Description

[Detailed explanation of the idea] [Industrial application field]

This invention relates to a vehicle body structure specifically constructed to lock the legs of a folding seat to the floor when in use.

[Prior art and its problems]

Recently, automobiles equipped with folding seats, so-called space-up seats, as shown in FIG. 1, are being developed. Unlike simple folding auxiliary seats installed in buses, wagons, etc., this folding seat 1 has almost the same functionality and riding comfort as a separate floor seat, but when not needed, it can be placed on the wall of the passenger compartment. It is constructed so that it can be folded and stored. That is, this sheet 1 is
As shown in the figure, a seat cushion 4 is supported on the upper surface of the rear wheel tire house 2 via a hinge 3 so as to be laterally rotatable, and a reclining mechanism is provided for the seat cushion 4. The seat cushion 4 is provided with a seat back 6 which is supported so as to be able to fall backwards via a seat cushion 5, and a foldable leg 7 is attached to the lower surface of the seat cushion 4 on the inside of the vehicle. 1st
When folding and storing the seat from the usage state shown by the solid line in the figure, first, the seat back 6 is fully reclined to the rear, and then the seat cushion 4 is rotated upright toward the interior wall of the vehicle. Then, as shown by the two-dot chain line, the seat 1 is stored so that the seat cushion 4 and the seat bag 6 are continuous along the inner side wall of the vehicle. In this case, the stored seat 1 bulges out from the inside wall of the vehicle by only the thickness of the seat cushion 4 or the seat bag 6, so the interior width of the vehicle is not reduced significantly, and the length of the vehicle interior is not reduced at all. By the way, when the folding seat 1 as described above is installed, it is necessary to ensure that it is securely locked to the vehicle body when used as a seat. It is conceivable to provide a mechanism for locking the leg 7 of the seat 1 to the floor 8, but in particular in this case,
There should be no protrusions on the floor when the seats are in the stowed state. Furthermore, since it is necessary to ensure that there are no protrusions on the floor when the seat is in the stored state, it is not possible to provide a floor-fixed inner belt like the inner belt of a normal three-point seat belt. Conventionally, a locking mechanism for folding seats has been proposed in which a locking mechanism is attached to the rotating mechanism of the seat cushion, but a locking mechanism for folding seats with a full-fledged structure and function as shown in Fig. 1 has been proposed. It is unsuitable as a mechanism in terms of strength, etc. This invention was devised under the above-mentioned circumstances, and allows the legs 7 of the folding seat shown in Fig. 1 to be safely and securely fixed to the floor 8. To provide a vehicle body structure in a lock part of a folding seat configured so that there are almost no protrusions on the floor when stored.

[Means to achieve the task]

In order to achieve the above-mentioned object, the following technical measures are taken in the vehicle body structure of the lock portion of the folding seat of the present invention. In a vehicle body floor constructed by welding an upwardly opening channel-shaped cross member to the lower surface of the floor panel, the front and rear edges are welded onto the front and rear flanges of the cross member, and there is a concave part in the center. is formed, and includes a support part that runs along the back surface of the floor panel, and a standing wall part that is bent from the left and right edges of this support part so as to close the cross section of the cross member, and whose peripheral edge is welded to the inner surface of the cross member. A member is provided, a through hole is provided in the floor panel so that the recessed portion is exposed in the through hole, and the recessed portion is extended over the supporting portion of the reinforcing member or the upper surface of the floor panel overlapping with the supporting portion of the reinforcing member. A rod-shaped striker is fixed to the.

[Action and effect]

The folding sheet is fixed by engaging a latch member attached to the foldable leg with a rod-shaped striker fixed to span a recess formed in the upper support portion of the reinforcing member. When the sheet is fixed in use, the latch pawl engages the striker while the tip of the latch member enters the recess. Since the seat is thus fixed by engaging the latch member and the striker, the seat locking operation can be performed quickly, easily and reliably. In addition, since only a rod-shaped striker with a small protrusion is attached to the upper surface of the floor at the seat fixing part, there are virtually no protrusions on the floor when the seat is stowed, and the floor when the seat is put away can be effectively used as a luggage compartment, etc. The floor to which the striker is attached is reinforced extremely firmly by interposing the reinforcing member between the floor panel and the upwardly opening channel-shaped cross member. That is, not only is a substantially closed rectangular parallelepiped box structure formed by the upper surface support portion of the reinforcing member, the left and right vertical walls, and the inner surface of the channel-shaped cross member, but also a recessed portion is formed in the upper surface support portion. By forming this, the rigidity of the box structure becomes extremely high. Therefore, the load applied to the upper surface support portion of the reinforcing member is effectively supported by the cross member or the vehicle body surrounding it via the box structure, so the load bearing capacity of the striker is extremely high. .
For this reason, the above-mentioned striker can obtain sufficient load bearing capacity as a seatbelt anchor, and the base of the seatbelt is fixed to the latch member attached to the leg of the seat. The load can be reliably supported by the vehicle body via the striker.

