DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a horizontally flip-up type seat mounted on a vehicle such as an automobile.

[0002]

2. Description of the Related Art In vehicles such as wagons, a rear-leaching seat (also referred to as a space-up seat) is provided on a rear seat for the purpose of diversifying a luggage compartment and improving storage space.
(See Japanese Utility Model Application Laid-Open No. 6-27303). This seat is, as shown in FIG. 3, a seat back (11b).
The entire seat (11) is flipped up to the side of the vehicle body with the back tilted, and the holding band (14) attached to the seat (11) is hooked on the assist grip (15) to maintain the flip-up posture. is there.

[0003] In this type of seat, if the seat flaps during traveling, an abnormal noise is generated or the strength of the seat component is concerned. Therefore, normally, as shown in FIG. 4, not only the holding by the holding band (14), but also a part of the seat (11) is caused to interfere with the inner side surface (12) of the vehicle body such as a body or an interior trim and the like. ) Prevents flapping.

[0004]

SUMMARY OF THE INVENTION Such a sheet (1
The interference state between 1) and the inner surface of the vehicle body (12) must be maintained at all times even after the holding band is hooked on the assist grip. Therefore, when the seat is flipped up, as shown by the arrow in FIG. 4, the holding band (14) is strongly pulled up while pressing the seat cushion (11a) to the side of the vehicle body to assist the hook (14a) at the tip thereof. Must be hooked on grip (15). However, such an operation is troublesome, and the usability is greatly deteriorated. In the design stage, when determining the length of the holding band (14), not only the distance from the seat to the assist grip but also the elasticity (softness) of the seat must be taken into consideration. difficult.

Accordingly, an object of the present invention is to improve the operability at the time of storing the flip-up type seat and to rationalize the design.

[0006]

In order to achieve the above object,
In the present invention, the entire seat is flipped up to the side of the vehicle body in a state where the seat back is tilted backward, and the posture is held by the holding band locked to the inner side surface of the vehicle body. The flip-up seat is set to be held at a position immediately before it interferes with the inner surface of the vehicle body, and when the back door is closed, the seat back top of the flipped-up sheet interferes with the back door. .

With the above arrangement, the seat, which was in an unstable state only by the holding force of the holding band before the back door was closed, is pushed toward the center of the vehicle body by the interference with the back door after the back door is closed. Under the pressure, it is slightly displaced in the direction. As a result, the holding band is in a tension state, so that the entire sheet can be held firmly. Also,
If the length of the holding band is set to be held immediately before the jumped-up sheet interferes with the inner surface of the vehicle body, it is not necessary to strongly pull the band when locking the holding band to the assist grip, etc. Usability is also good.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The structure of a flip-up seat according to the present invention will be described below with reference to FIGS.

As shown in FIGS. 1 and 2, the sheet (1)
Is a pivot (3) provided along the front-rear direction below the seat cushion (1a) and near the inner surface (2) of the vehicle body.
To be rotatably supported. Seat cushion (1a)
A holding band (4) is attached to the bottom surface of the vehicle. When the seat (1) is retracted, the hook (4a) at the tip of the holding band (4) is attached above the inner side surface (2) of the vehicle body. The sheet (1) is held in a flip-up posture by being hooked on (5). As shown in FIG. 2, when the seat (1) is flipped up, the holding band (4) comes into contact with any part of the inner surface (2) of the vehicle body, such as the body or the interior trim. Set to the length just before the interference (the chain double-dashed line in the figure is the flip-up position of the sheet (11) in the conventional product).

When the sheet (1) is stored, that is,
When the seat back (1b) is tilted backward and the entire seat (1) is flipped up, the components of the back door (6) in which the top of the seat back (1b) is in the closed position, such as the back door pillar (6a). Installed to interfere. Therefore, when the back door (6) is opened to some extent (represented by a two-dot chain line in FIG. 1), the seat back (1b) does not contact the back door pillar (6a), but the back door (6)
When the seat back is completely closed, the seat back (1b) comes into contact with and interferes with the back door pillar (6a) (the interference area at this time is indicated by oblique lines (P)), and the seat (11) is in the back door (6). From the center of the vehicle.

The sheets are stored in the following procedure.
That is, first, the seat back (1b) is tilted backward similarly to the conventional product, and the entire seat (1) is flipped up while facing the inner surface (2) of the vehicle body while rotating about the pivot (3). (1a) Fold the legs (18: see FIG. 3) attached to the bottom, and further hold the band (4)
Hook the hook (4a) at the tip on the assist grip (5). Then, the back door (6) is closed to cause the vicinity of the top of the seat back (1b) to interfere with the back door pillar (6a).

As a result, before the back door (6) is closed, the sheet (1), which was in an unstable state only by the holding force of the holding band (4), receives a pressing force from the back door (6) and slightly. As a result, the holding band (4) is in a tensioned state, so that the entire seat (1) can be firmly held, and the seat (1) during traveling can be prevented from fluttering. Becomes possible. Retaining band (4)
Is set to a length just before the seat (1) interferes with the inner side surface (2) of the vehicle body, so that when the holding band (4) is hooked on the assist grip (5), the band does not need to be strongly pulled. Also, the usability is good.

In other words, the present invention enables the holding band (4) to be secured to the assist grip or the like with a margin while the vehicle flutters while the vehicle is stopped or the like. When driving is a problem,
The back door (6), which is always closed during running, is used to prevent the seat (1) from fluttering.

With this configuration, when determining the length of the holding band (4), only the distance from the seat (1) to the assist grip (5) needs to be taken into consideration. Since it is not necessary to consider the softness of 1), the design is facilitated.

It is sufficient that the tip of the holding band (4) can be securely locked to the inner side surface (2) of the vehicle body. In this limit, the locking structure between the holding band (4) and the inner side surface (2) of the vehicle body. Is optional. That is, not only the combination of the hook (4a) and the assist grip (5) but also another appropriate combination that is easily detachable can be employed. The position of the locking structure is also arbitrary, and the locking portion (band side) and the locked portion (vehicle side) may be engaged behind the assist grip (5) in the figure. However, if the assist grip (5) is used as the locked portion as described above, the distance (L) from the locked position to the interference portion (P) can be made sufficiently large, so that the wrap amount is slightly reduced. Even if it is large, the bending force of the entire seat (1) can absorb the pressing force from the back door (6), and the advantage that the holding band (4) is not excessively tensioned can be obtained.

In the above description, the lateral opening / closing type back door (6) rotated about the vertical axis by the hinge (7) attached to the side of the vehicle body is exemplified. Is optional, and is similarly applicable to an up-and-down opening / closing type back door that is rotated up and down around a horizontal axis by a hinge attached to the upper part of the vehicle body.

[0017]

As described above, according to the present invention, since the top of the seat back of the seat in the flipped up position interferes with the back door at the closed position, the entire seat is firmly held during running to prevent the seat from fluttering. It can be reliably prevented.
In addition, the length of the holding band is set so that the flipped-up sheet is held at a position immediately before it interferes with the inner surface of the vehicle body, so there is no need to strongly pull the band when locking the holding band to the assist grip or the like. Also, the usability is good. Further, when determining the length of the holding band, only the distance from the seat to the assist grip needs to be considered, and there is no need to consider the softness of the seat as in the conventional product, so that the design is facilitated.
