Description

  The present invention relates to a vehicle seat provided with a seat cover (a surface material capable of generating heat for each area) divided into a plurality of areas.

In this type of vehicle seat, it is desirable that the seating surface of the seat can be appropriately heated in consideration of the seating ability of the occupant.
For example, the vehicle seat disclosed in Patent Document 1 includes a seat cushion, a seat cover, a plurality of heating elements (planar members), and a control unit.
The plurality of heating elements are arranged in parallel between the seat cover and the seat pad (arranged corresponding to each area of the present invention), and each part of the occupant (shoulder, back, waist) , Butt, thighs, etc.). Here, each heating element has, for example, a plurality of conductive yarns (yarn materials that can generate heat when energized) are arranged in parallel, and both ends of these conductive yarns are linear or belt-like connecting members (members that can be energized). ).
In the known technology, for example, by connecting a pair of wires extending from both ends (connecting members) of each heating element to the control unit, energization to each heating element is independently controlled by the control unit. Thus, it becomes the structure which contributes to the power-saving of a sheet | seat by setting it as the structure which can be heat-generated for every heat generating body (it is made to heat only a required part).

JP 2012-162207 A

In the known technique, each heating element includes an individual connection member and a pair of wirings. For this reason, the number of parts tends to increase because the number of connecting members and wires increases in proportion to the number of heating elements.
The present invention has been devised in view of the above points, and an object of the present invention is to enable the seat cover to generate heat for each area while suppressing an increase in the number of parts.

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 or a seat back. And a sheet | seat structural member has a seat cover provided with the electrically conductive thread which can be supplied with electricity, and a connection member which can be electrically connected with a part of conductive thread.
In the present invention, the seat cover is divided into a plurality of areas. Then, the connection member is attached to one side and the other side of the plurality of areas, and is electrically connected to the power supply unit via the wiring, so that the conductive yarn for each area can generate heat. In this type of configuration, it is desirable to allow the seat cover to generate heat for each area while suppressing an increase in the number of parts.

Therefore, in the present invention, as the connection member, a first connection member capable of traversing all of the plurality of areas and a plurality of second connection members capable of individually traversing each area are provided.
Then, the first connection member is electrically connected to the grounding portion of the power supply unit through a single wiring while being attached to one side of the plurality of areas so as to cross all of the first connection member. Further, each second connection member is electrically connected to the output part of the power supply part via an individual wiring while being attached to the other side of the corresponding one area.
In the present invention, since all of the plurality of areas (one side) can be electrically connected to the power supply unit via the first connection member and a single wiring, an increase in the number of parts can be suppressed as much as possible. And the other side of each area can be made to generate heat for every area by connecting to a power supply part with a separate 2nd connection member and wiring, respectively.

The vehicle seat of the second invention is the vehicle seat of the first invention, wherein the plurality of areas are formed by different skin-like skin pieces, and the end of at least one area has its end side inside. The folded inner part is used.
Therefore, in the present invention, the inner folding portion is a portion that does not require energization, and is disposed adjacent to another area. And it was set as the structure which the 1st connection member sews and attaches to both areas, crossing an inner folding part and another area.
In the present invention, when the first connecting member is attached, the conductive thread is sensed while being sensed, and the detection of the conductive thread at the inner folding portion (the part where no energization is required) can be omitted (the construction is excellent in workability). ).
Moreover, in this invention, the thickness dimension of an area becomes large in an inward folding part (it is a structure in which the heat | fever of a conductive yarn cannot be transmitted easily). Then, it becomes the structure which contributes to the power saving of a sheet | seat by making an inner folding part into a non-energized state (by making an inner folding part into a non-heating part).

A vehicle seat according to a third aspect is the vehicle seat according to the first aspect, wherein a plurality of areas are formed by different skin-like skin pieces, and an end of at least one area is adjacent to one area. It is arranged in a state of being overlaid on the end of another area that fits.
Therefore, in the present invention, a notch is provided on one side of at least one end of one area and another area. In the notch, the ends of both areas are made non-overlapping, and the first connecting member passes through the notch and crosses the end of one area and the end of the other area. The structure can be attached by suturing.
In the present invention, when the first connecting member is sewn to the end portions of both areas, the first connecting member can be sewn with good workability by reducing the thickness dimension at the same portion at the notch.

