Abstract

La présente invention concerne un nouveau cadre de dossier de siège et un siège utilisant celui-ci qui résolvent un ou plusieurs problèmes comprenant une augmentation du nombre de composants, le risque d'assemblage erroné et une réduction de l'efficacité de travail. Un cadre de dossier de siège (10) est constitué de résine synthétique. Il est intégralement formé dans le cadre de dossier de siège (10) des sections de guidage-ajustement en résine (30, 31) pour ajuster un guide de résine côté verrouillage (12) dans lequel un montant (11a) d'un appuie-tête, et une section de guidage de montant (32) dans laquelle l'autre montant (11a) de l'appuie-tête est inséré. En raison de cette configuration, un guide de résine côté libre peut être omis, ce qui permet d'obtenir un ou plusieurs effets tels que la réduction du nombre de composants, la réduction du risque d'assemblage erroné, et/ou l'amélioration de l'efficacité de travail d'assemblage.
