The planar heating element 30 includes a first heating element 31 arranged behind the handle opening 13 and a second heating element 32 arranged below the handle opening 13 and the first heating element 31. Further, a third heating element 33 may be provided on the upper surface of the armrest 11.

The first heating element 31 to the third heating element 33 of the planar heating element 30 are provided with a heating element 40 containing carbon nanotubes and a pair of electrodes 41 and 42, respectively.
Carbon nanotubes are one of the carbon nanomaterials, and are composed only of carbon and are nanometer-sized cylindrical (tube) -shaped substances. Examples of carbon nanomaterials include carbon nanoballs, carbon nanobags, and the like, in addition to carbon nanotubes. Hereinafter, carbon nanomaterials containing carbon nanotubes will be described as examples.
The carbon nanotube itself has extremely high conductivity, thermal conductivity, and heat resistance, and by including it as a conductive member in a heating element, it is possible to generate more radiant heat than conduction heat.

Further, as shown in FIG. 1, among the planar heating elements 30, the first heating element 31 and the second heating element 32 are connected in parallel by a conductive wire 43. Further, the first heating element 31 is connected to an ECU (not shown) provided in the vehicle by a conductive wire 43, and the heating elements of the first heating element 31 and the second heating element 32 can be adjusted by the ECU. It has become.

As described above, compared with the case where a plurality of heating elements (first heating element 31 and second heating element 32) are connected in parallel by a conductive wire 43 and a plurality of heating elements are connected in series (see FIG. 2). Therefore, the first electrode 41 and the second electrode 42 can be miniaturized. Further, since the number of portions used for connecting the first electrode 41 and the second electrode 42 and the planar heating element 30 is reduced, the heat generation area can be further increased.

Further, in FIG. 1, when the occupant H is seated on the vehicle seat S1 as shown by the dotted line, the first heating element 31 and the second heating element 32 are arranged at positions facing the occupant H. By arranging the first heating element 31 and the second heating element 32 at a position close to the occupant H, the body of the occupant H can be efficiently warmed. Further, since the first heating element 31 and the second heating element 32 face the occupant H, the first heating element 31 and the second heating element 32 containing the carbon nanomaterial can efficiently radiate radiant heat. It is possible to efficiently warm the body of the occupant H without directly touching the heating element as in the conventional case. In addition, the power consumption can be suppressed as compared with the hot air device that sends hot air.

As shown in FIG. 1, the vehicle door lining 1 of the present embodiment is provided with an armrest 11 that protrudes from the door lining main body 10 toward the vehicle interior side and on which the arm of the occupant H can be placed.
Since the first heating element 31 and the second heating element 32 are arranged above the armrest 11 of the vehicle door lining 1, the upper body of the occupant H can be efficiently warmed.
Further, as shown in FIG. 1, the door lining main body 10 of the present embodiment is formed with a handle opening 13 for inserting the door handle portion 12 which is supposed to be operated by the fingers of the occupant H.

It is placed at a position substantially opposite to. By arranging the second electrode 42 at a position facing the seat back 21, most of the heat generating portions 40 of the first heating element 31 to the third heating element 33 do not heat the side portion of the seat back 21. The heat generating portion 40 is arranged only at a necessary portion (position facing the upper body of the occupant H). That is, it is possible to efficiently warm the seated occupant H while suppressing the power consumption.

Further, as shown in FIG. 1, the planar heating element 30 is arranged below the lower end of the headrest 22 of the vehicle seat S1.
By arranging the planar heating element 30 below the lower end of the headrest 22, it is possible to suppress radiant heat from being radiated to the face of the seated occupant H. In particular, considering that the heating element 30 is used in the cold season, the upper body and arms of the occupant H are covered with clothes, but the occupant's head, mainly the face, is covered with clothes. It is not always covered. Therefore, radiant heat is directly radiated to the occupant's head. By arranging the planar heating element 30 below the lower end of the headrest 22, the amount of radiant heat radiated to the face part of the occupant H is reduced as compared with the case of warming other parts of the body of the occupant H. Can be done.

Therefore, the boss portion 513 is difficult to come out of the through hole 517.

FIG. 43C shows a protrusion 515a, which is another example of the protrusion 515. The protrusion 515a also has an inclined portion 523 on the root side. By providing the inclined portion 523 also in the portion on the root side, for example, the tongue-shaped portion 518 is obliquely in contact with the protruding portion 515, so that the positional deviation between the boss portion 513 and the through hole 517 can be absorbed.

44A-44C show the assembled seat 5016a-5016c, which is another example of the assembled seat 516. The assembled seat portion 5016a-5016c is different in size or position from the tongue-shaped portion 518 as compared with the assembled seat portion 516 shown in FIG. 42.

The tongue-shaped portion 518a of the assembly seat portion 516a shown in FIG. 44A is configured such that the width D2 thereof is narrower than the width W of the through hole 517a. Further, the tongue-shaped portion 518a is arranged at a position close to the main body side of the pocket member 512. In other words, the slit 5019a is formed so as to extend toward the pocket member 512.
With such a configuration, for example, the tongue-shaped portion 518a becomes difficult to see in appearance, and the design after welding is improved.

In the assembly seat portion 516b shown in FIG. 44B, the tongue-shaped portion 518b is arranged at a position away from the main body of the pocket member 512. This makes it possible to visually confirm the state in which the tongue-shaped portion 518b is engaged with the protrusion 515.

Further, the assembly seat portion 516c shown in FIG. 44C is provided with two tongue-shaped portions 518c, which are arranged so as to be located on opposite sides of each other. Although not shown, two protrusions 515 are also provided on the side of the boss portion 513, and are arranged so as to be located on opposite sides of each other. After inserting the boss portion 513, the two protrusions 515 are locked to the corresponding tongue-shaped portions 518c.
This makes it possible to more firmly fix the assembled seat portion 516c to the boss portion 513 during temporary assembly.

As described above, the assembly structure between the resin members according to the fifth embodiment has been described with reference to the drawings. In the embodiment, the reclining cover 510 has been described as a specific example, but the reclining cover 510 can be used for attachment between resin members for vehicles without particular limitation. For example, as shown in FIG. 45, this assembly structure may be used for attaching the pocket member 512a provided on the door lining 530 (door trim).
