Abstract
Abstract A seat is mounted on an engine covering panel to form a clearance between a seat portion of the seat and the panel. The clearance is fluidly connected to a portion where an air flow produced by an engine cooling fan is present, thereby causing generation of air flow in the clearance to cool the seat portion.

Claim 4
Dependent Claim
49 words
A motor vehicle as claimed in claim 2, further comprising two wall members which are attached to respective sides of said seat to enclose said first clearance, said wall members having rear extensions which lead to the front bent portion of said cover member to enclose said second clearance.
