A U-shaped gate portion 94a is formed at the rear end of the guide portion 94, and a slit-shaped insertion passage 95 (see FIG. 6) is formed by the gate portion 94a and the rear edge portion of the insertion hole 93a.

  Here, as shown in FIGS. 1, 2, 5, and 6, the retractor 62 has a shaft portion 62 a that fixes one end side of the seat belt 63. The shaft portion 62 a Is urged to rotate in the direction of winding. Further, as shown in FIG. 5, the retractor 62 has a belt guide 62b, and the belt guide 62b guides the seat belt 63 so as to be pulled out from the retractor 62 in a predetermined direction. In FIG. 6, the belt guide 62b is not shown for convenience of illustration.

  The seat belt 63 is pulled out rearward from the retractor 62 while being guided by the belt guide 62b, and is inserted into an insertion hole 93a formed in the cover main body 93 of the cover member 92. Then, the seat belt 63 is drawn out into the passenger compartment space through the insertion passage 95 by the guide of the guide portion 94. A slit for inserting the seat belt 63 is formed in the floor mat 91 corresponding to the position of the insertion path 95.

  Thus, in this embodiment, a substantially flat bottom surface of the passenger compartment is formed above the floor panel 1 by the upper surface of the floor filling member 9, and the retractor 62 of the seat belt device 60 is connected to the hole 9 a of the floor filling member 9. The retractor 62 can be prevented from protruding upward from the bottom surface of the passenger compartment.

  Therefore, the retractor 62 restricts the foot space of the occupant C1 or the like, or the movement of the occupant in the passenger compartment is obstructed by the second row seat 2 (here, the seat cushion 30a of the right seat 2a in particular). It can be prevented regardless of the front-rear position, and damage to the retractor 62 due to contact with the occupant can be prevented. Accordingly, it is possible to improve the degree of freedom of setting the range of forward and backward movement of the second row seats 2, and as a result, diversification of the seat arrangement can be realized.

  Further, since the hole 9a of the floor filling member 9 is closed by the cover member 92, the retractor 62 can be concealed and can be reliably protected. When the seat belt 63 is pulled out and rewound, it can be appropriately guided by the guide portion 94 and the insertion path 95.

  Further, as shown in FIGS. 1, 4, and 7, the seat belt device 60 extends the seat belt 63 pulled rearward from the retractor 62 along the rear surface of the seat back 40a at the rear ends of the upper rails 12 and 12. It has a lower guide 64 that guides it to deflect upward.

  As shown in FIG. 7, the lower guide 64 is provided on the shaft member 14 that extends in the vehicle width direction and connects the rear end portion of the upper rail 12.

  Further, the lower guide 64 has a hollow cylindrical shape as shown in FIGS. 7 and 8, and a guide main body 64a that is rotatably fitted at the center portion in the vehicle width direction of the shaft member 14, and a flange portion 64b. , Pin 64c and coil spring 64d.

  Here, two flange portions 64b and 64b are fixed to the shaft member 14 by pins 64c, and the guide main body 64a is disposed between the flange portions 64b and 64b. Further, one end side of the coil springs 64d and 64d is fixed to the inner surface side of the flange portions 64b and 64b, respectively, and the other end side is slidable on the large diameter portion 64f formed outside the flange portion 64e of the guide body 64a. It is wound around.

  With such a configuration, the guide body 64a has the flange portions 64b and 64b due to the elastic deformation of the coil springs 64d and 64d, while the large displacement in the vehicle width direction is restricted by the flange portion 64b and the coil springs 64d and 64d. In the meantime, the tension applied to the seat belt 63 and the reaction force of the coil spring 64d are balanced, so that the seat belt 63 can be displaced to a position where the seat belt 63 can be stretched through an optimum path. Although the position of the seat belt 63 in the vehicle width direction with respect to the guide main body 64a is regulated by the flange portion 64e of the guide main body 64a, a slight displacement between the flange portions 64b and 64b is allowed by the displacement of the guide main body 64a. Is done.

  Further, when the seat belt 63 is displaced in the front-rear direction, the guide main body 64a does not rotate, so that the seat belt 63 is pulled out and rewound while sliding with respect to the guide main body 64a, and friction is generated. Therefore, a frictional resistance may be reduced by mounting a circular collar member on the guide body 64a in a rotatable manner and rotating the collar member together with the withdrawal and rewinding of the seat belt 63 in contact therewith. .

  Further, the seat belt device 60 has the seat belt 63 guided by the lower guide 64 on the rear surface of the seat back 40a at the upper end in the vehicle width direction of the seat back 40a. It has an upper guide 65 that guides it to the vicinity of the inner shoulder.

