[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to an instrument panel disposed in a vehicle, and particularly to a technical field of a structure in which an opening for an airbag device formed in an instrument panel main body is closed by a separate panel member. .
[0002]
[Prior art]
Conventionally, an airbag device for protecting the occupant in the passenger seat from the impact at the time of a vehicle collision is provided on the back side of the instrument panel of the vehicle, and an opening is provided in a portion of the instrument panel body facing the airbag device. There is known an instrument panel formed so that a separate panel member is attached to the opening from the front side of the instrument panel body so as to close the opening (for example, see Patent Document 1).
[0003]
In the instrument panel of Patent Document 1, an opening is formed in a substantially horizontal upper wall of the instrument panel main body, and a rear edge of the upper wall extends obliquely forward and downward toward the back of the instrument panel. A vertical wall is formed, and a recess for storing articles is formed by the vertical wall and a lower wall connected to a lower end thereof so as to be recessed toward the back side of the instrument panel main body.
[0004]
However, the panel member is provided with a plate-shaped main body having a shape corresponding to the opening outer peripheral edge of the instrument panel main body upper wall, and a frame-shaped storage portion for storing the airbag device is provided on the back surface of the plate-shaped main body. It is protruding.

JP-A-10-59111 (page 3, FIG. 1 and FIG. 2)
[0006]
[Problems to be solved by the invention]
However, in the instrument panel of Patent Literature 1, the outer peripheral edge of the plate-shaped main body of the panel member is overlapped with the outer peripheral edge of the opening of the instrument panel main body from the front side. A step is generated between the upper surface of the instrument panel main body and the outer peripheral edge of the plate-shaped main body appears on the surface side, and the appearance of the instrument panel is poor.
[0007]
Therefore, a fitting wall is formed in the plate-shaped main body of the panel member, which is inclined in the same manner as the vertical wall constituting the article storage recess of the instrument panel main body, and the fitting wall is externally fitted to the vertical wall. It is conceivable to provide a sense of continuity between the member and the instrument panel main body to improve the appearance of the instrument panel.
[0008]
On the other hand, the storage wall of the panel member extends so as to guide the inflation of the airbag in an appropriate direction when the airbag device is activated, and the inclination angle of the storage wall and the inclination of the vertical wall of the instrument panel main body. The corners may be different from each other. In this case, when the fitting wall is formed on the panel member as described above, the inclination angles of the storage wall and the fitting wall are also different from each other, and as a result, an undercut portion is formed on one of the storage wall and the fitting wall. In order to remove the panel member from the mold during injection molding of the formed panel member, a new slide mold must be provided at a position corresponding to the undercut part of the mold, which increases the mold cost and costs Invite up. Further, it is conceivable to set the inclination angle of the vertical wall of the instrument panel main body so that an undercut portion is not formed between the storage wall and the fitting wall of the panel member. In this case, the shape of the vertical wall is considered. That is, the shape of the article storage recess cannot be freely set, and the degree of freedom in designing the instrument panel main body is reduced.
[0009]
The present invention has been made in view of such a point, and an object of the present invention is to externally fit the vertical wall (instrument-side fitting wall) of the instrument panel main body to improve the appearance of the instrument panel. When the panel-side fitting wall to be formed and the storage wall for guiding the inflation of the airbag when the airbag device is operated are integrally formed with the panel member, the slide die can be formed by devising the structure of the panel member. An object of the present invention is to reduce the cost by avoiding a new installation and to prevent the design flexibility of the instrument panel main body from being reduced.
[0010]
[Means for Solving the Problems]
In order to achieve the above object, according to the first aspect of the present invention, when the forming die for forming the panel member is moved in the drawing direction, the storage wall integrated with the panel member is bent.

