First Claim
1. A seat subject to vibration comprising:
- a base including a first slide member;
a second slide member slidably mounted to the first slide member;
a seat support member pivotably mounted to the second slide member; and
means for biasing the second slide member and the seat support member to rest positions;
whereby, under vibration, the seat support member pivots relative to the base, slides relative to the base, and returns to a rest position;

Abstract
A vibration compensating vehicle seat suspension combines the vertical movement of the parallelogram suspension with the pivoting of the knee-pivot suspension. Three embodiments all include a horizontal pivot for pivoting of the seat, and a sublinkage for simultaneous vertical movement of the seat. A first embodiment includes a horizontal pivot and a vertical slide for sliding of the pivot. A rocking lever which rocks due to pivoting of the seat causes sliding of the pivot. A second preferred embodiment includes a horizontal pivot and a linkage for vertical movement of the front of the seat. A third preferred embodiment includes a horizontal pivot, a vertical slide, and a spring for biasing the pivot.
