ABSTRACT:
A child's folding pushchair comprises an articulated frame made of tubular metallic elements, featuring a pair of opposed sides provided with respective locking units acting between adjacent tubular elements of the said frame, which locking units can be moved between a first operative position, in which the pushchair is locked in an opened position, and a second inoperative position in which the pushchair can be folded.
With at least one of the said locking units there cooperates a safety device adapted to maintain the said units momentarily in the said second inoperative position, so that the other locking unit can be released and thus enable the pushchair to be folded.
