Description

行人安全气囊和车辆 技术领域
本发明涉及车辆的安全装置，具体地，涉及行人安全气囊，以及，还涉及包括该行人安全气囊的车辆。
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，由充气机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。
考虑到车辆与行人相撞的情况，安全气囊还包括行人安全气囊，以保护行人在与车辆碰撞而倒在机罩板和/或前挡风玻璃上时，为行人提供保护。
但是，现有的行人安全气囊存在保护性能较弱且气袋展开体积较大的特点。
发明内容
本发明的目的是提供一种保护性能较强且气袋展开体积较小的行人安全气囊，以及，还提供一种包括该行人安全气囊的车辆。
本发明的一方面提供一种行人安全气囊，其具有充气机和气袋，所述气袋具有收纳状态和展开状态，当处于收纳状态时，所述气袋被收纳在车辆的机罩板的后部的下方，以及，所述充气机用于对所述气袋进行充气以使其进入展开状态，其中，所述气袋包括流体连通的第一腔室和第二腔室，当处于展开状态时，所述第一腔室和所述第二腔室在所述气袋的厚度方向上重叠，以及，所述第一腔室上设置有不被充气的第一未充气区。
根据本发明的实施例，当处于展开状态时，所述第一腔室具有U形的 形状，以及，多个所述第二腔室沿着所述第一腔室的U形长度方向间隔开。
根据本发明的实施例，多个所述第一未充气区被设置为沿着所述第一腔室的U形长度方向间隔开，并且，每一个所述第一未充气区被设置为沿着所述第一腔室的U形长度方向延伸。
根据本发明的实施例，用于所述充气机的充气口设置在所述气袋的第一侧，并且，所述第一侧上还设置有用于将所述气袋固定到所述机罩板的多个连接部。
根据本发明的实施例，所述第一腔室和所述第二腔室由同一片织物形成。
根据本发明的实施例，在所述气袋的与所述第一侧相对的第二侧处，所述第二腔室与所述第一腔室被构造为一体结构，并且，在所述第二侧处，所述第二腔室的端部与所述第一腔室经由连接件连接。
根据本发明的实施例，所述连接件被构造为缝线。
根据本发明的实施例，每个所述第二腔室上设置有不被充气的第二未充气区。
根据本发明的实施例，所述第一未充气区被构造为骨头状，以及，所述第二未充气区被构造为圆形状。
本发明的另一方面提供一种车辆，其中，包括前挡风玻璃和前述任一项所述的行人安全气囊，当处于展开状态时，所述第二腔室位于所述第一腔室和所述前挡风玻璃之间。
附图说明
下面将参考附图来描述本发明示例性实施例的特征、优点和技术效果。在附图中，相同的符号标示相同的元件，其中：
图1示意性地示出根据本发明实施例的行人安全气囊的制作方法。
图2示意性地示出根据本发明实施例的行人安全气囊。
图3示意性地示出根据本发明实施例的车辆。
具体实施方式
以下将结合附图描述根据本发明的行人安全气囊和车辆的具体实施方式。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，本发明描述的各个实施例既可以单独使用，也可以任意组合，本发明的保护范围由权利要求书限定。
此外，空间相关术语(诸如“上”、“下”、“左”和“右”等)用于描述附图所示的元件与另一个元件的相对位置关系。因此，空间相关术语可以应用到使用时与附图所示的方向不同的方向中。显然，虽然为了易于说明，所有这些空间相关术语指的是附图所示的方向，但是本领域技术人员能够理解可以使用与附图中所示的方向不同的方向。
图1示意性地示出根据本发明实施例的行人安全气囊的制作方法。图2示意性地示出根据本发明实施例的行人安全气囊。以下结合图1和图2描述根据本发明的行人安全气囊。
如图1和图2所示，本发明的行人安全气囊10具有充气机(未示出)和气袋11，气袋11具有收纳状态和展开状态，以及，气袋11上设置有充气口101，经由该充气口101，充气机对气袋11进行充气以使其进入展开状态，该展开状态如图2所示。当处于展开状态时，气袋11用于保护行人。当处于收纳状态时，气袋11将被收纳在车辆1的机罩板的后部的下方。
