1. A convertible wheeled patient aid for assisting a patient in a first transport mode and a second transport mode comprising: a frame having at least one wheel, a seat, a handle;a configurable back rest, configurable from a first position to a second position;a first leg rigging movably coupled to the frame from a first unstowed position to a second stowed position; and a first leg rigging retaining member, selectively engageable with the first leg rigging in the stowed position but not in the unstowed position;a second leg rigging that is separate from the first leg rigging and that is movably coupled to the frame from a first unstowed position to a second stowed position; and a second leg rigging retaining member, selectively engageable with the second leg rigging in the stowed position but not in the unstowed position;wherein the first leg rigging retaining member and the second leg rigging retaining member are physically discrete from one another such that the first leg rigging retaining member cannot selectively engage the second leg rigging and the second leg rigging retaining member cannot selectively engage the first leg rigging. 2. The patient aid of claim 1, further comprising a plurality of support members coupled to the frames for supporting a seating area of the device. 3. The patient aid of claim 1, wherein all structural members of the convertible wheeled patient aid, including a first side frame and a second side frame and a scissor frame, are aluminum or aluminum alloys. 4. The patient aid of claim 1, wherein the frame comprises a pair of side frames, wherein each of the side frames includes a longitudinal upper member and a longitudinal lower member for coupling a front member and a rear member, the longitudinal upper member being rearwardly angled for minimizing the likelihood of the person falling from the wheelchair when the person is seated in the wheelchair. 5. The patient aid of claim 1, wherein the frame comprises a pair of side frames and wherein the patient aid further comprising a pair of armrests coupled respectively to the side frames, the armrests having a front angled member for providing support to the person when the person is moving between a seating position and a standing position. 6. The patient aid of claim 1, further comprising: a rear-lower member coupled to each of a pair of side frames;a rear-upper member coupled to the rear-lower member via a latching mechanism, the rear-upper member being movable between an upright position and a lowered position; anda push-grip member coupled at an end of the rear-upper member and positioned generally perpendicular to the rear-upper member, the push-grip member being angled outward with respect to the wheelchair such that the rear-upper member is generally parallel to the rear-lower member in the lowered position. 7. The patient aid of claim 1, wherein each of a pair of side frames includes a front member and a rear member coupled via a pair of longitudinal members, the longitudinal members including an upper longitudinal member and a lower longitudinal member, the rear member being further coupled to a rear wheel such that an outer wheel periphery is below the lower longitudinal member. 8. The patient aid of claim 1, further comprising a back rest pivot point. 9. The patient aid of claim 1, further comprising a symmetrically shaped backrest. 10. The patient aid of claim 1, further comprising a cup holder. 11. The patient aid of claim 10, wherein the cup holder is coupled to the frame. 12. The patient aid of claim 10, wherein the cup holder is coupled to the upper longitudinal member. 13. A convertible wheeled patient aid for assisting a patient in a first transport mode and a second transport mode comprising: a frame having at least one wheel, a seat, a handle;a configurable back rest, configurable from a first position to a second position;a first leg rigging movably coupled to the frame from a first unstowed position to a second stowed position;a first leg rigging retaining member that pivots about a first pivot, selectively engageable with the first leg rigging in the stowed position but not in the unstowed position;a second leg rigging that is separate from the first leg rigging and that is movably coupled to the frame from a first unstowed position to a second stowed position; and a second leg rigging retaining member that pivots about a second pivot that is physically discrete from the first pivot, selectively engageable with the second leg rigging in the stowed position but not in the unstowed position.
