Description

Technical Field

[0001] This invention relates to an interior component for a vehicle, and more particularly to an interior component for a vehicle covered by a skin. Background Technology

[0002] Conventionally, interior vehicle parts such as door armrests include a base material and a skin material that coats the surface of the base material. The skin material may include, for example, a sheet-like soft material. The skin material is installed by rolling it into the outer periphery of the base material and applying an adhesive.

[0003] Patent document 1 discloses the following structure: multiple locking tabs are provided on the inner side of the core material, the peripheral end of the skin material is folded back at the end of the core material, and the locking hole formed at the end of the skin material is engaged with the locking tabs, thereby keeping the skin material in the core material.

[0004] However, when a sheet of soft material that is not injection molded is used as the skin to cover the substrate of an internal part, there are concerns that loose wrinkles or the ends of the skin material may detach from the retaining clips. Therefore, when fixing the skin material of the sheet of soft material to the substrate, adhesives are still used or a tacker is used to fix it at multiple points to roll in and fix the skin ends.

[0007] Patent Document 1: Japanese Patent Application Publication No. 2003-312346 Summary of the Invention

[0008] The problem that the invention aims to solve

[0009] If the method of fixing by rolling in adhesive is used, it involves more difficult work for the operator and is more time-consuming. In addition, since the process of applying adhesive is also included, it is difficult to reduce the time required. Therefore, the following structure is required: by eliminating adhesive or stopping the use of nailers or other means to roll in the skin end, the difficulty of manual work is reduced, and the skin material is easier to use for coating, thereby improving the work process and reducing the time required.

[0010] The present invention was made in view of the above-mentioned problems, and provides an interior part for a vehicle that improves workability and makes it easier to cover the skin onto the substrate, and reduces work steps or time.

[0011] Technical means to solve the problem

[0012] The above-mentioned problem is solved by the following: According to the present invention, an interior part for a vehicle is an interior part for a vehicle having a design surface, and includes a base material and a skin material covering the base material, the skin material having a linear locking member at the end of the skin material, the linear locking member being installed in the base material at a position not visible from the design surface side.

[0013] By incorporating linear retaining members at the ends of the skin material, the skin material is stretched by the lines, thus suppressing slack wrinkles when applied to the substrate. Furthermore, by installing the linear retaining members in a location not visible from the design side, such as the back side of the substrate, the skin material can be secured without the use of adhesives. Since no adhesives are used, this provides an improved and easier way to apply the skin material to the substrate for vehicle interior parts, reducing work steps and time. Because slack wrinkles are suppressed, deviations in the finished product result based on the operator are reduced, leading to improved and more stable appearance quality. Curving of design lines such as stitching on the skin material is also suppressed.

[0014] Additionally, in the aforementioned interior parts for vehicles, the linear locking member may be formed as a rod or a slender plate.

[0015] By designing the linear locking member into a simple structure, it can be easily engaged with the substrate. Furthermore, due to its simple structure, it can suppress the loosening and wrinkling of the skin material.

[0016] Additionally, the interior parts for the vehicle may include: a first linear locking member installed on a first terminal portion of the substrate, and a second linear locking member installed on a second terminal portion of the substrate located on the opposite side of the first terminal portion.

[0017] By installing linear locking members located on opposite sides, the skin material is stretched in opposite directions using the lines, thus further suppressing the loosening and wrinkling of the skin material.

[0018] Alternatively, in the above structure, the first linear locking member and the second linear locking member may be arranged in such a way that they move away from each other from the end of the substrate toward the center.

[0019] It can evenly hold the covering material in place according to the shape of the vehicle's interior parts, thereby suppressing loosening and wrinkling.

[0020] Alternatively, in the aforementioned interior parts for vehicles, the first linear locking member may be mounted on a first terminal portion located on the upper side of the substrate, and the second linear locking member may be mounted on a second terminal portion located on the lower side of the substrate, wherein the second linear locking member is longer than the first linear locking member.

[0021] By making the second linear locking member on the lower side longer than the first linear locking member, the covered skin material can be evenly locked, thereby suppressing the loosening and wrinkling of the skin material.

[0022] Additionally, in the aforementioned interior parts for vehicles, the first linear locking member may be mounted on a first terminal portion located on the upper side of the substrate, and the second linear locking member may be mounted on a second terminal portion located on the lower side of the substrate, with the outer skin material having a design line between the first linear locking member and the second linear locking member.

[0023] By installing a first linear locking component and a second linear locking component above and below the design line, the bending and skewing of the design line are suppressed, and the appearance and commercial appeal are improved.

[0024] Alternatively, in the aforementioned interior parts for vehicles, the base material may have a engaging portion on the back side of the terminal portion that engages with the linear locking member.

[0025] By having an engaging portion that engages with a linear locking member, loosening and wrinkling of the skin material covering the substrate can be suppressed.

[0026] Additionally, in the aforementioned interior parts for vehicles, the base material may have dotted locking portions outside the locking portion to lock the outer skin material.

