[Problems to be solved by the invention]
The configuration disclosed in Patent Literature 1 is such that, of the front and rear seats, a rear seat can be switched between an upright state and a front-down state, and the rear seat can be switched into a front-down state. In addition, a concave portion for storing the rear seat needs to be formed on the floor surface behind the front seat. Further, even in the configuration disclosed in the above-mentioned prior art document 2, a recess for storing a seat is provided in a floor portion below the seat which can be switched to the front fold state.
[0006]
In recent years, it has been demanded that a so-called platform of a vehicle body including a vehicle cabin floor be shared as much as possible between vehicle types. However, in the configurations of Patent Literature 1 and Patent Literature 2, it is provided in other vehicle types for storing rear seats. Since a dedicated recess which is not required is required on the floor of the passenger compartment, sharing of the platform is hindered, which is disadvantageous in reducing the cost of the vehicle body.
[0007]
Particularly, in the configuration of Patent Document 2, when the seat back is switched from the upright state to the forward leaning state, the seat cushion itself moves rearward, so that the luggage is stored behind the seat back in the upright state. In this case, the seat interferes with the luggage when switching the seat back to the forward leaning state, so if the luggage is not removed once, the switching operation to the seat back forward leaning state cannot be performed, There was also the disadvantage of lack of convenience.

As shown in detail in FIGS. 3 and 4, the rear seat 20 is in a standing state in which the seat back 22 stands above the rear end of the seat cushion 21 (see FIG. 3), and the seat back 22 is placed on the seat cushion 21. It is configured to be switchable to a fore-leaved state (see FIG. 4). The back of the seat back 22 is covered with a so-called decorative plate 23.
On the rear floor F2 behind the rear seat 20, a box-shaped sub-trunk 40 described later is provided. This box-shaped sub-trunk 40 can also store luggage of a certain size.
[0020]
FIG. 5 is a perspective view showing a frame structure of the rear seat 20 and a mounting structure on the rear floor F2. The rear seat 20 has substantially the same structure as a conventionally known one, and a seat cushion 21 and a seat back 22 are respectively attached to a frame body (cushion frame 24 and back frame 27) by a foam material having appropriate elasticity. And the like, so as to cover the cushion bodies 25 and 28, respectively. Note that a spring 26 is stretched inside the cushion frame 24.
[0021]
In addition, a frame body 29 of a headrest is mounted on the upper side of the back frame 27. A cross member 50 for attaching a buckle 65 of the seat belt device of the rear seat 20 is disposed below and below the rear seat 20 as described later.
[0022]
As shown in FIGS. 3 to 5, a pair of left and right seat brackets 31 is fixed on the rear floor F2 for mounting the rear seat 20, and is provided at a substantially middle portion and a rear end portion of the seat bracket 31 in the front-rear direction. , An intermediate vertical wall 32 and a rear vertical wall 33 are erected.

The rear vertical wall 33 of the seat bracket 31 rotatably supports a shaft member 27s (pivot shaft) protruding in the vehicle width direction at a lower end portion of the back frame 27, and at the lower end portion of the back frame 27 in the vehicle width direction. An arc-shaped guide groove 33g through which a pin 27p protruding from the front end is inserted is provided. The seat back 22 can be switched between the upright state and the forward leaning state by rotating back and forth around the pivot shaft 27s in a state where the pins 27p are guided by the guide grooves 33g. It has become.
[0024]
A lower end side of a link member (guide link) that supports a front portion of the cushion frame 24 is rotatably supported on the intermediate vertical wall 32 of the seat bracket 31. The rear end of the cushion frame 24 is rotatably supported by a lower portion of the back frame 27.
[0025]
The upper end side of the guide link 34 is rotatably engaged with a pin-shaped striker 24p projecting in the vehicle width direction at a front portion of the cushion frame 24. A latch 35 remotely operated by a wire cable 36 is engaged with the striker 24p in a detachable manner. The latch 35 is rotatably attached to the cushion frame 24, and is operated to rotate via a wire cable 36 by operating a switch 37 attached to, for example, a rear end portion of the luggage compartment Sn.
[0026]
In a state where the latch 35 is engaged with the striker 24p, as shown in FIGS. 1 and 3, the seat cushion 21 is in a normal state in which the seat cushion 21 is relatively positioned so that an occupant can sit thereon. By operating the wire cable 36 to rotate the latch 35 and disengage the engagement with the striker 24p, the guide link 34 can rotate forward and downward, and interlocks with the rotation of the guide link 34. Then, the seat cushion 21 is moved forward and downward while being guided by the guide link 34.
