Description

The present invention relates to a cover member that covers an interior material such as a chair having irregularities.

Conventionally, a seat cover formed by sewing a plurality of skin materials has been known (Patent Document 1).
The seat cover is provided at a sewn portion of two sewn skin materials, and is locked to a locking portion of the cushion pad in a state where the sewn portion is pulled into a cushion pad of a seat covered by the seat cover. The seam allowance of one of the two skin materials included in the sewn portion is a seam allowance of the other skin material in at least a part of the extending direction of the seam allowance. Has a projecting portion that is arranged so as to project in the retracting direction of the sutured portion, and the locked portion is directly provided on the projecting portion.

JP, 2017-140186, A

However, since the seat cover described in Patent Document 1 requires that a plurality of skin materials be sewn, a sewing process is inevitably generated, and the manufacturing efficiency is reduced by the sewing process.
Further, in the seat cover of Patent Document 1, when leather (natural leather, synthetic leather) or the like is used as a skin material, the skin material is sewn along the unevenness of a three-dimensional object such as a car seat, There is a problem that wrinkles occur on the surface material.

In view of such a point, the present invention has an “improvement in manufacturing efficiency” and “suppression of wrinkles” because the cover member integrally formed of the weft knitted fabric has an uneven portion that can follow the unevenness of a chair or the like. An object is to provide a cover member that realizes the above.

The cover member 1 according to the present invention is a cover member that covers an interior material C having irregularities D, and the cover member is integrally formed of weft knitted fabric, and the cover member is expandable and contractible when expanded. A first feature is that a force is generated in the direction to move and that the uneven portion 2 that can follow the unevenness D of the interior material C is provided.

A second feature of the cover member 1 according to the present invention is that, in addition to the above first feature, the uneven portion 2 is formed by flechage knitting.

A third feature of the cover member 1 according to the present invention is that, in addition to the above-mentioned second feature, the flechage knitting is provided at a plurality of positions with a predetermined distance therebetween and dispersed.

A fourth characteristic of the cover member 1 according to the present invention is that, in addition to the above first to third characteristics, the cover member is attached to the interior material C by using a surface fastener 3.

A fifth characteristic of the cover member 1 according to the present invention is that, in addition to the fourth characteristic, the interior material C is a chair C′, and the cover member is a lower surface (bottom surface) of the chair C′. At least one of the side, the unevenness D of the chair C′, and the vicinity of the unevenness D of the chair C′ is attached by using the hook-and-loop fastener 3.

The sixth feature of the cover member 1 according to the present invention is, in addition to the above fourth or fifth feature, the surface fastener 3 is a male surface fastener 3′, and the male surface fastener 3′ is a pile. The point is that it is a pile cloth having a molten mass.

A seventh characteristic of the cover member 1 according to the present invention is that, in addition to the above first to sixth characteristics, the yarn for knitting the weft knitted fabric includes a heat fusion yarn.

An eighth characteristic of the cover member 1 according to the present invention is that, in addition to the above first to seventh characteristics, the yarn knitting the weft knitted fabric includes an elastic yarn.

A ninth feature of the cover member 1 according to the present invention is a cover member that covers the interior material C, the cover member being integrally formed of weft knitted fabric, and the cover member being substantially along the vertical direction thereof. The vertical exposure length R1 of the vertical cross section is that it has a vertical exposure length difference portion 11 which differs depending on the horizontal position where the vertical cross section exists.

The tenth feature of the cover member 1 according to the present invention is a cover member for covering the interior material C, the cover member being integrally formed of weft knitted fabric, and the cover member being substantially along the horizontal direction. The lateral exposure length R2 of the cross section has a lateral exposure length different portion 12 that differs depending on the vertical position where the cross section exists.

Due to these characteristics, by integrally forming the cover member 1 with a weft knitted fabric, unlike in Patent Document 1, a sewing process such as sewing a plurality of skin materials does not occur. Is improved (“improved manufacturing efficiency”).
Along with this, by providing the cover member 1 which is expandable and contractible and in which a force is generated in a direction of contracting when expanded, with the uneven portion 2 capable of following the unevenness D of the interior material C, a car seat which is a three-dimensional object (automobile chair) Even if the interior material C such as C′ has irregularities D, it is possible to suppress the occurrence of wrinkles in the cover member 1 (“wrinkle suppression”).
It can be said that such a cover member 1 is an "integrated cover member".

