Abstract
Abstract A folding stroller for transporting children includes a pair of side rods articulated in the center having curved steering handles at the upper ends and wheels at the lower ends, a first cross rod pivotally connecting the lower ends of the side rods and articulated in the center, a pair of articulated back legs with each leg pivotally connected proximate one end to one of the side rods and provided with a wheel at the opposite end, and a second cross rod pivotally connecting the back legs and articulated in the center. The two rods and two legs together form a frame across which a seat having inflatable cushion inserts is fastened, whereupon folding of the stroller is achieved by the pivoting and articulation of the side rods, cross rods and back legs.
