The chair is provided with a seat connected to a support structure of the chair by means of one or more hinged parallelograms consisting of pairs of tie-rods hinged to the seat and to the support structure. The structure of the chair backrest is integral with at least one of the tie-rods so as to allow the seat to be raised when the backrest is pushed backwards. Provision is also made for elastic means which are designed to counteract the backwards movement of the backrest. |
