Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a vehicle seat, and more particularly to a vehicle seat in which a side support portion or the like is provided with a boundary between the seat main portion and the seat main portion.

[Prior Art] Vehicle seats are sometimes individually designed to suit the body shape of the user, but usually the seats are designed based on the type of vehicle in which they are equipped, and are designed to suit the user's needs. It is designed with a standard body shape in mind.

In recent years, in addition to adjustment mechanisms attached to seats such as reclining and lifter mechanisms, improvements have also been made to the comfort of seats, such as side support,
Seats that incorporate retention and adjustment mechanisms for the seat itself, such as thigh supports, have been put into practical use.

This type of holding adjustment mechanism moves support members such as auxiliary frames installed inside the side support part and thigh support part by a drive means consisting of cams, links, air, etc., and each support part is moved relative to the seat main part. The amount of protrusion and the angle of the protrusion can be changed to suit the body shape of the person sitting.

[Problems to be solved by the invention] By the way, conventional seat retention and adjustment mechanisms can adapt the seat shape based on the standard seater body shape to a certain degree to a specific seater body shape, and have a certain degree of comfortable retention. contributes to

However, in reality, the shape of the seat main part is fixed, so even if you adjust the protrusion amount and protrusion angle of each support part, it is only a relative change to the seat main part, and the standard It has been found that it is not very useful for sitters whose physiques are significantly different.

This means, for example, that a seater with a large physique may have the side support portions expanded, while a seater with a small physique may have the side support portions contracted. However, in either case, the height and width of the seat main portion are not changed, making it difficult to fit the seat to the body physique.

In such cases, the current situation is that auxiliary pads such as cushions are applied to the seat main part, side support parts, etc., without relying on the built-in seat holding and adjusting mechanism.

Recently, there has been an increase in the number of sheet forming methods in which a skin material and a pad, or a skin material, a pad, and a frame are integrally molded into a sheet shape, thereby drastically reducing the number of man-hours such as assembly. In principle, the above-mentioned seat holding and adjusting mechanism cannot be used with this integrally molded skin sheet.

Therefore, as a result of various studies based on this background, the present applicant was able to confirm that the fitability could be greatly improved by making technical improvements to the conventional auxiliary pad, and thus came up with the present invention. .

The object of the present invention is to provide a vehicle seat that can be implemented simply and at low cost, and that can improve the fit of the occupant even if it is a standard seat.

[Means for Solving the Problems] In order to achieve the above object, the present invention provides a vehicle seat including a flexible auxiliary pad superimposed on the seat main portion, the auxiliary pad being superimposed on the seat main portion. One end of the auxiliary pad is joined to the boundary between the side support part and the thigh support part, and the joint part is used as a hinge to overlap the side support part or the thigh support part along the curved surface. Features.

[Function] According to the present invention configured as described above, the joint part of the auxiliary pad plays the role of a hinge, so the auxiliary pad can be freely changed to the seat main part, the side support part, or the thigh support part via the hinge. I can do it.

In this case, since the auxiliary pads are flexible, they are integrally stacked not only on the seat main portion but also along the curved shape of the thigh support portion and the like, and function as different sheet holding surface shapes. As a result, a sufficient holding function can be obtained even for a seater whose physique is significantly different from that of a standard seat.

[Example] Hereinafter, an example of the present invention will be described based on the drawings.

FIG. 1 is an external perspective view of a vehicle seat to which the present invention is applied, and FIG. 2 is a sectional view taken along the line -- of the seat cushion in the same figure.

The vehicle seat 1 shown in the figure consists of a seat cushion 2, a seat back 3, and a headrest 4 similar to the conventional ones, and a first auxiliary pad 5 and a third auxiliary pad 14 provided on the seat cushion 2,
A second auxiliary pad 9 provided on the seat back 3 is provided.

The seat cushion 2 has a seat main part 2a corresponding to the buttocks, side supports 2b on both sides of the seat main part 2a that are raised one step, and a thigh support part 2c located in front of the seat main part 2a. They are integrated and separated by boundaries 6a and 6b.

In the seat back 3, a seat main portion 3a corresponding to the back, side support portions 3b located on both sides of the seat main portion, and a portion 3c located at the lower part of the headrest 4 form boundaries 10a, 1 in appearance.
They are integrated in a state where they are divided by 0b.

The first auxiliary pad 5 is made up of a plurality of sheets superimposed on the upper surface of the seat main portion 2a of the seat cushion 2, as shown in FIG. That is, the first auxiliary pad 5 is composed of four unit pads 5a, 5b, 5c, and 5d, and the third auxiliary pad 14 is composed of one unit pad.

