Abstract

L'invention concerne un appareil de réglage de position destiné à une selle de bicyclette. Cet appareil de réglage de position comprend une barre rotative et une barre à longueur réglable, ces barres étant montées sur un support de selle destiné à supporter la selle. La barre à longueur réglable comprend une extrémité supérieure fixée au support et une extrémité inférieure montée pivotante sur un emplacement arrière d'un cadre de bicyclette. La barre rotative comprend une extrémité supérieure raccordée pivotante au support de selle et une extrémité inférieure montée rotative sur un emplacement supérieur du cadre de bicyclette. Avec cette configuration, la barre rotative tourne en fonction d'une variation de longueur de la barre à longueur réglable, ce qui provoque un réglage de position de la selle. Ainsi, l'utilisateur peut régler les positions haut-bas et avant-arrière de la selle de bicyclette à l'aide d'une simple manipulation en fonction de sa morphologie et des diverses conditions d'utilisation. En outre, l'appareil de réglage de position de la présente invention permet d'atténuer les chocs auxquels la selle est soumise au moyen d'une unité absorbant les chocs située dans la barre à longueur réglable, ce qui permet d'améliorer le confort et la sécurité.
