具体实施方式
参阅图1，儿童载具1包括用于承载儿童的载具本体100及用于束缚儿童的安全带装置200。安全带装置200设于载具本体100上，安全带装置200具有用于束缚儿童的安全带22及与安全带22相连接且具有缓冲功能的缓冲组件21。缓冲组件21配置为在儿童载具1发生撞击或者突然减速时产 生缓冲移动，从而吸收撞击或突然减速的部分能量，借此能够避免安全带22对于儿童施加过度的束缚拉扯力。载具本体100可为儿童安全座椅、婴儿推车、摇篮或摇床等，其中所设有的缓冲组件21可具有相同的工作原理。以下所述的载具本体100将以儿童安全座椅为例进行说明。
参阅图1，载具本体100包括背靠部11及与背靠部11相连接的坐垫部13，且在背靠部11上设有头靠部12。头靠部12呈滑动的设置于背靠部11，以适应不同身高的儿童使用。以下将参考图1-4进一步说明安全带装置200及缓冲组件21的结构和操作细节。
参阅图1及图2，安全带装置200包括缓冲组件21及安全带22。安全带22例如为肩带。安全带22的第一端部22A与载具本体100相连接，更具体地，安全带22的第一端部22A可与背靠部11的上部或头靠部12相连接。安全带22的第二端部22B则与坐垫部13上所设置的扣具131可拆卸的连接，使安全带22在使用时得绕过儿童的身体，并在儿童载具1发生撞击或者突然减速时可对于乘坐于载具本体100中的儿童提供束缚作用。
另外，安全带22上还设有可滑动的护片23，其可提供舒适性和缓冲效果。较佳者，护片23呈柔性结构，且可增大安全带22对于儿童肩部的接触面积，有利于分散应力并提高舒适性。根据一实施例，护片23具有抱合结构，通过抱合结构的开和闭可快速方便的将护片23套设于安全带22上。例如，护片23可通过魔术贴的方式来实现抱合结构的开和闭。
参阅图1及图2，缓冲组件21分别与安全带22、载具本体100相连接。更具体地，缓冲组件21可在相对两端分别与载具本体100、安全带22相连接，且缓冲组件21与安全带22的连接处位于安全带22的第一端部22A和第二端部22B之间。根据一实施例，缓冲组件21包括一连接带211，连接带211的一端为适于连接载具本体100的第一固定端2111，连接带211的另一端为适于连接安全带22的第二固定端2112。连接带211的第一固定端2111与载具本体100相连接，其中载具本体100上例如设有供连接带211的第一固定端2111连接的锚接结构。
根据一实施例，连接带211的第一固定端2111可与载具本体100的头靠部12相连接。举例来说，所述锚接结构包括头靠部12中所固接的定位杆121，第一固定端2111可形成环形端，而借由定位杆121通过环形的第 一固定端2111可将第一固定端2111与头靠部12相固接。故，第一固定端2111可借由头靠部12、定位杆121的移动而调整高度，依据儿童的身高进行适应性的调节连接带211的高度，以满足使用需求。安装时，连接带211的第一固定端2111与设置于载具本体100的定位杆121相连接，连接带211的第二固定端2112则可介于第一端部22A和第二端部22B之间与安全带22相连接。
根据一实施例，缓冲组件21与安全带22相滑接。例如，连接带211的第二固定端2112可与安全带22上的护片23相固接。因护片23可沿安全带22滑动，连接带211的第二固定端2112与安全带22之间呈滑动的连接，使连接带211的第二固定端2112与护片23可相对于安全带22同步滑动。透过第一固定端2111和第二固定端2112的连接，连接带211可绷紧或松弛。
为了更容易理解本实施例中安全带22、连接带211及护片23的结构，图2-4所示的护片23呈半开状的抱合结构，安全带22与连接带211形成以护片23为交点的Y字形结构。该Y字形结构可在两个不同位置的连接处与载具本体100相连，其中一个连接处为连接带211的第一固定端2111与载具本体100的锚接结构相连接的连接处(即第一固定端2111与设置于头靠部12的定位杆121相接之处)，另一个连接处为安全带22的第一端部22A与背靠部11的上部或与头靠部12相连接的连接处。该两连接处的设置使得安全带22能够提供妥当的束缚力，更好地保护儿童安全。在本实施例中，连接带211的第一固定端2111、安全带22的第一端部22A分别连接至载具本体100的两连接处位于不同位置，使缓冲组件21与载具本体100的连接处和安全带22与载具本体100的连接处位于不同位置。更具体地，缓冲组件21与载具本体100的连接处可高于安全带22与载具本体100的连接处，亦即连接带211的第一固定端2111连接至载具本体100的位置高于安全带22的第一端部22A连接至载具本体100的位置。然而，连接带211的第一固定端2111和安全带22的第一端部22A分别连接至载具本体100的两连接处并不限于此，两连接处还可为同一位置或相近的位置。另外，两连接处还可一并设置在载具本体100的背靠部11或头靠部12的连接结构上。
