Description

  The present invention relates to a cover device after the operation of an airbag device installed in an automobile.

There are known airbag devices for mitigating impacts on the human body during automobile collisions, and various proposals have been made. For example, in the apparatus of Document Nos. 1 and 2, an inflator that injects high-pressure gas into a recess formed in a decorative panel such as a dashboard in an automobile and a gas that is injected from the inflator at the time of a car collision are deployed in the vehicle interior. An outer bag with a lid (lid) so as to cover the opening of the recess and partition a part of the decorative panel, and so that there is no sense of incongruity with the decorative panel. And so on.
JP 2000-289554 A JP-A-6-72272

  In the airbag apparatus disclosed in Patent Documents 1 and 2, the inflator is activated via an acceleration sensor at the time of a collision of the automobile, and once the airbag is deployed, the inflator uses explosives, an igniter, sealed nitrogen gas, or the like. Therefore, normally, the airbag function cannot be restored unless the modularized airbag and inflator are completely replaced. This airbag device module requires some cost for replacement. In addition, it is normal for all airbags to be activated during a collision. Therefore, when the passenger seat, rear seat, etc. are combined, four modules are replaced, resulting in a high price. In addition, the insurance for the other vehicle is usually covered by insurance treatment, but there are many cases where insurance treatment for the car itself is not made, and the seat belt is irreversible in the event of an accident. Locks and all seats must be replaced. On the other hand, it is not always obliged to equip automobiles with airbag devices. Including compensation for hospitalization in the event of a collision, it will be a significant economic burden on the parties. In some cases, abandoned and unequipped. Further, when the collision vehicle is switched to use only on farm roads, forest roads, or on the premises of a business entity, there is a usage form in which an airbag equipment is not necessarily required in view of cost effectiveness. Thus, when using the automobile in a state where it does not function after the airbag device is activated, the lid portion divided by the H-shaped or I-shaped thin tear line portion that was torn when the airbag was inflated, There is no support at the torn part and it must be left in a state where it can move freely. It hindered driving.

  The present invention has been made in view of the above-described conventional problems, and one object of the present invention is to maintain a good design feeling of the decorative panel portion in the automobile when the airbag function is stopped at an extremely low cost. An object of the present invention is to provide a cover device for an actuated airbag capable of realizing comfortable driving and riding comfort. Another object of the present invention is to provide a cover device for an actuated airbag that can reduce a large economic burden at the time of a collision accident.

  In order to achieve the above object, the present invention is arranged in the interior of the vehicle interior filled with high-pressure gas by an inflator 26 that is disposed in the recess 20 provided from the decorative panel portions 14A and 14B and operates in the event of an automobile collision. For the lid 12 that covers the opening 201 of the recess 20 when the airbag 28 is folded in a non-actuated folded state, the outer edge 12a of the lid 12 after the airbag is actuated and only the outer edge is the original. The outer edge small lid portion 121 having an outer edge smaller than the outer edge of the outer shape of the outer edge of the outer edge small lid portion 121 is formed. And a cover device for an actuated airbag, characterized in that it has an external lid portion 30 having the same outer shape as that of the original lid portion. An air bag device is usually installed in a decorative panel such as a handle portion in front of the driver's seat or a dashboard portion in front of the passenger seat, but in any case, the activated air bag of the present invention is used. A bag cover device may be applied. The external lid part 30 is basically fitted from the surface with the original three-dimensional or planar outer shape of the lid part, but as long as the design feeling with the surrounding decorative panel part is not impaired. The color and pattern may be different from those of other decorative panel parts. Also, the three-dimensional outer shape may be variously changed. Normally, the airbag device is embedded in the interior of the decorative panel portion or in the recessed portion, and therefore it is necessary to remove it after operation and fit the external lid portion, so that the outer edge of the original lid portion. The part may have a shape along the adjacent dividing line.

  Moreover, the part (12a1) cut out from the external shape of the original cover part 12 is good in it being a part adjacent to the decorative panel main body (14A, 14B) part. When fitting the external cover part manufactured at low cost, it can be smoothly attached to the surface of the original cover part, and a good design feeling can be maintained. This makes it easier to employ a cover device that actually stops the airbag function when necessary.

  Further, the external cover 30 may be formed by integrally molding synthetic resin. Although it may be manufactured individually as a single item, costs can be reduced if mass production corresponding to demand is required.

  The actuated airbag cover device of the present invention is an airbag that is placed in a recess recessed from the decorative panel portion, is filled with high-pressure gas by an inflator that operates in the event of an automobile collision, etc., and is deployed in the vehicle interior. An outer edge small lid portion that covers the opening of the concave portion in a non-operating folded state of the airbag and cuts the outer edge of the lid portion after the airbag operation so that only the outer edge is smaller than the outer edge of the original outer shape. The externally mounted lid that is fitted to the surface of the small outer lid part and is substantially the same as the original outer shape of the lid in a state in which the airbag that has been deployed is returned and accommodated in the recess or is cut off in the middle of the airbag Because it has a structure with a part, the design of the decorative panel part in the car is maintained well at a very low cost, realizing a comfortable driving and riding comfort, The economic burden can be reduced. As a result, it is possible to enhance the repair of exterior panels, bumpers, mirrors, etc., which are more conspicuous in appearance, so that accident vehicles can be put into practical use early in daily business activities and daily use.

