DETAILED DESCRIPTION OF THE INVENTION

[0022] The configuration of a waterproof covering material and a vehicle seat according to this embodiment will be described below with reference to the drawings. However, the embodiment described below is an example to facilitate understanding of the present invention and is not intended to limit the present invention. In other words, the present invention may be modified or improved without departing from the spirit thereof, and of course, the present invention also includes equivalents thereof.

[0023] In the following, a motorcycle seat will be taken as an example of a vehicle seat, and an example of its configuration will be described. However, the present invention is not limited to motorcycle seats, and may also be applied to seats for four-wheeled or three-wheeled vehicles mounted on ground-traveling vehicles with wheels such as automobiles and trains, or seats mounted on aircraft, ships, and other vehicles that travel other than on land.

[0024] In the following description, the "front-rear direction" refers to the front-rear direction of the motorcycle seat, which is the direction that coincides with the direction of travel of the motorcycle when it is traveling. The "seat width direction" refers to the width direction of the motorcycle seat, which is the direction that coincides with the left-right direction as seen by a rider seated on the seat. The "up-down direction" refers to the up-down direction of the motorcycle seat, which is the direction that coincides with the vertical direction when the motorcycle is traveling on a horizontal plane.

[0025] <Basic structure of motorcycle seats> The basic configuration of a motorcycle seat S will be described with reference to Fig. 1 to Fig. 3. Fig. 1 is a side view of a motorcycle M on which the motorcycle seat S is mounted. Fig. 2 is a bottom view of the motorcycle seat S, and Fig. 3 is a cross-sectional view of the motorcycle seat S taken along line III-III in Fig. 1.

[0026] 2 and 3, the motorcycle seat S includes a bottom plate 10, a cushion pad 11 placed on the bottom plate 10, and a cover material 12 that covers the cushion pad 11 and is joined to an end of the bottom plate. The cushion pad 11 corresponds to the cushion body of the present invention. 2, the edge of the covering material 12 and the edge 10a of the bottom plate 10 are joined using a tacker 33. Note that joining using the tacker 33 is just one example, and the bottom plate 10 and the covering material 12 may also be joined using sewing thread. Also, a cushion film 32 is provided between the cushion pad 11 and the covering material 12 to improve waterproofing (see FIG. 4). Note that if waterproofing is ensured by the covering material 12, the cushion film 32 may not be provided.

[0027] The covering material 12 has a laminated structure made up of multiple face materials. Specifically, it has a two-layer structure in which a water-absorbent base fabric 15 and a waterproof surface layer 16 are laminated in this order from the bottom. The base fabric 15 is made of a water-absorbent material having water-absorbing properties. Specifically, the base fabric 15 is made of a fabric made by knitting fibers, such as a tricot knit fabric. The surface layer 16 is made of a waterproof material. In this embodiment, polyvinyl chloride (PVC) is used as the waterproof material. Polyvinyl chloride is highly waterproof, inexpensive, and easy to process. By using polyvinyl chloride as the material for the surface layer 16, it is possible to maintain waterproofness while applying surface treatment to make it usable as synthetic leather. The material for the surface layer 16 may also be polyethylene or polyurethane.

[0028] Water penetration is suppressed by covering the cushion pad 11 with the skin material 12. However, at the joint between the bottom plate 10 and the skin material 12, particularly at the corners and inclined parts of the bottom plate 10, wrinkles occur in the skin material 12, creating gaps through which foreign matter such as rainwater and dust can enter.

[0029] 3, the motorcycle seat S of this embodiment is provided with an intrusion prevention portion 20 at the joint between the bottom plate 10 and the cover material 12, which prevents rainwater, dust, and other foreign matter from entering through the gap between the bottom plate 10 and the cover material 12. In the following description, rainwater, dust, and other foreign matter that enter through the gap may be simply referred to as foreign matter.

[0030] <Intrusion suppression section 20> The structure of the intrusion suppression portion 20 will be described with reference to Figures 4 and 5. Figure 4 is a partially enlarged view of part A in Figure 3. Figure 5 is a perspective view seen from arrow B in Figure 4, showing the intrusion suppression portion 20.

[0031] The intrusion prevention section 20 includes a discharge section 21 that discharges foreign matter that has entered the intrusion prevention section 20, and a guide section 22 that guides the foreign matter to the discharge section 21. By providing the discharge section 21 and having the guide section 22 guide foreign matter that has entered the intrusion prevention section 20 to the discharge section 21, the intrusion of foreign matter into the gap between the skin material 12 and the bottom plate 10 is prevented.

