DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, with reference to the accompanying drawings, the illustrated embodiment the seat back B and the seat surface b _1, a c ₁ surface of the seat cushion C in a vehicle seat as shown in Figure 1 and forming at Jo elastic body, it is applied to provide a bank portion b _2, c ₂ as to surround the periphery of the seating surface b _1, c _1. This vehicle seat is assembled using a seat frame formed into a substantially quadrangular frame shape from each side portion that is axially bent into a predetermined axis shape so as to conform to a sitting posture of a human body.

[0013] As a sheet will be described with seat back B shown in FIG. 2, the bearing surface b ₁ are formed in the fabric surface elastic body 1 of stretchy. As the planar elastic body 1, for example, one formed of a plurality of elastomer monofilaments obtained by interweaving a plurality of strands of fibrous yarn used for an interior fabric or 1000 to 4000 denier elastomer monofilament is used for a warp or a weft. Thus, a woven or knitted fabric having elasticity can be used.

The seat back B is formed on a base frame of a metal pipe seat back frame 2 (hereinafter referred to as a "pipe frame"). As shown in FIG. 3, the bank b ₂ embeds and inserts the axis of the pipe frame 2 therein, and the planar elastic body 1 is joined and fixed at a terminal to stretch and support the planar elastic body 1 inward. a bank base 30 which is provided integrally on the axis of the seat frame 2 by a bank face 31 raised from the seat surface b ₁ is attached and fixed to the seat surface base 30.

The bank base 30 is formed of a synthetic resin such as polypropylene or polyethylene terephthalate, and the resin is molded along the axis of the pipe frame 2 by inserting the axis of the pipe frame 2 therein and performing injection molding. Further, the planar elastic body 1 is assembled into an injection molding die by clamping the terminal with a clamp or the like and tensioning and supporting the whole from the surroundings with an appropriate tension, and laying the terminal side on the surface side of the bank base 30 to lay the base side. Since the injection molding 30 is performed, it is joined and fixed to the inside of the bank base 30 so as to be stretched and fixed.

The bank surface portion 31 is a resin molded as a curved body of the three-dimensional shaped raised from the seat surface b ₁ has a stable well capable of supporting the raised degree from both sides of the human body upper body seated posture. The bank surface portion 31 is formed from a soft rubber-based resin material, and can be formed using, for example, a thermoplastic elastomer.

The bank surface portion 31 is blow-molded as a hollow elastic body, and a stopper 32 such as a clip is formed so as to protrude toward the back, so that the seat surface base 30 is used as a seat to press-fit the stopper 32. It can be stably mounted and fixed to the seat base 30. Instead of attaching and fixing the bank surface portion 31 with a stopper 32 such as a clip, the bank surface portion 31 is used.
May be formed integrally with the seat base 30 when blow-molding.

The bank surface portion 31 is hollow as well as
As shown in the above, those formed into a cross-sectional bay shape from an elastomeric material such as olefin or polyester can be used. The bank surface portion 31 having a bay-shaped cross section is formed of a hollow elastic body having an internal space by forming projecting flange portions 31a and 31b along both ends and welding and fixing the projecting flange portions 31a and 31b to the bank base 30. it can be joined and fixed to the bank base 30 as bank portion b _2.

[0019] In the seat back such a configuration, the time of sitting by the provision of the bank portion b ₂ for raised from the seat surface b ₁ have stable well capable of supporting the raised degree from both sides of the human body upper body seated posture Holdability can be improved. Further, the bank portion b ₂ is resin-molded integrally with bank base 30 stretched supporting the planar elastic body 1 inside the pipe frame 2 as the base frame, mounted fix the bank face 31 as seat receives the bank base 30 since formed by, it can be assembled into one robust the entire sheet including the bank portion b ₂ with a simple configuration.

[0020] In addition, by the bank portion b ₂ is provided with a bank face 31 of the hollow elastic body formed of a resin material of a soft rubber, a hold at the time of seating, of course, touch or the cushioning properties better seating It can be provided as having excellent properties.

The components described above can be applied to the seat cushion C shown in FIG. In the seat cushion C, a seat cushion frame formed by the pipe frame 2 is used as a base frame, and an axis of the pipe frame 2 is embedded therein, and a bank base 30 that stretches and supports the planar elastic body 1 inward is formed by resin molding. bank portion b by attaching and fixing the bank surface 31 raised from the seat surface b ₁ a waist from the thigh with a stable well capable of supporting the raised degree in sitting position by the planar elastic body 1 in the sitting base 30 ₂ can be provided.

[0022] Other embodiments described above, the bank portion b ₂ is provided with a vent hole 33 communicating with the bank base 30 from the bank surface portion 31 as shown in Figure 3, comprises an air valve (not shown) Can be provided as a hollow elastic body whose air pressure can be adjusted. In the bank portion b _2, air inside the structure to be placed naturally out from the vent hole 33 or to feel by equipping the electric air out put mechanism moderately adjustably as required cushioning Can be provided.

Also, as shown in FIG.
4 may be deposited on the curved surface of the bank surface portion 31 raised from the bearing surface b _1. The skin material 34 can be integrally formed by being inserted into a mold when the bank surface 31 is blow-molded or injection-molded. When provided with the skin material 34 can be improved together with the bank surface portion 31 formed of a resin material of a soft rubber, tactile and decorative the bank portion b _2.

[0024]

As described above, according to the seat having the seating surface of the sheet-like elastic body according to the first aspect of the present invention, the sheet-like elasticity has a degree of protrusion that can stably support the human body in a sitting posture. By providing a bank portion that protrudes from the seat surface of the body, it is possible to improve the holdability at the time of sitting. In addition, the bank base that stretches and supports the sheet elastic body inward with the seat frame as the base frame is integrally molded with resin, and the bank base is attached and fixed as the receiving base, so that the entire seat including the bank is used. It can be made robust with a simple configuration.

According to the seat having the seating surface of the planar elastic member according to the second aspect of the present invention, the provision of the bank portion of the hollow elastic member provides not only the holding property at the time of sitting, but also the tactile sensation or cushioning property. The seat can be configured as a good and excellent seating property.

According to the seat having a seat made of a sheet-like elastic material according to claim 3 of the present invention, since a bank-like surface portion made of a soft rubber-based resin material is provided and a bank-like portion of a hollow elastic body is provided, It is possible to construct a seat that is more excellent in the seating property as well as the touch feeling or the cushioning property of the bank portion as well as the holding property at the time of sitting.

According to the seat having a seat made of a sheet-like elastic body according to a fourth aspect of the present invention, a bank portion is provided in which a skin material such as cloth is attached to a curved surface of a bank surface portion protruding from the seat surface. This makes it possible to provide a sheet having a better tactile sensation and excellent decorativeness.

According to the seat having the seating surface of the planar elastic body according to the fifth aspect of the present invention, by providing a bank portion whose air pressure can be adjusted by the ventilation hole, the feel or cushioning property of the bank portion is improved. It can be configured as a sheet that can be kept moderately as needed.
