Abstract
Abstract A foldable stroller for children is disclosed having a back formed by several longitudinal rigid and padded portions which are articulated together by means of folds. Two supporting divider portions which articulatedly connect the back supports with the frame, permit two degrees of inclination for the back. The stroller is strengthened by the employment of front and rear, articulated crossed rods. The folding control of the stroller is effected by a pair of cross pieces split into two articulated sections and a common control bar. The cross pieces are placed between the side supports of the back. When unfolded, the cross pieces support the back. The control bar, when raised, operates to fold the stroller.
