Description

儿童安全座椅
技术领域
本发明涉及一种儿童座椅，尤其是涉及一种可以利用简单结构来减少冲击力的儿童安全座椅。
背景技术
一般而言，传统的儿童安全座椅在汽车中受到外来的撞击时，对于坐在其上的儿童并没有很好的保护效果，并且传统的儿童安全座椅通常都具有很复杂的结构，因此传统的儿童安全座椅具有高成本以及低安全性的问题。
发明内容
有鉴于此，本发明的目的之一在于提供一种可以利用简单结构来减少冲击力的儿童安全座椅，以解决上述的问题。
本发明的目的是这样实现的，即揭露一种儿童安全座椅，该儿童安全座椅包含有一座椅主体以及一撞击缓冲机构。该座椅主体具有一背靠部与一座椅部，以及该撞击缓冲机构设置于该座椅部的一底面，该撞击缓冲机构包含有至少二凸出部，该些凸出部设置于该座椅部的后端并凸出于该座椅部的该底面，其中，当该儿童安全座椅设置于一汽车座椅上时，该些凸出部用以接触该汽车座椅。
综上所述，本发明所揭露的儿童安全座椅可以利用简单结构来减少冲击力，因此本发明的儿童安全座椅具有低成本以及高安全性的优势。

具体实施方式
请参阅图1以及图2，图1以及图2分别为本发明的儿童安全座椅100的一实施例的侧面示意图以及立体示意图。如图1以及图2所示，儿童安全座椅100包含有一座椅主体110、一撞击缓冲机构120。座椅主体110具有一背靠部112与一座椅部114，以及撞击缓冲机构120连接座椅部114的一底面A，撞击缓冲机构120包含有二凸出部122，位于座椅部114的一后端并且突出于座椅部114的底面A，亦即靠近座椅主体110的背靠部112，并且每一凸出部122分别位于座椅部114的后端的两侧的每一侧。惟本实施例虽以两个凸出部，并分别位于座椅部114的底面A的两侧为例做说明，但并非用以限制本发明。只要位于座椅部114的底面A并位于后端，凸出部的数量、间隔及相对位置并不受限制。
请参照图1，凸出部122用以于儿童安全座椅100设置在一汽车座椅5上时接触该汽车座椅。当冲击发生时，凸出部122让儿童安全座椅100容易陷入汽车座椅5内。如此一来，除了可以让儿童安全座椅100可以稳定置放于汽车座椅5上外，还可在座椅部114与汽车座椅5之间增加缓冲空间，并通过汽车座椅5本身的缓冲材料吸收冲击能量，以减少儿童安全座椅100内的儿童所承受的冲击能量。换言之，当一儿童坐在儿童安全座椅100上时，本发明的儿童安全座椅100可以减少儿童遭受过大的冲击力而造成伤亡。
此外，如图3所示，本发明的撞击缓冲机构120更包括一脚垫130。脚垫130设置于座椅部114的底面A的前端下，且突出于座椅部114的底面A。当儿童安全座椅100置放于一水平表面10上时，仅以凸出部122及脚垫130接触水平表面10。如图3所示，凸出部122及脚垫130之间形成一空间15。换句话说，座椅部114的底面A被抬升而仅以凸出部122及脚垫130的底面接触汽车座椅5的表面，使儿童安全座椅100与图1的汽车座椅5的接触面积减小，达到更佳的能量吸收效果。
如图1所示，较佳地，两凸出部122除了突出于座椅部114的底面A外，更凸出于座椅部114的一后侧表面B，让座椅部114更容易陷入汽车座椅5的座位部52及背靠部54。
请参照图4，其绘示本实施例的儿童安全座椅100的底面A的平面图。脚垫130以一旋转枢轴140枢接于座椅部114上，使脚垫130可以调整座椅部114的倾斜角度。较佳地，旋转枢轴140设置于该座椅部114的底面上的一凹槽150内，并靠近凹槽150的槽底设置。如此一来，脚垫130与座椅部114的接触面积得以减小。因此，本实施例的脚垫130除了可以调整座椅部的倾斜角度，使乘坐在内的婴儿觉得舒适外，还可以减小座椅部114的底面A与汽车座椅5的接触面积。
另外也较佳地，旋转枢轴140实质上设置于座椅部114的前后方向上的中央处，同样可使脚垫130往下转动调整后与座椅部114的接触面积减小。
凸出部122与汽车座椅5接触的底面形状可以设计为各种形状，例如矩形、椭圆形、圆形及方形等。请参照图2或图4，根据本实施例进行测试，当凸出部的宽度W介于0.1英寸至1英寸之间，较佳地介于0.125英寸至0.75英寸之间时有较佳的吸收冲击效果。
更具体地来说，由于凸出部122的截面积远小于座椅部114的底面A的截面积，所以在本发明的一撞击测试中可以发现本发明的儿童安全座椅100所具有的保护功能会因儿童安全座椅100的撞击缓冲机构120的二凸出部122陷入进入汽车座椅5而产生，因此坐在儿童安全座椅100上的儿童受到的撞击力道会得到有效地降低。此外，请参照图2或图4，在本发明的该撞击测试中可以发现每一凸出部122用以接触该汽车座椅的底面的宽度W在介于0.125英寸与0.75英寸之间时的情况下可以减少较多的冲击力。
请参照下表一，其比较有凸块及没有凸块的情况下测试得到的胸腔加速度统计值。从表一中可以看出，同样使用12个月大的假人(dummy)(22磅)，有凸出部的汽车椅测得的胸腔加速度平均值为48.1(Gs)，而标准差为2.76(Gs)；相对的，没有凸出部的汽车椅测得的胸腔加速度平均值为64.2，而标准差为10.41。由此可以看出，使用有凸出部的汽车椅所测得的胸腔加速度值显著较低，同时测得的数据表现也比较稳定。在使用6岁大假人(51.6磅)的测试数据中也可以观察到同样的结果。由此可以证明，具有凸出部的汽车椅具有较佳并稳定的吸收冲击能量的效果。
表一
Figure G2008101782797D00041
另外，撞击缓冲机构120与其凸出部122可以经由塑胶射出成形一体形成在座椅部114的底面A；也可以将凸出部122做成独立的零组件，在座椅部114的底面A形成安装部(未绘示)，再将凸出部122通过安装部结合于座椅部114的底面A上，其中，凸出部122的形状以及尺寸可以改变。在本发明的该撞击测试中，如图1以及图2所示的凸出部122的形状及尺寸可以减少较多的冲击力。在此请注意，上述的实施例仅作为本发明的举例说明，而不是本发明的限制条件。
综上所述，本发明所揭露的儿童安全座椅可以利用简单结构来减少冲击力，因此本发明的儿童安全座椅具有低成本以及高安全性的优势。
以上所述仅为本发明的较佳实施例，凡依本发明权利要求所做的均等变化与修饰，皆应属本发明的涵盖范围。
