Description

  The present invention relates to a vehicle seat having a skin material.

As this type of vehicle seat, a vehicle seat including a seat cushion and a seat back is known (see Patent Document 1). In this known technique, the seat back is held upside down with respect to the seat cushion via the reclining mechanism, and the lower portion of the seat cushion and the rear portion of the seat back are in contact with each other.
In the vehicle seat of the known technology, both the seat cushion and the seat back are covered with a leather skin material, and has a good design (for example, a high-quality texture).

Japanese Patent Laid-Open No. 2001-70084

However, in the known technology, an abnormal noise due to the contact between the seat cushion and the seat back may occur during the raising / lowering operation of the seat back. That is, when the seat cushion and the seat back skin material (leather) are brought into contact with each other and moved relative to each other during the raising / lowering operation, a rubbing sound due to friction (an abnormal noise such as “Gyu”) may occur.
However, the use of a fabric skin material can reduce the occurrence of abnormal noise, but the fabric skin material does not necessarily have a good design.
The present invention has been devised in view of the above points, and a problem to be solved by the present invention is to prevent or reduce the occurrence of abnormal noise in the sheet while maintaining the design of the sheet as much as possible.

As means for solving the above-mentioned problems, in the vehicle seat of the first invention, at least a part of the skin material is in contact with another part different from the part or another member different from the vehicle seat and It is a configuration that moves.
And in the said structure, there exists a possibility that an abnormal noise may generate | occur | produce by the said one part skin material rubbing at the time of the said relative movement.

Therefore, in the present invention, the part of the skin material is constituted by a horizontal satin fabric (a fabric excellent in design and seating properties). Then, weft treatment or fluffing treatment was performed on the weft yarn of the weft satin fabric, and it was arranged perpendicular to the friction direction. Thus, by making the weft yarn of the weft satin fabric (the weft raised from the surface of the structure) contact the other portion or the other member, it is possible to prevent or reduce the generation of noise due to the friction of the skin material.
That is, in this invention, it has a seat cushion and the seat back hold | maintained so that raising / lowering was possible with respect to the seat cushion. And by performing the raising / lowering operation | movement of a seat back, it is the structure which the 1st contact part of a seat back contacts the 2nd contact part of a seat cushion, and moves relatively.
Therefore, in the present invention, when the seat cushion and the seat back are covered with the skin material made of leather, at least one skin material portion of the first contact portion and the second contact portion is made of a horizontal satin fabric. Then, the weft yarn of the weft satin fabric is arranged perpendicular to the friction direction of one skin material portion during the up-and-down operation, thereby preventing or reducing the generation of noise due to the friction of the skin material.

  A skin material for a vehicle seat according to a second aspect of the invention is the vehicle seat according to the first aspect of the invention, in which the horizontal satin fabric is an eight-point satin fabric. Since this 8-sheet satin fabric has excellent design properties (appearance in which satin lines do not appear as much as possible), the design properties of the sheet can be improved.

A skin material for a vehicle seat according to a third aspect of the invention is the vehicle seat according to either the first aspect or the second aspect of the invention, wherein the horizontal weave fabric is embossed to form an uneven shape (preferably leather-like unevenness). State). In this way, by making the surface of the weft satin fabric uneven, the fabric has a texture that approximates (or is comparable to) leather.

According to the first aspect of the present invention, according to the first aspect, it is possible to prevent or reduce the occurrence of abnormal noise while improving the design of the sheet. Moreover, according to the 2nd invention, the designability of a sheet | seat can be improved further. According to the third invention, the texture of the skin material can be further improved.

<Example 1>
The vehicle seat 2 in FIG. 1 includes a seat cushion 4, a seat back 6, and a headrest 8, and these members are covered with a skin material (4S, 6S, 8S). The seat back 6 is held by the reclining mechanism R so as to be able to rise and fall, and the rear portion of the seat cushion 4 and the bottom of the seat back 6 are in contact with each other.
In this embodiment, when the seat back 6 is raised and lowered, the bottom portion of the seat back 6 (first contact portion 11) and the rear portion of the seat cushion 4 (second contact portion 12) are brought into contact with each other and relatively moved. In this type of configuration, it is preferable to suppress the generation of abnormal noise (such as rubbing noise) due to friction between the skin materials 4S and 6S as much as possible.
Therefore, in this embodiment, the generation of abnormal noise on the sheet is prevented or reduced by the skin material configuration described later. Hereinafter, each configuration will be described in detail.

