Abstract

La présente invention porte sur un dispositif de pompage pour coussin de siège de véhicule, monté sur un coussin de siège de véhicule de façon à faire tourner un engrenage de liaison monté sur le coussin de siège de véhicule au fur et à mesure de la rotation d'un levier de commande, permettant ainsi de commander la hauteur du coussin du siège de véhicule. Le dispositif de pompage pour coussin de siège de véhicule selon la présente invention décrit ci-dessus peut générer à tout moment et dans la même position une force uniforme d'embrayage et éviter le déplacement du levier de fonctionnement afin que le levier de commande puisse être à tout moment localisé dans sa position normale. En outre, lors de l'actionnement continu du levier de fonctionnement dans la même direction, le dispositif de pompage pour coussin de siège de véhicule peut minimiser l'angle selon lequel le levier de fonctionnement fonctionne au ralenti afin d'améliorer considérablement la facilité de commande du levier de fonctionnement, permettant ainsi de transmettre efficacement la force de commande du levier de commande à l'engrenage de liaison. Il en résulte qu'il est possible d'améliorer considérablement la facilité d'emploi par un utilisateur et de favoriser finalement l'amélioration de la qualité de l'ensemble du siège. En outre, il est possible d'améliorer considérablement l'efficacité d'assemblage et la productivité.