Further, the cover member 1 is formed by the flechage knitting on the uneven portion 2, or the flechage knitting is provided at a plurality of positions with a predetermined distance and dispersed, so that the unevenness D of the interior material C such as the chair C′ is Thus, the uneven portion 2 of the cover member 1 can be made to follow more accurately (“improvement of followability”).

Further, the interior material C is attached to the cover member 1 by using the surface fasteners 3, or the cover member 1 is attached to the lower surface side of the chair C′ which is the interior material C, the unevenness D itself, or a portion near the unevenness D. By attaching the male fasteners 3'which are the fasteners 3 to each other by using pile fabric, it is possible to further improve "following ability" with respect to the unevenness D of the interior material C such as the chair C'. Can be achieved.

In addition, by including the heat-fusible yarn in the yarn for knitting the weft knitted fabric, when the cover member 1 is covered on the chair C′ or the like, the entry/exit durability of the cover member 1, the friction fastness, etc. are increased (“ Improving entry/exit durability”).
Further, by including the elastic yarn in the yarn for knitting the weft knitted fabric, the constant load setting rate of the cover member 1 when the cover member 1 is covered with the chair C′ or the like is increased (“constant load setting rate, etc. Improvement”).

<Overall structure of cover member 1>
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
1 to 5 show a cover member 1 according to the present invention, and this cover member 1 is a cover for covering an interior material C such as a chair C′ having an unevenness D.
First, the interior material C and the like covered by the cover member 1 will be described below.

<Interior material C, chair C', unevenness D>
As shown in FIGS. 1 to 3, the interior material C is a chair or interior material (inner wall material, ceiling material, floor material, etc.) inside (inside) a vehicle such as an automobile (passenger car), railroad vehicle, aircraft, or ship. Especially for automobiles, car interiors (chairs), ornaments (door trims), armrests, seat belt storage covers, dashboards, glove boxes, instrument panels, console boxes, etc. , Ceiling materials and floor materials are also included).
The interior material C is not only the interior of vehicles such as automobiles described above, but also furniture such as chairs and beds in interiors of buildings such as houses and buildings, interior materials such as wall materials, ceiling materials, floor materials, and lighting equipment. And so on.
The following description will be made assuming that the interior material C is mainly a chair (particularly, a car seat) C′.

The chair C′, which is one of the interior materials C, is seated by a user such as a driver, a passenger, or an office worker. In addition to the car seat of the above-described passenger car, if a user can sit in the office, It may be a chair, a relax chair, a lounge chair, a dining chair, a stool, a bench, or the like.
The chair C′ is not particularly limited in its shape, color, material, etc., and may or may not have a headrest, an armrest, or a backrest.
Hereinafter, the chair C'is mainly described as a car seat.

The unevenness D in the interior material C such as a car seat means a dent and/or a ridge (protrusion).
Particularly, in the case of a chair C′ such as a car seat, the unevenness D is mainly provided in the seat portion C1′ and the backrest portion C2′.

Here, the seat portion C1' of the chair C'is a portion that supports the user (especially, the lower half of the body from the buttocks to the thighs) from below when the user such as a driver sits down. A portion where the seat portion C1′ and the user come into contact (usually, a portion which is substantially in the center in the left-right direction and has a predetermined range in the front-rear direction) is recessed (curved downward), and is a recess in the unevenness D. I can say.
It can be said that the portions where the seat portion C1' and the user do not come into contact (normally, the end portions in the left-right direction) are raised (curved upward) in the opposite manner, and it can be said that the unevenness D is raised.

Further, the backrest portion C2' of the chair C'is a portion that supports the user (especially, the back side from the buttocks to the back) when the user such as a driver sits down, and The portion where the backrest portion C2′ and the user come into contact (usually, the portion which is substantially in the center in the left-right direction and in a predetermined range in the substantially vertical direction) is recessed (curved rearward), and the unevenness D is formed. It can be said that it is a dent.
In addition, it can be said that the portion where the user does not come in contact with the backrest portion C2′ (usually each end portion in the left-right direction (side portion)) is raised in the opposite direction (curved upward). , It can be said that it is a bump.
What value is the unevenness difference of the unevenness D in the interior material C (depth if it is a dent, height if it is a ridge, and if there is both a dent and a ridge, the height difference from the bottom of the dent to the top of the ridge) However, it may be, for example, 1 mm or more and 500 mm or less, preferably 3 mm or more and 100 mm or less, and more preferably 10 mm or more and 50 mm or less.

