摘要： A mobile chair is disclosed which includes a seat form 60 having an integrally-formed back portion 61 and base portion 62. The lengths of the back and base portions can be extended by the addition of extension segments 19 and 92. An alternative seat form configuration comprises two separate portions 61 and 62 interconnected by a plurality of multileveled hinges 63, to allow the angle between the back portion 61 and the base portion 62 to be varied. The extension segments are secured to the previous extension segment or to the basic portion by two segment bolts 68 which have a threaded shaft 70 and a slotted head 69 with a threaded bore 71. The bolts engage a threaded bore 67 in the base or back portions or the threaded bore 71 of the previous extension segment bolt 68. A pommel 81 is releasably connected to the base portion 62 to improve abduction.
