Description

  The present invention has a base material that forms an outer shape of a vehicle interior product and the like, and a planar skin that covers the outer surface of the base material, and the end portion of the skin turns from the edge of the outer surface of the base material to the back surface. It is related with the fixing structure of the epidermis which is made into the state where it was set and was fixed to the back surface with the fastener.

  A vehicle interior such as a vehicle seat has a base material that forms the outer shape of the vehicle interior product, and a planar skin that covers the outer surface of the base material. And when covering the base material on the base material, the skin is applied to the outer surface of the base material, the end side of the skin is folded back toward the back surface of the base material at the edge of the outer surface of the base material, and the fastener is further attached. Via the back. In this way, the end portion of the skin covering the outer surface of the base material is brought into a state of wrapping around from the edge portion of the outer surface of the base material to the back surface, and is fixed to the back surface by the fastener.

  For example, the vehicle seat disclosed in Patent Document 1 includes a seat cushion as a base material, a side surface of the seat cushion corresponding to the outer surface of the base material, and a skin covering the side surface. And the corner area | region notched so that it may form a substantially semicircle shape is provided in the edge part of the side part lower part of a seat cushion. Moreover, the edge part of the skin part which covers a corner area | region is divided | segmented into the some division | segmentation piece part by the some triangular cut. Each of the plurality of divided piece portions has a substantially trapezoidal shape having the same shape and the same size, and the adjacent divided piece portions are gradually separated from each other toward the ends. Therefore, the side surface of the seat cushion is covered with a skin, and the end of the skin is folded back to the back side at the edge that forms the corner region. When arranging the skin along the corner area, the surplus length (peripheral length difference) of the skin with respect to the corner area is absorbed by bringing the adjacent divided pieces close to each other and filling the space between them. And by fixing each division | segmentation piece part to a back surface with a fastener, respectively, the edge part side of an outer skin can be arrange | positioned neatly along the curved shape of a corner area | region.

  Here, in the known technique, the circumferential length difference between the corner region of the base material and the end portion of the skin covering the base region is absorbed by filling between the adjacent divided pieces. However, in the configuration of the known technique, the end lengths of the adjacent divided pieces are sufficiently separated so that the surplus length can be absorbed. However, the base sides of the adjacent divided pieces are close to each other, so that the surplus length is sufficient. It was in a state that could not be absorbed. For this reason, when the corner area is covered with the edge of the epidermis, the surplus length generated on the base side of the split piece part causes the skin part (relatively soft part) between the split piece parts to bend excessively and rise. There was a possibility of deteriorating the designability. However, it is also possible to avoid the excess length from being concentrated on a specific skin portion by reducing the number of divided pieces and increasing the number of formations. However, this increases the number of fasteners to be used, increases the manufacturing cost of vehicle interiors, and makes the work of fixing the edge of the skin extremely cumbersome. The present invention has been devised in view of the above-mentioned points, and the problem to be solved by the present invention is that the end of the skin disposed in the corner region of the base material is based on a relatively simple configuration.

Further, in this covering state, the end portion 20E of the left skin 20 is moved from the front edge end portion 14c and the upper edge end portion 14a of the left shield portion 14 shown in FIG. 2 to the back surface 14IS side of the left shield portion 14 shown in FIG. You can wrap around.

[Divided piece]
At least a part of the end portion 20E of the left skin 20 is provided with a plurality of cuts 30 and a plurality of split piece portions 32a to 32g with reference to FIG. Common reference numeral 30 is attached). That is, in the present embodiment, the end portion 20E of the left skin 20 disposed at the front edge end portion 14c forming the corner area CA is divided into a plurality of divided piece portions 32a to 32g by a plurality of cuts 30. The plurality of cuts 30 are portions formed by cutting the end portion 20E of the left skin 20 into a triangular shape, and are provided so that the bottom side is disposed on the terminal side of the end portion 20E. And the notch 30 is provided in the edge part 20E of the left skin 20 at equal intervals along the direction where the front edge edge part 14c extends, and the edge part 20E of the left skin 20 is divided | segmented into several division | segmentation piece parts 32a-32g. It is divided into. The plurality of divided piece portions 32a to 32g are small piece portions having substantially the same shape and the same size, and are arranged at equal intervals along the direction in which the front edge end portion 14c extends. For example, referring to FIG. 6, the split piece portion 32b disposed on the lower side of the end portion 20E of the left skin 20 has a substantially trapezoidal shape having a narrow upper base on the end 32E side. The width dimension is gradually increased toward the opposite base 32B side (length dimension LX of the split piece portion on the base side). And in the time of the covering operation | work of the left-sided skin 20 mentioned later, with reference to FIG. 7, it moves to the direction which adjoins the division | segmentation piece parts mutually (in the direction of the thick black arrow D1 of FIG. 7), and between these It will be packed and arranged.

