Description

[Technical field]

[0001] The present invention relates to a straddle-type seat, and more particularly to a straddle-type seat equipped with a backrest. [Background technology]

[0002] In some motorcycle seats, a front seat for the rider is provided behind a rear seat for other riders, and a backrest for the rider to lean against is provided on the step located at the boundary between the two seats. For such motorcycle seats, a technique is known for adjusting the backrest in the fore-aft direction to change the rider's seating position.

[0003] Patent document 1 describes that by pulling a strap attached to one end of the locking plate as an operating member in the lateral unlocking direction, the fitting hole in the locking plate disengages from the fitting slit in the pipe frame, making it possible to adjust the backrest in the fore-and-aft direction. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] International Publication No. 2016 / 021414 Summary of the Invention [Problem to be solved by the invention]

[0005] In the technology described in Patent Document 1, a strap is attached to the lock plate, resulting in a large number of parts.

[0006] The present invention has been made in consideration of the above problems, and has an object to provide a straddle-type seat that has a movable backrest while reducing the number of parts. [Means for solving the problem]

[0007] The above-mentioned problem is solved by the vehicle seat of the present invention, which is a straddle-type seat having a backrest movable relative to a seat body, the backrest having an adjustment member extending in a moving direction of the backrest, the seat body having a bottom plate through which the adjustment member is inserted, a locking member that prevents the backrest from moving by contacting the adjustment member, and a cover member that covers the locking member, the cover member completely covering the adjustment member. The locking member has an operating portion that is operated when the backrest is moved, the operating portion protruding outward from the cover member, the cover member having a recessed portion recessed upward, the operating portion being disposed in the recessed portion and protruding outward from an opening formed in the cover member, the locking member having a bent portion bent from the operating portion, the bent portion being disposed so as to fill a gap between the operating portion and the opening in a bottom view of the straddle-type seat. This is solved by:

[0008] In the straddle-type seat of the present invention configured as described above, grease is applied to the surface of the adjustment member to enable the adjustment member to slide smoothly, but by completely covering the adjustment member with the cover member, it is possible to prevent the grease from dripping downward and adhering to the vehicle body, etc. Furthermore, in the above configuration, it is possible to prevent foreign matter from entering by filling the gap between the locking member and the cover member around the opening.

[0009] In the above-mentioned straddle-type seat, an extension portion is formed on the cover member, extending in the movement direction of the adjustment member, and the extension portion may overlap with the adjustment member in the vertical direction of the straddle-type seat. With the above configuration, it is possible to properly cover the adjustment member, and therefore it is possible to prevent the grease from dripping downward and adhering to the vehicle body, etc.

[0011] In the above-mentioned straddle-type seat, in a locked state in which movement of the backrest is prevented, the length of the portion where the folding portion and the cover member overlap in the vertical direction of the straddle-type seat is preferably longer than the maximum movement amount of the locking member. With the above-described configuration, it is possible to prevent foreign matter from entering even in a state in which the locking member is slid to release the lock.

[0012] In the above-mentioned straddle-type seat, the operating portion has a bottom portion extending in the width direction of the straddle-type seat and a connecting portion connecting the bottom portion and the folding portion, and the folding portion may be shorter than the connecting portion. With the above configuration, the operation unit can be made compact.

[0013] In the above-mentioned straddle-type seat, the operating portion may preferably have a side wall bent from the bottom portion at a position opposite the connecting portion in the width direction of the straddle-type seat. In the above configuration, when operating the operating portion, it is possible to pinch and grasp the connecting portion and the side wall with fingers, improving operability.

[0014] In the above-mentioned straddle-type seat, a through hole through which the adjustment member is inserted is formed in the bottom plate, and a protective member is provided in front of the through hole, and the protective member has a protective portion through which the adjustment member is inserted, and the protective portion is preferably formed to be longer on the upper side than on the lower side. The above configuration prevents water from entering through the gap and wetting the adjustment member when the backrest is moved, and by lengthening the upper side of the protective part, water is prevented from entering the mating part between the adjustment member and the locking member even when the adjustment member is moved to the frontmost part.

[0015] In the above-mentioned straddle-type seat, it is preferable that the protective portion has a ring-shaped rib portion protruding inward, the rib portion abutting against the outer surface of the adjustment member. With the above configuration, it is possible to properly seal the gap between the inner surface of the protective portion and the outer surface of the pipe frame, thereby preventing water from entering the inside of the sheet body.

