Description

  The present invention belongs to a technical field related to a vehicle seat device including a plurality of seats arranged in a vehicle width direction on a floor panel forming a floor of a vehicle compartment of a vehicle.

  Conventionally, in a seat device disposed just before the cargo compartment at the rear of the vehicle, it is possible to place a load on the back of the seat back by lying the seat back on the seat cushion on the seat cushion well known. In addition, in the seat device, when the seat back is lying down, the height of the back of the seat back at the time of lying down is lowered by moving the seat cushion downward in conjunction with the lying down. A so-called dive-down seat device is also known (see, for example, Patent Document 1). Such a seat device is composed of a plurality (usually two or three) of seats arranged side by side in the vehicle width direction, and each of the seats can be independently stored. This makes it possible to arrange seats according to the number of passengers, the size of luggage, and the like.

JP-A-2005-247318

  By the way, in the above-mentioned seat device, normally, when the seat backs of all the seats are in an upright state, the seating surfaces of all the seat cushions are set at substantially the same height position, and the backrest surfaces of all the seat backs are in the seat longitudinal direction. It is set at substantially the same position.

  However, in the seat device, the thickness of at least one of the seat cushion and the seat back in the plurality of seats may be different between the plurality of seats. For example, when the seat device includes two seats arranged in the vehicle width direction, the armrest can be stored in the seat back of the seat including the portion corresponding to the center in the vehicle width direction of the passenger compartment. In this case, the thicknesses of the seat backs of the two sheets are different from each other. In such a case, if the seat cushions of all the seats are moved downward by the same amount, there is a high possibility that the heights of the backs of the seat backs in the lying state of the seats do not match. In particular, when the heights of the backs of the seat backs of at least two seats continuous in the vehicle width direction do not match, there is a possibility that a step is generated between the seat backs of the seats and the usability of the backs of the seat backs is deteriorated. is there.

  The present invention has been made in view of such a point, and an object of the present invention is to provide a vehicle seat device including a plurality of seats, and to improve the usability of the back surface of the seat back in a lying state in the plurality of seats. It is in trying to improve.

  In order to achieve the above object, according to the present invention, a plurality of seats each having a seat cushion and a seat back disposed so as to be arranged in the vehicle width direction on a floor panel forming a floor of a vehicle compartment of a vehicle. , For a vehicle seat device including a plurality of seat cushion support portions that respectively support the seat cushions of the plurality of seats on the floor panel, the seat backs of the plurality of seats are each in an upright state, It is configured to be switchable to a lying state lying on a seat cushion corresponding to the seat back, and the plurality of seats are different from each other in the thickness of at least one of the seat cushion and the seat back. Yes, a seat cushion support part excluding one of the plurality of seat cushion support parts, or all seat cushion support parts Has an interlocking mechanism that moves the seat cushion downward in conjunction with switching from the standing state of the seat back corresponding to the seat cushion to the lying down state, and in the vehicle width direction among the plurality of seats. The seat cushion in which the seat cushion support portion has the interlocking mechanism among the at least two seats continuous to each other, and the amount of downward movement of the seat cushion by the interlocking mechanism is in the lying state of the at least two seats It was set as the back surface of was set so that it might be located in the substantially same height position.

  With the above configuration, by appropriately setting the amount of downward movement of the seat cushion by the interlocking mechanism, the back surface of the seat back in the lying state of at least two seats continuous in the vehicle width direction is positioned at substantially the same height position. It is possible to improve the usability of the back surface of the seat back. In addition, it is not necessary to configure all the at least two seats so that they can be stored in a dive down manner. The sheet is normally stored without dive-down storage, and the other sheets are stored in the dive-down storage, and the height position of the back of the seat back in the lying state of the sheet to be stored in the dive-down is determined. By appropriately setting the amount of downward movement of the seat cushion by the interlocking mechanism of the seat cushion support portion that supports the seat cushion, the seat back is normally placed in a lying position on the back of the seat back. You just have to match. By normally storing one sheet in this way, it becomes possible to reduce the cost and weight of the sheet apparatus as compared with a case where all sheets can be stored in a dive-down manner.

  In the vehicle seat, at least one of at least two seats continuous in the vehicle width direction is a seat adjacent to the side wall portion of the vehicle compartment, and the seat of the seat adjacent to the side wall portion of the vehicle compartment. It is preferable that at least one of the cushion and the seat back be formed with a side support portion that is bulged from a seating surface of the seat cushion or a backrest surface of the seat back on the vehicle width direction outer side.

