Description

本発明は、車体天井部に配設されたエアバッグと、側面衝突時に高圧ガスを発生させて前記エアバッグを乗員と車体側部との間で展開するように膨張させるインフレータとを備えた自動車のエアバッグ装置に関し、詳細にはエアバッグに沿って電装ケーブルを配設する場合の構造に関する。   The present invention provides an automobile comprising an airbag disposed on a vehicle body ceiling, and an inflator that generates high-pressure gas at the time of a side collision and inflates the airbag to be deployed between an occupant and a vehicle body side. In detail, the present invention relates to a structure in the case of disposing an electrical cable along the airbag.

自動車においては、側面衝突時の乗員の保護性能を高める観点から、カーテンシールドエアバッグ装置を搭載する場合がある。この種のエアバッグ装置では、エアバッグを折り畳んだ状態で車体天井部に車両前後方向に延びるように配設し、側面衝突時にインフレータにより高圧ガスを噴出して前記エアバッグを乗員と車体側部との間で展開，膨張させるようにしている。   In automobiles, a curtain shield airbag device may be mounted from the viewpoint of improving the protection performance of an occupant during a side collision. In this type of airbag device, the airbag is folded so as to extend in the vehicle front-rear direction in the vehicle body ceiling, and high-pressure gas is blown out by an inflator at the time of a side collision so that the airbag is It expands and expands between.

また前記自動車では、前記エアバッグに沿ってラジオアンテナケーブル等の電装ケーブルを配設することにより、エアバッグと電装ケーブルとを一体化して天井部に格納する場合がある。この場合、電装ケーブルがエアバッグの展開の妨げにならないように配設する必要がある。このため、例えば、特許文献１には、エアバッグを車体に取り付けるためのカバー部材の外側壁に、複数のホルダを介して電装ケーブルを固定するようにしたものが提案されている。   Moreover, in the said motor vehicle, by arrange | positioning electrical equipment cables, such as a radio antenna cable, along the said airbag, an airbag and an electrical equipment cable may be integrated and stored in a ceiling part. In this case, it is necessary to arrange the electrical cable so as not to hinder the deployment of the airbag. For this reason, for example, Patent Document 1 proposes a configuration in which an electrical cable is fixed to an outer wall of a cover member for attaching an airbag to a vehicle body via a plurality of holders.

特開２００８−１７９２７３号公報JP 2008-179273 A

ところで、前記従来のように、電装ケーブルをホルダによりカバー部材の外側壁に固定する場合には、エアバッグの展開の妨げにはならないものの、電装ケーブルの絶縁皮膜を充分に厚くする必要があり、それだけ電装ケーブルが太くなってエアバッグ全体が大型化するという問題がある。即ち、電装ケーブルが車両振動等により車体等に接触して絶縁皮膜が磨耗し、場合によっては電線が露出するおそれがある。このような電線の露出を防止するために、絶縁皮膜を厚くすることとなる。このため、他の電装ケーブル，例えばテレビ，ナビゲーション，あるいはエアバッグ等の各信号ケーブルは別経路を通す必要があり、多極化に対応できないという問題がある。   By the way, as in the conventional case, when fixing the electrical cable to the outer wall of the cover member by the holder, although it does not hinder the deployment of the airbag, it is necessary to sufficiently thicken the insulation film of the electrical cable, There is a problem that the electrical cable becomes thicker and the entire airbag becomes larger. That is, the electrical cable contacts the vehicle body due to vehicle vibration or the like, and the insulating film is worn, and in some cases, the electric wire may be exposed. In order to prevent such exposure of the electric wire, the insulating film is thickened. For this reason, there is a problem that other electric cables, for example, each signal cable such as a television, a navigation, or an air bag, need to be routed through different paths and cannot cope with multipolarization.

本発明は、前記従来の実情に鑑みてされたもので、エアバッグの展開の妨げになることなく、電装ケーブルの細線化を可能にして多極化に対応できる自動車のエアバッグ装置を提供することを課題としている。   The present invention has been made in view of the above-described conventional situation, and provides an automobile airbag device that can reduce the number of electrical cables and cope with multipolarization without obstructing the deployment of the airbag. It is an issue.

