Summary of the Invention

Problems to be Solved by the Invention

[0004] However, Patent Document 1 does not disclose a structure for appropriately supporting the head of an occupant, and improvement in the supportability and safety during seating including the head has been demanded. In addition, vehicles such as buggies, side-by-side vehicles, and golf carts used outdoors may have their seats directly exposed to rain, wind, and mud. Therefore, improvement in waterproofness, water repellency, drainage, ease of maintenance when soiled, etc. has been demanded.

[0005] The present invention has been made in view of the above problems, and an object thereof is to provide a vehicle seat that improves the supportability and safety of the head during seating by making it adjustable to appropriately support the head of an occupant. Another object is to improve the waterproofness, water repellency, drainage, ease of maintenance when soiled, etc. of the seat.

Means for Solving the Problem

[0006] According to the vehicle seat of the present invention, the above problem is solved by providing a seat back that supports the back of an occupant, a headrest provided above the seat back that supports the head of the occupant, and at the lower end of the headrest, a ratchet mechanism that rotatably connects the headrest to the seat back and fixes the headrest at a predetermined angle. , a backrest member covering the back surface of the seat back and the back surface of the headrest is provided. The headrest is disposed in front of the backrest member and has a headrest support member that covers the back surface of the headrest and supports the headrest. The headrest support member is connected to the backrest member by a connecting member extending forward from the backrest member at the connection portion between the seat back and the headrest. A concave portion that is recessed forward is formed in the backrest member at the connection portion between the headrest and the seat back. The connecting member extends forward from the bottom of the concave portion This solves the problem. By providing a vehicle seat with a ratchet mechanism that rotatably connects the headrest to the seat back and fixes it at a predetermined angle, it becomes possible to appropriately support the head of the occupant, improving the supportability and safety of the head during seating. In addition, since the headrest has a headrest support member, it is possible to suppress a decrease in the rigidity of the headrest. In addition, since the headrest is connected to the backrest member by a connecting member extending forward from the backrest member, the rigidity of the connection portion can be increased. In addition, since a concave portion is formed at the connection portion, the rigidity of the backrest member is increased, and since the connecting member extends forward from the bottom of the concave portion, the headrest can be supported more stably.

[0008] Further, in the above vehicle seat, the headrest preferably consists of a headrest pad and a headrest support member, and the headrest Pad is attached to the seat back so as to rotate integrally with the headrest support member. By rotating the headrest pad and the headrest support member integrally su it is possible to rotate the headrest while maintaining its rigidity.

[0009] Further, in the above vehicle seat, it is preferable that a gap is formed between the back member and the headrest support member. By forming a gap between the back member and the headrest support member, it is possible to suppress the generation of abnormal noise caused by the contact between the back member and the headrest support member.

[0011] Further, in the above vehicle seat, the ratchet mechanism is preferably provided at the center of the lower surface of the headrest in the front-rear direction of the seat. By providing the ratchet mechanism at the center of the lower surface of the headrest in the front-rear direction of the seat, the headrest can be rotated in the front-rear direction in a well-balanced manner.

[0012] Further, in the above-mentioned vehicle seat, the ratchet mechanism may be provided at the center of the lower surface of the headrest in the seat width direction. By providing the ratchet mechanism at the center of the lower surface of the headrest in the seat width direction, the headrest can be supported and rotated in a well-balanced manner.

[0013] Further, in the above-mentioned vehicle seat, the headrest support member may have a shaft support portion that protrudes forward at the lower end portion and supports the rotation shaft of the ratchet mechanism. By having a shaft support portion that protrudes forward at the lower end of the headrest support member and supports the rotation shaft of the ratchet mechanism, the attachment of the ratchet mechanism becomes easy and the assemblability of the headrest is improved.

[0014] Further, in the above-mentioned vehicle seat, an inclined portion that inclines downward from a connection portion connecting to the headrest in the front-rear direction of the seat may be provided on the upper surface of the seat back. By providing the inclined portion on the upper surface of the seat back, interference between the headrest and the seat back during headrest rotation can be avoided.

[0016] Further, in the above-mentioned vehicle seat, a bent portion formed along the shape of the concave portion may be provided at a portion of the headrest support member facing the concave portion of the back member. By providing the bent portion on the headrest support member, contact with the back member is avoided and the generation of abnormal noises and the like can be suppressed.

Advantages of the Invention

[0017] According to the present invention, the headrest is rotatably connected to the seat back and is provided with a ratchet mechanism for fixing at a predetermined angle, so that it is possible to appropriately support the head of the occupant and improve the supportability and safety of the head during seating. In addition, since the headrest has a headrest support member, it is possible to suppress a decrease in the rigidity of the headrest. Further, by rotating the headrest pad and the headrest support member integrally, the headrest can be rotated while maintaining the rigidity of the headrest. In addition, by forming a gap between the back member and the headrest support member, it is possible to suppress the generation of abnormal noise due to the contact between the back member and the headrest support member. Further, by connecting the headrest to the back member by a connecting member extending forward from the back member, the rigidity of the connection portion can be increased. In addition, since the ratchet mechanism is provided at the center of the lower surface of the headrest in the front-rear direction of the seat, the headrest can be rotated in the front-rear direction in a well-balanced manner. In addition, by having a shaft support portion that protrudes forward at the lower end of the headrest support member and supports the rotation shaft of the ratchet mechanism, the attachment of the ratchet mechanism becomes easy and the assemblability of the headrest is improved. In addition, by having an inclined portion on the upper surface of the seat back, it is possible to avoid interference between the headrest and the seat back when the headrest rotates. In addition, by forming a concave portion in the connection portion, the rigidity of the back member is increased, and since the connecting member extends forward from the bottom of the concave portion, the headrest can be supported more stably. In addition, by providing a bent portion on the headrest support member, contact with the back member is avoided and the generation of abnormal noise and the like can be suppressed.

Embodiments for Carrying Out the Invention

[0019] <<First Embodiment>> Hereinafter, the configuration of the waterproof skin material and the vehicle seat according to the embodiments of the present invention will be described with reference to the drawings. However, the embodiments described below are examples for facilitating the understanding of the present invention and do not limit the present invention. That is, the present invention can be changed and improved without departing from its gist, and it goes without saying that the present invention includes equivalents thereof.

