背景技术
在车辆中，用于保护后座乘客的安全气囊通常安装在前排座椅的靠背处，其结构形成为圆形气囊结构，存在如下问题：
圆形气囊结构仅能保护后座乘客应对正面冲击；而车辆碰撞时，由于撞击或者驾驶员打方向盘的操作，经常会产生一些小角度的转动，这种转动会带动后座乘客的头部相应偏转至圆形气囊结构无法覆盖的位置，导致无法很好地保护后座乘客的安全。
需要说明的是，在上述背景技术部分公开的信息仅用于加强对本公开的背景的理解，因此可以包括不构成对本领域普通技术人员已知的现有技术的信息。
发明内容
有鉴于此，本公开提供一种气囊袋、气囊组件和车辆，能够通过带护耳的气囊结构，更好地保护乘客的头部免受撞击。

具体实施方式
现在将参考附图更全面地描述示例实施方式。然而，示例实施方式能够以多种形式实施，且不应被理解为限于在此阐述的实施方式。相反，提供这些实施方式使得本公开将全面和完整，并将示例实施方式的构思全面地传达给本领域的技术人员。在图中相同的附图标记表示相同或类似的结构，因而将省略对它们的重复描述。
需要说明的是，在不冲突的情况下，本公开的实施例及不同实施例中的特征可以相互组合。
目前的后座安全气囊，由于充气时覆盖范围有限，仅能保护后座乘客应对正面冲击，无法照顾到后座乘客头部偏转等情况。
针对上述情况，如果将后座安全气囊的气囊主体本身扩展到覆盖更大的空间，则气囊组件的尺寸就会过大；而车辆座椅靠背空间有限，通常对气囊组件的尺寸设计有一定的限制，导致对于某些空间有限的车型来说，无法使用过大尺寸的气囊组件。
本公开提供的气囊袋，能够在对气囊组件的本身尺寸没有影响的情况下，通过对气囊主体的结构进行简单改进，在原本的气囊主体两侧增加护耳结构，实现对乘客头部的保护。
图1示出本公开实施例中气囊袋在充气状态下的立体结构，图2示出气囊袋在充气状态下的正视结构，图3示出气囊袋在充气状态下的侧视结构。其中，正视结构是以乘客视角而言，所见的气囊袋在充气状态下的结构。
此外，需要说明的是，图1至图3所示的气囊袋通过软件模拟生成，因此包含较多线条；除下文描述时指出的线条外，其余线条并不作为对本公开实施例的气囊袋的限制。
结合图1至图3所示，在一个实施例中，气囊袋包括：
气囊主体10和形成于气囊主体10的两侧的一对护耳20；
于气囊袋的充气状态下，气囊主体10展开、一对护耳20自气囊主体10的两侧背离气囊主体10伸展。
上述的气囊袋，通过在气囊主体10的两侧形成一对护耳20，实现在气囊袋的充气状态下，护耳20背离气囊主体10伸展，覆盖到气囊主体10的两侧空间；在乘客头部偏转等情况下，通过护耳20，能够保护乘客 头部免受撞击，提升安全性和可靠性。
此外，上述的气囊袋，无需对气囊主体10的结构进行过多改动，只需增加一对护耳20即可，便于实现；在气囊主体10的两侧增加护耳20的设计，也不影响气囊主体10的原本尺寸，能够适配原有的气囊组件空间，可以直接适用于与原有的气囊组件匹配的车辆中，实现在具有相当保护功能的同时兼具经济性。
图4示出本公开实施例中气囊袋的分解结构，结合图1至图4所示，在一个实施例中，护耳20包括：上片护耳布20a；下片护耳布20b，与上片护耳布20a对应缝合；护耳支撑件20c，位于气囊袋内部、衍缝于上片护耳布20a与下片护耳布20b之间；于充气状态下，护耳支撑件20c立起并支撑于上片护耳布20a与下片护耳布20b之间。
通过上片护耳布20a和下片护耳布20b，便于形成护耳20；通过护耳支撑件20c，实现在充气状态下支撑起护耳20的构型，以对乘客的头部起到缓冲保护作用。
进一步地，护耳支撑件20c具体可形成为I形片状支撑件；I形片状支撑件的两侧边分别与上片护耳布20a和下片护耳布20b衍缝、且I形片状支撑件的两端部悬空。
I形片状支撑件的两侧边可如图4所示，形成为内凹的弧形；上片护耳布20a和下片护耳布20b上，形成有对应I形片状支撑件的两侧边的衍缝纹路20c’。通过I形片状支撑件的两侧边分别与上片护耳布20a和下片护耳布20b衍缝，实现在充气状态下支撑起护耳20的构型；通过I形片状支撑件的两端部悬空，实现护耳20的内腔与气囊主体10的内腔连通，以实现气囊袋充气时护耳20随气囊主体10的同步伸展。
