Description

儿童安全座椅
本申请是申请日为2018年8月28日、申请号为201810985588.9、发明名称为“儿童安全座椅”的发明专利申请的分案申请。
技术领域
本发明涉及一种儿童安全座椅。
背景技术
儿童安全座椅通常用在汽车中，以在发生意外碰撞的情况下适当地限制儿童。众所皆知，以朝后方向安装的儿童安全座椅可提供更好的保护，因为它可以将碰撞力分配到身体的较大部分(即儿童的头部和躯干)。因此安全专家和汽车座椅制造商通常建议将儿童以后向配置固定于汽车中直到2岁。
然而，目前市场上可用的儿童安全座椅的尺寸通常是为了接收身体较小的年幼儿童。这些儿童安全座椅以朝后方向安装时，没有足够的空间容纳具有长腿的大孩子。
为了弥补上述缺点，一些现有方法提供一种儿童安全座椅，其具有可伸展元件，该可伸展元件可设置在儿童安全座椅的前部，以在汽车座椅的背靠部和以朝后方向安装的儿童安全座椅的前端之间产生更大的空间。然而，可伸展元件的存在会干涉其它功能元件的操作，例如儿童安全座椅中的束带调整。
因此，目前有需要一种改良的儿童安全座椅，其可容纳不同年龄的儿童，且可至少改善以上的缺点。
发明内容
本发明提供一种儿童安全座椅，其以朝后方向安装时可调整为接收不同年龄的儿童，且具有方便操作调整的束带系统。
为实现上述目的，本发明提供一种儿童安全座椅，其包括：一支撑底座；一座椅壳体，设置于所述支撑底座上，所述座椅壳体的前端具有一开口；一束带系统，与所述座椅壳体耦接并用以限制为乘坐于所述座椅壳体上的儿童，所述束带系统包含一锁定装置和一调整带，所述锁定装置具有一夹止件，所述调整带通过所述锁定装置且通过所述开口延伸至所述座椅壳体的外侧，所述调整带的一内部在所述儿童安全座椅内介于所述锁定装置和所述开口之间延伸，所述夹止件在所述锁定装置处于放开状态时为松开所述调整带，以便所述调整带能够通过所述锁定装置移动，所述夹止件在所述锁定装置处于锁定状态时则夹持所述调整带，以阻止所述调整带通过所述锁定装置移动；以及一释锁件，可促使所述锁定装置从锁定状态切换至放开状态，其中，所述释锁件可经由一耦合组件与所述锁定装置相连接，所述耦合组件包括一缆线，所述释锁件可藉由拉动所述缆线促使所述夹止件松开所述调整带。
根据一实施例，所述缆线的一端与所述释锁件相连接，所述缆线的另一端与所述夹止件相连接。
根据一实施例，所述耦合组件还包括一致动部，所述致动部与所述夹止件相邻近，所述缆线的两端分别与所述释锁件、所述致动部相固接，所述释锁件经操作可拉动所述缆线，从而使所述致动部去接触并促使所述夹止件松开所述调整带。
根据一实施例，所述致动部与所述座椅壳体相枢接。
根据一实施例，所述释锁件设置于所述座椅壳体上。
根据一实施例，所述释锁件设置在所述座椅壳体的侧边。
根据一实施例，所述释锁件与所述座椅壳体相枢接。
根据一实施例，儿童安全座椅还包括一延伸部，所述延伸部与所述座椅壳体相连接，所述延伸部可相对所述座椅壳体移动，以从所述座椅壳体的前缘向前伸出或朝向所述座椅壳体缩回。
根据一实施例，所述束带系统包括一限制带，所述限制带与所述调整带相耦接，所述限制带可限制乘坐在所述座椅壳体上的儿童，在所述锁定装置处于放开状态下松开所述限制带将导致所述调整带朝向所述座椅壳体的内部滑动。

具体实施方式
图1绘示本发明一实施例适于在汽车座椅上提供儿童乘坐的儿童安全座椅100的立体图。儿童安全座椅100可包括一支撑底座102以及一个设置于支撑底座102上的座椅壳体104。支撑底座102可提供座椅壳体104稳固的支撑，且可让座椅壳体104调整倾斜角度。座椅壳体104可具有一座椅部106以及一背靠部108。具有座椅部106和背靠部108的座椅壳体104可为塑胶成形。根据一实施例，支撑底座102可包括一壳体110，壳体110由一硬塑材料所组成，而座椅壳体104可设置于支撑底座102的壳体110上。
座椅壳体104的座椅部106可具有一座椅表面106A供儿童乘坐，且可从背靠部108向前延伸至座椅壳体104的前端，且终止于与背靠部108相对的座椅壳体104的前缘104A。背靠部108可设有一头靠部112，其可调整以配合容纳于座椅壳体104中的儿童不同的高度。此外，座椅壳体104具有在座椅壳体104的左侧和右侧从座椅表面106A向上升起的左、右扶手114。
