極的な工夫はなされていない。<Background of the Invention> In general, various contrivances have been made on seats of vehicles and other transport equipment to provide comfortable sitting comfort for occupants and the like. By the way, even in the case of transportation equipment, snowmobiles, motor boats, motorcycles, etc., have severe irregularities in the running route itself, and there are various performances and functions required for seats. That is, snowmobiles and motorcycles, especially motorcycles suitable for traveling on unpaved roads, etc., are extremely intensely pushed up from the bottom, while the rider uses the entire body including the waist when traveling, for example, changes the sitting position I always try to run a stable run. For this reason, for example, in terms of shock absorption only, it is only necessary to make the thickness of the foamed resin, synthetic rubber, foamed synthetic rubber, etc., which is the material of the seat, sufficient, to perform shock absorption. In the case of motocross running in which the vehicle body is tilted greatly during cornering and various impacts are received from the road during the cornering, the seat itself needs to have a certain degree of rigidity along with the so-called cushion function The design is such that it is easy to take a riding form that can hold down the vehicle body. Also, in a trial competition where the motorcycle passes through a section with obstacles without putting on feet, the rider lifts his hips during the section and balances, so seats are almost unnecessary. However, considering the movement between sections and running in the city, even though it is a motorcycle for trial, the seat also needs to have appropriate cushioning performance. As described above, depending on the model, there are various and complex performance requirements for the seats. Conventionally, to meet such demands, measures such as combining foam resins having different hardnesses at best are used. But no further effort has been made.

はいわゆる座屈応力としてこれが作用する。First, FIG. 2 shows the most basic embodiment of the present invention, in which a gel stock solution g is injected into a foamed resin base material B at one point inside the base material, and is cured and gelled as it is. It was made. And the silicone gel G
Is set according to the degree of curing of the silicone gel G, and can be selected as appropriate. To configure the seat S of applying this, for example, with respect to the seat base S B made of a synthetic resin plate having a sufficient rigidity, molding the seat material for 1 to appropriate shape, their synthetic resin leather etc. and configure the mounting by the mounting body S C consisting. When the seat S is constituted by the seat material 1 as shown in FIG. 2 (a), a plurality of substantially spherical vibration-absorbing regions 2 are formed in the seat material 1 which plays a role of cushioning. It is formed. In FIG. 3, after the gel stock solution g is injected in the same manner as in FIG. 2, mechanical stress is applied before curing, compression is performed, and then the pressure is released.
Are hardened in a dispersed state.
A seat S to which this is applied is configured in a state where the vibration absorption enhanced areas 2 in the seat material 1 that directly plays a cushioning function are relatively dispersed. Further, the one shown in FIG.
It consists of the same technical idea as the embodiment shown in the figure,
The direction in which the mechanical stress is applied is changed from the compression direction to the torsion direction. The seat S to which this is applied is formed in a state in which the silicone gel G is dispersed in an irregular shape, and the vibration-absorbing enhanced area 2 is dispersed in the seat material 1 that has a cushioning effect on the seat S. In the embodiment shown in FIG. 5, the mechanical pressure is used as the external stress in the embodiment shown in FIGS. 3 and 4, but the pressure of the air in the sealed chamber is varied. Specifically, the foamed resin base material B into which the gel stock solution g is injected is put into the decompression chamber 5, and then the pressure in the decompression chamber 5 is reduced. When the gel stock solution g is dispersed, the foamed resin base material B is taken out, and the gel is removed. The stock solution g is hardened and gelled to form the vibration absorption enhanced region 2. The seat S to which such a seat material 1 is applied is in a state in which the silicone gel G is partly separated as shown in FIG. 5 (d). In each of the above embodiments, the case where the gel stock solution g is injected at one point inside the foamed resin base material B is handled. However, the gel stock solution g is injected into a plurality of locations inside the foamed resin base material B. Can also. The embodiment shown in FIGS. 6 to 8 described below incorporates such a technical idea. In FIG. 6, the injection body 8 in which a number of nozzle-shaped injection needles 7 are arranged close to the foamed resin base material B, and the injection needles 7 reach a predetermined position inside the foamed resin base material B. At this point, one or a few drops of the gel stock solution g are injected and then cured to form a sphere after gelation. In the illustrated embodiment, the injection needles 7 of the injection body 8 have different lengths arranged in a matrix.
A seat S to which this is applied is formed in a state where a number of silicone gels G having a relatively small particle size are dispersed in a foamed resin base material B inside. FIG. 7 shows the embodiment of FIG. 6 in which the injection needle 7 is inserted to a predetermined position inside the foamed resin base material B and the gel stock solution g is continuously injected, and the injection needle 7 is gradually moved. Then, the vibration absorption enhanced area 2 is constituted by a large number of needle-bar-shaped silicone gels G. In FIG. 7 (b), the needle bar-shaped silicone gel G is provided three-dimensionally in the X, Y, and Z-axis directions to constitute the vibration absorption enhanced region 2. As shown in FIG. 7 (c), a thin seat-bar-shaped silicone gel G is three-dimensionally arranged in the X, Y and Z axis directions in a foamed resin base material B for absorbing vibration as shown in FIG. 7 (c). The vibration absorption enhancement regions 2 are formed evenly.
Such a technical idea can be applied to an embodiment shown in FIG. 8 described later. Needle-bar-shaped silicone gel G can of course also be provided on the X, Y, and Z-axis directions, and on a plurality of axes having different directions, for example, skewed. Further, what is shown in FIG. 8 is an embodiment in which the gel stock solution g is intermittently injected instead of being continuously injected in the embodiment shown in FIG. A seat S to which this structure is applied is similarly configured such that a large number of dot-shaped or somewhat long needle-bar shaped vibration absorption enhanced areas 2 are formed therein. In addition, the above-mentioned respective methods of injecting the gel stock solution g are used not only for the purpose of improving the properties of the entire foamed resin base material B, but also for the embodiment of the motorcycle MC for motocross competition shown in FIG. Thus, it can also be used for the purpose of improving the properties of only a specific portion of the foamed resin base material B. For example, it is also possible to improve the properties by injecting the gel stock solution g into places where impacts, loads and the like are intensively applied, or into places where the structure is absolutely weak and the strength is to be increased. For example, in order to improve maneuverability when traveling at high speed on an unpaved road or the like where the road surface impact is severe as in this embodiment, in the case of a type in which the front end of the seat S covers up to the upper surface of the fuel tank T, Is relatively thin and the buffer performance is not always sufficient.
May be injected. In each of the above embodiments, the foamed resin base material B was not subjected to any processing before injection of the gel stock solution g. For example, FIGS. 10 (a) and 10 (b)
(C) As shown in FIG.
Prior to the injection, the injection slit 10 may be provided as a pre-process, and the injection needle 7 may be inserted to form the vibration absorption enhanced region 2. The injection slit 10 has a minimum gap c necessary for inserting the injection needle 7 as the injection body 8 or the injection chute 12 as another injection body 8 described later.
It is preferable that the gap c is slightly smaller than the outer diameter d of the injection needle or the thickness t of the injection chute (actually, the gap c is too small to be seen by the naked eye due to the resilience of the foamed resin base material B). It is preferable that the insertion needle 7 or the injection chute 12 be inserted so that the gap c of the injection chute 12 is expanded. As shown in FIGS. 10 (a) and 10 (i), as an example, the injection slit 10 extends from one surface (upper surface in the drawing) to the opposite surface (bottom surface in the drawing) with respect to the cubic foamed resin base material B. The slit space is formed so as to be flat. Then, the injection needle 7 is inserted into the injection slit 10 formed in this way, and when reaching a predetermined position, the injection of the undiluted gel solution g is started, and the injection needle 7 is pulled up to the upper surface while reciprocating right and left. Thereby, the vibration absorption enhancement region 2 including the zigzag gel trajectory can be formed. FIG. 10 (b) shows the injection slit 10 in the embodiment of FIGS. 10 (a) (i) formed so that the slit space becomes cylindrical. In forming the vibration absorption enhancement region 2 for such an injection slit 10, a spiral gel is drawn by pulling up the injection needle 7 inserted to a predetermined position in an arc along the wall surface of the injection slit 10. It may have a trajectory. Further, FIG. 10 (c) shows a spatula-shaped injection chute 12 having a thickness t smaller than that in the width direction with respect to the injection slit 10 having the same shape as that of FIG. 10 (a) (i). The vibration absorption enhancement region 2 is formed by inserting the gel stock solution g over almost the entire slit space of the injection slit 10. FIG. 10 (a) and FIG. 10 (ii) show the seats S to which these are applied in correspondence with each other. As shown in FIGS. Or the one in which the absorption-enhancing region 2 is spirally formed inside as shown in FIGS. 10 (b) and (ii), or the one in which the absorption-enhanced region 2 is formed as a flat plate as shown in FIGS. Etc. are applied. In the case of the embodiment shown in FIG. 10 (c) having a flat plate shape, this acts on the vibration absorption enhanced area 2 as a so-called buckling stress.