[0032] The intrusion suppression portion 20 is made of the same material as the covering material 12. By using the same material, it is possible to reduce manufacturing costs. Specifically, it is formed by laminating a water-absorbent base fabric 28 and a waterproof surface layer 29. The base fabric 28 is made of a fabric constructed by knitting fibers, and the surface layer 29 is made of polyvinyl chloride. The intrusion suppression portion 20 may be made of a material different from that of the covering material 12, and may be made of only polyvinyl chloride, for example.

[0033] The intrusion prevention portion 20 is formed as a long, narrow rectangular member, and is arranged along the edge of the cover material 12, as shown in Fig. 2. The intrusion prevention portion 20 is preferably provided in a portion of the motorcycle seat S where foreign objects may enter, such as a corner or an inclined portion of the bottom plate. One of the long sides of the intrusion prevention portion 20 is joined to the skin material 12 by sewing, and the other side is joined to the bottom plate 10 by a tacker 33.

[0034] 4, one of the long sides of the intrusion suppression part 20 is folded back, and the surface layer 16 of the intrusion suppression part 20 and the surface layer 16 of the skin material 12 are joined in an overlapping state. In addition, by folding back the side of the intrusion suppression part 20, a reservoir part 24 is formed that collects foreign matter that has invaded the intrusion suppression part 20.

[0035] By sewing the upholstery material 12 and the intrusion prevention portion 20 together, a through hole 23 through which a sewing thread 34 passes is formed at the joint. Foreign matter 35, such as rainwater, accumulated in the accumulation portion 24 is discharged through the through hole 23. In other words, the through hole 23 (sewn hole) formed by sewing functions as a discharge portion 21 that discharges foreign matter. Hereinafter, the discharge portion 21 formed by the through hole 23 is referred to as a first discharge portion 211. Note that the first discharge portion 211 is formed by the through hole 23, which is a sewn hole, but this is just one example, and the through hole 23 may be formed in the intrusion prevention portion 20 separately from the sewing hole. For example, the through hole 23 may be formed in the bottom of the accumulation portion 24, which will be described later, so that foreign matter 35 accumulated in the accumulation portion 24 is discharged.

[0036] The intrusion prevention section 20 also has a reservoir 24 that collects foreign matter 35 that has intruded through a gap 26 between the intrusion prevention section 20 and the bottom plate 10, and a guide section 25 that guides the foreign matter 35 to the reservoir 24. 4, guide portion 25 is disposed on the surface facing bottom plate 10, from gap 26, through which foreign matter 35 enters, to reservoir portion 24. Guide portion 25 is realized by absorbent base fabric 28 of intrusion prevention portion 20, and foreign matter 35 that enters through gap 26 is guided by base fabric 28 and moves to reservoir portion 24. Furthermore, reservoir 24 for collecting foreign matter 35 is realized by a curved portion formed by bending the side of intrusion suppression part 20. Since surface layer 29 of intrusion suppression part 20 is waterproof, foreign matter that has entered intrusion suppression part 20 can be collected in reservoir 24.

[0037] The intrusion suppression unit 20 also has a first guide portion 221 as the guide portion 22 that guides the foreign matter 35 from the reservoir portion 24 to the first discharge portion 211. The first guide portion 221 is realized by the absorbent base fabric 28 of the intrusion suppression unit 20. The foreign matter 35 that has permeated the base fabric 28 moves to the first discharge portion 211 and is discharged from the first discharge portion 211. In other words, the guide portion 22, including the first guide portion 221 and the second guide portion 222 described below, is composed of a water-absorbent material.

[0038] 2, the intrusion prevention portion 20 is provided so as to extend along the end portion 10a of the bottom plate 10. The intrusion prevention portion 20 has a second guide portion 222 that guides the foreign matter 35 in the direction in which the intrusion prevention portion extends.

[0039] 5, the intrusion prevention unit 20 has an opening 27 at the end 20b in the extending direction (end in the longitudinal direction), and the foreign matter 35 guided by the second guide unit 222 may be discharged from the opening 27. In other words, the opening 27 of the intrusion prevention unit 20 constitutes a second discharge unit 212 that discharges the foreign matter 35.

