As shown in FIG. 2, side support members 30 are arranged on both left and right sides of the support wire 20. The left and right side support members 30 are members that support the cushion pad C1 (see FIG. 3) together with the support wire 20, the rear support member 70, and the like, and are made of resin. Each side support member 30 is provided on the corresponding left and right cover members 80. In this embodiment, the side support member 30 is integrally formed with the cover member 80 as a part of the cover member 80 by integral molding of resin. Specifically, the side support member 30 is formed to extend inward in the left-right direction from the inner end in the left-right direction of the front end portion of the upper cover portion 82 .

As shown in FIG. 5, the left and right side support members 30 are arranged one each on the left and right of the hip point HP of the seated person. Each side support member 30 is arranged in a range including the hip point HP in the front-rear direction. In other words, the side support members 30 are arranged on both left and right sides of the hip point HP so as to sandwich the hip point HP when viewed from above and below. Note that in this specification, the hip point HP is the position of the hip point when a 3D mannequin based on SAE J-826 is seated on a seat. As shown in FIG. 2, each side support member 30 has a side support part 31 as an example of a support part and an extension part 35.

The side support portion 31 is a plate-shaped portion located inside the side frame 11 in the left-right direction, and is provided adjacent to the front side of the inner cover portion 81. In other words, in this embodiment, the cover member 80 with which the side support member 30 is integrally formed has a slit 81A between the inner cover part 81 and the side support part 31, and this slit 81A allows the side support member 30 to be formed integrally with the side support member 30. 11 is separated into an inner cover part 81 and a side support part 31. The slit 81A extends outward in the left-right direction from the inner edge in the left-right direction of the portion of the cover member 80 located on the left-right inner side of the side frame 11, specifically, extends upward from the lower edge 81B of the inner cover portion 81. It is shaped like a notch.

The side support portions 31 are arranged in an inclined state such that the further outward in the left-right direction, the higher the side support portions 31 are. In other words, the side support portion 31 extends diagonally downward from the inner end in the left-right direction of the front end portion of the upper cover portion 82 toward the inner side in the left-right direction. Each side support portion 31 has a substantially trapezoidal shape in which the width in the front-rear direction increases toward the inner side in the left-right direction (see also FIG. 5). As an example, it is desirable that the width of the side support portion 31 in the front-rear direction is 10 cm or more. Specifically, it is desirable that the side support portion 31 has a width of 10 cm or more at the upper end where the width in the front-rear direction is the smallest.

Each side support portion 31 has a first support surface 31A that is an upper surface. The first support surface 31A is an example of a support surface. In the present embodiment, the first support surface 31A is arranged such that the plate-shaped side support portion 31 is positioned upwardly as it goes outward in the left-right direction. It is a sloped surface.

The extending portion 35 is provided so as to extend inward in the left-right direction from the lower end of the side support portion 31 . Each extending portion 35 is arranged to rest on the corresponding second support wire 22 on the left and right.

As shown in FIG. 5, the cushion pad C1 has a center portion C10 and left and right side portions C20 provided on both left and right sides of the center portion C10 and projecting above the center portion C10. Moreover, the cushion pad C1 has a suspension groove C30 for suspending the skin material U1 (see FIG. 3).

The hanging groove C30 includes left and right first grooves C31 extending in the front-rear direction, and a second groove C32 and a third groove C33 extending in the left-right direction.
The left and right first grooves C31 are formed to extend along the boundary between the center portion C10 and each side portion C20 on both left and right sides of the hip point HP.
The second groove C32 is formed on the front side of the hip point HP so as to connect the left and right first grooves C31 near the center in the front-rear direction.
The third groove C33 is formed on the rear side of the hip point HP so as to connect the rear portions of the left and right first grooves C31.

Further, a suspension wire (not shown) for suspending the skin material U1 into the suspension groove C30 is embedded in the cushion pad C1 by insert molding. The suspension wire is arranged along the suspension groove C30, and is partially exposed through a plurality of holes C50 formed at the bottom of the suspension groove C30. The skin material U1 is fastened to the cushion pad C1 by engaging a hook (not shown) provided on the skin material U1 with a portion exposed from the hole C50 of the hanging wire.

The side support portions 31 of the side support members 30 are arranged below the first grooves C31 so as to straddle the corresponding first grooves C31 in the left-right direction. That is, the side support portion 31 and the first groove C31 are arranged to intersect with each other. Moreover, the side support part 31 is arranged at a position between the second groove C32 and the third groove C33 in the front-rear direction.