Even if the interior material C is other than the chair C′, the unevenness D includes any structure as long as it is a depression and/or a protrusion (protrusion). For example, if the interior material C is the interior material C″, In the case of a single door trim, a grip portion for gripping when a user such as a driver opens and closes the door from inside the room is provided, and the depressions or protrusions (protrusions) that make this grip portion easy to grip are uneven. It can be said that it is D.
In addition, if the interior material C is another interior material (other inner wall material, ceiling material, etc.) C″, or if it is a dent and/or a ridge (protrusion) due to decoration or a pattern, the unevenness D is formed.

<Cover member 1, integrally formed weft knitted fabric>
As shown in FIGS. 1 to 5, the cover member 1 covers the interior material C such as the chair C′ having the unevenness D described above.
The cover member 1 may cover the entire interior material C such as the chair C′, but may cover at least a part of the interior material C. For example, in the case of the chair C′, only the seat portion C1′ is provided. It does not matter whether it is divided into a plurality of members to cover both the seat portion C1' and the backrest portion C2', such as to cover the seatback portion or the backrest portion C2'.

The cover member 1 is integrally formed (integrated knitting) as a weft knitted fabric (including a circular knitted fabric), and at the same time, is expandable and contractable, and is oriented so as to contract along the predetermined direction when extended in the predetermined direction. A force is generated, and it has an uneven portion 2 described later.
In other words, it can be said that such a cover member 1 is integrally formed of a weft knitted fabric and at the same time has a longitudinally exposed long difference portion 11 described later.

In other words, it can be said that the cover member 1 is integrally formed of the weft knitted fabric, and at the same time, has the laterally exposed long difference portion 12. In any case, the cover member 1 is integrally formed of the weft knitted fabric. It has the characteristics that are described.
The cover member 1 which is an integrally formed weft knitted fabric is not particularly limited in shape and configuration as long as it can cover the interior material C such as the chair C′, but is, for example, the chair C′. In this case, the cover member 1 is a circular knitted fabric, and the shape thereof is a substantially bag shape (only one opening 1c is provided) or a substantially tubular shape (two openings 1c are directly opposite to each other). Alternatively, it may have a shape having three or more openings 1c (the basic shape is a substantially bag shape or a substantially cylindrical shape).
Through these openings 1c, for example, a member connecting the chair C'and its pedestal may be passed or a member such as a headrest may be passed.

Even when the interior material C is the interior material C″, the cover member 1 that is an integrally formed weft knitted fabric is not particularly limited in its shape and configuration. For example, the cover member 1 is not a circular knitted fabric. The weft knitted fabric may have a sheet shape or the like.
The cover member 1 which is a weft knitted fabric may be integrally formed (integrated knitting) by a predetermined knitting machine or may be integrally formed by hand knitting.
Hereinafter, the cover member 1 will be described as being integrally formed by a predetermined knitting machine.

The fibers (or yarns) forming (knitting) the cover member 1 which is an integrally formed weft knitted fabric are also not particularly limited in their material, for example, polyethylene terephthalate (PET) which is a thermoplastic material, Polyester fibers such as polytrimethylene terephthalate (PTT) and polybutylene terephthalate (PBT), nylon (polyamide) fibers, polyolefin fibers such as polyethylene (PE) and polypropylene (PP), rayon fibers, cupra fibers, acetate fibers, poly Synthetic fibers such as acrylic fiber containing acrylonitrile (PAN) as a main component, polyvinyl alcohol (PVA) fiber (vinylon fiber), polyurethane (PU) fiber (polyurethane elastic yarn) may be used, and also glass fiber, wool, silk, etc. However, these may be used alone or in combination.

<Heat fusion yarn>
Further, the yarn constituting (knitting) the cover member 1 which is an integrally formed weft knitted fabric may be, for example, a heat-fusible yarn having a heat-fusible portion and a non-heat-fusible portion. ..
The heat-fusible portion and the non-heat-fusible portion in the heat-fusible yarn are polyethylene (PE) resin and polypropylene (PP) resin, polyester resin (polyethylene terephthalate (PET) resin, polytrimethylene terephthalate ( (PTT) resin, polybutylene terephthalate (PBT) resin) and polyethylene (PE) resin or polyamide (nylon) resin, or ordinary polyester resin (high melting point polyester resin) and low melting point polyester resin may be used. Absent.

