JPH05111419A - Seat cushion for automobile - Google Patents

Abstract

PURPOSE:To reduce a discomfort feeling caused by perspiration by holding the part in which a driver's body comes into contact with a seat cushion, in a dry state by a forced ventilation action. CONSTITUTION:Air fed out by an air conditioner 9 provided in an automobile is guided to a space 4 in a seat cushion through a duct 10. Also, by exhausting it to the part 7 which comes into contact with a driver's body by holes in several parts opened on its surface 11, ventilation of air in this part is executed forcibly. Moreover, when a tube 12 is installed in the inside of the space 4 in the seat cushion, and holes 13 for exhausting air opened on the surface of its tube, the same effect is obtained. In that case, when cloth of the cushion surface 14 having good gas permeability is used, the holes on the surface can be abolished and it is possible to improve the external appearance. Accordingly to such a configuration, a discomfort feeling in the part in which a driver's body sitting down on a seat of the automobile comes into contact with the seat by his perspiration is reduced.
