【考案の詳細な説明】
本考案は例えば自動車の座席前方に配し衝突事故の際に
自動的に作動膨張して乗員を拘束し乗員が硬い部位に衝
突し、傷害を受けるのを防止するエアクッション装置に
釦けるクッションカバーに関するものである。[Detailed description of the invention] This invention is an air system that is placed in front of the seat of a car, for example, and in the event of a collision, automatically operates and inflates to restrain the occupant and prevent the occupant from colliding with a hard part and sustaining injury. This invention relates to a cushion cover that can be attached to a cushion device.
従来この種のクッションカバーは第１図に示すように、
表皮１と鉄板、樹脂板、金網等からなる芯材２を内包し
たパッド３とからなり、その端縁が図示しない車体側取
付基板に固定され、又、前記パッド３の内面略中夫には
破断凹部４が形成されかつ表皮１のこの凹部４に対応す
る位置に図示の如く例えばナイフカットによる不連続（
あるいは図示しないが連続）なノツチ加工（いわゆる残
厚を有する力任）による破断部５′が形成されている。Conventionally, this type of cushion cover is as shown in Figure 1.
Consisting of a skin 1 and a pad 3 enclosing a core material 2 made of an iron plate, a resin plate, a wire mesh, etc., the edge thereof is fixed to a mounting board on the vehicle body side (not shown), and the inner surface of the pad 3 has a substantially central core. A fracture recess 4 is formed, and a discontinuity (for example, a knife cut) is made at a position corresponding to the recess 4 in the skin 1 as shown in the figure.
Alternatively, a broken portion 5' (not shown) is formed by continuous notching (so-called force cutting with residual thickness).
しかしてエアクッション基布作動展開時には表皮１の破
断部５′及びパッド３′の破断凹部４が破裂し、もって
所期の機能を果すものである。When the air cushion base fabric is activated and deployed, the broken portion 5' of the skin 1 and the broken concave portion 4 of the pad 3' burst, thereby achieving the intended function.
なお、上記破断部ピはノツチ加工により形成されるだけ
でなく、ナイフカントによりスリット加工しそのスリッ
トを別物のフィルムにより貼付閉塞し、あるいは穴を連
続配列して形成したものもある。Note that the above-mentioned broken part pins are not only formed by notching, but also by cutting slits by knife canting and closing the slits by pasting and closing the slits with another film, or by continuously arranging holes.
しかしながら表皮１の破断部ダは表皮１を成形したのち
後加工により形威しなければならず、またその形状によ
っては加工の位置決めおよびカット方向性を考慮する必
要があるため加工方法が難かしく、かつ製造バラツキの
原因となりコストアップと共に安定した性能の確保が困
難となっていた。However, the broken part of the skin 1 must be shaped by post-processing after the skin 1 is formed, and depending on the shape, it is necessary to consider the positioning and cutting direction of the process, making the processing method difficult. This also causes manufacturing variations, increases costs, and makes it difficult to ensure stable performance.
本考案はかかる従来の欠点を解消するためになされたも
ので、内側方に突出する溝を形成しその底部に一般部の
肉厚より薄い破断薄肉部を有する表皮と、芯材を内包し
たバンドとを一体に形成することによって、低廉かつ軽
量なりッション力バーを得るようにしたものである。The present invention was made to eliminate such conventional drawbacks, and includes a band that includes a skin that forms a groove that projects inward and has a broken thin-walled part at the bottom that is thinner than the thickness of the general part, and a core material. By integrally forming these, an inexpensive and lightweight cushioning force bar can be obtained.
以下本考案の一実施例を第２図、第３図ａ 、ｂを参照
して説明する。An embodiment of the present invention will be described below with reference to FIGS. 2 and 3a and 3b.
本考案においては、内側方に突出するＶ字状の溝１０を
形成しその底部に一般部の肉厚より薄い破断薄肉部５を
有する樹脂製の表皮１と、芯材２を内包したパッド３と
を一体に形成してクッションカバー６を得る。In the present invention, a resin skin 1 has a V-shaped groove 10 projecting inwardly and has a broken thin-walled part 5 thinner than the general part at the bottom thereof, and a pad 3 containing a core material 2. The cushion cover 6 is obtained by integrally forming the cushion cover 6 and the cushion cover 6.