Next, the effects of the vehicle seat S configured as described above will be explained.
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 are arranged on both the left and right sides of the hip point HP so as to sandwich the hip point HP. By this means, it is possible to support the seated person P's buttocks and thighs so as to sandwich them from the left and right sides. As a result, the sides of the buttocks and thighs of the seated person P can be supported more firmly than in the case where the side support portions 31 are not provided. As a result, the pressure around the ischial bone P1 (more precisely, the lowest protruding part of the ischial bone P1; the same applies hereinafter) is relatively reduced, so the pressure around the ischial bone P1 and the entire buttocks and thighs of the seated person P can be supported in a well-balanced manner. This makes it difficult for the blood circulation around the sitting bone P1 of the seated person P to deteriorate, so that the feeling of fatigue in the seated person P can be reduced even if the seated person P sits 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. Thereby, there is no need to arrange the side support member at the mounting position separately from the cover member or to fix the side support member with screws, so the number of steps when attaching the member to 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 located upward as it goes to the left and right sides, the support wire 20 and the left and right first support surfaces 31A are connected to the human body (the seated person) when viewed from the front and rear directions. ) can be formed into a concave shape. Thereby, when the seated person P sits on the vehicle seat S, it is possible to stably support the seated person P, thereby realizing a comfortable sitting feeling.

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

Moreover, since the cover member 80 and the side support member 30 are integrally formed, and the inner cover part 81 and the side support part 31 are separated by the slit 81A, the inner cover part and the side support part are connected at the front and back. The side support portions 31 are more easily bent than in the case where the side support portions 31 are bent. Thereby, when the seated person P sits on the vehicle seat S, it is possible to provide appropriate cushioning properties, so that comfortable sitting comfort can be achieved.

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. Thereby, when the seated person P sits on the vehicle seat S, it is possible to stably support the seated person P, thereby realizing a comfortable sitting feeling.

In addition, since the width of the side support part 31 in the front-rear direction increases as it goes toward the left and right inner sides, the front-rear width of the left and right outer sides of the side support part 31 becomes relatively small, and the side support part 31 can be moved up and down appropriately. Since it is possible to flex, it is possible to provide appropriate cushioning properties. Further, since the front and rear widths of the side support portions 31 on the left and right inner sides are relatively large, the load can be supported by the large width portions, so that the seated person P can be stably supported. Thereby, when the seated person P sits on the vehicle seat S, it is possible to realize more comfortable sitting comfort. In addition, by setting the front-back width of the upper end of the side support part 31 where the front-back width is the smallest to 10 cm or more, the strength of the side support part 31 near the upper end, which is subjected to a large load when bending, can be improved.

Although one embodiment of the invention has been described above, the invention is not limited to the above embodiment. The specific configuration can be modified as appropriate without departing from the spirit of the invention, as described below. In addition, below, the same code|symbol is attached|subjected about the structure similar to the structure demonstrated previously, and description is abbreviate|omitted suitably, and the point different from the structure explained previously is demonstrated in detail.

For example, as shown in FIG. 7, the side support portion 31 may have a through hole 31H. In the form shown in FIG. 7, the through hole 31H has, for example, a substantially trapezoidal shape that is 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 has the through hole 31H, the weight of the side support member 30 can be reduced, so that the vehicle seat S including the side support member 30 can be reduced in weight. Further, other members such as a wire harness and an air conditioning duct can be placed through the through hole 31H, so the limited space within the vehicle seat S can be effectively utilized. Note that the shape, number, and position of the through holes are not particularly limited and can be set as appropriate.

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

Further, in the form shown in FIG. 8(b), the side support member 30 has a hook-shaped engagement portion 35A at the inner end in the left-right direction of the extension portion 35, and this engagement portion 35A is the second engagement portion 35A. It is connected to the second support wire 22 by engaging with a part of the support wire 22 .
By connecting the side support member 30 to the second support wire 22 in this manner, it is possible to prevent the second support wire 22 from sinking too far downward by the side support member 30. Thereby, when the seated person sits on the vehicle seat S, it is possible to realize a comfortable sitting feeling. Note that the left and right side support members 30 may be connected to both the second support wire 22 and the first support wire 21 by being formed integrally with the wire connection member 50 (see FIG. 2), for example. . Furthermore, the left and right side support members 30 may be connected by a wire connection member 50 and formed integrally.

Further, in the embodiment, the side support member 30 is formed integrally with the cover member 80, but the present invention is not limited thereto. For example, as shown in FIG. 9, the side support member 30 may be formed as a separate component from the cover member 80. In the form 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 with a mounting member 91 such as a screw or a rivet. There is.
