Abstract (en)

The ventilation grid is intended to be inserted between an internal space and a space which is likely to be subjected to weather effects and comprises a plate or a metal sheet (1) in which there are openings (3) having the general shape of an elongate rectangle and separated by solid elongate lengths (7) of the plate or metal sheet (1). Each rectangular opening (3) is covered on the outside by a rectangular bridging piece (4) placed at a distance d from the surface of the plate, which distance is much less than the width of the rectangular openings and the bridging piece (4) is connected in a progressive manner in all directions to the plate (1) by a connection part of generally inclined shape (4a, 4b). Application to ventilation elements protected so as to prevent powder snow from coming in. <IMAGE>