[Penetration part]
And the penetration part 40 and the other penetration part 42 are formed in each division | segmentation piece part 32a-32g, respectively. Here, since the penetration part 40 and the other penetration part 42 are formed with substantially the same basic configuration in each of the divided piece parts 32a to 32g, the divided piece part 32b shown in FIG. The details of 40 and other through portions 42 will be described. That is, the penetrating portion 40 of the split piece portion 32b is a linear cut extending along the front edge portion 14c forming the corner area CA with reference to the state in which the left skin 20 is covered with the base material 10. . Here, the penetrating portion 40 extends along the front edge end portion 14c, in addition to the case where the penetrating portion 40 extends in parallel with the front edge end portion 14c, and the direction in which the front edge end portion 14c extends. It means that the through portion 40 extends in substantially the same direction. For example, in the present embodiment, the front edge portion 14c extends while curving gradually toward the upper side. In such a case, when the penetrating portion 40 extends linearly, curvedly, or flexibly gradually rearward as it goes upward, the penetrating portion 40 penetrates in substantially the same direction as the direction in which the front edge end portion 14c extends. This corresponds to the case where the portion 40 extends. The penetrating portion 40 can be formed by partially cutting the divided piece portion 32b with a physical means such as a blade, and there is no need to remove a part of the divided piece portion 32b like a notch. Since the surface area of the divided piece portion 32b is suitably maintained by forming the through portion 40 at the cut line, it is possible to avoid the strength of the divided piece portion 32b from being excessively reduced. And the penetration part 40 is arrange | positioned at the base 32B side instead of the terminal end 32E side of the division | segmentation piece part 32b, and is arrange | positioned adjacent to the skin part 21 between the division | segmentation piece parts 32b mentioned later. And the division | segmentation piece part 32b is made easy to shrink | contract in the direction where the corner area | region CA extends (in the direction of the thick white arrow D2 of FIG. 7) by providing the penetration part 40. FIG. The penetrating portion 40 can be disposed at a portion on the base 32B side where the divided piece portion 32b is appropriately contracted. For example, the divided piece portion 32b is divided into three or more equal parts in the direction from the end 32E toward the root 32B (preferably six In the case of dividing into equal parts or more), it can be arranged within the range of the portion closest to the root 32B. And this penetration part 40 is provided irrespective of the fastener 50 mentioned later, for example, is provided in the position different from the location which attaches the fastener 50, or is provided prior to attachment of the fastener 50.

  Furthermore, in the present embodiment, when the divided piece portion 32b is divided into approximately equal parts in the vertical direction, the divided piece portion 32b can be easily contracted substantially uniformly above and below. That is, with reference to FIG. 6, a virtual straight line IL extending in the direction orthogonal to the extending direction of the corner area CA and equally dividing the through portion 40 is assumed in the divided piece portion 32 b. At this time, in the divided piece portion 32b, the dimension L1 of the through hole portion extending upward from the virtual straight line IL and the dimension L2 of the through hole portion extending downward from the virtual straight line IL are set to be substantially the same. Therefore, by dividing the segment piece 32b into a line-symmetric trapezoidal shape with the imaginary straight line IL as the symmetric axis, the upper piece portion 31a arranged above the imaginary straight line IL and the lower side arranged below the imaginary straight line IL. The one part 31b can be easily contracted substantially uniformly. The upper piece portion 31a corresponds to a divided piece portion disposed on one side of the virtual straight line of the present invention, and the lower piece portion 31b is disposed on the other side of the virtual straight line opposite to the one side. It corresponds to the part. It should be noted that the line-symmetric-shaped divided piece portion 32b has a difference in shape between the upper-side piece portion 31a and the lower-side piece portion 31b within the range of allowable errors in addition to the case where it is completely line-symmetrical. It is also included.

[Other penetrations]
Further, referring to FIG. 6, the other penetrating portion 42 is a linear cut extending in a direction intersecting with the penetrating portion 40, and can be formed by partially cutting the divided piece portion 32 b. The other penetration part 42 of the present embodiment is provided at a position overlapping the virtual straight line IL, and extends in a direction orthogonal to the penetration part 40. The other penetrating portion 42 is connected to the penetrating portion 40 at the tip on the base 32B side, and extends toward the end 32E of the split piece portion 32b. For this reason, in the divided piece portion 32b, the upper piece portion 31a and the lower piece portion 31b are divided by the other penetrating portion 42 in the portion from the penetrating portion 40 to the end 32E side. For this reason, the divided upper side part 31a and lower side part 31b are in a state in which they can move toward each other (in the direction of the thick white arrow D3 in FIG. 7), with the other penetration part 42 interposed therebetween. Arranged vertically.

