Description

  The present invention relates to a vehicle seat device that has a main seat and a sub-seat and is disposed in a vehicle.

  Conventionally, in a vehicle seat device, in order to be able to change the seat arrangement according to the number of passengers, in addition to a permanent main seat, a relatively small sub-seat that can be stored has been provided. Has been done.

For example, in the following Patent Document 1, in a vehicle seat device in which a sub seat is disposed on a side of a main seat, both the seat cushion and the seat back of the sub seat can be displaced below the same main seat. The sub-sheet is accommodated by providing a swing mechanism that supports the sub-sheet.
Japanese Patent Laid-Open No. 9-2113

  However, since the vehicle seat device described in Patent Document 1 has a configuration in which both the seat cushion and the seat back of the sub-seat are stored below the same main seat, the thickness of the seat cushion and the seat back of the sub-seat In order to secure the storage property of the sub-sheet, it must be thinned. For this reason, there is a problem that the rigidity of the sub-seat is insufficient and the seating property of the sub-seat is deteriorated.

  If a large storage space is secured below the main seat in which the sub-seat is stored, the thickness of the seat cushion and the seat back of the sub-seat can be increased to some extent. This increases the problem that the seating property of the main seat deteriorates.

  The present invention has been made in view of such problems, and an object of the present invention is to provide a vehicle seat device including a sub-seat that can be stored and has a good seating property.

  In order to solve the above problems, the present invention provides a vehicle seat device in which a sub-seat is disposed between a pair of left and right main seats that are spaced apart in the vehicle width direction. Each of the main seats includes a seat cushion and a seat back, and the sub seat includes a sub seat cushion and a sub seat back, and the sub seat cushion and the sub seat back each include the pair of main seats. A sub-seat use state disposed at a use position therebetween, the sub-seat cushion is stored below one of the pair of main seats, and the sub-seat back is stored below the other of the main seats The sub-sheet storage state is configured to be displaceable (claim 1).

  According to this vehicle seat device, the sub-seat having the sub-seat cushion and the sub-seat back and disposed between the pair of left and right main seats is between the sub-seat use state and the sub-seat storage state. The sub seat cushion is stored below one of the pair of main seats and the sub seat back is below the other of the main seat in the sub seat storage state. Since the sub-seat cushion and the sub-seat back are stored separately by being configured to be stored, the thickness of the two members can be reduced to a conventional vehicle seat device (sub-seat). Compared to the case of a seat device in which both the seat cushion and the sub seat back are stored under the same main seat) Even when the thickness extent that can be accommodated without problems sub sheet below the main seat. For this reason, the rigidity of the sub-seat can be sufficiently secured, and as a result, the seating property of the sub-seat can be improved.

  Here, there is no particular limitation on a specific mechanism for displacing the sub seat back between the storage position below the main seat and the use position above the sub seat back. A mechanism in which the sub-seat back is supported by the main seat in a state where it can be further erected by sliding in the vehicle width direction from the storage position is preferable.

  Further, a specific mechanism for configuring the sub seat cushion to be displaceable between a storage position below the main seat and a use position above the sub seat cushion is not particularly limited. A mechanism in which the sub seat cushion is supported by the main seat while being able to slide in the vehicle width direction from the storage position and further move upward is more preferable. A mechanism in which the sub seat cushion is supported by the main seat in a state in which the sub seat cushion can be slid forward in the vehicle width direction from the stowed position and then flipped up and down is preferable.

  Here, in a normal vehicle seat, the height dimension of the seat back including the headrest is often larger than the longitudinal length of the seat cushion, but when the sub-seat is to be formed in the same form as this There is a possibility that the sub seat back becomes large and cannot be stored under the main seat. Therefore, in the vehicle seat device of the present invention, the sub seat cushion and the sub seat back are divided at a position higher than the seat surface of the sub seat cushion, and the sub seat cushion is formed into the main seat cushion. It is preferable to include a cushion body disposed substantially in parallel and a rising portion that rises from the rear end portion of the cushion body along the main seat back and forms a backrest surface that is substantially continuous with the sub seat back ( Claim 5).

