附图说明
参照附图，本发明的公开内容将变得更易理解。本领域技术人员容易理解的是：这些附图仅仅用于说明的目的，而并非意在对本发明的保护范围构成限制。此外，图中类似的数字用以表示类似的部件，其中：
图1示出了车辆内部的安全气囊在展开状态下的视图；以及
图2示出了单独的安全气囊在展开状态下的视图。
具体实施方式
容易理解，根据本发明的技术方案，在不变更本发明实质精神下，本领域的一般技术人员可以提出可相互替换的多种结构方式以及实现方式。因此，以下具体实施方式以及附图仅是对本发明的技术方案的示例性说明，而不应当视为本发明的全部或者视为对本发明技术方案的限定或限制。
在本说明书中提到或者可能提到的上、下、左、右、前、后、正面、背面、顶部、底部等方位用语是相对于各附图中所示的构造进行定义的，它们是相对的 概念，因此有可能会根据其所处不同位置、不同使用状态而进行相应地变化。所以，也不应当将这些或者其他的方位用语解释为限制性用语。
图1示出了副驾驶座位处车内示意图，其中安全气囊3处于展开状态。应当理解，安全气囊3在收缩状态下容置于车辆前挡风玻璃的顶梁1处，在具有天窗7的车型中，安全气囊3容置于前挡风玻璃的顶梁1和天窗7之间。在一些实施例中，安全气囊3在被触发后从上向下地快速展开，为乘客提供缓冲。在一些实施例中，安全气囊3在收缩位置时容置于遮阳板2背后，在展开过程中，安全气囊推开遮阳板2并从遮阳板2与前挡风玻璃顶梁1之间的缝隙迅速窜出，并展开成如图1所示的展开状态。在该展开状态下，安全气囊3处于仪表板4(以及前挡风玻璃)和坐在座椅5上的乘客6之间，起到缓冲作用，防止乘客与前挡风玻璃直接撞击。应当理解，尽管本发明的实施例针对用于副驾驶的安全气囊来描述，但根据本发明的实施例的安全气囊不限于用于车辆副驾驶，其同样可用于车辆上其他适合的位置。
如图2所示，安全气囊3具有主气袋31，主气袋31在展开状态下在沿纵向截面中呈水滴形。所谓纵向截面指沿车辆前后方向的竖直截面。所谓水滴形指类似于水滴等液体在重力下所呈的自然形态的形状，更具体地，水滴形包括较尖的顶部和接近圆形的底部。根据本申请的实施例的安全气囊3的主气袋31在展开后的形状同样具有尖的顶部301和大致呈(半)圆形的底部302，其中主气袋31的尖的顶部301具有渐扩的形状，这有利于气体迅速扩散并填充安全气囊的主气袋31，圆弧形底部302可提供良好的缓冲，较好地保护乘客。在一些实施例中，安全气囊3还包括扁平的导气袋32。导气袋32可具有扁平的形状。所谓扁平形状指导气袋32的宽度W远大于其厚度T，例如导气袋32的宽度W可为其厚度T的5倍以上，甚至10倍以上等。导气袋32设置在气体发生器(未示出)与主气袋31之间，其具有用于与气体发生器连接的第一端321以及用于与主气袋31连接的第二端322。在一些实施例中，如图2所示，导气袋32的形状形成为扁平矩形形状。在一些实施例中，在气囊展开时，导气袋32正好位于遮阳板2与前挡风玻璃顶梁1之间的间隙处，其扁平的形状可在无须遮阳板过多打开时，允许气体通过来对主气袋充气，使得安全气囊能够迅速地展开。所谓“矩形形状”指导 气袋32在与气流方向垂直的纵截面中基本呈矩形(忽略导气袋32在气体压力下的弹性变形)。在一些实施例中，导气袋32在各个所述纵截面中具有基本相同的厚度T，在一些实施例中，导气袋32的厚度T沿气流方向从第一端321向第二端322逐渐增大。在一些实施例中，导气袋32的宽度W保持一致，并等于安全气囊3的主气袋31的宽度。在一些实施例中，主气袋31与导气袋32是一体成型。在备选实施例中，也可采用单独的导气袋32，并将导气袋32缝接至主气袋31。
在一些实施例中，安全气囊3可由三片片材接合而成，更具体地，由主片34和主片34两侧的两个侧片35，36接合形成。在一些实施例中，主片34与两个侧片35,36缝合在一起。在一些实施例中，两个侧片35，36可形成为水滴形并具有对应于导气袋的窄条323，主片34在未接合前平铺时可为矩形片材。呈矩形的主片34的两侧的长边分别与两个侧片35,36接合，如通过缝合来气密地彼此接合，由此形成了根据发明的实施例的安全气囊3。所获得的安全气囊3在展开状态型呈对应于侧片35，36形状的正柱形形状(忽略由于充气导致的安全气囊的弹性变形)。所谓正柱形形状指具有由两个侧片限定的相互平行的两个平面，以及由主片34限定的连接在两个平行平面之间并垂直于两个平行平面的侧面。在一些实施例中，在两个侧片35,36中的一者或两者上可形成有放气口33，在气囊展开时可通过放气口33来将气囊中的气体泄放，以便乘客可安全离开座位。
在一些实施例中，安全气囊3的主气袋31可具有呈弧形平缓过渡的背侧311，所谓安全气囊的背侧为背对座位上乘客的一侧。平缓过渡的背侧311有利于引导气流快速填充安全气囊3。相对地，在安全气囊3的主气袋31前侧(面向乘客的一侧)具有平直的过渡段313，随后主气袋31从平直过渡段313向下延伸，其从平直过渡段313的延伸平面313'向前(乘客方向)隆起，以具有隆起部分317。如图1所示，该隆起部分317对应于乘客的颈部以下，如胸部或腹部(统称胸腹部)，而在该隆起部分317的上方，对应于乘客头部的位置，安全气囊与乘客间隔开，不会撞击到乘客的头部。
根据本发明的安全气囊3采用顶置布置方式，释放仪表板空间，提供更大的副驾驶乘客空间，提高乘客舒适性。另一方面，根据本发明的安全气囊能够快速展开，导气袋的设计使得在遮阳板稍微打开时气体即能快速填充主气袋，主气 袋特殊水滴形状，符合空气动力学原理，使空气能够迅速填充主气袋。另一方面，根据本发明的安全气囊可由三片片材缝合而成，其结构简单，制造方便，成本低。
根据一些实施例中，还提供了一种安全气囊系统，包括控制器、安全气囊传感器，以及根据本发明各个实施例所述的安全气囊3，所述控制器在接收到所述安全气囊传感器的信号时触发所述安全气囊。
根据一些实施例中，还提供了一种汽车，该汽车配置了根据本发明的各个实施例的安全气囊3。在一些实施例中，安全气囊3配置为副驾驶安全气囊。
以上所描述的具体实施例仅为了更清楚地描述本发明的原理，其中清楚地示出或描述了各个部件而使本发明的原理更容易理解。在不脱离本发明的范围的情况下，本领域的技术人员可容易地对本发明进行各种修改或变化。故应当理解的是，这些修改或者变化均应包含在本发明的专利保护范围之内。