Each pad 5a, 5b, 5c, 5d or third
The auxiliary pad 14 is made of, for example, urethane foam covered with a skin material, and has a mounting piece on one side.

For example, the mounting piece may be formed by extending a part of the skin material covering each of the pads as in the embodiment, or
Alternatively, it can be constructed from a separate cloth material or the like.
Further, the length of each of the mounting pieces is slightly different depending on the mounting condition.

And padded 5 attached to the right border
The pads 5c and 5d attached to the left side border are located at the border 6a between the seat main part 2a and the side support part 2b, and are sewn with the mounting piece sandwiched between them when the skin material 7 is sewn. , are integrated at the joint 8.

In addition, the auxiliary pad 14 includes the side support portion 2c and the seat main portion 2c as shown in FIGS. 5 and 6.
At the boundary 6b of ``a'', when sewing the skin material 7, the mounting piece is sewn with the attachment piece sandwiched therebetween, and is integrated at the joint 15.

Therefore, an arbitrary number of pads 5a, 5b, 5c, and 5d are stacked on top of each other along the curved shape of the side support portion 2b, as shown in FIGS. 3 to 4, using the joint portion 8 as a hinge.

On the other hand, the seat back part 3 is provided with a second auxiliary pad 9 which has a functional structure.

The second auxiliary pad 9 is composed of two pads 9a and 9b.
a and 9b are attached via the attachment piece.

Therefore, the pads 9a and 9b are overlapped along the curved surface of the side support portion 3b using the joint portion (not shown) that is integrated when the skin material 11 is sewn as a hinge. Although not shown in the drawings, the pads 9a and 9b are provided with simple locking members such as hook and loop fasteners on the free end sides to prevent them from shifting at each use position.

Examples of the use of the present invention will be described above with reference to FIGS. 2 to 4, which show the first auxiliary pad 5.

FIG. 2 shows a state in which all of the pads 5a, 5b, 5c, and 5d are alternately overlapped on the upper surface of the seat main portion 2a.

Figure 3 shows the pads 5b and 5d in the seat main section 2.
This is a state in which the pads 5a and 5c are superimposed on the upper surface of the side support portion 2b along the curved shape of the both side support portions 2b.

FIG. 4 shows a state in which all of the pads 5a, 5b, 5c, and 5d are sequentially stacked on the upper surface of both side support portions 2b.

Here, for example, it is assumed that the state shown in FIG. 3 forms a sheet holding shape that is almost the same as that of a conventional standard sheet. Between the side support parts that intersect with the top surface of pad 5b (actually between pad 5a and pad 5c),
In other words, the seat main width is m.

However, in FIG. 4, since the pads 5b and 5d are added, the sheet main width becomes n dimension smaller than m. Further, the seat holding shape is a bucket type in which the seat main portion 2a is lowered one step.

In this state, by overlapping the pad 14 on the seat main portion 2a as shown in FIG. 6, the seat can be fitted to a seater who is smaller than a standard physique.

Further, in FIG. 2, since pads 5a and 5c are further added to the seat main portion 2a, the seat main width becomes larger than m. In this case, the fit is better for a person who is larger than the standard size.

In this way, by using the auxiliary pads 5 and 14 properly, the fit of the seater can be finely adjusted.

Furthermore, since the auxiliary pads 5, 9, and 14 are assumed in advance at the design stage of the seat 1,
By configuring the auxiliary pads 5, 9, and 14 with different thicknesses, it is possible to easily improve the fit of the seater even with a standard seat. in this case,
The auxiliary pads 5, 9, and 14 allow the sheet 1 to be used as a sheet holding shape different from that of the sheet itself.

Further, the structure of the auxiliary pads 5, 9, and 14 may be changed, for example, by changing the thickness, pad hardness, etc., so that the occupant can experience various seat retention properties even though the seat 1 is the same.

Note that, in principle, seat retention adjustment mechanisms such as movable thigh supports cannot be used with integrally molded skin seats, but by applying the auxiliary pads 5, 9, and 14 of the present invention, it is possible to satisfy the fit of the seater to a certain extent. This makes it extremely convenient.

In the above, the present invention is not limited to the configuration of the auxiliary pads 5, 9, and 14, and the material, shape, number, etc. of the pads can be arbitrarily set in relation to the sheet 1. It is.

[Effects of the invention] As is clear from the above examples, the vehicle seat according to the invention achieves the following effects by using the auxiliary pad.
Although the same seat is used, it is possible to simultaneously satisfy the fit characteristics of occupants with different physiques.

In this case, by configuring the auxiliary pad with a plurality of pieces as in the embodiment, it can be fitted to different physiques. As a result, the present invention can easily and inexpensively improve the fit of the occupant even with a standard seat.
