Abstract:
An armchair with variable position comprising:a support structure resting on the ground and having a post defining a first generally vertical longitudinal axis; a first frame supported by said post comprising a first pivot defining a second generally horizontal longitudinal axis orthogonal to said first longitudinal axis; a second frame swinging at one end around said first pivot; thrust means connected to said first frame and acting against said end of said second frame to resist the swinging movement of said second frame around said second longitudinal axis; an elastic bellows secured to the frame and the seat; a seat supported by said first frame and connected to it through said bellows; a backrest supported by said second frame and connected to it through second elastic means; wherein said seat is connected to said first frame through first elastic means and through rear bearing elements, said first elastic means and said rear bearing elements allowing a rotary translatory motion around a generally spherical surface (&pgr;) said rear bearing elements being able to revolve in two opposite directions during the transversal movement of said seat, and wherein said backrest is connected to said second frame through second elastic means allowing a further rotary translatory movement of said backrest.
