  The side support portion 31 of the side support member 30 is disposed below the first groove C31 so as to straddle the corresponding first groove C31 in the left-right direction. That is, the side support portion 31 and the first groove C31 are arranged to intersect. Further, the side support portion 31 is disposed at a position between the second groove C32 and the third groove C33 in the front-rear direction.

Next, the function and effect of the vehicle seat S configured as described above will be described.
As shown in FIG. 6, when a person (seated person P) sits on the vehicle seat S, the side support portions 31 of the left and right side support members 30 arranged to sandwich the hip point HP on both the left and right sides of the hip point HP. The sides of the buttocks and the thighs of the seat occupant P can be supported from the left and right sides by the above. Thereby, compared with the case where the side support part 31 is not arrange | positioned, the side of the buttocks and thighs of the seated person P can be firmly supported. As a result, the pressure around the ischium P1 (more precisely, where it protrudes to the bottom of the ischium P1; the same applies hereinafter) is relatively lowered, so the seater in the area around the ischium P1 and the entire hip and thigh P can be supported in a well-balanced manner. As a result, blood circulation around the ischium P1 of the seated person P is less likely to deteriorate, so that the seated person P's feeling of fatigue can be reduced even when sitting for a long time.

  Further, since the side support member 30 is provided on the cover member 80, by attaching the cover member 80 to the side frame 11, both the cover member 80 and the side support member 30 can be attached to the cushion frame F1. As a result, it is not necessary to arrange the side support member at the mounting position separately from the cover member or to fix the side support member with a screw, so that the number of steps for mounting the member on the cushion frame F1 can be reduced.

  In addition, since the first support surface 31A of the side support member 30 is an inclined surface positioned upward as it goes to the left and right outside, the human body (seated person P by the support wire 20 and the first support surface 31A on the left and right) A concave shape can be formed along the shape of. Thus, when the seated person P sits on the vehicle seat S, the seated person P can be stably supported, and a comfortable sitting comfort can be realized.

  Further, since the side support member 30 is integrally formed with the cover member 80, as compared with the case where the side support member and the cover member are formed as separate components in the process before the members are attached to the cushion frame F1. The number of man-hours in manufacturing the vehicle seat S can be reduced.

  Further, in the configuration in which the cover member 80 and the side support member 30 are integrally formed, the inner cover portion 81 and the side support portion 31 are separated by the slit 81A. As compared with the case where the side supporting portion 31 is bent, the side supporting portion 31 is easily bent. As a result, when the seated person P sits on the vehicle seat S, it is possible to provide an appropriate cushioning property, so that a comfortable sitting comfort can be realized.

  Further, since the width of the side support portion 31 in the front-rear direction is 10 cm or more, the load can be supported by the side support portion 31 having a large width. Thus, when the seated person P sits on the vehicle seat S, the seated person P can be stably supported, and a comfortable sitting comfort can be realized.

  Moreover, since the width in the front-rear direction of the side support portion 31 is larger toward the left and right inside, the front-rear width of the left and right outer sides of the side support portion 31 becomes relatively smaller, Since it becomes possible to bend, appropriate cushioning can be provided. Moreover, since the front-rear width inside the right and left of the side support part 31 becomes relatively large, since a load can be supported by the part with large width | variety, the seating person P can be supported stably. As a result, when the seated person P sits on the vehicle seat S, a more comfortable sitting comfort can be realized. By setting the front-rear width of the upper end having the smallest front-rear width of the side support portion 31 to be 10 cm or more, the strength of the side support portion 31 near the upper end to which a large load is applied can be improved.

  As mentioned above, although one embodiment of the invention was described, the present invention is not limited to the above-mentioned embodiment. About a specific structure, it can change suitably in the range which does not deviate from the meaning of invention as follows. In the following, the same components as those described above are denoted by the same reference numerals, and the description thereof will be omitted as appropriate, and points different from the components described above will be described in detail.

  For example, as shown in FIG. 7, the side support portion 31 may have a through hole 31H. In the embodiment shown in FIG. 7, the through hole 31 H has, for example, a substantially trapezoidal shape long in the front-rear direction, and is formed in the lower portion of the side support portion 31. Since the side support member 31 can reduce the weight of the side support member 30 by having the through holes 31H, the weight reduction of the vehicle seat S including the side support member 30 can be achieved. Moreover, since it becomes possible to arrange other members, such as a wire harness and a duct for air conditioning, through the through holes 31H, a limited space in the vehicle seat S can be effectively utilized. The shape and number of the through holes, the position to be provided, and the like are not particularly limited, and can be set as appropriate.

  Further, as shown in FIGS. 8A and 8B, the end portion of the side support member 30 at the inner side in the left-right direction may be connected to the second support wire 22. For example, in the configuration shown in FIG. 8A, the side support member 30 is configured such that the second inward end of the extension 35 covers the entire circumference of a part of the second support wire 22. The second support wire 22 is connected to the second support wire 22 by being provided so as to wrap a part of the support wire 22. In other words, the second support wire 22 is disposed to pass through the left and right inner end portions of the extending portion 35. Such a configuration in which the second metal support wire 22 and the resin side support member 30 are integrally formed is formed, for example, by insert molding the second support wire 22 and the side support member 30. can do.

Further, in the embodiment shown in FIG. 8B, the side support member 30 has a hook-like engaging portion 35A at the end on the inner side in the left-right direction of the extending portion 35, and this engaging portion 35A is the second one. By engaging a portion of the support wire 22, it is connected to the second support wire 22.
Thus, by the side support member 30 being connected to the second support wire 22, the side support member 30 can prevent the second support wire 22 from sinking too much downward. As a result, when the seated person sits on the vehicle seat S, a comfortable sitting comfort can be realized. In addition, the side support member 30 on either side may be connected with both the 2nd support wire 22 and the 1st support wire 21, for example by being integrally formed with the wire connection member 50 (refer FIG. 2). . Furthermore, the left and right side support members 30 may be connected integrally by the wire connection member 50.

  Moreover, in the said embodiment, although the side support member 30 was integrally formed with the cover member 80, it is not limited to this. For example, as shown in FIG. 9, the side support member 30 may be formed as a component separate from the cover member 80. In the embodiment shown in FIG. 9, as an example, the side support member 30 is provided on the cover member 80 by fixing the upper end portion of the side support portion 31 to the cover member 80 by means of a mounting member 91 such as a screw or a rivet. There is.

  Moreover, in the said embodiment, although the cover member 80 had the inner cover part 81, the upper cover part 82, and the rear cover part 83, it is not limited to this.
