2. Description of the Related Art In recent years, most passenger vehicles are equipped with a driver airbag device and a passenger airbag device as standard equipment in order to protect an occupant from an impact such as a collision accident. The driver-seat airbag device is generally mounted on a horn pad portion of a steering wheel, and the passenger-seat airbag device is an instrument panel 10 that is a vehicle interior member assembled in front of a passenger compartment as shown in FIG. It is stored inside the front of the passenger seat. Therefore, when the instrument panel 10 receives a pressing force of the airbag 22 that has started to inflate when the airbag device 20 is actuated, a portion corresponding to the airbag device 20 for the passenger seat receives the pressure on the passenger compartment side. An airbag door 15 that opens to is provided.

The instrument panel 10 is mainly composed of a synthetic resin panel base material 11 injection-molded into a required shape. The instrument panel 10 is of a type composed only of the panel base material 11 and has a skin on the outer surface of the panel base material 11. It is roughly classified into a type in which the material 12 is adhered (corresponding to this in FIG. 7), a type in which a skin material and a cushion material are adhered to the outer surface of the panel substrate 11, and the like. Here, the panel base material 11 is formed of a relatively hard synthetic resin material such as PP (polypropylene) or ASG on the premise of the intended use of the instrument panel 10 in which various in-vehicle devices are mounted. Therefore, in the case of the air bag door 15 which is integrally formed on the panel base material 11 and always constitutes a part of the base material 11, a strong pressing force of the air bag 22 is generated especially at a low temperature. There is a risk of damage to the product when it is applied, which may cause problems in strength and safety. Therefore, an insert member 25 for connecting and supporting the panel base material 11 and the airbag device 20.
Is attached to the back surface of the airbag door 15 to prevent damage and scattering of the airbag door 15 and its peripheral parts.

The conventional insert member 25 is a metal molding member made of a metal such as steel,
In the type corresponding to the double door type airbag door 15 including the two door panels 15a and 15b, as shown in FIG. 8, the door panels 15a and 1 formed on the panel base material 11 are formed.
Fixed bracket 2 in the shape of a rectangular frame, which is fixed so as to surround the planned cleavage line 16 formed along the outer edge line of 5b.
6 and movable brackets 27, 27 mounted inside the opening of the fixed bracket 26 so as to face each other. The fixing bracket 26 includes a tubular body portion 28 that is locked to the airbag device 20, and the tubular body portion 28.
A fastening plate portion 2 integrally formed with the panel base material 11 and caulked around the airbag door 15 on the back side of the panel base material 11.
9, an airbag device 20 and a panel substrate 1
1 is connected and supported. In addition, each movable bracket 2
Reference numerals 7 and 27 denote a support panel 30 welded or screwed to the tubular portion 28 of the fixed bracket 26, and a corresponding door panel 15a, 1 hinged to the support panel 30.
It is composed of a movable panel 31 which is caulked and bonded to the back surface of 5b. In the panel base material 11 on which such a metallic insert member 25 is mounted, the airbag door 1
5, the respective door panels 15a and 15b and the peripheral portion of the back surface of the airbag door 15 are reinforced, and the strength sufficient to withstand the pressing force of the expanding airbag 22 is imparted.

[0005]

In the insert member 25, the support panel 30 of the movable bracket 27 is firmly fixed to the tubular portion 28 of the fixed bracket 26, and is shown in FIG. 9 (a). As described above, the support panel 30 and the movable panel 31 are formed so as to be simply bendable at the bending fulcrum (hinge portion) 32, and when the airbag 22 presses the movable panel 31 from the inside, Movable panel 3
No. 1 was designed to open outward with the bending fulcrum 32 as the center. However, in the airbag door 15 having such a configuration, as shown in FIG. 9B, the outer edge line side end 15c of the door panel 15a (15b) to which the movable panel 31 is crimped interferes with the panel base material 11. As a result, the openable angle of each door panel 15a (15b) becomes small, which may impede the smooth inflation and deployment of the airbag 22. Moreover, when the inflating and deploying airbag 22 forcibly presses the movable panel 31 in the open regulation state, the door panel 15a (15b) is changed to the door panel 15a (15b) due to the interference between the end portion 15c and the panel substrate 11. There is a risk that the rib 33, which is pushed in the direction of arrow A in FIG. 2 and is used for crimping the door panel 15a (15b) and the movable panel 31, is damaged and the door panel 15a (15b) is separated and scattered from the movable panel 31. Be done.