[Covering of the skin to the substrate (fixing the edge of the skin)]
Referring to FIG. 3, the outer surfaces of the corresponding shield portions 14 and 16 are respectively covered by the left skin 20 and the right skin 22. Here, since the covering method of the left skin 20 and the right skin 22 is substantially the same, the covering method will be described taking the left skin 20 as an example. That is, referring to FIGS. 2 and 4, the left skin 20 is applied to the outer surface of the left shield part 14, and the end part 20 </ b> E side of the left shield 20 is placed from the front edge part 14 c of the left shield part 14 to the upper edge part. Fold it inward on the back side at the part over 14a. And as shown in FIG. 4, the edge part 20E of the left side skin 20 is fixed to the back surface 14IS of the left side shield part 14 with the fastener 50. As shown in FIG.

  And in the above-mentioned work, since it is necessary to arrange the end 20E side of the left skin 20 along the front edge 14c as the corner area CA, the extra length of the left skin 20 with respect to the corner area CA is on the end 20E side. Need to absorb. Therefore, in the present embodiment, as shown in FIG. 5, the end portion 20 </ b> E of the left skin 20 disposed in the corner area CA is divided into a plurality of divided piece portions 32 a to 32 g by a plurality of cuts 30. Then, referring to FIG. 7, in order to absorb the extra length of left skin 20 on the end 20E side, the adjacent divided pieces are moved toward each other (in the direction of thick black arrow D1 in FIG. 7). Between them. In this type of configuration, there is a possibility that the skin portion 21 between the adjacent divided piece portions 32b will rise excessively due to the extra length generated on the base 32B side of each divided piece portion 32a to 32g. That is, when the divided pieces 32a to 32g are hard and difficult to shrink, the extra length is concentrated on the relatively soft skin portion 21 described above.

  Therefore, in the present embodiment, each of the plurality of divided piece portions 32a to 32g shown in FIG. 5 is easily contracted in the extending direction of the corner area CA by providing the through portions 40, and It is fixed to the back surface with a fastener 50. For example, the segment piece 32b shown in FIGS. 6 and 7 is easily shrunk in the direction in which the corner area CA extends (in the direction of the thick white arrow D2 in FIG. 7) by the linear through portion 40 provided on the base 32B side. Has been. For this reason, referring to FIG. 7, the surplus length of left skin 20 generated on the root 32B side of divided piece 32b can be absorbed by the shrinkage of divided piece 32b (the divided piece on the root side after shrinkage). Length dimension LY (LY <LX)). At this time, by dividing the segment piece 32b into a line-symmetric trapezoidal shape with the imaginary straight line IL shown in FIG. 6 as the axis of symmetry, the upper segment 31a and the lower segment 31b can be contracted almost equally in a well-balanced manner. Can do. Furthermore, in the present embodiment, the plurality of split piece portions 32a to 32g shown in FIG. That is, referring to FIG. 6, for example, in the divided piece portion 32 b, the upper piece portion 31 a and the lower piece portion 31 b are divided by another penetrating portion 42. Therefore, when the divided piece portion 32b is contracted, the divided upper piece portion 31a and lower piece portion 31b are moved toward each other as shown in FIG. 7 (in the direction of the thick white arrow D3 in FIG. 7). By doing so, the division | segmentation piece part 32b will shrink | contract smoothly. At this time, by connecting the penetrating portion 40 and the other penetrating portion 42, the upper piece portion 31a and the lower piece portion 31b can move more smoothly in the direction approaching each other while overlapping in the thickness direction.

  By absorbing the extra length generated on the base 32B side of each of the divided piece portions 32a to 32g in this way by the shrinkage of each divided piece portion 32a to 32g, it is as much as possible that excessive excess length is concentrated on the specific skin portion 21 as much as possible. It can be avoided. Then, as shown in FIG. 5, each of the split pieces 32a to 32g is fixed to the back surface 14IS of the left shield part 14 with the clip 50, so that the left skin 20 is arranged cleanly following the curvature of the corner area CA. I can keep it. At this time, in this embodiment, since it is not necessary to excessively increase the number of divided pieces formed, it is possible to suitably avoid that workability at the time of fixing by the fastener 50 is excessively deteriorated. Further, by fixing the right skin 22 to the back surface of the right shield part 16 by the same method, the right skin 22 can be neatly arranged following the curvature of the corner area CA. In addition, in a present Example, although a part of fastener 50 penetrates division piece part 32a-32g, a penetration part may arise in division piece part 32a-32g, but the said penetration part is a penetration part of this invention. Or it does not correspond to other penetration parts.

