Abstract
Abstract A hammock for a baby carriage has a seat and a back rest. The seat includes a seat extension at the front end thereof. The seat is formed on right and left tubular slide guide rods extending longitudinally. Each of the sliders is inserted into the respective one of the slide guide rods from the front so as to be slidably guided by the slide guide rod. A belt for reinforcement is stretched between the right and left sliders. By forwardly pulling out the sliders, the seat extension is brought into a substantially horizontally extending position, whereby the hammock is provided with a seat extension function.
