Abstract
Abstract A baby carriage comprises a frame structure and a compartment for accommodating an infant, the compartment being formed by substantially air-tight materials and including a back rest having formed therein an opening. A perforated member extends substantially coextensively with and over the opening. There is provided a cover coextensive with the opening and capable of covering and uncovering the opening. One of a pair of slide fastener stringers is secured to and along the marginal edges of the cover, and the other stringer to and along, the marginal edges of the opening. The stringers are coupled or uncoupled by a slider to attach the cover over the opening or detach the cover from the opening.