[0027]
Then, with the movement of the seat cushion 21, the seat back 22 is rotated forward through the cushion frame 24, and the seat back 22 is set to the front-down state. Contrary to the above, when the seat cushion 21 is moved rearward and upward to bring the seat back 22 into the upright state, each of the members performs an operation opposite to the above.
[0028]
A rear wall of the vehicle is not provided with a partition wall that completely separates the cabin Sc and the luggage compartment Sn, and the luggage compartment Sn is formed so as to be substantially continuous with the luggage compartment Sc. When the seat back 22 of the rear seat 20 is in the upright state, the vehicle compartment Sc and the cargo room Sn are separated by the seat back 22 of the rear seat 20 (see FIG. 1). When the seat back 22 of the rear seat 20 is set to the forward leaning state in order to expand the luggage compartment Sn, the compartment Sc and the luggage compartment Sn are separated by the seat back 12 of the intermediate seat 10. (See FIG. 2).
[0029]
The seat cushion 21 of the rear seat 20 is a thin type in which the thickness is set as thin as possible in order to secure the space of the luggage compartment Sn as large as possible when the seat back 22 is in the forward leaning state. The cushion frame 24 of the seat cushion 21 is formed so that the front end side is curved downward so that the occupant can maintain good sitting comfort in the thin type.
By making the cushion frame 24 have such a shape, the thickness of the cushion material at the upper front side of the seat cushion 21 can be ensured to be thicker, and the sitting comfort of the seat 20 can be more favorably maintained.
[0030]
When the seat cushion 21 moves forward and downward with the forward and backward movement of the seat back 22, the front end side of the cushion frame 24 that is formed to be curved downward is positioned on the stepped surface of the vehicle floor F. The dimensions of each part of each component such as the cushion frame 24 and the guide link 34 are set so as to be located forward of the part Fs. Although not specifically shown, for example, a support member or the like for supporting the rear wheel suspension mechanism on the vehicle body side is attached to the back side of the step portion Fs.
[0031]
As described above, the rear seat 20 is installed on the rear floor F2 of the relatively high floor which is continuous with the front floor F1 of the relatively low floor via the step Fs, and makes the seat back 22 lean forward on the seat cushion 21. In this case, by moving the seat cushion 21 forward and downward by the guide link 34 in accordance with the forward leaning operation of the seat back 22, the seat height at the time of storage can be suppressed low, and the storage capacity of luggage is further improved. Can be improved. At this time, the front end portion curved downward of the cushion frame 24 is located forward of the step portion Fs of the vehicle interior floor surface F, so that the front end portion of the cushion frame 24 does not interfere with the rear floor F2.
[0032]
Further, when the seat back 22 is made to lean forward, the front end side of the cushion frame 24 of the seat cushion 21 moves so as to be located forward of the step portion Fs of the vehicle floor F with the forward leaning operation. Even when the luggage is stored behind the seat back 22 in the seat back upright state, it is possible to reliably avoid the interference between the seat 20 and the luggage when switching the seat back 22 to the forward leaning state. That is, it is possible to switch the seat back 22 to the forward leaning state without particularly impairing the convenience.
[0033]
A storage recess 30 that is recessed downward is formed in the rear floor F2 of the floor F at the rear of the vehicle. The storage recess 30 has a front upper portion covered by the rear seat 20 and a rear upper portion covered by the sub trunk 40. The storage recess 30 can more preferably store the spare tire 9 of the vehicle, and as shown in FIG. 7 described later, is formed in a circular shape having a predetermined diameter in plan view and has a predetermined depth. are doing.
[0034]
Incidentally, in a normal vehicle, a recessed portion which is depressed downward is generally formed on the floor of the luggage compartment for storing spare tires and the like, and only the recess is used. The provision of 30 does not hinder sharing of the platform of the vehicle body.
[0035]
As described above, since the rear seat 20 is substantially flush with the rear surface of the seat back 22 and the upper surface of the sub-trunk 40 in the seat back forward leaning state, a dedicated recess is not formed on the floor surface. In other words, the seat 20 can be stored in the seat back forward leaning state without hindering the sharing of the platform of the vehicle body. In addition, a relatively large luggage can be stored on the rear surface of the seat back 22 and the upper surface of the sub trunk 40, which are substantially flat and flat.
