CA 2516560

The invention relates to an active suspension, for a seat (25) for the driver of a bus or heavy vehicle, comprising an electrical actuator (16), for exerting a force between the floor of the vehicle and the cushion of the seat. Height adjustment of the seat is carried out by means of the electrical actuator (16), or by means of an independent mechanical system. A controller (26) generates a force value from measurements made by sensors, arranged at various points on the suspension. The electrical actuator can be supported by passive elements (24) in parallel, whereby said elements are not permitted to be the sole suspension for the particular application.

Une suspension active pour siège (25) de conducteur d'autobus ou de véhicule lourd, qui comprend un actionneur électrique (16) permettant d'exercer une force entre le plancher du véhicule et l'assise du siège. L'ajustement de hauteur du siège est effectué par l~actionneur électrique (16) ou par un système mécanique indépendant. Un contrôleur (26) génère une consigne de force calculée à partir de mesures obtenues par des capteurs placés à divers endroits sur la suspension. L'actionneur électrique peut être soulagé par des éléments passifs (24) en parallèle ne permettant pas à eux seuls de jouer le rôle de suspension pour l'application considérée.