As a result, the outer peripheral edge of the panel member is located in a portion that is recessed from the surface of the instrument panel main body, whereby the fitting portion between the instrument panel main body and the panel member has a step or panel member as in the related art. The outer peripheral edge of the instrument panel does not appear on the surface of the instrument panel, and a sense of continuity is obtained, and the appearance of the instrument panel is improved.
[0014]
Further, in the demolding step at the time of forming the panel member, first, the forming die for forming the inner surface of the storage portion is moved at a draft angle along the storage wall and separated from the storage wall, and thereafter, the molding for forming the panel side fitting wall is performed. The mold is moved at a draft angle along the panel side fitting wall. When moving the molding die of the panel-side fitting wall, the draft angle of the molding die is set differently from the draft angle of the molding die of the storage wall, and the molding die of the panel-side fitting wall defines the storage wall. Although it will be pressed, there is no molding die inside the storage part by the above process, and furthermore, since the storage side is formed so as to be bent and substantially comb-tooth separated from each other on the tip side, The storage wall pressed by the molding die of the panel-side fitting wall bends and deforms in the moving direction of the molding die, and the molding die of the panel-side fitting wall moves smoothly.
[0015]
As a result, the shape of the instrument panel-side fitting wall is freely set to prevent the design freedom of the instrument panel body from being reduced, and the panel-side fitting wall having the same inclination angle as the instrument panel-side fitting wall. And a storage wall extending so as to appropriately guide the airbag is integrally formed with the plate-shaped main body of the panel member, and a panel is provided without newly providing a slide mold between the storage wall and the panel-side fitting wall. The member can be removed from the mold, and the cost can be reduced.
[0016]
In the invention of claim 2, the thin hinge is interposed between the plate-shaped main body of the panel member and the panel-side fitting wall.
[0017]
Specifically, the present invention is directed to an instrument panel in which a panel member is attached to an opening of an instrument panel main body so as to close the opening.
[0018]
The instrument panel main body has an instrument panel-side fitting wall extending from the outer peripheral edge to the back side of the opening, and the panel member has a design surface and covers the opening of the instrument panel main body, A substantially rectangular frame-shaped storage portion projecting from the back surface of the plate-shaped main body and inserted into the opening to store the airbag device therein; and integrated with the plate-shaped main body so as to correspond to the storage portion. And a panel-side fitting wall formed integrally with the plate-shaped body via a thin hinge and fitted externally to the instrument-panel-side fitting wall. The portion has a storage wall facing the panel-side fitting wall, and the panel-side fitting wall is bent by the thin hinge and held in a form fitted to the instrument panel-side fitting wall, and is fitted in this form. Panel side mating wall at Inclination angle a configuration that is set different from each other and the mold venting angle of the housing wall.
[0019]
According to this configuration, since the panel-side fitting wall of the panel member is externally fitted to and held by the instrument panel-side fitting wall, the appearance of the instrument panel is improved as in the first aspect of the present invention.
[0020]
In addition, since the thin hinge is interposed between the plate-shaped main body of the panel member and the panel-side fitting wall, the inclination of the panel-side fitting wall and the storage wall in the form of being fitted to the instrument panel-side fitting wall outside. Even if the corners are different from each other, after the panel-side fitting wall is formed integrally with the plate-shaped main body in a shape extending in the same direction as the storage wall, the panel-side fitting wall is bent by a thin hinge to be exposed to the instrument panel-side fitting wall. It becomes possible to fit.
[0021]
Thereby, the shape of the instrument panel-side fitting wall is freely set to prevent the degree of freedom of design of the instrument panel main body from being reduced, and the panel-side fitting wall which is fitted to the instrument panel-side fitting wall, When the storage wall extending so as to appropriately guide the airbag is integrally formed with the plate-shaped main body of the panel member, the slide member is not newly provided between the storage wall and the panel-side fitting wall.

[0037]
Next, a molding die 71 for molding the panel member 41 having the above configuration will be described with reference to FIGS. 1, 5 and 6. The molding die 71 includes an upper die 73 for molding the front surface side of the panel member 41 and a lower die 75 for molding the back surface side. The upper die 73 is a fixed die, while the lower die 75 is It is configured so as to be able to approach and separate from it. The draft angle of the lower mold 75 is set to be equal to the inclination angle α ゜ of the panel-side fitting wall 47 with respect to the horizontal plane (shown only in FIG. 1).
[0038]
The lower die 75 is provided with a first slide die 77 corresponding to the inner surface of the storage part 53 of the panel member 41. The draft angle of the first slide die 77 is different from the draft angle α ゜ of the lower die 75, and is set to be equal to the projecting direction of the storage portion 53. The lower die 75 is provided with second slide dies 79, 79 (shown only in FIG. 5) for forming the front claw portion 51 and the rear claw portion 49. Reference numeral 79 moves horizontally and horizontally.
[0039]
When molding the panel member 41 using the molding die 71, first, as shown in FIG. 5, the upper die 73 and the lower die 75 are clamped, and a molten resin is injected into the cavity by a resin injection nozzle (not shown). Inject. In the subsequent demolding step, as shown in FIG. 6, the first slide die 77 is moved downward to position the upper end of the first slide die 77 below the lower end of the rear storage wall 55b.