[0016] The above-mentioned problem is solved by the vehicle seat of the present invention, which is a straddle-type seat having a backrest movable relative to a seat body, the backrest having an adjustment member extending in a moving direction of the backrest, the seat body having a bottom plate through which the adjustment member is inserted, a locking member that prevents the backrest from moving by contacting the adjustment member, and a cover member that covers the locking member, the cover member completely covering the adjustment member, The locking member has an operating portion that is operated when the backrest is moved, and a plurality of the adjustment members are provided, the operating portion being a plurality of bolts provided to engage with the plurality of the adjustment members, and a reinforcing portion is provided between the plurality of bolts. This is solved by: In the straddle-type seat of the present invention configured as described above, grease is applied to the surface of the adjustment member to enable the adjustment member to slide smoothly, but by completely covering the adjustment member with the cover member, it is possible to prevent the grease from dripping downward and adhering to the vehicle body, etc. In addition, in the above configuration,If the operating part is a bolt, then as many bolts are required as there are adjustment parts, and there will be multiple bolt receiving holes in the cover member, making it possible to reinforce weak parts between the bolt receiving holes and increase strength. Effect of the Invention

[0017] According to the straddle-type seat of the present invention, the locking member is covered with a cover member to improve the appearance, while the locking member is directly moved by an operating unit provided in the center of the width of the straddle-type seat, making it possible to reduce the number of parts. Furthermore, according to the straddle-type seat of the present invention, it is possible to arrange the operating unit in a compact manner. Furthermore, with the straddle-type seat of the present invention, it is possible to prevent foreign objects from entering by filling the gap between the locking member and the cover member around the opening. Furthermore, according to the straddle-type seat of the present invention, it is possible to prevent foreign objects from entering even when the locking member is slid to release the lock. Furthermore, according to the straddle-type seat of the present invention, it is possible to make the operating section compact. Furthermore, according to the straddle-type seat of the present invention, when operating the operating part, it is possible to pinch and grasp the connecting part and the side wall with the fingers, improving operability. Furthermore, the straddle-type seat of the present invention enables the operator to intuitively understand the operating direction of the operating section. In addition, with the straddle-type seat of the present invention, when the backrest is moved, water is prevented from entering through the gap and getting the adjustment member wet, and by lengthening the upper side of the protective part, water is prevented from entering the mating portion between the adjustment member and the locking member even when the adjustment member is moved to the frontmost position. In addition, according to the straddle-type seat of the present invention, it is possible to properly seal the gap between the inner surface of the protective part and the outer surface of the pipe frame, thereby preventing water from entering the inside of the seat body. In addition, according to the straddle-type seat of the present invention, if the operating part is a bolt, a number of bolts are required equal to the number of adjustment members, and since there are multiple bolt receiving holes in the cover member, it is possible to reinforce weak parts between the bolt receiving holes and increase strength.

The motorcycle seat VS is detachably provided on the body VB of the motorcycle V, and Fig. 2 describes the motorcycle seat VS removed from the body VB.

[0020] The embodiment described below is merely an example for facilitating understanding of the present invention, and is not intended to limit the present invention. In other words, the shapes, dimensions, arrangements, and other aspects of the components described below may be modified or improved without departing from the spirit of the present invention, and the present invention naturally includes equivalents thereof.

[0021] In this specification, the terms indicating directions are defined as shown in Fig. 1 and Fig. 2. Specifically, in the following description, the "front-rear direction" means the front-rear direction as seen by a person sitting on the motorcycle seat VS. The "seat width direction" corresponds to the left-right direction as seen by a person sitting on the motorcycle seat VS. Furthermore, the "up-down direction" corresponds to the up-down direction as seen by a person sitting on the motorcycle seat VS.

[0022] <Main components of the VS motorcycle seat> A motorcycle seat VS according to this embodiment (hereinafter, motorcycle seat VS) is mounted on a motorcycle V by being attached to a vehicle body VB (motorcycle main body) as shown in Fig. 1. The motorcycle seat VS includes a seat main body S and a backrest B as main components.

[0023] 2 is an external view of a motorcycle seat VS, and for convenience of illustration, a part of the seat body S is shown with the cover material T removed to expose the cushion material C. Similarly, a part of the backrest B is shown with the cover material 22 removed to expose the cushion material 21.

