Description

车辆的帘式气囊用的前方柱状装饰结构
技术领域
本发明涉及一种车辆的帘式气囊用的前方柱状装饰结构。特别是，本发明涉及不仅将车辆受到侧面冲击时展开的帘式气囊延长至驾驶座和副驾驶座的车窗、而且可以防止前方柱状装饰脱离，可以保证乘客安全的车辆的帘式气囊用的前方柱状装饰结构。
背景技术
人们从70年代开始研究气囊，在86年梅塞德斯奔驰批量生产的汽车中首次开始安装，美国国家公路交通安全管理局(NHTSA)规定所有的汽车上均有义务安装气囊，使气囊迅速地开始大众化，开始世界化。对于韩国车，开始正式安装气囊的时间是从1990年初起。
气囊是通过在汽车碰撞时冲击感应传感器使气囊内的无害的固体化学物质燃烧产生氮气来进行工作，其功能是充电气体在0.02至0.05秒内使气囊膨胀并吸收冲击，来防止司机和乘客与汽车结构物之间发生二次冲击。因此，即使在车辆完全破损的情况下也可以保证乘客的安全，或者尤其是用气囊覆盖住司机和乘客的头和胸部以求救命的可靠性非常高。
在这种车辆的交通事故中，当发生侧面的事故时危及性命的可能性非常高，从美国的交通事故统计来看，汽车侧面冲击造成的年死亡人数就达到了全部死亡人数的30％。有鉴于此，奔驰汽车最近介绍了在侧边气囊中于汽车侧部的屋顶线上安装帘式气囊的模型。
而且，这样的帘式气囊在韩国于2001年中期在所谓X的车辆中首次安装，现在积极推荐在倾覆事故频繁的SUV车辆(运动性多功能汽车)中安装。
但是，帘式气囊由于柱状装饰的结构上的缺陷，不能覆盖对应于驾驶座至副驾驶座的车窗，因而，不能完全保护乘客的生命安全，由于前方柱状装饰借助紧固件和螺栓固定，所以当帘式气囊展开时，存在前方柱状装饰脱离而对乘客造成很大伤害，或者，帘式气囊本身不能展开的问题。
发明内容
为了解决上述问题的本发明的目的，在于提供一种当车辆受到侧面冲击时，不仅可以将展开的帘式气囊延长至驾驶座和副驾驶座的车窗、而且可以防止前方柱状装饰脱离而可以保证乘客安全的车辆的帘式气囊用的前方柱状装饰结构。
本发明的上述目的是这样实现的，一种车辆的帘式气囊用的前方柱状装饰结构，其特征在于，将形成于车辆侧方底盘部上的前方柱状面板与前方柱状装饰固定，在帘式气囊内置于前方柱状装饰中的车辆的前方柱状装饰结构中，在将前方柱状装饰的一部分向下方弯曲而形成的阶梯面上装载具有下部表面敞开的中空结构的固定盖的机身，将弹簧构件的两端部连接到形成于机身下面的外周壁的固定孔中，卷取弹簧构件的线材的固定螺栓贯穿位于固定盖下方的前方柱状面板，与螺母连接。
而且，最好是在固定盖和弹簧构件的连接部中提供一种可以更有力地固定连接部的夹具，以便防止弹簧构件的脱离。
下面，通过参照本发明的优选实施例所进行的下述说明，可以使本发明的目的和其它特征和优点更加清楚。
附图说明
图1是概括表示具有本发明所述的帘式气囊用的前方柱状装饰结构的公共汽车的侧方底盘的主视图；
图2表示沿图1的II-II线剖开的帘式气囊用的前方柱状装饰结构的剖视图；
图3表示图2的帘式气囊展开状态的剖视图；
图4是表示固定盖和固定螺栓的结合关系的立体图；
图5表示图1的公共汽车的帘式气囊被展开状态的主视图。
具体实施方式
在本发明的图1至图5中涉及如下元件：前方柱状装饰12，前方柱状面板14，固定盖20，机身22，外周壁24，固定孔24a，固定螺栓32，螺母34，夹子36，弹簧构件40，帘式气囊50，底盘部60。