ここで、表皮１の一般部とは前記溝部１０の部分を除い
た他の部分をいう。Here, the general portion of the skin 1 refers to the other portions excluding the groove portion 10.
なお、表皮１に破断薄肉部５を形成する方法としては、
真空成形法を採用すれば良い。Note that the method for forming the broken thin wall portion 5 on the skin 1 is as follows:
A vacuum forming method may be used.
これは樹脂製の表皮を真空成形するとき、その一部を溝
状にくぼませれば、その最深底部が薄肉になることを利
用したものである。This takes advantage of the fact that when a resin skin is vacuum-formed, if a part of it is recessed into a groove, the deepest part becomes thinner.
また、クッションカバー６の製造方法としては、破断薄
肉部５を有する前記表皮１の外形に合致する内側面を有
する所定の型に、該表皮１および芯材２を入れ、さらに
発泡剤を入れこれを発泡させパッド３を成形するもので
ある。The method for manufacturing the cushion cover 6 includes placing the skin 1 and the core material 2 into a predetermined mold having an inner surface that matches the outer shape of the skin 1 having the broken thin-walled portion 5, and then adding a foaming agent. The pad 3 is formed by foaming.
かくして表皮１とパッド３は一体化する。In this way, the epidermis 1 and the pad 3 are integrated.

の拘束緩衝機能を果すものである。FIG. 3a shows an air cushion device to which the cushion cover 6 obtained according to the present invention is applied, and 7 in the figure shows a vehicle body side mounting board to which the edge of the cushion cover 6 is fixed;
8 is a gas generator, and 9 is a cushion base fabric that expands when the gas generator 8 operates. When the gas generator 8 is activated in the event of a vehicle collision, a large amount of gas is generated within the cushion base fabric 9, causing the cushion to expand. The base fabric 9 expands due to the rise in its internal pressure, and the fractured thin section 5 of the cushion cover 6 and the fractured recess 4 formed in the pad 3 are fractured, the cushion cover 6 is expanded, and the cushion base fabric 9 further expands. It performs a predetermined restraint buffering function.
以上本考案によれば次に列挙する効果を奏する。As described above, according to the present invention, the following effects are achieved.
（１）表皮の破断薄肉部を、該表皮を真空成形により内
側方に突出形成する際同時に形成できるので、従来のよ
うに特別な後工程が不要となり従って工数が低減しかつ
生産性が向上してコストダウンが図れる。(1) Since the fractured thin part of the skin can be formed at the same time as the skin is formed to protrude inward by vacuum forming, there is no need for special post-processing as in the past, thus reducing the number of man-hours and improving productivity. This enables cost reduction.
（２）表皮の破断薄肉部を有する溝の深さ、温度条件、
引き具合条件などの真空成形条件を適宜選択することに
よって破断薄肉部の厚さを容易に変化させることができ
、もってクッションカバーの破断強度を任意に調整する
ことができる。(2) Depth and temperature conditions of the groove with the broken thin part of the epidermis,
By appropriately selecting vacuum forming conditions such as pulling conditions, the thickness of the thin-walled portion to be broken can be easily changed, and thereby the breaking strength of the cushion cover can be adjusted as desired.
（３）パッドに低密度発泡ウレタン等を用いて、車両衝
突時の緩衝機能をもたせても、カバー展開時表皮により
パッドの飛散を防止できるので非常に軽量なカバーが得
られる。(3) Even if the pad is made of low-density foamed urethane or the like to provide a cushioning function in the event of a vehicle collision, the outer skin can prevent the pad from scattering when the cover is deployed, making it possible to obtain a very lightweight cover.
（４）破断薄肉部が溝の底部すなわち外表面から奥まっ
た位置にあるので、手が触れにくく、したがって永年の
使用に対しても摩耗せず亀裂が生じる惧れがほとんどな
く作動時正常な機能を全うできる。(4) Since the fractured thin-walled part is located at the bottom of the groove, that is, at a position recessed from the outer surface, it is difficult to touch, so it does not wear out even after many years of use, and there is little risk of cracking, allowing it to function normally during operation. can be fulfilled.
