Abstract

L'invention concerne un dispositif de réglage de hauteur de selle de vélo comprenant un logement qui est inséré et fixé dans le tube de support de la selle de vélo, un ressort à gaz réglable en longueur doté d'une tige de piston fixée au fond du logement et d'un tube de cylindre pouvant glisser vers le haut et vers le bas dans ledit logement, et un moyen d'actionnement de vanne qui commande une vanne du ressort à gaz. Cette vanne est disposée dans une position dans laquelle elle ne peut pas bouger contre le cadre du vélo de manière que le moyen d'actionnement de vanne puisse être maintenu sans bouger selon le mouvement ascendant et descendant de la selle de vélo et puisse fonctionner de manière stable, et un support de fixation de selle qui peut être directement et fermement disposé sur la partie supérieure du cylindre. Un cycliste est capable de régler facilement la hauteur de la selle tout en pédalant et à l'arrêt au moyen de la vanne de commande à distance avec le levier situé sur le guidon. Par conséquent, la commodité pour l'utilisateur et le durabilité du dispositif sont améliorées. En raison de la simplification de la structure dudit dispositif, ce dernier peut être facilement installé sur les vélos actuels.