  According to this configuration, since the sub seat cushion and the sub seat back are divided at a position higher than the seat surface of the sub seat cushion, the height of the sub seat back generally tends to be larger than the sub seat cushion. Since the dimensions can be shortened, the sub-seat back can be stored compactly below the main seat. In this case, since the sub seat cushion is provided with a rising portion that rises along the main seat back, the sub seat cushion and the sub seat back form a substantially continuous backrest surface. The sitting comfort can be kept good.

  The said structure WHEREIN: It is preferable that the said sub seat cushion is comprised so that a displacement in the folding state by which the said standing part laid down toward the said cushion body was possible (Claim 6).

  According to this configuration, the sub seat cushion can be folded in a compact manner by causing the rising portion to lie down toward the cushion body and superimposing them, so that the sub seat cushion has a problem below the main seat. It can be stored without.

  As described above, according to the present invention, it is possible to provide a vehicle seat device that includes a sub-seat that can be stored and has a good seating property.

  Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 is a plan view showing an interior of a vehicle 10 in which the vehicle seat device of the present embodiment is employed. As shown in the figure, the vehicle 10 includes a front row seat row 1 including a driver seat 4 and a front passenger seat 5 and a rearmost seat row. A rear seat row 3 (so-called bench seat type) having an integral seat cushion and a seat back, and an intermediate seat row 2 positioned between the front seat row 1 and the rear seat row 3 It is installed. In addition, the member shown with the code | symbol 12 which exists in the both sides of the rear seat row | line | column 3 in a vehicle interior is the overhang | projection part of the wheel house for rear wheels.

  FIG. 2A is a perspective view showing the intermediate sheet row 2, and is a perspective view showing an embodiment of a vehicle seat device according to the present invention. As shown in FIG. 1 and FIG. 1 above, the intermediate seat row 2 is configured by a sub-seat 8 disposed between a pair of left and right main seats 6 and 7 that are spaced apart in the vehicle width direction. Has been. In the present specification, in the following description, when the main seat 6 that faces the front of the vehicle and is the right side of the pair of main seats 6 and 7 is specified and referred to as “the right main seat 6”, When the main seat 7 corresponding thereto is specified and indicated, it is referred to as a “left main seat 7”. In addition, “left” and “right” in this specification are always represented by the left and right when facing the front of the vehicle.

  2A, the right main seat 6 includes a main seat back 62 having a headrest 62a and a pair of left and right armrests 62b and c, and a main seat cushion 61, and is supported by a seat 63. Yes. One end of each of the armrests 62b, c is pivotally supported on both side surfaces of the main seat back 62, so that the other end protrudes forward (see the armrest 62b on the outer side in the vehicle width direction) and the main seat back. It is configured to be displaceable between the armrest storage state (see the armrest 62c on the inner side in the vehicle width direction) arranged along the side surface of 62.

  Similarly, the left main seat 7 includes a main seat back 72 having a headrest 72a and a pair of armrests 72b and c, and a main seat cushion 71, and is supported by a seat 73.

  Next, the structure of the seats 63 and 73 of the main seats 6 and 7 is shown in FIG. As shown in the figure, the seats 63 and 73 are provided on the lower surface of the main seat cushions 61 and 71 and the seat lower portion 24 slidably engaged with the pair of left and right vertical guide rails 20 extending in the vehicle longitudinal direction. A fixed upper part of the seat 22 and a pair of front and rear guide rails interposed between the upper part 22 of the seat and the lower part 24 of the seat, and these two members are connected so as to be relatively displaceable in the vehicle width direction. It comprises a guide rail 26. The vertical guide rail 20 is embedded in the vehicle body floor so that the passenger does not get in the way when walking on the vehicle body floor.

  Since the seats 63 and 73 have such a structure, the main seats 6 and 7 supported by the seats 63 and 73 are configured to be slidable in the vehicle front-rear direction and the vehicle width direction, respectively. That is, if the seat lower portion 24 moves back and forth along the vertical guide rail 20, the main seats 6 and 7 slide in the vehicle front-rear direction, and the seat upper portion 22 engaged with the lateral guide rail 26 becomes the seat lower portion 24. The main seats 6 and 7 slide in the vehicle width direction if they are displaced relative to the left and right.

