Abstract (en)
[origin: EP1156277A2] The device has a flap (2), with a contour that corresponds to that of the air intake channel (1) and pivots on an axle (7) transverse to the air flow direction (5,6). A safety element (10) fixed at an outer wall (8) of the air intake channel that becomes flexible when heated. A holder connection is formed between the flap and the outer wall by the safety element, so that the flap is in an open position that does not hinder air flow. The rigidity decrease of the safety element is determined so that the holder connection is released when the surrounding temperature exceeds a given threshold. When the holder connection is released, the flap pivots to a closed position to prevent air flow.
