Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle seat that can be folded to expand a space for loading luggage.

[0002]

2. Description of the Related Art A folding seat for a vehicle of this type is disclosed in, for example, Japanese Utility Model Laid-Open No. 6-50963. This is because the front part of a support member on the lower side of the seat, which is provided on the rear side of the seat cushion so that the seat back can be raised and lowered, is supported on the floor of the vehicle so as to be rotatable about the left-right axis, and is rotated to the rear part of the support member. When the seat cushion is raised against the floor, the movably installed folding legs fall along the lower surface of the seat cushion, and when the seat cushion is laid down on the floor, the folding legs rise up against the lower surface of the seat cushion and lift the rear part of the support member. The link mechanism is linked with the ups and downs of the seat cushion so as to support it. An under cover provided on the lower side of the seat cushion that is exposed to the outside in a folded state is provided with an opening for allowing a folding leg to come in and out.

Further, in the technique disclosed in Japanese Patent Laid-Open No. 6-234337, when the rear seat is not in use, the rear seat is folded and pivoted to the side so as to be flipped up and supported, and the seat lower side for storing the legs. A cover and a cover plate are provided on the open surface of the storage section formed in 1., and the cover plate is configured to be fixed to the leg body and openable and closable. Neither of these conventional techniques has a function of sliding the seat in order to adjust the position of the seat in the front-rear direction.

[0004]

In the first prior art described above, when the seat is raised with respect to the floor, the folding legs are accommodated in the undercover on the lower surface of the seat cushion through the opening. In order to smoothly move the legs in and out, it is necessary to provide a considerable gap between the legs and the interior of the folding legs and part of the under cover, so the bottom of the seat cushion exposed on the outer surface looks good. There is a problem that there is no. This problem can be solved by using a cover plate that is fixed to the leg body and can be opened and closed, as shown in the second prior art.

However, in the case where the seat is slidable in order to adjust the position of the seat in the front-rear direction, this opening has a large length in the front-rear direction, whereas the second prior art cover plate is used. Considering the locking of the tip of the leg to the vehicle floor during storage and the storage when not in use, the length cannot be longer than the length of the leg. For this reason, in the case where the seat is slidable, the opening cannot be completely closed by the cover plate provided on the leg, and the appearance is deteriorated. Furthermore, since the opening cannot be closed completely, a gap is created, and foreign matter such as dust easily enters the undercover through the gap, and this foreign matter goes out of the undercover and causes dirt in the vehicle interior. It also becomes. An object of the present invention is to solve such a problem and to improve the appearance of the lower side of a seat cushion that is exposed to the outside when a seat having a longitudinal position adjustment function is raised with respect to the floor. To do.

[0006]

In a folding seat for a vehicle according to the present invention, one side portion of a lower rail slidably supporting a seat cushion is rotatably supported on a floor of a vehicle and the other side of the lower rail is supported. One end of the folding leg is rotatably attached to the section, the lower side of the lower rail is covered with a covering shield having an opening corresponding to the folding leg, and the folding leg is raised and lowered in conjunction with the lower rail raising and lowering, and a seat cushion is provided. When the seat cushion is raised against the floor, the folding legs are stored in the covered shield, and when the seat cushion is folded down on the floor, the folding legs stand up through the opening and support the other side of the lower rail on the floor. And a shutter guide provided along both sides of a part of the opening that is opposite to the pivotal support with respect to the floor. The slide shutter is slidably guided and supported, and the front end of the slide shutter is connected to the end of the lower rail that is on the folding leg side so that a part of the opening can be opened and closed. When the seat cushion is provided and the seat cushion is raised, the leg cover is arranged so as to be continuous with the slide shutter and to close the opening portion on the pivotal support side of the lower rail. Since both the leg cover and the shutter guide are attached to the lower rail, if the upper rail is slid with respect to the lower rail to adjust the seat position, the leg cover and the shutter guide move integrally with the covering shield.

The above-described slide shutter has a large number of rod-shaped elements that are orthogonal to the shutter guide and are connected by a flexible thin connecting portion, and is flexible enough to be rolled up at least only in the sliding direction. It is preferable.

It is preferable that the leg cover is a plate having a width slightly narrower than the opening and is fixed to one side of the folding leg so that the outer surface of the leg cover is aligned with the outer surface of the covering shield when the seat cushion is raised.

In each of the above-described vehicle folding seats, an auxiliary cover is further attached near the pivotal support for the floor of the lower rail so that the portion closer to the pivotal support than the leg cover of the opening is closed with the seat cushion raised. Preferably.

The above-mentioned auxiliary cover is located in the opening with a slight gap on both sides, the outer surface of which is aligned with the outer surface of the covering shield, and the auxiliary cover is fixed in parallel with the lower rail by a guide member fixed near the pivotal support of the lower rail. It is preferable to use a slide member that is guided and supported so as to be movable in a distance and urged by a spring toward the slide shutter.
