Patent

CA 2010366

A seat made of a plurality of adjacently positioned cushions is characterized by each cushions having an envelope made of a gas-tight elastic material. Each envelope has a predetermined shape under a maximum gas pressure causing no elastic extension of the material. The envelope contains a reduced internal gas pressure slightly less than the maximum gas pressure to allow the sagging of the predetermined shape. The reduced gas pressure is sufficient to prevent opposite walls of the seat to collapse one against the other upon external pressure of a portion of a human body. The material forming the envelope of the cushion has an elasticity sufficient to stretch and to conform to the contour of said portion of the human body.
