（第１実施形態）
以下に、この発明の第１実施形態を、図１〜図４に基づいて説明する。
図１及び図２に示すように、自動車用シート１１の背もたれ部１２の上端部にはヘッドレスト１３が配設されている。このヘッドレスト１３は、ヘッドレスト本体１４と正面形ほぼ逆Ｕ字状のステー１５とを備えている。ヘッドレスト本体１４は、袋状の表皮１６内にステー１５の基部１５ａ及び両脚部１５ｂの上端部を挿入するとともに、弾性パッドとしての発泡弾性材１７を充填して構成されている。表皮１６内の後部には前部側からの荷重を受けるための丈夫な剛体よりなる保持板１８が配設されている。 (First embodiment)
Below, 1st Embodiment of this invention is described based on FIGS. 1-4.
As shown in FIGS. 1 and 2, a headrest 13 is disposed at the upper end portion of the backrest portion 12 of the automobile seat 11. The headrest 13 includes a headrest main body 14 and a front-side substantially inverted U-shaped stay 15. The headrest body 14 is configured by inserting a base 15a of a stay 15 and upper ends of both leg portions 15b into a bag-shaped skin 16 and filling a foamed elastic material 17 as an elastic pad. A holding plate 18 made of a strong rigid body for receiving a load from the front side is disposed at the rear part in the skin 16.

図１及び図３に示すように、前記ヘッドレスト本体１４内において、ステー１５の両脚部１５ｂには一対の支持レバー１９が基端部にて回動可能に取り付けられている。ヘッドレスト本体１４の両側外部において、両支持レバー１９の先端部には一対のサポート部材２０が支持されている。各サポート部材２０は、袋状の表皮２１内に発泡弾性材２２を充填して構成されている。そして、両支持レバー１９がステー１５の脚部１５ｂを中心に回動されることにより、これらのサポート部材２０が図３に実線で示す後方の退避位置と、鎖線で示す前方の作用位置とに移動配置されるようになっている。   As shown in FIGS. 1 and 3, in the headrest body 14, a pair of support levers 19 are attached to both leg portions 15 b of the stay 15 so as to be rotatable at base end portions. A pair of support members 20 are supported at the tip portions of the support levers 19 outside the both sides of the headrest body 14. Each support member 20 is configured by filling a foamed elastic material 22 in a bag-shaped skin 21. Then, when both the support levers 19 are pivoted about the leg portions 15b of the stay 15, the support members 20 are moved to a rearward retracted position indicated by a solid line in FIG. 3 and a forward action position indicated by a chain line. It is designed to move.

図１、図３及び図４に示すように、前記ヘッドレスト本体１４の発泡弾性材１７内の内部には前部から後部にかけて空間部１７ａが形成され、その空間部１７ａの内部には、移動部材２３がシート部材２４にて包囲した状態で前後方向へ移動可能に配設されている。前記シート部材２４は、移動部材２３の移動によって発泡弾性材１７の内面が崩れるのを防止するためのものである。そして、通常時には発泡弾性材１７の弾発力により、移動部材２３がヘッドレスト本体１４内の前方位置に保持され、着座者がヘッドレスト本体１４に頭部をあずけたときには、移動部材２３が頭部によって押圧されて前方位置から後方位置に移動されるようになっている。従って、発泡弾性材１７は、移動部材２３を前方へ付勢するための付勢手段を構成している。   As shown in FIGS. 1, 3 and 4, a space 17a is formed in the foamed elastic material 17 of the headrest body 14 from the front to the rear, and a moving member is formed in the space 17a. 23 is disposed so as to be movable in the front-rear direction while being surrounded by the sheet member 24. The sheet member 24 is for preventing the inner surface of the foamed elastic material 17 from being broken by the movement of the moving member 23. In the normal state, the moving member 23 is held at the front position in the headrest main body 14 by the elastic force of the foamed elastic member 17, and when the seated person places the head on the headrest main body 14, the moving member 23 is moved by the head. It is pressed and moved from the front position to the rear position. Therefore, the foamed elastic material 17 constitutes an urging means for urging the moving member 23 forward.

前記移動部材２３と両サポート部材２０との間には、移動部材２３の後方移動を両サポート部材２０に対しその前方移動として伝達するための歯車機構を利用した伝達手段としての伝達機構２５が設けられている。すなわち、移動部材２３の両側面には一対のラック２６が形成されている。これらのラック２６と噛み合うように、両支持レバー１９の基端部にはピニオン２７が形成されている。そして、移動部材２３が前方位置から後方位置に移動されたとき、ラック２６及びピニオン２７を介して両支持レバー１９が回動され、両サポート部材２０が後方の退避位置から前方の作用位置に回動されるようになっている。   Between the moving member 23 and the two support members 20, a transmission mechanism 25 is provided as a transmission means using a gear mechanism for transmitting the backward movement of the moving member 23 to the two support members 20 as the forward movement thereof. It has been. That is, a pair of racks 26 are formed on both side surfaces of the moving member 23. Pinions 27 are formed at the base ends of the support levers 19 so as to mesh with these racks 26. When the moving member 23 is moved from the front position to the rear position, the both support levers 19 are rotated via the rack 26 and the pinion 27, and the both support members 20 are rotated from the rearward retracted position to the front acting position. It comes to be moved.

