Fig. 10 shows the X-X section of fig. 9.

Fig. 1 shows a slide seat 10 to which a wiring structure 1 for a slide seat of the present embodiment is applied. The slide seat 10 is disposed in the vehicle 100. The slide seat 10 is a rear seat in the vehicle 100, and is, for example, a third seat from the front. As shown in fig. 9 and the like, the wiring structure 1 for a slide seat of the present embodiment is a wiring structure for electrically connecting a vehicle body side of a vehicle 100 and a slide seat 10 with a wire harness 2. The wire harness 2 has, for example, a cylindrical exterior member and a plurality of electric wires accommodated inside the exterior member. The plurality of electric wires include, for example, a power supply line and a signal line.

As shown in fig. 1, a vehicle 100 has an interior 5. The interior 5 is a member constituting a side wall of a vehicle cabin in the vehicle 100. The interior 5 is fixed to the inner surface side with respect to the vehicle body panel, for example. The interior 5 may be a resin molded member. The interior 5 extends along the vehicle front-rear direction X and the vehicle up-down direction H. The interior 5 is supported by, for example, the floor member 102.

The slide seat 10 of the present embodiment is configured to be slidable in the vehicle longitudinal direction X. The slide seat 10 has a slide body 7, a seat cushion 8, a seat back 9, and a slider 11. The vehicle 100 has a rail 101 that guides the slider 7. The rail 101 is disposed outside the vehicle with respect to the interior 5, and is fixed to the vehicle body. The rail 101 extends along the vehicle front-rear direction X. The slider 7 is slidably supported by the rail 101. That is, the slider 7 is supported by the vehicle body of the vehicle 100 so as to be slidable in the vehicle longitudinal direction X. The slider 11 is slidably supported by a rail of the floor member 102.

The slide seat 10 of the present embodiment is configured to be able to spring up the seat cushion 8. The seat cushion 8 is coupled to the slider 7 so as to be rotatable relative to the slider 7. The rotation axis of the seat cushion 8 is along the vehicle front-rear direction X. Fig. 2 shows a slide seat 10 in which the seat cushion 8 is sprung. In the following description, the state in which the seat cushion 8 is sprung up in the slide seat 10 will be simply referred to as "sprung up state". In the slide seat 10, a state in which an occupant can sit on the seat cushion 8 is simply referred to as an "extended state". In the unfolded state, the seat surface of the seat cushion 8 faces upward in the vehicle up-down direction H, and the seatback 9 stands up.

When the seat cushion 8 is sprung, first, the seat back 9 falls down, and the seat back 9 is integrated with the seat cushion 8. Thereafter, the seat cushion 8 and the seatback 9 stand up toward the interior member 5. The seat cushion 8 is rotated relative to the slider 7, and the slide seat 10 is thereby brought into the sprung state. In the sprung state, the back surface of the seat back 9 faces the interior material 5. In the sprung state, the back surface of the seat back 9 may also be in contact with the interior 5.

The slider 7 has a slider 70 shown in fig. 3 and a handrail 73 shown in fig. 4. As shown in fig. 3, the slider 70 has a main body 71 and a pair of support portions 72, 72. The main body 71 is slidably supported by the rail 101. The interior 5 has an opposing portion 5a that opposes the rail 101 in the vehicle vertical direction H. The opposed portion 5a is formed with a through hole 50. The through hole 50 penetrates the opposing portion 5a in the plate thickness direction. The through hole 50 has a width through which the main body 71 can be inserted, and extends along the vehicle longitudinal direction X. The main body 71 protrudes from the through hole 50 toward the vehicle upper side.

The support portion 72 protrudes upward from the main body 71. The pair of support portions 72, 72 face each other in the vehicle longitudinal direction X. The support portion 72 has a support hole 72a formed therein. The support hole 72a is a recess or hole formed along the vehicle front-rear direction X. The support hole 72a rotatably supports the rotation shaft of the seat cushion 8. Bearings for supporting the rotation shaft of the seat cushion 8 may be provided in the support holes 72a.

