ABSTRACT:
A backrest adjusting device for a stroller includes a slidable seat slidably mounted to each of two limbs of a backrest frame member of the stroller. Each slidable seat includes a receptacle, a spring mounted in the receptacle, a first pin mounted above the spring and transversely passing through an associated limb of the backrest frame member, a stop piece mounted in the receptacle and located above the first pin thereby defining a lowermost position of the slidable seat, and a second pin projecting outward from an outer periphery thereof. A pull bar is mounted between the slidable seats. The second pins engage with sockets defined in a frame of the stroller when the backrest frame member is in a substantially upright position. The backrest frame member is pivotable to a substantially horizontal position when the second pins disengage with the sockets upon actuation of the pull bar which causes upward movement of the slidable seats.
