DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a seat device provided in a vehicle compartment having a floor tunnel, and more particularly to a vehicle seat device capable of improving passenger comfort and luggage space in the vehicle compartment. .

[0002]

2. Description of the Related Art Today, in the automobile industry, various seat devices have been proposed together with a vehicle cabin structure for the purpose of improving the livability in a vehicle cabin. One example is disclosed in JP-A-8-276.
As can be seen in Japanese Patent Publication No. 774, the seat body is mounted on a side wall rail fixed to the body side panel via a hinged support so as to be adjustable in position, and a folding leg is provided on one side of the lower surface of the seat body. Structure. When the seat is used, only one of the folding legs is erected on the floor. When the seat is not used, the leg is folded toward the lower surface of the seat body, and the seat body itself is folded toward the side panel via the hinge of the support. In this structure, when the seat is in use, only the folding leg is erected on the floor, so that a large gap is secured between the seat body and the floor. For this reason, the occupant in the rear seat can put his / her feet in the gap and sit down comfortably or can use the gap as a luggage space for luggage.

[0003]

Even in the conventional structure as described above, the legs provided on the lower side of the seat body obstruct, and cannot be sufficiently satisfied in the following points. First, the occupant on the rear seat side can get a relaxed state by putting his / her feet into the gap below the seat body, but when the feet are moved in the left-right direction, the feet become It is easy to collide, making it insufficient in habitability. This is also the case when trying to place luggage in the gap,
The legs are in the way, so you can't put too much luggage or it's hard to get in and out. Secondly, when using the gap as a luggage base, it is often necessary to open the adjacent door and put in / out the luggage. In such a case, it is necessary to perform the operation smoothly because the side wall rails and supports are in the way. Can not. Of course, a large space can be obtained by folding the seat body together with the legs via the support, but such a switching operation requires power and time and is not easy.
Third, in a passenger car cabin design, a passenger vehicle generally has a floor tunnel portion that is located substantially at the center of the vehicle body in the width direction and extends in the vehicle front-rear direction while standing up from the floor surface. . And the seat body equipped there is arranged in a pair on both sides of the floor tunnel part. In this structure, a center console may be provided at the upper part of the floor tunnel part, but other than that, it is not used, and the width dimension of each seat body is restricted by the presence of the floor tunnel part, There are inherent defects such as.

The present invention has been developed in view of the above background. It is an object of the present invention to provide an automobile seat device which has a relatively simple structure and a structure capable of obtaining an optimum livability and a luggage space by eliminating the above-mentioned problems. Still other objects will be sequentially clarified in the contents described below.

[0005]

In order to achieve the above object, the present invention, as illustrated in the drawings, is located substantially at the center of the vehicle body in the width direction, and extends in the front-rear direction of the vehicle body while standing up from the floor surface 14. The seat body 13 is inserted into the vehicle interior having the floor tunnel portion 12 through a seat slide 22 (same as a slide mechanism) in which a vehicle body side rail 23 and a seat side rail 24 are slidably fitted. In the car seat device that is installed so that the front and rear position can be adjusted,
The seat body 13 is a part of the floor tunnel portion 12.
The vehicle body-side rail 23 provided along the upper side rising from the floor surface 14 and the seat-side rail 24 provided on one side of the lower portion of the seat body 13 adjacent to the floor tunnel portion 12 through the floor surface. It is configured to be held in a cantilevered state at a predetermined height from 14 and to be adjusted in the front-rear position along the floor tunnel portion 12.

In the above structure, since the seat body 13 is supported in a cantilever manner with respect to the floor tunnel portion 12, the leg portion on the lower side of the seat which has been used in the conventional structure is eliminated, and the lower portion of the seat is relatively positioned. A large space can be secured. And it is excellent in the following points specifically. From the viewpoint of comfort in the passenger compartment, the seat body 13 is supported by the floor tunnel portion 12 in a cantilever manner, and the floor surface 1
Since a space is secured between the vehicle and the occupant, even when an occupant such as a rear seat puts his or her feet in the space and moves the space, the occupant is less restricted and can relax more.
In addition, when loading and unloading luggage into and from the space, it is possible to immediately load and unload luggage from the state where the adjacent door is opened. From the viewpoint of the cabin space, the structure in which the seat slides 22 are arranged along the floor tunnel portion 12 makes it possible to effectively use the mounting space. At least the width of the seat cushion 17 can be increased, and the interior of the vehicle cabin can be improved because the floor tunnel 12 is covered and hidden by a part of the seat body 13.

The present invention is more preferably embodied as follows. First, the seat body 13 has a configuration in which a corresponding portion of the seat cushion 16 adjacent to the floor tunnel portion 12 is formed in a stepped shape 17a covering the corresponding portion of the floor tunnel portion 12. In this structure, the floor tunnel portion 12
Is structurally covered to obtain novelty as well as the appearance of the vehicle interior. Since the step 17a constitutes the side of the seat, there is no possibility that the sheet holding characteristic is impaired. As for the vehicle seat structure, the presence of the portion corresponding to the step 17a allows the seat width to be increased as compared with the conventional seat structure. Second, the seat body 13
Are installed independently on the left and right sides of the floor tunnel portion 12, respectively, and a part of the floor tunnel portion 12 is almost completely covered by the stepped shape 17a of each seat body 13. With this structure, the front and rear positions of the seat bodies 13 on both sides are similarly adjusted, and the stepped shape 17a of each seat body 13 makes the corresponding portion of the floor tunnel section 12 invisible. Can definitely be improved. Third, the seat slides 22 are provided in pairs. One of the seat slides 22A is disposed along the upper surface of the floor tunnel portion 12, and the other seat slide 22B is disposed on the side surface 12 of the floor tunnel portion 12.
This is a configuration arranged along b. In this structure,
When the load of the seat body 13 is increased by both the seat slides 22A, 22
Since it is supported by B, even if it is a cantilever type support structure, it is possible to satisfy the design strength relatively easily and easily.

And stable support in terms of strength can be achieved even with a cantilever.

In the structure of the above embodiment, the seat-side rail 24 of the first slide portion 22A and the second slide portion 22
Although the structure in which the seat-side rails 24 of B are integrally formed on the common substrate 25 has been disclosed, they may be separately formed and fixedly supported on the cushion frame 16 side. Further, the seat frame structure and the seat slide structure can be variously modified based on this form. Although the case where the seat slide 22 is constituted by the first sheet slide portion 22A and the second sheet slide 22B has been described, the seat slide 22 may be constituted by only one of the sheet slide portions 22A and 22B. However, in the case where it is constituted by the two sheet slide portions 22A and 22B, stable support can be performed in terms of strength as described above.

[0017]

As described above, according to the present invention,
Since the legs are eliminated from the lower side of the seat body used in the conventional apparatus, and a space (gap) can be secured under the seat body, the following effects can be obtained. In view of the comfort of the passenger compartment, the seat body is supported in a cantilevered manner in the floor tunnel portion, and a space is secured between the seat body and the floor surface. It becomes difficult to be regulated when putting in and moving,
You can relax more. In addition, when loading and unloading luggage into and from the space, it is possible to immediately load and unload luggage from the state where the adjacent door is opened. Due to the spatial nature of the cabin, the structure in which the seat slides are arranged along the floor tunnel portion makes it possible to effectively use the mounting space, and at least the seat cushion of the seat body as compared with the conventional structure. It is also possible to increase the width dimension of the vehicle, and it is also possible to cover and cover the floor tunnel portion with a part of the seat body, thereby improving the appearance of the vehicle interior.