The interior 5 has a groove-like recess 51 extending in the vehicle front-rear direction X. The concave portion 51 is recessed toward the opposite side opposite to the slide body 7 side. In other words, the concave portion 51 is recessed toward the vehicle outside in the vehicle width direction Y. The recess 51 is arranged corresponding to the movement range of the slider 70. The concave portion 51 faces the support portion 72 in the vehicle width direction Y. That is, the rotation axis of the seat cushion 8 faces the recess 51. The recess 51 is provided with an opening 52 for drawing the wire harness 2. The opening 52 communicates a space on the vehicle inner side of the interior material 5 and a space on the vehicle outer side of the interior material 5 in the vehicle width direction Y. The armrest 73 is connected to the slider 70. The armrest 73 covers the slider 70 from, for example, the upper side in the vehicle vertical direction H.

As shown in fig. 1 and the like, the winding device 3 is disposed on the vehicle outside with respect to the interior 5. The winding device 3 is disposed, for example, at a position facing the recess 51. The winding device 3 is fixed with respect to the vehicle body of the vehicle 100. As shown in fig. 5, the winding device 3 includes a main body 30, a cylindrical portion 31, and a lead-out portion 32. The main body 30, the cylindrical portion 31, and the lead-out portion 32 are formed of, for example, insulating synthetic resin.

The main body 30 is a frame body accommodating the wire harness 2. The shape of the main body 30 is, for example, a cylindrical shape with both ends in the axial direction closed. A winding mechanism for winding the wire harness 2 is disposed inside the main body 30. The winding mechanism includes, for example, a rotating body around which the wire harness 2 is wound and a spring. The winding device 3 can wind the wire harness 2 and draw out the wire harness 2 by a winding mechanism.

The cylindrical portion 31 is formed in a cylindrical shape and extends from the main body 30. The opening 31a of the tubular portion 31 is open in the vehicle width direction Y. The wire harness 2 is led out from the inside of the main body 30 through the cylindrical portion 31. The winding device 3 is disposed so that the opening 31a faces the opening 52 of the interior material 5. Therefore, the wire harness 2 led out from the opening 31a is inserted through the opening 52 in the vehicle width direction Y. The lead-out portion 32 is an outlet portion for leading out the electric wire on the vehicle body side. The electric wire on the vehicle body side is electrically connected to the wire harness 2 inside the main body 30. The electric wire on the vehicle body side is led out from the lead-out unit 32 and connected to a power supply and a control device.

As shown in fig. 6, the holding member 4 is disposed on the slider 7. The holding member 4 is a member that holds the wire harness 2 and moves along the vehicle front-rear direction X together with the slider 7. The holding member 4 of the present embodiment is fixed to the armrest 73. A part of the holding member 4 protrudes from the side surface 73a of the armrest 73 in the vehicle width direction Y. The wire harness 2 is inserted into the inner space of the armrest 73 via the holding member 4, and is held by the holding member 4.

As shown in fig. 7 and 8, the holding member 4 has a main body 40 and a cover 41. The main body 40 and the cover 41 are formed of, for example, insulating synthetic resin. As shown in fig. 8, the main body 40 has a bottom wall 42, a first side wall 43, and a second side wall 44. The bottom wall 42, the first side wall 43 and the second side wall 44 are formed as one body. A passage 45 of the wire harness 2 is formed by the bottom wall 42, the first side wall 43 and the second side wall 44. The bottom wall 42 is a wall portion that supports the wire harness 2 from below.

The first side wall 43 and the second side wall 44 stand up from the edge portion of the bottom wall 42, and face each other in the vehicle front-rear direction X. The first side wall 43 has a straight portion 43a and a curved portion 43b. The linear portion 43a extends linearly in the vehicle width direction Y. The base end 43c of the curved portion 43b is connected to the straight portion 43 a. The curved portion 43b is curved away from the second side wall 44 as going from the base end 43c toward the tip end 43d of the curved portion 43b.

The second side wall 44 has a straight portion 44a and a curved portion 44b. The linear portion 44a extends linearly in the vehicle width direction Y. The linear portion 44a is opposed to the linear portion 43a of the first side wall 43, and is parallel to the linear portion 43 a. The base end 44c of the bent portion 44b is connected to the straight portion 44 a. The bent portion 44b is bent away from the first side wall 43 as going from the base end 44c toward the tip end 44d of the bent portion 44b.

In this way, the first side wall 43 and the second side wall 44 have tapered shapes in which the distance between the curved portions 43b and 44b is increased toward the distal ends 43d and 44d of the curved portions 43b and 44b. Therefore, the width of the duct 45 increases toward the one end 45a in the vehicle width direction Y.

