A wheelchair platform 1 comprises a tilting platform 2 for a wheelchair comprising a base 4 to support the wheelchair in use and a back wall 6. The platform 2 is pivotably connected between a pair of side supports 8 and the pivot axis 9 is characterized in being located forward of the back wall 6 and above the base 4 so as to ensure a reduced displacement of the center of gravity of the wheelchair and its user when the platform is tilted. Actuating means such as hydraulic rams 12, are located forward of the back wall 6, and are operable to tilt the platform 2, preferably in an arrangement whereby when the platform is fully tilted the hydraulic actuators are in their fully retracted position. The base 4 may be hinged at 18 to allow the front half 16 to be folded over for storage. The back wall has a back and/or head rest extension 7, 34, 36 that is hinged to enable it to be folded over the platform for storage and the platform may have hinged extension feet 30, 32 for stability- and castor wheels to allow mobility, which can be retractable via a compressed air mechanism. |