  As shown in FIG. 7, one end of the upper guide 65 is sewn to the upper end of the seat back 40a, and the other end is fixed to the upper end of the seat back 40a by a hook 65a. The seat belt 63 is inserted between both end portions of the upper guide portion 65 fixed by the method described above, and the position in the vehicle width direction is thereby restricted.

  The seat belt 63 is pulled out from the retractor 62 so as to extend rearward and along the rear surface of the seat back 40a by the above-described guides 64, and the upper guide 65 contacts the upper end portion and the front surface of the seat back 40a. It is deflected forward while touching. The seat belt 63 can be pulled out from the upper guide 65 to the central seat S1 (see FIG. 4).

  Further, as shown in FIGS. 2 and 4, a first tongue 66a is attached to the other end side of the seat belt 63. Further, between the first tongue 66a and the upper guide 65, FIG. As shown in FIGS. 2 and 4, a second tongue 66b is provided. The second tongue 66b is inserted with the seat belt 63 and is slidable along the longitudinal direction of the seat belt 63.

  As shown in FIG. 2, the first tongue 66a can be engaged with a buckle 67a disposed on the seat cushion 30a of the right seat 2a, and the second tongue 66b is shown in FIGS. As described above, it is possible to engage with the buckle 67b of the left seat 2b.

  Here, the seat cushions 30a and 30b of the right seat 2a and the left seat 2b are respectively provided with buckles 67a and 67b near the central seat S1. As shown in FIG. 2, the buckle 67a (67b) has a base portion 67c wound around the cross bar 32 of the seat cushion 30a (30b) and fastened with bolts, nuts, or the like. It is fixed to.

  When the seat belt 63 is used, by engaging the first tongue 66a with the buckle 67a and the second tongue 66b with the buckle 67b, respectively, as shown in FIG. While restraining the shoulder and chest of the occupant C1 at the portion (shoulder belt portion) 63a between the tongue 66b, the occupant C1 at the portion (lap belt portion) 63b between the first and second tongues 66a and 66b. The lower back can be restrained. Thereby, the passenger | crew C1 seated in the center seat S1 can be restrained by what is called a three-point system.

  Further, as shown in FIG. 1, the seat belt device 70 includes a retractor 71 accommodated in the trim 7 by the C pillar 8. Similar to the retractor 62, the retractor 71 has a shaft portion 71 a that fixes one end of the seat belt 72, and is urged to rotate in a direction in which the seat belt 72 is wound up.

  The seat belt 72 pulled out from the retractor 71 is guided upward by a shoulder anchor 73 fixed to the C pillar 8 and is deflected toward the vehicle interior side, so that it can be pulled out to the side seats S2 and S3. .

  The other end side of the seat belt 72 is fixed to a second anchor (not shown) on the vehicle body side, and a tongue 74 is provided between the shoulder anchor 73 and the second anchor. The tongue 74 has a seat belt 72 inserted therethrough and is slidable along the longitudinal direction of the seat belt 72.

  As shown in FIG. 2, the tongue 74 of the seat belt device 70 on the right side of the vehicle can be engaged with the buckle 75a disposed on the seat cushion 30a of the right seat 2a, and the tongue 74 of the seat belt device 70 on the left side of the vehicle. Is engageable with the buckle 75b of the left seat 2b.

  Here, the seat cushions 30a and 30b of the right seat 2a and the left seat 2b are respectively provided with buckles 75a and 75b near the central seat S1. As shown in FIG. 2, the buckle 75a (75b) has a base portion 75c wound around the cross bar 32 of the seat cushion 30a (30b) and fastened with bolts, nuts, etc. It is fixed to.

  When the seat belt 72 is used, by engaging the tongues 74 and 74 with the buckles 75a and 75b, as shown in FIG. 4, a portion (shoulder) between the shoulder anchor 73 and the tongue 74 of the seat belt 72 is used. The belt portion 72a restrains the shoulders and chests of the occupants C2 and C3, while the portion (lap belt portion) 72b between the tongue 74 and the second anchor restrains the occupant C2 and C3 waist. it can. Thereby, the passengers C2 and C3 seated in the side seats S2 and S3 can be restrained by a so-called three-point system.

  As described above, in this embodiment, the seat belt 63 pulled out from the retractor 62 of the floor panel 1 restrains the occupant C2 seated on the central seat S1 of the second row seat 2 in a three-point manner, and The seat belt 72 drawn from the retractor 71 of the C pillar 8 via the shoulder anchor 73 can restrain the passengers C2 and C3 of the side seats S2 and S3 in a three-point manner.

