Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle seat in which a rear seat can slide to the rear end of a vehicle without being hindered by a tire house.

[0002]

2. Description of the Related Art In recent years, in order to be applicable to a multipurpose use of an automobile, an automobile seat capable of moving a rear seat to the rearmost side of a luggage compartment is disclosed in, for example, Japanese Utility Model Laid-Open No. 1-152838, As already proposed in Japanese Patent Application Laid-Open No. Hei 7-108864, in this type of conventional car seat, when the rear seat is moved to the rearmost part of the car, the rear wheel tire house protruding into the luggage compartment. In order to avoid this effect, there is a problem that the shape of the rear seat and the trajectory of the rail for guiding the seat are restricted.In addition, it is necessary to slide the rear seat to completely avoid the wheel house. A complicated and expensive mechanism and complicated operation procedures are required, which makes it difficult to apply to general vehicles.

[0003]

SUMMARY OF THE INVENTION The present invention solves the above-mentioned conventional problems and has a simple structure and allows the rear seat to be moved to the rearmost side of the vehicle without being restricted by the seat shape or rail trajectory. It has been completed with the objective of providing an automobile seat that can slide a long distance, and can also perform a slide operation of the seat in an easy procedure, and also has an excellent seat folding function. Things.

[0004]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, a vehicle seat according to the present invention is provided on a body floor surface of a luggage compartment in which a tire house is bulged inward from a side surface. An extended guide rail is laid, and on this guide rail, a base plate on which a horizontal slide rail extending in the left-right direction is laid on the upper surface is provided so as to be movable back and forth,
A seat whose seat cushion width is wider than the width of the base plate is attached to the lateral slide rail via a seat base plate.

[0005]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a preferred embodiment of the present invention will be described with reference to a body floor surface 20 of a luggage compartment where a tire house 21 is bulged inward from both side surfaces up to the rearmost side of the luggage compartment. The movable left and right rear seats will be described in detail. 1, 1 is a pair of left and right guide rails laid on the body floor surface 20 such that one is disposed inside the tire house 21;
1 is a base plate that moves back and forth via rollers 3, and by moving each base plate 2 back and forth along the guide rails 1 and 1, each sheet 30 above it can be moved back and forth. The basic configuration is the same as that of a conventional vehicle seat of this type.

However, in the present invention, the seat 30 whose seat cushion width is wider than the width of the base plate 2 with the rearward movement of the seat 30 is changed to the tire house 21.
It is possible to move while avoiding the protrusion, which is a feature of the present invention. Specifically, a pair of horizontal slide rails 4, 4 orthogonal to the guide rails 1, 1 are provided on the base plate 2, and the sheet 30 is mounted on the horizontal slide rails 4, 4 on the upper surface. A certain sheet base plate 5 is mounted movably in the lateral direction, and a guide roller 7 is provided on the lower surface of the sheet base plate 5 so as to reach a lower side through the base plate 2. Then, the base plate 2 moves back and forth and the tire house 2
When passing through the side of the base plate 2, the guide plate 6 is guided in contact with an avoidance guide rail 6 disposed in the vicinity thereof, for example, inside the outer lateral slide rail 4, and moves back and forth as the base plate 2 moves back and forth. The seat base plate 5 is automatically moved right and left along the horizontal slide rails 4 and
To avoid the bulge.

Reference numeral 8 denotes a horizontal slide guide suspended from the seat base plate 5. The horizontal slide guide 8 is fitted to the horizontal slide rail 4, and the seat base plate 5 is guided by the horizontal slide rail 4. A guide roller which can be moved in the lateral direction, and which comes into contact with the above-described avoidance guide rail 6 when the base base plate 2 which moves back and forth on the seat base plate 5 passes beside the tire house 21. 7
As a result, the seat base plate 5 is guided so as to be moved left and right along the horizontal slide rails 4 and 4 as it moves back and forth. It slides while automatically avoiding the protrusion of the house 21.

A spring 9 is stretched on the seat base plate 5 so that the seat base plate 5 is always urged outward by the spring 9 and guided by the guide rail 6 for avoidance. After the seat base plate 5 guided by the guide rollers 7 in the lateral direction on the inside of the vehicle passes through the guide rails 6 for avoidance, the seat base plate 5 is automatically returned to the outside of the vehicle again. The body floor surface 20 is provided with stoppers 10 for fixing the guide rollers 7 on the frontmost side and the rearmost side of the moving sheet 30, and the sheet placed on the sheet base plate 5 at each position. 30 is configured to prevent lateral blurring.
Further, a hinge mechanism 11 is attached to the front end of the base base plate 2, and a lock mechanism 12 is attached to the rear end. If necessary, the entire rear seat is turned forward to form a flat luggage compartment. It has a structure that can be used. Although the right rear seat has been described above, the left rear seat is provided with a mechanism which is symmetrical to the above.

A conventional slide of this type is constructed such that the rear seat can be freely moved back and forth to an arbitrary position along the guide rails 1 and 1 by releasing the seat slide lock 13. Is the same as that of the type automobile seat, except that the guide rails 1
A pair of horizontal slide rails 4, 4 orthogonal to 1 are provided, and the horizontal slide rails 4, 4
The seat base plate 5 on which the tire housing 21 is mounted is movably mounted in a lateral direction. The guide base 6 is guided by an avoidance guide rail 6 provided corresponding to the protrusion shape of the tire house 21. Since the roller 7 is provided, when the tire house 21 is moved back and forth, the base plate 2 moves straight along the guide rail 1, but the seat base plate 5 has the guide roller 7. By being guided by the avoidance guide rail 6, the vehicle moves while being guided in the lateral direction on the vehicle interior side so as to avoid the protrusion of the tire house 21.

As a result, as shown in FIG. 3, both the left and right rear seats are moved in the lateral direction while avoiding the protrusion of the tire house 21, that is, while sliding toward the center of the car, they slide. After passing through the tire house 21, the vehicle returns to the outside of the vehicle again, and is used at an optimum position on the rearmost side. Further, the seat base plate 5 can automatically return to the outside of the vehicle again after passing through the avoidance guide rail 6 by the action of the spring 9, and further, since the guide roller 7 is fixed by the stopper 10, the seat Of the sheet at the forefront side and the rearmost side can be reliably prevented. It is also possible to use the hinge mechanism 11 to fold the entire rear seat to the front side to form a flat luggage compartment.

[0011]

As is apparent from the above description, the present invention slides the rear seat over a long distance to the rearmost side of the vehicle with a simple structure and without being restricted by the seat shape or the rail locus. While being able to
The operation of sliding the sheet can be performed by an easy procedure, and the sheet folding function is excellent. Therefore, the present invention greatly contributes to industrial development as an automotive seat that has eliminated the conventional problems.