Note that, in the seat back fold state, the decorative plate 23 on the back surface of the seat back 22 is directed upward, so that the appearance is not particularly impaired even when the seat back 22 is in the fold state.
[0036]
Furthermore, the luggage can be stored in the storage recess 30 of the rear floor F2 located below the rear seat 20 and the sub trunk 40, and more sufficient luggage storage can be ensured as compared with the related art. . In addition, since the upper portion of the storage recess 30 is normally covered with the rear seat 20 and the upper portion of the rear portion is covered with the sub trunk 40, the appearance is not particularly impaired. Furthermore, since the spare tire 9 of the vehicle can be stored in the storage recess 30, when the sub-trunk 40 is disposed on the rear floor F <b> 2 behind the rear seat 20, the sub-trunk 40 and the rear seat 20 are located below the sub-trunk 40. The spare tire 9 can be stored without any trouble.
[0037]
As shown in FIGS. 6 and 7, the sub-trunk 40 includes a central portion 41 located at the center in the vehicle width direction, and a pair of side portions 42 located on both left and right sides of the central portion 41. The side portion 42 is fixed to the rear floor F2 behind the tire house 8 of the vehicle body. On the other hand, the central portion 41 is detachable from the rear floor F2.
[0038]
The left and right side portions 42 are formed in a box shape elongated in the front-rear direction, and the central portion 41 is formed in a horizontally long, relatively flat rectangular box shape. The sub-trunk central portion 41 is attached to the rear floor F2, so that the upper part of the storage recess 30 is covered. In addition, instead of making the subtrunk 40 a divided structure and making a part (central part 41) detachable from the floor F2, the subtrunk is made into an integral structure and the whole is detachable from the floor F2. It can also be.
[0039]
As described above, the sub-trunk 40 is configured such that at least the portion (central portion 41) covering the rear upper portion of the storage recess 30 is detachable from the floor F2 of the luggage compartment Sn. The baggage (specifically, the spare tire 9) can be taken in and out of the bag 30, and can be removed when not needed, which is more convenient.
[0040]
Particularly, in this case, the subtrunk 40 has a structure divided into a central portion 41 in the vehicle width direction and left and right side portions 42, and these side portions 42 are fixed to the rear floor F2, and only the central portion 41 is fixed. By being detachable from the rear floor F2, the detachable portion of the sub-trunk 40 can be made smaller, and the handling when performing the detaching operation can be made easier.
[0041]
As shown in FIGS. 8 and 9, the central portion 41 and the side portion 42 of the subtrunk 40 are each formed in a box shape that can be opened and closed, and cover the box-shaped main bodies 43 and 44 and the upper portion thereof so as to be opened and closed. It is composed of cover plates 45 and 46. The front portion of the side portion 42 is formed in a curved shape so as to fit to the rear portion of the tire house 8 of the vehicle body.
[0042]
An engaging protrusion 44k is provided on an inner side surface of the box-shaped body 44 of the side portion 42 in the vehicle width direction, and an engaging protrusion 44k is provided on an outer side surface of the box-shaped body 43 of the central portion 41 in the vehicle width direction. An engagement recess 43k corresponding to the portion 44k is formed. When the central portion 41 is moved in the vertical direction to be detached from the floor surface F2, the engaging concave portion 43k is disengaged / engaged from the engaging convex portion 44k of the side portion 42. I have.
[0043]
As described above, between the central portion 41 and the side portion 42 of the subtrunk 40, in order to detachably engage the central portion 41 with the side portion 42, the engaging concave portion 43k and the engaging convex portion 44k are used. Is provided, the attachment / detachment operation of the central portion 41 can be easily performed, and when the central portion 41 is used, the central portion 41 is attached to the side portion 42 (that is, the rear portion). It is possible to securely engage and fix (with respect to the floor F2).
[0044]
Next, a seat belt device for the rear seat 20 will be described.
As shown in FIGS. 6 and 7, the retractor 62 of the seat belt device for the rear seat 20 is mounted in the interior trim 7 that forms the rear side surface of the luggage compartment Sn. The seat belt 61 is pulled out from the retractor 62 and extends upward, then is pulled out from the opening 7h provided in the trim 7 toward the interior of the room, extends downward via the shoulder anchor 63, and has a terminal portion at the rear floor F2. Fixed on top. A tongue 64 is attached to a middle part of the seat belt 61 on the indoor side.