[0027] By having dotted locking portions outside the locking portion, the loosening and wrinkling of the skin material covering the substrate can be further suppressed.

[0028] Additionally, in the aforementioned interior parts for vehicles, a through hole may be formed near the end of the outer skin material, and the engaging portion may have a hook portion that hooks onto the linear locking member, wherein the linear locking member is mounted to the substrate by hooking onto the hook portion inserted in the through hole.

[0029] By using the hooks inserted through the through holes to install the linear locking member onto the substrate, the loosening and wrinkling of the skin material covering the substrate can be further suppressed.

[0030] Alternatively, in the interior parts for the vehicle, the engaging portion may include a locking claw that engages the linear locking member, the linear locking member being formed as an elongated plate, and the linear locking member being mounted to the substrate by being disposed on the back side of the substrate and engaging with the locking claw.

[0031] By engaging the plate-shaped, linear locking member with the locking claw, locking can be easily achieved using a simple structure.

[0032] The effects of the invention

[0033] According to the present invention, by having a linear retaining member at the end of the skin material, the skin material is stretched by the line, thus suppressing slack wrinkles when covered with a substrate. Furthermore, by using the linear retaining member to install the skin end in a position not visible from the design side, such as the back side of the substrate, the skin material can be fixed without the use of adhesives. Since no adhesive is used, it provides a vehicle interior part that improves workability and makes covering the skin material with the substrate easier, while reducing work steps or time. Because slack wrinkles are suppressed, deviations in the finished product result based on the operator are reduced, leading to improved and stable appearance quality. Bending of design lines such as seams provided on the skin material is also suppressed.

[0034] Furthermore, by designing the linear locking member with a simple structure, it can be easily engaged with the substrate. Additionally, due to its simple structure, it can suppress the loosening and wrinkling of the skin material.

[0035] In addition, by installing linear locking members located on opposite sides, the skin material is stretched in opposite directions by the lines, thus further suppressing the loosening and wrinkling of the skin material.

[0036] In addition, the shape of the interior parts of the vehicle can be used to evenly hold the covering material in place, thereby suppressing loosening and wrinkling.

[0037] In addition, by making the second linear locking member on the lower side longer than the first linear locking member, the loosening and wrinkling of the skin material can be suppressed.

[0038] In addition, by installing a first linear locking member and a second linear locking member above and below the design line, the bending and skewing of the design line are suppressed, and the appearance and marketability are improved.

[0039] In addition, by having an engaging part, the loosening and wrinkling of the skin material covering the substrate can be suppressed.

[0040] In addition, the dotted locking portion can further suppress the loosening and wrinkling of the skin material covering the substrate.

[0041] In addition, by using the hook portion inserted in the through hole to install the linear locking member onto the substrate, the loosening and wrinkling of the skin material covering the substrate can be further suppressed.

[0042] In addition, by engaging the plate-shaped linear locking member with the locking claw, locking can be easily achieved using a simple structure. Attached Figure Description

[0074] <<First Implementation>>

[0075] Hereinafter, the structure of the interior parts for a vehicle according to the first embodiment of the present invention will be described with reference to the accompanying drawings. However, the embodiments described below are for the purpose of making the present invention easier to understand, and are not intended to limit the present invention. That is, the present invention can be modified and improved without departing from its spirit, and its equivalents are naturally included in the present invention.

[0076] Furthermore, in the following description, the content related to the material, shape, and size of interior parts for vehicles is merely one specific example and is not intended to limit the invention.

[0077] Furthermore, the following examples of interior parts for vehicles include door liners 50 and, in particular, handrails 1 installed in vehicle doors D, and their structural examples will be described. However, the present invention is not limited to door liners 50 installed on ground-moving vehicles with wheels, such as automobiles and railway vehicles, but can also be applied to interior parts installed on aircraft, ships, etc., which move in spaces other than the ground.

[0078] Furthermore, in the following explanation, "front and rear direction" refers to the front and rear direction of the vehicle's door D, and is the same direction as the vehicle's travel direction. That is, as shown below... Figure 1 As shown, the vehicle's direction of travel is designated as the front side, and its opposite side as the rear side. Furthermore, the term "vertical direction" refers to the vertical direction of the vehicle door D, and is the direction consistent with the vertical direction when the vehicle is traveling on a horizontal plane. Additionally, when simply referred to as "outer side," it refers to the direction from the center of the vehicle compartment where the vehicle door D is located outwards; when referred to as "inner side," it means the direction from the outer side of the vehicle towards the center of the vehicle compartment. The term "door width direction" is the same as the vehicle's width direction, and refers to the direction from the inner side of the vehicle door D outwards.

[0079] Furthermore, the shapes, positions, and orientations of the various parts of the vehicle door D and door lining 50 described below are assumed to be in a closed state, unless otherwise specified.