The cover 41 is engaged with the main body 40 to cover the passage 45 from above. The cover 41 has a covering portion 46 and an engaging portion 47. The cover portion 46 and the engaging portion 47 are integrally formed. The covering portion 46 is a portion that covers the passage 45 from above. The cover portion 46 has a rectangular portion 46a and a tapered portion 46b. The rectangular portion 46a is substantially rectangular in shape in plan view. The rectangular portion 46a is formed to cover a range from the linear portion 43a of the first side wall 43 to the linear portion 44a of the second side wall 44.

The shape of the tapered portion 46b in plan view is a tapered shape that expands in width as it moves away from the rectangular portion 46a in the vehicle width direction Y. The tapered portion 46b is formed to cover a range from the bent portion 43b of the first side wall 43 to the bent portion 44b of the second side wall. The engagement portion 47 engages with the main body 40 to fix the cover 41 to the main body 40. The cover 41 has a holding portion 49 that holds the wire harness 2. The holding portion 49 protrudes from the cover portion 46 in the vehicle width direction Y.

The holding member 4 has a cylindrical portion 48 formed by the main body 40 and the cover 41. As shown in fig. 7, the width W1 of the tubular portion 48 in the vehicle longitudinal direction X increases toward the opening 48a along the vehicle width direction Y. The wire harness 2 is inserted through the cylindrical portion 48 and held by the holding member 4. The wire harness 2 is fixed to the holding portion 49 by a belt or a strap member, for example. That is, the holding portion 49 holds the wire harness 2 via a belt or a strap member. The wire harness 2 may be held by being sandwiched between the bottom wall 42 of the main body 40 and the rectangular portion 46a of the cover 41. In this case, at least one of the bottom wall 42 and the cover 41 may have a protrusion or rib for pressing the wire harness 2.

The holding member 4 is disposed such that the opening 48a faces the recess 51 of the interior material 5. That is, the tubular portion 48 is disposed such that the width W1 of the vehicle longitudinal direction X increases as approaching the interior 5 in the vehicle width direction Y. The shape of the cylindrical portion 48 is a curved shape that does not cause excessive bending stress to the wire harness 2.

Fig. 9 to 11 show the slide seat 10 and the wire harness 2 in the unfolded state. The position of the slide seat 10 shown in fig. 9 and the like is the rearmost position in the vehicle front-rear direction X in the movable range. In the following description, the position of the slide seat 10 is referred to as the rearmost position of the movable range simply as the "rear end position", and the foremost position of the movable range simply as the "front end position". At the rear end position, as shown in fig. 10, the holding member 4 faces the opening 52 in the vehicle width direction Y. That is, in the vehicle width direction Y, the opening 52 is coaxial with the cylindrical portion 48 of the holding member 4. The tip 48b of the holding member 4 is located on the same surface as the wall surface 5b of the interior component 5. Therefore, the holding member 4 can shield the wire harness 2 from the occupant, and the wire harness 2 can be made inconspicuous.

As shown in fig. 9 to 11, the wire harness 2 led out from the winding device 3 is inserted through the interior component 5 toward the cabin. As shown in fig. 9, the interior material 5 has a cylindrical portion 53 protruding in the vehicle width direction Y. The cylindrical portion 53 protrudes toward the cylindrical portion 31 of the winding device 3. The opening 52 is provided at the tip of the cylindrical portion 53. The shape of the cylindrical portion 53 in plan view is a tapered shape in which the width in the vehicle longitudinal direction X becomes smaller as it goes toward the cylindrical portion 31 in the vehicle width direction Y.

As shown in fig. 10, the wire harness 2 is led out from the opening 52 toward the vehicle cabin via the recess 51. The wire harness 2 penetrating the interior member 5 is inserted into the cylindrical portion 48 of the holding member 4, and is further disposed in a space inside the armrest 73. As shown in fig. 9, the end of the wire harness 2 is fixed to a fixing portion 80 of the seat cushion 8. Each wire of the harness 2 is connected to equipment disposed in the slide seat 10. The ends of the wires may also be connected to connectors. In this case, each wire is connected to the device of the slide seat 10 via a connector.

