  The operation unit 11 is disposed on the back side of the seat 10, and the operation unit 13 for realizing the same function as the operation unit 11 is disposed on the front side of the seat 10. Therefore, the user may perform a slide operation using the operation unit 11 or 13 which is easier to use. The operation unit 12 is disposed on the opposite side of the operation unit 11 from the operation unit 14 for realizing the same function as the operation unit 12. Therefore, the user may perform the reclining operation using the operation unit 12 or 14 which is easier to use.

  Marks are attached to the exposed surfaces of the operation units 11 and 12 (specifically, positions where the user can see the operation units 11 and 12 in the state in which the operation units 11 and 12 are accommodated in the accommodation recesses 161 and 162, respectively). These marks are used so that the user can easily distinguish which of the operation units 11 and 12 is a slide operation lever or a reclining operation lever.

  FIG. 3 is a perspective view of the operation units 11 and 12 according to the embodiment when the operation units 11 and 12 are not operated. FIG. 4 is a perspective view of a state during operation of the operation units 11 and 12 according to the embodiment. An attachment frame portion 16 is provided on the back side of the seat 10 (the rear side surface of the seat back 102), and the operation portions 11 and 12 are in a non-operating state (not operated by the user). The housing 16 is accommodated. The mounting frame portion 16 is provided with receiving recesses 161 and 162, and the operating portions 11 and 12 are received in the receiving recesses 161 and 162, respectively, when not operated.

FIG. 7A is a front view of the attachment frame portion 16 to which the operation portion 11 and the operation portion 12 are attached, and the case member 30 provided on the attachment frame portion 16. FIG. 7B is a cross-sectional view of the case member 30 taken along the line bb in FIG. FIG. 7C is a cross-sectional view of the case member 30 taken along the line cc of FIG.

  When viewed from the front side, the mounting frame portion 16 has four corners rounded, but has a substantially rectangular or rectangular outer shape, and is provided with an opening (not shown) provided on the surface side of the case member 30. Are provided so as to be fitted. As shown in FIG. 7A, the case member 30 has four corners rounded when viewed from the front side, but has a substantially rectangular or rectangular outer shape. The case member 30 is formed of a resin material such as plastic. In FIG. 7A, the case member 30 has a first side 30s1 provided on the lower side, a second side 30s2 provided on the upper side facing the first side 30s1, and a first side 30s1 and the first side 30s1. Between the two sides 30s2, it has a third side 30s3 provided on the left side and a fourth side 30s4 provided on the right side opposite to the third side 30s3. That is, the area on the surface side of the case member 30 is made larger than the area of the attachment frame portion 16. Accordingly, the first side 30 s 1, the second side 30 s 2, the third side 30 s 3, and the fourth side 30 s 4 of the case member 30 are provided outside the attachment frame portion 16. The first side 30s1, the second side 30s2, the third side 30s3, and the fourth side 30s4 of the case member 30 can also be regarded as corresponding to corner portions 30d of the case member 30 in FIG.

  In the following description, the case member 30 is described as being substantially rectangular, but the case member 30 can also be regarded as a cube having six surfaces. In this case, the attachment side surface of the attachment frame 16 of the case member 30 is the front surface, the opposite surface is the back surface, the first side 30s1 is the first side surface, the second side 30s2 is the second side surface, In other words, the three sides 30s3 can be referred to as a third side surface, and the fourth sides 30s4 can be referred to as a fourth side surface.

  The case member 30 is further provided with a first protrusion 30b serving as a first projecting portion on a right side portion corresponding to the fourth side 30s4, and on an upper side portion corresponding to the second side 30s2. A second protrusion 30c is provided as a second overhanging portion. As shown in FIG. 7B, the first protrusion 30b is provided on the side of the mounting frame 16 that faces the mounting surface, and the support surface 30bS of the first protrusion 30b is the mounting frame. 16 are provided on the mounting surface side. Similarly, as shown in FIG. 7C, the second projecting portion 30c is provided on the side facing the mounting surface of the mounting frame portion 16, and the supporting surface 30cS of the projecting portion 30c is the mounting frame portion. 16 are provided on the mounting surface side. In this example, the first protrusion 30b and the second protrusion 30c are connected along the second side 30s2 and the fourth side 30s4 to form one protrusion. The support surfaces 30bS and 30cS also constitute a connected support surface.

  The first protrusion 30b and the second protrusion 30c are provided to prevent deformation of a soft cushion material such as urethane. That is, the cushion material hits the support surface 30bS provided on the first protrusion 30b and the support surface 30cS provided on the second protrusion 30c, and deformation of the cushion material is prevented. Each of the first protrusion 30b and the support surface 30bS, and the second protrusion 30c and the support surface 30cS can be regarded as a deformation preventing portion of the cushion material.

