FIELD: transport engineering, railway transport. SUBSTANCE: invention relates to vehicle seats, namely, to suspensions of seats of locomotive drivers exposed to high vibrations in service. Proposed seat suspension contains telescopically intercoupled guides connected with base and skeleton of seat cushion, main resilient member installed between guides, shaped stop engaging through rollers with flexibly pressed rods. Suspension contains also bracket on which flexibly pressed rods are mounted and also levers, eccentrics installed for contact with flexibly pressed rods, and additional resilient member and additional rods. With levers and eccentrics being turned, flexibly pressed rods are pressed to bracket which is rigidly coupled with guide through additional rods. At no contact of eccentrics with flexibly pressed rods and additional rods, bracket is freely held in upper part of guide by additional flexible member. EFFECT: possibility of semiautomatic adjustment of seat to weight of driver. 1 dwg |
