Patent Images
1. A vehicle seat supporting body comprising:
- padding (6);
upholstery over at least part of said padding, defining a user supporting surface, and permeable to air at least when the user is seated;
a number of chambers which are located inside said padding, extend along parallel axes crosswise to said supporting surface, are open at opposite axial ends, and have respective volumes varying in response to oscillating movements of the user;
at least one opening defining an air inlet/outlet communicating with at least one group of said chambers located between said opening and said supporting surface; and
means for operation by compression and decompression of the air in said chambers for automatically opening and closing said opening,wherein said padding comprises at least one one-piece honeycomb body of elastically deformable material with each of said chambers being defined by a respective cell of said honeycomb body.

Abstract
A vehicle seat supporting body has padding which has a honeycomb body of elastic material and is covered with upholstery permeable to air and defining a user supporting surface; the cells of the honeycomb body extend along axes crosswise to the supporting surface, are open at the ends, and, in use, vary in volume in response to oscillating movement of the user; on the opposite side to the supporting surface, at least one opening connects the cells to the outside, and is opened/closed automatically by valves in response to compression and decompression of the air in the cells.
