Description

气囊袋总成和帘式气囊 技术领域
本公开涉及安全气囊技术领域，具体地说，涉及气囊袋总成和帘式气囊。
背景技术
安全气囊安装时需要将折叠好的气囊袋捆束起来，装配至车辆的合适位置。为了有效捆束气囊袋，避免气囊袋松脱等问题，传统地采用胶带进行捆束。
胶带的起始位置和折叠位置的不同会对气囊袋的展开方向和性能造成影响，因此在生产过程中需要安排生产设备和人员进行操作和检测；
此外，胶带对硅胶图层气囊袋的粘连性能弱，很容易脱落，操作过程中需要格外注意，导致装配工作复杂。
由此，如何便捷有效地捆束气囊袋，既方便操作、节省装配时间，又能避免气囊袋与捆束件相对移动而造成气囊袋松脱，是目前亟待解决的问题。
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总成和帘式气囊，通过束缚卷与气囊袋相配合，便捷有效地捆束气囊袋，既方便操作、节省装配时间，又能避免气囊袋与束缚卷相对移动而造成气囊袋松脱，实现对气囊袋的稳定捆束。

在一些实施例中，所述气囊袋或所述束缚卷开设有一对U形切口，所述U形切口对应的部位形成所述卡位；所述束缚卷或所述气囊袋开设有一对U形的槽口。
在一些实施例中，所述气囊袋连接有一对挂耳，所述卡位结构或所述槽口结构位于一对所述挂耳之间。
在一些实施例中，所述束缚卷设置有撕裂部位，所述撕裂部位对应所述气囊袋的爆破展开部位。
在一些实施例中，所述束缚卷的径向尺寸小于或等于所述气囊袋的径向尺寸。
根据本公开的又一个方面，提供一种帘式气囊，所述帘式气囊配置有如上述任意实施例所述的气囊袋总成。
本公开与现有技术相比的有益效果至少包括：
本公开通过束缚卷与气囊袋相配合，利用一者设置卡位结构另一者设置槽口结构、卡位结构卡入槽口结构的设计，便捷有效地捆束气囊袋，既方便操作、节省装配时间、提高安装效率，又能避免气囊袋与束缚卷发生转动、移位等相对移动而造成气囊袋/束缚卷松脱，实现对气囊袋的稳定捆束；