  In this case, the seat belts 63 and 72 are prevented from crossing the upper space of the passenger compartment, and the center seat S1 seated on the second row seat 2 without impeding the comfort of other passengers such as the third row seat 3 is prevented. The occupant C1 and the occupants C2 and C3 of the side seats S2 and S3 can be restrained by a three-point system.

  Further, in the event of a front collision or the like, most of the extension load acting on the seat belt 63 due to the restraint of the upper body of the occupant C1 can be transmitted to the floor panel 1 via the retractor 62, while the occupant C2 , Most of the extension load acting on the seat belt 72 due to the restraint of the upper body of C3 can be transmitted to the left and right C pillars 8 and 8 and the trims 7 and 7 via the shoulder anchor 73 and the retractor 71. Each spreading load can be efficiently distributed to various parts of the vehicle body.

  Here, a part of the extension load of the seat belt 63 acts as a force for the shoulder belt portion 63a to push the shaft member 14 of the upper rail 12 upward through the lower guide 64 and a force for moving the seat back 40a forward. The lap belt portion 63b acts as a force for pulling up the cross bar 32 diagonally forward and upward via the buckles 67a and 67b. However, since these are relatively small loads, the reinforcement accompanying the increase in weight of the second row seat 2 and the front / rear slide mechanism 10 can be minimized.

  Further, part of the extension load of the seat belt 72 is such that the lap belt portion 72b pulls the cross bar 32 obliquely forward and upward via the buckles 75a and 75b, and the vehicle body side via the second anchor. The side sill (not shown) located at the lower part of the part acts substantially equally as a force for pulling up diagonally forward. However, since these are relatively small loads, the reinforcement associated with the weight increase of the second row seat 2, the front / rear slide mechanism 10, and the side sill can be minimized.

  By the way, in the present embodiment, the upper rail 22 of the lateral sliding mechanism 20 slides laterally with respect to the lower rail 21, whereby the right-side seat 2a and the left-side seat 2b are separated from each other in the second row seat 2 as shown in FIG. It is also possible to arrange the seats so that the passengers C4 and C5 can be seated one by one on each seat 2a and 2b.

  At this time, by separating the right sheet 2a and the left sheet 2b from each other, an intermediate passage R is formed between the sheets 2a and 2b. Thus, for example, a so-called walk-through in which a third row of occupants (not shown) moves to the first row of seats through the intermediate passage R is possible.

  Further, in the state shown in FIG. 9, passengers C4 and C5 seated on the side seats S4 and S5 of the seats 2a and 2b by the seat belts 72 and 72 of the seat belt devices 70 and 70 provided on the vehicle side portions, respectively. The seat belt device 60 for the central seat S1 (see FIG. 4) is not necessary. Therefore, in practice, a storage portion is formed on a part of the surface of the seat back 40a, and the first and second tongues 66a and 66b are locked to the storage portion, thereby obstructing the occupant C4. The seat belt 63 is stored in such a state that it does not become.

  Here, with respect to the seat belt device 60, the retractor 62 is disposed between the lower rails 11 and 11 corresponding to the right seat 30 a as described above, whereby interference between the seat belt 63 and the front and rear slide mechanism 10. The seat belt 63 is prevented from extending onto the intermediate passage R. This prevents the passenger from passing through the intermediate passage R by the seat belt 63.

  However, by arranging the retractor 62 between the lower rails 11 and 11 in this way, the retractor 62 is guided by the position of the seat belt 63 (upper guide 65) at the upper end of the seat back 40a in the vehicle width direction. The position is greatly deviated from the position) to the outside of the vehicle. For this reason, when the right seat 2a is moved back and forth, the direction in which the seat belt 63 is pulled out from the retractor 62 toward the upper guide 65 changes as shown by the broken line and the two-dot chain line in FIG. Normally, the position of the seat belt 63 in the vehicle width direction changes in the vicinity of the deflection portion by the lower guide 64.

  Here, if the position of the guide body 64a of the lower guide 64 is not changed, when the right seat 2a is moved back and forth, the seat belt 63 may be bent largely by the guide body 64a. As a result, the seat belt 63 may be twisted in the vicinity of the deflection portion.

  Such twisting of the seat belt 63 causes the seat belt 63 to be caught in the lower guide 64, and in some cases, the seat belt 63 is slackened. Such looseness of the seat belt 63 is not preferable because it restrains the occupant C1 sufficiently.

  Further, as described above, if the seat belt 63 is bent by the lower guide 64, when the occupant suddenly pulls the seat belt 63, the seat belt 63 may be detached from the lower guide 64 due to the tension of the seat belt 63. .