[0020] In the following, as an example of a vehicle seat, a vehicle seat such as a four-wheel buggy mainly used outdoors will be cited, and its configuration example will be described. However, the present invention is not limited to the vehicle seat used for a four-wheel buggy, and may be a vehicle seat mounted on a ground vehicle having wheels such as an automobile or a railway, or a seat mounted on an aircraft or a ship moving other than on the ground.

[0021] In the following description, the "front-rear direction" is the front-rear direction of the vehicle seat and coincides with the traveling direction of the vehicle when it is running. The "seat width direction" is the width direction of the vehicle seat and coincides with the left-right direction as seen from the occupant sitting on the seat. The "vertical direction" is the vertical direction of the vehicle seat and coincides with the vertical direction when the vehicle is running on a horizontal plane.

[0022] <Basic Configuration of Vehicle Seat S1> The basic configuration of the vehicle seat (hereinafter referred to as vehicle seat S1) according to this embodiment will be described with reference to FIG. 1. FIG. 1 is a perspective view of the vehicle seat S1. For some parts of the vehicle seat S1 in FIG. 1, for convenience of illustration, the skin materials 12, 22, and 32 are removed and shown in a configuration without them.

[0023] The vehicle seat S1 is a seat placed on the vehicle body floor and on which the vehicle occupant (seated person) sits. In this embodiment, the vehicle seat S1 is used as a front seat corresponding to the front seat of the vehicle. However, it is not limited to this. The vehicle seat S1 can also be used as a rear seat, and can also be used as a middle seat in the second row or a rear seat in the third row in a vehicle equipped with three rows of seats in the front-rear direction.

[0024] As shown in FIG. 1, the vehicle seat S1 mainly includes a seat back 1 that supports the back of the seated person, a seat cushion 2 that supports the buttocks of the seated person, and a headrest 3 arranged above the seat back 1 that supports the head of the seated person. The seat back 1 and the seat cushion 2 are connected by a frame such as a round pipe.

[0025] The seat back 1 is composed of a bottom plate 10 (see FIG. 4) that is a back material, a back pad 11 that is a cushion material arranged on the bottom plate 10, and a skin material 12 that covers the back pad 11. Also, the seat cushion 2 is composed of a bottom plate (not shown) and a cushion pad 21 that is a cushion material placed on the bottom plate, and a skin material 22 that covers the cushion pad 21.

[0026] The headrest 3 is composed of a headrest support member 30 (see FIG. 3), a headrest pad 31 that is a cushion material arranged on the headrest support member 30, and a skin material 32 that covers the headrest pad 31.

[0027] The bottom plate 10 and the headrest support member 30 are plates made of resin or metal. The back pad 11, the cushion pad 21, and the headrest pad 31 are, for example, urethane pads formed by foam molding using a urethane foaming agent.

[0028] The skin materials 12, 22, and 32 have a laminated structure formed by laminating a plurality of facing materials. The layers constituting the skin materials 12, 22, and 32 are composed of, for example, a base fabric and a surface material. The base fabric is made of a fabric formed by knitting fibers.

[0029] The surface material is disposed on the surface side of the base fabric, that is, the side facing the occupant, and is formed of a waterproof material. Polyvinyl chloride (PVC) is used as the waterproof material. Polyvinyl chloride has high waterproofness, is inexpensive, and has excellent processability. By using polyvinyl chloride as the material of the surface material, it can be used as synthetic leather by performing surface processing while maintaining waterproofness. The surface material may be formed of polyethylene or polyurethane. The skin materials 12, 22, and 32 are fixed by fixing their ends to the bottom plate 10 or the headrest support member 30 with staples or the like.

[0030] <Ratchet mechanism 4> As shown in FIGS. 1 and 3, the vehicle seat S1 is provided with a ratchet mechanism 4 at the lower end of the headrest 3, in other words, at the connection portion 13 between the headrest 3 and the seat back 1. The headrest 3 is rotatably connected to the seat back 1 by the ratchet mechanism 4 about a rotation axis 42 in the front-rear direction. The ratchet mechanism 4 enables the rotated and tilted headrest 3 to be fixed at a predetermined angle. A plurality of predetermined angles are set and multi-stage fixing is possible. By moving the headrest 3 to a position suitable for the physique of the occupant by the ratchet mechanism 4 and fixing it so as to appropriately support the head of the occupant, the supportability and safety of the head during seating can be improved.

[0031] As shown in FIG. 3, the ratchet mechanism 4 includes a rotation shaft 42, a shaft support portion 33 that supports the rotation shaft 42, and a cam 41 provided on the rotation shaft 42. Teeth 44 are provided at the front end of the shaft support portion 33 and are provided to engage with the claw portion 43. A wall portion 45 extending forward is formed on the headrest support member 30. The wall portion 45 is arranged such that the tip of the arm portion extending from the cam 41 abuts against the contact points 45a and 45b of the wall portion 45 during rotation. The claw portion 43 restricts the rotation of the shaft support portion 33 having the teeth 44 in one direction, enabling the position of the headrest 3 to be fixed at a predetermined angle. Further, a cover 46 for hiding the ratchet mechanism 4 is provided below the claw portion 43.

[0032] <Headrest support member 30> As described above, a bottom plate 10, which is a back member, is provided on the back surface of the seat back 1. The bottom plate 10 is provided so as to cover the back surface of the headrest 3 as well. A headrest support member 30 for supporting the headrest pad 31 is provided on the headrest 3. As shown in FIG. 3, the headrest support member 30 is disposed in front of the bottom plate 10. As shown in FIG. 3, a gap C is formed between the bottom plate 10 and the headrest support member 30. By arranging the headrest support member 30 so that the gap C is formed, it is possible to suppress the generation of abnormal noise due to the contact between the bottom plate 10 and the headrest support member 30.

[0033] Further, since the headrest pad 31 is not directly supported by the bottom plate 10, providing the headrest support member 30 can suppress a decrease in the rigidity of the headrest 3. Since the headrest pad 31 and the headrest support member 30 can rotate integrally, the headrest 3 can be rotated while maintaining the rigidity of the headrest 3.

