Abstract

La présente invention a trait à un cadre de poussette repliable comportant une paire de branches avant (1) et une paire de branches arrière (2). Les branches avant sont creuses pour recevoir les mancherons (4). Les mancherons sont globalement en forme de L et munis d'un mécanisme interne à bouton (7) pour le réglage de leur position angulaire et longitudinale. Une plate-forme de siège (21) comporte des parties extérieures (22) reliées en pivotement (23) à la branche avant (1) et reliées en articulation à des parties intérieures (24), elles-mêmes articulées l'une à l'autre. Les extrémités arrière (26) des parties extérieures sont reliées en pivotement aux glissières (27) reçues dans des rainures en porte-à-faux (28) s'étendant le long des faces intérieures des branches arrière. Un mécanisme en ciseau repliable (31) relie entre eux les côtés. Lorsque les côtés (1, 2) du siège sont repliés l'un vers l'autre, le mécanisme en ciseau se ferme et le siège est articulé vers le haut et les branches arrière pivotent vers les branches avant.
