くすることが好ましく、一方シート側面はシート
自体の型くずれを防止するためある程度剛性に優
れていることが好ましい。 Incidentally, seats for motorcycles are required to have both riding comfort and durability. That is, since the upper surface of the seat is the part on which the occupant directly sits, it is preferable that the seat has a soft feel, while the side surfaces of the seat preferably have a certain degree of rigidity to prevent the seat itself from deforming.
このようにシート上面とシート側面とは異なる
特性が要求されるため、従来から各種のシートが
提案されている。 Since the upper surface of the sheet and the side surface of the sheet require different characteristics, various sheets have been proposed in the past.
例えば実公昭58−33018号に開示されるシート
はウレタンフオームと樹脂製表皮との間にフエル

表皮のうちシート上面となる部分にシボ模様を形
成し、シート上面の滑りを防ぐようにしたもので
ある。 For example, the seat disclosed in Utility Model Publication No. 58-33018 has felt interposed between the urethane foam and the resin skin to improve ride comfort and prevent the urethane foam from being locally compressed and deformed. , and a sheet disclosed in JP-A-58-185382 has a textured pattern formed on the upper surface of the resin skin covering the urethane foam to prevent the upper surface of the sheet from slipping.
（考案が解決しようとする問題点）
上述した如く従来にあつてはシート自体の形状
のみならず素材自体にも各種の工夫を凝らし、乗
心地性と耐久性の双方を満足するようにしている
が、充分な結果は得られず且つコスト的にも不利
がある。(Problems that the invention aims to solve) As mentioned above, in the past, various improvements have been made not only to the shape of the seat itself but also to the material itself, in order to satisfy both comfort and durability. However, sufficient results cannot be obtained and there are disadvantages in terms of cost.
（問題点を解決するための手段）
上記問題点を解決すべく本考案は、シートのク
ツシヨン材を合成樹脂製表皮で被覆するととも
に、該表皮のうちシート上面を覆う表皮を多孔質
層のみからなるものとし、シート側面を覆う表皮
を外側が硬質層からなるものとした。(Means for Solving the Problems) In order to solve the above problems, the present invention covers the cushion material of the seat with a synthetic resin skin, and the skin that covers the top surface of the seat is made of only a porous layer. The outer skin covering the side surfaces of the seat was made of a hard layer.
（実施例）
以下に本考案の実施例を添付図面に基いて説明
する。(Example) An example of the present invention will be described below based on the accompanying drawings.

いる。 FIG. 1 is an overall side view of a motorcycle to which the seat according to the present invention is applied. The motorcycle 1 has a main pipe 3 extending rearward and downward from the upper end of a head pipe 2, and a fuel tank 4 on the main pipe 3. A seat 6 is installed on a seat rail 5 extending rearward from the middle of the main pipe 3. This sheet 6 is shown in the overall perspective view of FIG.
As shown in FIG. 3, which is a sectional view taken along the line A-A in the figure, the lower surface of the cushion material 7 made of urethane foam is supported by a resin bottom plate 8, and the surface of the cushion material 7 is made of synthetic resin such as polyvinyl chloride. It is covered with the epidermis 9 of.
ところで、表皮９はシート６の上面を覆う表皮
１０とシート６の側面を覆う表皮１１とをウエル
ダー溶着してなり、第４図の拡大図に示すように
表皮１０は柔軟性に優れた多孔質層１０ａのみで
構成し、表皮１１は内側を多孔質層１１ａ、外側
を硬質層１１ｂとしている。 Incidentally, the skin 9 is formed by welding together a skin 10 that covers the top surface of the sheet 6 and a skin 11 that covers the side surfaces of the sheet 6. As shown in the enlarged view of FIG. 4, the skin 10 is made of a porous material with excellent flexibility. It is composed of only a layer 10a, and the skin 11 has a porous layer 11a on the inside and a hard layer 11b on the outside.
ここで、表皮１１を形成するには気体混入法を
用いる。具体的にはポリ塩化ビニルペーストに低

造を持たない硬質層１１ｂを形成した表皮１１を
得る。 Here, a gas mixing method is used to form the skin 11. Specifically, polyvinyl chloride paste is melted with carbon dioxide or other gas at low temperature, stirred at high speed to disperse the gas in the paste, and then applied to a mold of a predetermined shape and heat-treated to form a gel. A porous layer 11a having a stable cell structure is formed by solidification, and a skin 11 is obtained in which a hard layer 11b having no cell structure is formed in the portion in contact with the mold.
一方、表皮１０を得るには上記と同様にして形
成した表皮のうち、硬質層の部分を剥すことで得
る。 On the other hand, the epidermis 10 is obtained by peeling off the hard layer of the epidermis formed in the same manner as above.
そして、上記の如くして得られた表皮１０及び
１１を所定形状にトリミングし、クツシヨン材７
表面をこれら表皮１０，１１にて覆うとともに、
表皮１０，１１の端縁部を前記した如くウエルダ

いものが得られる。 Then, the skins 10 and 11 obtained as described above are trimmed into a predetermined shape, and the cushion material 7 is
While covering the surface with these epidermis 10, 11,
By welding the edge portions of the skins 10 and 11 as described above, the skin 9 as a whole can be obtained without any lumps.
尚、図示例にあつては、表皮１０と表皮１１を
溶着する部分をシートのアール部の略下端位置と

アール部は多孔質層１０ａとし、クツシヨン性の
向上を図つているが、シートの側面全体を硬質層
１１ｂとし、表皮１０はシートの上面のみを覆う
ようにしてもよい。 In the illustrated example, the part where the skin 10 and the skin 11 are welded is located at the approximate lower end of the rounded part of the seat, and the part where the occupant's feet come into contact is the hard layer 11b.
Although the rounded portion is made of a porous layer 10a to improve cushioning properties, the entire side surface of the sheet may be made of a hard layer 11b, and the skin 10 may cover only the top surface of the sheet.
また、第５図は別実施例を示すものであり、こ
の実施例にあつては表皮１０と表皮１１を内側に
折り返してウエルダー溶着し、表皮１０は多孔質

形成している。このようにしてもシートの乗心地
性と耐久性は向上する。 Further, FIG. 5 shows another embodiment, in which the skin 10 and the skin 11 are folded inward and welded together, the skin 10 is only a porous layer 10a, and the skin 11 is a hard layer. It is formed of only the layer 11b. This also improves the riding comfort and durability of the seat.