继续参阅图1-4，缓冲组件21还包括可形变的缓冲件212，其与连接 带211相连接并可产生缓冲移动。缓冲件212可介于第一固定端2111和第二固定端2112之间与连接带211相连接。缓冲件212例如为具有弹性的片状橡胶带，但并不以此为限，还可包括弹簧结构，也可包括具有弹性的片状松紧带。缓冲件212的两端212A、212B分别与连接带211的不同位置相连接，且连接带211于缓冲件212的两端212A、212B之间形成限位段213。例如，缓冲件212的两端212A、212B可通过车缝或胶黏固接于连接带211，而限位段213可为连接带211中介于两端212A、212B之间延伸的部位。故，限位段213与缓冲件212呈重叠，且从缓冲件212的一端212A延伸至另一端212B。
根据其它实施例，缓冲件212的两端212A、212B与连接带211可呈可拆卸式的连接，例如通过扣具连接，另外，也可通过粘贴件、相配合的固定扣与固定孔、魔术贴、插接扣或按扣连接，通过可拆卸式的设置使缓冲件212的组合、更换都更为灵活、方便。
根据一实施例，载具本体100、安全带22中任一个与缓冲组件21呈可拆卸式的连接，使缓冲组件21的组合、拆卸更为灵活、方便。例如，连接带211的第一固定端2111可通过扣具、相配合的固定扣与固定孔等可拆卸式装置与载具本体100相连接，连接带211的第二固定端2112亦可通过扣具、相配合的固定扣与固定孔等可拆卸式装置与安全带22相连接。
借由所述的缓冲组件21，护片23可带动连接带211的第二固定端2112朝远离背靠部11的方向F滑动(方向F显示于图2和图3中)，使得介于护片23和缓冲件212之间的部分连接带211绷紧，且缓冲件212变形而被拉长，借此产生缓冲作用。当然，缓冲组件21可安装在安全带22的两侧或一侧。
以下参阅图1-4对儿童载具1在受到撞击或突然减速时所具有的缓冲过程进行详细说明。参阅图1及图2，儿童载具1处于正常使用状态时，缓冲组件21的缓冲件212可处于图2所示的状态，而限位段213处于褶皱态。安全带22及连接带211将儿童束缚于载具本体100，能避免儿童被抛离载具本体100，且由于连接带211的第一固定端2111和第二固定端2112分别与定位杆121和护片23相连接，使护片23紧靠儿童的身体上且连接带211处于紧绷状。
参阅图1、3，当儿童载具1发生撞击或突然减速时，儿童载具1内的儿童在惯性作用下会向前运动并带动护片23沿安全带22滑动，使得与护片23连接的缓冲组件21产生缓冲移动，尤其缓冲组件21中的缓冲件212会被拉长而变形，从而吸收撞击或突然减速的部分能量，借此避免安全带22对于儿童施加过度的束缚拉扯力，为儿童提供更佳的保护。在缓冲件212被拉长的过程中，连接带211由于不具有弹性或为较低的弹性，因此连接带211的限位段213将由于缓冲件212的变形而被展开，此时限位段213不会被完全展开，不被完全展开的限位段213并未绷紧。
参阅图4，当儿童载具1发生更强烈的撞击或更大幅度的突然减速时，缓冲组件21中的缓冲件212可发生变形而被拉伸至最长，与此同时，在缓冲件212发生变形而拉伸至最长的过程中，连接带211由于不具有弹性或为较低的弹性，因此连接带211的限位段213将由于缓冲件212拉伸至最长被完全的展开，此时连接带211亦可直接对儿童进行束缚，防止了因缓冲件212被过大的冲击力拉断而造成儿童飞出事故的发生。况且，通过限位段213也保护了缓冲件212形变恢复的功能，确保了安全带装置能多次的进行正常的使用。
配合图1，图5和图6绘示缓冲组件21的另一实施例。参阅图1、5-6，缓冲组件21如同前述分别与载具本体100、安全带22相连接。具体地，图5和图6所示的缓冲组件21包括连接带211。连接带211的第一固定端2111可与载具本体100相连接，连接带211的第二固定端2112可介于第一端部22A和第二端部22B之间与安全带22相连接。举例来说，连接带211的第一固定端2111可形成环形端并与头靠部12(显示于图1)相连接，连接带211的第二固定端2112可与安全带22上的护片23(显示于图1)相连接。此外，连接带211中介于第一固定端2111、第二固定端2112间之中间部2114与一缓冲件212’相固接。例如，中间部2114可被折叠而形成环状部，并借由缓冲件212’接合被折叠的两端以封闭环状部，从而维持中间部2114的环状部。缓冲件212’可在连接带211施加足够的施力下受破坏，使中间部2114的环状部打开，从而产生缓冲作用。根据一实施例，缓冲件212’为车缝线。然而，缓冲件212’不限于此，亦可为夹件、黏胶等。
参阅图1、5-6，当儿童载具1发生撞击或突然减速时，儿童载具1内 的儿童在惯性作用下会向前运动并带动护片23沿安全带22滑动，使得与护片23连接的缓冲组件21产生缓冲移动，尤其缓冲组件21中的连接带211会被拉伸而使缓冲件212’被拉断，从而吸收撞击或突然减速的部分能量，借此避免安全带22对于儿童施加过度的束缚拉扯力，为儿童提供更佳的保护。
本发明的儿童载具和缓冲组件的优点在于，当儿童载具发生撞击或者突然减速时，与安全带连接的缓冲组件在惯性作用下可产生缓冲移动，从而吸收撞击或突然减速的部分能量，借此能够避免安全带对于儿童施加过度的束缚拉扯力，为儿童提供更佳的保护。
以上所公开的仅为本发明的优选实施例，不能以此来限定本发明的权利范围，因此依本发明权利要求书所作的等同变化，仍属本发明所涵盖的范围。