以下，参照附图详细说明本发明的结构。
图1是概括表示具有本发明所述的帘式气囊用的前方柱状装饰结构的公共汽车的侧方底盘主视图，图2表示沿图1的II-II线剖开的帘式气囊用的前方柱状装饰结构的剖视图，图3表示图2的帘式气囊展开状态的剖视图。
请参照图1至图3，本发明所述的车辆的帘式气囊用前方柱状装饰结构，将帘式气囊50内置于公共汽车或高级轿车侧方底盘部60中，在车辆受到侧面冲击时，通过内顶板(head lining)和前方柱状装饰(front pillar trim)向下方展开，保护乘客的生命。在此，未说明的符号100为门玻璃。
前方柱状装饰12沿前方柱状面板14的方向向下方弯曲，形成阶梯面，由与前方柱状面板14紧密接触的端部和阶梯面之间形成的空间中，内置帘式气囊50。
固定盖20的结构为，其机身22的外周面装载于前述前方柱状装饰12的阶梯面上，沿机身22的边缘部向下方延伸形成外周壁24，其整体形状为下部表面敞开的中空结构。
弹簧构件40的两端部连接到分别形成于前述固定盖20的外周壁24上的固定孔24a中。并且，通过夹子36使得弹簧构件40的两端部和外周壁24的连接部更牢固地保持。
固定螺栓32用于固定前述柱状装饰12和前方柱状面板14，该固定螺栓32贯穿形成于前方柱状装饰12的阶梯面上的下部表面和与其相对应的前方柱状面板14，通过螺母34连接起来。在此，为了让固定螺栓32最好是能够弹性支持前方柱状装饰12和前方柱状面板14，因而，弹簧构件40的线材最好是以卷绕至少一圈以上的状态连接。
参照表示帘式气囊50在车辆发生侧面冲击时被展开状态的图4，当车辆发生侧面冲击时，借助冲击感应传感器(图中未示出)展开帘式气囊50。与此同时，弹性支持在固定盖20的外周壁24和前方柱状面板14之间的弹簧构件40被拉伸，一边使前方柱状装饰12的一端部不脱离的与前方柱状装饰14隔离开，从而，使帘式气囊50向着所需的方向展开。
这时，帘式气囊50仅向所需的方向展开(箭头方向)，并且通过被拉伸的弹簧构件40的线材而不会向与展开方向相反的方向展开，因此，可以防止现有技术的结构中引起的帘式气囊的脱离。
进而，由于本发明没有采用现有的紧固件或螺栓这样的固定装置，不仅使前方柱状装饰12不会脱离，而且，前方柱状装饰12和前方柱状面板14通过弹簧构件40弹性的隔离开或者紧密接触的构成，具有帘式气囊50展开非常平滑的长处。
如图5所示，利用本发明构成的车辆帘式气囊用的前方柱状装饰结构，在车辆发生侧面冲击时，帘式气囊50不仅以可以覆盖后座的所有车窗玻璃的方式展开，而且，覆盖对应于驾驶座和副驾驶座的所有车门玻璃，在玻璃破损时，可以基本上预防司机和坐在副驾驶座上的人与车辆脱离而引起的对生命的二次威胁。
虽然以上说明的本发明局限于一个实施例，但是，本发明并不限于此，具有本发明所属的技术领域的普通技术的人员可以容易作出的变型也属于本发明的技术思想，这一点是不言自明的。
特别是，设想本发明的几个变形实施例的话，可以体现为不用线材而用条状形成弹簧构件，或者，改变前方柱状装饰的阶梯面的形状或固定螺栓或螺母等连接装置等。
具有上述结构的本发明具有，在车辆发生侧面冲击时可以防止前方柱状装饰脱离，并且可以覆盖前方车门玻璃，并且可以引导帘式气囊平滑地展开，保证乘客的安全等优点。
特别是，本发明的结构，在组装前方柱状装饰时，通过使固定螺栓和盖一体成型，可以使柱状装饰的组装工艺更加简单化。
