Abstract

The projection screen according to the invention has a support frame formed by tubular inflatable elements 2 disposed along the periphery of the sheet 3 which form the screen. The screen can thus be folded for easy transportation when the elements 2 are deflated and the simple inflation of the elements 2 stiffens and stretches the screen 3. In an alternative embodiment a plurality of tubular elements are provided side by side, which project to one side. <IMAGE>
