Description

  The present invention relates to a vehicle seat having a reversible skin material (a skin material that can be used on a seating side by selecting one of a first skin part and a second skin part).

As this type of vehicle seat, a vehicle seat disclosed in Patent Document 1 is known. This vehicle seat has a cushion material forming an outer shape of the seat and a skin material capable of covering the cushion material.
A part of the skin material (for example, the skin material part covering the center of the seat back) has the first skin part and the second skin part in a layered state, and is detachable from the cushion material.
The first skin portion is, for example, a fabric tension, and the second skin portion is a moquette tension (pile fabric). And in a well-known technique, either one of both skin parts is selected and it can be attached to a cushioning material in the state which turned the other side different from one to the cushioning material side (back side).

Japanese Utility Model Publication No. 02-47939

By the way, in a well-known technique, both a 1st skin part and a 2nd skin part can be used for a seating side. Since the outer dimensions of the first skin portion and the second skin portion are determined on the basis of the state when the first skin portion and the second skin portion are arranged on the seating side, there may be some problems in seat performance.
For example, the first skin part is used on the seating side and the second skin part is used on the back side. At this time, the first skin portion has an appropriate surface shape, but the second skin portion on the back side is slightly too slightly (so-called circumferential difference occurs). More specifically, when the first skin part and the second skin part are installed on the gently recessed surface of the seat back or the seat cushion, or both skin parts are in a direction different from the tension direction in the hanging groove. A difference in circumference occurs when it is suspended and fixed. As a result, in the configuration of the known technique, wrinkles or twists may be generated in the second skin portion, and partial unevenness may be generated in the first skin portion (it was inferior in seating property).
The present invention has been devised in view of the above points, and the problem to be solved by the present invention is to use the first skin portion and the second skin portion with good seating properties.

As means for solving the above-mentioned problems, the vehicle seat of the first invention has a seat constituent member such as a seat cushion and a seat back. And a sheet | seat structural member has the skin material which can coat | cover the cushion material which makes a seat external shape, and a cushion material.
In this invention, the above-mentioned skin material has a 1st skin part and a 2nd skin part in a multilayered state. Then, either one of the two skin portions can be selected and directed to the seating side of the seat, and the other can be attached to the cushioning material with the other side facing the cushioning material side.
In this type of seat configuration, it is desirable that the first skin portion and the second skin portion can be used with good seating properties. Therefore, in the present invention, since the second skin portion described above is a face material that is more easily expanded and contracted than the first skin portion, even if wrinkles or the like (projections) occur in the first skin portion, the second skin portion The same part can be absorbed as much as possible by expanding and contracting.

The vehicle seat of the second invention has a seat constituent member such as a seat cushion and a seat back. And a sheet | seat structural member has the skin material which can coat | cover the cushion material which makes a seat external shape, and a cushion material.
In this invention, the above-mentioned skin material has a 1st skin part and a 2nd skin part in a multilayered state. Then, either one of the two skin portions can be selected and directed to the seating side of the seat, and the other can be attached to the cushioning material with the other side facing the cushioning material side.
Therefore, in the present invention, both the first skin portion and the second skin portion described above are mesh-like face materials, and each skin portion can be expanded and contracted according to the arrangement state (a configuration in which a difference in circumferential length is less likely to occur). )

  According to the first aspect of the present invention, the first skin portion and the second skin portion can be used with good seating properties. Moreover, according to the 2nd invention, a 1st skin part and a 2nd skin part can be used more reliably with sufficient seating property.

It is a perspective view of a vehicle seat. It is a longitudinal cross-sectional view of a part of the seat back. 4 is a longitudinal sectional view of a part of a seat back of Example 2. FIG.

Hereinafter, embodiments for carrying out the present invention will be described with reference to FIGS. In each of the drawings, a reference symbol F is attached to the front of the vehicle seat, a reference symbol B is attached to the rear of the vehicle seat, a reference symbol UP is provided above the vehicle seat, and a reference symbol DW is provided below the vehicle seat.
The vehicle seat 2 in FIG. 1 includes seat constituent members (a seat cushion 4, a seat back 6, and a headrest 8). Each of these seat constituent members has a cushion material (4P, 6P, 8P) and a skin material (4S, 6S, 8S).

<Example 1>
The seat back 6 has a cushion material 6P and a skin material 6S (see FIG. 1).
In the present embodiment, a part of the skin material of the seat back 6 has two face materials (a first skin part 61 and a second skin part 62) (details will be described later). And it can attach to cushion material 6P directly or indirectly in the state where either one of both skin parts was chosen and arranged on the seating side of the seat.
In this type of seat configuration, it is desirable that the first skin portion 61 and the second skin portion 62 can be used with good seating properties. Therefore, in this embodiment, the first skin portion 61 and the second skin portion 62 are used with good seating properties by the configuration described later. Hereinafter, each configuration will be described in detail.