  According to the first aspect of the present invention, the seat cover can generate heat for each area while suppressing an increase in the number of parts. According to the second invention, the seat cover can generate heat with good performance for each area. According to the third aspect of the invention, the seat cover can generate heat with good performance for each area.

It is a cross-sectional view of a part of the seat cover. 10 is a longitudinal sectional view of a part of a seat cover according to Modification 1. FIG. FIG. 10 is a front view of a part of a seat cover in the middle of creation according to Modification 2. 10 is a front view of a part of a seat cover according to Modification 2. FIG.

Hereinafter, embodiments for carrying out the present invention will be described with reference to FIGS. In FIG. 1, 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 shown in FIG. 1 has a seat component (seat cushion 4, seat back 6, headrest 8). Each of these seat constituent members has a seat pad (4P, 6P, 8P) that forms the outer shape of the seat and a seat cover (4S, 6S, 8S) that covers the seat pad.

[Seatback]
The seat back 6 is a member that is connected to the seat cushion 4 in a tiltable manner, and has a main portion 6a and a pair of side portions 6b (see FIG. 1).
Here, the main portion 6a is a flat portion at the center of the seat back 6, and an occupant can be seated thereon. The pair of side portions 6b are convex portions on both sides of the seat back 6, and can support the side of the occupant during cornering of the vehicle.
In this embodiment, the seat cover 6S portion covering the main portion 6a is divided into a plurality of areas (first area AR1, second area AR2, third area AR3).
The first area AR1 is a part that forms the lower part of the main part 6a with the seat back standing up as a reference, and can face a part from the occupant's buttocks to the waist. Moreover, 2nd area AR2 is a site | part which makes the intermediate part of the main part 6a, and can face the site | part from a passenger | crew waist part to a back part. And 3rd area AR3 is a site | part which makes the upper part of the main part 6a, and can face the site | part from a passenger | crew's back part to a neck part.

In the present embodiment, as will be described later, each of the areas AR1 to AR3 is composed of a single piece of skin (a fabric that can be energized), and includes a conductive thread 11 that can be energized and another thread material 12 (FIG. 2). The details of each member will be described later as appropriate).
Corresponding connecting members (first connecting member 21 and plural second connecting members 22a to 22c) are appropriately attached to one side and the other side of the plurality of areas AR1 to AR3. And each connection member 21,22a-22c is electrically connected to a power supply part (illustration omitted) via corresponding wire harness (wiring) WH1-WH4, and can heat-generate the conductive yarn 11 for every area (for every area) Heat generation possible). In this type of configuration, it is desirable that the seat cover 6S can generate heat for each area while suppressing an increase in the number of parts.
Therefore, in this embodiment, the seat cover 6S can be heated for each area while suppressing an increase in the number of parts with the configuration described later. Hereinafter, each configuration will be described in detail.

[Conductive yarn]
The conductive yarn 11 is a conductive yarn material that can be energized, and typically has a specific resistance of 10 ⁰ to 10 ⁻¹² Ω · cm (in FIG. 2, for convenience, only a part of the conductive yarns 11 are ^{denoted by reference} numerals. Attached).
Here, the “specific resistance (volume resistivity)” is a physical property value used for comparing what kind of material is difficult to conduct electricity, and is measured in accordance with, for example, “JIS K-7194”. Can do. As this type of conductive yarn 11, a metal wire (for example, a conductive yarn material such as a metal or an alloy), a carbon fiber filament, a cover link yarn (a yarn material formed by covering another yarn material 12 described later with a metal wire or the like). ), A plated thread material (a thread material obtained by plating the surface of another thread material 12 with a metal or an alloy).

[Other thread materials]
The other thread material 12 is an insulating thread material (a thread material having a specific resistance larger than that of the conductive thread 11) (in FIG. 2, etc., for convenience, a part of the tissue portion formed of the other thread material is used. Reference numeral 12 is attached).
Examples of other yarn material 12 (material) of this type include plant-based and animal-based natural fibers, chemical fibers made of thermoplastic resin or thermosetting resin, and blended fibers thereof. As the other yarn material 12, the above-described yarn material (spun yarn, filament, drawn yarn or stretchable yarn (false twisted yarn or buckled yarn)) can be suitably used.

