Abstract

本实用新型公开了一种折叠椅,其解决的技术关 键是座面的前部和后腿的端部活动连接,座面中部和 前腿中部之间用拉板活动连接。这样组成相当于四 连杆的机构,以此使座面角度随人体坐姿的变化而自 动调整,具有结构简单、使用方便、人体就坐舒适的特 点。

Description

本实用新型属日常生活用品领域,是一种改进的折叠椅。
现有折叠椅座面角度一般为固定型,也有少数折叠椅座面角度可调,有的靠座下支承弹簧弹力调节,有的采用调节装置手动调节,结构复杂,调节不便,且调节目的仅为满足人体后仰需要,当人体上身前倾时,不能随之调整,致使背椎较大弯曲,产生不适,容易疲劳。
本实用新型的目的是提供一种改进的折叠椅,其座面角度可随人体上身后仰、直坐、前倾等姿势的变换而调整。
本实用新型是这样实现的:一种折叠椅,具有靠背和座面以及支撑座面的腿,其特征是座面前部和后腿的端部活动连接,座面中部和前腿中部之间用拉板活动连接,前腿上两铰接点距离与座面上两铰接点距离之和等于拉板上两铰接点距离与后腿上两铰接点距离之和。这样由前腿、后腿、座面以及拉板之间组成两组相当于四连杆的机构,以此使座面角度随人体坐姿的变化而自动调整,而且折叠后的整个厚度不大于座面的厚度。
下面结合附图详细叙述本实用新型。
附图为本实用新型一种具体结构示意图。
结合附图,用钢管弯成“U”形,做为前腿1,并与两后腿2活动连接,后腿2上有撑,前腿1的上部设置了靠背5,在后腿2的顶部活动连接座面3前部,在座面3中部和前腿1中部之间活动连接有拉板4。
座面3的上下两面分别为软硬面,折合后从不同方向打开可分别使软面或硬面朝上供就座用。
本实用新型结构简单,使用方便,座面可随着人体坐姿的变化而自动地调整角度,使人体就座舒适,轻松愉快。