[Skin material]
In the present embodiment, the skin material portion of the first contact portion 11 (the seat back 6 bottom portion) is configured by a horizontal satin fabric FS described later. Further, the upper side of the skin material 6S (the skin material portion of the portion excluding the first contact portion 11) and the skin material 4S of the seat cushion 4 are constituted by leather LS.
Various leathers such as natural leather and synthetic leather can be used as the leather LS. Examples of natural leather include animal-based natural leather such as cow leather, horse leather, pig leather, deer leather, sheep leather, goat leather, and kangaroo leather. Especially, since cowhide is excellent in texture, it can be suitably used as the leather LS of this embodiment.

[Horizontal woven fabric]
The weft satin fabric FS is a fabric in which weft yarn appears more on the surface of the fabric than the warp yarn (the weft floats from the fabric surface).
This horizontal satin fabric FS is a fabric in which the warp yarn and the weft yarn are N (N ≧ 5) and have a complete structure. For example, a five-sheet satin woven fabric is a fabric that has a complete structure with five warp yarns and a weft yarn each. An eight-sheet satin fabric is a woven fabric that has a complete structure with eight each. Each of the 12 pieces is a woven fabric that forms a complete structure.

The horizontal satin woven fabric FS is loosely entangled with the weft yarn and the warp yarn, so that it is easy to loosen and has a soft hand. For this reason, even if the texture of the horizontal satin fabric FS is slightly thicker, the backing at the time of full back is hardly noticeable due to its flexibility.
Further, the weft fabric FS is smooth and glossy because many weft threads appear on the fabric surface (sitting surface). For this reason, the horizontal satin fabric FS becomes a skin material with excellent quality (a skin material with a good finish).
Among these, the 8 satin woven fabric (described later) is particularly excellent in design, and can be suitably used as a skin material for vehicle seats. In addition, the 5 sheet satin woven fabric tends to be more noticeable than the 8 sheet satin weave. Further, the 12-sheet satin woven fabric has more weft than the 8-sheet satin fabric, so that the satin line tends to be conspicuous during embossing described later.

[Weaving of horizontal weave fabric]
In the present embodiment, weaving of a horizontal satin fabric will be described with reference to 8 satin fabrics as appropriate (see FIGS. 2 to 4).
In the weaving of eight satin fabrics, eight warp yarns (21a to 21h) are arranged in parallel, and then a plurality of weft yarns (20a to 20h) are sequentially crossed based on an organization chart described later. For example, warp yarns (21a to 21h) are stretched in parallel between a pair of horizontal bars (beams). Then, each warp yarn is pulled up by eight ridges to form a gap in which the weft yarn can be driven.
Then, the eight satin woven fabrics can be woven by driving the shuttle, in which each weft yarn (20a to 20h) is fixed, into the gap between the warp yarns (crossing the warp yarns and the weft yarns).

(Organization chart)
Referring to FIG. 2, in the organization chart of the weft fabric FS, the crossing points (structure points: CD1 to CD8) of the warp yarn and the weft yarn are flying so as not to be regularly arranged. Call it "number".
The organization chart can divide a given number of warps (the number of warp yarns of a complete organization) into 1 and 2 numbers having no common divisor, and draw these 2 numbers as “the number of flying lions”.
For example, since the number of cocoons in an eight-sheet satin fabric is eight, the “number of vermilion flying” is any one of (1 and 7, 3, and 5, 2, 6, 4, and 4). Of these, (1 and 7), (2 and 6), and (4 and 4) are excluded because they have a relationship of 1 and a common divisor. Therefore, the “number of flying lions” of the eight woven fabrics is (3 and 5) (see FIGS. 2 and 3).

When “the number of flying lions” is set to 3, it is possible to draw an organization chart of three flying eight lions (an example of eight folds of red woven fabric) (see FIG. 2). In this three-five eight satin, eight texture points (CD1 to CD8) are regularly arranged with three warp yarns separated in the weft yarn direction.
In addition, when “the number of flying lions” is set to 5, it is possible to draw an organization chart of five flying eight lions (another example of eight lions fabric) (see FIG. 3). In this three-five eight satin, eight texture points (CD1 to CD8) are regularly arranged at a distance of five warp yarns in the weft yarn direction.
In these eight satin fabrics, the respective tissue points are regularly arranged at approximately equal distances. For this reason, in the eight-sheet satin woven fabric, the texture points are not easily connected to each other in a streak shape (the scarce line hardly appears), and the fabric is excellent in design.

