ABSTRACT:
Adjustable damping is provided for the seat bottom cushion of a vehicle seat of the type having a seat frame which is mounted at a stationary position on the vehicle floor. A resilient seat cushion is mounted upon the seat frame and is resiliently compressed relative to the frame by the static occupant load when the occupant sits upon the seat bottom cushion. Occupant movement causes the further resilient movement of the seat bottom cushion above and below the static vertical position. A scissors mechanism acts between the vehicle body and a plate attached to or embedded in the seat bottom cushion to translate the vertical movement of the seat bottom cushion into a horizontal movement of a portion of the scissors mechanism. An adjustable damping device such as a dash pot is operatively connected to the horizontally movable portion of the scissors mechanism whereby the vertical movement of the seat bottom above and below the static vertical position is adjustably damped to provide a desired occupant ride.
