When vehicle seats are covered with a synthetic plastics material there are problems in hot weather because they do not soak up perspiration as would natural leather. On long journeys or on hot days, therefore, passengers clothes in contact with such seat coverings tend to become wet with perspiration. This is mitigated according to the invention by using the seat cushion as a pump which expells air as it is depressed by the movements caused by the person sitting on the seat or vehicle movements and the expelled air is forced out through the front face of the back rest of the seat. Air is also sucked in through the top face of the seat cushion at times when the seat cushion becomes less depressed. In this way a flow of air is provided between the passenger and the seat which removes perspiration. |
