Description

  The present invention relates to a flat sheet capable of forming a flat floor surface on the front side of a cargo compartment floor when the sheet is moved forward.

In a vehicle such as an automobile, a flat sheet is known in which a sheet provided on the front side of the cargo compartment is tilted forward and a flat floor can be formed on the front side of the cargo compartment floor. In such a flat seat, when the seat back is rotated forward, the lower end of the seat back rotates upward as the seat back is tilted forward, and the rear end of the seat back when the seat back is in a horizontal position Reaches the position facing the front wall of the cargo floor. For this reason, it is necessary to provide a gap between the rear end of the rotating seat back and the front end of the cargo floor so that the gap is closed in a state where the seat back is tilted down. A rotating plate extending downward along the back surface of the seat back is attached to the lower end of the seat back (see Patent Document 1).
JP 2002-274235 A

However, in the above-described prior art, the rotating plate is urged upward in a state where the sheet is tilted. For this reason, since the rotating plate faces downward when the seat is erected, it is necessary to form a space on the lower side of the seat so as to avoid the rotating plate, resulting in an increase in the seat height. There is a problem that the cabin space becomes narrow.
Further, when a reclining mechanism is provided at the hinge portion of the seat back via a bracket, it is necessary to provide an escape portion on the rotating plate in order to avoid a portion extending in the width direction of the bracket. For this reason, there is a problem that the inside of the gap can be seen from the escape portion or the reclining mechanism can be seen to impair the appearance.
When the seat is raised while the rotating plate attached to the lower end of the seatback is on the floor, there is a problem that the seatback cannot be raised because the rotating plate is caught.

  Therefore, the present invention can lower the seat height to widen the cabin space, can smoothly tilt the seat back to the front side, improve the appearance in the state of being tilted forward, and can stand up smoothly. An object of the present invention is to provide a flat sheet that can be used.

In order to achieve the above object, the invention described in claim 1 supports a seat back (for example, the seat backs 11R and 11L in the embodiment) so that the seat back can be moved forward, and the seat back is moved forward when the seat back is moved forward. In a flat sheet (for example, the rear row seat 1 in the embodiment) that is set so that the cargo compartment floor (for example, the rear floor 8) and the back surface of the seat back that are arranged behind the floor are substantially flush with each other, the seat A support shaft (for example, a hinge member G in the embodiment) extending in the width direction is provided on the back surface of the back, and a front end is supported by the support shaft. When the seat back is tilted forward, the seat back and the cargo compartment floor A movable flap (for example, the movable flap 14 in the embodiment) that covers a gap formed between the movable flap and the rear end of the movable flap is provided. A strap (for example, the embodiment) that connects a vehicle body member (for example, the bracket 5 in the embodiment) positioned between the inner sides and restricts the pivoting of the movable flap from the horizontal position when the seat back is tilted forward. A strap 31) is provided.
With this configuration, when the seat back is tilted forward, the movable flap is displaced upward along with this and the gap between the seat back and the rear cargo compartment floor is covered to make the cargo compartment floor flat. . At this time, since the movable flap is restricted from rotating upward by the strap, it is possible to prevent the movable flap from being buffered on the cargo floor behind the seat back when the seat back is raised from the forward-turned state.

The invention described in claim 2 is characterized in that urging means (for example, the torsion spring 17 in the embodiment) for urging the movable flap toward the back surface of the seat back is provided.
With this configuration, the movable flap can always be pressed downward when the seat back is turned to the upright state.

According to a third aspect of the present invention, the seat back includes a back body (for example, the back body 13 in the embodiment) provided with a notch (for example, the notch 12 in the embodiment) in a lower corner portion, and the notch. Provided with a reclining mechanism (for example, the reclining mechanism 6 in the embodiment), a bracket for fixing the reclining mechanism to a vehicle body (for example, the bracket 5 in the embodiment), and the movable flap as a back body and the The strap is disposed so as to cover the reclining mechanism, one end of the strap is supported by the rear end of the movable flap, and the other end is supported by the bracket.
With this configuration, when the seat back is tilted forward, the movable flap whose front end is pivotally supported by the support shaft extending in the width direction on the back surface of the seat back is disposed in the notch portion of the back body and the notch portion. Brackets and reclining mechanisms can be covered.

