た。(Prior art) A conventional seat frame has a mold frame A made of thermoplastic synthetic resin or a thin metal plate, a hanging part D formed on the side of the mold frame, and a foamed urethane resin on the top of the frame A. A cushion material B such as the above was polymerized and the outer peripheral surfaces of the cushion material B and the frame A were integrally covered with a skin C.

が記載されている。 Conventionally, in Japanese Utility Model Publication No. 52-44167, the upper plate is a spring frame made of an elastic plate that deforms under the load of a thermoplastic synthetic resin, and the lower plate is also an elastic plate that deforms under the load of the thermoplastic synthetic resin. The spring frame and the frame are vertically spaced apart from each other, the left and right sides of the spring frame are formed in the hanging part, the front and rear sides of the spring frame are also formed in the hanging part, and the front and rear It is described that the lower end of each hanging part is joined by a perforated lower plate.
（発明が解決しようとする問題点）
しかしながら、前記公知例のものは、型のフ
レームの側部が垂下部Ｄのため、ウレタンＢを厚
くしないと、良好なクツシヨン性が得らない。ま
た、車輛用シートは一定の高さを必要とするが、
単にフレームＡの側部の垂下部Ｄのみを高くする
ことは耐久性の問題からできないので、ウレタン
Ｂの厚さを厚くしていた。したがつて、公知のも
のは、ウレタンＢが高価なため、シート全体のコ
ストが高くなつていた。(Problems to be Solved by the Invention) However, in the known example, since the side portion of the frame of the mold has a drooping portion D, good cushioning properties cannot be obtained unless the urethane B is made thick. Also, vehicle seats require a certain height,
Since it is not possible to simply increase the height of the hanging portion D on the side of the frame A due to durability issues, the thickness of the urethane B was increased. Therefore, since urethane B is expensive in known sheets, the cost of the entire sheet is high.
また、実公昭52―44167号公報に記載されたも
のは、上板と下板とが、共に、荷重によつて変形

ができない。 In addition, in the device described in Japanese Utility Model Publication No. 52-44167, both the upper plate and the lower plate are formed as elastic plates that deform under load, and the front, rear, left and right structures of the hollow part are formed almost vertically. Therefore, especially when looking at the lower plate as a reference, both the left and right sides simply stand up from the ends of the lower plate, causing problems in the robustness of the frame. In addition, an air vent hole is formed in the lower plate, and since the hollow part is not formed in a sealed air compression chamber, no air compression effect due to the hollow part can be expected. .

としたものである。(Means for solving the problem) Therefore, the present invention has a spring frame 4 in which the upper plate is made of an elastic plate that deforms under the load of the thermoplastic synthetic resin, and the lower plate deforms under the load of the thermoplastic synthetic resin. The spring frame 4 and the skeleton frame 5 are vertically spaced apart from each other, and the left and right sides of the spring frame 4 widen outward as they reach the lower end. In the hanging portion 9, the front and rear sides of the spring frame 4 are formed with hanging portions 11 that expand outward as they reach the lower end, and the left and right sides of the skeleton frame 5 have hanging portions 1 that expand outward as they reach the lower end.
0, both front and rear sides of the skeleton frame 5 are formed with hanging portions 12 that widen outward as they reach the lower end, and the lower ends of each of the hanging portions are hermetically joined to form a sealed air compression chamber 6. A thin cushion material 7 is superposed on the upper surface of the spring frame 4 in the sealed air cushion chamber 6.
This is a sheet frame whose upper surface is covered with a skin 8.

is a frame for seats, which can be blow molded.
Made of thermoplastic synthetic resins such as PP, PE, ABS, PVC, polycarbonate, ionomer, and nylon. The seat frame 1 is formed by blow molding, and the thermoplastic synthetic resin is molded into molds 2 and 3.
During this period, the material is extruded by an extruder, expanded to a certain size while blowing air, cooled, and then taken out from the molds 2 and 3 to form the material.

アークツシヨン室６を有して形成する。 Thus, the seat frame 1 has an upper plate formed as a spring frame 4 and a lower plate formed as a skeleton frame 5,
A sealed air compression chamber 6 is formed between the spring frame 4 and the skeleton frame 5.

２に形成する。 The left and right sides of the spring frame 4 are formed with hanging parts 9 that widen outward as they reach the lower end, and the front and rear sides of the spring frame 4 are formed with hanging parts 11 that widen outward as they reach the lower end. Further, the left and right sides of the skeleton frame 5 are formed with hanging portions 10 that expand outward as they reach the lower end, and the front and rear sides of the skeleton frame 5 are formed with hanging portions 10 that expand outward as they reach the lower end.
Form into 2.

い。 Thus, the seat frame 1 is integrally formed by joining the lower ends of each of the hanging parts, thereby forming the spring frame 4 into an elastic plate that moves up and down depending on the load. The skeletal frame 5 is formed of an inelastic plate that does not deform even when a load is applied, and has an immovable structure. The spring frame 4 and the skeletal frame 5 may be made of the same thermoplastic synthetic resin, or may be made of different thermoplastic synthetic resin materials, and the spring frame 4 and the skeletal frame 5 may have the same thickness. Parisons may be used or blow molded using parisons of different thicknesses.

ム１の外面は表皮８により一体的に包囲する。 A thin cushion material 7 is then placed on top of the spring frame 4. A sealed air compression chamber 6 between the spring frame 4 and the skeleton frame 5
is formed in a sealed state, and the air in the sealed air cushion chamber 6 has a cushioning effect.
Therefore, the seat frame 1 is formed taking into consideration the height of the entire seat, and the cushion material 7 is made thinner by the thickness of the sealed air cushion chamber 6. The outer surfaces of the cushion material 7 and the seat frame 1 are integrally surrounded by a skin 8.

A thermoplastic synthetic resin such as ionomer or nylon is extruded by an extruder into the space between the molds 2 and 3 by blow molding, expanded to a certain size while blowing air, cooled, and then taken out from the molds 2 and 3. A seat frame 1 is molded.

バネフレーム４全体が柔らかく上下して良好なク
ツシヨン性が得られる。 Therefore, since the left and right sides of the spring frame 4 are provided with hanging portions 9 that widen outward as they reach the lower end, and the front and rear sides of the spring frame 4 are also provided with hanging portions 11 that widen outward as they reach the lower end, the spring frame When a load is applied to 4, the upper ends of the hanging portions 9 and 11 both sink downward when they move inward, producing a cushioning effect.
The entire spring frame 4 moves up and down softly to provide good cushioning properties.

一層クツシヨン性を高め、かつ耐久性も高める。 Furthermore, the skeleton frame 5 is not a horizontal structure,
The left and right sides are formed with hanging parts 10 that widen outward as they reach the lower end, and the front and rear sides of the skeleton frame 5 are formed with hanging parts 12 that widen outward as they reach the lower end. to support the hanging part 9 and the hanging part 11,
Further improves cushioning properties and durability.

る。 In addition, the seat frame 1 includes a spring frame 4
and the skeleton frame 5, and since the sealed air cushion chamber 6 is formed in a sealed state, the sealed air cushion chamber 6 alone can produce a cushioning effect. , the cushion material 7 can be made thinner by the thickness of the sealed air cushion chamber 6.
