Problems solved by technology

[0004] However, in Patent Document 1, when the lower surface of the forward portion of the backrest support bar abuts against the corners of the upper surface of a low-position floor placed object, the placed object or the back bar itself will be damaged. Installing the cover on the back support bar will increase the number of parts and the installation work will be cumbersome
[0005] In Patent Document 2, the structure of the cover itself is relatively complicated, which increases the manufacturing cost

Abstract

A chair configured such that a backrest support rod does not make contact with an object when the chair is swiveled and is thus reliably prevented from damaging the object or from being damaged by the object and that the chair uses a reduced number of parts, has a simple structure, and can be easily assembled. A chair, wherein front portions of front facing sections (9b) of a backrest support rod (9) are mounted to a support base (5) supported by a leg body (3) and supporting a seat (7). The backrest support rod (9) is formed in an L-shape in a side view and comprises upwardly facing raised sections (9a) and the forwardly facing front facing sections (9b). The upwardly facing raised sections (9a) and the forwardly facing front facing sections (9b) are connected together through a curved section (9c), and the raised sections (9a) support a backrest (6). A protective cover (11) covers at least that portion of the backrest support rod (9) which extends from the rear surface of the curved section (9c) to the lower surface thereof.

Description

Technical field [0001] The invention relates to a chair with a backrest supporting rod in a substantially L-shaped side view. Background technique [0002] The backrest support rod of the conventional chair is generally L-shaped in side view. The upright part facing upward and the forward part facing forward are connected to each other by a curved part. When the chair rotates, etc., in order to prevent the back rod, that is, the backrest support rod When contacting other articles, the article or the back rod itself is damaged. A cover made of a soft material is used to cover the back and outer sides of the back rod (for example, refer to Patent Document 1: Japanese Patent Laid-Open Publication No. 2002-136388 ). [0003] In addition, the joint part of the leg frame and the back frame is covered by the joint part cover, and the joint part cover allows the two covering parts to open and close each other through the hinge part (for example, refer to Patent Document 2: Japanese Patent...
