Abstract
A backrest structure for strollers has a linkage bar to connect the frame and the backrest to enable the backrest of the stroller to be folded or anchored synchronously with the collapsing or extending of the frame. The backrest structure includes a backrest-adjusting device to provide the linkage movement and also offer multiple stage adjustment of the backrest angle.