る場合もある。In the above-described embodiment, the vibration-absorbing reinforced region 2 is partially formed in the foamed resin base material B. For example, in the embodiment shown in FIG. 3 and the like, the injection amount of the gel stock solution g and how to apply external stress are determined. In some cases, almost the entire region of the foamed resin base material B becomes the vibration absorption enhanced region 2.

ていて特に目立つというほどのものでもない。<< Effects of the Invention >> As described above, since the vibration-absorbing reinforced region 2 is formed inside the foamed resin base material B, the present invention is far more resistant than the conventional seat material 1 made of foamed resin alone. It is possible to provide a seat S that is excellent in impact and has high vibration absorption. In particular, the present invention is more suitable for constructing a seat or the like of a motorcycle for a snowmobile, a motocross competition, a trial competition, or the like, in which a demand for shock absorbing performance or vibration absorbing performance is intense. In addition, since such a snowmobile and a motorcycle for motocross competition are played and used regardless of the weather such as clear rain, snowfall, etc., the seat material 1 itself is compounded with the silicone gel G, Water repellency is generated, and in this respect, weather resistance is also exhibited. Further, since the silicone gel G has low temperature dependency, the vibration absorption performance does not change even in an extremely cold environment to a high heat environment, and stable performance is exhibited. Furthermore, when a compressive load is applied to the seat S due to the presence of the vibration absorption enhanced region 2 made of the silicone gel G, the deformation rate progressively decreases with an increase in the load, so that a so-called drop can be prevented. In the case where the vibration absorption enhanced area 2 is formed inside the foamed resin base material B, the original area 3
Is not different from the conventional foamed resin alone, and can be used in the same manner as the conventional product. Specifically, since the silicone gel G constituting the vibration absorption enhanced area 2 does not flow out to the surface layer of the seat sheet material 1, various adhesives can be applied without stickiness. In addition, since the vibration-absorbing enhanced area 2 can be formed as a post-process on the foamed resin base material B after the molding process as a finished product, existing equipment can be used and can be used in combination with a conventional molding machine. Furthermore, when the method of injecting with the injecting needle 7 is used to form the vibration absorption enhanced region 2, the appearance of the seat material 1 is not significantly impaired. Also in the embodiment in which the injection slit 10 is provided, the cut is actually almost closed and not particularly noticeable.
