用于轮椅的座位定位系统
摘要：
座位定位系统包括具有一对前槽和一对后槽的基部框架以及具有前端和后端的座位框架。座位框架被联接到基部框架并且能够相对于基部框架移动。第一对连杆可滑动地联接到所述一对前槽并且连接框架。第一对锁定装置具有适于阻止第一对连杆相对于所述一对前槽滑动的锁定构造和适于允许第一对连杆相对于所述一对前槽滑动的解锁构造。第二对连杆可滑动地联接到所述一对后槽并且连接框架。致动器枢转地连接到座位框架和基部框架两者并且被构造成延伸和收缩，以便使得座位框架相对于基部框架移动。
摘要（英）：

A seat positioning system includes a base frame having a pair of forward slots and a pair of rear slots, and a seat frame having a front end and a back end. The seat frame is coupled to the base frame and movable relative to the base frame. A first pair of linkages is slideably coupled to the pair of forward slots and connects the frames. A first pair of locking devices has a locked configuration adapted to prevent the first pair of linkages from sliding relative to the pair of forward slots and an unlocked configuration adapted to allow the first pair of linkages to slide relative to the pair of forward slots. A second pair of linkages slideably is coupled to the pair of rear slots and connects the frames. An actuator is pivotally connected to both the seat frame and the base frame and is configured to extend and contract to move the seat frame relative to the base frame.
