In the case of the above-mentioned conventional seat holding device, when the resin hook 29 is detached from the assist grip 25 in order to store and pull out the seat 21, the seat holding band is attached. 28 length adjustment,
That is, the operation of tightening or loosening the band is required. However, since the conventional structure is such that the band pull-out portion 28c is fixed to the band body 28a by the magic fastener 33, the magic fastener 3 is used each time.
There is an operational inconvenience that it is necessary to attach and detach 3.

Further, as shown in FIG. 7B, when the vehicle is traveling, the seat holding band 28 is repeatedly moved in the pulling direction and the slacking direction by the vertical movement of the seat 21 due to the vibration of the vehicle body, and then in the slacking direction. At the time of fluctuation, the slack may occur in the form shown by the broken line. At that time, the folded-back portion 28b is separated from the corner portion 30c of the outlet-side opening 30b of the through hole 30. Therefore, at this time, if the magic fastener 33 is not fixed as shown by the broken line in the drawing, when a force acts in the pulling direction. Loosening occurs, which is gradually accumulated and the band stretches out.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a vehicle seat holding device in which the seat holding band is not easily loosened and the band length is easily adjusted. To provide.

[0007]

In order to solve the above problems, the present invention takes the following means. That is, claim 1
Is a vehicle seat holding device for folding a seat cushion and a seat back and storing them in a flip-up manner to the side body side, wherein a hook detachable from the side body and one end of the folding seat are provided. Fixed to
And a sheet holding band having the other end connected to the hook in a length-adjustable manner, and the hook is provided with the other end of the sheet holding band for pulling back from the one side of the hook to the same side. It is characterized in that a through hole and a guide hole for guiding the folded-back portion pulled out from the through hole further in the opposite direction and guiding so as to pull it out in a direction parallel to the tension direction of the band.

In this case, it is desirable that the band draw-out port of the guide hole is set to have a width equal to the band width of the sheet holding band.

[0009]

Therefore, according to the invention of claim 1 configured as described above, since the folded portion pulled out from the through hole of the hook is further folded in the opposite direction, the sheet holding band for holding the folded sheet. In the tightened state, the folded-back portion is caught by the corner portion on the outlet side of the through hole and the corner portion on the inlet side of the guide hole to generate a reaction force. Therefore, even if the seat holding band repeatedly changes in the pulling direction and the slacking direction due to the vehicle body vibration during traveling,
Since the hooked state with respect to both corners of the folded-back portion is maintained, the occurrence of loosening due to the sheet holding band being pulled out from the hook is suppressed. In this case, when the width of the outlet of the guide hole is formed to be equal to the band width, lateral displacement of the folded-back portion is prevented, so that the both corners are properly caught.

The length of the sheet holding band can be adjusted, that is, the band can be tightened by pulling the pull-out end portion from the guide hole, and the hook can be tilted with respect to the tension direction of the sheet holding band. The seat holding band can be easily loosened by pulling away the folded-back portion from the band body.

[0011]

Embodiments of the present invention will be specifically described below with reference to FIGS. The seat holding device according to the present embodiment is used, for example, in a van type vehicle when the folding seat is folded and stored to the side body side to be stored and held up, and as shown in FIGS. 1 and 2. It is composed of a sheet holding band 1 made of a synthetic fiber material having flexibility and a proper rigidity, and a resin hook 2. It should be noted that one end of the seat holding band 1 is fixed to the lower surface of the seat cushion of the foldable seat via a mounting bracket, and the hook 2 can be engaged with and disengaged from the assist grip of the side body of the vehicle body as in the conventional case. is there.

The hook 2 is made of a resin plate having a substantially rectangular shape and wider than the band width, and has a hook portion 2a which can be hooked and unhooked by an assist grip at one end in the longitudinal direction and the seat holding band 1 at the other end. The other end is connected so that its length can be adjusted. Therefore, the other end of the hook 2 is formed with a through hole 3 for inserting the band in a folded shape and a guide hole 5 for guiding the band in the opposite direction in a folded shape.

That is, the through hole 3 is formed by two rows of openings 3a, 3b on the inlet side and the outlet side of a substantially rectangular shape penetrating from the back surface (lower surface in FIG. 1) to the front surface of the hook 2,
A band hooking portion 4 having a substantially rhombic cross section is formed between the openings 3a and 3b. Therefore, the seat holding band 1
The other end is inserted from the opening 3a on the inlet side of the center, hung so as to wind around the band hooking portion 4, and pulled out from the opening 3b on the outlet side of the outer side.