[0034] <Connecting member 14> As shown in FIG. 4, the bottom plate 10 is provided with a connecting member 14 extending forward at the connecting portion 13 between the seat back 1 and the headrest 3. The headrest support member 30 is connected to the bottom plate 10 by the connecting member 14. By connecting with the connecting member 14, the rigidity of the connecting portion 13 can be enhanced.

[0035] <Concave portion 15> The bottom plate 10 has a concave portion 15 that is recessed forward at the connecting portion 13 between the headrest 3 and the seat back 1. The connecting member 14 is attached so as to extend forward from the bottom of the concave portion 15. The formation of the concave portion 15 at the connecting portion 13 with the headrest 3 increases the rigidity of the bottom plate 10, and since the connecting member 14 extends forward from the bottom 15a of the concave portion 15, the headrest 3 can be supported more stably. Note that the concave portion 15 is formed as a groove extending in the seat width direction when viewed from the back.

[0036] <Position of the ratchet mechanism 4> The ratchet mechanism 4 (more specifically, the rotation shaft 42 of the ratchet mechanism 4) is provided at substantially the center of the lower surface 3a of the headrest 3 in the front-rear direction of the seat as shown in FIG. 3. By being provided at the center of the lower surface 3a of the headrest 3, the headrest 3 can be rotated in the front-rear direction in a well-balanced manner. Also, as shown in FIG. 2, the ratchet mechanism 4 is provided at the center of the lower surface 3a of the headrest 3 in the seat width direction. By providing the ratchet mechanism 4 at the center of the lower surface 3a of the headrest 3, the headrest 3 can be supported and rotated in a well-balanced manner.

[0037] <Shaft support portion 33> The headrest support member 30 has a shaft support portion 33 that protrudes forward at its lower end and supports the rotation shaft 42 of the ratchet mechanism 4. By having the shaft support portion 33 that protrudes forward, the attachment of the ratchet mechanism 4 becomes easy, and the assemblability of the headrest 3 is improved.

[0038] <Flexure portion> Also, on the headrest support member 30, in the vicinity of the base (rear end portion) of the shaft support portion 33, a flexure portion 34 is provided at a portion facing the concave portion 15 of the bottom plate 10 along the shape of the concave portion 15. As shown in FIG. 3, the flexure portion 34 extends upward from the rear end portion of the shaft support portion 33, and after exceeding the upper end of the concave portion 15, it bends backward. By providing the flexure portion 34 on the headrest support member 30, contact with the bottom plate 10 can be avoided and the generation of abnormal noises and the like can be suppressed.

[0039] <Inclined portion 19> On the upper surface of the seat back 1, as shown in FIG. 3, an inclined portion 19 that slopes downward is provided from the connection portion 13 with the headrest 3. By providing the inclined portion 19 on the upper surface of the seat back 1, when the headrest 3 rotates, interference between the headrest 3 and the seat back 1 can be avoided.

[0040] <<Second Embodiment>> The second embodiment of the present invention will be described with reference to FIGS. 5 and 6. The second embodiment relates to a vehicle seat, and particularly to a vehicle seat that is used outdoors and may be exposed to wind and rain.

[0041] FIG. 5 is an exploded perspective view showing the configuration of the seat back 201 of the vehicle seat S2 according to the second embodiment, and FIG. 6 is a cross-sectional view taken along line VI-VI of FIG. 5 showing the attachment method of the back member 220d.

[0042] Conventionally, in a vehicle seat, in order to perform color separation on the surface, the skin divided into a plurality of pieces was sewn together and assembled by covering a cushion sheet or the like. However, in a vehicle seat that may be exposed to wind and rain, there remained a possibility of water ingress from the sewn portion.

[0043] The seat back 201 of the vehicle seat S2 according to the present embodiment is composed of a bottom plate 210 serving as the base of the seat back 201 and a plurality of back members 220a to 220d (hereinafter sometimes collectively referred to as the back member 220) arranged on the bottom plate 210. The back members 220a to 220d are divided into parts for each color. By combining the colored back members 220a to 220d and attaching them to a predetermined position on the bottom plate 210, the color - separated seat back 201 can be assembled.

[0044] Each of the back members 220a to 220d is composed of a cushion 221, a cushion support member 223 that supports the cushion 221, and a skin material 222 that covers the cushion 221, as shown in FIG. 6. The end of the skin material 222 is fixed to the cushion support member 223 by staples 224.

[0045] As shown in FIG. 6, the fixing of the back member 220 to the bottom plate 210 is performed by engaging a claw portion 225 formed at the bottom of the cushion support member 223 of the back member 220 with an engagement hole 211 formed in the bottom plate 210. Since each of the back members 220 is covered by a single skin material 222, water immersion is suppressed, improving waterproof performance. Also, since the back members 220 are color - separated, a vehicle seat S2 having a plurality of colors can be provided. Further, by forming each back member 220 as a blow - molded product, the assemblability is improved and the waterproof performance is also enhanced, thus reducing the manufacturing cost.

[0046] <<Third Embodiment>> The third embodiment of the present invention will be described with reference to FIGS. 7 to 8C. The third embodiment relates to a vehicle seat, and particularly to a vehicle seat that may be exposed to wind and rain.

[0047] FIG. 7 is a view showing a vehicle seat S3 in which a drain hole 314 is formed in the seat back 301. FIG. 8A is a perspective view of the vehicle seat S3A seen from obliquely forward, and FIG. 8B is a cross-sectional view taken along line B-B of FIG. 8A. FIG. 8C is a perspective view showing the back surface of the skin material 312A provided with a cylindrical member provided around the through hole.

[0048] Conventionally, in a vehicle seat that may be exposed to wind and rain, there has been a problem that water is not properly drained from the seat surface portion and water accumulates on the seat surface portion. In addition, when sitting on a vehicle seat, the lower end of the seat back rarely contacts the waist (vertebra) of the seated person, and even if a padding material or the like is arranged at the lower end of the seat back, its function may not be exerted.

[0049] In addition, for heat (stuffiness) countermeasures, a detachable seat cover made of a mesh material may be further attached by the user's hand. Although putting on the seat cover can suppress stuffiness, foreign substances such as dust may be mixed into the mesh of the seat cover, or dirt may enter the fibers, so the appearance of the seat may deteriorate.

