ツクフレーム構造に関するものある。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to frame structures such as reclining seats, and in particular, aims to maintain a predetermined strength and simplify the manufacturing process in seat back frames made of steel pipe frames. There are some related to the seat back frame structure.
従来、この種の鋼管フレームにおけるシートバ

着した構造のものが一般的であつた。 Conventionally, as shown in FIG. 1, the seat back frame of this type of steel pipe frame has been formed by connecting a main frame 10 and a lower frame 11 by welding or the like, and forming a hinge part 12 by crushing one end of the main frame 10. As shown in Fig. 2, steel pipes are generally bent and connected at the upper part with a connecting bracket 13, and the hinge part 14 is a separate bracket fixed by welding or the like. It was hot.
しかしながら上記前者の例ではメインフレーム
１０とロアフレーム１１との連結部の捩り強度が
弱く、後者の例では捩り強度は十分に保持してい
るが溶接等の加工工数及び部品点数が増えるため
コスト高になる等の欠点があつた。 However, in the former example above, the torsional strength of the connection between the main frame 10 and the lower frame 11 is weak, and in the latter example, although sufficient torsional strength is maintained, the cost is high because the number of processing steps such as welding and the number of parts increases. There were some drawbacks such as:

得られなかつたり、溶接工数が多い等の欠点を有
していた。 In other words, in the structure of the seatback frame,
Among the four sides forming the frame, one side A to which the reclining device mounting bracket 15 is fixed;
One side B of the lower frame 11 and the bracket 15
The two points a and b adjacent to one side A to which the is fixed are important in terms of strength, but the conventional example described above has drawbacks such as not being able to obtain satisfactory strength and requiring a large number of welding steps.
この発明は、上述した従来例の欠点を改善する
ためになされたものであり、殊に鋼管フレームの
シートバツクフレームにおいて所定の強度を保持

ある。 The present invention has been made in order to improve the above-mentioned drawbacks of the conventional example, and particularly to provide a seat back frame structure that maintains a predetermined strength in a seat back frame made of a steel pipe frame.
以下、この発明による実施例を第３図ないし第
４図にもとづいて具体的に説明する。第３図はこ
の発明による一実施例を示すシートバツクフレー
ムの構造であり、フレーム１は１本の鋼管を折曲
加工して所定の四辺形を形成する。 Hereinafter, embodiments of the present invention will be described in detail with reference to FIGS. 3 and 4. FIG. 3 shows the structure of a seat back frame according to an embodiment of the present invention, and the frame 1 is formed by bending a single steel pipe to form a predetermined quadrilateral.
このとき、フレーム１の一端に潰し加工により
ヒンジ部２を形成するとともに、他端は所定の位

用のブラケツトであり、フレーム１の所定の一辺
に溶着される。 At this time, the hinge portion 2 is formed at one end of the frame 1 by crushing, and the other end is abutted and welded at a predetermined position. Reference numeral 3 designates a bracket for the reclining device, which is welded to a predetermined side of the frame 1.
第４図は、この発明による他の実施例を示す要

強度にも強い等の効果を奏する。 As explained in detail above, according to the present invention, the frame 1 constituting the seat back frame
is made by bending a single steel pipe to form a specified quadrilateral shape, reducing the number of parts, and simply crushing the hinge part at one end of the frame and butting and welding the other end. The manufacturing process is simplified and costs are reduced. Furthermore, since the part of the seat back frame that is most concerned about its strength is formed from a single steel pipe, it has the advantage of high torsional strength.