  Returning to FIG. 2A again, the sub-seat 8 includes a sub-seat back 82 having a headrest 82a and a sub-seat cushion 81 constituted by a separate member independent of the sub-seat back 82. . The dividing surface (arrow A in the figure) between the sub seat cushion 81 and the sub seat back 82 is set at a position slightly higher than the seat surface of the sub seat cushion 81. For this reason, the sub seat cushion 81 is compared with the cushion main body 81a disposed substantially parallel to the main seat cushions 61 and 71 and the main seat backs 62 and 72 rising from the rear end portion of the cushion main body 81a. The rising portion 81b has a low target height, and the rising portion 81b forms a backrest surface that is substantially continuous with the sub seat back 82.

  The sub-seat 8 is configured to be housed below the main seats 6 and 7. Specifically, as shown in FIG. 2B, the sub seat cushion 81 is stored inside the seat 73 of the left main seat 7 (in the space formed below the seat upper portion 22 shown in FIG. 3). At the same time, the sub seat back 82 is accommodated in the seat 63 of the right main seat 6. From this, the sub seat 8 includes the sub seat cushion 81 and the sub seat back 82 which are separately stored below the main seats 6 and 7, respectively (the state shown in FIG. 2B), The sub-seat cushion 81 and the sub-seat back 82 are configured to be displaceable between the sub-seat use state (the state of FIG. 2A) disposed at the use position between the main seats 6 and 7, respectively. Yes. In the illustrated example, the sub seat cushion 81 is housed in the seat 73 of the left main seat 7 and the sub seat back 82 is housed in the seat 63 of the right main seat 6. The reverse is also possible.

  Next, each of the sub seat cushion 81 and the sub seat back 82 will be described in detail.

  First, the sub seat back 82 will be described. FIG. 4 shows that the sub seat back 82 is placed between the storage position (see FIG. 2B) in the seat 63 of the right main seat 6 and the use position (see FIG. 2A) above it. It is the figure which showed the mechanism for supporting so that a displacement is possible. As shown in FIG. 4, the sub seat back 82 is composed of a cylindrical guide 32 fixed inside the seat 63 of the right main seat 6 and a rod 34 inserted into the cylindrical guide 32. The sub-seat back rotating slide mechanism 30 is supported by the right main seat 6 so as to be slidable in the vehicle width direction and rotatable about the axis of the cylindrical guide 32. FIG. 4A shows a state in which the sub seat back 82 is pulled out from the inside of the seat 63 while being guided by the sub seat back rotating slide mechanism 30. The sub seat back 82 can be pulled out through a gap formed between the upper portion 22 and the lower portion 24 of the seat 63 in the seat 63 shown in FIG. This is the same when the operation of pulling out a sub seat cushion 81 described later from the seat 73 is performed.

  The sub seat back 82 further includes two cylindrical members 38 provided therein, and two support shafts 40 protruding from the rod 34 and inserted into the cylindrical member 38. The rod 34 is supported by the right main seat 6 through a sub-seat back slide mechanism 36 so as to be slidable in the radial direction of the rod 34. FIG. 4B shows a state in which the sub seat back 82 is pulled outward in the radial direction of the rod 34 while being guided by the sub seat back slide mechanism 36. The support shaft 40 includes a large diameter portion 40b having a slightly smaller diameter than the cylindrical member 38 and a small diameter portion 40a having a diameter smaller than the large diameter portion 40b and fixed to the rod 34. The cutout portion 32a for inserting the small diameter portion 40a of the support shaft 40 is formed in the cylindrical guide 32 of the sub-seatback rotary slide mechanism 30.

  FIG. 5 is a perspective view showing the shape of the back surface of the sub seat back 82. As shown in the drawing, two concave portions 82 b are formed in the back surface portion of the sub seat back 82. This is because the sub-seat back 82 is disposed between the main seat backs 62 and 72 on the inner side surface in the vehicle width direction of the main seat backs 62 and 72 when the sub-seat is in use (the state shown in FIG. 2A). The attached armrests 62c and 72c are for avoiding interference with the back surface portion of the sub seat back 82.

  FIG. 6 is a schematic view showing a locking device for locking the sub seat back 82 to the main seat backs 62 and 72. In the drawing, a locking device for locking the sub seat back 82 to the right main seat 6 side (main seat back 62) will be described, but the same applies to the left main seat 7 side.