[0050] Therefore, in the vehicle seat S3 shown in FIG. 7, a cavity 314 is formed at the lower end of the seat back 301 so that the water accumulated in the seat cushion 302 is discharged. By forming the cavity 314, the accumulation of water in the seat cushion 302 is suppressed. In addition, as shown in FIG. 7, the seat back 301 is composed of a padding material 311 made of a urethane material and a skin material 312 covering the padding material 311. By forming the cavity 314 in the seat back 301, the amount of urethane material constituting the padding material 311 can be reduced.

[0051] In the vehicle seat S3A shown in FIG. 8A, a plurality of through holes 315 penetrating the seat cushion 302A in the vertical direction are formed, and water accumulated on the surface is configured to be drained from the through holes 315 under the seat cushion 302A. Since the water accumulated on the seating surface can be discharged and air can also circulate, the stuffiness of the seat cushion 302A can be suppressed. Therefore, it is not necessary to separately provide a seat cover for preventing stuffiness, and foreign matter intrusion and dirt can be prevented.

[0052] Note that the surface of the seat cushion 302A of the seat cushion 302A is inclined so that water flows into the through holes 315. Also, in order to maintain waterproofness, a skin material 312A is provided on the wall surface of the through holes 315. The skin material 312A inside the through holes 315 is produced, for example, as shown in FIG. 8C, by providing a cylindrical member 313 formed of the skin material on the back surface of the skin material and passing the cylindrical member 313 through the through holes 315 formed in the seat back 301A.

[0053] <<Fourth Embodiment>> The fourth embodiment of the present invention will be described with reference to FIG. 9. The fourth embodiment relates to a vehicle seat, and particularly to a vehicle seat that may be exposed to wind and rain.

[0054] FIG. 9 is a schematic cross-sectional view showing the configuration of a seat cushion 402 including cushion materials having different hardnesses. Conventionally, when molding the cushion pad of a seat cushion, since it is difficult to foam with different hardnesses, foaming has been prioritized with respect to the hardness of the seating surface on which the seated person directly sits. Therefore, there has been a problem that an appropriate hardness cannot be given to the gusset part of the seat cushion.

[0055] In the vehicle seat S4 of this embodiment, as shown in FIG. 9, a first pad 421 is formed using a normal urethane member for the portion that becomes the seat surface, and a second pad 422 made of rigid urethane having a higher hardness than the normal urethane member is inserted inside the portion corresponding to the edge part of the seat cushion 402. That is, the vehicle seat S4 is composed of a first pad 421 and a second pad 422 that is harder than the first pad 421. The second pad 422 may be provided in the first pad 421 by insert molding. The first pad 421 is covered with a skin material 423, and the skin material 423 is fixed to the bottom plate 420 by staples 424.

[0056] As shown in FIG. 9, the second pad 422 provided at the edge part may be directly fixed to the bottom plate 420 by staples 424. Also, at the end of the bottom plate 420, as shown in FIG. 9, there is a portion where the thickness of the second pad 422 becomes thinner (fixed corner part 420a). In such a place, the staples 424 can be driven through the second pad 422 and reach the first pad 421, and both the first pad 421 and the second pad 422 can be fixed to the bottom plate 420. Since both pads (the first pad 421 and the second pad 422) are fixed at the fixed corner part 420a, the fixing property of the entire urethane can be improved. Also, by providing the second pad 422 made of rigid urethane at the edge part, the hardness of the edge part can be increased and the support property can be improved.

[0057] <<Fifth Embodiment>> Next, the fifth embodiment of the present invention will be described with reference to FIGS. 10 to 13B. The fifth embodiment relates to a vehicle seat, and particularly to a vehicle seat whose shape can be adjusted according to the difference in the physique of the occupant.

[0058] FIG. 10 is a front view showing a seat back 501 of a vehicle seat S5 having a rotatable seat back member 504, and FIG. 11 is a view of a base member 513 that supports the rotatable seat back member 504 as seen from the front, and is an explanatory view showing the operation of the support member 515. It is a view seen from the front. FIG. 12 is a view showing the rotatable seat back member 504 along the line XII-XII of FIG. 10, and is an explanatory view showing the operations of the seat back member 504 and the support member 515. FIG. 13A is a cross-sectional view showing a stopper 516 that stops the tip of the support member 515, and FIG. 13B is a view showing another example of the stopper 516.

[0059] Conventionally, for vehicle seats used outdoors, a flat-shaped or seat back with no change in shape has been adopted. Since vehicle seats used outdoors may be exposed to wind and rain, it has been difficult to provide a mechanism for changing the shape. Therefore, an object of the present embodiment is to provide a vehicle seat having a physique adjustment mechanism that can be easily manually adjusted to fit the physique of the occupant.

[0060] The vehicle seat S5 of the present embodiment includes a seat back 501 that supports the back of the occupant, and the seat back 501 is provided with a seat back member 504 that can rotate according to the back of the occupant. The seat back 501 is composed of a bottom plate 510, a padding material 511 disposed on the bottom plate 510, and a skin material 512 that covers the padding material 511. At positions corresponding to the back of the seated occupant, seat back members 504 that are movable independently of the seat back 501 are provided on both sides. The seat back member 504 can rotate in the front-rear direction with a hinge 517 extending in the vertical direction as a rotation axis.

[0061] As shown in FIG. 12, the seat back member 504 is composed of a base member 513 that is rotatably connected to the bottom plate 510 of the seat back 501 by a hinge 517, a padding material 511 disposed on the base member 513, and a skin material 512 that covers the padding material 511. In addition, the base member 513 is provided with a support member 515 that fixes the position of the base member 513 at a predetermined angle when the seat back member 504 is rotated.

[0062] The support member 515 is rotatably attached to the base member 513 by a hinge 518. The support member 515 can be supported by deploying the support member 515 toward the bottom plate side (in the direction of arrow B in FIG. 12) after the seat back member 504 has rotated. As shown in FIG. 12, the bottom plate 510 is provided with a plurality of stoppers 516 for stopping the tip of the support member 515 at equal intervals. By bringing the tip of the support member 515 into contact with any one of the stoppers 516, the occupant can fix the position of the seat back member 504 at a desired angle.

