Abstract
A folding push-chair comprises two side chassis assemblies 6, each including a main support arm 8 linked to a front strut 9 and a rear strut 10. Each main support arm 8 lies parallel to the front strut 9 and cooperates therewith in a sliding manner, between an outward position when the push-chair is opened-out and a retracted position when collapsed, the rear strut 10 being coupled to the main support arm 8 and to the front strut 9 so that, during the relative sliding movement, the rear strut moves between a collapsed position in which it is closed against the main support arm and the front strut, and an opened-out position, in which it is in an active position, able to support the push-chair.
