Abstract: A vehicle seat is provided which comprises a seat cushion, a seat back and a side support fixed to each side of the seat back. Each of the side supports has a recess formed in the rear thereof to allow space for the knees of a passenger sitting in a rear seat behind the vehicle seat of the present invention. Further, a gap may be formed between the side surface of the middle portion of the seat back and the middle portion of the side support and at least one groove may be formed in the seat back. The groove opens into the gap so that air in the interior of the vehicle may flow through the groove by way of the gap thereby cooling the back of the passenger sitting in the seat.
