Abstract

Ensemble vis-écrou (1) pour un élément de siège de véhicule (100), comprenant :- une vis (2), - un écrou (3) comportant : --une portion de fixation (31) recevant intérieurement ladite vis (2), -- deux portions taraudées (32), configurées pour coopérer avec la vis (2), -- deux portions de liaison (35), reliant chacune une portion taraudée (32) à ladite portion de fixation (31), -- un élément ressort (36) venant contraindre chacune des portions taraudées (32) en direction de la vis (2).L’écrou (3) est configuré de sorte à permettre aux deux portions taraudées (32) de s’écarter l’une de l’autre contre l’effet dudit élément ressort (36), jusqu’à autoriser le déplacement en translation de la vis (2) par rapport à l’écrou (3) selon l’axe (A3) de l’écrou (3), lorsque un effort (F) selon l’axe (A2) de la vis (2) dépassant une valeur (FS) est appliqué à ladite vis (2). Figure d’abrégé : figure 2Screw-nut assembly (1) for a vehicle seat element (100), comprising: - a screw (2), - a nut (3) comprising: - a fixing portion (31) internally receiving said screw (2) ), - two threaded portions (32), configured to cooperate with the screw (2), - two connecting portions (35), each connecting a threaded portion (32) to said fixing portion (31), - a spring element (36) which forces each of the threaded portions (32) in the direction of the screw (2). The nut (3) is configured so as to allow the two threaded portions (32) to move away from one another on the other hand against the effect of said spring element (36), to allow the translational movement of the screw (2) relative to the nut (3) along the axis (A3) of the nut ( 3), when a force (F) along the axis (A2) of the screw (2) exceeding a value (FS) is applied to said screw (2).