[Connecting member]
The first connecting member 21 and the second connecting members 22a to 22c are both planar members that can be energized, and are electrically connected to a part of the conductive yarn 11 (see FIGS. 2 to 4).
And the 1st connection member 21 is a comparatively long strip | belt-shaped member, The above-mentioned 1st area AR1, 2nd area AR2, and 3rd area AR3 are the up-down direction (direction orthogonal to the below-mentioned electrically conductive thread | yarn 11). It has a crossable length dimension.
Each of the second connecting members 22a to 22c is a relatively short band-shaped member, and has a length dimension capable of traversing only one of the corresponding areas (AR1, AR2, AR3). In the present embodiment, the second connection member 22a can cross the first area AR1. Another second connecting member 22b can cross the second area AR2, and yet another second connecting member 22c can cross the third area AR3.
In the present embodiment, the first connecting member 21 and the second connecting members 22a to 22c have substantially the same basic configuration, so the configuration will be described taking the first connecting member 21 as an example (see FIG. 2). .

The 1st connection member 21 of a present Example is provided with the 1st surface part 21a and the 2nd surface part 21b (refer FIG.3 and FIG.4).
The 1st surface part 21a is a surface material which has flexibility, for example, can be formed with the electrically conductive strip | belt body. Here, examples of the conductive band include a member having a flexible band-shaped support (fabric, fiber mat, resin sheet, etc.) and a metal conductor exposed from the support. Also, a plating layer can be provided on the surface of the support (along with or as a conductor).
The second surface portion 21b is a strip-shaped surface material that is substantially the same shape as the first surface portion 21a (separate from the first surface portion 21a before the stitching described later), and an insulating surface material (such as the above-described support). Or it can form with the same surface material as the 1st surface part 21a which can be supplied with electricity.

[Formation of each area]
In this embodiment, since the areas AR1, AR2 and AR3 have substantially the same basic configuration, the formation method will be described taking the first area AR1 as an example (see FIGS. 2 to 4).
In the present embodiment, a raw fabric (made of fabric) of the first area AR1 is created using the conductive yarn 11 and the other yarn material 12 as constituent yarns. At this time, the plurality of conductive yarns 11 are arranged in parallel at appropriate intervals from one side of the first area AR1 to the other side (in the sheet width direction).
When creating the first area AR1 of the woven fabric, after warping the warp yarn (other yarn material 12), when driving the weft yarn (other yarn material 12), the conductive yarn 11 is appropriately driven as a part of the weft yarn. Can do. Further, by using the conductive yarn 11 as a part of the warp, another yarn material 12 as a weft can be driven. When the first area AR1 of the knitted fabric is created, the conductive yarn 11 can be introduced into a part of the course direction or the wale direction. Further, when the first area AR1 of the nonwoven fabric is created, the base can be formed with the other yarn material 12, and the conductive yarn 11 can be arranged embedded in the base. In addition, the space | interval dimension of adjacent electrically conductive thread | yarn 11 can be suitably changed according to a sheet | seat structure. For example, when the first area AR1 is provided with a heater function, the distance between the conductive yarns 11 can be set within 60 mm.

Next, a part of the conductive yarn 11 is exposed from both ends of the first area AR1 (see FIG. 4). In the present embodiment, the other yarn material 12 is removed by melting or burning using, for example, a heating means (such as an optical heating means). At this time, by appropriately setting the temperature and output of the heating means, it is desirable to burn (melt) the other yarn material 12 without burning (melting) or breaking the main body of the conductive yarn 11 as much as possible.
Then, only the other yarn material 12 is melted (burned) by the heating means, and a pair of cuts are formed on both sides of the first area AR1. At this time, the other yarn material 12 is cut by the heating means, but the conductive yarn 11 remains as it is without being cut. Therefore, a part (end part) of the conductive yarn 11 can be exposed by peeling off the piece of cloth on the end side from the main body of the first area AR1.

