Embodiment Construction

[0024] figure 2 A rear view of a powered electric wheelchair 20 according to one embodiment of the invention is shown. The wheelchair 20 includes a backrest 22 and a backrest adjustment assembly operatively connected to the backrest 22 . The backrest adjustment assembly may include an actuator (not shown) operatively connected to the backrest 22 via a mechanical linkage (such as an arm, rod, etc.). In this manner, the actuator can adjust the backrest 22 between an upright position and a reclined rearward position.

[0025] different from figure 1 In the wheelchair 10 shown in , the backrest adjustment assembly is positioned below and behind the backrest 22 . In addition, with wheelchair 10 ( figure 1 As compared to the backrest adjustment assembly 14 shown in ), the backrest adjustment assembly is small and compact.

[0026] image 3 A front view of powered wheelchair 20 is shown. The backrest 22 is adjustably connected to a seating area 26 . The backrest 22 includes ...