As shown in fig. 9, the wiring path of the wire harness 2 in the slide seat 10 is curved. In more detail, the wire harness 2 has a first portion 21, a second portion 22, and a bent portion 23. The first portion 21 is a portion extending in the vehicle width direction Y from the holding member 4 toward the seat cushion 8. The second portion 22 is a portion that extends in the vehicle front-rear direction X and is fixed to the seat cushion 8. The bend 23 connects the first portion 21 and the second portion 22.

The holding member 4 holds the first portion 21 such that the first portion 21 extends in the vehicle width direction Y. As shown in fig. 11, the first portion 21 of the present embodiment extends parallel to the vehicle width direction Y. The fixing portion 80 holds the second portion 22 such that the second portion 22 extends along the vehicle front-rear direction X. The fixing portion 80 is disposed, for example, in front of the vehicle with respect to the first portion 21. In this case, the second portion 22 extends from the bent portion 23 toward the vehicle front. The second portion 22 of the present embodiment extends parallel to the vehicle front-rear direction X.

As shown in fig. 9, when the slide seat 10 is in the unfolded state, the curved portion 23 has a substantially circular arc shape in plan view. The shape of the bent portion 23 is determined so as not to cause excessive bending stress to each wire of the wire harness 2.

In fig. 12, the slide chair 10 is shown in a front position. When the slide seat 10 slides forward in the vehicle front-rear direction X, the holding member 4 moves forward together with the armrest 73. The holding member 4 moves forward while holding the wire harness 2, and draws the wire harness 2 from the winding device 3. The drawn wire harness 2 extends along the vehicle front-rear direction X inside the recess 51 of the inner 5. Therefore, it is difficult for the wire harness 2 drawn out from the occupant to be seen, and the wire harness 2 is less likely to interfere with the armrest 73 or the like.

As shown in fig. 12, a first portion 26 and a second portion 27 are formed in the wire harness 2. The first portion 26 and the second portion 27 are formed between the slide seat 10 and the opening 52 of the interior part 5. The first portion 26 is a portion protruding from the cylindrical portion 48 toward the recess 51 in the vehicle width direction Y. The second portion 27 is a portion extending in the recess 51 along the vehicle front-rear direction X. A bend 28 is formed between the first portion 26 and the second portion 27. The wire harness 2 of the present embodiment has the first portion 26, and follows the movement of the slide seat 10 while forming the second portion 27.

The second portion 27 of the present embodiment extends in the recess 51 from a position 51a of the recess 51 facing the tubular portion 48 to the opening 52. As a mechanism for extending the second portion 27 in the recess 51, for example, the holding member 4 holds the wire harness 2. In the holding member 4, the wire harness 2 projects the cylindrical portion 48 toward the recess 51. The holding member 4 holds the wire harness 2 so as to press the wire harness 2 against the bottom surface 51b of the recess 51. The wire harness 2 pressed toward the bottom surface 51b forms the second portion 27 and the bent portion 28, and extends in the recess 51.

As a means for extending the second portion 27 in the recess 51, a curved portion 53a is provided in the tubular portion 53 of the inner material 5. The curved portion 53a is curved so as to expand the width of the cylindrical portion 53 as approaching the slide seat 10 in the vehicle width direction Y. A bending portion 29 that is bent along the bending portion 53a is formed in the wire harness 2. The bent portion 53a of the cylindrical portion 53 guides the wire harness 2 inserted from the opening portion 52 to the bottom surface 51b. Accordingly, the second portion 27 of the wire harness 2 can extend along the bottom surface 51b.

When the slide seat 10 slides rearward, the winding device 3 winds the surplus length of the wire harness 2. That is, the winding device 3 applies tension to the wire harness 2 extending in the recess 51. Thus, the wire harness 2 can follow the movement of the slide seat 10 in a state where the second portion 27 is extended in the recess 51.

Fig. 13 and 14 show the slide seat 10 and the wire harness 2 in the sprung state. The slide seat 10 of the present embodiment is configured to be able to spring up at the rear end position. As shown in fig. 13, in the sprung state, the fixed portion 80 of the seat cushion 8 is located above the first portion 21 in the vehicle up-down direction H. That is, the seat cushion 8 rotates relative to the slider 70 so that the fixed portion 80 moves upward relative to the first portion 21.

