To provide an airbag for a front passenger seat, capable of effectively suppressing projection of a side wall part in a wide range by using two tethers bonded to the side wall part.SOLUTION: An airbag for a front passenger seat is formed so as to project to a vehicle rear side from a storage portion at the inflow of expansion gas, and to be deployed and inflated to protect an occupant, and suppresses a quantity of projection of binding sites 31, 35 of tethers at the completion of inflation by the tethers 50, 54 whose tips are bonded to a side wall part 29, inside the side wall part in a left-right direction in an outer peripheral wall at the completion of inflation. The two tethers 50, 54 are arranged at both end sides with separated parts 33, 37 separated from approach parts 32, 36 approaching each other, as the binding sites 31, 35 to the side wall part 29 at tip sides. The two tether approach parts 32, 36 are separately arranged in a portion of the side wall part therebetween so as to generate a wrinkle part 39 recessed to an inner peripheral side at the completion of inflation of the airbag 15.SELECTED DRAWING: Figure 4
【課題】側壁部に結合される二つのテザーを利用して、効率的に、広い範囲で、側壁部の突出を抑制できる助手席用エアバッグを提供すること。【解決手段】膨張用ガスの流入時に、収納部位から車両後方側に突出して、乗員を保護可能に展開膨張する構成とするとともに、膨張完了時の外周壁における左右方向の側壁部の内部に、先端を側壁部29に結合させたテザー50,54により、膨張完了時のテザーの結合部位31,35の突出量を抑制する。二つのテザー50,51は、先端側における側壁部29への結合部位31,35として、相互に接近する接近部32,36と相互に離隔する離隔部33,37とを、それぞれ、両端側に配設させる。二つのテザーの接近部32,36は、相互の間の側壁部の部位に、エアバッグ15の膨張完了時に内周側に凹むシワ部39を発生させるように、相互に離隔して、配設されている。【選択図】図4