The heat-fusible yarn may have any configuration as long as it has a heat-fusible portion, but may have, for example, a core-sheath structure, a barring structure, or the like. Of the heat-fusible portion and the non-heat-fusible portion having different melting points, the non-heat-fusible portion having a higher melting point is used as a core, and the heat-fusible portion having a lower melting point is used as one yarn ( If the heat-fusible yarn 4 has a covering structure, the heat-fusible part is formed by spinning in a single fiber). It may have a structure in which a certain thread is wound.
The ratio of the heat-sealing yarns (content of the heat-sealing yarns) in the yarns for knitting the entire weft knitted fabric (that is, the cover member 1) is not particularly limited, but is, for example, 5%. It may be 60% or less and preferably 60% or less, preferably 10% or more and 50% or less, more preferably 15% or more and 45% or less. It can be said that the texture of a certain cover member 1 becomes poor.

<Elastic thread>
In addition to this, as the yarn that constitutes (knits) the cover member 1 that is the integrally formed weft knitted fabric, for example, an elastic yarn may be used.
The elastic thread may include, for example, at least one of a polyurethane (PU) resin thread and a rubber thread.
Further, the elastic yarn may have a covering structure in which a sheath yarn is wound around a core yarn.

When the elastic thread has a covering structure, the core thread is a polyurethane resin thread or a rubber thread, and the sheath thread is a heat-bonded polyester resin (for example, polyethylene terephthalate (PET) resin). It may be a thread.
Further, the elastic yarn may include the above-mentioned heat-fusible yarn having the heat-fusible portion, or may include a yarn made of other material.

The elasticity of the elastic yarn (yarn elongation) is other yarns for knitting the cover member 1 which is the weft knitted fabric (the above-mentioned heat-bonded yarn, polyester fiber yarn (so-called regular yarn), etc.) ), it can be said that the yarn elongation is high.
The elastic yarn is not particularly limited in its specific yarn elongation value. For example, the stress (unit: N (Newton)) when the elastic yarn is stretched by 15% in the longitudinal direction is 0.01 N or more. It may be 5.00 N or less, preferably 0.02 N or more and 3.00 N or less, and more preferably 0.03 N or more and 2.00 N or less.

In the present invention, "elongation" means the easiness of elongation when the yarn for knitting the weft knitted fabric is pulled in the longitudinal direction of the yarn (conversely, it is difficult to extend). Since the degree is the elongation of the yarn itself for knitting the weft knitted fabric, it can be said to be “yarn elongation”.
In addition, the ratio of the elastic yarns (content of the elastic yarns) in the yarns for knitting the entire weft knitted fabric (that is, the cover member 1) is not particularly limited, but is, for example, 10% or more and 90% or less. It may be 20% or more and 80% or less, more preferably 30% or more and 70% or less (50% or the like).

Further, the fineness of the fibers constituting the cover member 1 (knitting, weaving, etc.) may be any value, but for example, the total fineness may be 20 dtex or more and 3000 dtex or less.
The thickness of the cover member 1 may be any value, but is, for example, 0.1 mm or more and 30.0 mm or less, preferably 0.5 mm or more and 10.0 mm or less, and more preferably 1.0 mm or more and 5.0 mm or less. May be.

If desired, the cover member 1 which is an integrally formed weft knitted fabric may optionally include an extender pigment such as titanium oxide or calcium carbonate or a filler (filler), a deodorant, an antibacterial agent, an antifungal agent, A material (fiber) to which a flame retardant, a water repellent, an antifouling agent, a coloring agent, a fragrance, a foaming agent or the like is added may be used, or the cover member 1 may be treated after being formed as an integrally formed weft knitted fabric. .
The cover member 1 may have any pattern such as a plain pattern, a pattern of plants such as flowers and plants, a pattern of animals, a geometric pattern, and a pattern of surface irregularities. The color of the cover member 1 may be any color tone such as blue, black, white, red, orange, yellow, green, and violet, and the saturation and lightness may be any values. .

The "surface 1a" of the cover member 1 which is an integrally formed weft knitted fabric can be said to be a surface exposed when the interior material C such as the chair C'and the interior material C" is covered.
On the contrary, the "back surface 1b" of the cover member 1 can be said to be a surface which is not exposed when the interior material C such as the chair C'and the interior material C" is covered.

The cover member 1 may be covered (covered) in any manner as long as it can cover the interior material C such as the chair C′. For example, the cover member 1 has a substantially bag shape or a substantially cylindrical shape. If the interior material C is a chair C′, the weft direction of the cover member 1 which is a weft knitted fabric integrally formed with the chair C′ is the left-right direction of the chair C′. It is also possible to cover the cover member 1 vertically (that is, to cover it from above the backrest portion C2′ or from the front side of the seat portion C1′) so as to substantially follow the direction.
In this case, with respect to the chair C′, the cover member 1 is laterally covered so that the weft direction of the cover member 1 is substantially along the up-down direction or the front-back direction of the chair C′ (that is, the backrest portion C2′). Of the seat portion C1′ or one of the left and right sides of the seat portion C1′).