  This makes it possible to hold the occupant so as not to roll against the centrifugal force generated when the vehicle bends. On the other hand, such a side support portion increases the possibility that the thickness of at least one of the seat cushion and the seat back of the seat adjacent to the side wall portion of the passenger compartment is different from that of the seat adjacent to the seat. However, in the present invention, even if the thicknesses are different as described above, the height position of the seat adjacent to the side wall portion of the passenger compartment and the back surface of the seat back of the seat adjacent to the seat can be substantially the same height. As a result, the usability of the back of the seat back can be improved.

  In the vehicle seat, one of at least two seats that are continuous in the vehicle width direction is a specific seat that includes a portion corresponding to a center portion in the vehicle width direction of the vehicle compartment, and the specific seat The seat cushion support portion that supports the seat cushion has the interlocking mechanism, the seat back of the specific seat has an armrest at a portion corresponding to the vehicle width direction center portion of the vehicle compartment, and the armrest is A retracted state in which one surface of the armrest stored in the seatback forms a part of a backrest surface of the seatback, and a use state that protrudes forward from the seatback and can be used as an armrest It is preferable that it is configured to be switchable.

  As a result, even if the seat back becomes thick in order to store the armrest in the seat back of the specific seat, the specific seat is dive-down stored, so the back of the seat back in the lying state in the specific seat By properly setting the height position, the amount of downward movement of the seat cushion by the interlocking mechanism of the seat cushion support portion that supports the seat cushion of the specific seat, the seat adjacent to the specific seat is in a lying state It can be made substantially the same as the height position of the back surface of the seat back.

  In the vehicle seat, the plurality of seats are two seats that are continuous in the vehicle width direction, one side seat adjacent to one of the side wall portions of the vehicle compartment and the other side seat adjacent to the other. The width of the seat cushion of the one side seat is preferably larger than the width of the seat cushion of the other side seat, and the width of the seat back of the one side seat is preferably larger than the width of the seat back of the other side seat.

  As described above, when the vehicle seat includes two seats having different widths of the seat cushion and the seat back, the one side seat having a large width includes a portion corresponding to the center in the vehicle width direction of the passenger compartment. The retractable armrest is provided in the portion of the seat back of the one side seat, the retractable child seat is provided in a portion different from the portion of the seat cushion of the one side seat, etc. There is a high possibility that the thickness of the seat back is different between the one-side sheet and the other-side sheet, so that the operational effects of the present invention can be effectively exhibited. In the case of storing both seats in a dive-down manner, the amount of downward movement of both seat cushions by the interlocking mechanism of the seat cushion support portions that respectively support the seat cushions of both seats is set appropriately. The backs of the seat backs of both sheets are positioned at substantially the same height. In addition, when one of the two seats is normally stored and the other one is stored in the dive down state, it is assumed that the two seats are not stored in the dive down state. The seat with the higher position is stored in the dive down position, and the amount of downward movement of the seat cushion is appropriately set by the interlocking mechanism of the seat cushion support part that supports the seat cushion of the seat that is stored in the dive down position. By doing so, the height of the back surface of the seat back in the lying state in the seat that is normally stored is adjusted.

  In the vehicle seat, all of the plurality of seat cushion support portions may have the interlocking mechanism.

  Accordingly, it is easy to position the back surface of the seat back in the lying state of at least two seats continuous in the vehicle width direction at substantially the same height position, and the back surface of the seat back in the lying state of all the seats. The height of the bag can be made as low as possible, and the load amount of the luggage on the back of the seat back can be increased.

  In the vehicle seat, one seat cushion support portion of the plurality of seat cushion support portions may be configured such that the seat back of the seat back with respect to the floor panel in a lying state of the seat back corresponding to the seat cushion. It is preferable that the seat cushion support portion is configured by a support member that is supported at the same position as the standing state, and the remaining seat cushion support portion has the interlocking mechanism.

  As a result, the cost and weight of the sheet apparatus can be reduced as compared with a case where all sheets can be stored in a dive-down manner.

  In the vehicle seat, an article storage section for storing articles formed in a box shape opening upward is provided below the seat cushion supported by the seat cushion support section configured by the support member. It is preferable.

  In other words, the seat cushion supported by the seat cushion support portion formed by the support member does not move downward, so that an empty space exists below the seat cushion. This empty space can be used effectively as an article storage unit. Further, the article can be stored inside the article storage portion so as not to obstruct the passenger's seating, and the convenience of the passenger can be improved.