  Therefore, in the present embodiment, as shown in FIGS. 7 and 8, a coil spring 64d is provided, and is configured to allow minute displacement in the vehicle width direction of the guide body 64a by elastic deformation thereof. Thereby, the displacement of the seat belt 63 accompanying the back-and-forth movement of the right seat 2a can be allowed by the displacement of the guide body 64a as shown in FIG. For this reason, the seat belt 63 can be guided at an appropriate position regardless of the front-rear position of the right seat 2a, and the pull-out path of the seat belt 63 can always be optimized.

  Further, regarding the arrangement of the lower guide 64, the support strength can be improved and the durability against the load of the seat belt 63 can be improved by arranging the lower guide 64 on the shaft member 14 below the seat cushion 30a.

  By the way, in this embodiment, the seat belt 63 can be freely engaged with and disengaged from the right seat 2a by the first tongue 66a attached to the other end side of the seat belt 63. Therefore, when the right seat 2a is assembled to the vehicle body, the upper guide 65 and the upper end of the seat back 40a are held while the first and second tongues 66a and 66b are held on the front side of the seat back 40a rather than the upper guide 65. The seat belt 63 can be set by passing the seat belt 63 between the upper guide 65 and the other end of the upper guide 65 with a hook 65a (see FIG. 7).

  Further, when the engagement state between the first and second tongues 66a and 66b and the buckles 67a and 67b is released and the hook 65a of the lower guide 65 is removed from the seat back 40a, the right belt 2a is restrained by the seat belt 63. Can be released. For this reason, when the right seat 2a needs maintenance or the like, the right seat 2a can be removed from the vehicle body by releasing the engagement state.

  However, the present invention is not limited thereto, for example, like the seat belt 63 ′ shown in FIGS. 11 to 14, while the other end side is fixed to the right seat 2a, the seat belt 63 is connected in the middle in the longitudinal direction by engagement / disengagement. A coupling mechanism 80 for dividing may be provided. In FIG. 11 to FIG. 14, the same components as those in the first embodiment shown in FIG. 1 to FIG.

  The coupling mechanism 80 is disposed on the seat belt 63 'between the retractor 62 and the upper end of the seat back 40a as shown in the drawing in order to avoid contact with the passenger using the seat belt device 60'. ing.

  As shown in FIGS. 12 to 14, the coupling mechanism 80 includes a tongue 81 on the retractor 62 side and a buckle 82 on the right seat 2 a side. As shown in FIG. 13, a tongue plate 81 a is provided at the tip of the tongue 81, and this can be engaged with and disengaged from the buckle 82. Also, a release operation button 82a is provided on the buckle 82 side. When the release operation button 82a is pressed while the tongue plate 81a is engaged with the buckle 82, the tongue 81 (the tongue plate 81a) It can be detached from the buckle 82.

  With such a configuration, when the right seat 2a is assembled to the vehicle body, the seat belt 63 'can be easily set only by engaging the tongue 81 (the tongue plate 81a) with the buckle 82.

  Moreover, if the engagement state of the tongue 81 and the buckle 82 is released, the restraint state of the right seat 2a by the seat belt 63 'can be released. For this reason, when the right seat 2a needs maintenance or the like, the right seat 2a can be removed from the vehicle body by releasing the engagement state.

  As described above, in the seat belt 63 ′, the coupling mechanism 80 is provided between the retractor 62 and the upper end of the seat back 40a of the right seat 2a. Setting work and removal work of the right seat 2a can be easily performed, and workability at each work can be improved.

For example, the right sheet 102a and the left sheet 102b may be asymmetric as in the second row sheet 102 shown in FIG. In FIG. 15, the same components as those in the first embodiment shown in FIGS. 1 to 10 are denoted by the same reference numerals and description thereof is omitted.

  In the embodiment shown in FIG. 15, the length of the seat cushion 130a and the seat back 140a of the right seat 102a is set longer than that of the left seat 102b, and the central seat S101 is formed only by the right seat 102a. In other words, the seat cushion and the seat back of the central seat S101 and the right side seat S102 are integrally formed on the right seat 102a.

  For this reason, a central seat S101 and a right side seat S102 are formed on the right seat 102a, and the right seat 102a is a bench-type seat on which two passengers C6 and C7 can be seated in parallel. On the other hand, in the left seat 102b, only the left side seat S103 is formed, and one passenger can be seated. Therefore, the second row sheet 102 can also be seated by three persons by the sheets 102a and 102b.

  Here, in the case of FIG. 4 in which the seats 2a and 2b are formed substantially symmetrically, the buttocks of the occupant C1 are located at the boundary between the left and right seats 2a and 2b. In this case, the boundary between the seats 102a and 102b is located on the left side of the occupant C6. Therefore, the comfort of the occupant C6 can be improved by the configuration of the right seat 102a as shown in FIG.