图1至图3示意出本公开一种实施例中气囊袋总成的结构，其中图1示意出气囊袋总成的组装结构，图2示意出气囊袋总成的分解结构，图3示意出气囊袋的结构；图4至图6示意出本公开又一种实施例中气囊袋总成的结构，其中图4示意出气囊袋总成的组装结构，图5示意出气囊袋总成的分解结构，图6示意出气囊袋的结构。结合图1至图6所示，本公开实施例提供的气囊袋总成，包括：
折叠的气囊袋10；
束缚卷20，套装在气囊袋10上；
其中，气囊袋10设置有卡位结构11且束缚卷20设置有槽口结构22，或者，束缚卷20设置有卡位结构且气囊袋10设置有槽口结构，卡位结构11能卡入槽口结构22，使束缚卷20与气囊袋10相互限位。
图1至图6中，示意出卡位结构11设置于气囊袋10，槽口结构22设置于束缚卷20，但不以此为限；在其他实施例中，也可将卡位结构设置于束缚卷20，将槽口结构设置于气囊袋10。
本公开通过束缚卷20与气囊袋10相配合，利用一者设置卡位结构11另一者设置槽口结构22、卡位结构11卡入槽口结构22的设计，便捷有效地捆束气囊袋10，既方便操作、节省装配时间、提高安装效率，又能避免气囊袋10与束缚卷20发生转动、移位等相对移动而造成气囊袋10/束缚卷20松脱，实现对气囊袋10的稳定捆束。
本公开通过束缚卷20与气囊袋10相互限位的设计，还可使束缚卷20的易撕裂位置与气囊袋10的爆破展开部位12对应，确保气囊袋10爆破展开时有更好的响应，防止因气囊袋10与束缚卷20之间随着车辆运动发生相对移动，而影响气囊袋10的爆破展开效果。
在一些实施例中，卡位结构11包括一对卡位11’，槽口结构22包括一对槽口22’，一对卡位11’之间的距离小于一对槽口22’之间的距离。
通过一对卡位11’卡入一对槽口22’的设计，有效避免气囊袋10与束缚卷20发生相对转动；且一对卡位11’之间的距离小于一对槽口22’之间的距离的设计，有效避免气囊袋10与束缚卷20发生相对移位。如此，实现束缚卷20对气囊袋10的稳定捆束。
在一些实施例中(参照图1至图3所示)，气囊袋10或束缚卷20开设有T形缺口，T形缺口的两侧形成一对卡位11’；束缚卷20或气囊袋10开设有一对条状的槽口22’。
图1至图3中，示意出T形缺口设置于气囊袋10，条状的槽口22’设置于束缚卷20，但不以此为限；在其他实施例中，也可将T形缺口设置于束缚卷20，将条状的槽口设置于气囊袋10。
通过T形缺口，在其两侧形成一对可以翻动的卡位11’。当将束缚卷20套装在气囊袋10上并移动至条状的槽口22’来到T形缺口处，翻动卡位11’使其卡入对应的槽口22’；由于一对卡位11’卡入一对槽口22’，且一对卡位11’之间的距离小于一对槽口22’之间的距离，限制束缚卷20与气囊袋10之间沿轴向Z的移位和沿周向R的转动，如此实现束缚卷20与气囊袋10相互限位，确保束缚卷20对气囊袋10的稳定捆束。
在一些实施例中(参照图4至图6所示)，气囊袋10或束缚卷20开设有一对U形切口，U形切口对应的部位形成卡位11’；束缚卷20或气囊袋10开设有一对U形的槽口22’。
图4至图6中，示意出U形切口设置于气囊袋10，U形的槽口22’设置于束缚卷20，但不以此为限；在其他实施例中，也可将U形切口设置于束缚卷20，将U形的槽口设置于气囊袋10。
通过一对U形切口，形成一对可以翻动的卡位11’。当将束缚卷20套装在气囊袋10上并移动至U形的槽口22’来到U形切口处，翻动卡位11’使其卡入对应的槽口22’；由于一对卡位11’卡入一对槽口22’，且一对卡位11’之间的距离小于一对槽口22’之间的距离，限制束缚卷20与气囊袋10之间沿轴向Z的移位和沿周向R的转动，如此实现束缚卷20与气囊袋10相互限位，确保束缚卷20对气囊袋10的稳定捆束。
在一些实施例中，气囊袋10连接有一对挂耳16，卡位结构11或槽口结构22位于一对挂耳16之间。挂耳16用于将气囊袋挂载在车身部件上。卡位结构11位于一对挂耳16之间，使整个气囊袋10结构稳定。
在一些实施例中，束缚卷20设置有撕裂部位26，撕裂部位26对应气囊袋10的爆破展开部位12。
撕裂部位26是束缚卷20的易撕裂位置。通过束缚卷20与气囊袋10相互限位的设计，可使束缚卷20的撕裂部位26与气囊袋10的爆破展开部位12对应，确保气囊袋10爆破展开时有更好的响应，防止因气囊袋10与束缚卷20之间随着车辆运动发生相对移动，而影响气囊袋10的爆破展开效果。
在一些实施例中，束缚卷20的径向尺寸小于或等于气囊袋10的径向尺寸。如此，实现束缚卷20对气囊袋10的有效、稳定捆束。
本公开实施例还提供一种帘式气囊(CAB：CurtainAirBag)，该帘式气囊配置有如上述任意实施例所描述的气囊袋总成。
帘式气囊配置上述的气囊袋总成，能够通过束缚卷20与气囊袋10相配合，利用一者设置卡位结构11另一者设置槽口结构22、卡位结构11卡入槽口结构22的设计，便捷有效地捆束气囊袋10，既方便操作、节省装配时间、提高安装效率，又能避免气囊袋10与束缚卷20发生转动、移位等相对移动而造成气囊袋10/束缚卷20松脱，实现对气囊袋10的稳定捆束。此外，通过束缚卷20与气囊袋10相互限位的设计，还可使束缚卷20的易撕裂位置与气囊袋10的爆破展开部位12对应，确保气囊袋10爆破展开时有更好的响应，防止因气囊袋10与束缚卷20之间随着车辆运动发生相对移动，而影响气囊袋10的爆破展开效果。
本公开的气囊袋总成也可应用至其他类型的安全气囊，例如主/副驾驶座气囊、前后排侧气囊、膝部气囊等等，均可通过束缚卷20与气囊袋10的配合，实现对气囊袋10的稳定捆束，确保气囊袋10在常态下的稳定性以及在需要时的爆破展开。
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。
