Abstract
A vehicle seat assembly comprises a support frame attachable to a vehicle cab floor by a guide/slide rail assembly. A manually actuatable horizontally swingable lever mounted on the guide/slide rail assembly alongside the seat releasably locks the entire seat assembly is selected fore and aft positions. A seat and pivotally interconnected backrest are pivotally, slidably and resiliently mounted on the support frame. The seat is horizontally shiftable fore and aft on the support frame to vertically tilt the backrest. A manually actuatable vertically pivotable backrest adjustment bar is mounted on and extends horizontally along the front of the seat and releasably locks the seat on the support frame so as to maintain the backrest in selected tilt positions. A resilient suspension, which resiliently supports the seat and backrest on the support frame, includes a pair of helical tension springs having upper ends hooked to the upper rear of the support frame and lower ends connected to the ends of a flexible non-stretchable cable that passes beneath the seat. The cable bight is connected to stationary cable anchors and to an adjustably movable cable adjustment member, both mounted on the underside of the seat. A manually rotatable screw mounted on the front of the seat adjustably positions the cable adjustment member to adjust spring tension to account for differences in seat occupant weight and severity of road shock. Resilient bumpers reduce shock when the seat and backrest reach their vertical travel limits and dampers slow down vertical motion of the backrest.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