[Formation of seat cover (formation of inner folding part)]
Each of the areas AR1 to AR3 thus created is stitched while being arranged in parallel above and below the seat to create a seat cover 6S (see FIG. 2).
In the present embodiment, the end portion of one area and the end portion of another area adjacent thereto are stitched and integrated. For example, referring to FIG. 3, after the end portion of the first area AR1 and the end portion of the second area AR2 are arranged facing each other, they are stitched together with a stitch line SEW3 in a middle surface.
At this time, in this embodiment, the inner folded portion 30 is formed by folding the end portion of the first area AR1 with the suture line SEW3. The inner folding part 30 has a thickness dimension larger than that of the other first area AR1, and is arranged adjacent to the second area AR2. In the present embodiment, the end of the second area AR2 is arranged so as to overlap the inner folding portion 30 (the overlapping portion 32 is formed).
In the present embodiment, the inner folding portion 30 and the overlapping portion 32 are set as portions (ARN) that do not require energization, and other area portions (portions other than the inner folding portion 30 and the overlapping portion 32) are portions that require energization ( ARE) (see FIG. 3).

[Installation work of connecting members]
Next, the connection members 21, 22a to 22c are electrically connected to a part of each conductive yarn 11 while being appropriately attached to the areas AR1 to AR3 (see FIGS. 2 to 4).
In the present embodiment, the first connecting member 21 is mounted on one side of a plurality of areas (AR1, AR2, AR3) while traversing all areas up and down (see FIG. 2).
At this time, referring to FIGS. 2 and 4, the first surface portion 21a and the second surface portion 21b are overlapped on one side of each of the areas AR1 to AR3, and the overlapped portion is sewn with a sewing machine (sewing line SEW1 Form). When using a sewing machine (not shown), the sensor device (not shown) detects in advance the conductive thread 11 arranged in front of the traveling direction D1 of the sewing needle of the sewing machine (see FIGS. 2 and 3). ). By doing so, the surface needles 21a and 21b can be sewn to the areas AR1 to AR3 while the sewing needle avoids the conductive thread 11. Then, after the first surface portion 21a and the second surface portion 21b are closed while sandwiching a part of each conductive yarn 11, the first connecting member 21 is formed by sewing them together (forming a suture line SEW2). .
By the way, on the end side (inner folding part 30, overlapping part 32) of each area, the thickness dimension becomes larger than other area parts (see FIGS. 3 and 4). For this reason, when the conductive yarn 11 is disposed in the inner folding portion 30 and the overlapping portion 32, it is difficult to detect the conductive yarn 11. Therefore, in this embodiment, both the inner folding portion 30 and the overlapping portion 32 are made portions that do not require energization, so that detection of the conductive yarn 11 in the same portion is omitted (while allowing breakage of the conductive yarn by the sewing needle). ), The first connection member 21 can be sewn across the end of each area (becomes excellent in workability).

Further, before and after the above-described operation, each of the second connection members 22a to 22c is attached to the other side of the corresponding one area AR1 to AR3.
In the present embodiment, the second connection member 22a (first surface portion, second surface portion) is disposed on the other side of the first area AR1 so as to cross vertically (see FIG. 2). Similarly, it arrange | positions so that another 2nd connection member 22b may be crossed on the other side of 2nd area AR2. And it arrange | positions on the other side of 3rd area AR3 so that another 2nd connection member 22c may be crossed.
Similarly, the corresponding second connecting members 22a to 22c are sewn to the other side of the areas AR1 to AR3 with a sewing machine (a suture line SEW1 is formed). Furthermore, the second connecting members 22a to 22c can be formed by stitching the first surface portions and the second surface portions (forming the suture line SEW2), respectively.
By the way, the edge part side (inner folding part 30, overlap part 32) of each area is a site | part which does not need electricity supply as above-mentioned, and the thickness dimension of each area becomes large (it is the structure which the heat | fever of a conductive yarn cannot transmit easily). . Therefore, in the present embodiment, for example, each of the second connection members 22a to 22c can be attached to the other side of the corresponding one area AR1 to AR3 while avoiding the inner folding part 30 and the overlapping part 32. By carrying out like this, it becomes the structure which contributes to the power-saving of a sheet | seat by making both the inner folding part 30 and the overlap part 32 into a non-energized state (it is set as a non-heating part).