  In FIG. 7, no protrusions (deformation preventing portions) are provided on the first side 30 s 1 and the third side 30 s 3. However, a projection (deformation prevention unit) having a configuration similar to that of the first projection 30b (second projection 30c) may be provided at the first side 30s1 and the third side 30s3. That is, in the case member 30, it is possible to provide a protrusion (deformation preventing portion) at a side portion where the cushion material may be deformed.

  FIG. 8 is a diagram illustrating the relationship between the protrusion of the case member and the cushion material according to the embodiment. On the surface side of the case member 30, that is, on the attachment surface side of the attachment frame portion 16, a seat skin 50 is provided on the back side of the sheet 10 except for the attachment portion of the attachment frame portion 16. Mounting is performed such that a portion 40b (40c) of a soft cushioning material 40 such as urethane is inserted between the first protrusion 30b (second protrusion 30c) and the seat skin 50 on the back side of the seat 10. It is done. That is, the cushion member 40 has a recess or a notch that fits between the support surface 30bS (30cS) of the first protrusion 30b (second protrusion 30c) and the soft sheet skin (skin material) 50. 41 or a protrusion 40b (40c) is provided.

  According to this configuration, since the first protrusion 30b and the second protrusion 30c are provided, the protrusion 40b or 40c of the cushion material 40 is provided on the support surfaces 30bS and 30cS of the first protrusion 30b and the second protrusion 30c. Supported, deformation is prevented. That is, for example, even when the portion 50b (50c) of the soft seat skin 50 that is in contact with the cushion material 40 is pressed by the occupant's hand, elbow, knee, or the like, a portion (end portion) 40b of the cushion material 40 or Since 40c is supported by the support surfaces 30bS and 30cS of the first protrusion 30b and the second protrusion 30c, deformation of the end portion (40b or 40c) of the cushion material 40 is prevented. For this reason, it is possible to prevent the outer shape of the corner portion 30d of the case member 30 from appearing on the sheet skin 50, so that the appearance quality of the sheet skin 50 can be stabilized and improved.

  FIG. 9 is a diagram illustrating the relationship between the case member and the cushion material according to the comparative example. A sheet skin 50 is provided on the back side of the sheet 10 on the surface side of the case member 30, that is, on the attachment surface side of the attachment frame portion 16. In FIG. 9, the case member 30 is not provided with the first protrusion 30b (or the second protrusion 30c) as shown in FIG. Therefore, when the portion 50b (50c) of the seat skin 50 on the back surface side of the seat 10 that is in contact with the cushion material 40 is pressed by the occupant, the cushion material 40 is deformed, and the outer shape of the corner 30d of the case member 30 is the seat skin 50. Appear in Therefore, it becomes extremely difficult to stabilize and improve the appearance quality of the sheet skin 50.

  FIG. 10 is a front view of the rear side of the seat back when the seat skin is removed. FIG. 11 is a front view of the rear side of the seat back when the cushion material of FIG. 10 is removed. As shown in FIG. 10, on the rear side of the seat back 102, almost the entire surface except for the surface side of the seat belt protection member (protective cover) 200 a and the case member 30, that is, the attachment surface side of the attachment frame portion 16 40. The sheet skin is provided so as to cover the sheet 10 so that the attachment frame portion 16 and the operation portions 11 and 12 are exposed. As shown in FIG. 11, the protrusions 30b and 30c of the case member 30 are provided as described with reference to FIG. The attachment frame portion 16 and the case member 30 are fixed to a seat back frame of the seat back 102 or a pipe or the like constituting the seat back frame.

  As can be understood by comparing FIG. 10 and FIG. 11, the cushion material 40 is provided so as to cover the protrusions 30b and 30c of the case member 30, and as described in FIG. The support surfaces (30bS, 30cS) of 30b, 30c can support the end portion of the cushion material 40. Thereby, a deformation | transformation of the edge part (40b or 40c) of the cushion material 40 is prevented. In this example, since the seat belt protective member (protective cover) 200a is provided, the cushion member 40 is not provided on the left side portion (third side 30s3) of the case member 30. Therefore, no protrusion is provided on the left side portion (third side 30 s 3) of the case member 30.

  For example, when the seat belt protection member (protective cover) 200a is not provided on the left side portion of the case member 30 and the cushion member 40 is provided on the left side portion of the case member 30, the left side portion (third side 30s3) of the case member 30 is provided. It is preferable to provide a protrusion on the surface.

  2, since the pocket 104 is provided in the lower part (first side 30s1) of the case member 30, a protrusion is formed on the lower part (first side 30s1) of the case member 30. No part is provided.

  For example, when the pocket 104 is not provided in the lower part of the case member 30, it is preferable to provide a protrusion on the lower part (first side 30s1) of the case member 30.

  As mentioned above, the invention made by the present inventor has been specifically described based on the examples. However, the present invention is not limited to the above-described embodiments and examples, and needless to say, various modifications can be made. .