The insert member 25 has a fixed bracket 26 and a movable bracket 27 as described above.
Instrument panel 1 since all are made of metal
In addition to causing a weight increase of 0, the movable panel 31
Since the opening inertial force of the door increases, the above-mentioned door panel 15a
It is also pointed out that there is an inconvenience that promotes separation and scattering of (15b).
Further, since the mounting of the insert member 25 to the panel base material 11 has to adopt a caulking method that requires a large number of man-hours, there is a problem that the cost increases, and the panel base material 11 made of the synthetic resin and the metal insert. Since the member 25 is made of a different material, it is pointed out that there are drawbacks such as poor recyclability.

[0017]

Next, the operation of the airbag door 15 having the insert member 35 of the present embodiment constructed as described above mounted on its back surface will be described.

As described above, in the insert member 35 of the embodiment, the fixed bracket 36 and the movable bracket 37 are individually injection molded, and then the both brackets 3 are formed.
6 and 37 are attached to the back surface of the panel base material 11 and the back surface of the airbag door 15 by welding and bonding at the same time based on the vibration welding method. Thereby, in the fixed bracket 36, the joining plate portion 39 is joined to the peripheral portion of the back surface of the airbag door 15, and in the movable bracket 37, each movable panel 4 is joined.
2, 42 are joined to the back surfaces of the corresponding door panels 15a, 15b. Thus, in the insert member 35 of the embodiment,
Since both the fixed bracket 36 and the movable bracket 37 are formed of an olefinic thermoplastic elastomer, vibration welding can be performed on the panel base material 11 and the airbag door 15 under the same conditions, and at the same time, they are welded and joined together. It can be installed.

When the instrument panel 10 in which the insert member 35 is mounted on the back surface of the panel base material 11 is installed in front of the passenger compartment of the vehicle, the air bag device fixed in advance to the vehicle body constituent member 13. The inflator 21 of 20 is aligned with the tubular body portion 38 of the fixed bracket 36 and the support panel 41 of the movable bracket 37, and is provided on both brackets 36, 37 and is aligned with the first locking hole 40 and the first locking hole 40. The hook-shaped locking pieces 23 provided on the inflator 21 are correspondingly inserted into the two locking holes 45 (FIG. 1). At this time, each hook-shaped locking piece 23 of the airbag device 20 is inserted into the first locking hole 40 of the fixed bracket 36 with almost no play, and the second locking of the movable bracket 37. It is inserted into the hole 45 in a desired loose fitting state (since the second locking hole 45 is formed in a vertically long shape). Therefore, in the movable bracket 37, before the operation of the airbag device 20, the joining plate portion 39 of the fixed bracket 36 and the movable panels 42, 42 are aligned with each other so that the support panel 41 is not locked to the airbag device 20. Is held in the first position.

When the air bag device 20 is operated under the condition that the insert member 35 is attached, the pressing force of the air bag 22 which has started to inflate is the movable bracket 3.
The movable panels 42, 42 in FIG. 7 are applied to each of the movable panels 42, 42, whereby the pressing force of the airbag 22 is applied to the respective door panels 15a, 15b of the airbag door 15.

Here, when the pressing force of the air bag 22 is applied to the movable bracket 37, the conditions (1) and (2) will be described later. That is, the fixed bracket 36 is locked to the airbag device 20, and the movable bracket 37 is not locked to the airbag device 20 yet.
Breakage has not yet started at the planned cleavage portion 43 of the movable bracket 37, and the movable panels 42, 42 are integrally joined into one plate. Therefore, when the above conditions and are combined, the stress due to the pressing of the airbag 22 concentrates on the planned outer edge cleavage line 16a rather than the central planned cleavage line 16a.
A fracture will occur at. Then, when the breakage at the planned outer edge tear line 16b progresses and is completed, the airbag door 15 is separated from the panel base material 11 to be in a free state, and the movable bracket 37 is not locked to the airbag device 20 either. The airbag door 15 and the movable bracket 37 are integrally moved upward to a second position where the support panels 41, 41 of the bracket 37 are locked to the airbag device 20 (FIGS. 3 and 6 (b)). ). At the time when the movable bracket 37 is locked by the airbag device 20 and stopped, the breakage at the central tear line 16a has not started yet.