[0042]
As described above, according to the instrument panel P according to the first embodiment, the front claw 51 and the rear claw 49 of the panel member 41 are connected to the peripheral edge of the hole 23 and the rear edge of the opening 11 of the instrument panel main body 1. When the panel member 41 is attached to the opening 11 by engaging with the panel panel 41, the panel-side fitting wall 47 formed integrally with the plate-shaped main body 43 is externally fitted to the instrument panel-side fitting wall 17a. The entire surface of the right side of the main body 1 is covered with the panel member 41. Thereby, a sense of continuity can be obtained from the step portion 27 on the front side of the instrument panel main body 1 to the concave portion 17, and the appearance of the instrument panel P can be improved.
[0043]
A plurality of slits 57, 57,... Are formed in the rear storage wall 55b of the storage portion 53 of the airbag device 7 protruding from the rear surface of the plate-shaped main body 43 of the panel member 41, and the rear storage wall 55b is bent. The lower mold 75 is moved along the draft angle after the first slide mold 77 is moved in the mold removing step at the time of molding, so that the rear storage wall 55b and the panel are formed. Even when the extending directions of the side fitting walls 47 are different from each other, the panel member 41 can be removed from the mold without newly providing a slide mold corresponding to the undercut portion formed therebetween.
[0044]
Thereby, the shape of the recess 17, that is, the shape of the instrument panel-side fitting wall 17 a is freely set, thereby preventing the design flexibility of the instrument panel main body 1 from being reduced. When the panel-side fitting wall 47 having the same inclination angle and the rear storage wall 55b for guiding the airbag are integrally formed with the plate-shaped main body 43 of the panel member 41, the cost can be reduced.
[0045]

The lower side of the fitting wall 47 swings back and forth with the thin hinge 83 as a fulcrum, as shown by an arrow A in FIG.
[0048]
A hole 85 is formed in the instrument panel-side fitting wall 17a of the instrument panel main body 1, while a hole 85 is inserted into the hole 85 on the back surface of the panel-side fitting wall 47 of the panel member 41. A claw portion 87 that engages with the 85 peripheral edge is formed integrally.
[0049]
When the panel member 41 having the above configuration is formed, as shown by a solid line in FIG. 8, the panel-side fitting wall 47 is formed in a developed shape so as to extend in the same direction as the storage wall 53. As a result, no undercut portion is formed between the rear storage wall 55b and the panel-side fitting wall 47. Therefore, the slit formed in the rear storage wall 55b in the first embodiment is omitted, and the panel member 41 is omitted. Can be removed.
[0050]
When attaching the panel member 41 formed as described above to the opening 11 of the instrument panel main body 1, the panel-side fitting wall 47 is bent by the thin hinge 83 as shown in FIG. Is engaged with the periphery of the hole 83. As a result, the panel-side fitting wall 47 is held in a form in which it is fitted to the instrument panel-side fitting wall 17a. When the panel-side fitting wall 47 is externally fitted, the storage wall 53 projects downward from the plate-shaped main body 43 so as to guide the expansion of the airbag in an appropriate direction as described above. The inclination angle of the fitting wall 47 is different from the draft angle of the mold of the storage wall 53.
[0051]
Therefore, in this embodiment, similarly to the first embodiment, the appearance of the instrument panel P can be improved. Further, since the thin hinge 83 is interposed between the plate-shaped main body 43 and the panel-side mating wall 47, the panel-side mating wall 47 is formed in the plate-shaped main body 43 in a shape extending in the same direction as the rear storage wall 55b. It can be molded integrally.
[0052]
As a result, the panel-side fitting wall 47 that fits over the instrument-panel-side fitting wall 17a and the rear-side storage wall 55b that guides the airbag are prevented while preventing the degree of design freedom of the instrument panel body 1 from being reduced. Is integrally formed with the plate-shaped main body 43 of the panel member 41, the panel member 41 can be removed from the rear storage wall 55b and the panel-side fitting wall 47 without newly providing a slide mold. Cost can be reduced.
[0053]
In the second embodiment, the panel-side fitting wall 47 is engaged with the periphery of the hole 85 of the instrument-panel-side fitting wall 17a by engaging the claw portion 87 of the panel-side fitting wall 47 with the instrument-panel-side fitting wall 17a. However, the present invention is not limited to this. For example, the two fitting walls 17a and 47 may be bonded by using an adhesive, or may be thermally welded. .
[0054]
Further, in the first and second embodiments, the door portion 63 is configured as a so-called double-door type including the front side portion 63a and the rear side portion 63b. However, the present invention is not limited to this. The door may be configured as a single hinge type with a thin hinge and a single door that opens on the rear side. Further, a reinforcing plate may be integrally provided on the back surface of the door portion 63. Further, the breakable portion 41a may be processed by a laser beam or the like after injection molding without being formed during the injection molding of the panel member 41 as in the first and second embodiments.
