Abstract A baby stroller having foldable upper, front and rear frames which carry foldable back and seat frames. A fabric cover is attached to the back and seat frames and includes a padded seat section suspended from the seat frame for supporting a child. The upper, front and rear frames are hingedly connected to one another so that they fold into side-by-side relation. The back and seat frames also fold down against the rear so that all the frames can be folded into a highly compact configuration. The seat frame is partially supported by side plates which have arcuate grooves adapted to receive and contain locking studs on the upper frame when the back and seat frames are in their erected positions. Accordingly, the upper frame is prevented from moving with respect to the front frame when the back frame is erected, and the rear frame is also prevented from moving with respect to the front frame by means of links interconnecting the two. A canopy is supported on forward and rear cross rods connected, respectively, to the seat and back frames. When the back and seat frames are folded down against the rear frame, the canopy folds down upon the back frame.
A collapsible baby stroller comprising a stroller frame; a backrest pivotally mounted on said stroller frame for swinging movement about a first axis; at least one first support element rigidly fixed to said backrest and extending upwardly therefrom; at least one second support element having a lower end hinged to a part of said stroller frame for pivotal movement about a second axis and having an upper end above said lower end; said first support element and said second support element being spaced from one another; and a canopy frame bridging the distance between said first and second support elements; said canopy frame being pivotally mounted with respect to both said first support element and said upper end of said second support element for pivotal movement about third and fourth axes respectively; said canopy frame being substantially rigid between said third and fourth axes; said first, second, third, and fourth axes being approximately parallel and being spaced from one another whereby swinging movement of said backrest about said first axis causes folding between said canopy frame and said backrest about said third axis.
