Abstract

A vehicle seat for cooling and heating may include a seat pad, a mesh sheet having a certain thickness, a first film, and a porous seat cover, which are arranged sequentially in the direction in which air is introduced to flow. The seat pad has a pad hole, which allows air to pass through, and includes one or both of a seat cushion pad, which supports the buttocks of a user, and a seatback pad, which supports the upper body of the user. The mesh sheet has a porous network structure, through which air easily passes. The first film has a first film hole, which allows air to pass through. Air passages are maintained stable to maximize blowing performance, seating comfort is improved, and a ventilation structure is simplified to reduce manufacturing costs while improving productivity.

Claims

1. A vehicle seat comprising:

a seat pad having a pad hole, which allows air to pass through, wherein the seat pad includes at least a seat cushion pad, which supports buttocks of a user, and a seatback pad, which supports an upper body of the user;

a mesh sheet disposed on the seat pad and having a porous network structure, through which the air passes;

a first film disposed on the mesh sheet and having a first film hole, which allows the air to pass through; and

a porous seat cover disposed on the first film,

wherein the seat pad, the mesh sheet, the first film, and the seat cover are arranged sequentially according to a direction in which the air is introduced to flow, and

wherein the mesh sheet has a predetermined thickness.

2. The vehicle seat according to claim 1, wherein the mesh sheet is made up of flexible but incompressible material.

3. The vehicle seat according to claim 1, further comprising a second film disposed between the seat pad and the mesh sheet, wherein the second film has a second film hole therein to fluid-communicate with the first film hole through the mesh sheet and with the pad hole.

4. The vehicle seat according to claim 3, wherein number of the second film hole is smaller than the number of the first film hole.

5. The vehicle seat according to claim 3, wherein the second film, the mesh sheet, and the first film are provided inside the porous seat cover.

6. The vehicle seat according to claim 3, wherein the second film, the mesh sheet, and the first film are wrapped in sequence inside the porous seat cover.

7. A vehicle seat comprising:

a film having a film hole, which allows temperature-controlled air to pass through;

a mesh sheet disposed on the film and having a porous network structure, through which the air passes;

a seat pad disposed on the mesh sheet and having pad holes, which allow the air to pass through, wherein the seat pad includes at least a seat cushion pad, which supports buttocks of a user, and a seatback pad, which supports an upper body of the user; and

a porous seat cover disposed on the seat pad,

wherein the film, the mesh sheet, the seat pad, and the seat cover are arranged sequentially according to a direction in which the air is introduced to flow, and

wherein the mesh sheet has a predetermined thickness.

8. The vehicle seat according to claim 7, wherein the mesh sheet is made up of flexible but incompressible material.

9. The vehicle seat according to claim 7, wherein the mesh sheet includes a pair of blowing mesh portions, extending in a longitudinal direction in which the pad holes are formed to fluid-communicate therebetween, and a supply mesh portion communicating with the blowing mesh portions and the film hole to supply the air to the blowing mesh portions.

10. The vehicle seat according to claim 7, wherein the pad holes are located in surface portions of the seat cover with which body parts of the user come into contact.

11. A vehicle seat comprising:

a seat pad having a pad hole, which allows air to pass through, wherein the seat pad includes at least a seat cushion pad, which supports buttocks of a user, and a seatback pad, which supports an upper body of the user;

a mesh sheet disposed on the seat pad and having a porous network structure, through which the air passes;

a spreading film disposed on the mesh sheet and including a spread-inducing portion, which covers the pad hole, and a blow-preventing portion, which extends from the spread-inducing portion; and

a porous seat cover disposed on the mesh sheet and the spreading film,

wherein the seat pad, the mesh sheet, the spreading film, and the seat cover are arranged sequentially according to a direction in which the air is introduced to flow, and

wherein the mesh sheet has a predetermined thickness.

12. The vehicle seat according to claim 11, wherein the mesh sheet is made up of flexible but incompressible material.

13. The vehicle seat according to claim 11, wherein the area of the spreading film is smaller than the area of the mesh sheet.
