FIELD: agricultural engineering; self-propelled vehicles.
SUBSTANCE: proposed seat contains base, skeleton with cushion and brakrest interconnected by scissor-type guide arrangement and shock-absorbing device hinge-connected with skeleton through bracket. Shock-absorbing device has swinging suspension made in form of threaded rod with spherical profile on one of its ends and threaded bushing connected with rod and also provided with spherical profile. Both spherical profiles of swinging suspension engage with conical surfaces of lower and upper plates, respectively. Resilient member is made in for of pack of series-connected resilient plate elements connected on inner diameter with outer surface of bushing which is rigidly secured by one end on base, and by other end slide fitted in guide bushing.
EFFECT: improved efficiency of vibration isolation in horizontal direction, simplified design and increased operation capabilities.