According to the first aspect of the present invention, when the seat back is tilted forward, the movable flap can be displaced upward accordingly and cover the gap between the seat back and the rear cargo floor. Therefore, the inside can not be seen and the appearance can be improved.
Further, since the movable flap is restricted from rotating upward by the strap, it is possible to prevent the movable flap from being buffered on the cargo floor behind the seat back when the seat back is raised from the forward-turned state. Therefore, there is an effect that the seat back can be operated smoothly even when the seat back is moved forward.
According to the second aspect of the present invention, since the movable flap can be always pressed downward, even when the seat back is turned to the upright state, even if the lower end of the seat back turns downward, the movable flap After the lower end abuts on the lower floor, it rotates away from the back of the seat back and does not follow the seat back any further. Therefore, the lower end of the movable flap is taken into consideration to escape to the floor surface. There is no need to provide a part or the like. Therefore, the seat height can be lowered correspondingly, and the vehicle interior can be widened.
According to the invention described in claim 3, when the seat back is tilted forward, the movable flap whose front end is pivotally supported on the support shaft extending in the width direction on the back surface of the seat back is formed in the notch portion of the back body and the notch portion thereof. Since the bracket and the reclining mechanism which are arranged can be covered, there is an effect that it is possible to improve the appearance when the seat is moved forward.

Therefore, the left and right seat backs 11R, 11L brought forward are superimposed on the seat cushion 10.

FIG. 2 is a top view of a state in which both the left and right seat backs 11R and 11L of the rear row seat 1 are rotated forward and stacked on the seat cushion 10. As shown in FIG. 2, both the left and right seat backs 11R, 11L that are brought forward are substantially flush with the rear floor 8 that constitutes the upper part of the luggage compartment disposed behind the seat backs 11R, 11L. It is set to be.
A back plate 9 made of a material having a certain degree of rigidity is attached to the rear surfaces of the left and right seat backs 11R, 11L in a range from the upper part of the seat backs 11R, 11L to a portion that covers the bracket 5.

Here, the seat backs 11 </ b> R and 11 </ b> L have a back body 13 having a notch 12 at a lower corner portion and a bracket 5 having the above-described reclining mechanism 6 disposed in the notch 12.
A hinge member G extending in the width direction is provided on the lower edge of the back plate 9 for each of the seat backs 11R and 11L, and a movable flap 14 formed of the same material as each of the back plates 9 is provided on each hinge member G. Each is rotatably supported.
The movable flap 14 covers the lower edge of the back body 13 of each of the seat backs 11R and 11L and the bracket 5 having the reclining mechanism 6 from the top including the notch portion 12, and extends to the vicinity of the front edge of the rear floor 8. It has a width. The rear floor 8 is a member that is slightly wider than the width dimension of the left and right seat backs 11R, 11L in the vehicle width direction, and is a front edge of a portion protruding sideways from the side portions of the left and right seat backs 11R, 11L. A pair of corner floors 15, 15 are arranged on the left and right at the corner with the side edge of the movable flap 14. Here, the corner floors 15 and 15 are provided so as to be foldable with the rear end as a fulcrum with respect to the rear floor 8, and are integrated with the rear floor 8 by bonding a cloth material (not shown).

  Therefore, as shown in FIGS. 3 and 4, the left and right seat backs 11R, 11L that have been brought forward are substantially flush with the rear floor 8 that constitutes the upper part of the luggage compartment disposed behind the left and right seat backs 11R, 11L. Then, on the front side of the rear floor 8, the back plates 9, 9 of the left and right seat backs 11R, 11L and the movable flaps 14 connected to the back plates 9 by hinge members G are slightly attached to the rear floor 8. A flat floor surface is formed with a gap.

FIG. 5 shows the vicinity of the right bracket 5 and specifically is a cross-sectional view in the front-rear direction of the notch 12 on the lower right side of the seat back 11R. In the following description, the vicinity of the right bracket 5 will be described as an example. However, since the same applies to the left bracket 5, the same portions are denoted by the same reference numerals and description thereof is omitted.
The movable flap 14 rotatably supported on the rear edge of the back plate 9 via the hinge member G is provided with a bent portion 16 that falls slightly downward on the rear edge. Here, a torsion spring 17 is provided on the hinge member G of the movable flap 14. The torsion spring 17 urges the movable flap 14 in a downward pressing direction, and the back surface of the seat backs 11R and 11L existing on the front side of the notch portion 12 of the seat backs 11R and 11L in the forwardly tilted position in FIG. The rotation is restricted in a state where is pressed.
A bracket 5 fixed to the floor panel 2 is provided below the movable flap 14 and in a space formed by the notch 12 of the back body 13 of the seat back 11R, 11L. A reclining mechanism (shown by a chain line) 6 having a shaft portion J of the seat backs 11R, 11L coaxially is provided at the upper part.

  The bracket 5 has a shape in which the upper side has an arc shape and the lower side widens, and a peripheral rib 21 is provided on the peripheral edge of the side plate 20 toward the inside. A plurality of ribs 22 are formed radially around the shaft portion J of the seat backs 11R and 11L on the inner surface of the side plate 20, and a gap 23 is formed between the peripheral ribs 21 and the floor panel 2 at the rear lower end. Yes. Corresponding to the arcuate shape of the upper part of the bracket 5, an arcuate recess 24 is formed at the rear end of the seat back 11R, 11L so that it does not buffer with the bracket 5 even if the seat back 11R, 11L rotates. ing.

