Abstract

L'invention concerne une bielle comportant, à chacune de ses deux extrémités, une partie de liaison destinée à coopérer avec un organe extérieur, l’une de ces parties de liaison étant conformée en étrier (14) et l’autre de ces parties de liaison comprenant un œillet principal (1), ledit étrier (14) comportant deux œillets secondaires (3a, 3b) reliés chacun audit œillet principal (1) par un ensemble de bande de renfort (5) comprenant deux parties continues (5a, 5b) formant boucles autour dudit œillet principal (1) et respectivement autour de chacun desdits œillets secondaires (3a, 3b), lesdits œillets principal (1) et secondaires (3a, 3b) et ledit ensemble de bande (5) étant surmoulés au moins partiellement par une matière thermoplastique définissant notamment deux branches d’étrier (14a, 14b) comportant chacune l’un desdits œillets secondaires (3a, 3b). (Fig. 3)The invention relates to a connecting rod comprising, at each of its two ends, a connecting part intended to cooperate with an external member, one of these connecting parts being shaped like a stirrup (14) and the other of these parts connection comprising a main eyelet (1), said stirrup (14) comprising two secondary eyelets (3a, 3b) each connected to said main eyelet (1) by a set of reinforcing strips (5) comprising two continuous parts (5a, 5b) forming loops around said main eyelet (1) and respectively around each of said secondary eyelets (3a, 3b), said main (1) and secondary (3a, 3b) eyelets and said band assembly (5) being molded at least partially by a thermoplastic material defining in particular two stirrup branches (14a, 14b) each comprising one of said secondary eyelets (3a, 3b). (Fig.3)
