Vehicle seat

A vehicle seat comprising:

• a seatback that supports a back portion of a vehicle occupant;
• a seat cushion that supports buttocks and femoral regions of the vehicle occupant;
• an airflow generating device that is disposed at an interior of at least one of the seatback or the seat cushion, that the airflow generating device being configured to:
• generate a difference in pressure between a supporting surface side that supports the vehicle occupant, and a side opposite the supporting surface;
• and
• generate an airflow;
• and
• a cushion layer that is provided in the seatback or the seat cushion and at a side at which the airflow generating device is disposed, that the cushion layer defining a portion of the supporting surface side at the side at which the airflow generating device is disposed, the cushion layer including:
• a main air permeable portion that is set to a predetermined void ratio and through which a majority of the airflow generated by the airflow generating device passes;
• and
• an auxiliary air permeable portion, which is set to a void ratio that is lower than that of the main air permeable portion and whose air permeability is lower than that of the main air permeable portion, wherein:
• the cushion layer is a single layer that is directly supported by a fabric spring member that extends between a pair of frame members that structure portions of a frame at a side of the seatback or the seat cushion at which the cushion layer is provided, and
• the fabric spring member has air permeability that is equivalent to, or higher than, that of the main air permeable portion.
