ABSTRACT:
A stroller base (A) detachably receives a seat structure (B) therein. The base includes forward wheel assemblies (12), rearward wheel assemblies (14) for rollably supporting the base, and wheel lock structures (60) for selectively locking the rear wheels against rotation. An upper base frame portion (20) is collapsable to a folded position (FIG. 3) and raiseable to a seat structure receiving position (FIG. 2). The upper base frame portion includes a channel guide (30) having a transverse slot (38) therein. The detachable seat structure includes a seat frame (80) with a plurality of patient supporting pads (90, 92, 94, 96) adjustably mounted thereon. Handles (84) selectively enable an attendant to lift a rearward portion of the detachable seat structure. A transverse seat frame member (88) is selectively received in the channel guide slot as the seat structure is positioned thereon and selectively lifted out of the channel guide slot as the seat is lifted therefrom. The seat frame adjustably mounts a footrest structure (140) and a roller (130) at a forward, lower end thereof. In operation, the attendant pivots the detachable seat structure about the transverse seat frame member to raise the roller above a door sill of a motor vehicle. The stroller is moved forward with the forward wheel assemblies passing below the door sill and the roller passing above the door sill. The attendant lifts the detachable seat structure by the handles raising the transverse bar from the channel guide and pivoting the chair about the roller until it is positioned over the seat of the motor vehicle. Thereafter, the base is folded and disposed in the trunk of the motor vehicle.
