Description
上記の目的を達成するために、請求項１に記載の発明は、エアバッグ装置のエアバッグを乗員側から覆うカバー本体部と、固定部により前記カバー本体部に乗員側から固定される装飾部材とを備え、前記エアバッグの膨張圧が作用することにより破断されるティアラインが設けられたエアバッグ装置用カバーであって、前記ティアラインは、前記カバー本体部にのみ設けられて同カバー本体部を複数の領域に仕切り、前記エアバッグの膨張圧により破断されて、前記領域に対応した複数の扉部を形成するものであり、前記ティアラインの前記カバー本体部における位置が、正面視で前記装飾部材と重なる箇所に設定され、さらに、前記固定部による前記装飾部材の前記カバー本体部に対する固定は、正面視で同装飾部材と重なる領域のうちの１つに対してのみ行われており、前記カバー本体部において、正面視で前記装飾部材と重なる領域のうち前記装飾部材が固定される領域とは異なる領域の少なくとも１つには被係合部が設けられる一方、前記装飾部材において、前記被係合部に対応する箇所には、前記ティアラインの破断前には前記被係合部に係合され、かつ前記ティアラインが破断されて前記扉部が開くときには前記被係合部から外れる係合部が設けられており、前記係合部と被係合部との係合により、前記ティアラインの破断前に前記装飾部材が前記カバー本体部から浮き上がることが防止されていることを要旨とする。 In order to achieve the above object, the invention according to claim 1 is directed to a cover main body that covers an airbag of an airbag device from the occupant side, and a decorative member that is fixed to the cover main body from the occupant side by a fixing portion And a cover for an airbag device provided with a tear line that is broken by the action of inflation pressure of the airbag, wherein the tear line is provided only on the cover body portion. The portion is divided into a plurality of regions, and is broken by the inflation pressure of the airbag to form a plurality of door portions corresponding to the regions, and the position of the tear line in the cover main body portion is a front view. The decorative member is set at a location that overlaps the decorative member, and the fixing portion fixes the decorative member to the cover main body portion in a region overlapping the decorative member in a front view. It has been done only for One, in the cover main body, at least one in the engaged portion of the area different from the area where the decorative member in the region overlapping with the decorative member in a front view is fixed On the other hand, in the decorative member, in the portion corresponding to the engaged portion, the door portion is engaged with the engaged portion before the tear line is broken and the tear line is broken. An engagement portion is provided that is disengaged from the engaged portion when the opening is opened, and the decorative member is detached from the cover main body portion before the tear line breaks due to the engagement between the engagement portion and the engaged portion. The gist is that it is prevented from floating .
また、ティアラインが破断される前、すなわちエアバッグの非膨張時には、装飾部材の係合部がカバー本体部の被係合部に係合している。この係合により、装飾部材において、被係合部の設けられた領域に対応する箇所がカバー本体部に係止されている。このため、装飾部材の上記箇所はカバー本体部との固定箇所から遠ざかっているが、同カバー本体部に接近又は当接した状態に保持され、余程大きな力が加わらない限り、カバー本体部から浮き上がることが起こりにくい。 Further , before the tear line is broken, that is, when the airbag is not inflated, the engaging portion of the decorative member is engaged with the engaged portion of the cover main body portion. By this engagement, a portion of the decorative member corresponding to the region where the engaged portion is provided is locked to the cover main body portion. For this reason, the above-mentioned part of the decorative member is away from the fixed part with the cover main body part, but is kept in a state of approaching or abutting the cover main body part, and from the cover main body part unless a large force is applied. It is difficult to lift.
これに対し、エアバッグが膨張展開すると、上述したようにティアラインに沿ってカバー本体部が破断され、カバー本体部に複数の扉部が形成される。この段階では、装飾部材の係合部はカバー本体部の被係合部に係合し続ける。装飾部材の固定された扉部が、その装飾部材を伴って開く。表現を変えると、装飾部材（係合部を含む）が、上記のように開く扉部に追従して移動する。この移動の途中で、装飾部材の係合部がカバー本体部の被係合部から外れる。従って、扉部の開放時に係合部が被係合部に係合し続けると、その扉部の開放の妨げとなるが、請求項１に記載の発明では、そのような現象が起こらず、扉部は予定したとおりにスムーズに開く。 On the other hand, when the airbag is inflated and deployed, the cover body portion is broken along the tear line as described above, and a plurality of door portions are formed in the cover body portion. At this stage, the engaging portion of the decorative member continues to engage with the engaged portion of the cover main body portion. The door part to which the decorative member is fixed opens together with the decorative member. In other words, the decorative member (including the engaging portion) moves following the door portion that opens as described above. In the middle of this movement, the engaging portion of the decorative member is disengaged from the engaged portion of the cover main body portion. Therefore, if the engaging portion continues to engage with the engaged portion when the door portion is opened, the opening of the door portion is hindered, but in the invention according to claim 1 , such a phenomenon does not occur, The door opens smoothly as planned.
上記係合部及び被係合部としては、例えば請求項２に記載の発明の構成を採用することができる。すなわち、請求項２に記載の発明は、請求項１に記載の発明において、前記被係合部は前記カバー本体部に設けられた孔部により構成され、前記係合部は、前記装飾部材から突出する突起により構成されるものであることを要旨とする。 For example, the configuration of the invention according to claim 2 can be adopted as the engaging portion and the engaged portion. That is, the invention according to claim 2 is the invention according to claim 1 , wherein the engaged portion is configured by a hole provided in the cover main body portion, and the engaging portion is formed from the decorative member. The gist of the invention is that it is constituted by protruding protrusions.
また、上記突起が孔部から抜け出ることにより、係合部が被係合部から外れ、装飾部材のカバー本体部との上記係止が解除される。
上記突起及び孔部としては、例えば請求項３に記載の発明の構成を採用することができる。すなわち、請求項３に記載の発明は、請求項２に記載の発明において、前記カバー本体部には、その乗員側の一般面から前方へ凹んだ段差凹部が設けられ、前記段差凹部には、前記装飾部材が、その外側面を同段差凹部の内側壁に接近させられた状態で配置されており、前記孔部は前記段差凹部の前記内側壁に設けられ、前記突起は前記装飾部材の前記外側面に設けられていることを要旨とする。
Further, when the protrusion is pulled out from the hole portion, the engaging portion is detached from the engaged portion, and the locking of the decorative member with the cover main body portion is released.
As the protrusion and the hole, for example, the configuration of the invention described in claim 3 can be adopted. That is, the invention according to claim 3 is the invention according to claim 2 , wherein the cover main body is provided with a step recess recessed forward from a general surface on the passenger side, The decorative member is disposed in a state in which an outer surface thereof is brought close to an inner wall of the stepped recess, the hole is provided on the inner wall of the stepped recess, and the protrusion is the protrusion of the decorative member. The gist is that it is provided on the outer surface.
