The invention relates to means of transport. Forward ·nthe solution is a seat for a vehiclenespecially for the tractor it consists ofnfrom the seat itselfnand backrests that are fastened tonthe frames, from the base, from the flexiblenSien formed by a cylindrical torsion springnwrapped around the stored working shaftnin the side stands of the basena hinge formed as a parallelogram mechanism,nwhich consists of side standsnbases, moving consoles, workingnand support levers, and from the control devicenfor non-positioning of the elastic member by weightndriver. The purpose of the solution is to create such a structurensuspension seat that would allowninstalling the seat on the traffic proncenters with different working arrangementsnplaces to the driver.nThis purpose is achieved by the seat according tonof the invention, the essence of which is thatnthe ends of the control levers (15, 16)nthe seat hinges are articulatednwith movable brackets (6) and locatedninside the floor plan, ie in the massesnthe contour of the seat cushion frame (2), whereinnthe seat is equipped with a double arm lever (12)nfixed to the working shaft (1 1) with which it is mountednthe opposite ends of the working are firmly connectednthe lever (15), the spring (10) is one end thereof.nassociated with a two-arm lever (12) and a secondnthe end is connected to the base (7) viana scraping device. |