[0045]
In the present embodiment, as can be clearly understood from FIGS. 6 and 7, even when the storage recess 30 recessed downward is formed on the luggage compartment floor F <b> 2 immediately behind the rear seat 20, the load applied to the seat belt 61 is reduced. In order to allow the cross member 50 to be transmitted to the vehicle body side without passing through the rear seat 20, a cross member 50 having both ends fixed to the vehicle body side is provided above the storage recess 30 so as to be bridged in the vehicle width direction. Is provided. That is, a pair of brackets 51 are mounted on the floor surface F2 on both left and right sides of the luggage compartment Sn, and both ends of the cross member 50 are fixed to the pair of brackets 51.
[0046]
The other end of a buckle connecting member 66 having one end connected to a seat belt buckle 65 for detachably engaging the tongue 64 of the seat belt 61 is fixed to the cross member 50. The buckle 65 and the buckle connecting member 66 are provided for a left seat and a right seat. The buckle connecting member 66 is preferably made of webbing of the seat belt 61.
[0047]
As described above, since the end portion of the buckle connecting member 66 is fixed to the cross member 50, the load applied to the seat belt 61 in a state where the tongue 64 is locked to the buckle 65 at the time of a vehicle collision or the like, It is transmitted to the vehicle body via the cross member 50. That is, even when the recessed portion 30 which is recessed downward is formed in the vehicle body floor F <b> 2 immediately behind the rear seat 20, the load applied to the seat belt 61 can be transmitted to the vehicle body without passing through the rear seat 20. Can be.
[0048]
As a result, the rigidity required for the rear seat 20 can be set low, and the seat cushion 21 (that is, the entire seat) can be made thinner. In particular, the rigidity required for the seat 20 can be set low for the rear seat 20 of the type configured to be switchable between the seat back upright state and the seat back forward leaning state, and the seat cushion 21 is further thinned. And it is possible to secure a wider luggage space. In addition, the provision of the cross member 50 also has the effect of increasing the rigidity of the rear floor F2.
[0049]
The cross member 50 is positioned so as to avoid interference with the spare tire 9 when the spare tire 9 is taken in and out of the storage recess 30 for storing the spare tire (see FIGS. 1 and 2). (See FIG. 2).
Accordingly, even in a vehicle in which the storage recess 30 is provided in the rear floor F2 immediately behind the rear seat 20 to store the spare tire 9, the storage capacity of the spare tire 9 is ensured, and the seat belt 61 is secured in the event of a vehicle collision or the like. Can be transmitted directly to the vehicle body.
[0050]
The cross member 50 is positioned so that the upper portion thereof is covered with the seat back 22 in the seat back forward leaning state (see FIGS. 2 and 4).
Therefore, by providing the cross member 50, the appearance of the luggage compartment Sn when the seat back 22 is leaning forward is not particularly impaired.
[0051]
Further, as described above, the rear seat 20 is configured to be switchable between a seat back upright state and a seat back forward leaning state, and the seat cushion 21 is moved in the vehicle front-rear direction and the vertical direction in accordance with the switching operation of the seat back 22. Is mounted on the rear floor F2 so as to be movable (in this embodiment, in both directions). The buckle connecting member 66 is configured to follow such movement of the seat cushion 21. It is configured.
[0052]
As shown in FIG. 10, in the buckle connecting member 66, an intermediate portion from the fixing portion 67 (first fixing portion) to the buckle 65 with respect to the cross member 50 is attached to the seat cushion 21 by the second fixing portion 68 (specifically, Is fixed to the rear of the cushion frame 24). The buckle connecting member 66 can be fixed to the cross member 50 or the cushion frame 24 by various known methods such as screwing and riveting.
[0053]
The length between the first fixing portion 67 and the second fixing portion 68 is set to a length that allows the buckle connecting member 66 to follow the movement of the seat cushion 21. Specifically, when the seat cushion 21 moves, the guide link 34 of the rear seat 20 moves between the first fixing portion 67 and the second fixing portion 68 of the buckle connecting member 66, as shown in FIG. Is set so as to guide the seat cushion 21 such that the distance is substantially constant.
[0054]
As described above, since the buckle connecting member 66 is fixed to the seat cushion 21 by the second fixing portion 68 at an intermediate portion from the first fixing portion 67 to the buckle 65 with respect to the cross member 50, particularly, At times, the buckle 65 can be prevented from falling off from between the seat back 22 and the seat cushion 21, and the usability is improved. Further, since the length between the first and second fixing portions 67 and 68 of the buckle connecting member 66 is set to a length that allows the buckle connecting member 66 to follow the movement of the seat cushion 21, the seat cushion 21 The buckle connecting member 66 does not hinder the movement of the seat cushion 21 even if the seat cushion 22 can be moved in at least one of the vehicle front-rear direction and the vertical direction in accordance with the switching operation of the seat back 22.
