LOCOMOTIVE DRIVER SEAT Russian patent published in 2005 - IPC

FIELD: railway transport.

SUBSTANCE: invention relates to devices designed for protecting men from harmful action of vibration and it can be used in vibration protection system of vehicles exposed to vibration. Proposed locomotive driver seat contains tubular framework of seat, backrest with porolon cushions, armrests, support disk, rod, inner cylinder of seat suspension, outer cylinder of seat suspension, lock, spring resting of suspension base, rolls-vibration isolators with axles and brackets for fastening. Moreover, seat contains aerodynamic vibration generator with shaped wall of regulate amplitude frequency characteristics of vibration parameters to tolerable sanitary-hygienic requirements. Rod is connected with support disk with gasket-diaphragm made of elastic material and it passes through guide bushing with cup connected by square thread with inner cylinder of seat suspension. Outer cylinder of suspension is connected with guide bushing by lock. Several rolls-vibration isolators made of elastic material and insulating from vertical vibrations, secured on axles of brackets and connected with inner cylinder of suspension, roll over lower or upper webs of H-section circle secure on outer cylinder of seat suspension, and several rolls-vibration isolators made of elastic material and insulating from horizontal vibrations are secured on vertical axles connected with outer surface of wall of inner cylinder of seat suspension from other side.

EFFECT: provision of active protection of men from harmful vibrations with possibility of control of amplitude-frequency characteristics of vibration parameters to bring them to tolerable sanitary and hygienic requirements.