  The vehicle seat is disposed immediately before the cargo compartment of the vehicle, and when the seat backs of all the plurality of seats are in a lying state, the back of all the seat backs is the floor of the cargo compartment. It is preferable that it is located in the substantially same height position.

  Thereby, the utility of a vehicle compartment and a luggage compartment can be improved, and the effect of this invention can be exhibited effectively.

  As described above, according to the vehicle seat device of the present invention, even if the thickness of at least one of the seat cushion and the seat back in the plurality of seats is different between the plurality of seats, all the seats in the lying state Usability of the backs of the seat backs can be improved by making the backs of the backs substantially the same height.

As a result, the left seat back 7 pivots around the pivot shaft 7h from the standing state in which the occupant can sit on the left seat 2 (the state shown in FIG. 2), and on the left seat cushion 6. It is possible to switch to the lying down lying state (the state shown in FIG. 3).

  A back plate 7i is provided at the rear portion of the seat back frame 7g of the left seat back 7 so as to cover the frame-shaped opening of the seat back frame 7g. A pair of left and right armrest support members 7j are attached and fixed near the upper side of the rotation shaft 7h in the back plate 7i so as to be positioned on both sides of the armrest 35. The armrest support member 7j supports the lower end portion of the armrest 35 in the retracted state so as to be rotatable around a shaft 7k extending in the seat width direction. Thereby, the armrest 35 can be switched between a retracted state (a state indicated by a solid line in FIG. 2) and a use state (a state indicated by a two-dot chain line in FIG. 2).

  The left seat cushion 6 is supported on the floor panel 21 by the left seat cushion support portion 23. The left seat cushion support portion 23 includes a front support portion 23 a that supports the front portion of the left seat cushion 6 on the floor panel 21 and a rear support portion that supports the rear portion of the left seat cushion 6 on the floor panel 21. 23b. That is, in the left seat cushion 6, a seat cushion frame 6f formed in a substantially rectangular frame shape is disposed along the front surface, the rear surface, and both side surfaces of the left seat cushion 6, and the seat cushion frame 6f. The front end portions of the both side portions are supported by the front support portion 23a, and the rear end portions of the both side portions of the seat cushion frame 6f are supported by the rear support portion 23b.

  The front support portion 23a includes a pair of left and right left seat cushion support brackets 24 attached and fixed across the first floor portion 21a and the kick-up portion 21b of the floor panel 21 on the lower side of the left seat cushion 6, and The left seat cushion support bracket 24 is attached and fixed to a pair of left and right rotating members 25 supported so as to be rotatable about a shaft 27 extending in the seat width direction, and front end portions on both side portions of the seat cushion frame 6f. And a pair of left and right mounting members 26. Each rotating member 25 is connected to each mounting member 26 so as to be rotatable around an axis 28 extending in the sheet width direction. When the left seat back 7 is in the standing state, the rotating member 25 extends in the vertical direction, and the shaft 28 is positioned substantially directly above the shaft 27.

  The rear support portion 23b includes a pair of left and right connecting members 29 that connect the seat cushion frame 6f and the seat back frame 7g, and the left seat cushion 6 via the seat back frame 7g and the left seat back support bracket 22. The rear portion (the rear end portions on both side portions of the seat cushion frame 6f) is supported with respect to the floor panel 21. One end portions of the pair of connecting members 29 are fixedly attached to the rear end portions on both side portions of the seat cushion frame 6f, while the other end portions of the rotation shafts 7h on the both side portions of the seat back frame 7g.

The right seat cushion support portion 41 has a different configuration from the left seat cushion support portion 23 and does not have the interlocking mechanism as described above. That is, the right seat cushion support portion 41 supports the right seat cushion 11 at the same position as the standing state of the right seat back 12 with respect to the floor panel 21 when the right seat back 12 is lying down. For this reason, even if the right seat back 12 is laid down, the right seat cushion 11 does not move in conjunction with the laying down (it is not stored in the dive down).

