ABSTRACT:
A baby carriage which can be collapsed to allow it to be carried, hooked onto an arm, and which when in open condition has a rigid back giving good support to the spine of the occupant, comprises: a pair of flat rigid members constituting the carriage back fastened to each other by a hinge on one side to allow them to adopt either a stable, roughly co-planar position or a position in which they are side by side; a first pair of arms situated at a point where the sides of the flat members opposite the sides hinged to one another are located, these being connected to the flat members to allow the latter to rotate with respect to the arms; the arms of the first pair being shaped such that their lower extremities sustain the supports for the front wheels of the carriage and their upper extremities, each with a handle, serve for steering or carrying the carriage; a second pair of arms arranged externally at the side of the arms of the first pair and articulated to them to provide with their upper furthermost parts, members with which to support the seat in the carriage, which their lower extremities sustain the carriage rear wheels; a third pair of arms articulated one to the other in their intermediate part, positioned behind the back of the carriage, roughly alongside the pair of flat members constituting the back, and connected "x" fashion to the first and second pair of arms.