[0024] (Seat body) The seat body S has a front seating portion S1 (front seat) on which the rider sits, and a rear seating portion S2 (rear seat) formed one step higher than the front seating portion S1 on which another rider sits. In other words, the motorcycle seat VS is a two-seater seat with the front seating portion S1 at the front and the rear seating portion S2 at the rear. The front seating portion S1 and the rear seating portion S2 are portions on which the buttocks and thighs of a rider (i.e., a seated person) of the motorcycle V rest. The seat body S is constructed by placing a cushioning material C on a bottom plate 10 described later, and covering the surface of the cushioning material C with a skin material T.

[0025] (Backrest B) A backrest B on which the driver leans is provided in a recessed step between the front seating portion S1 and the rear seating portion S2. The backrest B is movable relative to the seat body S, that is, configured so that it can be manually moved and adjusted in the front-rear direction.

[0026] The backrest B is configured by disposing a cushion material 21 on a backrest bottom 20 facing the step portion of the bottom plate 10 and covering the outside of the cushion material 21 with a skin material 22, which is fixed to the backrest bottom 20.

[0027] The backrest B is formed in a pillow shape with a concave front surface to cover the driver's waist. The lower surface of the backrest B is arranged on the rear upper surface of the front seating portion S1 so as to be movable in the front-rear direction. The upper surface of the backrest B is arranged so as to be continuous with the front upper surface of the rear seating portion S2.

[0028] 4 and 13 described later, a plate-like support frame 23 that is long in the left-right direction is fixed to the back surface of the backrest bottom 20 of the backrest B by a plurality of bolts and nuts (not shown). The front ends of a pair of pipe frames 24 that serve as mounting frames for the backrest B are welded to the left and right sides of the support frame 23.

[0029] The pair of pipe frames 24 are parallel to each other, pass through an opening in the bottom plate 10 and the cover material T of the seat body S, and are supported by a locking mechanism R described below so as to be movable in the front-rear direction. As described below, the backrest B is fixed by the locking operation of the locking mechanism R, and can be manually moved and adjusted in the front-rear direction by releasing the lock.

[0030] (Bottom plate 10) 3 shows a rear view of the motorcycle seat VS. A bottom plate 10, which constitutes the lower surface of the motorcycle seat VS, is made of a resin material. The bottom plate 10 has a front surface 11 and a back surface 12, and a pair of through holes 11a are formed between the front surface 11 and the back surface 12 of the bottom plate 10, through which a pair of pipe frames 24 (adjustment members) are inserted, respectively.

[0031] An accommodation recess 13 is formed in the approximate center in the seat width direction of the back surface 12 of the bottom plate 10, in which a lock plate 31 and a lock bracket 30 of a lock mechanism R, which will be described later, are accommodated. The accommodation recess 13 is a recess that is recessed in a direction from the back surface 12 toward the front surface 11 of the bottom plate 10 (i.e., upward). With the lock mechanism R accommodated in this accommodation recess 13, a lock cover 32, which will be described later, is attached.

[0032] A bag storage section 14 extending in the seat width direction is formed behind the storage recess 13. A storage bag 50, which will be described later, is placed in this bag storage section 14. The bag storage section 14 is a recess recessed in a direction from the back surface 12 toward the front surface 11 of the bottom plate 10 (i.e., upward). A front locking section 15a is formed in front of the bag storage section 14, and a rear locking section 15b is formed at the rear end of the bag storage section 14. The front locking section 15a is a cut-and-raised section formed to protrude forward, and the rear locking section 15b is a cut-and-raised section formed to protrude rearward.

[0033] Further, a front end of the accommodation recess 13 is formed with a plurality of engaging recesses 16 (engaged portions) into which the engaging claws 32d of the lock cover 32 fit and engage. As shown in Fig. 3, a striker 12a for attaching the motorcycle seat VS to the vehicle body VB is provided on the rear surface 12 of the bottom plate 10. The striker 12a may have a known structure that engages with a striker engaging portion (not shown) provided on the vehicle body VB.

[0034] <Lock mechanism R> Next, the structure of the lock mechanism R that adjusts and locks the position of the backrest B relative to the seat body S in multiple stages in the front-rear direction will be described with reference to Figs.

[0035] The lock mechanism R is supported integrally on the back surface 12 (lower surface) of the bottom plate 10, and comprises a lock bracket 30, a lock plate 31 slidably arranged in the left-right direction within the lock bracket 30, and a lock cover 32 covering the lock bracket 30 and the lock plate 31.