Each area (skin piece of the main part 6a) created in this way is stitched to the skin piece on the side part 6b side to create the seat cover 6S (see FIG. 1).
Then, while the seat cover 6S is disposed on the seat pad 6P, the connecting members 21, 22a to 22c are electrically connected to a power supply unit (not shown) (see FIG. 2). At this time, in the present embodiment, the end of the first connection member 21 is electrically connected to the power supply unit (grounding unit) via the first wire harness WH1 (single wiring). Moreover, each 2nd connection member 22a-22c is electrically connected to a power supply part (output part which can supply electric power to a conductive thread | yarn) via each individual wire harness (WH2-WH4).
In this way, when only the first area AR1 is heated, the conductive yarn 11 in the first area AR1 is heated via the first connection member 21 and the second connection member 22a via a control mechanism (not shown). (See FIGS. 4 and 5). Similarly, when heat is generated in the second area AR2 (third area AR3), the conduction of the second area AR2 (third area AR3) via the first connection member 21 and the second connection member 22b (22c). Only the yarn 11 is heated.

As described above, in this embodiment, since all of the plurality of areas AR1 to AR3 (one side) are electrically connected to the power supply unit via the first connection member 21 and the single wire harness WH1, the number of parts is reduced. The increase can be suppressed as much as possible. And the other side of each area AR1-AR3 can be made to heat | fever for every area by connecting to a power supply part with each separate 2nd connection member 22a-22c and wire harness WH2-WH4.
Further, in the present embodiment, when the first connecting member 21 is attached, when the conductive yarn 11 is sewn while sensing, the detection of the conductive yarn 11 in the inner folding portion 30 (overlapping portion 32) can be omitted (workability). It becomes the composition which is excellent in).
And in a present Example, the thickness dimension of each area AR1-AR3 becomes large in the inner folding part 30 (overlapping part 32) (it is the structure which the heat | fever of a conductive yarn cannot transmit easily). Therefore, the inner folding part 30 (overlapping part 32) is in a non-energized state (by making it a non-heated part), thereby contributing to power saving of the sheet. And in a present Example, the site | part which does not need electricity supply can be set to a comparatively narrow range by making the inner folding part 30 and the overlap part 32 into the folded state.
Therefore, according to the present embodiment, the seat cover 6S can generate heat for each area while suppressing an increase in the number of parts.

[Modification]
Here, the configuration of each area can take various configurations in addition to the configuration described above. For example, in the present modification, when the seat cover 6S is created, the inner folded portion 30 is formed by folding one end side of the first area AR1 (the portion where the conductive yarn 11 is not disposed) with the suture line SEW3 (see FIG. 5). Similarly, the inner folded portion 30 is formed by folding the other end side of the second area AR2 along the suture line SEW3.
Even in such a case, it becomes difficult to detect the conductive yarn 11 by increasing the thickness dimension of the same portion at the inner folded portion 30 of each area. Even in this case, in the present modified example, each inner folding portion 30 is a portion (ARN) that does not require energization, so that detection of the conductive yarn 11 in the same portion can be omitted (becomes excellent in workability). .

Moreover, in the modification 2, the edge part of one area is arrange | positioned in the state overlaid on the edge part of the other area adjacent to it (refer FIG. 7).
For example, the end portion (upper end) of the first area AR1 is overlapped while entering the back of the end portion (lower end) of the second area AR2, and the thickness dimension of the overlapped portion is larger than the other portions. . Similarly, the end (upper end) of the second area AR2 is overlapped while entering the back of the end (lower end) of the third area AR3.
Therefore, in this modification, a notch 34 is provided on one end side of each of the areas AR1 to AR3 to form a substantially triangular space in front view (see FIG. 6). In this way, referring to FIG. 7, for example, even when the end portions of adjacent areas are overlaid, one end portion side of both areas is not overlapped in each notch portion 34 (the thickness dimension does not increase). Configuration).
Therefore, the first connecting member 21 is attached to both areas by sewing while passing over the notches 34 and crossing the end of one area and the end of the other area. As described above, in the present modification, when the first connecting member 21 is sewn to one end side of each of the areas AR1 to AR3, the thickness dimension of the end portion is reduced at each notch portion 34. One connecting member 21 can be sewn with good workability.
Further, on one side of the end of each area AR1 to AR3 (when there is no notch), these thickness dimensions are relatively large. Therefore, by providing a notch 34 on one end side of each of the areas AR1 to AR3 to suppress an increase in the thickness dimension, it is possible to avoid the first connecting member 21 from projecting more than necessary at the same portion. For this reason, it can avoid suitably that the 1st connection member 21 protrudes more than needed, abuts on another member, and is worn.