(Cushion material)
The cushion material 6P is a member forming a seat outer shape, and includes a seating portion 6a, a side support portion 6b, and a part of an engagement member 30 described later (see FIG. 2). The seating portion 6a is a recessed portion serving as a seating portion for the occupant and can be formed in the center of the seat. Moreover, the side support part 6b is a convex part of the both sides of the seating part 6a, and can support the side part of a passenger | crew (illustration omitted).
The material of the cushion material 6P is not particularly limited, but is typically a resin such as polyurethane foam.

(Skin material)
The skin material 6S includes a first skin portion 61, a second skin portion 62, a basic skin portion 63, and other portions of the engagement member 30 described later (see FIG. 2).
The basic skin portion 63 is a face material that covers the entire cushion material 6P (such as the seating portion 6a and the side support portion 6b). The type of the basic skin portion 63 (face material) is not particularly limited, and examples thereof include fabric (woven fabric, knitted fabric, non-woven fabric), leather (natural leather, synthetic leather), and composite materials thereof. A supplementary member (not shown) such as a pad material or a back base fabric can be disposed on the back side of the basic skin portion 63. As the pad material, an elastic body that is more flexible than the cushion material 6P can be used, and a nonwoven fabric can be used as the back base fabric.
Here, the fabric can typically be composed of natural fibers or synthetic fibers. Examples of natural fibers include animal fibers such as wool and silk, and plant fibers such as hemp and cotton. Examples of synthetic fibers include polyester fibers, polyamide fibers, polyvinyl alcohol fibers, cellulose fibers, and mixed yarns thereof.
In this embodiment, the basic skin portion 63 covers the seating portion 6a and the side support portion 6b. Note that the end portion of the basic skin 63 can be locked to a frame member (member forming a seat skeleton) (not shown) by another locking member (not shown).

(First skin)
The first skin portion 61 is a face material that can cover the center of the seating portion 6a (see FIG. 2). The type of the first skin portion 61 (face material) may be the same as or different from the basic skin portion 63. Examples of the typical first skin portion 61 include natural fiber or synthetic fiber fabric (woven fabric, knitted fabric, non-woven fabric), leather (natural leather, synthetic leather), and composite materials thereof. On the back side of the first skin portion 61, a pad material or a back base fabric can be disposed.
The first skin portion 61 of the present embodiment is a substantially rectangular face material, and its outer dimension is determined based on the state when it is disposed on the seating side. For this reason, when using the 1st skin part 61 as a seating side, it becomes an appropriate surface shape (shape along the external shape of a cushion material, and a shape which does not produce as much as wrinkles). On the other hand, when it is used on the back side different from the seating side, the first skin portion 61 is slightly too slightly (peripheral length difference occurs).

(Second skin)
The 2nd skin part 62 is a surface material which can coat | cover the center of the seating part 6a, and can be layered on the 1st skin part 61 (refer FIG. 2).
The second skin portion 62 is a face material that expands and contracts more easily than the first skin portion 61 described above. Examples of the second skin portion 62 include a knitted fabric such as a jersey and a net body (a member in which fibers are woven in a mesh shape, a mesh-like face material). The net body may entangle fibers (natural fibers or synthetic fibers) two-dimensionally or entangle fibers three-dimensionally. In addition, the net body (3D net body, space raschel) entangled three-dimensionally has excellent air permeability because there is a gap inside. Therefore, the second skin portion 62 of the 3D net body can maintain a good seating property without causing discomfort such as stuffiness in summer.
The second skin portion 62 of the present embodiment is a substantially rectangular face material, may have the same outer dimensions as the first skin portion 61, and may define an outer dimension slightly smaller than the first skin portion 61. it can. And when using the 2nd skin part 62 as a seating side, the 2nd skin part 62 becomes a suitable surface shape by extending | stretching a little as it is. Further, when used on the back side different from the seating side, the second skin portion 62 is reduced or becomes an appropriate surface shape with the external dimensions as it is.

In the present embodiment, the gap portion CL is formed between the first skin portion 61 and the second skin portion 62, but other members may be disposed.
Although the kind of other member is not specifically limited, A pad material, a heat insulating material, a cold insulating material, a heat insulating material, and various sensors can be illustrated.

(Engagement member)
In the present embodiment, the first skin portion 61 and the second skin portion 62 can be attached to the basic skin portion 63 (indirectly to the cushion material 6P) by the engagement member 30 having the slide fastener structure. And the engaging member 30 has a pair of fastener pieces 32 and 34 (refer Fig.2 (a)).
For example, one fastener piece 32 is attached to both ends of the first skin portion 61 and the second skin portion 62. At this time, one fastener piece 32 is sandwiched between both end portions while facing the end portion (inwardly folded shape) of the first skin portion 61 and the end portion (inwardly folded shape) of the second skin portion 62. Sewing.
Further, the other fastener piece 34 is attached to the basic skin portion 63 so as to face the one fastener piece 32.