[0036] The lock bracket 30 is formed in a gate-shaped cross section and extends in the seat width direction. Guide tubes 34 are inserted and fixed into insertion holes 30a and 30b that open into the front and rear walls of the left and right sides.

[0037] 4, each guide tube 34 has engagement pieces 34a, 34b that engage with the insertion holes 30a, 30b protruding integrally from its outer circumferential surface. A pair of pipe frames 24 connected to the backrest B are slidably inserted through the pair of guide tubes 34. In this embodiment, the adjustment members are the pipe frames 24 serving as pillars.

[0038] 4, a plurality (three) of arc-shaped fitting slits 24a are formed at intervals in the axial direction on the outer surface of the middle portion of each pipe frame 24. A through hole 34c is formed on the outer periphery of the front portion of each guide tube 34, which selectively matches one of the fitting slits 24a.

[0039] The lock plate 31, which is provided on the lock bracket 30 so as to be slidable in the left-right direction, is formed in a plate shape, and long holes 31a opening at both ends thereof are pin-connected to both ends of the lock bracket 30 by connecting pins 33. The lock plate 31 is slidable in the left-right direction (seat width direction) relative to the lock bracket 30 within the length range of the long hole 31a. On the left and right sides of the lock plate 31, a pair of fitting holes 31b are opened which can be selectively fitted into one of the multiple fitting slits 24a of the pipe frame 24 through an opening 34c of the guide tube 34.

[0040] As shown in FIG. 10, a lock spring 35 made of a coil spring is stretched between the lock bracket 30 (more specifically, the spring locking portion 30c) and the lock plate 31 (more specifically, the spring locking portion 31c). This lock spring 35 urges the lock plate 31 in the locking direction (the direction of arrow a in FIG. 10, i.e., to the right) to selectively fit the fitting hole 31b of the lock plate 31 into one of the multiple fitting slits 24a through the through hole 34c, thereby locking the two pipe frames 24, i.e., the backrest B.

[0041] (Lock Plate 31) 5 to 10, the lock plate 31 is provided with an unlocking lever 31d that is integrally formed as an operating part at the lower end of a plate member that extends mainly in the seat width direction. The unlocking lever 31d has a bottom portion 31e that is disposed at the lower end, and a side wall 31f and a connecting portion 31g that are bent upward from the bottom portion 31e. In the seat width direction, the side wall 31f and the connecting portion 31g face each other, and the connecting portion 31g is formed to be longer in the up-down direction than the side wall 31f.

[0042] As shown in Fig. 9, the lock plate 31 has a bent portion 31h bent from a connecting portion 31g of the unlocking lever 31d. The bent portion 31h is a plate portion extending outward in the seat width direction from the upper end of the connecting portion 31g. As shown in Fig. 9, the unlocking lever 31d is connected to a protruding portion 31i of the plate member. In other words, a bottom portion 31e of the unlocking lever 31d is connected to the lower end of the protruding portion 31i that protrudes downward from approximately the center of the plate member extending in the seat width direction and the up-down direction.

[0043] (Lock Cover 32) The lock cover 32 (cover member) has a cover recess 32a recessed from the bottom to the top on its lower surface, and an opening 32b formed in the cover recess 32a. The opening 32b is disposed in the center of the lock cover 32 in the seat width direction. Both side portions of the cover recess 32a in the seat width direction are raised downward from the cover recess 32a, and a pair of guide tubes 34 and a pair of pipe frames 24 are housed therein.

[0044] Grease is applied to the surface of the pipe frame 24 to allow the pipe frame 24 to slide smoothly. As shown in FIG. 7, the lock cover 32 completely covers the pipe frame 24, and the pipe frame 24 cannot be seen when viewed from below or from the side of the motorcycle seat VS. More specifically, the lock cover 32 is formed with a pair of extension parts 32g that extend rearward in the moving direction of the pipe frame 24 (i.e., the front-rear direction). The pair of extension parts 32g have a bulging shape that protrudes downward. The pair of extension parts 32g overlap the pair of pipe frames 24 in the up-down direction, respectively. In other words, the pair of extension parts 32g are arranged so as to cover the pair of pipe frames 24 from below.

