Abstract (en)
[origin: US4462604A] A main frame (11), supporting main wheels (25) at different wheel positions, is coupled to a seat erection frame (13) by a parallogram linkage. To permit matching of the erecting chair to different-size persons, for example so that it can "grow" with growth of a child for whom it is initially purchased, the parallelogram linkage (45) connecting the back (35) to the frame (13) can be provided in interchangeable sets of different-length links (45a, 45b) to respectively move the back (35) in different positions with respect to the front edge (34a) of the seat, the ground support (37) likewise being adjustable to accommodate differently tall patients, adjustment of the seat with respect to ground level being additionally obtained by adjusting the height of front caster wheels (27) with respect to the main frame. The position of the main wheels (25) can be relocated with respect to the center of the seat (33) by different pivot locations on the main frame.
