Heated air cushion cover

A method for producing the heated air cushion cover, comprising the steps of:

• elastically stretching at least one second material layer and partially joining an air permeable third material layer to the elastically stretched second material layer,
• then relaxing the stretching of the second material layer so that the second material layer returns to an area smaller than that of the third material layer so as to create undulations in the third material layer which form airs spaces between the second and third material layers, air flowing into said spaces via perorations of the second material layer being able to pass through the air permeable third layer in a diffused manner, and
• then, partially connecting at least one first material layer to the at least one perforated second material layer in a manner forming at least one cavity through which a stream of air can flow from an air inlet opening and emerge from the at least one cavity through the perforations of the second material layer to the cavities between the perforated second material layer and the air permeable third material layer.
