An adjustable chair, particularly a wheelchair, is described having a footrest (13) which can be moved rearwardly to a position between the wheels (11, 12). The seat (14) can be tilted to raise the occupant towards a standing position. The chair includes a main frame (10) and a sub-frame comprising a seat frame (39) pivotally connected to a back frame (40) carrying seat back (16). A control mechanism (17) is operable to tilt the seat (14) by raising the back frame (40) which is coupled to the frame (10) by upper and lower links (44, 45). The footrest (13) is coupled to the frame (10) by toe arms (27) and heel arms (28), the toe arms (27) being drivable by footrest drive means (22). A torso harness restrains the occupant in the standing position and knee supporting means (55) prevents buckling of the knees. Chair drive means (18) includes a drive actuator (19) which is raised with the seat (14) so a standing occupant can drive the wheelchair. |