When the cover member 1 is in the form of a sheet and the interior material C is the interior material C″, the cover member 1 which is a weft knitted fabric integrally formed with the interior material C″ is used. The weft direction may be covered with the cover member 1 so as to be substantially along any of the left-right direction, the up-down direction, the front-back direction, the bias direction (oblique direction), and the like in the interior material C″.
In addition, the cover member 1 which is an integrally formed weft knitted fabric may be attached to the interior material C such as the chair C′ using the surface fastener 3 or may have a detachable member such as a string and a pocket. , And may be detachable (removable) with respect to the chair C′ and the like.

<Concavo-convex part 2, turn back>
As shown in FIGS. 1 to 5, the uneven portion 2 is a portion that can follow the unevenness D of the interior material C such as the chair C′ described above.
Here, “capable of following the unevenness D” in the present invention means that the cover member is substantially along the surface (the surface on the side covered with the cover member 1) Ca of the unevenness D in the interior material C such as the chair C′ described above. It means that the uneven portion 2 of 1 can have the same uneven shape, and even when the cover member 1 which is an integrated weft cloth covers the chair C′, the interior material C″ and the like, the uneven portion 2 is formed. In the above, the coarse stitches are suppressed, and the surfaces Ca′ and Ca″ of the unevenness (dents and/or ridges) D such as the chair C′ and the interior material C″ are not easily seen through the cover member 1. May be.

The uneven portion 2 may have any configuration (knitting structure) as long as it can follow the unevenness D of the chair C′ or the like. For example, in the cover member 1 which is an integral weft knit, the uneven portion 2 is formed by flechage knitting. May be formed.
The "pullback knitting" in the present invention means that a certain course (needle loop, number of stitches) of a weft knitted fabric (including a circular knitted fabric) is partially increased or decreased (one step in the warp direction). It means a knitting structure that rests the eyes of a part, and the number of courses (number of steps) of the weft knitted fabric varies depending on the weft direction of the weft knitted fabric (for example, the horizontal direction of the cover member 1 (the weft direction of the weft knitted fabric). The length of the cover member 1 in the vertical direction (the warp knitted fabric warp direction (course direction)) varies depending on the (wale direction)), and is also referred to as a pause knitting.

In addition, the uneven portion 2 may be configured by other than the flechage knitting by a predetermined knitting machine as long as it can follow the unevenness D of the chair C′ or the like. The specific knitting structure (knitting method) includes W&T (Wrap & Turn) flechage knitting, Japanese-style short row (Japanese Short Rows) flechage knitting, and German-style short row (German Short Rows) flechage knitting. I don't care.
Such an uneven portion 2 is provided in the cover member 1 at a position that covers the unevenness D of the interior material C such as the chair C′. In other words, the uneven portion 2 corresponds to the unevenness D of the chair C′ and the like. When viewed from the front (viewed in the normal direction on the surface Ca′ of the side covered with the cover member 1 such as the chair C′), the uneven portion 2 is provided at a position substantially overlapping the unevenness D.

The flechage knitting may form the uneven portion 2 by providing the flechage knitting at a predetermined distance and in a dispersed manner at a plurality of places. The predetermined distance is a predetermined distance in the cover member 1 which is a weft knitted fabric. The number of courses (number of steps in the longitudinal direction) may be meant, and the predetermined number of courses may be, for example, 1 course or more and 10 courses or less.
The increase/decrease in the number of courses and the position of the uneven portion 2 will be described in detail with reference to a longitudinally exposed long difference portion 11 and a laterally exposed long difference portion 12, which will be described later, and FIGS.

<Surface fastener 3, male surface fastener 3'>
As shown in FIGS. 1 to 3, the hook-and-loop fastener 3 is used when the cover member 1 described above is attached to the interior material C such as the chair C′ described above.
The surface fastener 3 may have any configuration as long as the cover member 1 can be attached to the chair C′ or the like, but may be, for example, a male surface fastener 3′ or a female surface fastener. ..

