Abstract: front page image
(EN)Provided are a chair frame structure and a manufacturing method thereof, with which no dependency on welding is present, assembly workability is good, a reliable strength may be obtained, and it is possible to minimize manufacturing costs. A gas receiving platform (30), in which a leading end part of a gas spring is inserted and makes contact, is attached to a seat base (17) of a seat main body (4). The gas receiving platform (30) is attached to the seat base (17) in a plurality of sites by blind rivets (45, 45), with an operation from therewithout. The gas receiving platform (30) is attached by the blind rivets without relying on welding, allowing obtaining set structure showing sufficient strength while having a simple structure, which is highly workable and inexpensive.
(FR)Cette invention concerne une structure de cadre de chaise et son procédé de fabrication dans lequel n'intervient aucun procédé de soudure, l'aptitude au façonnage est bonne, la résistance fiable et les coûts de fabrication sont réduits au minimum. Une plateforme de réception d'un gaz (30), dans laquelle une extrémité d'une source de gaz est insérée et forme un contact, est fixée à la base de l'assise (17) d'un corps principal (4). La plateforme de réception du gaz (30) est fixée à la base de l'assise (17) en plusieurs sites par des rivets aveugles (45, 45). La plateforme de réception du gaz (30) est fixée par les rivets aveugles sans soudure, ce qui permet d'obtenir une structure simple et d'un seul tenant, suffisamment solide, très facile à façonner et peu coûteuse.
(JA) 溶接に依存することがないと共に組立作業性が良く、確実な強度が得られ、しかも製造コストを低減することができる椅子のフレーム構造及びその製造方法を提供する。 座受け本体(4)の座受けベース(17)には、ガススプリングの先端部が挿入されて当接するガス受け台(30)が取り付けられる。ガス受け台(30)は、座受けベース(17)に対して、外側からの操作で、複数箇所でブラインドリベット(45、45)によって取り付けられる。溶接に頼ることなく、ブラインドリベットによって取り付けられているので、簡単な構造でありながら十分な強度を示し、且つ高い作業性で低コストで座受け構造を得ることができる。