参阅图1，座椅壳体104可与一延伸部116相连接。更具体地说，延伸部116可与座椅壳体104相连接，以沿着从座椅壳体104的后方延伸至前方的纵轴滑动。根据一实施例，延伸部116可设置于座椅壳体104的腔部中，并位于座椅部106的座椅表面106A下方，且延伸部116的宽度从座椅部106的左侧延伸至右侧。延伸部116可相对座椅壳体104移动，以从座椅壳体104的前缘向前伸出或朝向座椅壳体104缩回。当儿童安全座椅100以朝后方向安装于汽车座椅时，延伸部116邻近于汽车座椅的背靠部，且可依需要相对于座椅壳体104移动调整。特别是，延伸部116可从座椅壳体104的前缘104A伸出，以在汽车座椅的背靠部和座椅壳体104的前面之间保留更大的空间供儿童放脚。
配合图1，图2绘示延伸部116的锁定机构的部分侧视图。参阅图1、2，延伸部116的锁定机构可包括一释锁把手117和复数个设置于座椅壳体104的锁定槽118。释锁把手117可经由一枢接件119与延伸部116相枢接，且可暴露于延伸部116的前端以便操作。此外，释锁把手117的内端具有一突出部117A，其可与任何一锁定槽118相卡合以锁定延伸部116相对于座椅壳体104的位置。释锁把手117被操作时可将突出部117A与锁定槽118脱离卡合以调整延伸部116。
继续参阅图1，束带系统120可与座椅壳体104相耦接，以限制乘坐在座椅壳体104上的儿童。束带系统120可包括复数个延伸于座椅壳体104的座椅部106与背靠部108上的限制带122、124。两条限制带122可为肩带，而限制带124可为跨带。一胸夹125可保持两条限制带122彼此相距适当的距离。限制带122可松开，以便于座椅壳体104上放置或移离儿童。儿童乘坐于座椅壳体104后，限制带122可缠绕儿童、与限制带124相固定，然后加以绷紧以牢固地限制乘坐于座椅壳体104上的儿童。
配合图1，图3绘示束带系统120的部分结构细节的局部剖视图。参阅图1、3，束带系统120还可包括一调整带126和一锁定装置128。调整带126可与限制带122相耦接，调整带126延伸于座椅部106的座椅表面106A下方并通过锁定装置128，且经由座椅壳体104的前端所设置的开口130延伸至座椅壳体104的外侧。开口130例如可设置在延伸部116上方。照顾者可方便地操作调整带126以调整限制带122。特别是，拉动调整带126以增加其伸出于开口130的长度时，可降低限制带122在背靠部108前方的长度。相反地，放松限制带122可导致调整带126通过开口130朝座椅壳体104的内部滑动。
锁定装置128隐藏在儿童安全座椅100的内部，使调整带126的内部126A在儿童安全座椅100内介于锁定装置128与开口130之间延伸。锁定装置128可固接于座椅壳体104，例如位于座椅部106的座椅表面106A下方。锁定装置128处于放开状态时允许调整带126通过锁定装置128移动，锁定装置128处于锁定状态时则阻止调整带126通过锁定装置128移动。根据一实施例，锁定装置128可包括一夹止件132和一弹簧133(以虚线显示于图3)。夹止件132可移动，以在锁定装置128处于锁定状态时夹持调整带126，并在锁定装置128处于放开状态时松开调整带126。夹止件132例如与座椅壳体104相枢接，且可相对于座椅壳体104转动以夹持和松开调整带126。弹簧133可为扭簧，且与夹止件132相连接。弹簧133可促使夹止件132夹持调整带126。
根据一实施例，锁定装置128可使得其处于锁定状态时为阻止调整带126朝松开限制带122的方向滑动，但在调整带126沿相反方向被拉动时，调整带126可促使锁定装置128切换到放开状态，以便于调整带126能够通过锁定装置128移动。举例来说，夹止件132可具有复数个齿部，其可与调整带126相卡合并产生单向的锁定作用，即阻止调整带126朝松开限制带122的方向滑动，但允许调整带126朝降低背靠部108前方的限制带122的长度的相反方向滑动。特别地，夹止部132的齿部与调整带126的接触可使得从座椅壳体104的开口130向外拉动调整带126可促使夹止件132旋转并松开调整带126，以便调整带126能够通过锁定装置128移动。
