Claims13
A vehicle seat assembly comprising:
- a seat frame;
- a seat pan;
- and
- a plurality of vibration isolators interposed between the seat frame and the seat pan for limiting transmission of vibrations from the seat frame to the seat pan, each vibration isolator including:
- a flexible housing including at least one wall defining an interior of the housing;
- and
- an arrangement of conical disc spring members positioned in the interior and structured so that the vibration isolator provides a quasi-zero/negative stiffness response when a force applied to the isolator is within a predetermined range.