  Specifically, the right seat cushion support portion 41 includes a support member 42 that is fixed to the kick-up portion 21 b of the floor panel 21 and supports the right seat cushion 11. As shown in FIG. 6, the support member 42 has an article storage portion 42a formed in a rectangular parallelepiped box shape opening upward. On the other hand, an inverted dish-shaped seat cushion pan 15 whose entire peripheral edge protrudes downward is fixed to the lower end portion of the right seat cushion 11, and this seat cushion pan 15 opens the opening of the article storage portion 42a. It is placed on the support member 42 so as to close it. In this way, the right seat cushion 11 is supported on the floor panel 21 by the right seat cushion support portion 41 (support member 42). Thus, the article storage portion 42a is provided below the right seat cushion 11. The article storage portion 42a is not always necessary. Further, the article storage portion 42a may be formed of a member different from the support member 42 that supports the central seat cushion 11.

  Through holes 15 a are respectively formed in the front side portions on both sides in the seat width direction at the peripheral edge of the seat cushion pan 15. In addition, rotation shafts 42b that are fitted into the through holes 15a are fixed to the side surfaces of the article storage portion 42a on both sides in the sheet width direction. Thereby, the seat cushion pan 15 (the right seat cushion 11) is configured to be rotatable around the rotation shaft 42b. When the article is taken into and out of the article storage portion 42a, when the right seat back 12 is in the standing state, the rear end portion of the right seat cushion 11 is lifted and the right seat cushion 11 is rotated. By rotating counterclockwise in FIG. 4 around the shaft 42b, the opening of the article storage portion 42a is opened.

  Since the right seat cushion 11 does not move downward in conjunction with the fall of the right seat back 12, the right seat cushion 11 is positioned higher than the left seat cushion 6 in the lying state of the left seat back 7 and the right seat back 12. (See FIGS. 5 and 7). Further, since the right seat cushion 11 does not move to the front side in conjunction with the fall of the right seat back 12, the right seat cushion 11 is not positioned on the rotation locus of the right headrest 13. In the lying state, the right headrest 13 does not contact the front end portion of the seating surface 11a of the right seat cushion 11, and the side support portion 12b of the right seat back 12 contacts the side support portion 11b of the right seat cushion 11.

  In the present embodiment, when the left seat back 7 and the right seat back 12 are lying down, the left seat cushion 6 by the interlocking mechanism is so positioned that the back surfaces (upper surfaces) of both the seat backs 7 and 12 are located at substantially the same height. The amount of downward movement is set. That is, it is assumed that the thickness of the left seat back 7 (the thickness of the central portion 7a) is larger than the thickness of the right seat back 12 (the thickness of the side support portion 11b) and the left seat cushion 6 does not move downward. The back surface of the left seat back 7 in the lying state is positioned higher than the back surface of the right seat back 12 in the lying state. In practice, however, the left seat cushion 6 moves downward, and the amount of movement is set so that the back surface of the left seat back 7 is positioned at substantially the same height as the back surface of the right seat back 12. Therefore, the back surface of the left seat back 7 and the back surface of the right seat back 12 are positioned at substantially the same height position (see FIGS. 5, 7, and 8). Thereby, the back surface of the left seat back 7 and the right seat back 12 in the lying state forms a continuous surface over the entire vehicle width direction. In addition, the rear end portions of the rear surfaces of the left seat back 7 and the right seat back 12 in the lying state are substantially at the same height as the upper surface of the floor member 73. In the present embodiment, the back surfaces of the left seat back 7 and the right seat back 12 in the lying state are almost horizontal, and substantially the entire back surface (except for the front end portion that originally protrudes) is substantially the same as the top surface of the floor member 73. It can be said that they are at the same height. In addition, the back surface of the left seat back 7 and the right seat back 12 in the lying state may be at a height position different from the upper surface of the floor member 73, and in this case, at a height position lower than the upper surface of the floor member 73. Preferably there is.

  The left seat back 7 and the right seat back 12 define a compartment 71 and a cargo compartment 72 when in a standing state. Since the seat backs 7 and 12 can be independently put into a lying state, various seat arrangements are possible depending on the number of passengers, the size of the luggage loaded in the luggage compartment 72, and the like. The utility of the chamber 72 is improved. In the lying state of the left seat back 7 and the right seat back 12, the backs of both the seat backs 7, 12 are positioned at substantially the same height (form a continuous surface), so the left seat back in the lying state 7 and the usability of the back surface of the right seat back 12 are improved. In addition, since the back surfaces of the left seat back 7 and the right seat back 12 in the lying state are substantially at the same height as the top surface of the floor member 73, a large luggage having a particularly large width is not lifted on the floor member 73 without lifting. It is possible to place them on the back surfaces of both seat backs 7 and 12 while sliding.