[0045] By covering the lock mechanism R including the pipe frame 24 with the lock cover 32, and in particular by completely covering the pipe frame 24 with the lock cover 32, it becomes possible to prevent grease from dripping downward and adhering to the vehicle body, etc. Furthermore, the presence of the lock cover 32 makes it possible to prevent grease from adhering to the operator's hands when the operator touches the pipe frame 24. In particular, by overlapping the pair of extension parts 32g with the pair of pipe frames 24 in the up-down direction, it becomes possible to appropriately cover the pipe frames 24, and therefore it becomes possible to prevent grease from dripping downward and adhering to the vehicle body, etc.

[0046] 5 and 7, the unlocking lever 31d (operation portion) protrudes downward and outward from an opening 32b formed in the lock cover 32. The unlocking lever 31d protrudes outward from the lock cover 32 and is provided in the center in the seat width direction. Here, the center in the seat width direction is the area between the pair of pipe frames 24 in the seat width direction, in other words, the area between the pair of guide tubes 34.

[0047] A plurality of engaging claws 32d are formed on the front end portion of the lock cover 32 to fit and engage with the engaging recesses 16 (engaged portions) of the accommodation recess 13. The engaging claws 32d are hook-shaped claws that protrude forward, and three of them are formed side by side in the seat width direction.

[0048] A pair of guide receiving portions 32e that sandwich and receive a pair of guide tubes 34 are formed on the back surface (upper surface) of the lock cover 32. Each guide receiving portion 32e is a pair of protrusions that protrude upward from the back surface of the lock cover 32.

[0049] The opening 32b has a notch 32f on the front left side (specifically, in the unlocking direction). The notch 32f has a depth capable of receiving the lock plate 31 when the lock plate 31 moves in the unlocking direction.

[0050] It is preferable to make the unlocking lever 31d (that is, the lock plate 31) and the lock cover 32 (cover member) different in color, since this makes it easier to recognize the unlocking lever 31d (operation portion).

[0051] (Regarding operation of the lock release lever 31d) 9 and 10, an operator operates the unlocking lever 31d provided at the lower end of the lock plate 31 to move the lock plate 31 in the unlocking direction (the direction of the arrow b in FIG. 11, i.e., the left direction). Specifically, when the operator moves the unlocking lever 31d in the unlocking direction, the lock plate 31 is moved in the unlocking direction (the direction of the arrow b in FIG. 10) against the biasing force of the lock spring 35, as shown in FIG. 11. At this time, the fitting hole 31b is disengaged from the fitting slit 24a of the pipe frame 24, and the backrest B can be moved and adjusted in the front-rear direction (unlocked state).

[0052] Then, when the operator releases the pulling force on the lock release lever 31d, the lock plate 31 is moved in the lock direction (the direction of arrow a in FIG. 10) by the biasing force of the lock spring 35 as shown in FIG. 10 and returned to the locked position, and the backrest B is fixed (locked state).

[0053] As described above, according to the motorcycle seat VS of this embodiment, the motorcycle seat VS is provided with a backrest B that is movable relative to the seat body S, and the backrest B has a pipe frame 24 (adjustment member) extending in the movement direction (front-rear direction) of the backrest B, and the seat body S has a bottom plate 10 through which the pipe frame 24 is inserted, a lock plate 31 (lock member) that prevents movement of the backrest B by abutting against the pipe frame 24, and a lock cover 32 (cover member) that covers the lock plate 31, and the lock plate 31 has an unlocking lever 31d (operation portion) that is operated when moving the backrest B, and the locking lever 31d protrudes outward from the locking cover 32 and is provided in the center in the seat width direction.

[0054] More specifically, the unlocking lever 31d protrudes downward and outward from an opening 32b formed in a cover recess 32a of the lock cover 32. With this configuration, the lock plate 31 is covered from below with the lock cover 32 to improve the appearance, while the lock plate 31 is directly moved by the unlocking lever 31d provided in the center in the seat width direction, making it possible to reduce the number of parts.

[0055] In addition, in the motorcycle seat VS, the lock cover 32 has a cover recess 32a recessed upward, the unlocking lever 31d is disposed inside the cover recess 32a in the seat front-rear direction, the seat width direction and the up-down direction, and the lowermost part of the unlocking lever 31d, i.e., the bottom part 31e, is positioned above the lowermost end of the area around the cover recess 32a of the lock cover 32 (FIG. 11). In other words, the bottom part 31e is positioned above the base end (fixed end) of the engaging claw 32d of the lock cover 32 (FIG. 11). With this configuration, the unlocking lever 31d does not protrude below the lowermost end of the lock cover 32, and can be disposed compactly.