  As described above, in the present embodiment, the plurality of divided piece portions 32 a to 32 g are each easily contracted in the extending direction of the corner area CA at the through portion 40. And since the surplus length of each skin 20, 22 is absorbed by the shrinkage of each divided piece portion 32a to 32g, without excessively increasing the number of formation of each divided piece portion 32a to 32g, between the adjacent divided piece portions. It is possible to avoid as much as possible that the extra lengths of the skins 20 and 22 are concentrated on the skin part 21 to be arranged. In this embodiment, each of the divided piece portions 32a to 32g can be easily contracted in an appropriate direction by the linear through portion 40 extending along the corner area CA. At this time, by forming the through portion 40 at the cut line, it is possible to avoid the strength of each of the divided piece portions 32a to 32g from being excessively reduced. Furthermore, by bringing the penetration portion 40 close to the skin portion 21 arranged between the adjacent divided piece portions and shrinking the divided piece portions 32a to 32g at appropriate portions, each skin 20, Concentration of 22 extra lengths can be avoided more reliably.

  Further, in this embodiment, the divided piece portions 32a to 32g can be more easily contracted more smoothly by the linear through portion 40 and the other linear through portion 42. At this time, by connecting the penetrating portion 40 and the other penetrating portion 42, each of the divided piece portions 32a to 32g can be more easily contracted. Further, in the present embodiment, when a virtual straight line IL extending in a direction orthogonal to the direction in which the corner area CA extends and equally dividing the through portion 40 is assumed, a split piece portion portion disposed on one side of the virtual straight line IL ( The upper piece part 31a) and the divided piece part (lower piece part 31b) arranged on the other side of the virtual straight line IL opposite to the one side are easily shrunk equally. By carrying out like this, each division | segmentation piece part 32a-32g can be made easy to shrink with sufficient balance by the linear penetration part 40. FIG. Therefore, according to the present embodiment, the end portions 20E and 22E of the respective skins 20 and 22 arranged in the corner area CA of the base material 10 are designed on the back surface 14IS and the like of the base material 10 with a relatively simple configuration. It can be fixed well.

  The vehicle seat of the present embodiment is not limited to the above-described embodiment, and can take other various embodiments. In the present embodiment, the configuration (shape, dimension, formation position, number of formation, etc.) of each of the divided piece portions 32a to 32g is illustrated, but the configuration of the divided piece portions is not intended to be limited. For example, two or more divided pieces can be provided at the end of the skin in accordance with the shape and length of the corner region, and the shape (outer dimensions) of each divided piece is also independently polygonal or Various shapes such as a semicircular shape can be used. Moreover, the structure of a notch can be suitably changed according to the structure of the division | segmentation piece part which should be formed. In addition, a division | segmentation piece part can also be provided in the edge part of the skin arrange | positioned at the edge part (this embodiment upper edge part) which does not comprise a corner part.

  Moreover, in this embodiment, although the structure (a shape, a dimension, a formation position, the number of formation etc.) of the penetration part 40 and the other penetration part 42 was illustrated, it is not the meaning which limits the structure of these each penetration part. For example, at least one of the penetrating part and the other penetrating part can be configured by a through hole formed by removing a part of the divided piece part. Further, at least one of the divided pieces can be provided with another through portion. For example, the other through portion is formed only in the divided piece portion arranged at the portion where the extra length of the skin is the largest, and the other divided portions are formed. Other penetrating parts can be omitted in one part. The other penetrating portions are not necessarily formed on a virtual straight line, can be provided independently without being connected to the penetrating portions, and can be omitted as necessary. Moreover, a plurality of penetrating parts and other penetrating parts are appropriately combined to form an external shape similar to a specific character such as a cross-shaped C-shape, E-shape, Z-shape, L-shape or H-shape, A graphic unrelated to a specific character can be formed. In addition to the case where the plurality of through portions and the other through portions are formed linearly, the plurality of through portions may be curved in a wave shape, or may be bent in a crank shape or a zigzag shape.

  Further, in the present embodiment, the configuration in which the segment piece 32b is contracted in a balanced manner has been described as a line-symmetric trapezoidal shape with the virtual straight line IL as the symmetry axis. In this configuration, only the base side of the divided piece portion can have a line-symmetric shape with the virtual straight line as the axis of symmetry. For example, when the penetrating portion is divided into three or more equal parts in the direction from the end toward the root, the penetrating portion is disposed within the range of the portion closest to the root. And only the part nearest to the root of this division piece part is made into the line symmetrical shape which used the virtual straight line as the symmetry axis, and thereby the division piece part can be shrunk with good balance. In addition, when the through part is configured by a long hole-like through hole, the surface area of the divided piece part excluding the through part on one side of the virtual straight line and the surface area of the divided piece part excluding the through part on the other side of the virtual straight line are approximately Even by setting them to the same value, the divided pieces can be shrunk in a well-balanced manner.

  Further, in the present embodiment, the configuration of the present embodiment is applied to the vehicle seat 2 as a vehicle interior product, but the configuration of the present embodiment can be applied to a member having a base material and a skin, and is particularly arranged in a vehicle interior. The present invention can be suitably applied to a vehicle interior product or an interior product (for example, a home interior product) arranged in a house.
