ABSTRACT:
A tiltable seat for a vehicle, such as a tractor. The seat is pivoted to a support about a pivot axis that extends in a fore and aft direction with respect to the vehicle and is located midway between the sides of the seat. A linkage connects the seat support with a fluid cylinder that is secured to the frame of the vehicle. A piston is slidable within the cylinder, and a pair of piston rods are connected to the piston and extend from opposite ends of the cylinder. One of the piston rods is pivotally connected to the seat. Connecting opposite ends of the cylinder is a conduit, and a manually adjustable valve is connected in the conduit. The weight of the operator on the seat will cause the seat to tilt when the vehicle is moving across a slope to thereby move the piston relative to the cylinder. Movement of the piston will cause fluid from one end of the cylinder to pass through the conduit to the opposite end of the cylinder and the flow of the fluid is regulated by the valve to control the tilting movement.
