Description

安全气囊和安全气囊组件 技术领域
本发明涉及车辆的安全装置，具体地，涉及安全气囊和安全气囊组件。
背景技术
在车辆中，普遍使用安全气囊装置以在紧急状况下保护车内乘员免受损伤。安全气囊装置包括安全气囊和气体发生器。安全气囊一般处于收纳状态，并且只有当车辆发生碰撞或受到冲击时才展开。在车辆发生碰撞或受到冲击时，由气体发生器通过爆破产生的气体将使处于收纳状态的安全气囊迅速充气，充气后的安全气囊发生膨胀从而为车辆的乘员提供保护。
然而，处于膨胀展开状态的安全气囊在保护乘员时，可能由于自身受到的支撑力不够而被乘员撞击而脱离其工作位置。在这种情形下，存在无法保护乘员、甚至伤害其他乘员的风险，从而不利地影响安全气囊的可靠工作以及安全性。
因此，期望一种可靠性高且安全性高的安全气囊。
发明内容

根据本发明的实施例，所述限位机构的所述容纳腔被构造为沿着所述左面板的外边缘延伸。
根据本发明的实施例，所述容纳腔被构造为当所述气袋处于展开状态时，从所述气袋的所述左面板的顶部处开始延伸直到距所述左面板的底部一段距离处终止。
根据本发明的实施例，所述拉带的一端被构造为固定到所处驾驶员座椅的所述框架的前侧，并且，所述拉带的另一端被构造为固定到所述驾驶员座椅的所述框架的后侧。
根据本发明的实施例，所述拉带的两端被构造为固定在所述驾驶员座椅的所述框架上时在高度方向上隔开一段距离。

根据本发明的实施例，所述拉带的两端分别设置有具有通孔的安装架，并且，所述安装架经由螺栓分别将所述拉带的两端固定到所述驾驶员座椅的所述框架上。
附图说明
图1示出根据本发明实施例的安全气囊。
图2示出根据本发明实施例的安全气囊组件。
具体实施方式
以下将结合附图描述根据本发明的安全气囊和安全气囊组件的具体实施方式。下面的详细描述和附图用于示例性地说明本发明的原理，本发明不限于所描述的优选实施例，本发明的保护范围由权利要求书限定。
图1示出根据本发明实施例的安全气囊。以下参照图1描述根据本发明实施例的安全气囊。
如图1所示，根据本发明实施例的安全气囊10包括气袋110和限位机构120。气袋110具有展开状态和收纳状态，并且为了清楚地示出限位机构120，图1示出的气袋110处于展开状态。限位机构120布置在气袋110的外侧，具体地，限位机构120包括容纳腔1202和拉带1201，容纳腔1202设置在气袋110的外表面，并且被构造为在气袋110的一个面板上延伸的通道；以及，拉带1201被构造为穿过容纳腔1202，并且能够在容纳腔1202中自由地移动。限位机构120被构造为用于对展开状态下的气袋110的位置进行限制，这将在下文参照图2进行详细描述。
图2示出根据本发明实施例的安全气囊组件。以下参照图2描述根据本发明实施例的安全气囊组件。
如图2所示，根据本发明实施例的安全气囊组件100包括图1中示出的安全气囊10和驾驶员座椅20，并且，安全气囊10被布置在驾驶员座椅20的右侧。需要说明的是，在描述本发明的安全气囊组件时，与安全气囊组件及其部件相关的前方、后方、左侧和右侧分别与安装安全气囊组件的车辆的前方、后方、左侧和右侧相一致。
继续参照图2，安全气囊装置10的限位机构120的拉带1201被构造为两端分别固定到驾驶员座椅20的框架上。一个示例可以是，拉带的一端被构造为固定到驾驶员座椅的框架的前侧，并且，拉带的另一端被构造为固定到驾驶员座椅的框架的后侧。以及，拉带的两端分别设置有具有通孔的安装架，并且，安装架经由螺栓分别将拉带的两端固定到驾驶员座椅的框架上，使得拉带的两端被设置为以可拆卸的方式固定到驾驶员座椅的框架。但是，本发明的安全气囊组件不限于以上示例，本领域技术人员可以根据实际工况，将拉带的两端设置为永久地固定到驾驶员座椅的框架， 以及，可以将拉带的两端固定到驾驶员座椅的框架的同一侧(同在框架的前侧或同在框架的后侧)。
继续参照图2，气袋110在展开状态下具有左面板、右面板和连接左面板和右面板的中间面板，其中，左面板相较于右面板更靠近驾驶员，并且，限位机构120的容纳腔1202位于左面板上。在图2示出的实施例中，限位机构120的容纳腔1202被构造为沿着左面板的外边缘延伸，以使拉带1201尽可能大范围地在气袋110的左面板上施加力。此外，容纳腔1202被构造为当气袋110处于展开状态时，从气袋110的左面板的顶部处开始延伸直到距左面板的底部一段距离处终止，以助于气袋110尽可能大面积地贴靠驾驶员。而且，拉带1201的两端被构造为固定在驾驶员座椅20的框架上时在高度方向上隔开一段距离，从而有效地限定气袋110的位置。
因此，在本发明的安全气囊和安全气囊组件中，在安全气囊的气袋处于膨胀展开状态下，当气袋被乘员撞击时，例如，图2中驾驶员座椅20上的驾驶员向右撞击气袋10时，由于在安全气囊的气袋的外侧设置限位机构，限位机构的拉带通过容纳腔向气袋施加向左的拉力，使得气袋受到足够的支撑而不会被驾驶员向右撞击而脱离其工作位置、甚至撞击到前排右侧乘客。因此，本发明的安全气囊和安全气囊组件能够实现安全气囊在展开状态下限制气袋的位置的目的，从而避免现有技术中安全气囊及安全气囊组件存在无法保护乘员、甚至伤害其他乘员的风险，具有可靠性高且安全性高的优点。
尽管在图1和图2示出的实施例中，容纳腔被示出沿着气袋的左面板的外边缘连续地延伸，但是，这仅仅是示例，并且，本发明的安全气囊不限于此。例如，本领域技术人员可以根据实际工况，将限位机构的容纳腔设置为在气袋的左面板上间断延伸的多个部段；又例如，本领域技术人员可以根据实际工况，将限位机构的容纳腔设置为在气袋的左面板和中间面板两者上延伸。
此外，尽管图2中示出了本发明的安全气囊在前排中央安全气囊中的应用场景，但是这仅仅是示例。本发明的安全气囊还可以用于全包裹式气 囊，在这种情形下，限位机构的容纳腔被设置为在全包裹式气囊的气袋的内侧面上延伸以围绕乘员，从而在该乘员向外撞击气袋时，限位机构的拉带通过容纳腔向气袋施加向内的拉力，使得气袋受到足够的支撑而不会被驾驶员向外撞击而脱离其工作位置。进一步地，本发明的安全气囊还可以用在驾驶员安全气囊、乘员安全气囊和膝部安全气囊的场景中，将本发明的安全气囊的限位机构布置在上述类型的安全气囊的气袋的外侧，以为处于展开状态下的气袋提供与其受到的撞击力的方向相反的支撑力，由此限制气袋的位置，使得以上类型的安全气囊的气袋受到足够的支撑而不会由于受到撞击而脱离其工作位置。
如前，尽管说明中已经参考附图对本发明的示例性实施例进行了说明，但是本发明不限于上述具体实施方式，本发明的保护范围应当由权利要求书及其等同含义来限定。
