Abstract
Abstract A ventilated back-seat rest particularly for automotive vehicles is described comprising a panel formed with air passageways open at the side thereof contacted by the occupier of the chair or seat, and a conduit conducting air to the air passageways. The air conduit is preferably a tube leading to the vicinity of the center of the panel, and the air passageways are open channels formed according to a spiral formation starting from the center of the panel and leading to its outer edge. To enable its use in automotive vehicles, one described embodiment includes an air-funnel attachable to the exterior of the automotive vehicle and connected to the free end of the air conduit for conducting air thereto, and a second described embodiment includes a connection for connecting the free end of the air conduit to the ventilating fan of the automotive vehicle.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
193 words
A body supporting device for use as a chair back rest or seat rest, comprising: a panel of molded plastic material formed with a spirally-extending corrugation defining a spiral channel open at the upper face of the panel and a spiral channel open at the under face of the panel; and an air conduit extending along the under face of the panel from the outer periphery of its spiral channel to the center thereof; one end of the conduit being connected to a source of air, and the opposite end of the conduit being connected to an opening passing through the panel at the center of the spiral channels to conduct the air to the upper face of the panel; whereby, when the device is occupied by an occupier contacting the center of the upper face of the panel, the center of the open spiral channel at the upper face of the panel is covered by the occupier and the air is directed along the upper face spiral channel in direct contact with the occupier and escapes from the channel at the outer edges of the panel where not contacted by the occupier.