(Thread structure)
Here, examples of the warp yarn and the weft yarn (material) include natural fibers, chemical fibers, and blended fibers thereof. These fiber wires (filaments and spun yarns) can be used as warp yarns and weft yarns. As the fiber wire, a single filament or a multifilament in which a plurality of filaments are set (crimped) can be used. Further, the covering yarn may be spirally wound around the weft yarn.
Here, the thickness (size) of the warp yarn and the weft yarn is not particularly limited as long as the weft woven fabric FS can be woven, but a typical warp yarn is 75 denier (d) to 300 denier (d). . The weft yarn is 0.001 denier (d) to 300 denier (d).
In particular, it is preferable to use a single fiber denier 0.001d to 1d long fibers (including crimped long fibers) as the weft.

Examples of natural fibers include animal-based natural fibers and plant-based natural fibers, and it is preferable to use silk having excellent gloss.
In addition, synthetic fibers such as polytrimethylene terephthalate (PTT), polyethylene terephthalate (PET), polypropylene (PP), polybutylene terephthalate (PBT), and polylactic acid (PLA) can be used as chemical fibers. As the chemical fiber, regenerated fiber such as rayon or semi-synthetic fiber such as acetate can be used.

And when weaving the horizontal satin fabric FS, it is desirable to make the surface of the fabric further uneven by the following methods (a) to (c).
(A) The weft satin fabric FS is composed of weft yarns having different thicknesses. For example, the surface of the fabric can be made uneven by driving a thick weft thread and a thin weft thread alternately or randomly.
For example, referring to FIG. 2, a portion of the weft yarn (20a, 20c, 20e, 20g) is formed of a thick yarn. Further, the weft thread other parts (20b, 20d, 20f, 20h) are constituted by thin threads. When a multifilament weft is used, the thickness of the yarn can be adjusted by the number of constituent yarns (the number of filaments).

Further, it is preferable that the single yarn denier 0.001d to 1d weft yarn (A) and the single yarn denier 2d to 10d weft yarn (B) are twisted together or alternately driven. The weft yarn (A) and the weft yarn (B) are both long fibers (including crimped long fibers).
At this time, it is preferable to set a large difference between the total denier numbers of (A) and (B) (preferably (A) − (B) ≧ 20). By setting the difference in the total denier number between the weft yarn (A) and the weft yarn (B) in this way, the weft fabric FS can be easily uneven, and the actual contact area (M) with the leather LS is reduced. .
The abnormal noise generation energy (E) can be obtained by the following calculation formula.
Abnormal noise generation energy (E) = vertical load (N) × dynamic friction coefficient (μ) × actual contact area (M) × contact time (t)

(B) The weft satin fabric FS is composed of weft yarns having different heat shrinkage rates. That is, a weft yarn having a high shrinkage rate and a weft yarn having a low shrinkage rate are driven alternately or randomly. And the fabric surface can be made uneven by heat-treating the fabric and shrinking the weft yarn.
The shrinkage rate of the weft yarn (single filament or multifilament) can be adjusted by, for example, the material of the yarn. When the covering yarn is wound around the weft yarn, the heat shrinkage rate of the covering yarn may be adjusted (the degree of convergence of the weft yarn by the covering yarn may be different).

(C) The weft fabric FS is composed of weft yarns (multifilaments) having different numbers of twists. That is, the weave surface can be made more uneven by alternately or randomly driving a weft yarn with a large number of twists (a weft yarn strongly tightened) and a weft yarn with a small number of twists.
At this time, it is also possible to use a plurality of weft yarns (a plurality of weft yarns grouped together without being twisted together).

