Abstract

Une poussette pour bébé pliante peut être fabriquée à un coût de fabrication réduit et présente une meilleure stabilité lorsqu'elle tient toute seule. La présente invention se rapporte à une structure autoportante destinée à une poussette pour bébé pliante comportant deux pattes arrière gauche et droite (13) qui sont dotées de roues arrière (12) aux extrémités inférieures de celles-ci et conçues de sorte que, lorsque les pattes arrière (13) sont amenées à se rapprocher l'une de l'autre dans le sens gauche-droite de la poussette pour bébé (11), la poussette pour bébé se plie et qu'une patte de support (21) qui se trouve sur les pattes arrière gauche et droite (13) vienne en contact avec le sol avec les roues arrière (12) pour permettre à la poussette pour bébé pliante de tenir toute seule. La patte de support (21) comprend deux éléments (22) de patte de support qui se croisent au niveau de la section intermédiaire de chacun des éléments de patte de support dans la direction longitudinale de ceux-ci et qui sont reliés rotatifs au niveau de la section de croisement (23). Les extrémités supérieures (22a) des éléments (22) de patte de support sont reliées, alors que les éléments (22) de patte de support sont inclinés dans le sens avant-arrière, aux pattes arrière (13) de manière à pouvoir tourner quand les pattes arrière gauche et droite (13) se rapprochent et s'éloignent l'une de l'autre. Lorsque la poussette pour bébé est pliée et qu'elle tient debout, les extrémités inférieures des deux éléments (22) de patte de support servent de sections en contact avec le sol (22b) qui sont en contact avec le sol dans des positions séparées des roues arrière (12) dans le sens avant-arrière.
