ABSTRACT:
A two part ventilated seat cover for a motor vehicle seat, comprising a seat portion cushion and a seat back cushion. The two cushions are separated and mutually attached by a bulkhead. The bulkhead prevents air flow between the respective cushions. The cushions are equally sized to help equalize air flow thereto and therefrom. Elastic straps are provided to each cushion to facilitate attachment to the vehicle seat. Air is drawn into the system through an air pick up, then passes through a flexible conduit which branches into two secondary conduits. Each secondary conduit is preferably of equal cross section, each supplying one cushion with equal air flow. Each cushion is perforated only at a respective surface contacting the user, and air is discharged therethrough. Adequate supply of air to each respective cushion is assured by the branched supply conduit, and by separation of air flow within the respective cushions, as effected by the bulkhead. In alternative embodiments, air is obtained from the vehicle ventilation system and from a self-powered fan. In the latter case, the fan is integral to the air pick up.
