この考案は、車両用座席のストラツプベルトに
関する。[Detailed description of the invention] (Industrial application field) This invention relates to a strap belt for a vehicle seat.
（従来の技術）
車両用座席のストラツプベルトは、座席クツシ
ヨン体を表皮材で覆う際に、表皮材がクツシヨン
体の表面に沿うように座席裏側で表皮材を引つ張
るものである。(Prior Art) A strap belt for a vehicle seat is a belt that, when covering a seat cushion body with a skin material, stretches the skin material on the back side of the seat so that the skin material follows the surface of the cushion body.
ところで従来のストラツプベルトは、錆ないこ
と等からゴム製のものが好んで用いられている。
またその断面形状は、略楕円形からなつている。 By the way, conventional strap belts are preferably made of rubber because they do not rust.
Moreover, its cross-sectional shape is approximately elliptical.

ヨン体に正しく沿わせられない問題がある。 However, rubber strap belts
When attaching the skin material to the cushion body, steam is used to smooth out the wrinkles in the skin material or to activate the adhesive, so the heat softens it significantly and weakens the pulling force on the skin material. , there is a problem that the skin material cannot be properly aligned with the cushion body.

りストラツプベルトの耐久性が劣る問題もある。 Furthermore, the rubber that can be used for rubber strap belts has a Shore A hardness of less than 80°, which makes them soft and easily twisted, and the surface has a large sliding resistance, making it difficult to work with. Furthermore, the twisting and sliding resistance tend to cause uneven elongation during use, and there is also the problem that the durability of the strap belt is poor due to large permanent elongation and creep of the rubber itself.

るベルト状としたことを特徴とするものである。(Means for Solving the Problem) This invention provides a strap belt for a vehicle seat for pulling the skin material along the surface of the cushion body when covering the seat cushion body with the skin material. It is characterized in that a thermoplastic urethane elastomer having a Shore A hardness of 80 to 95 degrees is made into a belt shape with a substantially circular cross section.

トを軽くすることができる。(Function) Thermoplastic urethane elastomer has excellent heat resistance, so it is difficult to be softened by steam when the skin material is applied, and the skin material can always be stretched along the cushion body. In addition, since it is made of urethane elastomer with a Shore A hardness of 80 to 95 degrees, it is not too soft.
In addition, since the strap belt is circular in cross section, it is difficult to twist the strap belt, and the sliding resistance on the surface is low, making it easier to work when applying the skin material. Furthermore, the elongation of the strap belt becomes uniform due to the resistance to twisting and low sliding resistance, and since the urethane elastomer has low permanent elongation and low creep, the durability of the strap belt becomes good. Moreover, the tensile strength of urethane elastomer with Shore A hardness of 80 to 95° is 250 to 600 Kg/cm 2 (JIS-
K-6301) and has a tensile strength that is 2 to 4 times higher than that of rubber that can be used as strap belts, so the cross-sectional area of strap belts can be reduced by more than 30% compared to rubber ones, making strap belts easier to use. It can be made lighter.

A thermoplastic urethane elastomer with an angle of 80 to 95 degrees is injection molded into a belt shape with a substantially circular cross section. Also, the knotted portions 16 formed at predetermined portions are engaged with a frame on the back side of the cushioned body when the skin material is attached to the cushioned body, and the strap belt is pulled into a tensioned state. It is meant to be maintained. On the other hand, the hooking tool 14 is for hooking the strap belt 10 onto the skin material, and is used to hook the strap belt 10 onto the skin material.
It is made of a wire formed into a predetermined shape, partially penetrated through the end of the wire, or other clips.

量性に優れる効果もある。(Effects) In this invention, a thermoplastic urethane elastomer having a Shore A hardness of 80 to 95 degrees is made into a strap belt having a substantially circular cross section. Therefore, the strap belt is less susceptible to softening due to heat and can always keep the skin material stretched along the cushion body. In addition, since it is difficult to twist and the sliding resistance on the surface is low, the strap belt slips easily when pulling the skin material, making the work easier. Furthermore, it also has the effect of being excellent in durability and light weight.