参阅图1、3，释锁件136设置于延伸部116上，且释锁件136可与锁定装置128相连接。释锁件136经操作可促使夹止件132松开调整带126，藉此将锁定装置128从锁定状态切换至放开状态。根据一实施例，释锁件136可绕为从座椅壳体104的后方延伸至前方的枢轴线与延伸部116相枢接。根据一实施例，释锁件136可设置于延伸部116的前端。释锁件136可包括杆体、旋钮或任何适合单手握住操作的结构。由于释锁件136设置于延伸部116上，释锁件136在延伸部116进行调整时可与延伸部116一起相对于座椅壳体104和锁定装置128移动。
释锁件136可经由耦合组件138与锁定装置128相连接，且耦合组件138在延伸部116进行调整时可缩短或伸展。根据一实施例，耦合组件138可包括两个杆体140、142。杆体140可与延伸部116相枢接，且杆体140的一端与释锁件136相连接，例如释锁件136可与杆体140相固接。杆体142可与座椅壳体104相枢接，且与邻近于夹止件132的致动部144相固接。此外，两个杆体140、142可滑动地互相连接，使杆体140、142可沿着从座椅部106的后方延伸至前方的轴线146相对彼此滑动。举例来说，两个杆体140、142可分别为两个可互相伸缩连接的管体。此外，两个杆体140、142的其中一个可具有一个沿着轴线146延伸且具有长形状的导引槽148(例如导引槽148可设置于杆体142中)，两个杆体140、142中的另一个可具有一可容纳于导引槽148的突出部150(例如突出部150可与杆体140相固接)，藉此两个杆体140、142可绕轴线146连动旋转。因此，当延伸部116相对于座椅壳体104进行调整时，释锁件136和杆体140可随延伸部116相对于杆体142、致动部144、座椅壳体104和锁定装置128沿着轴线146一起滑动。锁定装置128可于延伸部116进行调整时保持锁定状态。此外，释锁件136经操作可带动两个杆体140、142和致动部144绕轴线146同步转动，进而使致动部144接触并顶推夹止件136转动并松开调整带126。
藉由前述的结构，照顾者可操作释锁件136以将锁定装置128切换至放开状态，然后拉动并松开背靠部108前方的限制带122。当锁定装置128处于放开状态，松开限制带122可导致调整带126朝向座椅壳体104的内部滑动。此外，在座椅壳体104前方朝外拉动调整带126可促使夹止件136转动并松开调整带126，从而使调整带126能够通过锁定装置128滑动，以降低限制带122在背靠部108前方的长度。
图4绘示本发明另一实施例所提供的儿童安全座椅100'的立体图。如同前述，图4所示的儿童安全座椅100'可包括座椅壳体104、延伸部116以及束带系统120，其中，座椅壳体104设置于支撑底座102的壳体110上，延伸部116可移动以从座椅壳体104向前伸出，束带系统120则可用以限制为乘坐于座椅壳体106上的儿童。束带系统120可具有类似于前述的结构，包括限制带122、124、调整带126和锁定装置128(较佳地显示于图5)。此外，儿童安全座椅100'可包括一释锁件154，其可取代前述的释锁件136来促使锁定装置128从锁定状态切换至放开状态。根据图4的实施例，释锁件154设置于座椅壳体104上。
配合图4，图5绘示儿童安全座椅100'的释锁件154和束带系统120的结构细节的示意图。参阅图4、5，束带系统120的锁定装置128可隐藏在儿童安全座椅100'的内部且具有一夹止件132，其可夹持或松开调整带126，如同前实施例所述。调整带126的内部126A可在儿童安全座椅100'内介于锁定装置128和座椅壳体104的前端上的开口130之间延伸。
参阅图4、5，释锁件154可设置在座椅壳体104的侧边(例如左侧或右侧)，且释锁件154可绕一个从座椅壳体104的左侧横向地延伸至右侧的枢轴线与座椅壳体104相枢接。释锁件154可包括杆体、旋钮或任何适合单手抓握操作的结构。释锁件154可经由一耦合组件160与锁定装置128相连接，耦合组件160包括一致动部162和一被覆盖的缆线164。致动部162与夹止件132相邻近，且可与座椅壳体104相枢接。缆线164的两端分别与释锁件154、致动部162相固接。于是，释锁件154经操作可拉动缆线164，从而促使致动部162转动，使致动部162接触并促使夹止件132松开调整带126，藉此将锁定装置128从锁定状态切换至放开状态。值得一提，本发明其它实施例亦可省略致动部162并将缆线164的一端直接连接至夹止件132，使释锁件154可藉由拉动缆线164促使夹止件132转动并松开调整带126。
