椅子作为居家生活、办公环境必不可少的一项生活工具，不仅居家生活使用多功能座椅有愈来愈高的舒适要求，就连办公环境也在工作效率的前提下对多功能座椅的舒适性和操作性有明显的提升要求，一般多功能座椅在传统底盘结构上的设计局限了使用者椅背后仰时，无法同时完成椅座的相应位移，由于椅背在后仰时与椅座的前后距离产生变化，在椅座位置不变的情况下，椅背与使用者背部发生相对位移和摩擦，导致不适感，目前就算个别现有产品能同时实现椅座位移的功能，但也无法达到工学性的联动效果，造成舒适性的不足和操作性的复杂。As an indispensable tool for home life and office environment, chairs not only have higher and higher comfort requirements for the use of multi-functional chairs in home life, but also in the office environment under the premise of work efficiency. Comfort and operability have obvious requirements for improvement. Generally, the design of multi-functional seats on the traditional chassis structure limits the user when the back of the chair is reclined, and the corresponding displacement of the seat cannot be completed at the same time. The distance between the front and rear of the seat changes. Under the condition that the seat position remains unchanged, the seat back and the user's back are relatively displaced and rubbed, resulting in discomfort. At present, even if some existing products can realize the function of seat displacement at the same time, they also The ergonomic linkage effect cannot be achieved, resulting in insufficient comfort and complicated operability.
    专利号为CN201520611537.1的中国发明专利公开了 “一种转椅座背同步位移***”，该专利中的结构包括椅座胶壳、椅背滑动连接架、椅背框和椅座基座，椅背滑动连接架的上端固定有椅背滑动杆，椅背滑动杆一端连接有椅背滑行球，椅背滑动连接架的下端连接椅座基座；椅背框内侧开有椅背框滑槽，椅背滑行球嵌入椅背框滑槽内，椅背框下端套有椅背转轴套筒，该椅背转轴套筒上套有椅背转轴固定器，该椅背转轴固定器固定在椅座胶壳下端；椅座胶壳下端固定有回拉弹簧，该回拉弹簧的下端连接椅座基座，该椅座基座上连接有滑行连接件，该滑行连接件也连接椅座胶壳。它能方便的实现椅背后仰时，同时完成座垫的相应位移。但是，该专利的结构只能实现椅座的水平位移，且该结构中由于滑动杆只有一端连接有椅背滑行球，可能导致椅背和坐垫的联动不稳定，体验效果差。  The Chinese invention patent with the patent number CN201520611537.1 discloses "a swivel seat back synchronous displacement system". The structure of the patent includes a seat rubber shell, a seat back sliding connection frame, a seat back frame and a seat base, and the The upper end of the back sliding connecting frame is fixed with a seat back sliding rod, one end of the seat back sliding rod is connected with the seat back sliding ball, and the lower end of the seat back sliding connecting frame is connected with the seat base; The seatback sliding ball is embedded in the chute of the seatback frame, the lower end of the seatback frame is covered with a seatback shaft sleeve, the seatback shaft sleeve is covered with a seatback shaft holder, and the seatback shaft holder is fixed on the seat rubber The lower end of the shell; the lower end of the seat rubber shell is fixed with a pullback spring, the lower end of the pullback spring is connected to the seat base, the seat base is connected with a sliding connector, and the sliding connector is also connected to the seat rubber shell. It can conveniently realize the corresponding displacement of the seat cushion when the back of the chair is reclined. However, the structure of the patent can only realize the horizontal displacement of the seat, and because only one end of the sliding rod is connected with the seat back sliding ball, the linkage between the seat back and the seat cushion may be unstable, and the experience effect is poor.
    所以需要设计一种结构更加稳定且更符合人体工程学的椅座椅背联动机构；此外，除了需要考虑结构上的联动外，还需要考虑到机构部分的安全性问题；通常做法是在用于承担椅座和靠背动作的机构部分设置外罩来有效地避免机构部分与使用者的身体、衣服发生接触；外罩既起到隔挡的作用，还能美化外观。但是由于用户在使用多功能座椅的过程中，椅座与椅背又是处于运动状态的，常规的固定外罩不能有效进行遮挡，且占用面积更大；所以还需要结合椅座、椅背的结构以及其运动轨迹设计一种更加贴合座椅的保护外罩。  Therefore, it is necessary to design a chair-seat back linkage mechanism with a more stable and ergonomic structure; in addition, in addition to the structural linkage, it is also necessary to consider the safety of the mechanism part; the usual practice is to use The mechanism part that undertakes the actions of the seat and the backrest is provided with an outer cover to effectively avoid contact between the mechanism part and the user's body and clothes; the outer cover not only acts as a barrier, but also beautifies the appearance. However, due to the fact that the seat and the seat back are in motion when the user is using the multi-functional seat, the conventional fixed cover cannot be effectively blocked, and the occupied area is larger; therefore, it is necessary to combine the seat and seat back. The structure and its trajectory design a protective cover that fits better with the seat.
