Abstract
An anti-vibration seat mount for tractors and other rough riding equipment with a paired base and top frame, the base frame separated from the top frame by a tapered spring set, with each spring interconnecting the base frame to the top frame. One tapered spring connects each distal end of the top frame to each distal end of the base frame, with the bottom of each tapered spring is mounted immovably to the base frame. A central pipe from the top frame is received into to the top of each tapered spring, downward through the center of each tapered spring. Vibration and bouncing motions of the work vehicle or tractor onto which the seat suspension is mounted are greatly reduced, with movements absorbed while self-centering back to an original position.
Claims7
A vibration dampening seat suspension, the suspension comprising:
- a paired frame with a base frame and a top frame, the base frame separated from the top frame by a tapered coil spring set, each spring of the tapered spring set having a spring top and a spring bottom, and the tapered coil spring set interconnect the top frame to the base frame;
- the base frame including a base front bar and a base rear bar, and the base front bar connected to the base rear bar with a base bar connector;
- the top frame including a top front bar and a top rear bar, and the top front bar connected to the top rear bar with a top bar connector;
- the base front bar having a first base front distal end and a second base front distal end, and the base rear bar having a first base rear distal end, and a second base rear distal end, and a spring base mounted proximate to each of the first base front distal end, the second base front distal end, the first base rear distal end, and the second base rear distal end of the base frame, and each spring bottom of each of the tapered coil springs of the tapered coil spring set received onto and immovably mounted to each spring base;
- the top front bar having a first top front distal end and a second top front distal end, and the top rear bar having a first top rear distal end and a second top rear distal end, and a spring cap mounted to each of the first top front distal end, the second top front distal end, the first top rear distal end and the second top rear distal end of the top frame, with each spring cap capping and holding in place the spring top of one spring of the tapered coil spring set;
- each spring of the tapered coil spring set having a center, with each center surrounded by one spring of the tapered coil spring set and
- a central pipe received into the center of each spring of the tapered coil spring set, one central pipe attached to each spring cap and the central pipe extending from the top frame at the spring cap and downward through the center of each of the tapered coil springs of the tapered coil spring set, and each of the tapered coil springs held in place by the central pipe mounted to each spring cap beneath the top frame.
