[origin: US4913493A] Semi-rigid structure which ability to the unidirectional deformation can be controlled, and particularly utilizable in the making of "ergonomic" seats, characterized in that it consists in a succession of parallel blocks 5 of rigid material joined together by narrow webs (7) of thinner and/or more flexible material, the deformation of the structure resulting from the pressing of all the webs, such a pressing being limited by ribs 8 placed inside the foresaid webs.
