Description

一种座椅靠背安装结构
技术领域
本发明涉及家具技术领域，具体是一座椅靠背安装结构。
背景技术
众所周知，椅子按材质分类有:实木椅,钢木椅,板式椅,玻璃椅,铁艺椅,塑料椅,布艺椅,皮艺椅, 皮革椅,发泡椅等，但是无论是什么样的椅子，其靠背是不可或缺的组成部分，在传统椅子中，很多椅子的靠背都由两种材料以上制作而成，其中以金属材料作支架，非金属材料包覆于金属材料表面作缓冲作用。包覆的方式有很多种，例如：镶嵌，螺丝固定安装，注塑等方式。其加工方法都非常复杂，安装繁琐，大量螺丝钉暴露在外影响外观等弊端。而且椅子的靠背多为整体或是部分镂空结构，根据人体工程学设计一些与人体曲线相重合的靠背，提高使用舒适感。然而受每个人的身高和体型的限制，所设计的曲线并不是都适合任何人使用，以腰部曲线为例，设计的曲线以人体脊椎走向为参考，然而大多数椅背中，人体靠在椅背上后，因为中部脊椎比较突出，所以其受到较大的压迫，即使人体靠椅背上休息时，脊椎也很难得到很好的放松，长期以往容易造成腰酸背痛的情况发生。
发明内容
为了解决上述问题，本发明提供一种具有结构简单，生产安装方便，使用方便舒适，以腰部肌肉为支撑面，不压迫脊椎的座椅靠背安装结构。
本发明的目的是这样实现的：一种座椅靠背安装结构，至少包括支撑背部的支架和将支架与椅子连接的底盘连接位，一边框覆盖于支架上，边框上端的肩托位置设有扣槽，扣槽扣置于支架的扣钩上，边框的下脚部卡于支架的边框槽内。
所述的边框由具有一定弹性的塑料材料制作。
所述的边框上还覆盖有面料层，面料层的左右两边及上边缝纫有塑胶卡条，卡条卡入沿着边框边缘延伸的卡槽内固定。
所述的面料层的下边设有硬质塑胶插片，该插片插入支架上的插槽内固定。
所述的边框下脚部略小于支架，卡入边框槽内后使用自攻牙螺丝锁紧。
所述边框的肩托位置设有软质材料制作的肩枕。
所述的软质材料可以为棉花，泡沫，海绵，PU等具有弹性的材质，在上述任一材质的外部由布料或是皮革包覆。
所述的支架上在人体腰部位置安装有腰垫。
所述的腰垫为三角形的弹性材料制作，通过螺钉安装于支架上。
本发明的有益效果是：1）结构简单，生产安装方便，使用方便舒适。2）本案改善了传统以整个人体背部做支撑时，需要压迫脊椎，使得脊椎难以放松的弊端，而改用在人体腰部位置设置弹性腰垫，其它位置镂空的方式，以人体腰部的肌肉做支撑，因此脊椎不受任何压迫得以很好的休息，且弹性腰垫能起到很好的按摩腰部肌肉的作用。3）除在肩部位置设有软质肩枕外，其它地方大多采用镂空结构，以便人体散热，炎热夏天使用更舒适。
附图说明
图1为本发明安装结构示意图；
图2为本发明面料层结构示意图；
图3为边框安装面料层结构示意图；
图4为本发明不安装面料层总装结构示意图；
具体实施方式
下面结合附图对本发明作进一步说明。
如图1，图4所示：一种座椅靠背安装结构，至少包括支撑背部的支架1和将支架1与椅子连接的底盘连接位14，一边框3覆盖于支架1上，边框3上端的肩托位置31设有扣槽32，扣槽32扣置于支架1的扣钩12上，边框3的下脚部34卡于支架1的边框槽11内。
所述的边框3由具有一定弹性的塑料材料制作。
所述的边框3下脚部34略小于支架1，卡入边框槽11内后使用自攻牙螺丝13锁紧。
所述边框3的肩托位置31设有软质材料制作的肩枕33。
所述的支架1上在人体腰部位置安装有腰垫2。
所述的腰垫2为三角形的弹性材料制作，通过螺钉安装于支架1上。
安装边框3时，先将边框3上端的肩枕位置31设有扣槽32扣置于支架1的扣钩12上固定边框的上端，由于边框3为弹性材料制作，所以在安装边框3的下脚部34时，需要将两脚稍向外扳开顺势将下脚部34卡入卡入边框槽11内，然后使用自攻牙螺丝13锁紧。与传统使用注塑等方式相比，本发明具有结构简单，安装方便，能提高生产效率、降低生产成本等优点。
设置于边框3上肩枕位置3的肩枕33能在肩部依靠椅背时起到支撑肩部放松颈部的用途。其中，肩部33为软质材料制作，所述的软质材料可以为棉花，泡沫，海绵，PU等具有弹性的材质，在上述任一材质外部由布料或是皮革包覆。能提高使用舒适度。本案改善了传统以整个人体背部做支撑时，需要压迫脊椎，使得脊椎难以放松的弊端，而改用在人体腰部位置设置弹性腰垫2，其它位置镂空的方式，以人体腰部的肌肉做支撑，因此脊椎不受任何压迫得以很好的休息，且弹性腰垫2能起到很好的按摩腰部肌肉的作用。
如图2、3所示，为了使整体更为美观，所述的边框3上还覆盖有面料层16，面料层16的左右两边及上边缝纫有塑胶卡条17，卡条17卡入沿着边框3边缘延伸的卡槽19内固定。所述的面料层16的下边设有硬质塑胶插片18，该插片18插入支架1上的插槽15内固定。通过上述结构，使得面料层16的各个边通过活动扣插的方式与边框3和支架1连接，具有结构简单、安装方便，后期清洗方便等优点。
