Abstract:
An inclinable seat arrangement comprising a framework arranged to rest on the ground, a seat mounted on the framework by at least one articulation with a horizontal transverse axis so as to be inclinable in a range of inclined positions, and positioning means for stabilizing arranged so as to stabilize the seat in at least one of said positions when the seat supports the weight of the occupant,wherein said positioning means include manually controlled blocking means for blocking the inclination of the seat in every position within said range and elastic means for coupling the seat to the framework and defining a no-load equilibrium position when the seat is not occupied, the elastic means being arranged to exert a return couple on the seat toward the no-load equilibrium position whenever the seat occupies a position different from the equilibrium position, the return couple increasing as the seat is moved away from said equilibrium position, andwherein said elastic means comprise at least one elastic bearing forming said articulation and including rubber elements arranged to produce at least a part of said return couple, and wherein said elastic means further comprise a gas thrustor arranged to exert a force between the framework and the seat at a distance from the articulation axis, said force being substantially constant at least when the blocking means are unblocked.
