Abstract
The present invention provides simple and effective mechanisms, apparatus and self contained fluid circuitry to hydraulically actuate the vehicle's seat in generally downward movement in response to general upward movement of the vehicle's terrain contacting apparatus in relation to the vehicle's main body mass. The present invention also includes a simple device to remotely adjust and control the response movement of a hydraulic seat actuator. Also included in the invention is a means of controlling the actions of one or more hydraulic double acting piston pumps.
Claims11
A hydraulic suspension system for regulating movement of a vehicular seat in response to vertical travel of the vehicular body mass, comprising:
- (a) a hydraulic seat actuator comprising a first flexible coupling between the vehicular seat and the vehicular body mass, wherein the hydraulic seat actuator comprises a first piston reciprocally arranged within a first hydraulic cylinder and separating the first hydraulic cylinder into an upper portion and a lower portion, the first piston being adapted to move within the first cylinder in response to the relative movement of the vehicular body mass in relation to the vehicular seat;
- (b) a hydraulic response controller comprising a second piston reciprocally arranged within a second hydraulic cylinder and separating the second hydraulic cylinder into an upper portion and a lower portion, the hydraulic response controller being adapted to control and regulate the amount of fluid to and from the first hydraulic cylinder;
- and
- (c) a hydraulic response actuator comprising a second flexible coupling between the vehicular body mass and the vehicle suspension system, running gear, or terrain contacting apparatus, wherein the hydraulic response actuator comprises a third piston reciprocally arranged within a third hydraulic cylinder and separating the third hydraulic cylinder into an upper portion and a lower portion, the third piston being adapted to move within the third cylinder in response to the relative movement between the vehicular body mass and the vehicle suspension system, running gear or the terrain contacting apparatus;
- and
- (d) a source of fluid under pressure, wherein the fluid is in communication with the hydraulic seat actuator, the hydraulic response controller, the hydraulic response actuator, and a fluid reservoir.
