Abstract

本发明涉及的气袋有一个充气口(12)和一个织物件(16)，布置在气袋(10)里面，对着充气口(12)，该织物件与气袋(10)内表面部分一起，构成压缩空气经过充气口(12)进入气袋(10)的流道。

Description

气袋
本发明涉及的气袋用于汽车乘员保护***。这种保护***包括一个作为主件的装置和一个气袋，前者在起动后供给压缩气体，后者在车祸时，用压缩气体从折叠中和或静止状态开始张开，从而对汽车乘员起到保护作用。
本发明提出的气袋有一个充气口和一个织物件，布置在气袋里面，对着充气口，该织物件与气袋内表面部分合在一起，构成压缩气体通过充气口进入气袋的流道。通过这种流道，气袋可在各个方面张开使用，满足实际需要，同时防止热压缩气体直接碰在气袋壁上，将其损坏。
本发明另一优良结构在相关的权利要求书中详细说明。
本发明参照图中所示最佳实施例予以描述。
图1是按照本发明最佳实施例用图表示的气袋部分平面图。
图2是图1所示气袋部分用图表示的剖面图。
图3是图1描述的气袋部分用图表示的透视图。
从图1～图3中，读者通过图形看到本发明最佳实施例气袋部分图。气袋10设有充气口12，此外还有一个支板14，布置在气袋里面，该支板环绕充气口12。使用支板14可将气袋10连在一个需要供给压缩气体的装置(无图示)上。通过压缩气体，气袋10可从气袋折叠的静止状态(无图示)开始张开。气袋10在张开状态对汽车乘员起到保护作用。这种压缩气体供给装置可以是气体发生器，也可以是压缩气体贮存装置。
气袋10里面，布置一个织物件16，对着充气口12，连在气袋10的壁上，从而在某种意义上与气袋10内表面部分一起，构成一个压缩空气流道，通过充气口12流入气袋10。在插图实施例中，织物件16有4个角，通过其中3个纵向边上的接缝18连在气袋10的壁上。根据无图示的一个方案、织物件16可置于支板14的后面。
由于布置接缝18，织物件16与气袋10的壁和支板14一起形成一个袋，限定流道向气袋内部空间膨胀(特别见图2)，通过充气口12进入气袋10的压缩气体在该流道转向，织物件16的特殊布置使压缩气体向内气流方向，按箭头F所示进入气袋10里面，这样帮助气袋10有控制的张开。
充气口12和另外的织物件16相对于支板14中间偏心布置，流道通向支板16那边，它相对于支板16中间，对着充气口12。由于压缩气体进入气袋10内部时流道的偏移作用，充气口12的这种偏心布置确保气袋10的壁得到保护，不与进入气袋10内部的热腐蚀性压缩空气直接接触。
制造织物件16所用织物与气袋10本身所用的一样。根据特殊用途，织物件可以是单层，也可以是多层。织物件16不得妨碍气袋10折叠，因为折叠可以节省空间。
所以，本发明提出的气袋生产简单，在这种情况下，织物件16合适的设计可以理想的方式作用张开的动作。另外，织物件16保护气袋，10的壁不与在起动时流入气袋内部的热压缩气体直接接触。
