Abstract
A device for ventilating chairs which has an air-permeable covering portion (13, 14) which is applied over the filling (7) of the chair, an insert (15; 59) located between the covering portion and the filling and a suction device (26) which through a system of suction openings in the covering (57, 60) and the insert (40, 56) evacuates the ventilating air. The insert (15) is joined with the covering (9) of the chair to an integrated unit, which is tightened against the filling (7), and from the insert (15) there extends a duct connection (40, 25) tightly separated from the filling, which leads the air to the suction device.
Claims17
A ventilated chair comprising:
- a cushion with a shaped filling which is capable of carrying and supporting a person sitting in the chair,
- a covering applied over the filling and over an insert located inside the covering, which insert is of an air-permeable elastic-material which is limited by a layer of airtight material,
- and a ventilating device comprising 1) a portion of said covering which is air-permeable over at least a portion thereof and which has such a surface extension that it can be touched and loaded by the body of a person sitting in the chair, and 2) a suction device that communicates with the inside of said covering portion and that, through a system of suction openings, is configured to ventilate away air that is drawn inwards through the cushion, wherein the insert has a surface extension of about the same size as said covering portion, and wherein the airtight layer of the insert is edge-wise joined with the covering to form an integrated unit, which is tightened against supporting surfaces located interiorly of the filling, and further comprising duct means, located in the filling and extending from an underside of the insert, for leading the ventilating flow of air coming out of the insert towards the suction device, wherein the insert and the duct means are sufficiently airtight to at least substantially prevent air from outside from leaking to the suction device.
A ventilated chair comprising:
- (A) a cushion including
- (1) a shaping filling,
- (2) a covering which overlies said filling, at least a portion of said covering being air-permeable,
- (3) an air-permeable insert disposed between said filling and said covering,
- (4) supporting surfaces located within said filling, and
- (5) a layer of airtight material located between said insert and said filling;
- and
- (B) a ventilating device including
- (1) a suction device, and
- (2) at least one airtight duct which is located, at least in part, in said filling and which extends from an underside of said insert to an inlet of said suction device, wherein
- a plurality of suction openings are formed within said chair to provide an airflow path leading from said portion of said covering, through said insert, and into said duct, wherein
- said insert has a surface extension which is of about the same size as said covering and which is joined edgewise, via said layer of airtight material, with said covering to form an integrated unit, and wherein
- said integrated unit is tightened against said supporting surfaces.