(Raising or fluffing treatment)
The weft yarn or fluffing treatment is applied to the weft yarn of the weft satin fabric FS. With reference to FIG. 4, the weft treatment or fluffing treatment is applied to the weft yarn 20 a, whereby the weft yarn 20 a can be further raised from the fabric surface (the fabric surface becomes more uneven).
Here, the raising process is a process for drawing the weft 20a in the weft satin fabric FS to the fabric surface (see FIG. 4B). The raising method is not particularly limited. For example, the weft 20a can be drawn from the fabric surface by a raising machine (a machine having a J-shaped fitting attached to a cylinder).
The fluffing process is to cause the fibers of the weft thread 20a to protrude into a fluff shape by scratching the weft thread 20a in the weft satin fabric FS (see FIG. 4C). The method of fluffing treatment is not particularly limited. For example, the weft yarn 20a can be scratched and made fluffed by a member such as a splinter.

(Embossing)
Moreover, in a present Example, embossing can be given to the horizontal satin woven fabric FS. Here, the embossing method is not particularly limited. For example, the woven fabric can be made uneven by rolling a surface uneven roll while pressing the roll against the horizontal satin fabric FS.
And by embossing the horizontal satin fabric FS to make it uneven, the lateral satin fabric FS has a design that approximates the leather LS. In particular, by forming leather-like irregularities on the eight satin fabrics, the fabrics have a design (high-quality texture) comparable to the leather LS.

(Disposition of skin material)
With reference to FIG.1 and FIG.2, the skin material part of the 1st contact part 11 (seat back 6 bottom part) is comprised with the horizontal satin fabric FS. Thus, the design property of a sheet | seat can be maintained suitably by arrange | positioning the horizontal satin fabric FS in the seat back 6 bottom part (position which is not conspicuous).
And the weft yarn of the weft satin fabric FS is arranged orthogonal to the friction direction when the seat back 6 is tilted. That is, the weft yarn (20a to 20h) of the weft satin fabric FS is arranged orthogonal to the up-down direction D1 (vehicle longitudinal direction) of the seat back 6. Here, it is desirable that the weft yarns are arranged orthogonal to the up-and-down direction. However, the weft yarns do not need to be strictly orthogonal and can be arranged slightly inclined.

When the seat back 6 is raised and lowered, the first contact portion 11 (the seat back 6 bottom portion) contacts the second contact portion 12 (the rear portion of the seat cushion 4) and relatively moves.
At this time, the weft yarns (20a to 20h) of the first contact portion 11 sequentially contact the second contact portion 12 (leather LS). Since these weft yarns (20a to 20h) are raised from the fabric surface, they come into point contact with the second contact portion 12 (the contact area is reduced).
Further, by arranging the weft yarns (20a to 20h) perpendicular to the up-and-down direction D1 of the seat back 6, the weft yarns and the second contact portion 12 are separated in a relatively short time (friction stress). Residue is preferably avoided).
Thus, by reducing the contact area between the first contact portion 11 and the second contact portion 12 and avoiding residual stress of each weft yarn, it is possible to prevent or reduce the generation of abnormal noise due to friction as much as possible.

As described above, according to the present embodiment, the horizontal satin fabric FS having excellent design properties is used. Moreover, the generation of noise due to friction between the skin materials 4S, 6S can be prevented or reduced by bringing the weft yarn of the weft satin fabric FS (the weft yarn floating from the fabric surface) into contact with the leather LS.
For this reason, according to the present embodiment, it is possible to prevent or reduce the generation of abnormal noise during sheet operation while maintaining the design of the skin material 6S as much as possible.
In particular, the 8 satin woven fabric has excellent design properties, so that the design properties of the sheet can be suitably improved. Further, by embossing the eight satin fabrics, the lateral satin fabrics FS have a texture comparable to the leather LS.
For this reason, according to the 8 satin woven fabric of the present embodiment, it is possible to prevent or reduce the generation of abnormal noise while maintaining the texture in the vehicle seat 2 (a sheet mainly composed of a leather skin material).

<Example 2 (reference example) >
Since the vehicle seat 2a of the present embodiment has substantially the same basic configuration as that of the vehicle seat of the first embodiment, common structures and the like are denoted by corresponding reference numerals and detailed description thereof is omitted.
The vehicle seat 2a in FIG. 5 includes a pair of seat bodies 31a and 32a and an armrest 9. The pair of seat bodies 31a and 32a includes a seat cushion 4a, a seat back 6a, and a headrest 8a, respectively. A storage portion 40 (substantially rectangular space) capable of storing the armrest 9 is formed between the pair of seat backs 6a, 6a.

