Abstract

A stroller foldable in width includes a frame and wheels under the frame. The frame comprises two side frames with rear legs, push rods connected with the upper ends of the rear legs, and backrest rods. Cross supporting rods are disposed between the two side frames. The cross supporting rods supporting the backrest rods includes a first assembly and a second assembly which are crossly configured. The first assembly includes a first upper link and a first lower link. The second assembly includes a second upper link and a second lower link. The first upper link and the second upper link are pivotally connected. The second lower link and the second upper link are pivotally connected, and a stop member is disposed between them. The first lower link and the first upper link are pivotally connected, and also a stop member is disposed between them. The cross supporting rods enable the backrest rods to be adjusted horizontally without any negative effects on folding the whole stroller.
