An exemplary wheelchair comprises a main frame and a seat frame. Drive wheels and pivoting caster wheels are affixed to and support the main frame. The seat frame is connected to the main frame via left and right rear linkage arms, each rear linkage arm having a first end pivotally connected to the main frame and a second end pivotally connected to the seat frame, thereby allowing the seat frame to pivot relative to the main frame around a virtual pivot point. A seat plate having right, left, front, and rear sides is supported by the seat frame. A backrest frame is also connected to the seat frame. Left and right guide slots of the seat frame receive left and right guide rollers rotationally arranged at each end of a laterally oriented shaft connected to the main frame. The rear linkage arms and guide slots are configured so the virtual pivot point of the seat frame moves rearward when the seat frame is moved from an upright position to a tilted position.
