Description

Ventilated Vehicle Seat
BACKGROUND OF THE INVENTION 1 . Field of the Invention
The present invention relates generally to the art of vehicle seating and more particularly to ventilated seating wherein air may be forced upwardly from the seating surface or draw downwardly therethrough to enhance occupant comfort. More specifically, the present invention relates to a ventilated seat which is easy to adapt to a wide variety of seating designs.
2. Description of Prior Art Many different types of ventilated seats are known to the art. They typically are designed to enhance occupant comfort by passing air through the covering of the seat or horizontally through the seat itself. In warm weather conditions the airflow moves in the vicinity of the seat contacted by the occupant's body and assists in cooling and reducing sweating. In cold weather conditions, ventilated seats can help warming the occupant if heated air is forced through the seat or the seat covering. It is known therefore, that airflow in ventilated seats can be in either direction.
