Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a seat with a backrest, particularly a large-sized seat suitable for long-distance touring and the like, which has different seating positions of a driver and a passenger. About.

[Prior Art] Conventionally, a seat with a backrest has a cushioning material 42 on a bottom plate 41 as shown in FIG. 4A, for example.
The cushioning material 42 is formed by using a skin member 46 formed in a desired shape by sandwiching the wadding material 43 between a skin 45 and a backing material 44. When the backrest Sb is formed between the front seat Sf and the rear seat Fr, the bottom plate 41 is formed integrally with the bottom plate 41 in order to form a supporting portion of the backrest Sb from the problem of the number of parts. The extending portion 41a extending upward was formed on the backrest Sb.

[Problem to be solved by the invention] In the double sheet S as shown in FIG. 4A,
As shown in FIG. 4B, when seated, the skin member 46 and the cushion member 42 are simultaneously compressed in accordance with the load, and the state is concentrated on a predetermined portion of the seat S. For this reason, there is a problem that the feeling of fatigue is increased when sitting for a long time.

In addition, the support portion of the backrest Sb is
This bottom plate 4 is composed by 41a
In the case of 1, the load of the backrest was received, which caused a feeling of strangeness and a lack of softness.

An object of the present invention is to provide a seat with less fatigue when seated for a long time.

Another object of the present invention is to provide a seat with a backrest having improved riding comfort.

Means for Solving the Problems The present invention has been made to solve the above problems, and a seat with a backrest according to the present invention has a backrest in which the positions of the front and rear seats are different. A seat, on which a main cushion material having a rising portion between the front seat and the rear seat is placed on a main bottom plate, and the front seat and the rear seat are covered with a skin material; A sub-bottom plate is placed on a main cushion material placed on a main bottom plate, and a sub-cushion material is placed on the sub-bottom plate and covered with the skin material. The bottom plate is provided with a standing portion along a rising portion of the main cushion material.

The sub-bottom plate is preferably formed to be softer than the main bottom plate. Further, it is preferable that the main cushion material is formed harder than the sub cushion material.

[Operation] As described above, the seat with a backrest according to the present invention has a sub-bottom plate placed on a main cushion material placed on a main bottom plate, and a sub-cushion placed on the sub-bottom plate. The sub-bottom plate is provided with a standing portion along the rising portion of the main cushion material, so that the load applied to the sub-cushion material by sitting is It can be received by the bottom plate and applied to the main cushion material with a wide surface pressure, and the load characteristics of the main cushion material can be used effectively. Further, in the backrest portion, the sub-bottom plate is slightly flexible and can be moved, so that elasticity can be given according to the movement of the body, and an appropriate spring feeling is given.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
The members, arrangements, and the like described below do not limit the present invention, but can be variously modified within the scope of the present invention.

1A to 1E show a first embodiment of the present invention, in which a seat S is a large one suitable for long-distance boarding, and as shown in FIG. 1A, a front seat Sr and a rear seat Sr And a backrest Sb utilizing the step is formed. As shown in FIGS. 1B and 1C, the seat S is provided with a hard main cushioning material 11 placed on a conventionally used resin main bottom plate 10 and the main cushioning material 11 placed thereon. A sub-bottom plate 12 that is softer than the bottom plate 10 is placed, and a sub-cushion material 13 that is softer than the main cushion material 11 is placed thereon, and a skin 14
It is what was covered with. As shown in FIG. 1B, the main cushion material 11 has a rising portion 11 between the front seat Sf and the rear seat Sr.
a is formed. Similarly, as shown in FIG. 1B, the sub-bottom plate has a standing portion 12a formed along the rising portion of the main cushion material.

Further, as shown in FIG. 1D, the seat side portions (the left and right sides in FIG. 1C) of the sub-bottom plate 12 are formed to be curved inward so as to prevent a feeling of strangeness when seated. Reference numerals 15 and 16 are mounting stays.

As shown in FIG. 1D, the sheet S having the above configuration
When the seat is seated and a load is applied, the load is received by the sub-bottom plate 12 on a wider surface, and the surface pressure can be substantially uniformly applied to the main cushion material 11 in a spread state. Characteristics can be fully exhibited. Regarding the load of the backrest portion, as shown in FIG. 1E, the upright portion 12a of the sub-bottom plate 12 is slightly flexible and can move in the direction of the arrow X to give elasticity in accordance with the movement of the body. You can get a moderate spring feeling,
The sitting comfort can be improved.

FIG. 2 shows a second embodiment of the present invention, in which the same members and materials as those in the first embodiment are given the same reference numerals, and their explanation is omitted.

In the present embodiment, the sub cushion material 13 is sandwiched between the sub bottom plate 12 and the skin material 14, and the skin material 14 and the sub bottom plate 12 are welded by the weld processing part 15. With the configuration as in the present example, a pattern-like pattern can be added to the surface, and the merchantability can be improved.

FIGS. 3A and 3B show a third embodiment of the present invention. In this embodiment, the same members and the like as those in the first embodiment are denoted by the same reference numerals, and description thereof will be omitted.

In this example, both sides 30a, 30a of the sub-bottom plate 30 are formed by projecting like side supports,
Even if the external shape is complicated, the external shape can be maintained.

[Effect of the Invention] Since the present invention is configured as described above, the load received by the sub-cushion material can be diffused by the sub-bottom plate so that the surface pressure does not concentrate. The characteristics can be effectively used, and the riding comfort can be improved. Also, since the load of the backrest portion is received by the sub-bottom plate, an appropriate spring feeling can be obtained and the riding comfort can be improved.
