Abstract

Logement pour joint à rotule, dont on peut réduire le coût de production et qui peut facilement offrir la robustesse souhaitée. Le logement (7) comporte un premier corps (11) de logement ayant une section d'agrafage (10) qui est soumise ensuite à l'agrafage. Un second corps (12) de logement est disposé d'une seule pièce à la périphérie extérieure du premier corps (11) de logement. Le premier corps (11) de logement est fait d'une matière à allongement élevé, qui supporte facilement un agrafage. Le second corps (12) de logement est fait d'une matière à faible allongement, qui est moins susceptible d'allongement que la matière précédente.