The armrest 9 is a substantially rectangular member and is exclusively covered with a skin material made of leather.
In this embodiment, one side of the armrest 9 is pivotally supported on a shaft portion (not shown) bridged to the storage portion 40. By rotating the armrest 9, it is possible to displace between a “use position” where the other side of the armrest 9 protrudes forward of the seat and a “storage position” where the armrest 9 is accommodated in the storage portion 40.
However, in the above configuration, when the armrest 9 rotates, the side surface of the armrest 9 (first contact portion 11a) and the side surface of the seat back 6a (second contact portion 12a) may come into contact with each other to generate abnormal noise.
Therefore, in the present embodiment, the skin material portion of the first contact portion 11a is configured by the horizontal satin fabric FS, and the skin material portion of the second contact portion 12a is configured by the leather LS (see FIG. 6). The weft yarn of the weft satin fabric FS is arranged to be orthogonal to the rotational operation direction D2 (friction direction) of the armrest 9.

When the armrest 9 rotates, the first contact portion 11a (side surface of the armrest 9) contacts the second contact portion 12a (side surface of the seat back 6a) and relatively moves.
At this time, the weft yarn (20a to 20h) of the first contact portion 11a sequentially contacts the second contact portion 12a (leather LS) (see FIGS. 2 and 3). Since these weft yarns (20a to 20h) are raised from the fabric surface, they come into point contact with the second contact portion 12a (the contact area is reduced).
Further, by arranging the weft yarns (20a to 20h) perpendicularly to the rotation direction D2 of the armrest 9, each weft yarn and the second contact portion 12a are separated in a relatively short time (the frictional stress remains). To be avoided).
Thus, by reducing the contact area between the first contact portion 11a and the second contact portion 12a and avoiding the residual stress of the weft yarn, it is possible to prevent or reduce the generation of abnormal noise when the armrest 9 is operated as much as possible. .

<Example 3 (reference example) >
The vehicular seat 2b of the present embodiment has substantially the same basic configuration as the vehicular seat of the first or second embodiment, and therefore, common structures and the like are denoted by corresponding reference numerals and detailed description thereof is omitted.
The vehicle in FIG. 6 includes a vehicle seat 2b and a pair of wheel houses H1 (other members different from the vehicle seat).
The pair of wheel houses H1 are semicircular convex portions that bulge to the inside (both sides) of the passenger compartment RO, and are disposed behind the vehicle seat 2b. A clearance is provided between the pair of wheel houses H1 so that the vehicle seat 2b can be fitted therein.

The vehicle seat 2b includes a seat cushion 4b and a seat back 6b that are long in the vehicle width direction. In the present embodiment, the seat back 6b can be displaced between the “standing posture” where the seat back 6b stands up and the “flat posture” which is substantially horizontal behind the vehicle by the raising / lowering operation of the seat back 6b. The seat back 6b in a flat posture is placed between the pair of wheel houses H1 so as to fit.
However, in the above configuration, the side surface of the seat back 6b (contact portion 11b) and the side surface of the wheel house H1 (contacted portion 12b) may come into contact with each other, and abnormal noise may be generated due to friction.
Therefore, in the present embodiment, the skin material portion of the contact portion 11b is configured by the horizontal satin fabric FS, and the skin material portion of the contacted portion 12b is configured by the leather LS (see FIG. 6). Then, the weft yarn of the weft satin fabric FS was arranged orthogonal to the up and down operation direction D3 (friction direction) of the seat back 6b.

When the seat back 6b is raised and lowered, the contact portion 11b (side surface of the seat back 6b) contacts the contacted portion 12b (side surface of the wheel house H1) and relatively moves.
At this time, the weft yarns (20a to 20h) of the contact portion 11b sequentially contact the contacted portion 12b (leather LS) (see FIGS. 2 and 3). Since these weft yarns (20a to 20h) are raised from the fabric surface, they come into point contact with the contacted portion 12b (the contact area is reduced).
Further, by arranging the weft yarns (20a to 20h) perpendicularly to the up-and-down direction D3 of the seat back 6b, each weft yarn and the contacted portion 12b are separated in a relatively short time (residual stress of friction). Is avoided).
Thus, by reducing the contact area between the contact portion 11b and the contacted portion 12b and avoiding the residual stress of the weft yarn, it is possible to prevent or reduce the generation of abnormal noise when the seat back 6b operates.

