3. Features of Armrest According to this Embodiment In the armrest 10 according to this embodiment, a wire harness 14 is routed between the first box portion 15A and the cushioning material 13 (see FIG. 6).

  Thereby, in the armrest 10 which concerns on this embodiment, compared with the armrest (refer FIG. 11) in which the hook-shaped groove part for routing the wire harness 14 was provided, for example, the enlargement of 11 A of 1st storage space is carried out. It becomes possible.

  That is, if the armrest shown in FIG. 11 (hereinafter referred to as a grooved armrest) and the armrest 10 according to the present embodiment have the same size, the grooved armrest is provided with the groove portion described above. The first storage space 11A of the attached armrest must be smaller than the first storage space 11A according to the present embodiment.

  In other words, the groove portion requires a space for housing the wire harness 14 and a wall-shaped member constituting the space. For this reason, the space which the said groove part occupies becomes larger than the space for accommodating the wire harness 14.

  On the other hand, since the wire harness 14 according to the present embodiment is routed between the first box portion 15A and the cushioning material 13, the space necessary for routing the wire harness 14 is as described above. It is smaller than the space occupied by the groove (see FIG. 6). Therefore, in the armrest 10 according to the present embodiment, it is possible to increase the size of the first storage space 11A while suppressing the increase in size.

  The wire harness 14 is routed on one end side in the width direction of the first box portion 15A so as to extend from the swing center axis Lo side to the distal end side of the first box portion 15A. As a result, the size of the first storage space 11A in the width direction can be increased.

  Since the wire harness 14 is routed on one end side in the width direction of the armrest box 15, when the armrest 10 is in the storage position and the lower surface side of the armrest box 15 constitutes a part of the seat back 5, the center seat There is no sense of incongruity for seat occupants.

  That is, if the wire harness 14 is routed between the lower surface of the armrest box 15 and the cushioning material 13, the back of the seated person is supported by the wire harness 14 when the armrest 10 is in the storage position. As a result, the seated person may feel uncomfortable with the wire harness 14 as a foreign object.

  However, in this embodiment, since the wire harness 14 is routed on one end side in the width direction of the armrest box 15, no load acts on the wire harness 14, and the seated person is not discomforted.

  A through hole 15D through which the wire harness 14 can pass is provided on the first box portion 15A side of the second box portion 15B (see FIG. 7). Thereby, the said wire harness 14 can be easily connected to an electric equipment, suppressing that the curvature of the wire harness 14 becomes large.

  And the holder | retainer 16 for hold | maintaining the wire harness 14 and the projection part 17 to which the holder | retainer 16 was fixed are provided (refer FIG. 9). Thereby, it can suppress that the wire harness 14 moves at the time of the mounting | wearing process which mounts the shock absorbing material 13 in the armrest box 15. FIG. Therefore, it is possible to realize an increase in the size of the first storage space 11A while suppressing an increase in the number of assembly steps of the armrest 10.

  That is, when the armrest 10 is assembled, first, the wire harness 14 is placed on the armrest box 15 in a state where the opening portions of the first storage space 11A to the third storage space 11C face downward by the assembly operator. Attached and fixed to the box 15.

  Next, as shown in FIG. 4, the armrest box 15 to which the wire harness 14 is fixed is assembled by the assembly operator so as to be fitted into the cushioning material 13. The buffer material 13 is molded in advance into a predetermined shape.

  For this reason, if the wire harness 14 is not fixed to the armrest box 15 when the fitting operation is performed, the wire rests when the armrest box 15 is fitted into the molded cushioning material 13. There is a possibility that the harness 14 meanders with a large deviation from a predetermined position (for example, the position shown in FIG. 5).

  And if the wire harness 14 meanders greatly, there is a possibility that the wire harness 14 will not reach the electrical device (second storage space 11B) or that problems such as deterioration in workability of connection between the wire harness 14 and the electrical device may occur. Get higher.

  On the other hand, in the present embodiment, the armrest box 15 is fitted into the molded cushioning material 13 in a state where the wire harness 14 is fixed to the armrest box 15 via the cage 16 and the protrusion 17. The above problems are unlikely to occur. As a result, it is possible to increase the size of the first storage space 11 </ b> A while suppressing an increase in the number of assembly steps of the armrest 10.

  In addition, when the wire harness 14 is attached, the assembly operator can attach and fix the wire harness 14 to the armrest box 15 from above. Therefore, the assembly operator can attach the wire harness 14 to the armrest box 15 if the wire harness 14 is visually observed.

  A gap portion 17C is provided in a range from the connecting portion 17B between the protruding portion 17 and the armrest box 15 to the other end in the extending direction of the protruding portion 17 (see FIG. 10). Thereby, in the site | part which comprises the inner wall of 11 A of 1st storage spaces among the 1st box parts 15A, it can suppress that the distortion resulting from "sink" etc. at the time of shaping | molding generate | occur | produces.

  That is, if the protrusion 17 is integrated with the first box portion 15A in the entire extending direction, a portion of the first box portion 15A where the protrusion 17 is provided (hereinafter referred to as a protrusion forming portion). ) Is thicker than other parts.

  For this reason, in the projection forming portion of the portion constituting the inner wall of the first storage space 11A, distortion due to “sink” or the like is likely to occur at the time of resin molding. Distortion is likely to occur in the projection forming portion.

  However, since the gap 17C is provided in the range from the connecting portion 17B to the other end in the extending direction of the projection 17 in the projection 17 according to the present embodiment, the first gap is provided in the range where the gap 17C is provided. The wall thickness dimension of one box portion 15A can be made substantially constant.

Therefore, it is possible to suppress the occurrence of distortion caused by “sink” or the like in a portion constituting the inner wall of the first storage space 11A in the first box portion 15A.
And the connection part 17B which concerns on this embodiment is provided in the height direction upper end side. Thereby, it can suppress that the fixed strength of the wire harness 14 falls.

  In other words, in the present embodiment, the gap portion 17C is provided in order to suppress the occurrence of distortion at the site constituting the inner wall of the first storage space 11A. For this reason, the protrusion part 17 becomes a cantilever shape.

  In other words, since there is no connecting portion 17B in the portion of the protrusion 17 that is sandwiched between the sandwiching portions 16A, that is, the portion where the load is applied to the protrusion 17, the protrusion 17 is greatly bent in the longitudinal direction (the front-rear direction of the seat). There is a risk of deformation.

  On the other hand, since the opening of the first storage space 11A is provided on the upper end side in the height direction of the first box portion 15A, a cross section on the upper end side in the height direction in order to ensure the rigidity of the entire first box portion 15A. The secondary moment is larger than the lower end in the height direction.

  Since the portion provided with the connecting portion 17B has high rigidity, the protruding portion 17 is greatly bent and deformed at the lower end in the height direction where the connecting portion 17B is not provided, that is, at the other end in the extending direction of the protruding portion 17. Can be suppressed.
