【考案の詳細な説明】
本考案は自動車等の座席に設ける前後調整可能
なヘツドレストに関するものでる。[Detailed Description of the Invention] The present invention relates to a front-rear adjustable headrest provided on a seat of an automobile or the like.
従来例えば自動車の座席には、衝突による乗員

ツドレストを取り付けているが、乗員の着座姿勢
によりヘツドレストと乗員の頭部との間に大きな
間隙が生じ、衝突の際に頭部の振幅が大きくなる
ためむち打ち症になり易いという問題があつた。
近年になり乗員の着座姿勢に合せてヘツドレスト
を前後方向に調整する装置が開発されたが、これ
らの機構は平行リンクやスライドレールを用いて
いるため、いずれも構造が複雑で高価なものとな
り、重量が大きいため背もたれの重心が高くなり
座席全体の強度を弱くする欠点を有している。 Conventionally, for example, a headrest is attached to the upper part of the backrest of a car seat in order to prevent occupants from getting whiplash in the event of a collision. There was a problem in that the amplitude of the head becomes large during this time, making it easy to suffer from whiplash.
In recent years, devices have been developed to adjust the headrest in the longitudinal direction according to the seating position of the occupant, but these mechanisms use parallel links and slide rails, making them complex and expensive. Due to the large weight, the center of gravity of the backrest becomes high, which weakens the overall strength of the seat.
本考案は乗員の着座姿勢に合せてヘツドレスト
の前後位置を微調整することにより、衝突時に乗
員の頭部や頚部を保護するもので、軽量且つ簡単
な構造で操作性の良いヘツドレストを提供するも
のである。 This invention protects the occupant's head and neck in the event of a collision by finely adjusting the front and back position of the headrest according to the occupant's seating posture, and provides a headrest that is lightweight, simple in structure, and easy to operate. It is.

隔を適正に保つように構成されている。 Embodiments of the present invention will be described below with reference to FIGS. 1 to 3. The seat 1 consists of a seat 2 and a backrest 3, and the backrest 3 is tilted in the front-rear direction with respect to the seat 2 by a reclining device 4. Reference numeral 5 denotes a head rest with an adjustment knob 6 provided on the side. It is attached to the upper part of the backrest 3 by a stay 7, and by rotation of the adjustment knob 6, the headrest 5 is adjusted to the backrest 3.
It is configured to move in the front-rear direction relative to the passenger P and maintain an appropriate distance from the head H of the occupant P.

ている。 As shown in FIGS. 2 and 3, the headrest 5 includes an inner frame 8 to which the upper end of the stay 7 is fixed by welding, a horizontal member 81, a front support member 82 standing up on both sides of the horizontal member 81 , and a rear support member 82 . Part 8
Consists of 3 . On one of the left and right sides of the inner frame 8, a front support member 8 2 and a rear support member 8 3 are provided.
Guides 9 1 and 9 2 are fixedly installed in each of the guides 9 1 and 9 2 , and the adjustment knob 6 into which the threaded rod 10 is screwed is held between the guides 9 1 and 9 2 . On the other hand, both ends of a slider 12 fitted with a sliding rod 11 provided parallel to the threaded rod 10 are locked to a front support member 82 and a rear support member 83 . An outer frame 13 formed in an inverted U shape is fixedly supported by both ends of a screw rod 10 and a sliding rod 11, and its outside is covered with a pad material 14 and a skin material 15.

At this time, since a forward force also acts on the sliding rod 11 provided parallel to the threaded rod 10, the outer frame 13 moves linearly forward. Therefore, the headrest 5 moves forward by a necessary distance with respect to the backrest 3, thereby properly protecting the occupant's head. Also headrest 5
If you want to move it backwards, you just need to turn the adjustment knob 6 counterclockwise (in the opposite direction to arrow X).

ヘツドレストである。 As described above, the present invention fixes an inner frame having a pair of front and rear support members to a stay, and attaches guides to each support member to hold both sides of an adjustment knob that is screwed into one of the left and right ends of the inner frame. A slider with a sliding rod fitted on the other side is fixed to a supporting member, and both ends of the screw rod and sliding rod are fixed to an outer frame formed in an inverted U shape, and the outer frame is made of pad material. Since the head rest is covered with a skin material, the head rest can move back and forth linearly without changing its angle, and can be finely adjusted to match the seating posture of the occupant, so the optimal position can always be secured. Furthermore, since the number of parts is small and the structure is simple, it can be manufactured at low cost, and the mechanical parts do not rattle or break even after repeated use, making the headrest of great practical value.
