SELF-PROPELLED VEHICLE DRIVER SEAT Russian patent published in 2010 - IPC B60N2/50 F16F9/18 

FIELD: automotive industry.

SUBSTANCE: proposed seat comprise base, carcass with cushion and back coupled via scissors-type guide device and vibro isolation device pivoted to carcass with the help of bracket. Vibro isolation device comprises damping element and pendulum-type suspension. Upper and lower bases of vibro isolation device make an opening for support plate to come out. One end of support plate is jointed to pendulum suspension, another one is connected with objected to be vibration-isolated. Casing upper base has opening for pendulum suspension rod to pass through. Diametre of said hole matches that of damping element inner cylindrical surface. Flexible element represents helical coil spring enveloping pendulum suspension threaded rod. Spring lower base rests upon movable circular flange of hydraulic damping element, while upper base thrusts against cover with thrust ring that enveloped aforesaid spring. Cover has a opening for pendulum suspension rod to pass through with diametre that matches that of damping element inner cylindrical surface. Damping element is formed by two coaxial cylindrical sleeves to form tight circular chamber. Upper part of said chamber is closed by sealed circular flange, while washer fitted in thrust ring and rigidly coupled with damping device upper base tightly closes lower part. Said circular chamber accommodates circular piston with throttling orifices made therein. Piston is coupled with circular flange by three tie rods. Pendulum suspension represents a threaded rod arranged coaxially inside damping element. It is coupled with support plate and with cover.

EFFECT: higher comfort.