[0080] <Vehicle Doors>

[0081] Reference Figure 1 The basic structure of a vehicle door D, including the door liner 50 of the first embodiment, will be described. Figure 1 This is a side view showing the door lining 50 installed in the vehicle door D.

[0082] The vehicle door D includes a door panel P, a window W formed on the upper part of the door panel P, and a door liner 50 disposed in the door panel P below the window W. The door liner 50 includes an upper member 51, a central member 52, a lower member 53, and a handrail 1 protruding towards the vehicle interior between the central member 52 and the lower member 53. In addition, a door handle 54 is provided in front of the central member 52, and a door pocket 56 is provided in front of the lower member 53.

[0083] <Handrail>

[0084] Next, the handrail 1 of the door lining 50 will be described. The handrail 1 is an example of an interior part used in vehicles. Figure 2This is a side view of the armrest 1 taken from inside the vehicle. Figure 3 This is a cross-sectional view of handrail 1. (See diagram below.) Figure 2 and Figure 3 As shown, the armrest 1 is a component protruding towards the interior side and is a part for resting the hands or arms of an occupant seated in the vehicle. The armrest 1 has a shape extending along the front-rear direction of the vehicle door D, and an opening / closing switch 55 for operating the power window is provided on the upper surface of the armrest 1 (see reference). Figure 1 ).

[0085] The handrail 1 is installed on the central member 52 and the lower member 53, and has a design surface 2 that is visible to the occupants. Specifically, the design surface 2 is the surface that protrudes towards the interior side. Multiple bosses 3 are provided on the back of the handrail 1, which is not visible from the design surface side, so that it can be connected to the central member 52 and the lower member 53.

[0086] The handrail 1 has a base material 10 to maintain its protruding shape. Additionally, as... Figure 3 As shown, the handrail 1 has a skin material 20 that covers the surface 10a of the design surface 2 side of the substrate 10. The substrate 10 is made of resin, and the skin material 20 covering the substrate 10 is made of, for example, fabric, synthetic leather, or genuine leather. The skin material may also be made of non-woven fabric, film, etc. In addition, sometimes a pad Pa is provided between the substrate 10 and the skin material 20.

[0087] <Design Line>

[0088] The armrest 1 has an upper surface 1a for resting the occupant's hands or arms and a side surface 1b. At the boundary between the upper surface 1a and the side surface 1b, a seam 15, formed as a design line, is created on the outer material 20. At the intersection of the upper surface 1a and the side surface 1b, a cross portion 1e extending in the front-back direction is formed, such as... Figure 2 As shown, the stitch 15 is arranged in a straight line along the intersection 1e from the front end 1c of the handrail 1 to the rear end 1d.

[0089] In addition, such as Figure 3 As shown, the intersection 1e is formed as a flat, beveled surface. However, this is just one example; depending on the method of manufacturing the suture 15, the portion sewn to the back side of the outer skin material 20 may sometimes protrude. In this case, a recess extending along the intersection 1e can be formed, and the protruding portion of the suture 15 can be inserted into the recess. Alternatively, since the suture 15 is for design purposes, it may not be provided on the outer skin material 20.

[0090] Furthermore, regarding the design lines of this embodiment, a stitch 15 is provided as an accent line, but this is just one example. Patterns can also be printed on the surface of the outer material 20, or embossed patterns can be created by transfer printing.

[0091] <Linear locking component>

[0092] like Figures 3 to 4 As shown, at the upper end 21 of the skin material 20, a linear locking member 5 is provided in a linear shape corresponding to the shape of the upper end portion 11a and the upper end portion 11b of the substrate 10.

[0093] In this embodiment, a rod-shaped suspension cord 30 (first linear locking member) serving as a linear locking member 5 is provided at the upper end 21 of the outer skin material 20, through a nonwoven fabric 33. Furthermore, two suspension cords 30 are arranged along the upper end 21 of the outer skin material 20.

[0094] like Figure 3 and Figure 4 As shown, the cross-sectional shape of the suspension line 30 is a combination of a quadrilateral and a semicircle, but the cross-sectional shape of the suspension line 30 is not limited to this shape and can also be a quadrilateral or a circle.

[0095] In addition, such as Figure 3 and Figure 5 As shown, at the lower end 22 of the skin material 20, a linear locking member 5 is provided, which is also in the shape of the lower end portion 12a and the lower end portion 12b of the substrate 10.

[0096] In this embodiment, a trim cord 40 (second linear locking member), which is formed as an elongated plate, is sewn onto the lower end 22 of the outer skin material 20. The trim cord 40 is formed with the same cross-sectional shape in all parts. The trim cord 40 is arranged to extend along the lower end 22 of the outer skin material 20. Figure 2 and Figure 3 As shown, the adjustment line 40 is positioned opposite to the suspension line 30, in other words, it is positioned at the end (lower end 22) opposite to the suspension line 30.

[0097] In addition, a suspension line 30 may also be used as a linear locking member 5 installed on the lower end portion 12a and the lower end portion 12b.