[0056] The unlocking lever 31d also has a side wall 31f formed by bending from the bottom 31e at a position facing the connecting part 31g in the seat width direction (FIGS. 9 to 11). With this configuration, when operating the unlocking lever 31d, it is possible to pinch and grasp the connecting part 31g and the side wall 31f with fingers from the seat width direction, improving operability when unlocking.

[0057] Furthermore, the unlocking lever 31d protrudes downward and outward from an opening 32b formed in the lock cover 32, and the lock plate 31 has a bent portion 31h bent from the unlocking lever 31d, and the bent portion 31h is disposed so as to fill the gap between the unlocking lever 31d and the opening 32b when viewed from below the seat body S (i.e., the motorcycle seat VS) (FIGS. 6 and 11). With this configuration, by filling the gap between the lock plate 31 and the lock cover 32 around the opening 32b, it is possible to prevent foreign matter from entering the inside of the locking mechanism.

[0058] In addition, in a locked state in which movement of the backrest B is prevented, the length L1 of the portion where the bent portion 31h and the lock cover 32 overlap in the vertical direction is longer than the maximum movement amount L2 of the lock plate 31 (i.e., the lock release lever 31d) (FIG. 11). With this configuration, even when the lock release lever 31d of the lock plate 31 is slid to release the lock (unlocked state), it is possible to fill the gap between the lock plate 31 and the lock cover 32 around the opening 32b, thereby preventing foreign matter from entering.

[0059] The unlocking lever 31d has a bottom portion 31e extending in the seat width direction and a connecting portion 31g connecting the bottom portion 31e and the bent portion 31h, and the length of the bent portion 31h in the seat width direction is shorter than the length of the connecting portion 31g in the up-down direction (FIGS. 9 to 11). This configuration makes it possible to make the unlocking lever 31d compact.

[0060] (Protective member 40) 12 to 14, a protective member 40 is provided in front of a pair of through holes 11a formed in the bottom plate 10. The protective member 40 includes a ring-shaped peripheral portion 40a surrounding the outer periphery thereof and a cylindrical protective portion 40b provided in the center thereof. Note that in FIG. 13, the cover material T of the seat body S and the cover material 22 of the backrest B are omitted from illustration.

[0061] The protective member 40 has a ring-shaped peripheral portion 40a around its periphery, and water flowing forward from the rear seating portion S2 during rainfall can be guided from above to below along the outer periphery of the peripheral portion 40a. The peripheral portion 40a also makes it possible to prevent water from entering the periphery of the protective portion 40b. The peripheral portion 40a is inclined so that the lower end side is located further forward than the upper end side, so that water flowing forward from the rear seating portion S2 during rainfall can be more appropriately guided from above to below.

[0062] The pipe frame 24 is inserted into the protective portion 40b. The cylindrical protective portion 40b is formed so that the upper side is longer than the lower side. With this configuration, it is possible to prevent water from entering through the gap of the through hole 11a and wetting the pipe frame 24 when the backrest B is moved. In addition, by making the upper side of the protective portion 40b longer, water is prevented from entering the fitting portion between the pipe frame 24 and the lock plate 31 even when the pipe frame 24 is moved to the frontmost part (in the state shown in FIG. 14, the frontmost fitting slit 24a is arranged inside the protective portion 40b).

[0063] Moreover, the protective portion 40b has two waterproof ribs 40c protruding in a ring shape formed therein. By forming the protective member 40 from a resin material, the waterproof ribs 40c follow the movement of the pipe frame 24 even when the backrest B moves forward and backward or when a downward load is applied to the backrest B. With this configuration, the gap between the inner surface of the protective portion 40b and the outer surface of the pipe frame 24 is appropriately sealed, so that water is prevented from entering the inside of the seat body S, that is, the back surface 12 side of the bottom plate 10.

[0064] Furthermore, when the backrest B is positioned at the frontmost position (FIG. 14), each waterproof rib 40c is positioned forward of the frontmost fitting slit 24a. With this configuration, even when the backrest B (pipe frame 24) is moved to the frontmost position, water is prevented from entering through the fitting slit 24a of the pipe frame 24.

[0065] (50 storage bags) The motorcycle seat VS of this embodiment is capable of storing items such as tools on its back surface. As shown in Fig. 8, the storage bag 50 is a bag body that stores items therein. The storage bag 50 is stored in a rolled-up state in the bag storage portion 14, which is a recessed portion provided on the back surface 12 of the bottom plate 10.