  Moreover, since the part cut out from the outer shape of the original lid part is a part adjacent to the decorative panel body part, only the outer edge part of the lid part before the collision is ground or polished, and the original lid part can be processed with less processing. The external cover portion having an external shape along the external shape of the external cover portion can be configured, and by manufacturing the external cover portion by molding, replacement and attachment can be easily performed at a low manufacturing cost.

  In addition, since the external lid is formed by integrally molding synthetic resin, for example, by molding in advance for each vehicle type or model, it can be manufactured at low cost and the economic burden on the accident party can be reduced. .

  The best mode for carrying out the present invention will be described below with reference to the accompanying drawings. FIG. 1 to FIG. 7 show a first embodiment of the present invention. In this embodiment, for example, a cover device for an actuated airbag applied to an airbag device for a driver's seat of a car is used. The form is shown. In FIG. 10, a handle 114 and an airbag device 116 </ b> A including an inflator and an airbag are installed in the center portion of the handle unit portion 112 in front of the driver seat 110, and the upper surface thereof is covered with the lid portion 12. Yes. The lid portion 12 is provided by being partitioned from the decorative panel portion 14A of the handle unit portion, and is integrally provided so as to form a part of the decorative panel portion 14A on the design.

In this embodiment, as shown in FIG. 8, the inflator 26 for gas injection and the high-pressure gas injected from the inflator are filled in the holding part 24 of the lid 12 and inflated at all times. An air bag 28 is disposed. Then, at the time of the collision of the automobile, when an acceleration sensor (not shown) detects the collision, the igniter is ignited to explode the explosive to generate gas, and as shown in FIG. This reduces the collision of the driver's upper body with the handle. The air bag shrinks and shrinks rapidly after inflation. In the figure, reference numeral 117 denotes a handle shaft fitting hole (not shown).

  In this embodiment, what is characteristic is that the outer edge 12a of the lid portion 12 after the operation of the airbag is cut out to form an outer edge small lid portion 121 in which only the outer edge is smaller than the outer edge of the original outer shape. This is because the external lid part 30 having substantially the same outer shape as that of the original lid part is fitted on the surface of the lid part 121. That is, after the operation of the airbag, the entire handle unit 112 is removed, and normally, the lid 12 that houses the inflator 26 and the airbag 28 is replaced here. In the present application, as shown in FIGS. As described above, the decorative panel main body portion, that is, in this embodiment, the portion 12a1 adjacent to the upper plate member of the connecting arm portion 16 is cut off along the cutting line t, and the outer edge small lid portion having an outer edge smaller than the outer edge of the original outer shape. 121 is formed. The excision of the outer edge portion of the original outer shape of the lid portion is determined according to the thickness of the external lid portion. For example, in the case of a thickness of about 1 mm to a few millimeters, the corresponding outer edge width is removed. It is done. Then, as shown in FIGS. 7A and 7B, the external cover 30 having the same outer shape as the original cover is fitted on the surface of the small outer cover 121 using the cut partial trace 12a2. To cover. The external lid 30 has a substantially hexagonal shape that is flat in a plan view similar to the original lid 12 or the small outer lid 121 except for the outer edge that is scraped as necessary. In this shape, an outer edge portion is formed so as to cover the shaved portion 121 from the outside. The external cover 30 is a cover body having a plate thickness of several millimeters that is formed in a half cracked hollow three-dimensional shape with the lower surface opened. A hook portion 31 that bends inward is formed on the outer edge of the external lid portion 30, and the hook portion 31 is attached to the shaved portion of the outer edge small lid portion 121 or other outer edge portion from the surface side. Are mated. Note that the hook portion 31 is not necessarily provided. In the figure, 32 is a through hole for the horn button. The decorative panel portion 14 is formed of, for example, reinforced plastic, and the external lid portion 30 is preferably made of the same material with the same texture and color sense, but is designed to be integrated with different materials. Or a colored cover may be used. Further, when the design atmosphere in the vehicle is brightened by using a unique coloring or pattern cover, it may be applied. When cutting out from the outer shape of the original lid portion 12, for example, the lid portion 12 may be removed and then ground by grinding or polishing, or laser, high-pressure water, thermal fusing, press cut, etc. Any ablation method may be used. When the external lid 30 is fitted to the outer surface of the small outer lid, the upper surface is lifted by the thickness of the external lid 30 from the state of FIGS. 3 and 4 as shown in FIG. However, on the design, there is almost no sense of incongruity with the surrounding decorative panel part, and it can be matched.

  The external lid 30 is preferably formed by integrally molding synthetic resin in advance corresponding to the vehicle type, model, etc., but is finished to a shape corresponding to the outer shape of the original lid by joining a plurality of divided materials. May be.

  When the external lid 30 is fitted from the surface of the small outer lid 121, the airbag that has already been deployed may be returned and accommodated in the recess 20 or may be cut off in the middle of the airbag and thereafter The external lid part 30 may be fitted to the outer side.