  6 includes a latch 102 supported in a recess 108 provided in a side surface portion of a main seat back 62, and a pin fixed in a recess 110 provided in a side surface portion of a sub seat back 82. 106. A claw portion 102 a that engages with the pin 106 is formed on one end side of the latch 102, and a latch shaft 102 b is fixed to the other end side of the latch 102. The latch shaft 102 b is fitted into a long hole 104 that penetrates from the recess 108 to the back surface of the main seat back 62. An operation lever (not shown) for operating the latch 102 is provided on the back surface of the main seat back 62, and this operation lever is directly connected to the latch shaft 102b. Therefore, by operating this operation lever, the latch shaft 102b can be rotated or slid in the left-right direction along the elongated hole 104, whereby the latch 102 is unlocked as shown in FIG. The state can be displaced to the locked state shown in FIG. Specifically, from the unlocked state shown in FIG. 6 (a), the latch 102 is rotated to insert the latch 102 into the recess 110 on the sub seat back 82 side (FIG. 6 (b)). If it is slid to the seat back 62 side, the claw portion 102a of the latch 102 can be engaged with the pin 106 and displaced to the locked state shown in FIG. In addition, the latch 102 may be stably held at the locked position or the unlocked position by providing reduced diameter portions at the left and right ends of the long hole 104.

  Next, the sub seat cushion 81 will be described. FIG. 7 shows that the sub seat cushion 81 is placed between the storage position (see FIG. 2B) of the left main seat 7 in the seat 73 and the upper use position (see FIG. 2A). It is the figure which showed the mechanism for supporting so that a displacement is possible. As shown in the figure, the sub seat cushion 81 is composed of a cylindrical guide 44 fixed inside the seat 73 of the left main seat 7 and a rod 46 inserted into the cylindrical guide 44. It is supported by the left main seat 7 via a seat cushion rotation slide mechanism 42 so as to be slidable in the vehicle width direction and rotatable about the axis of the cylindrical guide 44. FIG. 7 shows a state where the sub seat cushion 81 is pulled out from the inside of the seat 73 while being guided by the sub seat cushion rotating slide mechanism 42. Further, as can be seen from this drawing, the sub seat cushion 81 is folded in such a manner that the rising portion 81b shown in FIG. 2A (using the sub seat) lies down toward the cushion body 81a. In addition, the cushion body 81a is stored inside the seat 73 with the top and bottom turned upside down. The cushion body 81a and the rising portion 81b are connected by a hinge fitting 55, whereby the sub seat cushion 81 is configured to be foldable.

  The sub seat cushion 81 further includes two guide rails 52 fixed to the back surface of the cushion main body 81a, and two engagement members protruding from the rod 46 and slidably engaged with the guide rails 52. It is supported by the left main seat 7 through a sub-seat cushion slide mechanism 48 composed of a joint member 50 so as to be slidable in the tangential direction of the rod 46. Although not shown for convenience of drawing, the cylindrical guide 44 has a notch for inserting the engaging member 50 formed in the same manner as the notch 32a (FIG. 4). Yes.

  Similarly, as shown in FIG. 7, two concave portions 181 b are formed on the back surface of the rising portion 81 b of the sub seat cushion 81. This is because the sub-seat cushion 81 is disposed between the main seat cushions 61 and 71 in the sub-seat use state (the state shown in FIG. 2A), the support shaft 40 that supports the sub-seat back 82 (see FIG. 2). 4) is for avoiding interference with the back surface of the rising portion 81b. Further, two claw members 54 that are engaged with the rod 34 (FIG. 4) that supports the sub-seat back 82 are provided on the back surface of the cushion body 81a when the sub-seat is used.

  Next, the sub seat cushion 81 and the sub seat back 82 configured as described above are placed between the main seats 6 and 7 from a state where the sub seat cushion 81 and the sub seat back 82 are stored below the main seats 6 and 7 (sub seat storage state). The procedure for displacing to the state of being disposed (sub-sheet usage state) will be described with reference to FIGS.

  First, the procedure for disposing the sub seat back 82 will be described with reference to FIG.

  First, the armrests 62c and 72c provided on the inner surfaces in the vehicle width direction of the main seats 6 and 7 are jumped up along the main seat backs 62 and 72 (FIG. 8A).

  Next, the sub seat back 82 housed in the seat 63 of the right main seat 6 is pulled inward in the vehicle width direction. Accordingly, the sub seat back 82 is pulled out to the outside of the seat 63 (between the seats 63 and 73) while being guided by the sub seat back rotating slide mechanism 30 (FIG. 4).