[0063] The stopper 516 shown in FIG. 13A is formed with a semicircular cross section, but the shape of the stopper 516 is not limited to this. For example, as shown in FIG. 13B, a plurality of stoppers 516A having a C-shaped cross section may be arranged on the bottom plate 510 at equal intervals. When the tip of the support member 515 bulges roundly, the tip of the support member 515 can be held by the stopper 516A, thereby suppressing, for example, the forward movement of the seat back member 504.

[0064] According to the vehicle seat S5 of the present embodiment, the shape of the seat can be manually deformed by the seat back member 504 rotatably provided on the seat back 501, and it is possible to adjust according to the physique of the occupant. In the present embodiment, the seat back 501 is provided with a rotatable seat back member 504. However, a rotatable seat cushion member having a similar structure may be provided on the side portion of the seat cushion to change the shape according to the occupant's buttocks or the like.

[0065] <<Sixth Embodiment>> The sixth embodiment of the present invention will be described with reference to FIG. 14. The sixth embodiment relates to a vehicle seat, and particularly to a vehicle seat that may be exposed to wind and rain. FIG. 14 is an explanatory diagram for explaining a method of manufacturing an epidermal surface having irregularities according to the sixth embodiment.

[0066] In a conventional vehicle seat, in order to provide irregularities on its appearance, three parts (epidermal surface, cushion, and cover) are used, resulting in problems such as high material costs, many assembly processes, and high manufacturing costs. In the vehicle seat of this embodiment, in order to provide an uneven feeling on the seat surface, as shown in FIG. 14, the cushion 613 (also called a slab) and the epidermal material 612 are used to express irregularities.

[0067] Specifically, as shown in the upper part of FIG. 14, the epidermal material 612 is laminated (laminated) on the cushion 613, and the processed cushion 613 and epidermal material 612 are pressed against a welder 630 having irregularities, so that as shown in the lower part of FIG. 14, recesses 614 are formed on the surface of the epidermal material 612 to create an uneven feeling. Since the welder 630 creates an uneven feeling on the surface of the epidermal material 612, there is no need to process the cover provided under the cushion as in the conventional case. Material costs and assembly processes can be reduced, and an increase in processing costs can be suppressed.

[0068] <<Seventh Embodiment>> The seventh embodiment of the present invention will be described with reference to FIGS. 15A to 16. The seventh embodiment relates to a vehicle seat, and particularly to a vehicle seat that is used outdoors and may be exposed to wind and rain.

[0069] FIG. 15A is a perspective view showing a vehicle seat S7 according to the seventh embodiment, and is a view of the vehicle seat S7 provided with a decorative line by a seat belt 704. FIG. 15B is a perspective view of the vehicle seat S7 with the seat belt removed. FIG. 16 is a cross-sectional view taken along line XVI-XVI of FIG. 15A.

[0070] In conventional outdoor vehicles, safety is highly regarded due to the intense driving style, and a thicker and wider seat belt than the ordinary seat belt for four-wheel vehicles is used. Therefore, the presence of the seat belt is significant and has contributed to a decline in design.

[0071] The vehicle seat S7 of this embodiment includes a seat back 701 that supports the back of the occupant, a seat cushion 702 that supports the buttocks, and a headrest 703 that is provided above the seat back 701 and supports the head of the occupant. A back pad 711 and a skin material 712 that covers the back pad 711 are provided on the seat back 701, the seat cushion 702, and the headrest 703. Also, as shown in FIG. 15A, a seat belt 704 for fixing the seated occupant is provided. As shown in FIG. 15B, a decorative accent line 705 is applied to the seat back 701. The seat belt 704 is also provided with a decorative accent line similar to the decorative accent line 705 provided on the seat back 701, improving the design of the vehicle seat S7.

[0072] Also, as shown in FIGS. 15B and 16, a recess 701a for storing the seat belt 704 is formed in the seat back 701. When the occupant is not seated, by storing the seat belt 704 in the recess 701a, the appearance of the vehicle seat S7 approaches flatness. Thereby, the presence of the seat belt 704 is reduced, and the discomfort caused by the seat belt 704 when the occupant is seated can also be reduced.

[0073] <<Eighth Embodiment>> The eighth embodiment of the present invention will be described with reference to FIGS. 17 to 20. The eighth embodiment relates to a method for confirming the accuracy of silk printing, and particularly relates to a method for confirming the accuracy when performing silk printing using two or more colors of ink. FIG. 17 is a view showing a skin material 812 on which a logo is printed in two colors by silk printing, and FIG. 18 is a perspective view showing a printing apparatus 810 for silk printing. FIG. 19 is a view showing a first-color silk plate 821 and a second-color silk plate 822. FIG. 20 is an enlarged view of a part of FIG. 17 and is an explanatory view for explaining a quality control method.

[0074] Conventionally, silk printing has sometimes been used for printing characters, logo marks, etc. on vehicle seats used in outdoor vehicles. Silk printing is a method of pressing ink from above a plate (second-color silk plate 822 in FIG. 18) called a screen and printing characters, logo marks, etc. on a skin material 812 or the like disposed below. A cloth woven with chemical fiber yarns is used for the screen, and it is designed so that the ink passes only through the portion of the design to be printed. Therefore, it is usually performed in a single color in one printing. When printing in two or more colors, silk plates are prepared for each color and printing is performed using separate jigs. Therefore, misregistration may occur, but it has been difficult to judge how much misregistration has occurred just by looking at the printed matter. Therefore, in the case of printing in two or more colors, a method for confirming accuracy for appropriately judging printing accuracy has been demanded.

[0075] FIG. 17 shows an example in which a logo mark is printed in two colors on the skin material 812. The skin material 812 has a portion (waste portion 818) that is not visually recognized when attached to the seat. The waste portion 818 is a portion located outside the seam allowance 815. In the accuracy confirmation method of the present embodiment, by printing a confirmation mark simultaneously with the logo mark on the portion (waste portion 818) outside the seam allowance 815, misregistration can be visually detected.