  Further, since the left seat 2 and the right seat 3 are configured so that only the left seat 2 can be dive-down stowed, the cost and weight can be reduced as compared with the case where both the sheets 2 and 3 are configured to be dive-down stowable. it can.

  In the above-described embodiment, only the left seat 2 of the left seat 2 and the right seat 3 is configured to be dive-down accommodated, but both the sheets 2 and 3 may be configured to be dive-down retractable. In this case, the right seat cushion support part 41 also has an interlocking mechanism similar to the interlocking mechanism of the left seat cushion support part 23. However, when the left seat back 7 and the right seat back 12 are lying down, both seat backs 7 , 12 may be set such that the amount of movement of the left seat cushion 6 and the right seat cushion 11 to the lower side by each interlocking mechanism is set so that the back surfaces of the left and right seat cushions 11 are located at substantially the same height position (the lower side of the left seat cushion 6). The amount of movement to the right is greater than the amount of movement of the right seat cushion 11 to the lower side). If both the seats 2 and 3 are configured so that they can be dive-down stored in this way, the backs of the seat backs 7 and 12 can be placed at substantially the same height at a lower position. It is possible to increase the amount of luggage loaded on top.

  Moreover, in the said embodiment, although the thickness (thickness of the center part 7a) of the left seat back 7 was made larger than the thickness of the right seat back 12 (thickness of the side support part 12b), in addition to this or it replaces with this Assuming that the thickness of the left seat cushion 6 is larger than the thickness of the right seat cushion 11, the back surfaces of both the seat backs 7 and 12 are substantially the same height when the left seat back 7 and the right seat back 12 are lying down. Only the left seat 2 or both the seats 2 and 3 may be configured so as to be dive-down accommodated so as to be positioned in the vertical position. For example, when a retractable child seat is provided in the side portion 7 b of the left seat cushion 6, the side portion 7 b of the left seat cushion 6 is larger than the thickness of the right seat cushion 11. The upper surface of the child seat forms a part of the side seating surface 7d when the child seat is stored, and becomes a seating surface as a child seat when used.

  Moreover, in the said embodiment, the protrusion amount with respect to the side back surface 7d of the center back surface 7c is made into the protrusion amount with respect to the side seating surface 6d of the side support part 6e of the left seat cushion 6, and the side support part 7e of the left seat back 7. However, the present invention is not limited to this. For example, the vehicle seat device 1 has three seats arranged in the vehicle width direction, and a side support portion is not formed on the central seat located in the center of these three seats, and is located on both sides of the central seat. When the side support part is formed at the outer end of the side seat in the vehicle width direction, the amount of protrusion of the retracted armrest provided on the seat back of the center seat with respect to the backrest surface of the side seat The side support part of the side seat back of the side seat is made smaller than the amount of protrusion of the seat back against the backrest surface, and the interlock mechanism is provided only on the seat cushion support part of both side seats, eliminating the difference in the amount of protrusion. If possible, move the seat cushions of both side seats to the lower side by the above interlocking mechanism, The back of the seat back of the rectangular sheet may substantially be made to be positioned at the same height.

  Furthermore, in the said embodiment, although the vehicle seat apparatus 1 shall have the two sheets 2 and 3 arranged in a vehicle width direction, it may have three or more (especially three) sheets. . These seats have a thickness of at least one of the seat cushion and the seat back that is different between the seats, and when the seat back is in a lying state without moving the seat cushion downward, the height of the back of the seat back is increased. The positions are different from each other. Therefore, one of the seat cushion support portions that respectively support the seat cushion of the seat (the position where the height of the back surface of the seat back is the lowest when the seat back is in a lying state without moving the seat cushion downward) A seat cushion support portion (excluding a seat cushion support portion that supports the seat cushion of the seat) or all seat cushion support portions provided with an interlocking mechanism, and at least continuous in the vehicle width direction among the three or more seats Of the two seats, the seat cushion support portion has the interlocking mechanism, and the seat cushion has the interlocking mechanism. The amount of downward movement of the seat cushion by the interlocking mechanism is substantially equal to the back surface of the seatback when the at least two seats are lying down. What is necessary is just to set so that it may be located in the same height position. In particular, the amount of downward movement of the seat cushion by the interlocking mechanism in all seats in which the seat cushion support portion has the interlocking mechanism is set so that the backs of the seatbacks in the state where all the seats are lying are positioned at substantially the same height position. It is preferable to set so as to.
