ABSTRACT:
A ventilated seat cushion, especially for use on automobile seats, has a pair of cushions connected by a flexible hinge. In each cushion, a grid-like framework of upstanding support ribs includes a pad situated at the bottom of each of the rib intersections, and apertures are formed in the upper edge of each rib between rib intersections to afford fore and aft and transverse channels for the free circulation of air. A stiffening marginal band is attached to the periphery of the grid-like framework and a foraminous fabric cushion cover overlies the grid framework and marginal band. Conventional binding secures the cushion cover to the marginal band. Ventilation is provided by air movement not only in fore and aft and transverse directions through the apertured portions of the grid framework but also into and out of the cushion through the mesh-like fabric cover.