[0098] The suspension line 30 and adjustment line 40, which are linear locking members 5, are installed on the surface material 20 at a position on the substrate 10 that is not visible from the designed side. Furthermore, in Figure 2In the diagram, to indicate the positions of the suspension line 30 and the adjustment line 40, they are shown as solid lines for convenience. However, if... Figure 3 As shown, the suspension line 30 and the adjustment line 40 are positioned in a location not visible from the design side, i.e., on the back side 10b of the substrate 10.

[0099] <Kahobu>

[0100] The following describes the engaging portion 6 provided on the substrate 10 for mounting the linear locking member 5 to the substrate 10, which engages with the linear locking member 5. In this embodiment, there are two types of engaging portions 6: the engaging portion 6 provided on the upper terminal portion 11a and the upper terminal portion 11b is designated as engaging portion 6A, and the engaging portion 6 provided on the lower terminal portion 12a and the lower terminal portion 12b is designated as engaging portion 6B.

[0101] like Figure 2 As shown, at a location not visible from the design side of the substrate 10, such as the upper end portion 11a and upper end portion 11b on the back side of the substrate 10, a plurality of engaging portions 6A are provided side by side to engage with the suspension line 30, which serves as a linear locking member 5.

[0102] like Figure 3 and Figure 4 As shown, the engaging part 6A that engages with the hanging line 30 is provided in the form of a hook part 31 that protrudes outward toward the outside of the door and has a barb part 31a at the top.

[0103] A through hole 34 is formed at the base of the suspension line 30 (non-woven fabric 33) for the hook part 31 to pass through. The hook part 31 is passed through the through hole 34 and the barb part 31a of the hook part 31 is hooked onto the suspension line 30, thereby the upper end 21 of the outer skin material 20 is installed at a position of the substrate 10 that is not visible from the design side (the end part of the back side).

[0104] Furthermore, the spacing between the hook portion 31 and the through hole 34 can be adjusted arbitrarily as appropriate.

[0105] On the lower end portion 12a and lower end portion 12b of the substrate 10, a plurality of engaging portions 6B are arranged to engage with the adjustment line 40, which serves as a linear locking member 5.

[0106] like Figure 3 and Figure 5As shown, the engaging portion 6B can also be provided in the form of a locking claw 41 supported by the boss 3. A barb portion 41a is provided on the locking claw 41. The adjusting line 40 is wound into the lower end portions 12a and 12b of the substrate 10 and inserted into the gap between the rib 46 and the barb portion 41a. The adjusting line 40 is fixed by hooking its side onto the barb portion 41a. Therefore, the adjusting line 40 is not easily detached from the locking claw 41. Furthermore, the gap between the rib 46 and the barb portion 41a of the locking claw 41 can be appropriately set to any size according to the specifications of the outer skin material 20.

[0107] Thus, by positioning the suspension line 30 and the adjustment line 40 in positions that engage with and face each other on the multiple engaging portions 6A and 6B provided on the substrate 10, the skin material 20 can be installed while the skin material 20 is stretched in the opposite direction using the lines.

[0108] In this embodiment, a total of four linear locking members 5 (top and bottom) are used to cover the skin material 20 and install it onto the substrate 10. However, the number of linear locking members 5 can be varied depending on the shape of the substrate 10. If the substrate 10 is a simple quadrilateral, one linear locking member 5 can be provided at the top and bottom of the skin material 20 for installation. For more complex shapes, the number of linear locking members 5 is matched to the number of sides of the substrate 10. It is not necessary to provide the same number of linear locking members 5 at the top and bottom; different numbers of linear locking members 5 can be used to install the skin material.

[0109] Thus, by attaching the skin material 20 to the substrate 10 using rod-shaped or elongated plate-shaped wire-like retaining members 5 at its ends, the skin material 20 can be stretched using the wires, suppressing loose wrinkles. Therefore, the skin material 20 can be attached to the substrate 10 without the use of adhesives. Since no adhesives are used, the workability of applying the skin material to the substrate is improved and made easier. As a result, the number of work steps or time can be reduced.

[0110] Since the outer skin material 20 is mounted to the substrate 10 without the use of adhesives, existing equipment that requires adhesives is no longer needed. For example, the coating booth, drying oven for drying adhesives, pressing die, stamping die, and fixtures used in adhesive-free coating can be reduced, thus minimizing equipment and workspace. The work process is simplified, the roll-up of the outer skin material 20 becomes easier, and work time can be reduced. Correction work can also be suppressed. Positional deviation and bending of the seam 15, which serves as the design line, are also suppressed, improving and stabilizing the finished appearance of the product. Since local elongation of the outer skin material can be suppressed, the unfolding rate of the outer skin material becomes generally uniform, processes such as leather squeezing can be suppressed, and the appearance and marketability can be improved.

