Abstract

A seat component for a vehicle seat having at least one air outlet unit configured to be connected to an air supply. In order to be able to adapt a ventilation function of the vehicle seat individually to a contact area between the vehicle seat and a person sitting thereon, the air outlet unit has at least one flexible air guide funnel and at least one diaphragm valve which is arranged within the at least one flexible air guide funnel and which is connected to the at least one flexible air guide funnel in such a way that the diaphragm valve closes the air guide funnel when the air guide funnel is not deformed, and at least partially opens the air guide funnel when the air guide funnel is deformed.

First claim

What is claimed is:

1. A seat component for a vehicle seat, the seat component comprising:
at least one air outlet unit configured to be connected to an air supply, the at least one air outlet unit having at least one flexible air guide funnel and at least one diaphragm valve arranged within the at least one flexible air guide funnel and connected to the at least one flexible air guide funnel such that the at least one diaphragm valve closes the at least one flexible air guide funnel when the at least one flexible air guide funnel is not deformed, and at least partially opens the at least one flexible air guide funnel when the at least one flexible air guide funnel is deformed, wherein the at least one flexible air guide funnel has an axial top end forming an air inlet opening and an axial bottom end forming an air outlet opening, and wherein the at least one flexible air guide funnel has, in a connection region to the at least one diaphragm valve, at least one material weakening formed of solid material with a groove which is arranged on the at least one flexible air guide funnel in an at least partially encircling manner.

2. The seat component according to claim 1 , further comprising at least one air supply duct connected to the at least one air outlet unit in a communicating manner.

3. The seat component according to claim 1 , further comprising at least one air supply cushion connected to the at least one air outlet unit in a communicating manner.

4. The seat component according to claim 1 , wherein the at least one air outlet unit is a monolithically produced injection-molded component.

5. The seat component according to claim 1 , wherein at least two air outlets are arranged on the at least one flexible air guide funnel, of which at least one air outlet is arranged on a shell of the at least one flexible air guide funnel.

6. The seat component according to claim 1 , further comprising at least one mat which is composed of a flexible foam and on which at least one aperture is formed, within which the at least one air outlet unit is at least partially arranged.

7. The seat component according to claim 1 , further comprising at least one resistance heating element.

8. The seat component according to claim 1 , further comprising at least one air-permeable substance which covers the at least one air outlet unit on a seat surface side.

9. A seat component for a vehicle seat, the seat component comprising:
an air outlet unit configured to be connected to an air supply, the air outlet unit having a flexible air guide funnel and a diaphragm valve is arranged within the flexible air guide funnel and connected to the flexible air guide funnel such that the diaphragm valve closes the air guide funnel when the flexible air guide funnel is not deformed, and at least partially opens the flexible air guide funnel when the flexible air guide funnel is deformed, wherein the at least one flexible air guide funnel has an axial top end forming an air inlet opening and an axial bottom end forming an air outlet opening, and wherein the at least one flexible air guide funnel has, in a connection region to the at least one diaphragm valve, at least one material weakening formed of solid material with a groove which is arranged on the at least one flexible air guide funnel in an at least partially encircling manner.

10. A vehicle seat comprising:
a seat component which forms at least one portion of a backrest or of a seat base of the vehicle seat, the seat component comprising:
at least one air outlet unit configured to be connected to an air supply, the at least one air outlet unit having at least one flexible air guide funnel and at least one diaphragm valve arranged within the at least one flexible air guide funnel and connected to the at least one flexible air guide funnel such that the at least one diaphragm valve closes the at least one flexible air guide funnel when the at least one flexible air guide funnel is not deformed, and at least partially opens the at least one flexible air guide funnel when the at least one flexible air guide funnel is deformed, wherein the at least one flexible air guide funnel has an axial top end forming an air inlet opening and an axial bottom end forming an air outlet opening, and wherein the at least one flexible air guide funnel has, in a connection region to the at least one diaphragm valve, at least one material weakening formed of solid material with a groove which is arranged on the at least one flexible air guide funnel in an at least partially encircling manner.

11. The vehicle seat according to claim 10 , further comprising at least one air supply duct connected to the at least one air outlet unit in a communicating manner.

12. The vehicle seat according to claim 10 , further comprising at least one air supply cushion connected to the at least one air outlet unit in a communicating manner.

13. The vehicle seat according to claim 10 , wherein the at least one air outlet unit is a monolithically produced injection-molded component.

14. The vehicle seat according to claim 10 , wherein at least two air outlets are arranged on the at least one flexible air guide funnel, of which at least one air outlet is arranged on a shell of the at least one flexible air guide funnel.

15. The vehicle seat according to claim 10 , further comprising at least one mat which is composed of a flexible foam and on which at least one aperture is formed, within which the at least one air outlet unit is at least partially arranged.

16. The vehicle seat according to claim 10 , further comprising at least one resistance heating element.

17. The vehicle seat according to claim 10 , further comprising at least one air-permeable substance which covers the at least one air outlet unit on a seat surface side.