[0066] In the seat width direction, a front engagement portion 15a serving as a hook is disposed between a pair of multiple pipe frames 24 (adjustment members), and a belt 51 is connected to a rear engagement portion 15b serving as a rear hook to support a storage bag 50.

[0067] The belt 51 has a front ring 51a at its front end and a rear ring 52a at its rear end. The front ring 51a is hooked to the front engagement portion 15a, and the rear ring 51b is hooked to the rear engagement portion 15b, so that the belt 51 supports the storage bag 50 in the bag housing portion 14.

[0068] <Modification> Although the configuration of a motorcycle seat VS according to one embodiment of the present invention has been described above, the above embodiment is merely an example for facilitating understanding of the present invention and is not intended to limit the present invention. In other words, the present invention can be modified and improved without departing from the spirit of the present invention, and of course, the present invention includes equivalents thereof.

[0069] In particular, the structure, material, shape, dimensions, etc. of each element constituting the motorcycle seat VS are not limited to those described in the above embodiment, and may be designed arbitrarily as long as it does not deviate from the spirit of the present invention.

[0070] The lock mechanism of the motorcycle seat according to the modified example will be described below with reference to Fig. 15 to Fig. 18. Fig. 15 is a schematic diagram for explaining the motorcycle seat according to the modified example, Fig. 16 is a cross-sectional view taken along line CC in Fig. 15, Fig. 17 is a rear view of the motorcycle seat according to the modified example, and Fig. 18 is a diagram showing a lock cover 150 attached to a bottom plate 110 of the motorcycle seat according to the modified example. In the following description, only the parts that differ from the above embodiment will be described.

[0071] A pair of through holes 111a, through which the pair of adjustment members 124 are respectively inserted, are formed between the front surface 111 and the back surface 112 of the bottom plate 110. In addition, a pair of nut attachment holes 111b, into which nuts 140 are attached, are provided behind the pair of through holes 111a.

[0072] As shown in Fig. 15, the front ends of a pair of adjustment members 124 serving as mounting frames for the backrest B are welded to the left and right sides of the support frame 123 of the backrest B. The pair of adjustment members 124 are parallel to each other, pass through through holes 111a opened in the bottom plate 110, and are supported by nuts 140 and bolts 141 serving as a locking mechanism (Figs. 16 and 17).

[0073] The pair of adjustment members 124 includes a plate portion 124a extending in the front-rear direction at the rear. The plate portion 124a has a plurality (three) of fitting holes 124b penetrating therethrough in the up-down direction (FIGS. 15 and 16).

[0074] Two adjustment members 124 are provided, and two bolts 141 are also provided as operating parts. When an operator operates the bolts 141 and removes them from the nuts 140, the plate parts 124a of the adjustment members 124 are released, and the backrest B can be freely moved in the front-rear direction (unlocked state). Then, when the backrest B is in a predetermined front-rear position, the operator inserts the bolts 141 into the corresponding fitting holes 124b and engages them with the nuts 140, thereby fixing the backrest B (locked state).

[0075] 17, the plate portion 124a is clamped in the seat width direction by the clamping portion 112a provided on the rear surface 112 of the bottom plate 110. With this configuration, when the backrest B is inserted into the through hole 111a, the position in the seat width direction is stable.

[0076] Further, an accommodating recess 113 for accommodating the plate portion 124a, the bolt 141, etc. is formed in approximately the center in the seat width direction of the back surface 112 of the bottom plate 110. The accommodating recess 113 is a recess that is recessed in a direction from the back surface 112 toward the front surface 111 of the bottom plate 110 (i.e., upward). With the plate portion 124a and the bolt 141 (part of the locking mechanism) received in this accommodating recess 113, the lock cover 150 is attached.

[0077] Lock cover 150 has ribs 151 as reinforcing parts between a pair of bolts 141. When the operating parts are bolts 141, the same number of bolts 141 as the adjustment members 124 are required, and lock cover 150 has a plurality of receiving holes (not shown) for bolts 141. This makes it possible to reinforce weak parts between the receiving holes for bolts 141 with ribs 151, thereby increasing strength.

[0078] The straddle-type seat according to the present embodiment has been described above as a vehicle seat mainly used for motorcycles. The straddle-type seat according to the present embodiment is not limited to vehicle seats for motorcycles, but can also be applied to, for example, snowmobiles, jet skis, three-wheeled buggies, or construction machinery seats.