請求項１の発明は、車体天井部の、乗員と車体側部との間を臨む部位に配設されたエアバッグと、高圧ガスを発生させるインフレータとを備え、側面衝突時に前記エアバッグを乗員と車体側部との間で展開させるようにした自動車のエアバッグ装置であって、前記エアバッグは、前記高圧ガスにより展開する展開部と、該展開部の展開方向を規制する展開方向規制部とを有し、前記車体天井部には前記エアバッグに沿うように電装ケーブルが配設され、該電装ケーブルは、前記エアバッグの前記展開部と展開方向規制部との間に挟まれた状態で保持されていることを特徴としている。   According to a first aspect of the present invention, there is provided an airbag disposed at a portion of a vehicle body ceiling portion facing between an occupant and a vehicle body side portion and an inflator that generates high-pressure gas, and the airbag is occupant during a side collision An airbag apparatus for an automobile that is deployed between a vehicle body side portion and a vehicle body side portion, wherein the airbag includes a deployment portion that is deployed by the high-pressure gas and a deployment direction regulating portion that regulates a deployment direction of the deployment portion. An electrical cable is disposed along the airbag at the vehicle body ceiling, and the electrical cable is sandwiched between the deployed portion and the deployment direction restricting portion of the airbag. It is characterized by being held by.

本発明に係るエアバッグ装置によれば、エアバッグを展開部と該展開部の展開方向を規制する展開方向規制部とを有するものとし、電装ケーブルを展開方向規制部と展開部との間に挟み込んだ状態で保持したので、電装ケーブルを、エアバッグの展開の妨げになることなく、該エアバッグ内に一体に組み込むことができ、電装ケーブルの車体との接触による磨耗を防止できる。その結果、電装ケーブルの絶縁皮膜を薄くすることができ、それだけ細線化が可能となり、他の電装ケーブルとまとめて配設できる。   According to the airbag device of the present invention, the airbag includes the deployment portion and the deployment direction regulation portion that regulates the deployment direction of the deployment portion, and the electrical cable is disposed between the deployment direction regulation portion and the deployment portion. Since the electric cable is held in a sandwiched state, the electric cable can be integrated into the air bag without hindering the deployment of the air bag, and wear due to contact of the electric cable with the vehicle body can be prevented. As a result, the insulation coating of the electrical cable can be made thinner, and the wire can be made thinner accordingly, and can be arranged together with other electrical cables.

また細線化した電装ケーブルをエアバッグの展開方向規制部と展開部との間に挟み込む構造であるので、従来のエアバッグのカバー部材の外側に太い電装ケーブルを配置する場合に比べて、電装ケーブルを含めたエアバッグ全体をコンパクトにできる。   In addition, since the thinned electrical cable is sandwiched between the deployment direction restricting portion and the deployment portion of the airbag, the electrical cable is larger than the case where a thick electrical cable is disposed outside the cover member of the conventional airbag. The entire airbag including the can be made compact.

It is formed in a length over the entire length in the direction. Thereby, the expansion | deployment part 3a is surrounded by the expansion | deployment direction control part 3b and the inner rail 13b, and only expansion | deployment and expansion | swelling below are permitted.

そして前記アンテナケーブル１６は、前記エアバッグ３の展開方向規制部３ｂと展開部３ａとの間に挟まれた状態で保持されている。また前記エアバッグ信号ケーブル１８は、アンテナケーブル１６とともに展開方向規制部３ｂと展開部３ａとの間に挟まれた状態で一体に保持されている。これにより前記アンテナケーブル１６及びエアバッグ信号ケーブル１８は、エアバッグ３内にこれの全長に渡って収納されている。   And the said antenna cable 16 is hold | maintained in the state pinched | interposed between the expansion | deployment direction control part 3b of the said airbag 3, and the expansion | deployment part 3a. The airbag signal cable 18 is held integrally with the antenna cable 16 while being sandwiched between the deployment direction restricting portion 3b and the deployment portion 3a. Thus, the antenna cable 16 and the airbag signal cable 18 are accommodated in the airbag 3 over the entire length thereof.

前記展開方向規制部３ｂには凸状に膨出する収容部３ｄが形成されており、該収容部３ｄ内にアンテナケーブル１６，エアバッグ信号ケーブル１８が収容配置されている。これらのケーブル１６，１８は、エアバッグ３をロール状に折り畳む際に一体化に組付けられたものである。   A housing portion 3d that bulges in a convex shape is formed in the deployment direction restricting portion 3b, and an antenna cable 16 and an airbag signal cable 18 are housed in the housing portion 3d.

