Abstract

La présente invention concerne un tricycle de type à siège, doté d'un siège bas et d'un cadre principal. Le cadre principal comprend un tube avant (2), un support avant (3), un support inférieur (4), un support arrière (5), et une position de fixation (8) pour siège. Des tubes doubles parallèles au milieu du support arrière (5) sont des tubes droits agencés horizontalement. Un plan formé par les axes des tubes doubles et l'axe du tube avant (2) forme un angle de 40 à 66 degrés. Le plan est situé sous le centre du cercle de section supérieure du tube avant (2), et une distance verticale entre le plan et le centre du cercle de section supérieure du tube avant (2) fait de 0 à 300 mm. Un interstice interne entre les tubes doubles parallèles au milieu des supports arrière (5) fait de 50 à 310 mm. Le siège est directement monté sur la position de fixation (8) pour siège. Le tricycle de type à siège de la présente invention ne se retourne pas facilement lorsqu'il est monté, et les performances en termes de sécurité sont meilleures.