  Next, the sub seat back 82 is pulled forward of the vehicle. As a result, the sub seat back 82 moves to an appropriate position toward the front of the vehicle while being guided by the sub seat back slide mechanism 36 (FIG. 4) (FIG. 8B).

  Next, the sub seat back 82 is pulled up obliquely rearward and upward. As a result, the sub seat back 82 rises with the rod 34 of the sub seat back rotating slide mechanism 30 (FIG. 4) as the center of rotation, and the sub seat back 82 is disposed between the main seat backs 62 and 72. . At this time, since the concave portion 82b is provided on the back surface portion of the sub seat back 82 as described above, the armrests 62c and 72c provided on the inner side surfaces in the vehicle width direction of the main seat backs 62 and 72 are provided in the concave portion. Therefore, the interference between the armrests 62c and 72c and the sub seat back 82 is effectively avoided. Then, after the arrangement of the sub seat back 82 is completed as described above, the sub seat back 82 is locked between the main seat backs 62 and 72 by operating the locking device 100 shown in FIG.

  Next, the procedure for disposing the sub seat cushion 81 will be described with reference to FIG.

  First, after the operation of disposing the sub seat back 82 is completed (FIG. 9A), the sub seat cushion 81 housed in the seat 73 of the left main seat 7 is moved inward in the vehicle width direction. pull. Thereby, the sub seat cushion 81 is pulled out to the outside of the seat 73 (between the seats 63 and 73) while being guided by the rotary slide mechanism 42 for the sub seat cushion (FIG. 7).

  Next, the sub seat cushion 81 is pulled forward of the vehicle. Accordingly, the sub seat cushion 81 moves to an appropriate position toward the front of the vehicle while being guided by the slide mechanism 48 for the sub seat cushion (FIG. 7) (FIG. 9B).

  Next, the sub seat cushion 81 is pulled up obliquely rearward and upward. As a result, the sub seat cushion 81 is inverted with the rod 46 of the sub seat cushion rotating slide mechanism 42 (FIG. 7) as the center of rotation, and the sub seat cushion 81 is disposed between the main seat cushions 61, 71. The At this time, since the claw member 54 is provided on the back surface of the cushion main body 81a of the sub seat cushion 81, the claw member 54 is engaged with the rod 34 that supports the sub seat back 82. Therefore, the sub seat cushion 81 is stably fixed and held (locked) between the main seat cushions 61 and 71. In order to engage the claw member 54 with the rod 34 as described above, the sub seat cushion 81 is slightly slid forward in the vehicle at the time of FIG. 9B, and the sub seat cushion 81 is inverted. Then, the sub seat cushion 81 may be pulled back in the direction in which the claw member 54 is engaged.

  Finally, when the rising portion 81b of the folded sub seat cushion 81 is raised, the arrangement of the sub seat cushion 81 is completed, and as a result, the sub seat 8 as shown in FIG. 2A is formed. Is done. At this time, since the recess 181b (FIG. 7) is formed on the back surface of the rising portion 81b as described above, the support shaft 40 that supports the sub seat back 82 is accommodated in the recess 181b. Therefore, interference between the support shaft 40 and the rising portion 81b is effectively avoided. In order to stably hold the rising portion 81b between the main seatbacks 62 and 72, the width dimension of the rising portion 81b is slightly larger than the gap size formed between the main seatbacks 62 and 72. Just keep it. By doing so, the rising portion 81b can be held stably by being sandwiched between the main seatbacks 62 and 72 (usually made of a soft material such as urethane) and elastically deformed.

  If the intermediate sheet row 2 configured as described above is used, the sub-sheet 8 can be freely displaced between the stored state and the used state, and after the sub-sheet 8 is stored, Various seat arrangements are also possible. Hereinafter, the seat arrangement after storing the sub-seat 8 will be described.

