1. A wheelchair frame comprising:
a main frame portion having a front end and a rear end;
a seat supported on the main frame portion so as to be oriented to support an occupant therein in a forward facing orientation;
a rear seat frame portion connected between a rear end of the seat and the main frame portion;
a rear wheel frame portion connected between the main frame portion and two rear wheels, the rear wheels supporting the main frame portion thereon proximate the rear end of the main frame portion;
a front seat frame portion connected between a front end of the seat and the main frame portion; and
a front wheel frame portion connected between the main frame portion and two front wheels, the front wheels supporting the main frame portion thereon proximate the front end of the main frame portion;
at least one of the front seat frame portion and the front wheel frame portion comprising a front seat height adjustment mechanism which is adjustable in height so as to effect dynamic adjustment of height of the front end of the seat relative to both of the front wheels simultaneously between a first position and a second position in which the height of the front end of the seat is reduced in the second position relative to the first position;
the rear seat frame portion comprising a rear seat height adjustment mechanism operatively connected between the main frame portion and the seat so as to effect adjustment of height of a rear end of the seat relative to the rear wheels upwardly from a normal driving position to a semi-standing position or a standing position; and
the front seat height adjustment mechanism and the rear seat height adjustment mechanism being linked to a single actuating member such that actuation of the single actuating member enables simultaneous lowering of the front end of the seat from the first position to the second position and raising of the rear end of the seat from the normal driving position to one of the semi-standing or the standing position.