[0111] <Configuration and length of linear locking components>

[0112] like Figure 2 As shown, the suspension line 30 and adjustment line 40, located on the front side of the armrest 1, correspond to the shape of the armrest 1 and are arranged such that the distance between the suspension line 30 and adjustment line 40 increases as they move from the front end 1c of the armrest 1 toward the center. That is, the suspension line 30 and adjustment line 40 are arranged in a U-shape.

[0113] In addition, the adjustment lines 40 arranged at the front and rear of the handrail 1 are arranged as follows: the extended overhead line EL1 extending from the adjustment line 40 on the front side and the extended overhead line EL2 extending from the adjustment line 40 on the rear side cross at the center of the handrail 1.

[0114] In addition, the suspension line 30 and adjustment line 40 located on the rear side are arranged in a U-shape such that the distance between the suspension line 30 and adjustment line 40 increases as it moves from the rear end 1d of the armrest 1 toward the center.

[0115] By configuring the suspension line 30 and the adjustment line 40 in this way, the covered skin material 20 can be evenly restrained to suppress loosening and wrinkling.

[0116] Alternatively, the distance between the suspension line 30 and the adjustment line 40 can be narrowed as they move towards the center from the front end 1c or the rear end 1d. In this case, the suspension line 30 and the adjustment line 40 are arranged to cross each other in the central part of the armrest 1.

[0117] Furthermore, the lengths L1a and L1b of the suspension line 30 installed on the upper terminal portion 11a and upper terminal portion 11b (first terminal portion) located on the upper side of the substrate 10 are longer than the lengths L1a and L1b of the suspension line 30. The lengths L2a and L2b of the adjustment line 40 installed on the lower terminal portion 12a and lower terminal portion 12b (second terminal portion) are longer.

[0118] By evenly locking the suspension line 30 and adjustment line 40 according to the shape of the armrest 1, loose wrinkles can be suppressed.

[0119] <The Relationship Between Design Lines and Surface Material>

[0120] As described above, a seam 15, serving as a design line, is formed on the surface of the outer skin material 20. The seam 15 is positioned between the drape line 30 and the adjustment line 40.

[0121] By providing a seam 15 between the suspension line 30, which serves as a linear locking member 5, and the adjustment line 40, bending and skewing of the seam 15 can be suppressed, thereby improving the appearance and marketability.

[0122] Alternatively, when covering the substrate 10 with the outer skin material 20, the stitch 15 can be positioned by using the upper end portion 11a, upper end portion 11b or lower end portion 12a, lower end portion 12b of the substrate 10 as a reference. Specifically, an adjustment line 40 is installed at the engaging portion 6B of the lower end portion 12a, lower end portion 12b to press the stitch 15 in the middle against the substrate 10, and a hanging line 30 is fixed at the engaging portion 6A (hook portion 31) of the upper end portion 11a, upper end portion 11b. Alternatively, a hanging line 30 can be installed at the engaging portion 6A of the upper end portion 11a, upper end portion 11b to press the stitch 15 in the middle against the substrate 10, and an adjustment line 40 is fixed at the engaging portion 6B of the lower end portion 12a, lower end portion 12b. This installation method allows for the suppression of bending and skewing of the suture 15.

[0123] <Point-shaped locking component>

[0124] In the handrail 1, in addition to the engaging portion 6 that engages with the linear locking member 5 formed by the suspension line 30 and the adjustment line 40, a dotted locking portion 4 is provided to lock the surface material 20. For example... Figure 2 As shown, the dotted locking portion 4 is disposed between the engaging portions 6 that engage the linear locking member 5, and engages portions of the outer skin material 20 that cannot be engaged by the linear locking member 5. For example, at the front end 1c of the handrail 1, the outer skin material 20 is installed by joining and covering, and the dotted locking portion 4 is used to secure it. Alternatively, it can be secured by hooking the end portion of the outer skin material 20.

[0125] <Another example 1 of a linear locking member>

[0126] Next, use Figure 6 Another example of the linear locking member 5 provided on the upper end portion 11a and upper end portion 11b of the substrate 10 will be described. Figure 6 The suspension line 30A described herein is a linear locking member 5 with a trapezoidal cross-sectional shape, connected to the upper end 21 of the outer skin material 20 through a non-woven fabric 33. The non-woven fabric 33 and the upper end 21 of the outer skin material 20 are joined by a sewing part 23.

[0127] At the upper end portion 11a and upper end portion 11b of the substrate 10, such as Figure 6 As shown, a retaining portion 32 with a recess 35 having an opening on the upper side is provided as an engaging portion 6A. By inserting the hanging wire 30A downward (in the direction of arrow C) into the recess 35, the retaining portion 32 engages with the hanging wire 30A, and the upper end 21 of the skin material 20 can be mounted to the substrate 10.

[0128] <Another example 2 of a linear locking component>

[0129] use Figures 7A to 8 Another example of the linear locking member 5 provided at the upper end portion 11a and the upper end portion 11b will be described. At the upper end portion 21 of the skin material 20, a thin, flat adjustment line 30B is installed as the linear locking member 5.

