リフター付シートフレームに関する。DETAILED DESCRIPTION OF THE INVENTION (Industrial application field) The present invention relates to a seat frame of a seat cushion in an automobile seat (seat), more specifically, a front frame member and a rear frame member, and a front frame member and a rear frame member connected to each other. The present invention relates to a seat frame with a lifter including left and right frame members.

れている。(Prior Art) Conventionally, a front and rear frame member and left and right frame members are welded in a frame shape to form a frame-shaped seat frame, for example, in Japanese Utility Model Laid-Open No. 61-102149. As disclosed in Japanese Patent Publication, a linear front and rear frame member,
It is composed of U-shaped left and right frame members. And
Each frame member is formed by pressing into a U-shaped cross section, an L-shaped cross section, or the like.

ムを製造できない不具合があった。(Problems to be solved by the invention) The above conventional seat frame (for example, a seat frame with lifter) has a long total length to form a frame having a different length in the front-rear direction (for example, a long length). It is necessary to newly form the right frame member, and weld the front and rear frame members of the seat frame to the left and right frame members having a long overall length. Therefore, in order to form a seat frame having different lengths in the front-rear direction, particularly a seat frame having a movable member of a lifter below, it is necessary to form an uneven bottom surface, and the left frame member and the right frame member are respectively formed. Must be molded separately. Therefore, it is necessary to manufacture two press dies for the left and right frame members each time, and there is a problem that the seat frame cannot be manufactured at low cost.

そこで、本考案は前後方向の長さ（全長）が異なる複数

In the frame, inclined connecting portions along the movable member of the lifter are provided on the front frame member side of the left and right frame members, while the left and right ends of the front frame member are integrated with the connecting portions of the left and right frame members. A bent portion to be welded to the bent portion is extended, and between the left and right bent portions, there is integrally formed an extended portion having a length in the direction of the rear frame member with respect to the bent portion. It is characterized in that fixing parts to be welded are provided on the left and right sides of the parts at the rear of the connecting parts of the left and right frame members.

型で成形できる。Therefore, since the front frame member has a structure in which the total length of the seat frame is adjusted, the left and right frame members are welded integrally with the front frame members having different lengths in the front-rear direction, and thus the seats having different total lengths are formed. The frame is manufactured. Therefore, the left and right frame members and the rear frame member can be shared, and since only the front frame member needs to be press-molded, the conventional product can be molded with one press die.

In the seat frame formed by connecting the left and right frame members that connect the front and rear frame members, the front frame member adjusts the longitudinal length of the seat frame. Therefore, by using front frame members having different lengths in the front-rear direction, seat frames having different total lengths can be formed. Therefore, by producing a press mold having only the front frame member and manufacturing only the front frame member, seat frames having different lengths can be manufactured. Therefore, as compared with the conventional product, it can be manufactured at a low cost.

ない。Further, between the left and right bent portions of the front frame member, an extended portion having a longer length than the bent portion is provided, and the left and right ends of the extended portion are welded to the rear of the connecting portion of the left and right frame members. Since the fixed portion is extended, the load is not concentrated on the welded portion between the bent portion of the front frame member and the connecting portions of the left and right frame members, and the welded portion is not separated. Further, the lifter mounting portions of the left and right frame members are reinforced by welding to the left and right frame members of the fixed portion, the operation of the lifter is ensured, the rigidity of the entire frame is improved, and the lifter may be deformed even when mounted. There are few.