[0076] Specifically, as in the first-color silk plate 821 shown in the upper part of FIG. 20, separately from the first-color logo mark 813, it is set to print a first mark 816 at a position that will become the waste portion 818 of the skin material 812. The first marks 816 are printed one on each side of the logo mark 813. In the present embodiment, for example, a circle with a diameter of 5 mm is printed as the first mark 816. Also, like the silk plate 822 for the second color shown in the lower part of FIG. 20, separate from the logo mark 814 of the second color, at the position that becomes the discard part 818 of the skin material 812 and overlapping the center of the first mark 816, it is set to print the second mark 817. In the silk plate 822 for the second color, circles with a diameter of 2 mm are printed as the second marks 817, one on each side of the logo mark 814 of the second color.

[0077] After printing using the silk plate 821 for the first color shown in the upper part of FIG. 20 and then printing using the silk plate 822 for the second color, when printed without misalignment, as shown by the solid line in FIG. 20, a circle slightly smaller (the second mark 817) is printed at the center of the circle with a diameter of 5 mm (the first mark 816). Since the second mark is printed inside the first mark 816, it can be visually determined that there is no misalignment.

[0078] Since printing is done using different silk plates, there is a possibility that the position of the second color may shift. If it shifts, it is printed off-center like the second mark 817a shown by the dotted line in FIG. 20. Even if it shifts, as long as it is inside the first mark 816 (the shift width L1 is 1.5 mm or less), since the misalignment is not large, the printing result can be regarded as acceptable and it can be determined that it was performed normally. On the other hand, when it protrudes from the first mark 816 like the second mark 817b (the shift width L2 is 2.0 mm or more), the printing is not performed normally and it can be determined that the logo mark is misaligned. In this way, it becomes possible to detect the misalignment of the second color even visually. In this embodiment, since the misalignment is managed within the range of ±1.5 mm, the printing accuracy can be confirmed and the quality can be improved.

[0079] <<Ninth Embodiment>> The ninth embodiment of the present invention will be described with reference to FIG. 21. The ninth embodiment relates to a vehicle seat, and particularly to a vehicle seat that is used outdoors and may be exposed to wind and rain.

[0080] FIG. 21 is a perspective view showing the vehicle seat S9 of the ninth embodiment. Conventionally, vehicles used outdoors are assumed to travel on rough terrain and the like, and a three-point seat belt is used to fix the occupants. In the conventional three-point seat belt, since it is worn diagonally, a four-point seat belt is used to hold the occupants more firmly. However, the four-point seat belt has many fastening points and has problems in terms of usability. In addition, there is a problem that it is costly to change from a three-point belt to a four-point belt.

[0081] The vehicle seat S9 of this embodiment includes a seat back 901 that supports the back of the occupant, a seat cushion 902 that supports the buttocks, and a headrest 903 that supports the head of the occupant above the seat back 901. The seat back 901 and the seat cushion 902 are composed of a bottom plate, a pad disposed on the bottom plate, and a skin material that covers the pad. Although not shown, the vehicle is provided with a three-point seat belt, which can hold the seated occupants.

[0082] In the vehicle seat S9 of this embodiment, as shown in FIG. 21, a hook-and-loop fastener 910 is attached to the seating surface of the seat back 901, more specifically, to the shoulders. A hook-and-loop fastener 930 is also attached to the headrest 903 at a position where it contacts the occupant's head. Since it is used outdoors, if the hook-and-loop fasteners 910 and 930 are attached by sewing, there is a possibility of water immersion. Therefore, it is desirable to attach the hook-and-loop fasteners 910 and 930 by welding.

[0083] A hook-and-loop fastener is sewn onto the occupant's clothing at a position (for example, the shoulder) corresponding to the hook-and-loop fastener 910 of the seat back 901. Also, a hook-and-loop fastener is attached to the occupant's helmet at a position (the rear part of the helmet) corresponding to the hook-and-loop fastener 930 of the headrest 903. When the occupant sits on the vehicle seat S9, the back of the occupant is fixed by the hook-and-loop fastener 910 on the seat back 901, and the displacement of the body can be suppressed. Further, the head of the occupant is fixed by the hook-and-loop fastener 930 of the headrest 903, and the neck of the occupant can be protected. Further, since the shaking of the body is also absorbed, it is difficult to cause whiplash.

[0084] When the three-point seat belt is already installed, by using the hook-and-loop fastener, it can be fixed more firmly, and the three-point seat belt can be continuously used. Further, since it is fixed by the hook-and-loop fastener, it can be easily removed, and it does not become as inconvenient as the four-point seat belt fixed by a plurality of buckles.

[0085] <<Tenth Embodiment>> The tenth embodiment of the present invention will be described with reference to FIGS. 22 and 23. The tenth embodiment relates to a vehicle seat, and particularly to a vehicle seat that is used outdoors and may be exposed to wind and rain. FIG. 22 is a schematic cross-sectional view showing the configuration of a vehicle seat S10 in which a cushion pad 1021 is fixed to a bottom plate 1020 by a hook-and-loop fastener 1024, and FIG. 23 is a schematic cross-sectional view showing the state before the cushion pad 1021 is attached.

[0086] Conventionally, for vehicle seats such as golf carts used outdoors, a pad material was arranged on the bottom plate, the pad was covered with a skin material, and the skin material was fixed with staples or adhesives. Further, a frame member was inserted into the pad, and the bottom plate and the frame member were assembled by fastening them with bolts. However, vehicles such as golf carts usually travel at a low speed, and a violent riding style is not performed. Therefore, the load on the seat is less than that of a normal vehicle. Therefore, it has been required to reduce the manufacturing cost by assembling in a relatively simple method.

[0087] The vehicle seat S10 of this embodiment is a seat for a vehicle used outdoors such as a golf cart. The seat cushion 1002 that supports the occupant's buttocks is composed of a bottom plate 1020, a cushion pad 1021, and a skin material 1022 that covers the cushion pad 1021. The skin material 1022 and the cushion pad 1021 are formed by integral foaming. A hook-and-loop fastener 1024 is attached to the bottom surface of the cushion pad 1021. On the upper surface of the bottom plate 1020, a hook-and-loop fastener 1024 is also provided at a position corresponding to the hook-and-loop fastener 1024 of the cushion pad 1021. By placing the cushion pad 1021 integrated with the skin material 1022 on the bottom plate 1020, the vehicle seat S10 can be assembled.