如图1和图2所示，气袋11包括流体连通的第一腔室100和第二腔室200，在图示的具体示例中，第一腔室100的体积设计为较大且数量为一个，第二腔室200的体积设计为较小且数量为四个，以下详细描述基于该具体示例的气袋11的制造方法。如图1所示，第一腔室100和第二腔室200可以选择为由同一片织物形成。在制造气袋11时，第一步，在该织物上设置切割线C1、C2、C3共三条切割线以及折叠线F1、F2、F3、F4共四条折叠线；第二步，将气袋11沿着切割线C1、C2、C3切割，以获得四个第二腔室200，能够理解，各个第二腔室200与第一腔室100在其较宽侧处仍然一体地连接在一起；第三步，沿着折叠线F1、F2、F3、F4向后折叠各个第二腔室200，并且用缝线将各个第二腔室200的与折叠线相对的一端(较窄侧的端部)连接到第一腔室100，如图2所示。因此，当 处于展开状态时，第一腔室100和第二腔室200在气袋11的厚度方向上重叠。与此同时，第一腔室100上设置有不被充气的第一未充气区102。
因此，在本发明的安全气囊中，当气袋处于展开状态时，在第一腔室和第二腔室重叠的区域处，气袋的厚度较大，这有利于更好地吸收碰撞能量；以及，在第一腔室和第二腔室不重叠的区域处，第一腔室被抬高，从而与前挡风玻璃之间的距离变长，这有利于延长碰撞持续时间，从而减小碰撞加速度，由此更好地吸收碰撞能量。与此同时，第一未充气区的设置有利于减小气袋的厚度，减小气袋的充气量和充气时间，以及，降低对充气机的功率要求。因此，本发明的行人安全气囊具有保护性能较强且气袋展开体积较小的特点。
能够理解，在本发明的行人安全气囊中，气袋的第一腔室和第二腔室不限于由同一片织物形成，例如，第一腔室和第二腔室可以是先由分离的织物制造，并且之后经由例如缝线连接在一起。以及，在本发明的行人安全气囊中，不限于使用缝线连接第一腔室和第二腔室，第一腔室和第二腔室之间的连接件还可以被构造为例如胶。
作为本发明的一个示例，当处于展开状态时，第一腔室100具有U形的形状，当充气机充气时，该第一腔室100从机罩板喷出并且沿着前挡风玻璃的两侧延伸直到车辆的A柱。以及，多个第二腔室200沿着第一腔室100的U形长度方向间隔开，以均匀地支撑第一腔室100。
作为本发明的一个示例，如图1和2所示，多个第一未充气区102被设置为沿着第一腔室100的U形长度方向间隔开，并且，每一个第一未充气区102被设置为沿着第一腔室100的U形长度方向延伸。进一步地，作为本发明的另一个示例，每个第二腔室200上设置有不被充气的第二未充气区201，这有利于进一步减小气袋11的厚度。作为本发明的一个例，所述第一未充气区被构造为骨头状，以及，所述第二未充气区被构造为圆形状，当然，还可以根据需要对第一未充气区和第二未充气区两者的形状进行不同的设计。
作为本发明的一个示例，如图1和2所示，在气袋11的设置有用于充气机的充气口101的一侧，还设置有用于将气袋11固定到机罩板的多个 连接部103。
图3示意性地示出根据本发明实施例的车辆。如图3所示，本发明实施例的车辆1包括前挡风玻璃20和行人安全气囊10，当处于展开状态时，第二腔室200位于第一腔室100和前挡风玻璃20之间。能够理解，以上参照本发明的行人安全气囊描述的优点同样地适用于本发明的车辆，因此这里不再赘述以避免冗余。
对于本发明的行人安全气囊，气袋被充气后的路径较平滑，仅通过行人安全气囊与机罩板之间的固定点即可维持整个气袋的基本位置，而且，第一腔室和第二腔室彼此流体连通，整个气袋的形状能够在恒定的内压下维持预定的姿态而无需在气袋位于A柱的端部另外设置固定部或拉带。
如前所述，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。
