite having the original draft of the instrument panel body, the assistant cover slope is set to be smaller than the draft, so without increasing the height position of the upper surface of the instrument panel, The storage volume of the storage part of the assistant tray can be increased.

By fixing the instrument panel main body to the steering support member near the attachment portion of the assistant cover and the attachment portion of the airbag lid, the attachment portion of the assistant cover and the attachment portion of the airbag grid can be strengthened.
Furthermore, the strength of the airbag grid itself can be increased by disposing bezels on both sides of the airbag. Thereby, even if the air bag grid is formed to be long in the width direction, the material can be made thin and the rigidity can be increased.
In addition, since the bezel mounting portion is integrally formed with the air bag grid, it is possible to eliminate the gap between the boundary portions and improve the design.

The tightening operation of the screw 40 has a structure in which the storage opening 6 of the airbag can be used as a work hole.

  The ratio of the lengths of the upper surface portions 19a and 19b in the longitudinal direction of the vehicle is determined by the position at which the mounting portion 39 is mounted on the steering support member 26, as shown in FIG. In order to further increase the size of the storage portion 24, the ratio of the length of the upper surface portion 19b may be increased. However, the position of the steering support member 26 is determined in relation to the components incorporated in the instrument panel 1. Since the steering support member 26 is disposed at the same height as the assistant cover 12, the upper surface portion 19b cannot be made larger.

In the instrument panel structure according to the best mode for carrying out the present invention, the assistant cover 12 is used as the attachment portion of the airbag grid 3 and the first upper surface portion 19b of the storage portion 24, so that the number of parts can be reduced. Can be achieved.
Moreover, although the instrument panel body 2 has the original draft angle α, the assistant cover 12 is provided so that the slope β is smaller than the draft angle α. The storage capacity of the storage portion 24 of the assistant tray 12 can be increased without increasing the height.

By fixing the instrument panel body 2 to the steering support member 26 in the vicinity of the assistant cover mounting portion and the airbag lid mounting portion, the mounting portion of the assistant cover 12 and the mounting portion of the airbag grid 3 can be strengthened.
Furthermore, the strength of the airbag grid 3 itself can be increased by providing the bezels 7 and 8 on both sides of the airbag. Thereby, even if it forms so that the air grid 3 may become long in the width direction, while being able to make the material thin, rigidity can be enlarged.
Moreover, since the bezel attachment part (attachment opening 9b, 10b) was integrally formed with the air bag grid 3, the clearance gap between those boundary parts can be eliminated, and the designability can be improved.

Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and various modifications and changes can be made based on the technical idea of the present invention.
For example, in the above-described embodiment, an accessory case in which the storage portion 24 of the assistant tray 4 is not provided with a cover has been described as an example. However, if the storage portion has a fixed bag-like cross section (the assistant tray 4 of this embodiment) It is also possible to apply to the housing part of the second glove box.

Further, although the assistant cover 12 is disposed on the upper surface portion 19 of the assistant tray 4, the assistant cover 12 may be disposed on the lower surface portion 15 and the left and right side surface portions 16 and 17 of the assistant tray 4.
Furthermore, the assistant tray 4 can be provided in the same structure with two assistant trays 4 in the storage portion 24, that is, both the upper and lower surface portions 19 and 15 of the storage portion 24, or both the left and right side portions 16 and 17. For example, an assistant tray having a larger storage capacity can be formed.
