Abstract
The invention is directed to a seat arrangement with a seat pivotable around a horizontal pivot axis in its front region and with a variable inclination and with a backrest whose inclination can be changed compulsorily more than proportionally (super proportionally) in relationship to [or as a function of] the inclination change of the seat; herein the seat is pivotally connected to rocking levers. The rocking levers support the backrest with their respective ends. The respective ends of the rocking levers, opposite to the respective backrest supporting ends, are pivotally attached to the bearing block of the seat frame, wherein the rocking levers are articulated at the seat with spacing from the rear end of said seat and where the segments of the rocking levers rotatably supported in the bearing block and the segments of the rocking levers adjacent to the articulation axis of the seats form an obtuse angle with the base, wherein a return spring is provided for automatic return of the seat surface and backrest from the neutral into the working position if the weight is removed from the seat.

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.