The manufacturing method of the cloth material of this embodiment is not limited to the above-described embodiment, and can take other various embodiments.
(1) In the present embodiment, the configuration (size, shape, number of formation, formation position, etc.) of each of the areas AR1 to AR3 is exemplified, but the configuration of each area is not limited. For example, at least one of the main part and the side part can be divided into a plurality of areas. In this embodiment, each area is divided in the sheet vertical direction, but can be divided in the sheet width direction. Further, the number of areas formed and the shape and dimensions thereof can be appropriately changed according to the sheet configuration.
(2) In the present embodiment, the example in which the inner folding part 30, the overlapping part 32, and the notch part 34 are appropriately provided at the end of each of the areas AR1 to AR3 has been described. They can be provided in appropriate combinations. Further, the inner folding part, the overlapping part, and the notch part can be provided in a plurality or a single area.
(3) Moreover, in this embodiment, as a structural example which makes the inner folding part 30 and the overlapping part 32 a non-energized state, each second connection member is made of one corresponding area while avoiding the inner folding part and the overlapping part. An example of mounting on the other side has been described. In contrast to this, the inner folding part (overlapping part) can be made into a non-energized state only by forming it with other thread material. Further, a part of the conductive yarn exposed from the inner folding portion (overlapping portion) can be removed. Depending on the sheet configuration, at least one of the inner folding part and the overlapping part is a part that needs to be energized, or a part that generates heat slightly weaker than a part that needs to be energized (a part where there are few electrofilaments that can be energized) You can also

(4) Moreover, in this embodiment, although the structure (shape, dimension, etc.) of each connection member 21,22a-22b was illustrated, it is not the meaning which limits the structure of the same member. For example, in the present Example, the 1st connection member 21 in which the 1st surface part 21a and the 2nd surface part 21b were separate bodies was illustrated. Unlike this, a first connecting member in which the first surface portion and the second surface portion are integrated in advance can be used. For example, the first surface portion and the second surface portion are arranged to face each other by folding the wide connecting member (one side is the first surface portion and the other side is the second surface portion) in two. The first connecting member may be formed only by the first surface portion. Each connecting member can also be formed of a linear member (such as a conducting wire).
(5) Moreover, although this embodiment demonstrated each area AR1-AR3 and the example which attaches each connection member by sewing, these members can be attached by methods, such as adhesion | attachment and welding. For example, when welding each area and the connecting member with an ultrasonic sewing machine, several centimeters of the running section are required so that the welding is stabilized. In the present embodiment, since the first connecting member is long, it has a configuration in which it is easy to take a run-up section, and the welding with each area is stable, so that problems do not easily occur.

(6) In the present embodiment, the example in which the plurality of conductive yarns 11 are linearly arranged in parallel in each area has been described. However, the configuration of the conductive yarns 11 is not limited. For example, the conductive yarns 11 can be arranged in parallel in each area in a wavy shape. Further, the exposed portion of the conductive yarn (connection portion with the connection member) is not limited to the end side and can be changed as appropriate.
(7) In the present embodiment, the wire harness is exemplified as an example of the wiring, but the configuration of the wiring is not limited. Various wires that can electrically connect each connection member and the power supply unit can be used as the wiring. The grounding unit and the output unit may be provided separately.
(8) In the present embodiment, the seat cover 6S of the seat cushion 4 has been described as an example. However, the configuration of the present embodiment can be applied to the seat cover 6S of various seat components such as a seat back. In addition to the vehicle seat, the configuration of this embodiment can be applied to all vehicle seats such as aircraft and trains.
