A vertical case 8 is continuously provided on the rear side of the blower case 6, and a branch portion 9 is formed at the rear end of the vertical case 8. The branch portion 9 is located below the buttocks of a seated person. The branch portion 9 is provided with left and right side cases 10 that extend below the front end of the seat so as to be positioned below the thigh of the seated person. The seat blower case 4 is provided with a blower cylinder projecting upward at a predetermined position.
Buttock vent 11, a thigh vent 12 at the base side of the side case 10, and tip vents 13, 13 at the tip side of the side case 10, respectively. P1 is a blown wind, P2 is a blown wind from the thigh blowout port 12, P3 is a blown wind from the tip blowout ports 13 and 13,
When P4, P1>P2>P3> P4.

The present invention is directed to a so-called bellows-shaped narrowing portion 16 which is widened vertically and horizontally between the buttocks ventilation port 11 and the thigh ventilation port 12 and between the thigh ventilation port 12 and the tip ventilation port 13 respectively.
Is provided. The throttle section 16 is formed by the principle of the orifice P1>
It works so that P2>P3> P4. A ventilation hole 18 penetrating vertically is formed in the cushion material 17 above each buttocks ventilation opening 11, and the cushion material 17 is formed through the ventilation hole 18.
Is blown through the skin member 19 surrounding the. Reference numeral 20 denotes a zigzag spring for supporting the cushion member 17. A blower case 21 for the backrest for the backrest has a blower case 23 provided with a blower 22 for the backrest blower, and a suction opening 24 formed on the rear surface of the blower case 23. A waist case 25 is continuously provided above the blower case 23, a back case 26 is formed above the waist case 25, and a shoulder case 27 is provided above the back case 26. Note that the waist case 25, the back case 26, and the shoulder case 27 are names given for convenience in describing the positional relationship, and the positions are not limited by these names. The blower case 21 for the backrest includes the waist case 2
5 is provided with a waist vent 30, the back case 26 is provided with a back vent 31, and the shoulder case 27 is provided with a shoulder vent 32, and the wind blown from the waist vent 30> the back vent The configuration is such that the air flow from the mouth 31> the air flow from the shoulder air outlet 32. In addition, the shoulder air outlet 3
2 and the back air outlet 31 are provided with mounting projections 35 protruding to the side, and the rear surface of the mounting projection 35 is formed such that the front and rear sides are thinner in the front-rear direction and thicker toward the base side. From the blower case 23
The fixing is completed by fixing the portion to the fixing portion. The lower back blower 22 has an opening at the lower end of the measurement tube 38 in the vertical direction, and the upper end of the measurement tube 38 is attached to a predetermined position of the backrest blower case 21. The measurement tube 38 is independent of the backrest blowing case 21, and a measurement suction port 39 is provided at the upper end of the measurement tube 38.
8, a humidity sensor 40 is provided inside the lower end. Although not shown, a ventilation hole 18 penetrating back and forth is also formed in the cushion member 17 of the backrest, and the cushion material 1 is inserted through the ventilation hole 18.
The air is blown through the skin member 19 surrounding the 7.

[0008]

Next, the operation will be described. The seat frame 1 and the backrest frame 2 are provided with a blower case 4 for the seat and a blower case 21 for the backrest, respectively, and the blower case 4 for the seat and the blower case 21 for the backrest have respective blowers. Since it is provided, the air blown from the air outlet passes through the skin member 19 and hits the occupant, thereby reducing stuffiness during sitting and improving the feeling of sitting. In this case, a buttock air outlet 11 is provided at a branch portion 9 of the seat blower case 4, a thigh air outlet 12 is provided at a base side of the side case 10, and the side case 1 is provided.
0, a front end blower port 13 is provided on the front end side, and the wind blown from the buttock blower port 11 is P1 and the thigh blower port 1 is provided.
P1>P2>P3>, where P2 is the wind blowing from P2 and P3 and P4 are the blowing wind from the front blower ports 13, 13.
Since it is configured to be P4, it is possible to sufficiently blow air to the buttocks blower opening 11 of the branch portion 9 that is hard to pass through the skin member 19 due to the load of the occupant, thereby reducing blower unevenness. Similarly, the backrest blower case 21 includes a waist blower port 30 in the waist case 25, a back blower port 31 in the back case 26, and a shoulder blower port 32 in the shoulder case 27.
Are provided, and the air flow from the waist air outlet 30> the air flow from the back air outlet 31> the air flow from the shoulder air outlet 32. Sufficient airflow can be secured even in the suction opening 24 that is difficult to pass through, and the seating feeling is improved. The shoulder air outlet 32 and the back air outlet 31 of the backrest air blow case 21 are provided with mounting projections 35 protruding laterally, and the rear surface of the mounting projection 35 has a thin front-rear thickness at the front end. Since the mounting projection 35 and the zigzag spring 20 are relatively moved to be engaged with the zigzag spring 20 from below, the blower case 23 is only fixed to the fixing portion. Thus, the mounting operation is completed, and the mounting operation is facilitated. Further, since the ventilation opening is provided on the front surface of the mounting protrusion 35, the ventilation can be improved by approaching the occupant. Therefore, the lower end of the measuring tube 38 in the vertical direction is opened in the backrest blower 22, and the upper end of the measuring tube 38 is attached to a predetermined position of the backrest blowing case 21. It is independent of the backrest blower case 21,
Since the measurement suction port 39 is provided at the upper end of the measurement tube 38 and the humidity sensor 40 is provided inside the lower end of the measurement tube 38, the humidity sensor 40, the seat blower 5 and / or the backrest are provided. When connected to the blower 22 for air blowing, the air volume can be controlled well.

[0009]

According to the present invention, a seat blower case 4 provided with a seat blower 5 is provided in a seat frame 1 of a seat, and a cushion member 17 and a skin member are provided on an upper surface side of a blower opening of the seat blower case 4. In the seat provided with the air blowing member 19 and the air blowing through the skin member 19, the air blowing ports are arranged side by side at predetermined intervals in front and rear, and the air blowing case 4 for the seat is provided.
The air-permeable sheet provided with a bellows-like narrowed portion 16 so that the air flow increases from the front air outlet to the rear air outlet, and the backrest frame 2 of the sheet is provided with a backrest airflow. In a sheet provided with a backrest blowing case 21 provided with a blower 22, a cushion member 17 and a skin member 19 provided on the front side of a blowing port of the backrest blowing case 21, and air is blown through the skin member 19, The blower ports are arranged vertically at predetermined intervals, and the backrest blower case 21 is provided with a bellows-like narrowed portion 16 so that the blower increases from the upper blower port to the lower blower port. Since the air-permeable sheet is provided, it is possible to sufficiently blow air to a load-bearing portion such as the buttocks and the waist, thereby improving the air permeability and improving the seating feeling.
