Abstract

An actively ventilated chair includes a first distribution layer, a second distribution layer, and a fan, wherein the first distribution layer includes a large aperture on a first side and a plurality of small apertures on the second side, the second distribution layer couples to second side first distribution layer, and the fan couples to the first side of the first distribution layer such that it covers the large aperture, enabling the fan to direct air through the large aperture, into the first distribution layer, through the plurality of small apertures, and through the second distribution layer.

Claims

1. A chair component comprising:

a first distribution layer, a second distribution layer, an intermediate distribution layer located between the first distribution layer and the second distribution layer, and a fan;

wherein the first distribution layer comprises a first side fabricated from a substantially rigid material and shaped to form a large aperture, a second side fabricated from the substantially rigid material and shaped to form a plurality of small apertures, and at least two side walls adjoining opposite edges of the first side to respective opposite edges of the second side to form an enclosure;

the second distribution layer comprises the substantially rigid material and couples to an outside surface of the second side of the first distribution layer, such that the first and the second distribution layers form a substantially rigid frame enclosing the intermediate distribution layer, wherein pressure on the substantially rigid frame does not deform the intermediate distribution layer;

the intermediate distribution layer comprises a 3-dimensional mesh to enable the flow of air through the 3-dimensional mesh;

the fan couples to an outside surface of the first side of the first distribution layer and covers the large aperture, such that the fan directs air through the large aperture, into the first distribution layer, through the plurality of small apertures, through the intermediate distribution layer, and into the second distribution layer when the fan is powered on; and

an environmental sensor mechanically couples to the chair component, the environmental sensor being configured to detect a vital sign of an occupant so that the fan switches on when the vital sign exceeds a predetermined threshold.

2. The chair component of claim 1, wherein the chair component is a seat or a backrest.

3. The chair component of claim 1, wherein the first distribution layer comprises wood, steel, plastic, or aluminum.

4. The chair component of claim 1, wherein each small aperture is shaped to form a circle, oval, triangle, square, rectangle, rhombus, parallelogram, pentagon, or hexagon.

5. The chair component of claim 1, wherein the chair component is encapsulated in fabric.

6. The chair component of claim 1, wherein the intermediate distribution layer is shaped to form a plurality of channels, wherein each channel has a profile matching the shape of and aligned with a corresponding small aperture such that air directed from the fan flows freely through each of the large aperture, the first distribution layer, the corresponding small aperture, and the channel.

7. A chair-cooling system comprising;

a chair component, the chair component comprising;

a first distribution layer, a second distribution layer, an intermediate distribution layer located between the first distribution layer and the second distribution, and a fan;

wherein the first distribution layer comprises a first side fabricated from a substantially rigid material and shaped to form a large aperture, a second side fabricated from the substantially rigid material and shaped to form a plurality of small apertures, and at least two side walls adjoining opposite edges of the first side to respective opposite edges of the second side to form an enclosure;

the second distribution layer comprises the substantially rigid material and couples to an outside surface of the second side of the first distribution layer such that the first and second distribution layers form a substantially rigid frame enclosing the intermediate distribution layer, wherein pressure on the substantially rigid frame does not deform the intermediate distribution layer;

the intermediate distribution layer comprises a 3-dimensional mesh to enable the flow of air through the 3-dimensional mesh; and

the fan couples to an outside surface of the first side of the first distribution layer and covers the large aperture, such that the fan directs air through the large aperture, into the first distribution layer, through the plurality of small apertures, through the intermediate distribution layer, and into the second distribution layer when the fan is powered on;

a switch for activating the fan; and

a computer processor and a non-transitory memory with software embedded thereon, the software configured to receive a signal from an environmental sensor and control the fan in response to the signal;

wherein the environmental sensor is mechanically coupled to the chair component and configured to detect a vital sign of an occupant and the software is configured to switch on the fan when the vital sign exceeds a predetermined threshold.

8. The chair-cooling system of claim 7, wherein the environmental sensor is mechanically coupled to the chair component and configured to detect an occupant sitting in the chair and the software is configured to switch off the fan if no occupant is detected.

9. The chair-cooling system of claim 7, wherein the environmental sensor is mechanically coupled to the chair component and configured to detect a temperature and the software is configured to switch on the fan when the temperature exceeds a predetermined threshold.

10. The chair-cooling system of claim 7, wherein the environmental sensor is mechanically coupled to the chair component and configured to detect a voice command and the software is configured to switch on or switch off the fan in response to the voice command.

11. The chair-cooling system of claim 7, further comprising a transceiver configured to receive a command from a remote device and the software is configured to switch on or switch off the fan in response to the command.

12. The chair-cooling system of claim 7, wherein the remote device is a smart phone.