[Installation work of skin material]
Referring to FIG. 2, after covering cushion material 6 </ b> P with basic skin portion 63, first skin portion 61 and second skin portion 62 are attached.
For example, one fastener piece 32 is engaged with the other fastener piece 34 while the second skin portion 62 faces the seating side. The first skin portion 61 and the second skin portion 62 are attached to the cushion material 6P via the basic skin portion 63 (indirectly). At this time, the first skin portion 61 is arranged on the back surface side different from the seating side in a slightly slightly undisturbed state (in a state where a circumferential length difference occurs). For this reason, some wrinkles or the like are generated in the first skin portion 61, but in this embodiment, wrinkles or the like (protrusion portion W) of the first skin portion 61 can be absorbed by the extension of the second skin portion 62. Therefore, the surface of the skin material 6S is difficult to be uneven, and good seating property can be maintained as much as possible.
Further, one fastener piece 32 is engaged with the other fastener piece 34 while the first skin portion 61 faces the seating side. Thus, when using the 1st skin part 61 as a seating side, it becomes an appropriate surface shape. Further, the second skin portion 62 on the back surface side is reduced or becomes an appropriate surface shape with the external dimensions as it is.

  As described above, according to the present embodiment, since the second skin portion 62 described above is a face material that is more easily expanded and contracted than the first skin portion 61, the first skin portion 61 has wrinkles or the like (protrusion portion W). Even if this occurs, the projecting portion W can be absorbed as much as possible by the expansion and contraction of the second skin portion 62. For this reason, according to the present Example, the 1st skin part 61 and the 2nd skin part 62 can be used with sufficient seating property.

<Example 2>
Since the vehicle seat of the present embodiment has substantially the same basic configuration as the vehicle seat 2 of the first embodiment, the common structure is denoted by the corresponding reference numerals and detailed description thereof is omitted.
In the present embodiment, both the first skin portion 61 and the second skin portion 62 described above are mesh face materials (see FIG. 3). For this reason, when using the 1st skin part 61 as a seating side, the 1st skin part 61 becomes an appropriate surface shape by the external dimension as it is, or expand | extends. Further, when the first skin portion 61 is used on the back side different from the seating side, the first skin portion 61 is reduced or becomes an appropriate surface shape with the external dimensions as it is.
Similarly, when the second skin portion 62 is used as the seating side, the second skin portion 62 has the same outer dimensions or expands to have an appropriate surface shape. Further, when the second skin portion 62 is used on the back surface side different from the seating side, the second skin portion 62 is reduced or becomes an appropriate surface shape with the external dimensions as it is.

Thus, in the present Example, both the 1st skin part 61 and the 2nd skin part 62 were made to be able to expand-contract according to the arrangement | positioning condition (it was set as the structure which does not produce a circumference difference easily). The first skin portion 61 and the second skin portion 62 (mesh-like face material) have a space inside, and are more stretchable (especially shrinkability) than other face materials, so depending on the arrangement situation Can be expanded and contracted more appropriately.
For this reason, according to the present Example, the 1st skin part 61 and the 2nd skin part 62 can be used more reliably with sufficient seating property.

The vehicle seat of the present embodiment is not limited to the above-described embodiment, and can take other various embodiments.
(1) In the present embodiment, the example in which the part of the skin material of the seat back 6 has the first skin part 61 and the second skin part 62 has been described. Unlike this, the entire skin portion of the seat back 6 may have a first skin portion 61 and a second skin portion 62.
(2) In the present embodiment, the engagement member 30 having the slide fastener structure is illustrated, but the configuration of the engagement member is not limited. For example, various members such as a hook-and-loop fastener, a button, and a hog ring member (a ring member and a wire that can be inserted into the ring member) can be used as the engaging member.
(3) In the present embodiment, the seat back 6 has been described as an example of a seat constituent member. The configuration of the present embodiment can be applied to various seat components such as the seat cushion 4 and the headrest.
(4) Moreover, in this embodiment, the structure of the vehicle seat 2 was demonstrated exclusively. The configuration of the present embodiment can be applied to various seats such as a home seat.
(5) In the present embodiment, the example in which the first skin portion 61 and the second skin portion 62 are attached to the cushion material 6P via the basic skin portion 63 (indirectly) has been described. Unlike this, the first skin portion 61 and the second skin portion 62 can also be directly attached to the cushion material 6P. For example, when the first skin portion 61 and the second skin portion 62 are attached to the cushion material 6P via the basic skin portion 63, the other fastener piece 34 is provided on the cushion material 6P, and the same is obtained from the hole formed in the basic skin portion 63. It is good also as a structure which makes the fastener piece 34 protrude and it engages with one fastener piece 32. FIG.
