摘要： An exemplary wheelchair comprises a main frame and a seat frame. Drive wheels and pivoting caster wheels are affixed to and support the main frame. The seat frame is connected to the main frame via left and right rear linkage arms, each rear linkage arm having a first end pivotally connected to the main frame and a second end pivotally connected to the seat frame, thereby allowing the seat frame to pivot relative to the main frame around a virtual pivot point. A seat plate having right, left, front, and rear sides is supported by the seat frame. A backrest frame is also connected to the seat frame. Left and right guide slots of the seat frame receive left and right guide rollers rotationally arranged at each end of a laterally oriented shaft connected to the main frame. The rear linkage arms and guide slots are configured so the virtual pivot point of the seat frame moves rearward when the seat frame is moved from an upright position to a tilted position.

摘要翻译：示例性的轮椅包括主框架和座椅框架。驱动轮和枢轴脚轮被固定并支撑主框架。座椅框架通过左右后联动臂连接到主框架，每个后联动臂具有枢转地连接到主框架的第一端和枢转地连接到座椅框架的第二端，从而允许座椅框架相对枢转到虚拟枢轴点周围的主框架。具有右侧，左侧，前侧和后侧的座板由座椅框架支撑。靠背框架也连接到座椅框架。座椅框架的左右引导槽容纳旋转地布置在连接到主框架的横向定向轴的每个端部处的左右引导辊。后连杆臂和引导槽被构造成使得当座椅框架从直立位置移动到倾斜位置时，座椅框架的虚拟枢转点向后移动。