继续结合图1至图4所示，在一个实施例中，气囊袋包括：上片气囊布10a，上片护耳布20a一体形成于上片气囊布10a；下片气囊部10b；边侧气囊布10c，下片护耳布20b一体形成于边侧气囊布10c，上片气囊布10a、下片气囊布10b和边侧气囊布10c对应缝合；主体支撑件10d，位于气囊袋内部、衍缝于上片气囊布10a与下片气囊布10b之间；于充气状态下，主体支撑件10d立起并支撑于上片气囊布10a与下片气囊布10b之间。
通过上片气囊布10a、下片气囊部10b和边侧气囊布10c，便于形成 气囊主体10；通过主体支撑件10d，实现在充气状态下支撑起气囊主体10的构型，对乘客起到缓冲保护作用。
此外，上片护耳布20a一体形成于上片气囊布10a、下片护耳布20b一体形成于边侧气囊布10c，便于气囊袋的整体缝合，且实现相对于现有的气囊结构来说，仅需在气囊主体10的原有结构中增加耳状结构部分、同时增加耳状结构的支撑结构，即可实现本公开实施例的气囊袋，整体结构改动较小，可以适应原有的气囊组件空间，且可以直接适用于与原有的气囊组件匹配的车辆中，直接将本公开实施例的气囊袋替换至原有的气囊组件中即可，实现在具有相当保护功能的同时兼具经济性。
进一步地，主体支撑件10d具体可形成为拱形片状支撑件；于充气状态下，气囊主体10展开成拱形气囊主体，一对护耳20自拱形气囊主体的顶部两侧背离拱形气囊主体10伸展。
通过拱形片状支撑件将充气状态下的气囊主体10支撑为拱形气囊主体，能够增大撞击方向“x”的缓冲空间，进而增强气囊袋的保护作用。
主体支撑件10d与上片气囊布10a和下片气囊布10b的衍缝方式具体为：拱形片状支撑件的两侧边(如图4所示，即两个U形的边)分别与上片气囊布10a和下片气囊布10b衍缝、且拱形片状支撑件的两端部悬空。
上片气囊布10a和下片气囊布10b上，形成有对应拱形片状支撑件的两侧边的衍缝纹路10d’。通过拱形片状支撑件的两侧边分别与上片气囊布10a和下片气囊布10b衍缝，实现在充气状态下支撑起气囊主体10的构型；通过拱形片状支撑件的两端部悬空，实现气囊主体10的内腔整体贯通，从而实现气囊主体10的顺利充气。
进一步地，主体支撑件10d可包括间隔衍缝于上片气囊布10a与下片气囊布10b之间的多片，例如包括两片，但不以此为限，以增强对气囊主体10的支撑作用。
此外，气囊袋上还形成有充气孔和泄气孔。如图4所示，充气孔31可形成于上片气囊布10a，泄气孔32可形成于边侧气囊布10c。
本公开实施例还提供一种气囊组件，该气囊组件包括上述任意实施例所描述的气囊袋。上述任意实施例描述的气囊袋的特征和原理均可应用至气囊组件；因此，对已经阐明的气囊袋的特征和原理，不再重复说明。
上述的气囊组件，可用于后座气囊；在一些车型中，也可用于前座气囊、顶置气囊等等。
图5示出本公开实施例中气囊组件的使用场景，参照图5所示，由于气囊组件的气囊袋在其气囊主体10的两侧增加了护耳20，扩大了气囊袋充气时的覆盖范围，能够在碰撞发生时乘客头部40偏转的情况下，对乘客头部40起到缓冲保护作用。
本公开实施例还提供一种车辆，该车辆装配有如上述实施例描述的气囊组件。气囊组件可装配于车辆座椅靠背、或者任意合适的车内空间。
综上，本公开所提供的气囊袋、气囊组件和车辆，通过在气囊主体的两侧形成一对护耳，在气囊袋的充气状态下，护耳自气囊主体的两侧背离气囊主体伸展，覆盖到气囊主体的两侧空间，实现在乘客头部偏转等情况下，也能保护乘客头部免受撞击，提升安全性和可靠性；此外，在气囊主体两侧增加护耳的设计，无需对气囊主体的结构进行过多改动，便于实现，也不影响气囊主体的原本尺寸，能够适配原有的气囊组件空间，可以直接适用于与原有的气囊组件匹配的车辆中，实现在具有相当保护功能的同时兼具经济性。
以上内容是结合具体的优选实施方式对本公开所作的进一步详细说明，不能认定本公开的具体实施只局限于这些说明。对于本公开所属技术领域的普通技术人员来说，在不脱离本公开构思的前提下，还可以做出若干简单推演或替换，都应当视为属于本公开的保护范围。