[0088] Conventionally, as the steps for assembling a vehicle seat, (1) the step of taking out the bottom plate, skin material, and cushion, (2) the step of applying an adhesive to the bottom plate, (3) the step of setting the skin material and the cushion pad, (4) the step of bonding, and (5) the step of pressure bonding were performed to assemble the seat cushion.

[0089] In the vehicle seat S10 of this embodiment, since it is fixed using a hook-and-loop fastener integrally formed with the cushion pad 1021, the conventionally performed steps of (2) applying an adhesive, (3) setting the skin material and the cushion pad, and (5) pressure bonding can be reduced. Therefore, it is possible to significantly reduce the man-hours compared to the conventional construction method.

[0090] When inserting the hook-and-loop fastener 1024 into the cushion pad 1021, the hook-and-loop fastener 1024 with a magnet attached or adhered may be attached to the mold using magnetic force, and in this state, the cushion pad 1021 may be foamed in the mold. The hook-and-loop fastener 1024 and the cushion pad 1021 can be integrally formed with the hook-and-loop fastener 1024 exposed on the surface of the cushion pad 1021.

[0091] The attachment of the hook-and-loop fastener 1024 to the cushion pad 1021 may be achieved by integrally foaming the skin material 1022 and the cushion pad 1021 and then attaching them to the back surface of the cushion pad 1021 with an adhesive. As shown in FIG. 23, by placing the cushion pad 1021, which is integrated with the skin material 1022 and has the hook-and-loop fastener 1024 attached to its back surface, on the bottom plate 1020 to which the hook-and-loop fastener 1024 has been attached in advance, the seat cushion 1102 of the vehicle seat S10 can be completed. As described above, since work processes such as the coating process and the crimping process of applying the adhesive can be reduced, man-hour reduction can be achieved compared to the conventional method.

[0092] <<Eleventh Embodiment>> The eleventh embodiment of the present invention will be described with reference to FIGS. 24 to 26B. The eleventh embodiment relates to a vehicle seat, and particularly to a vehicle seat that is used outdoors and may be exposed to wind and rain. FIG. 24 is a bottom view of the cushion pad 1121 used for the seat cushion of the vehicle seat S11 as viewed from below, and FIG. 25 is a partially enlarged view showing an enlargement of part A in FIG. 24. FIG. 26A is a cross-sectional view taken along line A-A in FIG. 25, and schematically shows the upper die 1131 and the lower die 1132 for forming the cushion pad 1121. FIG. 26B is a cross-sectional view taken along line B-B in FIG. 25, and schematically shows the die for forming the cushion pad 1121 at the portion where the joint 1124 is located.

[0093] In the seat cushion of the vehicle seat, a plurality of through-holes 1122 for suspension are formed as shown in FIG. 24 in order to suspend the skin material. However, when the through-holes 1122 are formed, there is a problem that at the portion that becomes an opening (the portion indicated by the circled B in FIG. 26A) during molding, a standing wall is formed and air is likely to accumulate.

[0094] Therefore, in the cushion pad 1121 used in this embodiment, as shown in FIGS. 24 and 25, by providing a connection 1124 at the central portion of the through hole 1122 used for suspension, the air permeability is improved, and the accumulation of air around the opening of the through hole 1122 is suppressed. That is, by creating the connection 1124 even partially, since the wall of the mold for molding also becomes partially absent, the air permeability improves, and the accumulation of air is suppressed. By improving the air permeability, the lack of material around the through hole 1124 for suspending the cushion pad 1121 is less likely to occur, and the moldability of the cushion pad 1121 is improved.

[0095] Note that a recess 1123 for fixing the suspension plate is formed around the through hole 1122. Further, the connection 1124 provided in the through hole 1122 is penetrated by passing the suspension plate during suspension, so it does not remain.

[0096] <<Twelfth Embodiment>> The twelfth embodiment of the present invention will be described with reference to FIGS. 27 to 28. The twelfth embodiment relates to a vehicle seat, and particularly to a vehicle seat that may be exposed to wind and rain. FIG. 27 is a schematic cross-sectional view showing the configuration of a seat back in a conventional vehicle seat, and FIG. 28 is a schematic cross-sectional view showing the configuration of the seat back 1201 of the vehicle seat S12 of this embodiment.

[0097] In a conventional vehicle seat, as shown in FIG. 27, the end of the skin material 11212 fastened to the bottom plate 11210 is close to the vehicle frame 11220, and there is a problem that the skin material 11212 is sandwiched between the bottom plate 11210 and the vehicle frame 11220, resulting in skin breakage.

[0098] As shown in Fig. 28, the vehicle seat S12 of the present embodiment includes a bottom plate 1210, a back pad 1211 disposed on the bottom plate 1210, and a skin material 1212 covering the back pad 1211. The skin material 1212 is fixed to the bottom plate 1210 by staples 1213. On the bottom plate 1210, ribs 1214 extending rearward are formed at positions close to the vehicle frame 1220. The skin material 1212 is fastened to the bottom plate 1210 at a position outside the ribs 1214. Since the ribs 1214 are provided between the end of the skin material 1212 and the vehicle frame 1220, the frame 1220 and the skin material 1212 do not come into direct contact, suppressing the occurrence of skin breakage.

[0099] <<13th Embodiment>> The 13th embodiment of the present invention will be described with reference to Figs. 29 and 30. The 13th embodiment relates to a vehicle seat, and particularly to a vehicle seat that may be exposed to wind and rain. Fig. 29 is a schematic cross-sectional view showing the configuration of a seat back in a conventional vehicle seat, and Fig. 30 is a schematic cross-sectional view showing the configuration of the seat back 1301 of the vehicle seat S13 of the present embodiment.

[0100] In a conventional vehicle seat, when the seat back 11301 is viewed from the rear, as shown in Fig. 29, the staples 11313 for fastening the skin 11311 to the bottom plate 11310 are visible, resulting in a problem of deterioration of the appearance design (look) of the vehicle seat. To improve the look, it is possible to further add a cover to hide the staples 11313, but there is a concern that the manufacturing cost will increase due to an increase in members and assembly processes.