[0055]
In particular, in this case, preferably, the seat cushion 21 is maintained such that the distance between the first and second fixing portions 67 and 68 of the buckle connecting member 66 is maintained substantially constant when the seat cushion 21 moves. Is provided on the rear seat 20, there is no need to provide slack in the buckle connecting member 66, and the occupant restraining force of the seat belt 61 at the time of a vehicle collision or the like can be further increased.
[0056]
Instead, as shown in FIG. 12, slack is given to the buckle connecting member 66 (see the broken line in FIG. 12) so that the buckle connecting member 66 can follow the movement of the seat cushion 21. May be. In this case, the dimensional accuracy of each member related to the guide operation of the seat cushion 21 by the guide link 34 can be set to a low level to some extent, so that the production is easy and the cost is low.
[0057]

【The invention's effect】
According to the present invention, it is possible to store a certain size of luggage in a box-shaped sub-trunk disposed on the rear floor of the luggage compartment behind the last row seat, Since the back of the seat back and the upper surface of the sub trunk are almost flush, the seat in the seat back forward fold state is stored without forming a dedicated recess on the floor, that is, without hindering the common platform of the vehicle body it can. In addition, a relatively large luggage can be stored above the flat back surface of the seat back and the upper surface of the subtrunk.
Further, the luggage can be stored in the storage recess on the floor of the luggage compartment located below the rearmost row seat and the sub trunk, and more sufficient luggage storage can be ensured as compared with the related art. . In addition, the appearance of the storage recess is not particularly impaired because the upper front portion is normally covered with the last row seat and the upper rear portion is covered with the sub trunk.
In this case, since the sub-trunk is configured so that at least a portion covering the rear upper part of the storage recess is detachable from the floor surface of the luggage compartment, it is possible to carry out luggage into and out of the storage recess without trouble. Yes, and can be removed when not needed, improving convenience. In addition, in a normal vehicle, a concave portion which is depressed downward is generally formed on a floor surface of a luggage compartment for storing spare tires and the like. Commonality is not hindered.
[0060]
In the above invention, preferably, when the spare tire of the vehicle can be stored in the storage recess, when the subtrunk is disposed on the rear floor of the luggage compartment behind the last row seat, the subtrunk and the last row are arranged. The spare tire can be stored in the storage recess located below the seat.
[0061]
Further, in the above invention, the sub-trunk is constituted by a central portion in the vehicle width direction and left and right side portions, and these side portions are fixed to the luggage compartment floor surface, and only the central portion is the luggage compartment floor surface. By making the sub-trunk detachable, the sub-trunk detachable portion can be made smaller, and handling when performing the detaching operation becomes easy.
[0062]
In this case, preferably, an engagement mechanism for detachably engaging the central portion with the side portion is provided between the central portion and the side portion of the sub trunk, so that the central portion can be attached and detached. The operation can be performed easily, and when the central portion is used, the central portion can be securely engaged and fixed to the side portion (that is, to the cargo room floor surface).
[0063]
Further, in the above case, the rear row seat is installed on the rear floor of the relatively high floor which is continuous with the front floor of the relatively low floor via the step portion. As a result, the seat cushion can be moved downward with the forward and backward movement of the seat back, so that the seat height at the time of storage can be kept low and the luggage storage capacity can be further improved. Moreover, the cushion frame of the seat cushion of the last row seat is formed so that the front end side is curved downward, so that the thickness of the cushion material at the upper front side of the seat cushion can be ensured to be greater, and The sitting comfort can be improved. In addition, when the seat back is lowered, the front end side of the seat cushion frame moves forward with respect to the stepped portion of the floor of the passenger compartment along with the fore-lowering operation. Even when luggage is stored behind the seat back, it is possible to reliably avoid interference between the seat and the luggage when switching the seat back to the forward leaning state, and to lower the seat back without lowering convenience. State. Further, at this time, the front end portion curved downward of the cushion frame is located forward of the step on the floor surface of the passenger compartment, so that the front end portion of the cushion frame does not interfere with the rear floor. The configuration in which the front part of the floor F at the rear of the vehicle is relatively low on the front side and the rear part is relatively high on the floor, and the two parts are connected by steps is a configuration generally employed in ordinary vehicles. Yes, it does not prevent platform commonality.
