Claims

[Scope of utility model registration request]

(1) An inner shaft with a polygonal cross section is passed through an outer cylinder with a polygonal cross section, and an elastic member is inserted into the gap formed between the inner surface of a corner of the outer cylinder and the circumferential surface of the inner shaft facing thereto. In a seat suspension structure in which a link mechanism for supporting a seat is coupled to the inner shaft of a filled Neidhardt spring, a means is provided for adjusting the relative rotational position of the outward and inner shafts independent of the load from the seat. The seat suspension structure is characterized by the following features:

(2) The seat suspension structure according to claim 1, wherein the adjustment means is connected to an outer cylinder. Cylinder: The inner shaft passing through the outer cylinder is divided into two parts, one shaft is connected to a link mechanism, and the other shaft is connected to the adjustment means. Seat suspension structure as described in section.