The male surface fastener 3'is a surface fastener having projections such as piles and hooks on one surface of the sheet-like material (sheet-like article), and is made of, for example, a pile cloth having a molten mass in the pile. Surface fasteners (specifically, formed by melting napped fibers composed of thermoplastic synthetic fibers having a single fiber fineness of 0.3 dtex or more and 10.0 dtex or less and a maximum dimension of 2 to 5 times the single fiber diameter of the napped fibers) A surface fastener in which the male fibers having a molten mass and the non-male fibers having no molten mass are adjacent to each other) may be used.
Further, the male surface fastener 3′ may be a surface fastener in which a broken break opening of a fiber lying in a direction parallel to the surface of the male surface fastener is exposed.
Alternatively, the male hook-and-loop fastener 3'may be a hook-and-loop fastener (Velcro (registered trademark)) having a base and a large number of engaging hooks integrally molded (cast) with the base.

The surface fastener 3 such as the male surface fastener 3'is not particularly limited as long as it is used when the cover member 1 is attached to the chair C'or the like, but the surface fastener 3 is the chair C'or the like. At the same time as the interior material C side, the pile side surface (male surface) having the molten mass and the surface (female surface) to which protrusions such as piles can be attached are exposed. The pair of surface fasteners 3 may be attached to the cover member 1 side with the female surface or the male surface exposed.
In this case, the surface fasteners 3 on the side of the interior material C such as the chair C′ and the surface fasteners 3 on the side of the cover member 1 are engaged with each other to attach the cover member 1 to the chair C′ or the like using the surface fasteners 3. Will be made.

The surface fastener 3 has a pair of male surface fasteners 3'and female surface fasteners attached only to the cover member 1 side in a state where the male surface and the female surface are exposed. Is also good.
In addition, if the cover member 1 itself, which is a weft knitted fabric, can be engaged with the male surface fastener 3', the surface fastener 3 has only the male surface fastener 3'only for the cover member 1 side. It may be attached with the surface exposed.

The method and means for enabling the cover member 1 itself, which is a weft knitted fabric, to engage with the male surface fastener 3'is not particularly limited, but for example, the weft knitted fabric integrally formed as the cover member 1 can be used. A fluff (pile) obtained by raising a predetermined portion of the above may be provided with a molten mass by a laser beam irradiation device, a flame radiating device, an ultrasonic sewing machine, or the like.
The method and means for attaching the surface fastener 3 to the cover member 1 side or the interior material C side such as the chair C′ are not particularly limited, but are attached, for example, by sewing or via an adhesive such as glue. May be.

The position at which the hook-and-loop fastener 3 is provided is also not particularly limited. For example, when the interior material C is a chair C′, it is used to attach the cover member 1 to the lower surface (bottom surface) side of the chair C′. Or the unevenness D of the chair C′ (the depression and/or the ridge of the chair C′, the portion from the depression to the ridge) itself, or the portion near the chair C′ (the portion of the dent and/or the protrusion of the chair C′). The surface fastener 3 may be used to attach the cover member 1 to the.
In this case, a pair of male surface fasteners 3'and female surface fasteners are formed on the lower surface side of the chair C'and on the concave and convex portions D and in the vicinity of the concave and convex portions D, at positions corresponding to the chair C'side and the cover member 1 side, respectively. If the cover member 1 itself is engageable with the male surface fastener 3', the pair of male surface fasteners 3'and the female surface fasteners are attached only to the cover member 1 side, Only the male surface fastener 3′ may be attached only to the member 1 side.
Hereinafter, the surface fastener 3 will be described in detail as a male surface fastener 3'.

<Vertical exposure length difference portion 11, vertical cross section T1, vertical exposure length R1>
As shown in FIGS. 1 to 3, the vertical exposure length difference portion 11 is a portion where the vertical exposure length R1 in the vertical cross section T1 of the cover member 1 differs depending on the horizontal position where the vertical cross section T1 exists.
Here, the “longitudinal section T1” in the present invention is a section that is substantially along the vertical direction (vertical direction) of the cover member 1, and this vertical section T1 is the interior member C such as the cover member 1 and the chair C′. It can be said that it is a cross section in a horizontal direction (for example, a left-right direction view) at a predetermined horizontal position (for example, a predetermined left-right position).
In particular, FIGS. 2A to 2C show a vertical cross section T1 existing at a predetermined horizontal position (a certain horizontal position, another horizontal position, and still another horizontal position).