  FIG. 10 shows a state where both the right main seat 6 and the left main seat 7 are slid inward in the vehicle width direction from the state in which the sub seat 8 is stored (the state in FIG. 2B), or FIG. 6 is a perspective view showing a state of the intermediate sheet row 2 when only one of the right main seat 6 and the left main seat 7 is slid and brought close to another one. As shown in the figure, when the right main seat 6 and the left main seat 7 are brought close to each other, the pair of main seats 6 and 7 form a substantially continuous seating surface. It can be arranged like a so-called bench seat. In the present embodiment, the armrests 62c and 72c on the inner side in the vehicle width direction are attached in a state of protruding from the side surfaces in the vehicle width direction of the main seatbacks 62 and 72. However, a gap is formed between the right main seat 6 and the left main seat 7, but a recess is provided on the inner side surface in the vehicle width direction of each main seat back 62, 72, and the armrests 62c, 72c are provided in the recess. Since the armrests 62c and 72c do not interfere with each other, it is possible to form a substantially complete bench seat.

  FIG. 11A shows the situation in the passenger compartment when the intermediate seat row 2 is arranged like a bench seat as described above. As shown in this figure, when the seat arrangement is performed, the main seats 6 and 7 are close to each other, so that the side wall of the vehicle body 10 is compared with the case where the sub seat 8 is used (the state of FIG. 1). And the gap between the main seats 6 and 7 widen. Then, a person who tries to get into the rear seat row 3 from the rear door on the side of the intermediate seat row 2 can easily get into the rear seat row 3 through the enlarged gap (illustrated). Arrow B). Therefore, if the intermediate seat row 2 is arranged like a bench seat, the boarding / exiting property to the rear seat row 3 can be improved. FIG. 11 (a) shows an example in which both the main seats 6 and 7 are slid inward in the vehicle width direction and are collected near the center in the vehicle width direction. Of course, it is also possible to bring the intermediate sheet row 2 to one side in the vehicle width direction by sliding only one of them. In this case, if the left main seat 7 is slid to approach the right main seat 6, a considerably wide gap can be formed on the left side of the intermediate sheet row 2. Getting in (from the left rear door) can be greatly facilitated.

  In addition, as shown in FIG. 11A, when both the main seats 6 and 7 are slid inward in the vehicle width direction and collected near the center in the vehicle width direction, 11 is within the region sandwiched between the overhanging portions 12 of the wheel house that protrudes into the vehicle interior, so that the main seats 6 and 7 avoid the overhanging portion 12 as shown in FIG. It becomes possible to slide largely backward from the state of (a). FIG. 11B shows a state where the main seats 6 and 7 are slid as described above. As shown in the figure, if the main seats 6 and 7 are largely slid to the position close to the rear seat row 3 while avoiding the overhanging portion 12, the vast space between the front seat row 1 and the intermediate seat row 2 is increased. Space can be secured.

  Here, when the main seats 6 and 7 are slid in the longitudinal direction of the vehicle in this way, if the right main seat 6 and the left main seat 7 are configured to slide together in an integrated manner, one-touch operation is possible. It is convenient to move both at the same time. In addition, since the relative positions in the front-rear direction of the right main seat 6 and the left main seat 7 always coincide with each other, when the sub-seat 8 is disposed again between the main seats 6, 7, the main seat 6, There is also an advantage that it is not necessary to match the relative position in the front-rear direction. In order to integrally slide the right main seat 6 and the left main seat 7 in the vehicle front-rear direction, for example, the seat lower portion 24 in the seat 63 of the right main seat 6 shown in FIG. What is necessary is just to comprise so that the pedestal lower part 24 in the pedestal 73 of 7 may be integrally connected by a predetermined | prescribed connection member.

  As described above, according to the vehicle seat device (intermediate seat row 2) of the present embodiment, the sub seat cushion 81 and the sub seat back 82 are disposed between the pair of left and right main seats 6 and 7. The provided sub-seat 8 is configured to be displaceable between the sub-seat use state and the sub-seat storage state. In the sub-seat storage state, the sub-seat cushion 81 has the main seats 6 and 7 One of them (the left main seat 7 in this embodiment) is stored below, and the sub seat back 82 is stored below the other of the main seats 6 and 7 (the right main seat 6 in this embodiment). Since the sub-seat cushion 81 and the sub-seat back 82 are separately housed by being configured as described above, Even if the thickness of the two members is made somewhat thicker than in the case of a conventional vehicle seat device (a seat device that houses both the sub seat cushion and the sub seat back under the same main seat), the sub seat 8 Can be stored below the main seats 6 and 7 without problems. For this reason, the rigidity of the sub seat 8 can be sufficiently secured, and as a result, the seating property of the sub seat 8 can be improved.

