Title (EN) AIRBAG
(FR) COUSSIN DE SÉCURITÉ GONFLABLE
(JA) エアバッグ
Abstract:
(EN) Provided is an airbag which further reduces the degree of injury to a vehicle occupant while also exhibiting sufficient occupant protection performance using less output from the inflator, by both preventing airbag internal pressure from rising excessively when making contact with the occupant and increasing the speed of deployment in an occupant-protection area. This hollow-weave airbag has an opening in a main chamber that inflates for the purpose of occupant protection, a structure wherein a first yarn extending separatingly from a first fabric layer of the opening to a non-inflating portion is caught on a float yarn extending on the inside of a second fabric layer and subsequently caught on a float yarn extending on the inside of the first fabric layer, this structure being repeated at least once and forming a pair with another structure wherein a second yarn extending separatingly from the second fabric layer of the opening to the non-inflating portion is caught on the float yarn extending on the inside of the first fabric layer and subsequently caught on the float yarn extending on the inside of the second fabric layer, this structure being repeated at least once.
(FR) Coussin de sécurité gonflable qui réduit en outre le degré de blessure d'un occupant de véhicule tout en présentant également une performance de protection d'occupant suffisante en utilisant une moindre sortie du dispositif de gonflage, en empêchant la pression interne du coussin de sécurité gonflable de trop monter lors du contact avec l'occupant et en augmentant la vitesse de déploiement dans une zone de protection de l'occupant. Ce coussin de sécurité gonflable d'armure creuse comporte une ouverture dans une chambre principale qui se gonfle dans le but de protéger l'occupant, une structure dans laquelle un premier fil s'étendant de manière séparée d'une première couche de tissu de l'ouverture vers une partie de non-gonflage est coincé sur un fil flottant s'étendant sur l'intérieur d'une seconde couche de tissu et ensuite coincé sur un fil flottant s'étendant sur l'intérieur de la première couche de tissu, cette structure étant répétée au moins une fois et formant une paire avec une autre structure, un second fil s'étendant de manière séparée de la seconde couche de tissu de l'ouverture vers la partie de non-gonflage étant coincé sur le fil flottant s'étendant sur l'intérieur de la première couche de tissu et ensuite coincé sur le fil flottant s'étendant sur l'intérieur de la seconde couche de tissu, cette structure étant répétée au moins une fois.
(JA) 乗員保護エリアの展開速度を高速にしつつ、乗員当接時のエアバッグの過度な内圧上昇を抑えることで、乗員への障害値をより低減しつつ、より少ないインフレーターの出力で十分な乗員保護性能を有するエアバッグを提供する。本発明の袋織エアバッグは、乗員保護を目的として膨張する主室に開口部を持ち、開口部の第1の布層から離れて非膨張部まで延在する第1糸条が、第2の布層の内側に延在する浮糸に引っ掛かった後、第1の布層の内側に延在する浮糸に引っ掛かる構造を少なくとも1回以上繰り返し、それと対をなすように、第2の布層から離れて非膨張部まで延在する第2糸条が、第1の布層の内側に延在する浮糸に引っ掛かった後、第2の布層に延在する浮糸に引っ掛かる構造を少なくとも1回以上繰り返す構造を持つ。