The rupture at the planned outer edge cleavage line 16b is completed,
When the movable bracket 37 moves upward and is locked by the airbag device 20 and stopped at the second position, the airbag 2
The pressing of 2 causes breakage at the planned cleavage line 16a. Here, since the airbag 22 is inflated in a state in which the center of the upper surface is projected, at the planned tearing portion 43 of the movable bracket 37 and the planned tearing line 16a of the airbag door 15, first, a partial breakage occurs at each intermediate portion. Is induced (Fig. 6 (c)). Then, when partial rupture starts in the intermediate portion in each of the planned cleavage portion 43 and the central rupture line 16a, the entire rupture proceeds at a stretch as the pressing force due to the inflation of the airbag 22 increases. .

In this way, the rupture of the planned cleavage line 16 at the outer peripheral cleavage line 16b is completed, and the panel substrate 1
After the airbag door 15 separated from No. 1 is moved upward together with the panel base material 11, when the breakage at the planned tearing portion 43 and the central tearing line 16a is completed, the airbag door 15
Door panels 15a, 15b and movable panels 42, 4 of
An open displacement of 2 is allowed. As a result, the movable panels 42, 42 rotate about the hinge portion 44 while being pressed by the inflating airbag 22, and are opened to the passenger compartment side together with the corresponding door panels 15a, 15b (FIG. 4 and FIG. 6 (d)).

At this time, since the movable panels 42, 42 are opened in a state where the door panels 15a, 15b of the airbag door 15 are floated from the panel base material 11, the movable panels 42, 42 are integrated with the movable panels 42, 42. The ends 15c of the door panels 15a, 15b that are open to the front are preferably prevented from interfering with the panel substrate 11, and both door panels 15a, 1
5b is opened smoothly (FIGS. 5 and 6 (e)).

As described above, the insert member 35 of this embodiment is used.
Then, each door panel 15a, 15 of the airbag door 15
When the movable bracket 37 joined to b is moved upward and protruded by a required amount, the movable panels 42 and 42 are integrally opened with the door panels 15a and 15b, so that both door panels 15a and 15b and the panel base material are opened. 11, interference with the door panels 15a and 15b is prevented, opening of the door panels 15a and 15b is not restricted, and the door panels 15a and 15b are not restricted.
It is possible to preferably avoid the occurrence of inconveniences, such as being separated from the movable panels 42, 42 and scattered. Also, each door panel 15
Since a and 15b are opened to an appropriate opening angle, the inflation and deployment of the airbag 22 is not hindered.

Further, in the insert member 35 of this embodiment, since the fixed bracket 36 and the movable bracket 37 constituting the member 35 are both made of the same kind of synthetic resin, the rear surface of the panel base material 11 and the airbag. The back surface of the door 15 can be joined and fixed at the same time based on a vibration welding method or the like, and the mounting work can be facilitated and the number of steps can be reduced to reduce the cost.

Further, since the insert member 35 of the embodiment is made of synthetic resin as described above, the insert member 35 is made lighter in weight than the conventional metal insert member 25 shown in FIG. Instrument panel 10
It can contribute to weight reduction. Furthermore, since it is formed of the same type of synthetic resin as the panel base material 11, when the vehicle in which the instrument panel 10 is installed is scrapped, the panel base material 11 can be disposed of with the insert member 35 being disposed of. Therefore, it can contribute to the improvement of recyclability.

In the above embodiment, the fixed bracket 36
The case where the movable bracket 37 is configured as a completely separate member has been illustrated, but when the pressing force of the airbag 22 is applied, the movable bracket 37 is easily separated from each other, which hinders the opening of the door panels 15a and 15b of the airbag door 15. If not required, they may be formed as a single member that is appropriately connected.

In the embodiment, two door panels 15 are provided.
Although the insert member 35 corresponding to the double-opening type airbag door 15 composed of a and 15b has been exemplified, the insert member targeted by the present application is a single-opening type airbag door consisting of one door panel, four door panels. It is also applicable to those that correspond to a four-way opening type airbag door.

Further, in the above-mentioned embodiment, the two-layer type instrument panel 10 has been exemplified, but the insert member 35 in this embodiment is provided in the single-layer type instrument panel constituted only by the panel base material 11. It can also be applied to airbag doors.

Further, the airbag door to which the insert member 35 of the present application can be applied is the instrument panel 1 described above.
In addition to those provided at 0, those provided at door panels, pillar garnishes, etc. are also included.