Further, the "vertical exposure length R1" in the present invention means the length in the vertical cross section T1 of the exposed portion when the interior member C such as the chair C'is covered with the cover member 1.
Therefore, in FIG. 2 in the case where the interior material C exemplifies the chair C′, the circumference indicated by a thin solid line surrounding the chair C′ (thick solid line) in the vertical section T1 at each horizontal position of (a) to (c). The length becomes each vertical exposure length R1, and this vertical exposure length R1 is different in each horizontal position (in FIG. 2, each horizontal position) where the vertical cross section T1 exists in the cover member 1. I understand.

Therefore, it can be said that the portions having different vertical exposure lengths R1 (different from each other) depending on the horizontal position become the vertical exposure length different portions 11, and the vertical exposure length R1a in the vertical cross section T1a of FIG. Since the vertical exposure length R1b in the vertical cross section T1b in (b) and the vertical exposure length R1c in the vertical cross section T1c in FIG. 2(c) are different from each other, a portion 11a including the vertical cross section T1a in FIG. It can be said that the portion 11b including the vertical cross section T1b of FIG. 2B and the portion 11c including the vertical cross section T1c of FIG. 2C are mutually different vertically exposed long difference portions 11 (11a to 11c). ..
Further, it can be said that the entire portion including the vertically exposed long difference portions 11a to 11c is the vertically exposed long difference portion 11.
Further, in the vertical exposure length different portion 11, the difference in the vertical exposure length R1 may be substantially left-right symmetry (generally symmetrical at the left-right position) or substantially front-back symmetry (generally symmetrical at the front-back position). The entire portion in which the vertical exposure lengths R1 are symmetrically different from each other may be set as one vertical exposure length difference portion 11.

<Different lateral exposure length 12, cross section T2, lateral exposure length R2>
As shown in FIGS. 1 to 3, the laterally exposed length different portion 12 is a portion where the laterally exposed length R2 of the cover member 1 at the lateral cross section T2 differs depending on the vertical position where the lateral cross section T2 exists.
Here, the “transverse cross section T2” in the present invention is a cross section substantially along the horizontal direction of the cover member 1, and this cross section T2 is a predetermined vertical direction of the interior material C such as the cover member 1 and the chair C′. It can also be said that it is a cross section in a vertical direction (a vertical direction) at a position (a predetermined vertical position).
In particular, (a) to (c) of FIG. 3 show a cross section T2 existing at a predetermined vertical position (a certain vertical position, another vertical position, and yet another vertical position).

Further, the "lateral exposure length R2" in the present invention means the length in the vertical cross section T1 of the exposed portion when the interior material C such as the chair C'is covered with the cover member 1.
Therefore, in FIG. 3 in the case where the interior material C exemplifies the chair C′, the circumference indicated by a thin solid line surrounding the chair C′ (thick solid line) in the cross-section T2 at each vertical position of (a) to (c). The length becomes each lateral exposure length R2, and this lateral exposure length R2 differs depending on each vertical position (each vertical position in FIG. 3) where the transverse section T2 exists in the cover member 1. I understand.

Therefore, it can be said that the portions having different horizontal exposure lengths R2 (different from each other) depending on the vertical position become the horizontal exposure length different portions 12, and the horizontal exposure length R2a in the horizontal cross section T2a of FIG. Since the horizontal exposure length R2b in the horizontal cross section T2b in (b) and the horizontal exposure length R2c in the horizontal cross section T2c in FIG. 3(c) are different from each other, the portion 12a including the horizontal cross section T2a in FIG. The portion 12b including the cross-section T2b of FIG. 3B and the portion 12c including the cross-section T2c of FIG. 3C can be said to be mutually different lateral exposure long difference portions 12 (12a to 12c). ..
Further, it can be said that the entire portion of the laterally exposed long difference portions 12a to 12c is the laterally exposed long difference portion 12.
In the lateral exposure length difference portion 12, the difference in the lateral exposure length R2 may be substantially vertically symmetrical (generally symmetrical in the vertical position), and the lateral exposure length R2 is substantially vertically symmetrical. The entire exposed portion may be one laterally exposed long difference portion 12.

<Detailed explanation of each exposed length difference portion 11 and 12 and the uneven portion 2>
As shown in FIGS. 4 and 5, each of the exposed length different portions 11 and 12 and the uneven portion 2 described above are provided on the cover member 1 which is an integrally formed weft knitted fabric.
Based on the weft knitting data of the cover member 1, how to provide the portions 11 and 12 having different exposed lengths R1 and R2 and the uneven portion 2 that follows the unevenness D of the interior material C will be described below. ..
In the cover member 1 which is an integrally formed weft knitted fabric, the warp direction (course direction) is the vertical direction (vertical direction) in FIGS. 1 to 3, and the weft direction (wale direction) is the horizontal direction in FIGS. It is assumed that the chair C′ is covered from above the backrest portion C2′ so as to be in the left/right position or the front-back direction.

