本考案は自動車シート（座席）におけるシート
バツク（背凭部）のＳ形ばね固定構造に関するも
のである。[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to an S-shaped spring fixing structure for a seat back in an automobile seat.

造である。(Prior art and its problems) A seat bag using a back frame made of pipe whose sides are bent into a dogleg shape has a plurality of S-shaped springs stretched across the back frame in multiple stages in the horizontal direction. It has a structure in which a cushion body made of molded foam is supported by a spring, and these are covered with a skin.
以上の前記Ｓばねは夫々その端末をバツクフレ
ームの左右側部に溶接したクランプで固定してい
る。 The ends of each of the S springs described above are fixed to the left and right sides of the back frame by clamps welded to the left and right sides of the back frame.
ところで、前記バツクフレームは側面略く字状
に折曲されているため、このバツクフレームに前
記Ｓ形ばねを張架すると、バツクフレームの折曲
形状に沿つてＳ形ばねが固定される。 By the way, since the side of the back frame is bent in a substantially dogleg shape, when the S-shaped spring is stretched over the back frame, the S-shaped spring is fixed along the bent shape of the back frame.
従つて、バツクフレームの上部折曲部に張架し
たＳ形ばねは略座面形状になるが、下部折曲部に
張架したＳ形ばねはその上部側が前方に突出状に

する構造となり、Ｓ形ばね全面でクツシヨン体を
支持することができない。従つて、着座した場
合、斯るＳ形ばねの上部側が異物感となり、座り
心地が悪い不具合があつた。 Therefore, an S-shaped spring stretched on the upper bent part of the back frame has a substantially seat shape, but an S-shaped spring stretched on the lower bent part has its upper side protruding forward, and its lower side protrudes backwards. Therefore, the S-shaped spring stretched between the lower bent portions has a structure in which only the forwardly protruding upper part supports the cushion body made of foam, and the cushion body cannot be supported by the entire surface of the S-shaped spring. . Therefore, when the user sits on the seat, the upper side of the S-shaped spring feels like a foreign body, resulting in an uncomfortable seating experience.

面積が少ないなどの理由による）。 In addition, as a method to eliminate this problem, the clamp that fixes the S-shaped spring is not welded along the back frame, but is welded at an angle to the back frame (for example, welded to the upper bent part). It is possible to weld the clamp approximately parallel to the clamp. However, if the back frame is made of sheet metal with a certain thickness in the longitudinal direction, it is possible to weld the clamp in an inclined shape, but if the back frame is made by bending and forming the pipe, The clamp cannot be welded in any direction other than the horizontal direction, and the clamp cannot be welded at an angle to the back frame like a sheet metal back frame (due to the small welding area, etc.).

る不具合があつた。 In addition, Japanese Utility Model Application Publication No. 57-142949 discloses a structure in which a cushion body made of a foam is supported by the entire surface of an S-shaped spring between the left and right lower bent parts of a back frame made of a pipe whose sides are bent into a substantially dogleg shape. There are some disclosed. However, this is a structure in which both ends of the S-shaped spring are hooked to a holding member that is rotatably connected to a bracket welded to the frame.
The S-shaped spring moved, causing abnormal noise, and the overall length of the S-shaped spring was shortened by the length of the bracket and the holding member (in the width direction of the seat), resulting in a loss of cushioning properties.
そこで、本考案は斯様な従来品の不具合を除去
することを目的とする。 Therefore, the present invention aims to eliminate such defects of conventional products.

It is bent and fixed at both ends to clamps welded to the back frame. Therefore, such S
Both ends of the shaped spring are fixed to clamps welded along the lower bent portion of the back frame, and the portion excluding the fixed portion is bent so that the lower side is forward and the upper side is backward.
そのため、Ｓ形ばねの全面が発泡体製クツシヨ

単になる。(Effects) As mentioned above, the present invention has an S-shaped spring bent in the shape of the seat back surface stretched over the lower bent part of the pipe back frame whose side surface is bent into a substantially dogleg shape. The entire S-shaped spring supports the cushion body. Therefore, the shape of the seating surface of the cushion body is maintained, and the foreign body feeling caused by the S-shaped spring, which is the case with the conventional products, is eliminated, and the cushion body can be used comfortably. In addition, since the S-shaped spring only needs to be bent, its formability is good. Furthermore, since the present invention fixes both ends of the S-shaped spring to clamps welded directly to the frame, the S-shaped spring
The entire shaped spring is fixed and no abnormal noise occurs. In addition, since it is possible to use an S-shaped spring that has a longer overall length by the length of the bracket and the holding member (in the width direction of the sheet) than the conventional product, cushioning properties are improved, and the S-shaped spring is used for the holding member, which is a movable member. Since the spring can be fixed to the clamp fixed to the frame without having to hook both ends of the spring, the work of installing the S-shaped spring becomes easier.