[0040] As described above, the intrusion suppression portion 20 has a folded portion 20a formed by folding back the side portion 20c, which is the long side. As shown in FIG. 4 , the cover material 12 has an overlapping portion 12a that overlaps with the intrusion suppression portion 20, and the folded portion 20a is fixed along the overlapping portion 12a. In this embodiment, the folded portion 20a is fixed to the overlapping portion 12a by sewing, but it may also be fixed by adhesive. In this case, a through hole 23 that becomes the first discharge portion 211 is separately formed in the folded portion 20a. Alternatively, the folded portion 20a may be fixed to the cover material 12 by adhesive and sewing. Alternatively, the folded portion 20a may be fixed to the cover material 12 by a tacker 33.

[0041] <Corner portion 14 of bottom plate 10> The corner portion 14 of the bottom plate 10 will be described with reference to Figures 2, 5, and 6. Figure 6 is a partially enlarged view of part C in Figure 2, showing the state immediately before the covering material 12 is fixed to the bottom plate 10 by the tacker 33.

[0042] The corners 14 of the bottom plate should be appropriately protected because they may be damaged in a collision. In this embodiment, the bottom plate 10 is further provided with a protective skin 30 in addition to the skin 12 to protect the corners 14. The protective skin 30 is fixed to the corners 14 of the bottom plate 10 with a tacker 33.

[0043] 2 and 5, the end 30a of the protective skin 30 is arranged to overlap the end 20b of the intrusion suppression portion 20, and the protective skin 30 is fixed to the skin 12 and the intrusion suppression portion 20. By providing the protective skin 30 in this manner, the corner portion 14 is protected while preventing foreign matter from intruding through the corner portion 14.

[0044] 6, a protective member 31 is provided on the back surface of the corner portion 14 of the bottom plate 10 to protect the corner portion 14. The protective member 31 is preferably waterproof. The protective member 31 is, for example, a foam sealing material such as Eptsealer (registered trademark). The protective member 31 is adhered and fixed to the corner portion 14 with a rubber-based adhesive or an acrylic-based adhesive.

[0045] The protective member 31 is not particularly limited as long as it is waterproof and can seal holes and gaps, and examples thereof include a sheet-like substrate made of a rubber-based material or a synthetic resin-based material coated with an adhesive. Examples of rubber-based materials include butyl rubber and silicone rubber. Examples of synthetic resin-based materials include polyethylene and EVA (ethylene-vinyl acetate copolymer resin). By providing the protective member 31, the corner portion 14 is protected and foreign matter is prevented from entering through the corner portion 14.

[0046] As described above, the motorcycle seat S is provided with the cushion film 32 that protects the surface of the cushion pad 11 and the back surface of the end 10a of the bottom plate 10, and this cushion film 32 may also be attached so as to cover the protective member 31 at the corner portion 14. Covering the protective member 31 with the cushion film 32 can prevent foreign matter 35, such as rainwater, from seeping into the protective member. The cushion film 32 corresponds to the film of the present invention.

[0047] Furthermore, the protective member 31 and the cushion film 32 covering the protective member 31 may be fastened to the corners 14 of the bottom plate 10 with a tack 33. This allows the protective member 31 and the cushion film 32 to be attached to the bottom plate 10 more firmly, thereby preventing the intrusion of foreign matter. The protective member 31 may be provided at a position overlapping the intrusion prevention portion 20 or the protective skin 30, or the protective member 31 and the intrusion prevention portion 20 may overlap and be fastened to the bottom plate 10 with a tack 33. The protective member 31 and the protective skin 30 may overlap and be fastened to the bottom plate 10 with a tack 33.

[0048] At the corner portion 14, the end portion of the skin material 12 is further arranged to overlap the protective member 31 and the cushion film 32. As shown in Fig. 6, the skin material 12 has a plurality of slits 13 formed in the portion where it joins with the corner portion 14 of the bottom plate 10. By forming the slits 13, the end portion of the skin material 12 can be fitted to the shape of the corner portion 14, and the end portion of the skin material 12 can be attached to the corner portion 14 while suppressing the occurrence of wrinkles. The slits 13 are not limited to being provided at the corners 14, but may also be provided at the curved portions of the end portions 10a of the bottom plate 10.

[0049] The intrusion prevention portion 20 and the protective skin material 30 are provided in a position facing the slit 13 formed in the skin material 12. In other words, the intrusion prevention portion 20 and the protective skin material 30 are attached so as to cover the slit 13. By covering the slit 13 with the intrusion prevention portion 20 and the protective skin material 30, it is possible to prevent foreign matter from entering through the slit 13.