[0130] As the engaging part 6A, a hook part 31 is provided extending outward from the upper end part 11a and the upper end part 11b of the base material 10. On the other hand, as Figure 7B As shown, a through hole 34 for the hook portion 31 to pass through is formed near the upper end 21 of the outer skin material 20. Figure 7B As shown, a portion of the through hole 34 is positioned to overlap with the adjustment line 30B. Through the overlapping portion, such as... Figure 7A As shown, after the adjustment line 30B is installed, the upper side portion 30Bb of the adjustment line 30B rotates and moves to abut against the barb portion 31a, thereby becoming a slightly tilted state.

[0131] If using Figure 8 The installation sequence will be explained as follows: Figure 8 As shown in the upper section, the top end of the hook 31 is inserted into the through hole 34 of the outer skin material 20. When the upper end 21 is moved inward in the direction of arrow E, as... Figure 8 As shown in the middle section, the top of the hook 31 abuts against the upper side 30Bb of the adjusting line 30B, and the adjusting line 30B rotates and moves in the direction of arrow F. Although the adjusting line 30B rotates, it does not affect workability because the adjusting line 30B is extended.

[0132] like Figure 8 As shown in the lower section, when the adjustment line 30B is moved in the direction of arrow E, the hook portion 31 passes over the adjustment line 30B, and the upper side portion 30Bb of the adjustment line 30B abuts against the barb portion 31a. As a result, the adjustment line 30B is not easily dislodged from the hook portion 31, and is thus installed on the upper end portion 11b of the substrate 10.

[0133] <Another example of a linear locking component, 3>

[0134] Figure 8 The adjustment line 30B (linear locking member 5) shown is disposed on the outer side of the upper end 21 of the skin material 20, but it can also be disposed on the outer side as shown in the figure. Figure 9As shown, the adjustment line 30C is positioned inside the upper end portion 21. In this case, the adjustment line 30C is joined to the upper end portion 21 using the sewing part 23, and a through hole 34A is provided that passes through both the adjustment line 30C and the upper end portion 21. During installation, the hook part 31 extending from the upper end portion 11a and the upper end portion 11b of the substrate 10 is passed through to install it. By passing the hook part 31 through the through hole 34A that passes through both the adjustment line 30C and the outer skin material 20, the upper end portion 21 of the outer skin material 20 can be installed more securely.

[0135] In addition, such as Figure 10 As shown, the through hole 34 can also be formed only on the adjustment line 30C. Therefore, the yield is improved compared to the case where both are formed.

[0136] <Manufacturing Methods for Internal Components>

[0137] The following describes a method for manufacturing the armrest 1, an interior component of the vehicle door D in this embodiment.

[0138] Prepare a base material 10 for the handrail 1 with the design surface 2, and a skin material 20 for covering the base material 10 (step S01). At this time, a linear locking member 5 (suspending line 30 or adjusting line 40) is pre-installed at the ends (upper end 21 and lower end 22) of the skin material 20.

[0139] Next, the linear locking member 5 is installed in a position in the substrate 10 that is not visible from the design side (step S02). More specifically, the linear locking member 5 is engaged with the engaging portion 6 provided on the back side 10b of the substrate 10. Thus, the handrail 1 covered by the skin material 20 is completed.

[0140] When the outer skin material 20 is applied to the substrate 10, the following steps can be taken: after engaging the linear locking member 5 at one end with the engaging portion 6, the stitch 15, which serves as the design line, at the middle portion is pressed against the substrate 10, and the linear locking member 5 at the other end is fixed to the engaging portion 6. By fixing it in this way, loose wrinkles are suppressed, and bending or skewing of the stitch 15 is also suppressed, thereby improving the appearance and commercial appeal.

[0141] The above description, using the accompanying drawings, illustrates a handrail installed in the door lining of a vehicle as an interior component of this embodiment. However, the vehicle interior component is not limited to this and can be applied to various interior components. For example, it can also be applied to upper components, center components, lower components, pillars, dashboards, seat backs, etc., that are fitted with a cover material.

[0142] <<Second Implementation>>

[0143] Next, a second embodiment of the present invention will be described. The second embodiment relates to a vehicle seat, and more particularly to a vehicle seat including a cover that engages with a frame.

[0144] Conventionally, vehicle seats installed in automobiles and other means of transportation include a cover that covers a padding mounted on a frame and is fixed to the frame. Multiple hook pieces are sewn to the ends of the cover, and the cover is fixed by hooking the multiple hook pieces to the frame or the like (for example, see Japanese Patent Application Publication No. 11-206522).

[0145] However, the process of manually hooking multiple hooks one by one onto the predetermined parts of the frame is very labor-intensive and time-consuming. Therefore, a component that allows for easier installation of the seat cover onto the frame during the manufacture of vehicle seats is desired (first issue).

