エアバッグ展開時に破断する自動車用エアバッグ装置に
関するものである。DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to an automobile airbag device, in particular, to an automobile airbag device in which a locking portion that locks an airbag cover to an instrument panel is
This invention relates to an automobile airbag device that ruptures when the airbag is deployed.
従来、第１２図乃至第１５図に示されるようなエアバッ
グ装置が実開昭５８−９７０６８号で提案されている。Conventionally, an airbag device as shown in FIGS. 12 to 15 has been proposed in Japanese Utility Model Application No. 58-97068.
この技術は助手席乗員用に装備されるエアバッグ装置を
助手席前方でインストルメントパネル８の裏側に格納す

設定された係止部材４でインストルメントパネル８に固
定した技術である。This technology stores the airbag device installed for the front passenger seat behind the instrument panel 8 in front of the passenger seat, and also stores the airbag device installed on the instrument panel 8 in front of the passenger seat when the airbag 5 (see Figure 13) is deployed. A deployable airbag cover 1 is attached. As shown in FIG. 13, the detailed structure is such that the upper end of the airbag cover 1 is fixed to the instrument panel 8 via the hinge part 7. Further, this is a technique in which the lower end is fixed to the instrument panel 8 with a locking member 4 that is set to break when a load of a predetermined amount or more is applied.
このエアバッグ装置は、車両衝突時９図示しない車両の
衝突を検知する検知手段からの信号によりインフレータ
６からガスが発生し、エアバッグ５が展開しはじめる。In this airbag device, when a vehicle collides, gas is generated from the inflator 6 in response to a signal from a detection means (not shown) for detecting a vehicle collision, and the airbag 5 begins to deploy.
このエアバッグ５の展開によりエアバッグカバ−１の裏
側からエアバッグカバー１を押圧する荷重が作用する。Due to this deployment of the airbag 5, a load that presses the airbag cover 1 is applied from the back side of the airbag cover 1.
従って、エアバッグカバー１の下端をインストルメント
パネル８に固定している係止部材４が第１４図に示され
るように破断するとともに、上端を固定しているヒンジ
部７が塑性変形し、このヒンジ部７を軸としてエアバッ
グガバー１が展開する。これにより。Therefore, the locking member 4 that fixes the lower end of the airbag cover 1 to the instrument panel 8 is broken as shown in FIG. 14, and the hinge portion 7 that fixes the upper end is plastically deformed. The airbag cover 1 expands around the hinge portion 7. Due to this.
エアバッグ５はエアバングカバーに阻止されることなく
、助手席乗員を拘束するように展開する。The airbag 5 deploys so as to restrain the front passenger seat occupant without being blocked by the airbag cover.
しかしながら、このようなエアバッグ装置においては、
エアバッグ５が展開する際に、エアバッグカバー１を押

荷重が伝達されにくくなり、係止部材４の破断が遅延し
、エアバッグカバ−１の展開が遅れてしまう恐れがある
。However, in such an airbag device,
When the airbag 5 deploys, the load that presses the airbag cover 1 is used to break the locking member 4 that fixes the lower end of the airbag cover 1. While it is located at the bottom end of cover 1,
The load generated by the deployment of the airbag 5 is concentrated near the center of the airbag, as shown in FIG. 15. As a result, much of the load is used to deform the airbag cover 1. Therefore, it becomes difficult for the load to be transmitted to the locking member 4, and there is a possibility that the breakage of the locking member 4 is delayed and the deployment of the airbag cover 1 is delayed.
本発明は上記問題に鑑み、エアバッグカバーの中央部近

せることを目的とする。In view of the above problems, the present invention effectively transmits the load generated when the airbag deploys to the locking portion of the airbag cover by preventing a large load from acting near the center of the airbag cover. The purpose is to break the locking part of the airbag nogkahar almost simultaneously with the start of the airbag deployment, and to deploy the airbag cover without delaying the deployment of the airbag.

エアバッグ装置。In order to achieve the above object, two airbag devices according to the present invention include an airbag that is inflated by gas supplied from an inflator at the time of a collision, and an airbag that is stored inside in a folded state, and the airbag is expanded. an airbag case with an opening facing the seated occupant;
An airbag device having an airbag cover disposed in a position to close the opening and having a hinge portion for deployment at one end and a locking portion that breaks when the airbag is deployed at the other end. At the initial stage of deployment, the deployment of the airbag near the central portion of the airbag cover is restricted so that the load associated with the airbag deployment is effectively applied to the vicinity of the locking portion, and the airbag ruptures at least after the locking portion breaks. An airbag device for an automobile, comprising: a deployment regulating means.
本発明にかかるエアバッグ装置は以上のように構成され
、エアバッグ展開初期、エアバッグカバーの中央部近傍
でのエアバッグの展開が規制され。The airbag device according to the present invention is configured as described above, and at the initial stage of airbag deployment, the deployment of the airbag near the center of the airbag cover is restricted.

けることにより槓なわれるということはない。Since the load generated when the airbag is deployed does not act significantly near the central portion of the airbag cover, the load generated when the airbag is deployed is effectively transmitted to the vicinity of the locking portion. Therefore, the locking portion breaks almost simultaneously with the deployment of the airbag, and the airbag cover is deployed without delaying the start of deployment of the airbag. Furthermore, since the restricting means is set to break after the locking portion of the airbag cover is broken, the ability of the airbag to restrain the occupant will not be compromised by providing the deploying restricting means. .
以下１図面に基づき本発明の好適な実施例を説明する。 A preferred embodiment of the present invention will be described below based on one drawing.
尚、従来技術と同一の部位については。In addition, regarding the same parts as the conventional technology.
同一符号を用いて説明する。The explanation will be given using the same reference numerals.

部材３は、その両側端にいわゆるミシン目が形成され、
所定荷重が加えられると破断するよう構成されている。As shown in FIGS. 1 and 2, an airbag 5, an inflator 6, etc. are housed in an airbag case 2. Further, an opening 9 for the airbag 5 to pop out is formed in the airbag case 2. The upper part of the opening 9 for popping out is covered with a cloth-like deployment regulating member 3. In addition, the expansion regulating member 3 has so-called perforations formed at both ends thereof.
It is configured to break when a predetermined load is applied.

ヒンジ部７を軸として展開する。However, since the upper part of the opening 9 is blocked by the deployment regulating member 3, the deployment of the airbag 5 is as shown in FIG. It unfolds near the locking member 4 of the cover 1. Therefore, the load generated when the airbag 5 is deployed acts largely on the vicinity of the locking member 4, and the locking member 4 easily breaks. Also, due to the above load, the airbag cover 1
This prevents the central part from deforming. Therefore, the airbag cover 1 deploys around the hinge portion 7 without delay when the airbag 5 starts deploying.
