    摘要： An air-bag comprising: first and second sheets of fabric; an inlet into which gas will be introduced into the air-bag to inflate the air-bag when the air-bag is deployed; and a first seam which describes or forms part of a loop which encloses or substantially encloses an interior region, so that the interior region is separated from the inlet by at least the first seam, wherein at least one part of the first seam comprises one or more regions at which the first and second sheets of fabric are not joined to one another, to allow gas to flow into the interior region from a region outside the interior region, to allow inflation of the interior region during deployment of the air-bag.

    摘要： An air-bag for a motor vehicle, the air-bag being formed from two superposed layers of fabric, each of the layers being woven from a plurality of yarns, the layers of fabric being connected to each other at least partially through interweaving of the yarns of the two layers with each other, wherein the air-bag comprises: at least one inflatable region, in which the two layers of fabric are substantially not connected to each other, so that gas can be introduced into the space between the two layers to inflate the inflatable region; and at least one non-inflatable region, the non-inflatable region comprising an area over which, for one of the layers of fabric, there is a first number of crossing points of yarns that form the layer of fabric, and there is a second number of connections between the two layers, wherein at each connection a yarn of the layer of fabric extends across to the other layer and passes over the far side of the a yarn of the other layer, and wherein the second number is no more than 0.0033 times the first number.

    摘要翻译： 一种用于机动车辆的气囊，所述气囊由两个重叠的织物层形成，每个层由多根纱线编织，所述织物层至少部分地通过相互连接的方式彼此连接 两层的纱线彼此相对，其中气囊包括：至少一个可充气区域，其中两层织物基本上彼此不连接，使得气体可以被引入到两层之间的空间中 使充气区域膨胀; 和至少一个不可充气区域，所述不可充气区域包括一个区域，对于所述织物层之一，形成所述织物层的第一数量的纱线交叉点，并且存在第二 两层之间的连接数，其中在每个连接处，织物层的纱线横跨另一层延伸并越过另一层的纱线的远侧，并且其中第二数目不大于0.0033 次数第一。
