本考案はヘツドレスト本体のステーをシートバ
ツクフレームに回動自在に取付けて、前後方向に
移動調整可能なヘツドレストの改良に関するもの
である。[Detailed Description of the Invention] The present invention relates to an improvement of a headrest that can be moved and adjusted in the longitudinal direction by rotatably attaching the stay of the headrest main body to the seat back frame.
この種のヘツドレストを第１図に示す。斯る従
来品はシートバツクフレーム１′，１′に縦に固着

ツドレスト本体ａの前後移動に伴つてピン３a′，
３b′が上下に変化し、前後位置によつてヘツドレ
ストの高さが異なるため、ヘツドレストの位置を
前後に調整した後、高さを調整しなければならな
い不具合があつた。 This type of headrest is shown in FIG. Such a conventional product is composed of two brackets 2' vertically fixed to the seat back frames 1', 1', and a pair of arms 3' supporting the headrest main body a.
A pin 3b' for longitudinal positioning of the headrest main body a is protruded from the upper side of the pair of arms 3', 3', and a pin 3a' for a fulcrum serving as a center of rotation is protruded from the lower side. 3b' is inserted into the wave-shaped lock opening 2b' provided in the bracket 2', and the pin 3a' is inserted into the elongated hole 2a' of the bracket 2', so that the headrest main body a is rotated in the front-back direction around the pin 3a'. Locking is achieved by engaging the moving pin 3b' in an appropriate position of the lock opening 2b'.
Therefore, since the headrest body a rotates around the pin 3a', the range of movement in the front and back direction becomes large, but as the headrest body a moves back and forth, the pins 3a',
3b' changes up and down, and the height of the headrest differs depending on the front and rear positions, so there was a problem that the height had to be adjusted after the position of the headrest was adjusted back and forth.
そこで、本考案は斯様な従来品の不具合を除去
することを目的とするものである。 Therefore, the present invention aims to eliminate such defects of conventional products.
以上の目的を達成するための本考案の基本的構
成はヘツドレスト本体の支持部材と多数のロツク
溝付のロツク板とを二枚のブラケツト間に架設し

動に伴つてロツク板が回動し、そのロツク板の適
宜位置のロツク溝にブラケツトに設けたストツパ
が係合するようにしたものである。 The basic structure of the present invention to achieve the above object is to fix the supporting member of the headrest main body and a lock plate with a large number of lock grooves to a rotating shaft installed between two brackets, The lock plate rotates as the bracket moves back and forth, and a stopper provided on the bracket engages with a lock groove at an appropriate position on the lock plate.
従つてヘツドレスト本体の前後動によつてヘツ
ドレスト本体が従来品の如き上下に移動すること
がないため、ヘツドレストを前後に調整した後、
上下に調整する必要がない。依つて、ヘツドレス
ト本体はシートバツク内の回動軸を中心に回動す
るため前後の方向の移動調整可能範囲が広い従来
品の長所を損うことなく従来品の不具合を除去で
きる。 Therefore, as the headrest body moves back and forth, the headrest body does not move up and down like in conventional products, so after adjusting the headrest back and forth,
No need to adjust up or down. Therefore, since the headrest main body rotates around the rotation axis within the seat bag, the disadvantages of the conventional product can be eliminated without sacrificing the advantage of the conventional product, which has a wide adjustable range of movement in the front and rear directions.

体ａは前方第一段目に移動する。 FIG. 5A shows the headrest main body a in a neutral state. In this state, the stopper 7 engages with the locking groove 51a of the locking plate 5, and this engaged state is maintained by a spring 74. On the other hand, the return plate 6 is rotatable because the pin 52 is located at the rear of the large elongated hole 21. Next, when the headrest main body a is pushed forward, the rotation shaft 4 rotates, and the lock plate 5 also rotates and the stopper 7 engages with the lock groove 51b of the lock plate 5, so that the headrest The main body a moves to the first stage forward.

しロツクされる。 In this state, the pin 52 of the locking plate 5 is located approximately at the center of the large elongated hole 21, so the return plate 6 is rotatable (FIG. 5B). When the headrest main body a is further pushed forward, it moves to the second forward position and the pin 52 is located at the frontmost end of the large elongated hole 21. 7 (FIG. 5C). Next, if you further push the headrest body a forward,
The stopper 7 engages with the lock release/return start protrusion 51d of the lock plate 5, and the pin 52 pushes the return plate 6, and the pin 73 of the stopper 7
moves over the sliding portion 62 and into the locking stepped portion 63. Therefore, in this state, the engagement state (lock) of the stopper 7 is released, so that the headrest body a becomes freely movable in the front-back direction (FIG. 5D). Then, when the headrest main body a is returned to the rear, that is, the neutral position, the small elongated hole 6 of the return plate 6
1 is shorter than the large elongated hole 21 of the bracket 2, the return plate 6 is moved by the pin 52 (FIG. It engages with the lock groove 51a of the lock plate 5 and is locked.

調節操作が簡単で操作性が頗る良い。 Since the present invention is constructed as described above, the height of the headrest does not change due to the back and forth movement of the headrest as in conventional products. Therefore, since no height adjustment is required, the operation is simple, quick, and convenient. Moreover, compared to conventional products, it has a simpler structure and can be provided at a lower cost. In addition, since the center of rotation of the headrest is located within the seat bag, the advantages of conventional products such as the need for a lock release lever with a wide range of movement in the longitudinal direction are not lost. Furthermore, since the present invention uses the above-mentioned lock release mechanism, the front and back position of the headrest can be adjusted by simply pushing the headrest main body forward. Therefore, the adjustment operation of the front and rear positions of the headrest is easy and has excellent operability.
