Abstract

L'invention concerne un dispositif de liaison articulée d'un balai d'essuie-glace (10) dans une construction de barre plate, doté d'un bras d'essuie-glace (30) selon le principe du verrouillage latéral. Une broche de palier (38) faisant saillie latéralement sur le bras d'essuie-glace (30) et s'étendant transversalement par rapport à la direction longitudinale est montée de manière à pouvoir pivoter dans un élément de raccordement (16) fixé sur le balai d'essuie-glace (10). Ledit élément de raccordement comporte sur la face tournée vers le bras d'essuie-glace (30) un doigt de retenue (24) relié à celui-ci de manière décalée en direction de l'extrémité côté entraînement du balai d'essuie-glace (10) par l'intermédiaire d'un élément pont (28) à une certaine distance latérale de l'élément de raccordement (16) et vient en prise depuis la face tournée vers une réglette d'essuie-glace (12) avec le bras d'essuie-glace (30). Le doigt de retenue (24) présente un bec (26) faisant saillie par rapport à sa face frontale tournée vers la broche de palier (38) et comprenant une surface de butée (56) orientée vers la réglette d'essuie-glace (12). Ladite surface de butée coopère avec une autre surface de butée (54) située dans la zone de pivotement relative par rapport au bras d'essuie-glace (30) et prévue sur le bras d'essuie-glace (30). Les deux surfaces de butée (54, 56), dans la position de fonctionnement du balai d'essuie-glace (10), forment entre elles un angle de pivotement (a), dans la zone duquel un démontage ou un montage en direction de la broche de palier (38) n'est pas possible.
