Variable suspension for vehicle seat - with spring loaded lever pivotted under seat and acting on variable floor mounting

Abstract

Abstract The tractor seat is supported by crossed levers, spring loaded and damped, fitted between the floor mounting (7) and the rigid plate (2) to which the seat is fitted. To alter the suspension characteristics of the suspension a spring loaded pivoted lever (51) is mounted under the seat support plate (2), with the spring (18) pulling the lever into a vertical setting. The bottom end of the lever rests against a roller (52) fitted at the end of an adjustable bar (59) whose horizontal displacement is controlled by a threaded spindle (19) and a control knob (62). The control moves a pointer (63) over a calibrated scale so that the driver can adjust the seat springing to suit his own weight.