When the seat cushion 8 is sprung, the fixing portion 80 moves upward while bending the first portion 21 of the wire harness 2. As a result, the second bending portion 24 is formed in the first portion 21. That is, in the sprung state, the wire harness 2 is formed with the second bending portion 24 in addition to the bending portion 23. The wiring structure 1 for a slide seat is preferably configured so that stress in the axial direction of the harness 2 is less likely to occur when the slide seat is sprung. For example, the rotation mechanism for rotating the seat cushion 8 is preferably configured such that tensile stress is less likely to occur in the first portion 21 when the seat cushion 8 rotates. For example, at least one of the armrest 73 and the seat cushion 8 may also have a space portion that allows bending deformation of the wire harness 2. For example, a space portion may be provided around a portion where the second bending portion 24 is formed so as not to restrict the wire harness 2.

The above-described wiring structure 1 for a slide seat can make the wire harness 2 follow the movement of the slide seat 10 in the vehicle longitudinal direction X. Further, the wiring structure 1 for a slide seat can make the wire harness 2 follow the bounce of the seat cushion 8. Thus, the wiring structure 1 for a slide seat can make the wire harness 2 follow the slide seat 10 with the pop-up mechanism appropriately.

Further, by providing the wire harness 2 with the bent portion 23, bending load on each wire of the wire harness 2 can be reduced. By providing the wire harness 2 with the bent portion 23, torsion of the wire harness made up of a plurality of electric wires is allowed when the second bent portion 24 is formed. As a result, bending load of each wire is reduced as compared with the case where the wire harness 2 does not have the bending portion 23.

As described above, the wiring structure 1 for a slide seat according to the present embodiment includes: a recess 51 provided in the interior 5 constituting the side wall of the vehicle cabin; an opening 52 disposed in the recess 51; a cylindrical portion 48; a wire harness 2; and a winding device 3. The recess 51 extends in the vehicle front-rear direction X, and is recessed toward the vehicle outside. The opening 52 communicates a space on the vehicle outside of the interior 5 with a space on the vehicle inside of the interior 5.

The cylindrical portion 48 is arranged in the slide seat 10 that slides in the vehicle front-rear direction X along the interior 5. The cylindrical portion 48 faces the recess 51 and opens to the recess 51. The wire harness 2 is inserted from the opening 52 through the recess 51 into the cylindrical portion 48, and is connected to the slide seat 10. According to the wiring structure 1 for the slide seat according to the present embodiment, the wiring harness 2 is routed in the recess 51, so that the wiring harness 2 is less likely to interfere with the slide seat 10.

The wire harness 2 of the present embodiment has the first portion 26 protruding from the tubular portion 48 toward the recess 51 in the vehicle width direction Y, and follows the movement of the slide seat 10 while forming the second portion 27 extending in the recess 51 in the vehicle front-rear direction X. For example, in the present embodiment, the wire harness 2 is held by the holding member 4. The wire harness 2 protrudes from the cylindrical portion 48 toward the recess 51 in the vehicle width direction Y, and is bent toward the vehicle front-rear direction X by abutting against the bottom surface 51b of the recess 51. Thereby, the first portion 26 protruding from the cylindrical portion 48 toward the recess 51 and the second portion 27 extending in the recess 51 along the vehicle front-rear direction X are formed.

The second portion 27 of the present embodiment extends in the recess 51 from a position 51a of the recess 51 facing the tubular portion 48 to the opening 52. Therefore, the wire harness 2 can be made less likely to interfere with the slide seat 10.

The slide seat 10 of the present embodiment has an armrest 73 facing the recess 51. The cylindrical portion 48 is fixed to the armrest 73. By disposing the concave portion 51 at a position opposed to the armrest 73, the concave portion 51 is covered with the armrest 73 and is not easily visible.

The distal end 48b of the cylindrical portion 48 of the present embodiment protrudes from the slide seat 10 toward the recess 51. According to this structure, the path of the wire harness 2 is stable, and the wire harness 2 is not easily pulled out from the recess 51 to the outside.

The shape of the tubular portion 48 of the present embodiment is a tapered shape in which the width W1 in the vehicle longitudinal direction X increases as it goes toward the recess 51 in the vehicle width direction Y. This can reduce the bending load applied to the wire harness 2.

First modification of the embodiment

A first modification of the embodiment will be described. Fig. 15 is a perspective view of a wiring structure for a slide seat according to a first modification of the embodiment, and fig. 16 is a plan view of a wiring structure for a slide seat according to a first modification of the embodiment. In the first modification of the embodiment, the point different from the above embodiment is that, for example, the winding device 3 is disposed in the slide seat 10.

