OPERATOR'S SEATS EARTHQUAKE-PROOF (OPTIONS) Russian patent published in 2018 - IPC A47C1/02 

FIELD: security facilities.

SUBSTANCE: invention relates to equipment of operator's workplace. Operator's seat is earthquake-proof, containing rails, carriage, restraint of recoil, turning device, device for fixing a turn, seat bottom, backrest, device for deflecting the backrest, lifting device, armrests, headrest and restraint system. Rails are rectilinear, and there is a plate between floor and rails. Between carriage and rails, forming the second rail bearing, vertically rotating rollers and gap adjusters are introduced from each side, each of which contains horizontally rotating roller and drive with the possibility of horizontal displacements of latter for adjusting the gap with rails. Linear movements of the carriage along rails are carried out by rolling the rollers with a step of fixing the rollback from the following series: 0.05 m, 0.1 m, 0.15 m, 0.2 m, 0.25 m. Angular movements of chair are carried out in any direction with a maximum rotation of not more than 180° with a step from the following series: 15°, 30°, 45°, 60° and 90°, and armrests are fastened to chair due to mechanical connection to the seat. On the outer surfaces of bearings a regular microrelief is formed with application of lubricant.

EFFECT: invention is aimed at improving operational reliability and increasing earthquake-proof.