次に、前記のように構成されたヘッドレストの作用を説明する。
さて、このヘッドレスト１３の通常時、すなわち移動部材２３が後方へ押圧されていないときには、図３に示すように、移動部材２３が発泡弾性材１７の弾発力により、ヘッドレスト本体１４内の前方位置に配置されている。この場合、図３に実線で示すように、両サポート部材２０は伝達機構２５を介して、ヘッドレスト本体１４の両側後方の退避位置に配置されている。この状態で、着座者が仮眠を取ったりくつろいだりするために、頭部をヘッドレスト本体１４にあずけると、その頭部により移動部材２３が押圧されて、前方位置から後方位置に移動される。これにより、伝達機構２５のラック２６及びピニオン２７を介して、両支持レバー１９がステー１５を中心に回動され、図３に鎖線で示すように、両サポート部材２０がヘッドレスト本体１４の両側前方の作用位置に移動される。よって、この状態でヘッドレスト本体１４及び両サポート部材２０により、着座者の頭部を後方及び両側方から効果的に支持することができる。 Next, the operation of the headrest configured as described above will be described.
When the headrest 13 is in a normal state, that is, when the moving member 23 is not pressed backward, the moving member 23 is moved forward by the elastic force of the foamed elastic member 17 as shown in FIG. Is arranged. In this case, as shown by a solid line in FIG. 3, the both support members 20 are disposed at the retracted positions on both rear sides of the headrest body 14 via the transmission mechanism 25. In this state, in order for the seated person to take a nap or relax, when the head is moved to the headrest body 14, the moving member 23 is pressed by the head and moved from the front position to the rear position. As a result, both support levers 19 are pivoted about the stay 15 via the rack 26 and the pinion 27 of the transmission mechanism 25, and the two support members 20 are moved forward on both sides of the headrest body 14 as shown by the chain line in FIG. 3. Is moved to the position of action. Therefore, in this state, the headrest body 14 and the two support members 20 can effectively support the seated person's head from behind and from both sides.

また、この状態から運転等のために着座者の頭部がヘッドレスト本体１４から離されると、移動部材２３がその後方の発泡弾性材１７の弾性により後方位置から前方位置に復帰移動される。これにより、伝達機構２５のラック２６及びピニオン２７を介して、両支持レバー１９が前記と反対方向に回動され、両サポート部材２０が作用位置から退避位置に復帰移動される。よって、この状態でサポート部材２０が着座者の両側方の視界を邪魔するおそれはなく、広い視界のもとで運転を行うことができる。以上のように、このヘッドレスト１３においては、両サポート部材２０を手動操作する必要がなく、後方の退避位置と前方の作用位置とに容易に移動配置することができる。   Further, when the seated person's head is separated from the headrest main body 14 for driving or the like from this state, the moving member 23 is returned and moved from the rear position to the front position by the elasticity of the foamed elastic material 17 behind it. As a result, both support levers 19 are rotated in the opposite direction to the above via the rack 26 and the pinion 27 of the transmission mechanism 25, and both support members 20 are returned from the operating position to the retracted position. Therefore, in this state, there is no possibility that the support member 20 disturbs the field of view on both sides of the seated person, and driving can be performed under a wide field of view. As described above, in the headrest 13, it is not necessary to manually operate both the support members 20, and the headrest 13 can be easily moved and arranged between the rearward retracted position and the forward acting position.

以上のように、この実施形態では以下の効果を発揮する。
・ 着座者が頭部に位置を変えるのみで、両サポート部材２０を簡単に移動操作でき、その着座者がサポート部材２０の移動操作のために無理な姿勢を強いられることはない。 As described above, this embodiment exhibits the following effects.
-Both the support members 20 can be easily moved by simply changing the position of the seated person to the head, and the seated person is not forced to take an unreasonable posture for the moving operation of the support member 20.

・ 着座者が頭部を後部側の位置から前部側の位置に戻すのみで、発泡弾性材１７の弾性を利用して移動部材２３を前方へ復帰移動するようにしたので、前述したように操作が簡単であるばかりでなく、移動部材２３を前方へ戻すための専用のバネが不要となり、構成が簡単である。   -Since the seated person returns the head from the position on the rear side to the position on the front side, the moving member 23 is returned to the front by using the elasticity of the foamed elastic material 17, so as described above. Not only is the operation simple, but a dedicated spring for returning the moving member 23 to the front is not required, and the configuration is simple.

・ ヘッドレスト本体１４の後部に丈夫な剛体よりなる保持板１８を設けたため、ヘッドレスト本体１４の前面が強圧されたとしても、移動部材２３の必要以上の後方移動が規制され、ヘッドレスト１３を快適に使用できる。   Since the holding plate 18 made of a strong rigid body is provided at the rear part of the headrest main body 14, even if the front surface of the headrest main body 14 is strongly pressed, the rearward movement of the moving member 23 is restricted more than necessary, and the headrest 13 is used comfortably. it can.
