Abstract: A self-deployable device for a child (1), comprising an arcuate structure (110, 120) adapted to support at least one flexible material wall (20) defining a space for receiving a child and at least four stiffener bars (201, 201?) for countering pressing down on the arcuate structure. For at least one of said bars, only one end (211, 211?) of the two ends of the bar is fastened to the arcuate structure by a fixed connection so that said bar may remain connected to the arcuate structure when said structure goes from the folded state to the deployed state and/or vice-versa.

Abstract: A folding chassis (1) for a child's pushchair comprising a plurality of up members (10, 11, 13, 13) for supporting the wheels and a support for the child, in which at least two members (10, 11, 13, 13) of said plurality of members are articulated to one another in such a way that when the chassis is in a deployed configuration the angular separation between these two members is higher than it is when the chassis is in a folded configuration, and in which each one of said two members comprises several parts (1021, 1022, 1121, 1122, 121, 122, 131, 132) able to slide relative to one another in a longitudinal direction of said member.

Abstract: A self-deployable device (1) for a child, comprising an arcuate structure (110, 120) capable of supporting in the deployed state at least one wall (20) made of flexible material defining a space for receiving a child, and at least one stiffener bar (200, 201) to withstand bearing against the arcuate structure. Just one (210, 211) of the two ends of the bar is secured to the arcuate structure by a fixed connection, such that said bar is able to remain connected to the arcuate structure when said structure passes from the folded-up state to the deployed state and/or vice versa.
