つた。"Problem to be Solved by the Invention" However, in such a conventional seatback frame 1, the clamping flange portion 3a of the plate frame member 2 sandwiches the pipe-shaped portion 5 of the pipe frame member 4 from the front and back, Since they are welded together, the configuration is such that it can sufficiently withstand loads in the front and rear directions, but the clamping flange portion 3a holds down the pipe-shaped portion 5 against loads in both directions. As a result, for example, the lower end of the pipe-shaped portion 5 swings and plays, and only the welded portion receives loads in both directions intensively. Therefore, in order to make the length of the welding part sufficiently long, it is necessary to extend the clamping flange part 3a upward and the pipe-shaped part 5 downward, which increases the weight of the product and increases the cost. There was a problem in that it caused an increase in the amount of water.

することを目的としている。 The present invention was developed by focusing on these conventional problems, and uses two welded parts spaced apart from each other in the vertical direction to receive loads from both sides. Eliminates the need to increase the size of parts, without increasing the product load,
The object is to provide a seat back flange portion that does not increase cost.

A reinforcing flange portion 24 facing inward is formed. Near the upper end 21 of the plate frame member 20, the spacing between the reinforcing flange parts 24 becomes gradually narrower, and a clamping part 25 is provided to sandwich the pipe-shaped part 32 of the pipe frame member 30 between its front and rear flanges 26. There is. The front and rear flanges 26 of the holding part 25 and the reinforcing flange part 24 are formed in a smooth continuous manner.

から挟むようにして抑え込む。 When a load is applied to the seatback frame 10 in the longitudinal direction, the 30 pipe-shaped portions 32 of the pipe frame member tend to swing back and forth. The pipe-shaped portion 32 that is about to swing back and forth is held down by the front and rear flanges 26 of the clamping portion 25 of the plate frame member 20 by sandwiching it from the front and rear.

み、十分に耐えることができる。 In other words, part of the load in the front and rear direction is applied to the front and rear flange 26 side, and part of the load is applied to the welded part between the front and rear flange 26 and the pipe-shaped part 32, so that the welded part does not receive concentrated load in the front and back direction. It can be tolerated well.

部２３との溶接部位が受ける。 When a lateral load is applied to the seatback frame 10, the pipe-shaped portion 32 and the front and rear flanges 26
The crushed portion 35, which is the lower end portion of the pipe frame member 30, tends to swing approximately around the welded portion with the pipe frame member 30. The welded portion between the lower edge 36 of the crushed portion 35 and the side surface portion 23 of the plate frame member 20 receives the moment load caused by the swinging.

との溶接部位が十分に耐えることができる。 The moment load is applied to the welded portion between the lower edge 36 of the crushed portion 35 and the side surface portion 23 of the plate frame member 20, so that the welded portion is sufficiently downward from the welded portion between the pipe-shaped portion 32 and the front and rear flanges 26. Because they are located at separate positions, the force is not large, and the force is transferred between the crushing portion 35 and the side surface portion 23 of the plate frame member 20.
The welding area can withstand sufficiently.
すなわち、横方向の荷重を、潰し部３５の下縁
３６と板フレーム部材２０の側面部２３との溶接

るようにしてもよいことはいうまでもない。 That is, the lateral load can be sufficiently absorbed by the welding area between the lower edge 36 of the crushed portion 35 and the side surface 23 of the plate frame member 20, and the welding area between the pipe-shaped portion 32 and the front and rear flanges 26. can be received. In the above embodiment, the pipe-shaped portion 32 of the pipe frame member 30 is only held between the flange portions 24, 24 in the holding portion 25, but the end of the plate frame member 20 may be It goes without saying that the holding part 25 may be formed in a part of the part.