[Explanation of Examples]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of a vehicle body structure of a locking portion of a folding seat according to the present invention will be described in detail with reference to the drawings. As shown in FIG. 3, a cross member 11 in the shape of an upwardly opening channel is provided at a suitable part of the rear floor panel 10, for example, on the back surface of the part that crosses between the left and right rear tire houses 2, with its front flange part 12 and rear flange part. 13 are provided by spot welding to the back surface of the floor panel 10, respectively. The right portion of the cross member 11 in the left-right direction, that is, the portion where the legs 7 of the folding sheet 1 shown in FIGS. 1 and 3 are located, is reinforced by a reinforcing member 14 as described below. That is, this reinforcing member 14 has a front edge 15a and a rear edge 15b that are connected to the front flange 1 of the cross member 11.
2 and the rear flange 13, a recessed part 16 is integrally press-molded in the center, and a support part 15 along the back surface of the floor panel 10 is provided.
A standing wall portion 17 is bent from the left and right edges of the support portion 15 so as to close the cross section of the cross member 11, and the peripheral edge is welded to the inner surface of the cross member 11.
Equipped with. The peripheral edge of the vertical wall portion 17 is fixed to the inner surface of the cross member 11 by fillet welding, as shown in FIG. As shown in FIGS. 3 and 4, the recessed portion 16 is formed on the folding sheet 1.
The tip of the latch member 18 attached to the leg 7 of the latch member 18 is formed so that it can be inserted into the latch member 18. As shown in FIG. 5, bolt holes 20 for fixing both ends of the rod-shaped striker 19 are drilled in the upper support portion 15 of the reinforcing member 14 at a portion that laterally sandwiches the recessed portion 16. A weld nut 21 is fixed to the back side. On the other hand, a through hole 22 for exposing the recess 16 is bored in a portion of the floor panel 10 that corresponds to the recess 16 of the upper support portion 15 of the reinforcing member 14, and corresponds to the bolt hole 20. A bolt through hole 23 is drilled. The rod-shaped striker 19 has a bolt hole 24 in a flat part 19a formed at both ends thereof, and the threaded part 25a of a bolt 25 passed through the bolt hole 24 from above is inserted into the bolt hole of the upper support part of the floor panel and reinforcing member. It is fixed by tightening the weld nuts 20 and 23 to the weld nut 21. As is clear from FIG. 5, in the present invention, a strong and robust support portion 15 for supporting the striker 19 is created by welding and fixing a reinforcing member 14 of a predetermined shape to the upwardly opening channel-shaped cross member 11. It is formed. That is, this reinforcing member 14
connects the front and rear edges 15a, 15b of the support portion 15 to the front and rear flanges 1 of the cross member 11, respectively.
2, 13, and this support part 15
Since the peripheral edge of the upright wall portion 17 that hangs down from both sides of the cross member and closes the cross section of the cross member is welded to the inner surface of the cross member 11, the longitudinal part of the cross member 11 separated by the reinforcing member 14 and A closed rectangular parallelepiped box component is constructed, and the load applied to the striker 19 is transferred to the support section 1.
It is possible to reliably support the cross member 11 or its peripheral vehicle body structure via the front and rear edges 15a, 15b of 5 and the peripheral edge of the vertical wall portion 17. In addition, since the recessed portion 16 is integrally formed in the upper surface support portion 15 of the reinforcing member 14, the rigidity of this upper surface support portion 15 is also very high. From the above, as shown in Figure 3,
The anchor plate 27 of the seat belt 26 is attached to the latch member 18 to be attached to the leg 7 of the seat 1.
By installing this striker 19,
It is also fully possible to function as a seatbelt anchor that can make the vehicle body reliably absorb the enormous load applied to the seatbelt 26 in an emergency. In addition, the latch member 18 has its tip inserted into the concave portion 16 of the reinforcing member 14 so as to engage the striker 19, so that only the rod-shaped striker 19 protrudes from the floor panel when the seat is stored. I will do it. however,
This amount of protrusion is approximately equivalent to the diameter of the rod, and by laying a carpet on the floor or slightly lowering the floor panel where it overlaps with the cross member as shown in Figure 3, it can be effectively In particular, it is possible to prevent any protrusions from remaining on the floor. Of course, the scope of the present invention is not limited to the embodiment shown in the drawings; for example, the shape of the cross member is not limited to an inverted hat shape in cross section as in the embodiment, but may also be shaped in cooperation with the floor panel. This includes all shapes that can be used to form a closed cross-sectional structure.