  In addition, by storing the sub seat cushion 81 and the sub seat back 82 separately in the right main seat 6 and the left main seat 7, the rod 34 supporting the sub seat back 82 extends from the right main seat 6, Since the rod 46 supporting the sub seat cushion 81 extends from the left main seat 7, the load of the occupant when the occupant sits on the sub seat cushion 81 supported by both the rods 34 and 46 is The main seat 6 and the left main seat 7 can be dispersed and supported. Further, since the main seats 6 and 7 are integrally connected via the sub-seat 8, there is an advantage that the seating property of the sub-seat 8 can be further improved.

  In the present embodiment, the dividing surface A (FIG. 2) between the sub seat cushion 81 and the sub seat back 82 in the sub seat 8 is set higher than the seating surface of the sub seat cushion 81. May be set at the same height as the seating surface of the sub seat cushion 81. However, in such a setting, the height dimension of the sub seat back 82 including the headrest 82 a becomes considerably large, and there is a possibility that the sub seat back 82 cannot be stored below the right main seat 6. Conversely, if the height of the sub seat back 82 is suppressed by omitting the headrest 82a or the like, even if the dividing surface A is set to the same height as the seat surface of the sub seat cushion 81, there is no problem. The seat back 82 can be stored.

  In the present embodiment, the sub seat cushion 81 and the sub seat back 82 are configured to be displaced from the storage position to the use position (or vice versa) while being guided by the sub seat back rotating slide mechanism 30 or the like. Such a mechanism is not always necessary. For example, the sub-seat cushion 81 and the sub-seat back 82 are stored under the main seats 6 and 7 in a state where the sub-seat cushion 81 and the sub-seat back 82 can be taken out freely. It may be arranged between the sheets 6 and 7. Conversely, the sub-seat back rotary slide mechanism 30 or the like may be configured to be automatically driven by using a motor, various gears, or the like.

  In the present embodiment, the rod 46 that supports the sub seat cushion 81 and the rod 34 that supports the sub seat back 82 are supported by the left main seat 7 and the right main seat 6 in a cantilevered state. However, the rods 34 and 46 can be supported by supporting the rods 34 and 46 by supporting the rods 34 and 46 in the protruding state so that the tip ends thereof are supported by the opposite sheet (supported in a state where both ends are supported). The rigidity may be further increased.

  In the present embodiment, the sub seat cushion 81 and the sub seat back 82 are placed inside the seats 63 and 73 having the shape as shown in FIG. 3 (in the space formed under the seat upper portion 22). Although it is configured to be accommodated, the sub seat cushion 81 or the sub seat back 82 is not limited to such a configuration as long as the sub seat cushion 81 or the sub seat back 82 can be stored and taken out. You may make it do. In that case, similarly to the above-mentioned Patent Document 1, the main seat cushions 61 and 71 may be configured to be openable and closable, and the sub seat cushion 81 and the like may be taken in and out therefrom.

  In the present embodiment, the locking device 100 including the latch 102 and the pin 106 is used as a device for locking the sub seat back 82 to the main seat backs 62 and 72. However, the sub seat back 82 can be locked. If it is, not only such a locking device 100 but various locking devices can be used. For example, the lock device may be configured by providing pins that protrude toward the sub seat back 82 in the main seat backs 62 and 72 and providing holes in the sub seat back 82 into which the pins are inserted. Further, the sub seat back 82 may be locked by providing a stopper on the sub seat back rotating slide mechanism 30 that supports the sub seat back 82.

  In the present embodiment, the armrests 62b, c and the like are provided on the main seatbacks 62, 72. However, the armrests may be omitted if not particularly necessary. In that case, the recessed part 82b provided in the back surface part of the sub seat back 82 can be omitted. However, even when the armrest is provided, for example, if the material of the back portion of the sub seat back 82 is rich in elasticity and has a sufficient deformation allowance, the concave portion 82b can be omitted.

  In the present embodiment, both the main seats 6 and 7 are configured to be slidable in the vehicle front-rear direction and the vehicle width direction. However, if not particularly necessary, such a slide mechanism may be omitted, A slide mechanism may be provided on only one of the sheets 6 and 7.
