However, it is preferable that the connecting structure (the connecting portion 20 and the connected portion 22) have a material that generates an appropriate frictional force by surface contact between both members. Examples of this type of material include resin (natural resin, synthetic resin), rubber (natural rubber, synthetic rubber), and elastomer.

(連結部)
連結部20は、第二部位12に設けられる球状部位(断面円形状)であり、第一取付け部位20aを有する。
第一取付け部位20aは、短尺な棒状部位であり、連結部20一側から突出する。第一取付け部位20aの径寸法は、連結部20の中央部分の径寸法よりも小さく設定できる。

そして本実施例の被連結部22は、適度な可撓性を有する部材であり、連結部20の挿入により撓み変形(拡開)可能である。このため開口部位22bを連結部20にて押圧しつつ拡開させることで、被連結部22内に連結部20を嵌装可能である。また被連結部22に連結部20を嵌装したのち、被連結部22が元の状態に復元することで連結部20(球状)を内接状態で保持できる。
(Connected part)
The coupled portion 22 is a concave portion (a space portion having a circular cross section) provided in the first portion 11 and has a second attachment portion 22a.
The second attachment portion 22a is a short rod-like portion (dense or hollow) and protrudes from one side of the connected portion 22. Moreover, the to-be-connected part 22 is a space part (substantially spherical) in which the connecting part 20 can be fitted, and has an opening part 22b (substantially circular) on one end side. The opening dimension of the opening part 22b can be set smaller than the diameter dimension of the central part of the connecting part 20.

And the opening part 22b is exposed from the 1st part 11, and it arrange | positions so that connection to the connection part 20 is possible.
And the to-be-connected part 22 of a present Example is a member which has moderate flexibility, and can be bent and deformed (expanded) by the insertion of the connecting part 20. For this reason, the connecting portion 20 can be fitted into the connected portion 22 by expanding the opening portion 22 b while pressing the connecting portion 20. Moreover, after fitting the connection part 20 to the to-be-connected part 22, the to-be-connected part 22 can hold | maintain the connection part 20 (spherical) in an inscribed state by decompress | restoring to the original state.

[第一部位と第二部位の連結(維持機構の形成)]
図1及び図2を参照して、第一部位11と第二部位12を、連結構造20,22を介して連結することにより、アームレスト10を途中で屈曲可能とする。
このとき第一部位11の先端(着座側)に第二部位12を配置しつつ、連結部20(球状)を、被連結部22に回転可能に嵌装する。そして被連結部22に連結部20を嵌装して内接(面接触)させることにより、両部の相対回転時において適度な摩擦を生ずる(維持機構としての摩擦力が生ずる)。この摩擦力(維持機構)により、第一部位11と第二部位12の相対位置関係(屈曲状態等)を維持できる。
ここで摩擦力の大きさは特に限定しないが、乗員手首部を第二部位12にて支持する際に、第一部位11と第二部位12の相対位置関係を維持できる程度の摩擦力であることが好ましい。第二部位12にて乗員手首部を支持することで、例えば乗員が、比較的に楽に携帯電話等を操作できる(使い勝手に優れる構成となる)。
[Connection of first part and second part (formation of maintenance mechanism)]
With reference to FIGS. 1 and 2, the armrest 10 can be bent halfway by connecting the first portion 11 and the second portion 12 via the connecting structures 20 and 22.
At this time, the connecting portion 20 (spherical) is rotatably fitted to the connected portion 22 while the second portion 12 is disposed at the tip (sitting side) of the first portion 11. Then, by fitting the connecting portion 20 to the connected portion 22 and inscribed (surface contact), appropriate friction is generated at the time of relative rotation of both portions (a frictional force as a maintenance mechanism is generated). By this frictional force (maintenance mechanism), the relative positional relationship (bent state or the like) between the first part 11 and the second part 12 can be maintained.
Here, although the magnitude of the frictional force is not particularly limited, the frictional force is such that the relative positional relationship between the first part 11 and the second part 12 can be maintained when the occupant wrist is supported by the second part 12. It is preferable. By supporting the occupant wrist at the second portion 12, for example, the occupant can operate the mobile phone or the like relatively easily (having a configuration excellent in usability).

