A seat pad 10 comprises a cushion pad 11 as a seat portion to be sat on, wherein a high ventilation member 12 higher in ventilation property than a cushion pad member forming the cushion pad 11 is embedded in a part of the cushion pad 11 except a under-hip portion located under hips when sitting, in a state of being exposed only to a rear side of the cushion pad.
First claim
Opening claim text (preview).
The invention claimed is: 1. A seat pad comprising a cushion pad configured to be a seat portion to be sat on, wherein a high ventilation member higher in ventilation property than a cushion pad member forming the cushion pad is embedded in a part of the cushion pad except a under-hip portion configured to be located under hips when sitting, in a state of being exposed only to a rear side of the cushion pad, and the high ventilation member extends across an entire width of a flat surface portion of the front surface of the seat pad and is not divided in a width direction of the seat pad. 2. The seat pad according to claim 1 , wherein the high ventilation member is embedded only in a under-thigh portion of the cushion pad configured to be located under thighs when sitting. 3. The seat pad according to claim 1 , wherein a thickness of the high ventilation member is 20% or more of a total thickness of the cushion pad and the high ventilation member at a position where the high ventilation member is embedded. 4. The seat pad according to claim 1 , wherein the high ventilation member is inserted in the cushion pad in a state of being compressed in a planar view lateral direction of the high ventilation member. 5. The seat pad according to claim 1 , wherein the high ventilation member is polyurethane foam subjected to membrane removal treatment. 6. The seat pad according to claim 5 , wherein the polyurethane foam has a density of 20 kg/m 3 to 40 kg/m 3 and a number of cells of 45 cells or less per 25 mm. 7. The seat pad according to claim 2 , wherein a thickness of the high ventilation member is 20% or more of a total thickness of the cushion pad and the high ventilation member at a position where the high ventilation member is embedded. 8. The seat pad according to claim 2 , wherein the high ventilation member is inserted in the cushion pad in a state of being compressed in a planar view lateral direction of the high ventilation member. 9. The seat pad according to claim 3 , wherein the high ventilation member is inserted in the cushion pad in a state of being compressed in a planar view lateral direction of the high ventilation member. 10. The seat pad according to claim 2 , wherein the high ventilation member is polyurethane foam subjected to membrane removal treatment. 11. The seat pad according to claim 3 , wherein the high ventilation member is polyurethane foam subjected to membrane removal treatment. 12. The seat pad according to claim 4 , wherein the high ventilation member is polyurethane foam subjected to membrane removal treatment. 13. The seat pad according to claim 7 , wherein the high ventilation member is inserted in the cushion pad in a state of being compressed in a planar view lateral direction of the high ventilation member. 14. The seat pad according to claim 7 , wherein the high ventilation member is polyurethane foam subjected to membrane removal treatment. 15. The seat pad according to claim 8 , wherein the high ventilation member is polyurethane foam subjected to membrane removal treatment. 16. The seat pad according to claim 9 , wherein the high ventilation member is polyurethane foam subjected to membrane removal treatment. 17. The seat pad according to claim 13 , wherein the high ventilation member is polyurethane foam subjected to membrane removal treatment. 18. The seat pad according to claim 17 , wherein the polyurethane foam has a density of 20 kg/m 3 to 40 kg/m 3 and a number of cells of 45 cells or less per 25 mm.
