Description

[Detailed description of the device]

[0001]

[Industrial applications]

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

[0002]

[Prior art]

 As a conventional instrument panel structure of this type, there is a structure as shown in FIGS. 1 to 3. That is, 1 is an instrument panel installed in the passenger compartment of the passenger car 2, and an airbag unit 4 is arranged on the back side of the instrument panel 1 near the passenger seat 3.

The airbag unit 4 is fixed via a bracket 6 to a steering member 5 provided on the back side of the instrument panel 1. Further, the airbag unit 4 includes a support arm 9 for supporting a deployment door 8 that closes an airbag inflation opening 7 formed on the instrument panel 1, and a closed state of the deployment door 8. A locking member 10 for holding the vehicle is provided. For example, when an abnormal impact force is generated due to a collision of the vehicle body or the like, the detonator in the airbag unit 4 explodes and the inside of the airbag unit 4 is exploded. The airbag 13 inflates, and the inflated airbag pushes the deployment door 8 up to the position indicated by the chain line with the hinge portion 11 as a boundary, and the inflated airbag is inflated from the opening 7 to the upper part of the instrument panel. This is for the safety of the passenger 12.

Further, in the conventional example shown in FIG. 4, the deployment door 8 and the outside of the airbag unit 4 are connected by a connecting member 15 having a thin fragile portion 14, and the closed state of the deployment door is always maintained. When the airbag 13 is inflated by the detonation of the detonator caused by the generation of the abnormal impact force, the fragile portion 14 of the connecting member 15 is broken by the bulging force, and the deployment door 8 is opened as the fulcrum 16. It is like this.

[0005]

[Problems to be solved by the device]

 However, in the instrument panel having such a structure, the deployment door 8 for closing the opening 7 for inflating the airbag is provided, but the deployment door 8 is always provided. Has a locking member 10 or a connecting member 15 for closing and holding the opening 7 by the deployment door 8. The dimensional accuracy of the locking member 10 or the connecting member 15 or the assembling accuracy. It is difficult to accurately attach and maintain the deployment door 8 to the opening 7 provided in the instrument panel due to the accumulation error of the instrument panel, and the quality of the instrument panel having the deployment door is poor. There was a defect.

[0006]

[Means for Solving the Problems]

 The present invention has been made in view of such a conventional problem, and a ridge or a groove is formed on an edge of an opening provided in an instrument panel, and a deployment door of a deployment door attached to the opening is further formed. Closure of the deployment door is formed by forming a concave groove or a convex line which engages with the convex line or the concave groove on a side facing the opening side line, and engaging means of the convex line and the concave line. Provided is an instrument panel for an automobile, which can maintain the state and can improve the closing position accuracy of the deployment door with respect to the opening.

[0007]

【Example】

 Hereinafter, the present invention will be described in detail with reference to the embodiments shown in the drawings.

In FIGS. 5 and 6, reference numeral 21 denotes an instrument panel having an airbag unit 20 provided on the back side thereof, and the instrument panel 21 has an airbag accommodated in an airbag unit 22. An opening 24 is formed to allow the bulge of 23.

The opening 24 is covered with a deployment door 25 for always closing the opening. The deployment door 25 has a flexible plate-like structure. The core material 26, a foam layer 27 layered on the core material 26, and an outer skin 28 attached to the surface of the foam layer 27, and the deployment door 25 is flexible. I have.

Further, a concave groove 29 is formed on the rising edge of the opening 24, and the rising edge of the deployment door 25 is fitted into the concave groove 29 corresponding to the concave groove 29. The ridges 30 to be formed are formed. Since the groove 29 and the ridge 30 are formed by molding at the time of molding the instrument panel 21 and the deployment door 25, it is necessary to enhance the precision of engagement between the groove 29 and the ridge 30. it can. A part 26 'of the core member 26 of the deployment door 25 is provided on the back side of the core member 26 so as to be fixedly supported by the instrument panel core member 21'.

As described above, in the present embodiment, the attachment holding of the deployment door 25 attached to the opening portion 24 provided in the instrument panel is provided at the rising edge of the opening portion. Since the concave groove 29 and the projection 30 provided on the rising edge of the deployment door 25 are engaged (engaged) with each other, the accuracy of attachment of the instrument panel to the deployment door is improved. It is possible to provide an instrument panel with excellent quality.

Further, when the airbag is inflated, the deployment door bends due to the inflation force of the airbag, so that the engaging force between the projection and the groove is surely released, and the inflation operation of the airbag is surely performed. Therefore, the operational reliability of the airbag device is enhanced.

In the above embodiment, the concave groove 29 is formed on the rising edge of the opening and the convex line 30 is formed on the rising edge of the deployment door 25. However, as shown in FIG. 7, the convex line 30 is formed on the opening. Alternatively, the groove 29 may be provided in the deployment door.

[0014]

[Effect of device]

 As described above, the present invention provides an instrument panel 21 having an opening 24 for inflating an airbag and an instrument panel 21 having a deployment door 25 attached to the opening 24. According to this, the instrument panel is provided with the recessed groove 29 and the ridge 30 that mesh with each other on both the rising edge of and the rising edge of the deployment door 25 facing the rising edge. The attachment and holding of the deployment door 25, which is attached to the opening 24 provided in the instrument panel, is provided in the concave groove 29 provided in the rising edge of the opening and the rising edge of the deployment door 25. Since the structure is such that it is engaged (engaged) with the convex ridges 30, the accuracy of attachment with the deployment door to the instrument panel is high. Rukoto can, instrument panel with excellent quality wear at the offer.

Further, when the airbag is inflated, the deployment door is bent by the inflation force of the airbag, so that the engaging force between the projection and the groove is surely released, and the inflation operation of the airbag is surely performed. Therefore, the effect that the operation reliability of the airbag device is enhanced can be obtained.
