TRANSPORT MEAN SEAT SUSPENSION Russian patent published in 1994 - IPC

FIELD: transport engineering. SUBSTANCE: seat suspension has sitting place 19; stationary base 1; made in special way of flat plates 8 and 9 elastic member; correcting mechanism; made of two racks 13 and 14 and screw 15 mechanism of regulation of suspension supporting capability; stabilizing device 27 and damping mechanism 28. Stabilizing mechanism is made of two parts, one of which is hinge, made of two pipes, located one in another. Ends of pipe of smaller diameter are connected with metal link, forming U-shaped structure. Free ends of link are hinged to vertical posts. Pneumatic damping mechanism 28 is made of upper and lower plates with beading, to which stretched on metal skeleton 29 hard crimping elastic surface - damping surface - damping member is hermetically fixed. Upper plate has hole 30 for air passing, over which petal-shaped no-return valve with hole. EFFECT: oscillations energy of sitting place is lower, than oscillations energy of its base. 4 dwg