As shown in fig. 15 and 16, the wiring structure 1 for a slide seat according to the first modification of the embodiment includes: a recess 51 provided in the inner component 5; an opening 52 disposed in the recess 51; a cylindrical portion 6 disposed on the slide seat 10; a wire harness 2; and a winding device 3.

The winding device 3 is disposed on the seat cushion 8 of the slide seat 10. The winding device 3 may be accommodated inside the seat cushion 8. The wire harness 2 protrudes from the winding device 3 in the vehicle width direction Y. The winding device 3 is capable of winding the wire harness 2 and extracting the wire harness 2.

The cylindrical portion 6 is a cylindrical member, and is disposed in the slide seat 10. The tubular portion 6 faces the recess 51 in the vehicle width direction Y, and opens toward the recess 51. The shape of the cylindrical portion 6 is a tapered shape in which the width in the vehicle longitudinal direction X increases as it goes toward the concave portion 51 in the vehicle width direction Y. The wire harness 2 of the first modification is not fixed to the cylindrical portion 6. In other words, the cylindrical portion 6 does not hold the wire harness 2, and can freely pass the wire harness 2.

An opening 52 is disposed in the recess 51. The opening 52 is disposed, for example, in the center of the recess 51 in the vehicle longitudinal direction X. The slide seat 10 is configured to be able to spring up the seat cushion 8 at a position where the tubular portion 6 faces the opening 52.

The wire harness 2 is inserted from the opening 52 through the recess 51 into the cylindrical portion 6, and is connected to the slide seat 10. As shown in fig. 16, the interior component 5 has a holding member 55. The holding member 55 is disposed in the opening 52. The holding member 55 has a cylindrical portion 56 and a holding portion 57. The cylindrical portion 56 and the holding portion 57 are formed of, for example, insulating synthetic resin.

The cylindrical portion 56 is cylindrical in shape and extends in the vehicle width direction Y. One end of the cylindrical portion 56 opens to the opening portion 52. The wire harness 2 is inserted from the opening 52 to the tubular portion 56 along the vehicle width direction Y. The holding portion 57 protrudes from the other end of the cylindrical portion 56. The wire harness 2 is fixed to the holding portion 57 by a belt or a strap member. The wire harness 2 led out from the cylindrical portion 56 is connected to a power source and a control device.

As with the wire harness 2 of the above embodiment, the wire harness 2 of the first modification follows the movement of the slide seat 10 in the vehicle longitudinal direction X. The wire harness 2 is formed in the second portion 27 extending in the recess 51 and follows the movement of the slide seat 10. For example, in the case where the slide seat 10 is moved toward the rear end position, as shown in fig. 12, the wire harness 2 forms the second portion 27 from the holding member 55 toward the vehicle rear. The second portion 27 extends in the recess 51 along the vehicle front-rear direction X. The winding device 3 sends out the wire harness 2 or winds the wire harness 2 in accordance with the movement of the slide seat 10.

Second modification of the embodiment

A second modification of the embodiment will be described. Fig. 17 is a cross-sectional view of a wiring structure for a slide seat according to a second modification of the embodiment. In the second modification of the embodiment, the point of difference from the above-described embodiment is that the tip 48b of the cylindrical portion 48 is inserted into the recess 51.

As shown in fig. 17, the tip 48b of the cylindrical portion 48 of the second modification is located inside the recess 51. That is, the distal end 48b of the tubular portion 48 moves in the vehicle longitudinal direction X in the inner space of the recess 51. With this structure, the wire harness 2 is less likely to come out of the recess 51. Further, the first portion 26 of the wire harness 2 is covered with the cylindrical portion 48, whereby the wire harness 2 is less noticeable. In the wiring structure 1 for a slide seat according to the first modification, the tip 6a of the tubular portion 6 may be inserted into the recess 51.

Third modification of the embodiment

The shape and arrangement of the holding member 4 and the cylindrical portion 6 are not limited to the exemplified shape and arrangement. For example, the slide seat 10 may not have the bouncing mechanism. In this case, the holding member 4 and the cylindrical portion 6 may be disposed on the seat cushion 8. The recess 51 of the interior 5 may be provided at a position opposed to the seat cushion 8.

The above-described embodiments and modifications can be appropriately combined and executed.
