【発明の詳細な説明】
〈産業上の利用分野〉
本発明は自動車や航空機等の座席に使用するヘッドレス
ト装置に関するものである。DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a headrest device used in seats of automobiles, airplanes, etc.
〈従来の技術〉
従来の此種装置は、人体の頭部を支承する受部を弾性層
、例へば発泡ポリウレタン等の成形品で構成して、その
内部に心枠等の支承体を埋設して作っている。<Prior art> In conventional devices of this type, the receiving part that supports the head of the human body is made of an elastic layer, for example, a molded product such as foamed polyurethane, and a supporting body such as a core frame is embedded inside the receiving part. I'm making it.
〈発明が解決しようとする問題点〉
この様なヘッドレスト装置にあっては、人体の頭部が弾
性層で受けられるから、追突等の如く頭部に急激且つ強
い衝撃が加はると、頭部が一旦弾性層内に没入し、次い
でこの弾性層の反発力で前方に押圧される事になるから
、弾性層の反発力が該層全体の衝撃力吸収効果を悪くす
ると云う問題がある。<Problems to be solved by the invention> In such a headrest device, the head of the human body is supported by the elastic layer, so if a sudden and strong impact is applied to the head, such as in a rear-end collision, the head will be damaged. Since the part is once immersed into the elastic layer and then pressed forward by the repulsive force of this elastic layer, there is a problem that the repulsive force of the elastic layer deteriorates the impact force absorption effect of the entire layer.

吸収する様に構成しである。Means for Solving the Problems> In the device of the present invention, a gel substance is filled in the head holder, and an elastic supporting wall with small cushioning properties is formed behind the head receiving part, and further behind this elastic supporting wall there is a gel material. A base with large cushioning properties is arranged, and the above-mentioned three-layer structure is configured to attenuate and absorb impact.

るから１頭部の受ける反発弾性力を少く出来る。In the device of the present invention, the impact applied to the head of the human body is absorbed by the inelastic deformation of the gel material layer, and is also absorbed by the elastic deformation of the elastic support wall and the flexible and large elastic deformation of the base that receives the impact. In addition, since the restoring repulsive force between the base and the elastic supporting wall reaches the head while being absorbed by the inelastic deformation of the gel material layer, the repulsive elastic force received by one head can be reduced.

たゲル物質層６とを備えて構成されている。Embodiment Examples As shown in FIG. 1, the headrest device of the present invention includes six frames 1 made of a hard material such as metal and attached to a seat (not shown), and is made so that the six frames 1 are buried. An elastic base 2 with high cushioning properties, for example, a pillow body made of foamed polyurethane resin or foamed polyethylene resin, which is foam-molded 60 times, and an elastic support wall 3 with low cushioning properties, layered on the front surface of the base 2, for example. The layer made of the foamable resin is foam-molded to about 30 times the size, and the head receiving surface 4 is formed by expanding a flexible fabric, for example, a sheet material made of urethane resin, on the front surface of the elastic support wall 3. A gel material layer 6 is formed by filling a gel material into a cavity 5 formed between the elastic support wall 3 and the head receiving surface 4.
上記ゲル物質層６を形成するゲル物質は計度５０〜２０
０、特に計度１００〜２００のものが望ましく、計度が
あまり小さいと衝撃吸収力が劣下するし、又計度が大き
すぎると頭部に加はる反力が問題になる。The gel material forming the gel material layer 6 has a total weight of 50 to 20
0, particularly preferably one with a scale of 100 to 200. If the scale is too small, the shock absorbing power will deteriorate, and if the scale is too large, the reaction force applied to the head will become a problem.
本発明装置はこの様なものであるから、例へば自動車の
運転中に追突されたとすると、人体の頭部はゲル物質層
６を急激に変形させつつ低クッション性の弾性支壁３を
変歪せしめ、同時にこの支壁３の変歪で基部２内に没入
していく。Since the device of the present invention is as described above, for example, if a car is hit from behind while driving, the head of the human body will rapidly deform the gel material layer 6 and distort the elastic support wall 3 with low cushioning properties. At the same time, the supporting wall 3 sinks into the base 2 due to deformation.
この時、上記ゲル物質層６は非弾性変形によって人体頭
部から受ける衝撃力を吸収しつつ支壁３を変歪させるか
ら、人体頭部に加はる衝撃瞬間の反力による反発力は小
さくて済む。At this time, the gel material layer 6 deforms the support wall 3 while absorbing the impact force received from the human head through inelastic deformation, so that the repulsive force due to the reaction force applied to the human head at the moment of impact is small. It's done.
上記衝撃力によって基部２と支壁３とが変形して衝撃力
を吸収した後には、基部２と弾性支壁３が有する復元力
は反発力として頭部に作用し、頭部を前方に弾発する事
になるが、この場合にもゲル物質層６の変形は非弾性変
形であるから１頭部に対する反発弾性力を減衰させる作
用がある。After the base 2 and the supporting wall 3 are deformed by the impact force and absorbing the impact force, the restoring force of the base 2 and the elastic supporting wall 3 acts on the head as a repulsive force, causing the head to bounce forward. However, in this case as well, the deformation of the gel material layer 6 is inelastic deformation, so it has the effect of attenuating the repulsion elastic force against one head.
従って、人体頭部に加はる弾性力に起因する瞬間的な力
はゲル物質層６の変形で効果的に減衰せしめられる喜に
なる。Therefore, the instantaneous force caused by the elastic force applied to the human head can be effectively attenuated by the deformation of the gel material layer 6.
以上の処において本発明装置は第２図の如く、弾性基部
２と弾性支壁３とを別個に作って、これを組合せても良

良く、この場合には空室５内にゲル物質を充填した後に
空室５を弾性片５１で密閉して枕体Ａを作り、この枕体
Ａを基部２に取付ける様にすれば良い。In the above, the device of the present invention may be configured such that the elastic base 2 and the elastic support wall 3 are made separately and combined as shown in FIG. In this case, after filling the void 5 with a gel substance, the void 5 is sealed with an elastic piece 51 to form a pillow body A, and this pillow body A is attached to the base 2. Just do it.
この様に枕体Ａを別個に作った場合には、枕体Ａの弾性
片５１が頭受面４を形成する様にしても良いが、通常は
枕体Ａと基部２とを１体に包覆する外被層４１の前面部
分が頭受面４として使用される。When the pillow body A is made separately in this way, the elastic piece 51 of the pillow body A may form the head support surface 4, but normally the pillow body A and the base 2 are made into one body. The front part of the enveloping outer covering layer 41 is used as the head receiving surface 4.

効果がある。<Effects of the Invention> As described above, since the device of the present invention is provided with the gel material layer 6 that absorbs shock through inelastic deformation behind the head receiving surface 4 that receives the human head, A car has been created that absorbs sudden shocks without producing any repulsive force. Therefore, even if the impact force applied to the human head is instantaneously strong, such as in a rear-end collision, this is absorbed by the repulsive force. This has the effect that it can be transmitted to the base 2 side while being well attenuated without causing any increase in the amount.
