    • A knee airbag is provided to the lower part of a glove box door, and an airbag door provided to the glove box door opens in both upward and downward directions when the knee airbag expands. As the knee airbag expands, the rigidity of the lower part of the glove box door decreases, and this causes a relatively small reaction force, which corresponds to a relatively small load generated when the knees of an occupant having a relatively small body build make contact with the lower part, to be generated on the lower part of the glove box door. On the other hand, because the knee airbag is not provided to the upper part of the glove box door, the upper part can generate a relatively large reaction force which corresponds to a relatively large load generated when the knees of an occupant having a relatively large body build make contact with the upper part via the knee airbag.
    • 膝盖安全气囊设置在手套箱门的下部,并且当膝部安全气囊膨胀时,设置在手套箱门上的气囊门在向上和向下的方向上打开。 当膝盖气囊膨胀时,手套箱门下部的刚性减小,这导致相对较小的反作用力,这对应于当具有相对较小的身体构造的乘员的膝盖接触时产生的相对较小的负载 下部将在手套箱门的下部产生。 另一方面,由于没有将手套箱门的上部设置膝部安全气囊,所以上部可产生相当大的反作用力,该反作用力相当于当具有较大的乘员的膝盖产生的较大的载荷 身体构造通过膝盖安全气囊与上部接触。

    • A knee airbag device for a vehicle is provided that is capable of effectively protecting both knees of a seat occupant, regardless of position, shape or the like of an airbag door relative to the seat. In a passenger seat knee airbag device, a tear line of an airbag door retainer is broken and airbag doors are deployed upward and downward by deployment force of a knee airbag that receives a gas supply from an inflator. Thus, the knee airbag is deployed toward the knees of the occupant through an aperture portion formed in the airbag door retainer. A tear line of a form that is non-symmetrical between left and right is formed in a retaining sheet that is for retaining the knee airbag in a folded state. Thus, timings of deployment of the airbag doors by inflation pressure of the knee airbag are caused to differ between a left side portion and a right side portion.
    • 提供了一种用于车辆的膝盖安全气囊装置,其能够有效地保护座椅乘员的膝盖,而不管安全气囊门相对于座椅的位置,形状等。 在乘客座椅膝部安全气囊装置中,气囊门保持器的撕裂线被破坏,并且气囊门通过从充气机接收气体供应的膝部安全气囊的展开力向上和向下展开。 因此,膝盖安全气囊通过形成在安全气囊门保持器中的开口部分朝向乘员膝盖展开。 在用于将膝盖气囊保持在折叠状态的保持片中形成左右之间不对称的形式的撕裂线。 因此,在左侧部分和右侧部分之间导致通过膝盖气囊的充气压力展开安全气囊门的时间。
