[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION The present invention provides an excellent design by reliably preventing the shielding cloth for concealing the gap between the sheet and the body from being twisted even when the sheet is moved forward. The present invention relates to a rear seat for an automobile that can secure a surface.

[0002]

2. Description of the Related Art Recently, for the purpose of securing a comfortable posture when sitting down, a slide-movable type in which an angle of a seat back that changes in accordance with the forward and backward movement of the seat cushion is connected to the rear of a seat cushion that can be moved forward and backward. Automotive rear seats are widely used.

However, in this type of conventional rear seat for an automobile, as disclosed in Japanese Utility Model Laid-Open Publication No. Sho 62-129331, a gap between the seat and the body when the seat is moved forward is hidden. Since the shielding member is structured to be fixed to the sheet and the body, there is a problem that the shielding member is twisted or non-uniform tensile force is generated, and the appearance is significantly impaired. In addition, as the amount of movement of the seat increases, the occurrence of twisting becomes more pronounced, which causes a limitation on the amount of movement of the seat, and there is also a problem that it is not possible to design a rear seat for an automobile having a larger amount of movement of the seat. Was.

[0004]

SUMMARY OF THE INVENTION The present invention solves the above-mentioned conventional problems. Even when the seat is moved forward, the shielding cloth for concealing the gap between the seat and the body is twisted or twisted. While preventing uneven tensile force etc. from being generated, it is possible to secure an excellent design surface,
It has been completed for the purpose of providing an automobile rear seat capable of securing a more comfortable and comfortable posture by increasing the amount of movement of the seat.

[0005]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, an automobile rear seat according to the present invention changes the angle at the rear of a seat cushion movable forward and backward in conjunction with the forward and backward movement of the seat cushion. In an automobile rear seat to which a seat back is connected, a U-shaped leaf spring that expands in a fan-like manner by a resilient force along with a forward movement of the seat back is attached to a lower side surface of the seat back. In addition, a bellows-type shielding cloth for concealing a gap is mounted on the expanding surface of the leaf spring.

[0006]

In the present invention constructed as described above, when the seat back is moved forward, the U-shaped leaf spring attached to the lower side surface portion naturally expands fanwise rearward by the elastic force. The bellows-type gap concealing shielding cloth mounted on the expanding surface of the leaf spring is uniformly opened without generating twist or the like, so that the gap between the seat and the body is securely concealed.

[0007]

BRIEF DESCRIPTION OF THE DRAWINGS FIG. In the drawing, reference numeral 1 denotes a seat cushion installed so as to be able to move back and forth on a rail 2, and reference numeral 3 denotes a connection having a link mechanism and the like at a rear portion of the seat cushion 1 so as to change an angle in conjunction with the forward and backward movement of the seat cushion 1. The seat backs are connected by metal fittings, and since these mechanisms are not different from those well-known, description thereof is omitted.

One piece of a rectangular leaf spring 5 which expands in a fan shape by a resilient force is attached to a lower frame 4 on a lower side surface of the seat back 3 by bolts 6. The other piece is configured so that it can be freely expanded by elastic force without being fixed to the body or the like.
Further, a shielding cloth 7 for concealing a gap made of the same fabric cloth or the like as covering the sheet surface is mounted on the expanded surface of the leaf spring 5. As shown in FIG. 3, the shielding cloth 7 has a length sufficient to cover the expanded surface of the leaf spring 5 when the leaf spring 5 expands in a fan shape, and also ensures that both pieces of the leaf spring 5 are in close contact with each other. When closed, the bellows type is configured so as to follow it and close smoothly and formally.

The mounting hole 8 provided in the leaf spring 5 is
It is preferable to form an adjustable long hole so that the engagement with the lower frame 4 can be performed more accurately. Further, as shown in FIG. 4, for example, a rotatable hinge 9 is provided at the tip of one piece of the leaf spring 5 attached to the lower frame 4, and the hinge 9 is engaged with the rear end of the seat cushion 1, so that The spring 5 can also be made to reliably follow the forward / backward movement of the seat cushion 1. In this case, the gap between the seat cushion 1 and the seat back 3 is also concealed securely, and the appearance is further improved. It will be good.

[0010] In the structure configured as described above,
If the seat cushion 3 is installed in the vehicle body in a conventional manner and the relationship between the seat back 3 and the seat cushion 1 is desired to be a comfortable posture, the seat cushion 1 can be moved forward to change the inclination angle with the seat back 3. This is the same as the conventional rear seat for an automobile, but in the present invention, the lower frame of the V-shaped leaf spring 5 attached to the lower side surface portion as the seat back 3 moves forward. The piece that is not engaged with 4 is spontaneously expanded rearward in a fan-like manner by the resilient force, and accordingly, a bellows-type concealing shielding cloth 7 attached to the expanded surface of the leaf spring 5 is attached.
Is uniformly opened without causing twisting or the like, and the gap between the seat and the body is securely hidden. Further, since the shielding cloth 7 is uniformly expanded by the U-shaped leaf spring 5 without causing twist or the like, the seat cushion 1 can be arbitrarily adjusted by adjusting the expansion angle of the leaf spring 5. Since the moving amount can be changed, a larger moving amount can be secured as compared with the related art. On the other hand, when the relationship between the seat back 3 and the seat cushion 1 is set at the normal position, the expanding surface of the leaf spring 5 is compressed and closed, and the shielding cloth 7 attached to the expanding surface also has a bending line. Of course, it is in a state of being compressed compactly along the line, and is not stored in the rear side of the body and does not impair the appearance.

[0011]

[Effect of the Invention] As is clear from the above description, in the present invention, even when the sheet is moved forward, the shielding cloth for concealing the gap between the sheet and the body is subject to twisting and uneven tensile force. It is possible to reliably prevent the occurrence of such a problem, to secure an excellent design surface, and to secure a more comfortable comfortable posture by increasing the amount of movement of the seat. It also has the advantage that it can be easily attached with a simple structure and cost can be greatly reduced. Therefore, the present invention has a very high practical value as a rear seat for an automobile which has solved the conventional problems.