[アームレストの形状変更]
そして被連結部22に対して連結部20(球状)を相対回転させて、第一部位11に対する第二部位12の相対位置関係を変更する(図2の太線で示す矢印を参照)。
例えば本実施例では、被連結部22と連結部20(球状)を相対回転させることで、第二部位12を、第一部位11に対してシート上下及び内外に屈曲できる。また第二部位12を、第一部位11に対してアームレスト10の軸周りに回転できる。そして維持機構(摩擦力)により、第一部位11と第二部位12の相対位置関係を維持することで、アームレスト10の形状を自在に変更できる。
[Change armrest shape]
Then, the connecting portion 20 (spherical) is rotated relative to the connected portion 22 to change the relative positional relationship of the second portion 12 with respect to the first portion 11 (see the arrow indicated by the thick line in FIG. 2).
For example, in the present embodiment, the second portion 12 can be bent up and down and in and out of the seat with respect to the first portion 11 by relatively rotating the connected portion 22 and the connecting portion 20 (spherical). Further, the second portion 12 can be rotated around the axis of the armrest 10 with respect to the first portion 11. The shape of the armrest 10 can be freely changed by maintaining the relative positional relationship between the first part 11 and the second part 12 by the maintenance mechanism (friction force).

以上説明したとおり本実施例によれば、第一部位11に対する第二部位12の相対位置関係を変更することにより、アームレスト10の形状を自在に変更できる。
また本実施例では、連結部20と被連結部22の間の摩擦力(比較的シンプルな機構)により、第一部位11に対する第二部位12の状態を維持することができる。
このため本実施例によれば、アームレスト10の使い勝手をより向上させることができる。
As described above, according to the present embodiment, the shape of the armrest 10 can be freely changed by changing the relative positional relationship of the second part 12 with respect to the first part 11.
In the present embodiment, the state of the second portion 12 relative to the first portion 11 can be maintained by the frictional force (relatively simple mechanism) between the connecting portion 20 and the connected portion 22.
For this reason, according to the present Example, the usability of the armrest 10 can be improved more.

(4)また本実施形態では、維持機構を、連結構造20,22に設ける例を説明した。これとは異なり維持機構を、連結構造とは別の機構として第一部位と第二部位に設けることができる。例えば第一部位と第二部位を連結する棒状部材を維持機構として使用できる。そして棒状部材の一端を第一部位に相対移動不能に連結するとともに、棒状部材の他端を第二部材に相対移動不能に連結することで、両部位の相対位置関係を維持する。
(3) Moreover, in this embodiment (modification), the other 2nd site | part 12B demonstrated the example which has the connection site | part 20x and the to-be-connected site | part 22x. In contrast to this, only one kind of the connecting part 20x (or the connected part 22x) can be formed at both ends of the other second part 12B. In this case, the first part 11 and the second part 12A have a part (the connecting part 20 or the connected part 22) that can be connected to the other second part 12B.
(4) Moreover, in this embodiment, the example which provides a maintenance mechanism in the connection structures 20 and 22 was demonstrated. In contrast, the maintenance mechanism can be provided in the first part and the second part as a mechanism different from the connection structure. For example, a rod-shaped member that connects the first part and the second part can be used as the maintenance mechanism. And while connecting the other end of a rod-shaped member to a 1st site | part so that relative movement is impossible, and connecting the other end of a rod-shaped member to a 2nd member so that relative movement is impossible, the relative positional relationship of both site | parts is maintained.

(5)また本実施形態では、一対のアームレスト10をシートバック6に取付ける例を説明したが、単数のアームレスト10を取付けることができる。 (5) In the present embodiment, the example in which the pair of armrests 10 is attached to the seat back 6 has been described, but a single armrest 10 can be attached.
