<p>The invention concerns an air filter device comprising: an air pipe line distribution frame (12), bearing a filtering medium (14), said frame (12) including at least two parts (12P, 12I, 12D) mutually connected by means articulating (P1, P2) about a substantially transverse axis (T1, T2), such that when said articulating means are operational, the frame (12) is deformable between a substantially planar reference configuration and at least a globally bent configuration; and means (32, 34) for limiting the bending of the frame (12) by limiting the relative angular displacement of the two parts of the frame about the articulation axis (T1, T2). The frame (12) is deformable in two bent configurations with opposite curvatures, called concave and convex. The means limiting the bending of the frame comprise first (32) and second (34) means for limiting respectively the concave and convex bending.</p> |