[0146] Furthermore, when using conventional methods to fix the padding-covered skin to the frame, the skin is forcefully fixed to the frame. Therefore, for example, when an occupant sits down, the skin follows the occupant's buttocks, exerting a peeling force on the connection between the skin and the frame. In the event of significant occupant movement, there is a possibility of damage to the connection. To reduce the force applied to the connection, a skin mounting component that shifts to some extent following the occupant's movements is desired (Second Problem).

[0147] In addition, after the hook is attached to the frame, the hook part of the hook or frame may sometimes be exposed and visible from the outside (third issue).

[0148] <The problem the invention aims to solve>

[0149] The second embodiment is based on the first problem described above, and its purpose is to provide a vehicle seat in which a cover covering the padding can be more easily installed onto the frame.

[0150] Furthermore, the second embodiment was developed in view of the second problem mentioned above, and its purpose is to provide a vehicle seat including a cover that can be displaced in accordance with the movements of a seated occupant.

[0151] Furthermore, the second embodiment is based on the third issue mentioned above, and its purpose is to provide a vehicle seat and a method for manufacturing a vehicle seat that do not expose the hook pieces or other engaging components even after the cover is installed on the pad.

[0152] <Technical means to solve the problem>

[0153] The aforementioned first problem is solved by the following: A vehicle seat according to the second embodiment includes a frame, a pad disposed on the frame, and a cover covering the pad. The cover has a frame engaging member at its end that engages with the frame. The frame engaging member has a plurality of engaging portions, and the frame is provided with a plurality of engaged portions corresponding to the plurality of engaging portions.

[0154] According to the second embodiment of the vehicle seat configured as described above, a plurality of engaging portions are formed in the frame engaging member that engages with the frame, so the frame engaging member can be installed together in the engaging portion formed on the frame. Therefore, unlike in the past, hook members are not installed one by one, and the cover can be installed on the frame more easily, improving workability when assembling the vehicle seat.

[0155] In the aforementioned vehicle seat, the plurality of engaging parts may each include an L-shaped hook integrally formed in the frame.

[0156] By using hooks that are L-shaped for the locking part, it is easy to engage the locking parts of the frame locking components with the locked part. Therefore, the skin can be installed on the frame more easily.

[0157] In the aforementioned vehicle seat, the frame engaging member may be a plate-shaped sheet metal member installed along the end of the skin.

[0158] By designing the frame locking components as plate-shaped sheet metal components, multiple locking parts can be installed together on the locked part of the frame, making it easier to install the skin onto the frame.

[0159] In the aforementioned vehicle seat, the plurality of engaging portions may each have an opening through which the engaging portion is inserted, and the openings are arranged in a manner along the end of the skin near the end of the plate member.

[0160] By forming an opening through which the locking part can be inserted, the locking part can be easily hooked in, making it easier to install the skin onto the frame.

[0161] In addition, in the aforementioned vehicle seat, the opening may be formed in a trapezoidal shape.

[0162] By forming the opening into a trapezoidal shape, the engaged portion is not easily disengaged from the opening.

[0163] In the aforementioned vehicle seats, the opening may be formed by an H-shaped or U-shaped slit.

[0164] The opening is formed by H-shaped or U-shaped slits, which can prevent dust or dirt from entering from the opening.

[0165] In the aforementioned vehicle seat, the opening may be formed by a cut in the sheet metal member and the end of the skin that seals the opening of the cut.

[0166] An opening can be easily formed by cutting open the sheet metal component and creating a cut at the end of the surface.

[0167] In the aforementioned vehicle seat, a reduced-diameter portion protruding toward the inside of the opening may be provided on the side of the opening.

[0168] By providing an inwardly protruding, tapered portion on the side of the opening, the engaged portion inserted into the opening is less likely to come out.

[0169] In the aforementioned vehicle seat, the length of the engaging edge that engages with the engaging portion in the opening may be greater than the length of the portion where the engaging portion engages with the engaging portion.

[0170] By making the length of the engaging edge in the opening greater than the length of the engaging portion of the engaged part, a margin is created in the offset width of the skin covering the padding. Even if the occupant moves their body while seated, the skin easily follows the body's movement. Therefore, damage to the skin is suppressed.

[0171] In the aforementioned vehicle seat, the frame engaging member may be a wire member installed along the end of the skin, and the portion of the wire member exposed through a cut formed at the end of the skin engages with the engaging portion disposed in the frame.

[0172] By setting the frame engaging component as a wire component, the frame engaging component can be easily formed.

[0173] The second problem is solved by the following: A vehicle seat according to a second embodiment includes a frame, a pad disposed on the frame, and a cover covering the pad. The cover has a frame engaging member at its end that engages with the frame. An engaging portion is formed in the frame engaging member. A engaged portion corresponding to the engaging portion is provided in the frame. The frame engaging member is a plate-shaped sheet member mounted along the end of the cover. The engaging portion has an opening through which the engaged portion passes. The length of the engaging edge in the opening that engages with the engaged portion is greater than the length of the portion of the engaged portion that engages with the engaging portion.

