Baby carriage and method of manufacturing seat plate for its seat

摘要

A flat seat plate (8) providing an upper surface (7) which is in contact with a principal region of the lower surface of a seat portion for supporting the seat portion from below is integrated into a part of the body of a baby carriage (1). The seat plate (8) is divided into three plate-type members (22 to 24), and adjacent ones of the plate-type members (22 to 24) are hinged with each other on the respective lower surface sides thereof by flexible sheets. End surfaces of the plate-type members (22 to 24) are butted against each other when the seat plate (8) defines a uniform plane.