In FIGS. 4 and 5, the portion of the cover member 1 where the stitches (needle loops) are formed is represented by “bright color (light color)”, and the cover member 1 is not formed with stitches (the stitch formation is suspended. ) Portion is represented by "dark color (dark color or almost black)".
In particular, in FIG. 5 in which the weft knitting data of the uneven portion 2 is enlarged, from the number of “light colors” (that is, the number of side courses in the side portion) N1 at the weft direction position (side portion) indicated by the arrow A, The number of “bright colors” N2 (that is, the number of central courses in the substantially central portion) N2 at the position in the latitudinal direction (approximately the central portion) indicated by the arrow B in FIG. 5 is larger than that in the side portion. The fabric of the weft knitted fabric is left over in the central part (dubbed).

When the cover member 1 is covered from above the backrest portion C2' of the chair C', this is the number of side courses N1 (horizontal position, etc.) corresponding to the weft direction position indicated by the arrow A ( That is, from the vertical exposure length R1 of the side portion, the central course number N2 (that is, the vertical exposure length R1 of the substantially central portion) at the horizontal position (horizontal position, etc.) corresponding to the weft direction position indicated by the arrow B. ) Means that it will be longer. Therefore, it can be said that the vertically exposed long difference portion 11 is the uneven portion 2.
At the same time, when the cover member 1 is covered from one of the left and right sides of the chair C′, the number of side courses N1 (that is, the side portion) at the vertical position (vertical position) corresponding to the weft direction position indicated by the arrow A. The lateral exposure length R2) of the center course number N2 (that is, the lateral exposure length R2B of the substantially central portion) at the vertical position (vertical position) corresponding to the latitudinal direction position indicated by the arrow B is longer. This means that the laterally exposed long difference portion 12 is also the uneven portion 2.

Therefore, in the uneven portion 2 (each exposed length difference portion 11 and 12) of FIG. 5, the magnification of the central course number N2 with respect to the side course number N1 (N2/N1, hereinafter “unevenness rate α”) is There are differences (see <1> to <5> in FIG. 5) depending on the longitudinal position (vertical position). The number of side courses N1, the number of central courses N2, and the side for each of the uneven portions of <1> to <5>. Table 1 below shows the difference (N1-N2) between the number N1 of courses and the number N2 of central courses and the unevenness rate α (N2/N1).
In addition, the portions <1> to <5> in FIG. 5 correspond to the uneven portions (recessed portions) of <1> to <5> in FIG. 2 when the cover member 1 is put on the chair C′. From FIG. 2, it can be said that the uneven portion of <1> is “upper shallow uneven portion”, the uneven portion of <2> is “upper deep uneven portion”, the uneven portion of <3> is “deepest uneven portion”, < It can be said that the uneven portion of 4> is a “lower deep uneven portion” and the uneven portion of <5> is a “lower shallow uneven portion”.

As shown in Table 1, the unevenness ratio α between the side portion and the substantially central portion is 1.43 in the upper shallow uneven portion of <1> and 1.79 in the upper deep uneven portion of <2>. 2.03 in the deepest uneven portion of <3>, 1.94 in the lower deep uneven portion of <4>, 1.35 in the lower shallow uneven portion of <5>, and unevenness of <1> to <5> It was found that if the portions were set to be 1.69 on average, the uneven portion 2 (each exposed length difference portion 11, 12) capable of following the unevenness (dent) D of the chair C′ was obtained.
Here, the unevenness rate α of each uneven portion of <1> to <5> is not limited to the value of Table 1 described above, and by adjusting the flechage knitting in the uneven portion 2 appropriately, for example, with the side portion. The unevenness ratio α with the substantially central portion is set to, for example, 1.10 or more and 1.45 or less in a shallow unevenness portion (low unevenness portion) such as <1> or <5>, and <2> or <4>. The deep unevenness portion (high unevenness portion) may be set to 1.45 or more and 1.80 or less, and the deepest unevenness portion (highest unevenness portion) such as <3> may be set to 1.80 or more and 2.30 or less. ..
In this way, by adjusting the unevenness ratio α of the unevenness portion 2 (each exposed length difference portion 11, 12) to be increased or decreased, the unevenness D having various depths/heights in the interior material C or gradually becoming deeper. The cover member 1 is capable of following the unevenness D (which gradually increases).