<Example 4 (reference example) >
Since the vehicle seat 2c of the present embodiment has substantially the same basic configuration as any one of the vehicle seats of the first to third embodiments, common structures and the like are denoted by corresponding reference numerals and detailed description thereof is omitted. .
The vehicle in FIG. 7 includes a vehicle seat 2c (a pair of seat bodies 31c and 32c), a pair of rail members 35, and a pair of wheel houses H2. The pair of wheel houses H2 are semicircular convex portions that bulge inside the passenger compartment RO, and are disposed on both sides of the vehicle seat 2b.
Each of the pair of rail members 35 includes an upper rail 34 and a lower rail 36. Both the upper rail 34 and the lower rail 36 are plate-like members extending in the front-rear direction of the seat. The lower rail 36 is disposed in the passenger compartment, and the upper rail 34 is fixed to the lower portion of the seat cushion 4c.

The vehicle seat 2c can be fixed to the wheel house H2. That is, a reinforcing member 50 (bar shape) that is long in the vehicle width direction is attached to the seat back 6c. A support member 52 capable of supporting the reinforcing member 50 is provided on the upper surface of the wheel house H2. The support member 52 (upper part) has a screw hole 54 into which a shaft member (not shown) can be inserted.
Then, both ends of the reinforcing member 50 are attached to the supporting member 52 so as to be slidable forward and backward. Then, by inserting a shaft member (not shown) into the screw hole 54 of the support member 52, the reinforcing member 50 (vehicle seat 2c) can be fixed to the wheel house H2.

In this embodiment, the upper rail 34 and the lower rail 36 are assembled so as to be slidable forward and backward. Accordingly, the vehicle seat 2c can be slid forward and backward along the rail member 35 by releasing the fixation with the wheel house H2.
However, in the above configuration, the side surface (contact portion 11c) of the seat cushion 4c may bulge in the vehicle compartment width direction due to the seating of the occupant. For this reason, at the time of sliding movement, the wheel house H2 side surface (contacted portion 12c) and the contact portion 11b may come into contact with each other and noise may be generated.
Therefore, in the present embodiment, the skin material portion of the contact portion 11c is configured by the horizontal satin fabric FS, and the skin material portion of the contacted portion 12c is configured by the leather LS (see FIG. 7). Then, the weft yarn of the weft satin fabric FS was arranged orthogonal to the sliding motion direction (friction direction) of the vehicle seat 2c.

During the sliding movement of the vehicle seat 2c, the contact portion 11c (side surface of the seat cushion 4c) contacts the contacted portion 12c (side surface of the wheel house H2) and relatively moves.
At this time, the weft yarns (20a to 20h) of the contact portion 11c sequentially contact the contacted portion 12c (leather LS) (see FIGS. 2 and 3). Since these weft yarns (20a to 20h) are raised from the fabric surface, they come into point contact with the contacted portion 12c (the contact area is reduced).
Further, by arranging the weft yarns (20a to 20h) perpendicular to the sliding movement direction of the vehicle seat 2c, the weft yarns and the contacted portion 12c are separated in a relatively short time (residual stress of friction). Is avoided).
Thus, by reducing the contact area between the contact portion 11c and the contacted portion 12c and avoiding residual stress of the weft yarn, it is possible to prevent or reduce the generation of abnormal noise when the vehicle seat 2c slides as much as possible. it can.

The vehicle seat of the present embodiment is not limited to the above-described embodiments, and various other embodiments can be taken.
(1) In the present Example, the 1st contact part (11,11a) was comprised only with the horizontal satin fabric. In contrast to this, the second contact portion (12, 12a) can be made of a horizontal satin fabric, and the first contact portion (11, 11a) can be made of leather. Moreover, both a 1st contact part and a 2nd contact part can also be comprised with a horizontal satin fabric. The horizontal satin fabric may be in contact with the second contact portion with the back vermilion, or may be in contact with the second contact portion with the front vermilion.
The skin material portion other than the first contact portion (or the second contact portion) is preferably covered with a leather skin material in consideration of the design of the sheet, but is not limited to leather.
