US Patent 10322653 Vehicle seat fan apparatus and vehicle seat

A vehicle seat fan apparatus includes a fan including an impeller and a fan opening, the fan being attached to a vehicle seat at a position where an opening of an air passage provided on a back surface of a seat pad faces the fan opening; and a seal member configured to be interposed between the opening of the air passage and the fan opening, and to form an airflow path that allows airflow to move between the opening of the air passage and the fan opening. A release path is provided in a connection portion where the seal member is connected to the opening of the air passage, so as to allow part of the airflow to move between an inside and an outside of the airflow path, and between an inside and an outside of the air passage.
