Seat with an air suspension

摘要

An improved seat with an air suspension is disclosed in which detector means, a control circuit and electromagnetic valves are cooperatively used to operate the air suspension so as to automatically control the amount of air to be contained within the air suspension according to the weights of different occupants of the seat. Outputs from the detection means for detecting the vertical displacements of the seat are inputted to the control circuit and held therein for a predetermined period of time before the control circuit is operated to control the amount of air to be contained within the air suspension.