前記エアバッグ装置１は、エアバッグ３にインフレータ４を組み付けるとともに、該エアバッグ３を巻き込んで折り畳む際にアンテナケーブル１６及びエアバッグ信号ケーブル１８を内装し、該各ケーブル１６，１８に前，後中継コネクタ２３，２４を接続することにより製造されたものである。このエアバッグアッシィを車体２に搭載し、エアバッグ３を天井部２ａに組み付けるとともに、各ケーブル１６，１８をラジオ１１，ＥＣＵ５に接続する。   The air bag device 1 assembles the inflator 4 to the air bag 3 and incorporates an antenna cable 16 and an air bag signal cable 18 when the air bag 3 is wrapped and folded. It is manufactured by connecting the relay connectors 23 and 24. The airbag assembly is mounted on the vehicle body 2, the airbag 3 is assembled to the ceiling 2 a, and the cables 16 and 18 are connected to the radio 11 and the ECU 5.

本実施例によれば、エアバッグ３を展開部３ａと該展開部３ａの展開方向を規制する展開方向規制部３ｂとを有するものとし、アンテナケーブル１６及びエアバッグ信号ケーブル１８を展開方向規制部３ｂと展開部３ａとの間に挟み込んだ状態で保持したので、エアバッグ３の展開の妨げになることなく、前記各ケーブル１６，１８をエアバッグ３内に一体に組み込むことができ、アンテナケーブル１６，エアバッグ信号ケーブル１８の磨耗を防止できる。その結果、アンテナケーブル１６，エアバッグ信号ケーブル１８の絶縁皮膜を薄くすることができ、それだけ細線化が可能となり、多極化に対応できる。例えば、テレビやナビゲーションシステムの受信ケーブル，あるいはコンビネーションリヤランプ等の配線ケーブルをエアバッグ３にまとめて配設することが可能となる。   According to the present embodiment, the airbag 3 includes the deploying portion 3a and the deploying direction restricting portion 3b that restricts the deploying direction of the deploying portion 3a, and the antenna cable 16 and the airbag signal cable 18 are connected to the deploying direction restricting portion. Since it is held in a state of being sandwiched between 3b and the deployment portion 3a, the cables 16 and 18 can be integrated into the airbag 3 without interfering with the deployment of the airbag 3, and the antenna cable 16. Wear of the airbag signal cable 18 can be prevented. As a result, the insulating coatings of the antenna cable 16 and the air bag signal cable 18 can be made thin, and it is possible to make the wires thinner, and it is possible to cope with multipolarization. For example, a receiving cable for a television or a navigation system, or a wiring cable such as a combination rear lamp can be collectively arranged in the airbag 3.

また細線化した各ケーブル１６，１８をエアバッグ３の展開方向規制部３ｂと展開部３ａとの間に挟み込む構造であるので、従来のエアバッグのカバー部材の外側に太い電装ケーブルを配置する場合に比べてエアバッグ全体をコンパクトにできる。   In addition, since the thinned cables 16 and 18 are sandwiched between the deployment direction regulating portion 3b and the deployment portion 3a of the airbag 3, a thick electrical cable is disposed outside the cover member of the conventional airbag. Compared with, the entire airbag can be made compact.

前記各ケーブル１６，１８をフロントピラー８に沿って配索することができるので、配索経路を簡素化できる。即ち、従来は、フロントピラーに太いアンテナケーブルを配索することから、エアバッグ信号ケーブルは別経路のセンターピラーに配索しており、経路が複雑となるとともに、組み付け性が低いという問題があった。   Since the cables 16 and 18 can be routed along the front pillar 8, the routing route can be simplified. That is, conventionally, since a thick antenna cable is routed in the front pillar, the airbag signal cable is routed in the center pillar of another route, which causes a problem that the route becomes complicated and the assembly property is low. It was.

本実施例では、エアバッグ３の搭載レイアウトがそのままアンテナケーブル１６，エアバッグ信号ケーブル１８の配索経路となるので、各ケーブル１６，１８の配置経路に関する調整が不要となる。また各ケーブル１６，１８の組み付けが不要となる分、組み立て工数を低減できるとともに、組み立て作業を容易にできる。   In the present embodiment, since the mounting layout of the airbag 3 becomes the routing route of the antenna cable 16 and the airbag signal cable 18 as it is, adjustment regarding the routing route of the cables 16 and 18 becomes unnecessary. Further, since the assembly of the cables 16 and 18 becomes unnecessary, the number of assembling steps can be reduced and the assembling work can be facilitated.