藉由上述结构，照顾者可操作释锁件154以将锁定装置128切换至放开状态，然后在开背靠部108前方拉动并松开限制带122。当锁定装置128处于放开状态，松开限制带122可导致调整带126朝向座椅壳体104的内部滑动。
图6绘示本发明另一实施例所提供的儿童安全座椅100”的立体图。如同前所述，图6所示的儿童安全座椅100”可包括座椅壳104、延伸部116以及束带系统120，其中，座椅壳体104设置于支撑底座102的壳体110上，延伸部116可移动以从座椅壳体104向前伸出，而束带系统120可用以限制为乘坐于座椅壳体106上的儿童。束带系统120可具有类似前述结构，包括限制带122和124、调整带126以及锁定装置128(较佳地显示于图7)，其中，调整带126与限制带122相耦接，而锁定装置128可夹持或松开调整带126。此外，儿童安全座椅100”可包括一个或复数个释锁件170，其可取代前述的释锁件136或154来将锁定装置128从锁定状态切换至放开状态。根据图6的实施例，释锁件170设置于支撑底座102上。
配合图6，图7绘示设置于儿童安全座椅100”中的束带系统120的详细结构的示意图。为了更清楚显示，图7省略显示座椅壳体104。参阅图6、7，锁定装置128可隐藏于儿童安全座椅100”的内部且包括夹止件132。更具体地说，锁定装置128可于座椅壳体104下方处与支撑底座102的壳体110相固接，且锁定装置128的夹止件132可与壳体110相枢接。调整带126可与限制带122相耦接，通过支撑底座102的壳体110内侧的锁定装置128，且经由设置于壳体110的前端的开口172向支撑底座102外延伸。于是，调整带126的内部126A可在儿童安全座椅100”内介于锁定装置128和壳体110的前端的开口172之间延伸。如同前所述，夹止件132可在锁定状态时夹持调整带126，以阻止调整带126通过锁定装置128移动，且在放开状态时松开调整带126，以便调整带126能够通过锁定装置128移动。
释锁件170可设置于支撑底座102的一侧(例如左侧或右侧)，且可绕一个从座椅壳体104的左侧横向地延伸至右侧的枢轴线与壳体110相枢接。释锁件170可包括杆体、旋钮或任何适合单手抓握操作的结构。根据一实施例，两个释锁件170可分别设置于支撑底座102的左、右两侧，以方便操作。各释锁件170可经由耦合组件176与锁定装置128相连接，耦合组件176包括一致动部178和一轴部180。根据一实施例，轴部180可延伸至支撑底座102的壳体110内部，且可与支撑底座102的壳体110相枢接，例如绕着与释锁件170相同的枢轴线枢接。各释锁件170可与轴部180的末端相固接，且致动部178可于邻近夹止件132处与轴部180相固接。于是，各释锁件170可促使轴部180和致动部178转动，进而使致动部178接触并顶推夹止件132松开调整带126，以将锁定装置128从锁定状态切换至放开状态。
值得注意的是，设置于支撑底座102上的释锁件170和锁定装置128可经由为其它结构的耦合组件互相连接。举例来说，释锁件170可经由一缆线(类似图5所示的缆线164)与致动部178相连接，而不使用如前所述的轴部180，且致动部178可在邻近于夹止件132处与壳体110相枢接。此结构可类似于图5所述的实施例，且以相同方式操作，即释锁件170可拉动缆绳并促使致动部178转动，使致动部178接触并顶推夹止件132松开调整带126。
前文描述的儿童安全座椅可在朝前方向安装时调整其前脚部空间，以容纳不同年龄的儿童。此外，儿童安全座椅包括方便调整的束带系统。
前文中已描述了用于儿童安全座椅的某些实施例。这些实施例仅为本发明的优选实施例而已，当然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所作的等同变化，仍属本发明所涵盖的范围。
