【発明の詳細な説明】
本発明は、シートのクツシヨンに関するもので
ある。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a seat cushion.
一般に車輌等のシートクツシヨンにおいては、
着座する人の安定する姿勢位置と、且つ快適な座
り心地を確保するため、その座着部、即ち中央部
分には適当な凹状の窪み部が形成されている。 In general, seat cushions for vehicles, etc.
In order to ensure a stable posture and a comfortable sitting position for the person sitting on the seat, a suitable concave recess is formed in the seat portion, that is, the central portion.
即ち、予め窪み部を成形したクツシヨン材に表
層材が被覆され、しかる後所定部所において両者
を結合したものである。 That is, a cushion material in which recesses have been formed in advance is coated with a surface layer material, and then the two are bonded at predetermined locations.
従来、この結合には、ワイヤ、掛金等が用いら
れたが、製作及び使用効果等の面で不具合な欠陥
があるため、近年これを高周波溶着手段で前記表
層材をクツシヨンに対し溶着融接着せしめる技術
が発達してきた。 Conventionally, wires, latches, etc. have been used for this connection, but since they have some defects in terms of manufacturing and usability, in recent years these have been replaced by high-frequency welding means to weld and fuse the surface material to the cushion. Technology has developed.
この技術では、クツシヨン材に被覆される表層
材を、高周波加熱溶着が可能な素材で作り、クツ
シヨン材と共に高周波ウエルダに入れ、加圧印加
してこれを溶着せしめたものである。 In this technique, the surface material covering the cushion material is made of a material that can be welded by high frequency heat, and the material is placed in a high frequency welder together with the cushion material, and pressure is applied to weld the material.
しかし、クツシヨン材は第１〜３図をみて分る
ように、その厚さが通常一定していないため、前

方が該部所間での均等性を欠き、溶着強度が部所
的に相異する欠陥があつた。この現象は、強度、
耐久性面での問題とされていた。 However, as can be seen from Figures 1 to 3, the thickness of the cushion material is usually not constant, so when pressed with the electrode of the high-frequency welder, there are differences in the thickness depending on the pressed area. There was a defect that the pressure was not applied uniformly between the parts, and the welding strength differed from part to part. This phenomenon is caused by intensity,
There were concerns about durability.
本発明では、上記不具合な問題点の解消を計つ
たものである。即ち、クツシヨン材の成形時、該
クツシヨン材に前記電極が挿入される溝を形成せ
しめたものである。 The present invention aims to solve the above-mentioned problems. That is, when the cushion material is molded, a groove into which the electrode is inserted is formed in the cushion material.
而して、好ましくないこの溝は、前記クツシヨ
ン材の上面からほぼ一定の肉厚が残される深さに
設定される。つまり、溝の深さとクツシヨン材上
面との被押圧部位における残された厚さとは比例
するものである。 Therefore, this undesirable groove is set to a depth such that a substantially constant thickness remains from the upper surface of the cushion material. In other words, the depth of the groove and the thickness remaining at the pressed portion of the upper surface of the cushion material are proportional.
従つて、クツシヨン材はその押圧部位の母材厚
如何に係わらず、肉厚薄く、更には、一定した厚

られた肉厚差による押圧時の肉ずれ現象が出ない

された溶着結合力が附与される。これにより、製
作面では作業性に優れ、耐久性あり且つ、商品と
して外観上でも優美に統一されたシートクツシヨ
ンの製作に役立つ効果を有する。 Therefore, the cushion material has a thin wall thickness regardless of the thickness of the base material at the pressed area, and furthermore, it is welded to the surface material at a constant thickness, which eliminates the conventional difference in wall thickness. Since there is no slippage phenomenon during pressing, a uniform welding bonding force is applied without shifting the welding position. This has the advantage of being useful in producing seat cushions that are excellent in workability, durable, and elegantly unified in appearance as a product.

A series of grooves are provided. As shown in FIGS. 5 and 6, the grooves 1a, 1b, 1c, etc. have a thickness t of the base material left from the groove bottom to the surface of the cushion material 1.
(generally about 20 to 30 mm), but even if the base material thickness changes t 1 to t 4 at the part where the groove is provided, the groove changes from the bottom surface so that it is almost constant in any part. It's getting deeper.

The groove part (only part 1a is shown in the figure) is fitted into the electrode part 2a of the high-frequency welder lower mold 2, and the surface material 3
After positioning, pressure is applied with the upper die 2' of the welder to weld the two together as shown in FIG. Note that 4 indicates a sheet material embedded in the cushion material 1 and capable of high frequency welding.
