Abstract

La présente demande concerne un système de fixation de sièges, notamment de chaises pour bébés ou porte-bébés, à utiliser dans des véhicules comprenant au moins deux roues. Ce système comprend une structure d'accouplement (6) qui favorise le raccordement au véhicule, et une base de pivotement (1) faisant saillie de manière à permettre le réglage angulaire du siège qui lui est accouplé, par actionnement d'au moins une poignée de blocage (4) et une poignée de réglage (5) fonctionnant de manière solidaire. On évite ainsi les déplacements intempestifs du siège par l'action d'un seul de ces éléments, favorisant ainsi la sécurité du passager.