On the other hand, the guide hole 5 has a band-shaped inlet 5a on the back side of the hook 2 and a substantially V-shaped cross section having a draw-out opening 5b on the longitudinal end face of the hook 2. Therefore, the sheet holding band 1 pulled out from the through hole 3
The sheet is further inserted into the guide hole 5 so as to be folded back in a substantially U-shape in the opposite direction, and then pulled out in a direction substantially parallel to the tension direction of the sheet holding band 1. As a result, the substantially U-shaped folded-back portion 1b is folded back in the opposite direction.
Are hooked on the corner 3c of the opening 3b on the outlet side of the through hole 3 and the corner 5c of the inlet 5a of the guide hole 5, respectively, and are superposed on the flat surface on the main body side 1a of the sheet holding band 1.

Further, as shown in FIG. 4, a concavo-convex strip 6 having a substantially corrugated cross-section extending in the longitudinal direction of the band is formed on the front surface side (upper surface in FIG. 1) of the band hooking portion 4,
As a result, the hooking force of the sheet holding band 1 with respect to the corners on the front surface side of the band hooking portion 4 is increased. In addition, as shown in FIG. 5, the longitudinal direction of the band is similarly extended to the flat portion between the corner 3c of the opening 3b on the outlet side of the through hole 3 and the corner 5c of the inlet 5a of the guide hole 5. An uneven strip 7 having a substantially corrugated cross section is formed in the inward direction, whereby both corners 3c,
The retaining force of the sheet holding band 1 with respect to 5c is increased.

Incidentally, the through hole 3 and the guide hole 5 described above.
Is set to be slightly wider than the band width of the sheet holding band 1 as a whole, but the outlet 5b of the guide hole 5 is
As shown in FIG. 2, the width is set to be equal to the band width, which prevents lateral displacement of the sheet holding band 1.

The seat holding device of this embodiment is constructed as described above. As shown in FIG. 6, when the folding seat 21 is stored and held, the seat back 23 is folded on the seat cushion 22, and Further, the seat cushion 23 is erected in a flip-up shape on the side body 24 side. In this state, after hooking the hook 2 on the assist grip 25 of the side body 24, as shown in FIG.
By pulling out the pull-out end portion 1c of the sheet holding band 1 pulled out from the through hole 3, the band can be tightened to a predetermined tension state and the sheet can be held in an upright state.

In the sheet holding device of this embodiment, after the sheet holding band 1 is inserted into the through hole 3 of the hook 2 in a folded shape, the folded portion is further passed through the guide hole 5 and folded back in the opposite direction. In the tensioned state of the band in which the folded sheet is stored and held, the substantially U-shaped folded-back portion 1b is caught on the corner 3c on the outlet side of the through hole 3 and the corner 5c on the inlet side of the guide hole 5. And causes a reaction force.

Therefore, even when the seat holding band 1 is repeatedly moved in the pulling direction and the slacking direction as the seat moves up and down due to vibration of the vehicle body while the vehicle is running, the substantially U-shaped folded-back portion 1b has a corner. The hooked state with respect to the portions 3c and 5c is maintained. That is, the holding belt 1 is vibrated.
Even if slack occurs as shown by the dotted line in FIG. 1, the reaction force holds the substantially U-shaped folded-back portion 1b of the sheet holding band 1 in a state in which it is difficult to move with respect to the hook 2, so that the sheet holding band is not moved. The occurrence of loosening due to the pulling out of the hook 1 from the hook 2 is suppressed, and the seat can be reliably held in the storage position.

Further, in this embodiment, the sheet holding band 1
Since the corner portions 3c, 5c on which the U-shaped portion of the above is hooked are formed in a substantially corrugated shape, a stronger hooking force (biting) can be obtained. Further, in this embodiment, the width of the outlet 5b of the guide hole 5 is set equal to the band width to prevent the drawer end 1c of the sheet holding band 1 from laterally shifting as shown by the dotted line in FIG. When the lateral displacement occurs, the sheet holding band 1 may be less likely to be caught on the corners 3c and 5c and loosen, but according to the present embodiment, such a problem can be solved. .

On the other hand, when loosening the sheet holding band 1, if the hook 2 is tilted away from the sheet holding band as shown in FIG. Move against. That is, according to the present embodiment, the length adjusting work for tightening and loosening the sheet holding band 1 can be easily performed.

In this embodiment, the through hole 3 is provided with the hook 2
Although it is configured to open on the front surface side, the front surface side may be closed. Further, the direction of the outlet 5b of the guide hole 5, that is, the direction in which the sheet holding belt 1 is pulled out from the guide hole 5 does not need to be parallel to the tension direction of the holding belt 1, and may be inclined.

[0023]

As described in detail above, according to the present invention,
Despite the omission of the magic fastener, it is possible to hold the seat in the initial position by suppressing the slack in the seat holding band in use, and since the magic fastener is omitted, the band length adjustment work Can be done easily.
