摘要： A chair having a base adapted to support the chair on a support surface, and a seat and backrest mounted on the base that includes a flexible backrest and a relatively simple tilt mechanism for tilting the backrest relative to the seat. The tilt mechanism includes a pair of dual cantilevered U-shaped springs mounted on opposite sides of the base and in communication with the backrest. The backrest is mounted to the tilt mechanism such that a rearward thrust applied by the user deflects an outer end of each U-shaped spring downwardly to enable rearward tilting of the backrest relative to the seat. Upon removal of the rearward thrust, the backrest elastically returns to its initial position under the biasing force of the U-shaped springs.
摘要翻译：一种椅子，其具有适于将椅子支撑在支撑表面上的底座，以及安装在基座上的座椅和靠背，该座椅和靠背包括柔性靠背和用于相对于座椅倾斜靠背的相对简单的倾斜机构。倾斜机构包括一对双悬臂U形弹簧，其安装在基座的相对侧并与靠背连通。靠背被安装到倾斜机构，使得使用者施加的向后推力使每个U形弹簧的外端向下偏转，以使得靠背相对于座椅能够向后倾斜。在去除后推力时，靠背在弹簧的偏压力作用下弹性回到初始位置。
