Abstract
A chair is concerned, in particular an office chair, fitted with a rocking seat (3), which is maintained in the resting position by some return springs (8) and which is preferably anchored behind the backrest (9,10 and 11) by means of one or more flexible rods or spiral springs (6) which slide across supporting components, which are preferably fixed (5), of the chair frame and which protrude above these with a section or arm, on the length of which depends the flexibility of the said spiral springs and the backrest attached. The weight of the user which rests on the seat changes the position of the said seat in opposition to the action of the said return springs (8), the upper range of the said flexible spiral springs (6) is reduced proportionally and as a result changes the position and flexibility of the backrest, ensuring the right level of comfort for people of different weight.
