In the figure, reference numeral 1 denotes a frame-shaped frame disposed within the seat bag of an automobile seat. A support wire 2 is stretched in the frame 1, and elastic members 3a and 3 made of fabric support the lumbar region of the occupant and the upper part thereof.
b is erected with hooks 4, 4... The upper and lower parts of the support wire 2 are formed to have the same width, and elastic members 3a and 3b are stretched over the upper and lower parts, respectively, and the lower part 3a and the upper part 3b have different basis weights. That is, the lower elastic member 3a is formed to have a larger basis weight than the upper elastic member 3b, and has greater elasticity than the upper elastic member 3b. That is, this seat bag is formed to have greater elasticity on the lumbar vertebrae side where elasticity is required than on the upper side.

る。(Means for Solving the Problems) Therefore, in the support structure of the vehicle seat of the present invention, the elastic member is formed such that a portion of the elastic member is narrower in the left-right direction than the other portion. The width of the support wire is uniform throughout, and the narrow portion is used for areas where elasticity is required in the elastic member, such as the lumbar support portion and the seat cushion in the case of a seat bag. In this case, this is the part corresponding to the thigh support part.
従つて、幅が全体に均一であるサポートワイヤ

した弾性部材の弾力は他部分に対して大になる。 Therefore, if a fabric elastic member having a narrow portion is stretched over a support wire whose width is uniform throughout, the elasticity of the elastic member stretched over the narrow portion will be lower than that of other parts. becomes large against
（実施例）
以下、本考案の一実施例を第１図乃至第６図に
基づいて説明する。(Example) Hereinafter, an example of the present invention will be described based on FIGS. 1 to 6.
同図中において第７図と同一符号は同一部材を

シートバツクＡが形成される。 In the figure, the same symbols as in FIG. 7 indicate the same members. What is shown is a support structure B attached to a seat back A of an automobile seat (Fig. 3).
(FIG. 1), this support structure B consists of a frame 1 made of pipe, a support wire 2 and an elastic member 3 made of cloth, and hooks 4, 4 installed therein.
When a foam cushion material (not shown) is attached to this support structure B to cover the skin member 10,
Seat bag A is formed.

ム１に取付けられる。 As shown in FIG. 4, the entire support wire, that is, the width of the upper part 21 corresponding to the upper body of the seated person and the lower part 22 corresponding to the lumbar support part is formed to have the same width, and in this state, it cannot be deformed. It can be attached to frame 1 without needing to be attached.

弾性が要求される部分３１の幅が他の部分３２に
対して幅狭状に形成され、その左右方向の両側は
内側に折り返されて袋状に形成され内部にサポー
トワイヤ２を挿通できるように形成されている。 The elastic member 3 attached to the support wire 2 is formed so that a portion 31 where elasticity is required is narrower than other portions 32, and both sides of the elastic member 3 in the left and right direction are folded inward to form a bag shape. It is formed so that the support wire 2 can be inserted thereinto.
以上の弾性部材３はその全体が同一の弾性を有
する織物で、前記弾性が要求される部分３１はサ
ポートワイヤ２の下部２２に、また他の部分が上
部２１に夫々張設される。 The elastic member 3 described above is made of a fabric having the same elasticity as a whole, and the part 31 that requires elasticity is stretched over the lower part 22 of the support wire 2, and the other parts are stretched over the upper part 21, respectively.
この弾性部材３の一例を示すと、張設方向に伸

らないように形成したものである。 An example of the elastic member 3 is a woven fabric that stretches in the direction in which it is stretched, and is plain woven with polyester twisted yarns in the warp and elastic monofilaments of polyester or elastomer in the weft. The intersection with the warp is heat-sealed to prevent the weft and warp from slipping.

が大になる。 When this elastic member 3 is stretched around the support wire 2, the elastic member 3 is stretched as shown in FIG.
The narrow-width portion 31 that requires elasticity and the other portion 32 are stretched to have the same width. That is, since the portion 31 of the elastic member 32 that requires elasticity is wider in the left-right direction than the other portions 32, the elasticity is greater.
なお、前記弾性部材３の形状は任意で、例えば
第６図に示すように形成しても良い。 Note that the shape of the elastic member 3 is arbitrary, and may be formed as shown in FIG. 6, for example.

る。 Furthermore, although the above embodiments have been described with respect to seat bags, it is clear that the present invention can also be applied to seat cushions. That is, this can be obtained by forming the width of the cloth-like elastic member in the portion corresponding to the thigh support portion of the seat cushion to be narrower than in other portions, and then stretching the cloth-like elastic member around the support wire in the same manner as described above.
（効果）

を図ることができる。(Effects) According to the present invention, the elasticity of a single elastic member can be changed by simply changing the width of a portion of the cloth-like elastic member. Therefore, unlike conventional products, there is no need to use a large number of elastic members with different elasticities, which simplifies manufacturing and management and reduces costs.
さらに、一枚の弾性部材をサポートワイヤに取
付ければよいので、その取付作業が容易化する。 Furthermore, since it is only necessary to attach one elastic member to the support wire, the attachment work is facilitated.
