Abstract

The apparatus consists of a grille (3) articulated in a frame along an axis for pivoting of the grille (3) corresponding to one of the sides of the latter, this grille (3) being fitted with bars (18) connected together by cross members (19), and in which the grille is divided, along its pivotal axis, into a middle portion (Z1) and two lateral portions (Z2) elastically connected to the middle portion (Z1), one end of the middle portion (Z1), contiguous to the pivotal axis, being intended to bear against a corresponding surface of the frame exerting a moment opposing the movement of the grille (3) about its pivotal axis. <IMAGE>