[0101] As shown in Fig. 30, the vehicle seat S13 of the present embodiment includes a bottom plate 1310, a back pad 1311 disposed on the bottom plate 1310, and a skin material 1312 covering the back pad 1311. The bottom plate 1310 is formed with ribs 1314 extending rearward from the position where the end of the conventional skin was fastened by staples. The skin material 1312 is extended so as to be disposed from the end of the bottom plate 1310 to the tip of the rib 1314, and the end of the skin material 1312 is bent forward. The end of the skin material 1312 is fastened by staples 1313 at the side of the rib 1314.

[0102] Even when the vehicle seat S13 is viewed from the rear, since the direction in which the staple 1313 fastens the skin material 1312 is rotated 90 degrees from the conventional one, the staple 1313 is suppressed from being directly visible, and the appearance of the back surface of the seat back 1301 can be improved. Also, by adding the rib 1314 to the bottom plate 1310, the bottom plate 1310 can be reinforced.

[0103] <<The Fourteenth Embodiment>> Next, the fourteenth embodiment of the present invention will be described with reference to FIGS. 31 to 34. The fourteenth embodiment relates to a vehicle seat, and particularly to a vehicle seat that may be exposed to wind and rain outdoors.

[0104] Conventionally, a vehicle seat has been composed of a bottom plate, a pad material disposed on the bottom plate, and a skin covering the pad material. And, in order to fasten the skin, hooks provided around the bottom surface of the bottom plate have been used. The skin wraps around the end of the pad material placed on the bottom plate and is hooked on the hooks. Usually, these hooks are formed symmetrically about an axis orthogonal to the hooking direction. However, the conventional hooks do not consider the directionality of hooking the skin, and a hook shape that is easier to hook the skin has been demanded. For example, after hooking a hole in the skin, it is hooked by pushing it in. However, when the hooks are formed symmetrically, there is not enough space to push in the skin, making it difficult to push in and there may be a case where the skin does not fully hook (a half-hooked state).

[0105] Hereinafter, a motorcycle seat will be cited as an example of a vehicle seat, and its configuration example will be described. However, the present invention is not limited to a motorcycle seat, and may be a four-wheel or three-wheel vehicle seat mounted on a ground vehicle having wheels such as an automobile or a railway, or a seat mounted on an aircraft or a ship that moves other than on the ground.

[0106] FIG. 31 is a perspective view showing the bottom surface of the motorcycle seat S14 of the present embodiment, and FIG. 32 is a partially enlarged perspective view showing a partial enlargement of part A in FIG. 31. Further, FIG. 33 is a side view showing the configuration of the hook 1420, and FIG. 34 is an explanatory view for explaining the procedure of hanging the skin material 1412 on the hook 1420.

[0107] The motorcycle seat S14 is a seat used for, for example, a motorcycle. The motorcycle seat S14 is composed of a bottom plate 1410, a cushion pad 1411 as a cushioning material placed on the bottom plate 1410, and a skin material 1412 covering the cushion pad 1411 (see FIG. 34).

[0108] The bottom plate 1410 is a member that serves as the base of the motorcycle seat S14. As shown in FIG. 31, a plurality of hooks 1420 for hanging the skin are provided around the bottom surface. The cushion pad 1411 is, for example, a urethane pad formed by foam molding using a urethane foaming agent.

[0109] The skin material 1412 is a member that covers the bottom plate 1410 with the cushion pad 1411 placed thereon, and is fixed by being hung on a plurality of hooks 1420 provided around the bottom surface of the bottom plate 1410. The skin material 1412 is composed of a base fabric and a surface material disposed on its surface. The base fabric is made of, for example, a fabric formed by knitting fibers. The surface material is formed from a waterproof material. In this embodiment, polyvinyl chloride (PVC) is used as the waterproof material. By using polyvinyl chloride as the material of the surface material, it can be used as synthetic leather by performing surface treatment while maintaining waterproofness. The material of the surface material may be polyethylene or polyurethane.

[0110] Hereinafter, the side where the operator hangs the skin material 1412 on the hook 1420 will be referred to as the back side, and the opposite side will be referred to as the front side. As shown in FIG. 31, a plurality of hooks 1420 for hanging the skin material 1412 are provided on the bottom surface of the bottom plate 1410. The hook 1420 of this embodiment is composed of a column portion 1421 standing upright from the bottom surface and a hook head portion 1422 provided at the top thereof. And the shape of the hook head portion 1422 is formed such that the height H1 on the back side and the height H2 on the front side are different, as shown in FIG. 33. More specifically, the height H1 from the surface of the bottom plate 1410 to the lower surface of the hook head portion 1422 located on the back side is formed to be lower than the height H2 to the lower surface of the hook head portion 1422 located on the front side.

[0111] Also, the length L1 to the tip of the hook head portion 1422 located on the back side and the length L2 to the tip of the hook head portion 1422 located on the front side are different, and the length L1 on the back side is configured to be shorter than the length L2 on the front side.

[0112] If the height H1 on the back side and the height H2 on the front side are the same height, the hook angle becomes gentle, so when pushing in the skin material, the skin material may stop halfway and be half-hooked. By making the height H2 on the front side higher than the height H1 on the back side, as shown in FIG. 34, it is possible to secure a pushing-in space for pushing in the skin material 1412. Further, by making the height H2 on the front side higher, the angle of the hook 1420 becomes steep, making it difficult for the skin material 1412 to stop and easy to slide down.

[0113] When hanging the skin material 1412, after hanging the back side of the hook hole, strongly pull in the direction of arrow A in FIG. 34. When the front side of the hook hole exceeds the front side of the hook head, strongly pull (push) in the direction of arrow B in FIG. 34 to hang the skin material 1412. Since it becomes easier to hang the hook hole on the hook, it is possible to suppress a half-hung state where the skin material 1412 does not fully hang. Note that the structure of the hook 1420 in the present embodiment for hanging the skin material 1412 is not limited to the application only to the seat for a two-wheeled vehicle, and can also be applied to the seat for a four-wheeled vehicle.

[0114] As described above, the first to fourteenth embodiments of the present invention have been described with reference to the drawings. As an example of the present invention, a vehicle seat directly exposed to wind and rain used in a four-wheel buggy has been given, and its configuration example has been described. However, the present invention may also be applied to a vehicle seat that is not directly exposed to wind and rain.
