- a vehicle seat 10 includes a seat cushion 20, a seat back 30, and a seat back 30.
- the headrest 40 provided at the upper part also has an equivalent force.
- the seatback 30 retains the seat shape and covers the surface of the pad 31 which functions as a cushioning material with a breathable cover.
- the cover 32 is covered with a pad 32, and the surface of the cover pad 32 is further covered with a skin material 33.
- FIG. 2 shows the seat back 30, the surface of the pad 31 is similarly covered with a cover pad 32 and a skin material 33 for the seat cushion 20.
- the pad 31 and the cover pad 32 are collectively referred to as a "sheet pad 34".
- a plurality of air holes 33a are formed on the surface of the skin material 33, and as shown in FIG. 2, each air hole 33a is connected to an air outlet 61C on the surface of the duct 60C.
- FIG. 3 is a perspective view showing a skeletal structure of the vehicle seat 10 on the side of the seat cushion 20, and FIG. 4 is a perspective view of the vehicle seat 10 as viewed from a lower surface side.
- the frame structure on the side of the seat cushion 20 includes a pair of left and right seat rails 21, a pair of left and right seat frames 22 attached to the seat rail 21, a seat spring 23, and a pan frame 24 bridged over the front of the seat frame 22. It is schematically configured.
- the blowers 50A and 50B for the seat cushion 20 are One at the front and one at the bottom.
- the duct 60A connected to the blower opening of the front blower 50A passes through an opening provided in the pan frame 24, reaches the upper surface of the pan frame 24, and branches in two directions, left and right.
- high elastic modulus member 70 a member having a higher elastic modulus than the elastic modulus of the seat pad 34 (pad 31 and cover pad 32) constituting the seat cushion 20 is provided between the duct 60A and the seat cushion 20. 70 (hereinafter, referred to as “high elastic modulus member 70”).
