Seat in form of chair or bench - has side, back and front surfaces each having filling of varying density including middle strips of air cushion

摘要

The side surfaces are joined by the front and back surfaces and has a seat cushion with filling of varying density. Along the line of symmetry (M) running between the seat's side surfaces (24) is a middle strip (A) of high density, of roughly 80, on both sides of which are side zones (B) of lower density, of roughly 55. The middle strip consists of an air cushion with side zones of higher density on each side. The middle and side strips are the same width (b,e). The middle strip ends at the seat cushion's middle transverse axis (Q) where a transverse strip (C) of higher density extends over the whole width of the seat cushion. Filling (D) fills the area between the transverse strip (C) and upholstery back (26). ADVANTAGE - The chair is designed to relieve stress on the spine, after the used gets off the seat, it will resume its former shape.