As shown in FIG. 6, a hook 30 that protrudes inward on the inner surface of the side plate 20 is provided at the lower portion of the rear portion of the bracket 5. The hook 30 is formed in a vertically long cross section and is used to attach a strap 31 described later.
As shown in FIG. 7, a cylindrical locking cylinder 32 projects from the back side of the bent portion 16 of the movable flap 14, and a strap 31 is connected between the locking cylinder 32 and the hook 30 of the bracket 5. Has been. Four ribs 33 ′ are provided around the locking cylinder 32 for reinforcement.
The strap 31 is a belt-like member, and is provided with a plate-like attachment piece 29 at one end. The attachment piece 29 is formed with a hole 34 that engages with the engagement cylinder 32 of the movable flap 14. The other end of the strap 31 is provided with a ring portion 35 that is engaged with the hook 30 of the bracket 5.
In this way, the hole 34 of the attachment piece 29 provided at one end of the strap 31 is covered with the locking cylinder 32 of the movable flap 14, and the hole 36 of the push nut 33 is press-fitted into the locking cylinder 32. The attachment piece 29 is attached to the four ribs 33 ′ by the push nut 33. Further, the ring portion 35 provided at the other end of the strap 31 is locked to the hook 30 of the bracket 5.
Here, in the state where the seat backs 11R and 11L are tilted forward, the strap 31 is stretched downward from the locking cylinder 32 on the back side of the movable flap 14, and faces the inside of the bracket 5 from the rear portion of the peripheral rib 21. It is inserted from the gap 23 and attached to the hook 30 of the bracket 5.

According to the above embodiment, when the seat backs 11R and 11L are moved from the standing state to the forwardly tilted state, the movable flaps 14 are gradually displaced upward along with the movable flaps 14. Since it is urged downward by the torsion spring 17 provided on the hinge member G, it does not get up and does not hinder the forward operation of the seat backs 11R, 11L. Further, since the movable flap 14 is biased with respect to the seat backs 11R and 11L, the angle of the movable portion can be made flat with respect to the seat backs 11R and 11L even when the seat backs 11R and 11L are tilted forward. .
As shown in FIG. 9, in the forward-turned state in which the seat backs 11 </ b> R and 11 </ b> L are superimposed on the seat cushion 10, the movable flap 14 is in a horizontal posture, but the upward protrusion is reliably restricted by the strap 31. Therefore, the cargo compartment floor can be made flat together with the back plates 9 and 9 and the rear floor 8.
Further, since the movable flap 14 is restricted from rotating upward by the strap 31, when the seat backs 11R and 11L are raised from the forward-turned state next, the rear floor 8 behind the seat backs 11R and 11L is provided. It is possible to prevent the front edge from being buffered. Further, it is possible to prevent unnecessary access to a structure such as the bracket 5 disposed in the gap between the seat backs 11R and 11L and the cargo floor.
Here, not only when the seat backs 11R and 11L are both brought forward at the same time as described above, but also when only the left seat back 11L is brought forward as shown in FIG. Even when only the back 11 </ b> R is brought forward, the one strap 31 that has been brought forward can function to restrict the upward displacement of the movable flap 14.

In this way, the movable flap 14 covers the notch 12 of the back body 13 and the bracket 5 and the reclining mechanism 6 disposed in the notch 12 when the seat backs 11R and 11L are tilted forward, and the rear rear floor. It is possible to reliably close the gap between the two and improve the appearance. Therefore, the inner side is not seen from the notch 12 of the back body 13 and the appearance can be improved.
Of course, even when the seat backs 11R and 11L are in the standing state, the bracket 5 is covered from the rear side by the movable flap 14 that is reversely folded with the rotating end abutting against the floor panel 2, so that the notch 12 of the back body 13 is provided. Of course, the bracket itself cannot be seen from the rear, and the appearance can be improved in this respect.

Next, when the seat backs 11R and 11L are raised to stand up, the movable flaps 14 that rotate together with the seat backs 11R and 11L are urged downward by the torsion springs 17, so the lower ends of the seat backs 11R and 11L Even if the wrap around the lower side, the lower end of the movable flap 14 comes into contact with the lower floor panel 2 and then turns away from the back of the seat backs 11R and 11L. It does not rotate following the backs 11R and 11L. Therefore, it is not necessary to provide a relief or the like on the surface of the floor panel 2 in consideration of the downward movement of the movable flap 14, and the seat height can be lowered by that much and the vehicle interior can be widened.
In addition, this invention is not restricted to the said embodiment, For example, each hinge member G is not what was continued in the vehicle width direction, and may be comprised by dividing and arrange | positioning to several hinge members. .