[0174] As described above, by making the length of the engaging edge in the opening greater than the length of the engaging portion of the engaged part, i.e., forming a gap in the opening, the skin covering the padding can be displaced. Even if the occupant moves their body while seated, the skin easily follows the body's movement, and damage to the skin is suppressed.

[0175] In the aforementioned vehicle seat, the engaging portion may include an L-shaped hook integrally formed in the frame.

[0176] By using hooks with an L-shaped locking part, the locking parts of the frame locking components can be easily locked with the locked part, making it easy to install the skin onto the frame.

[0177] In the aforementioned vehicle seat, a plurality of engaging portions are formed in the frame engaging member, and a plurality of engaged portions are provided in such a manner that they correspond to the plurality of engaging portions.

[0178] Since multiple engaging portions are formed in the frame engaging member that engages with the frame, the frame engaging members can be installed together on the engaging portion formed on the frame. In the past, hook members were installed one by one, but in this embodiment, they can be installed together, so the cover can be installed on the frame more easily, and the workability when assembling vehicle seats is improved.

[0179] In the aforementioned vehicle seat, the length of the engaging edge that engages with the engaging portion in the opening is 1.2 to 2.0 times the length of the portion of the engaging portion that engages with the engaging portion.

[0180] By setting the gap to be 1.2 to 2.0 times the size of the engaged part, the skin covering the pad is displaced more significantly, and damage to the skin is suppressed.

[0181] In the aforementioned vehicle seat, the opening may be formed in a trapezoidal shape.

[0182] By forming the opening into a trapezoidal shape, the engaged portion is not easily disengaged from the opening.

[0183] In the aforementioned vehicle seats, the opening is formed by an H-shaped or U-shaped slit.

[0184] The opening is formed by H-shaped or U-shaped slits, which can prevent dust or dirt from entering from the opening.

[0185] In the aforementioned vehicle seat, the opening may be formed by a cut in the frame engaging member and the end of the skin that seals the opening of the cut.

[0186] An opening can be easily formed by cutting open the sheet metal component and creating a cut at the end of the surface.

[0187] In the aforementioned vehicle seat, a reduced-diameter portion protruding toward the inside of the opening may be provided on the side of the opening.

[0188] By providing an inwardly protruding, tapered portion on the side of the opening, the engaged portion inserted into the opening is less likely to come out.

[0189] In the aforementioned vehicle seat, the opening may be an elongated hole extending along the end of the skin.

[0190] The opening is a narrow hole, making it difficult for the inserted part to come out.

[0191] In the aforementioned vehicle seat, the engaging portion may be inserted into the opening from the surface side of the frame engaging member, and in the state where the engaging portion is engaged with the engaging portion, the skin is folded back at the connection portion with the frame engaging member, so as to cover the engaging portion with the skin.

[0192] By using a skin to cover the locking part, the locking part is not exposed and therefore not visible from the outside, thus improving the design.

[0193] The aforementioned third problem is solved by the following: A vehicle seat according to the second embodiment includes a frame, a pad disposed on the frame, and a cover covering the pad. The cover has a frame engaging member at its end that engages with the frame. An engaging portion is formed in the frame engaging member. A locked portion corresponding to the engaging portion is provided in the frame. The locked portion engages from the surface side of the frame engaging member. In the state where the engaging portion engages with the locked portion, the cover is folded back at the connection portion with the frame engaging member to cover the locked portion.

[0194] Furthermore, the aforementioned third problem is solved by the following: the method for manufacturing a vehicle seat according to the second embodiment includes the following steps: preparing a frame, a pad, and a cover for covering the pad; arranging the pad on the frame and covering the pad with the cover; engaging a corresponding engaged portion of the frame engaging member that engages with the frame at the end of the cover from the surface side of the cover; and folding back the end of the cover at the connection portion with the frame engaging member to cover the engaged portion with the cover.

[0195] According to the second embodiment of the vehicle seat and its manufacturing method, with the engaging portion of the frame engaging member engaged with the engaged portion of the frame, the engaged portion is covered by a cover, thus preventing the engaged portion (e.g., a hook) from being exposed. Therefore, the engaged portion is not visible from the outside, improving the design of the vehicle seat.

[0196] In the aforementioned vehicle seat, the engaging portion may include an L-shaped hook integrally formed in the frame.

[0197] By using hooks that are L-shaped for the locking part, it is easy to engage the locking parts of the frame locking components with the locked part. Therefore, the skin can be installed on the frame more easily.

[0198] In the aforementioned vehicle seat, the frame engaging member may be a plate-shaped sheet metal member installed along the end of the skin, and the engaging portion has an opening through which the engaging portion is inserted.

[0199] By using frame-locking components as sheet metal components, a high-strength opening can be formed compared to the case where an opening is formed on the surface.

[0200] In the aforementioned vehicle seat, the length of the engaging edge that engages with the engaging portion in the opening may be greater than the length of the portion where the engaging portion engages with the engaging portion.

[0201] By making the length of the engaging edge in the opening greater than the length of the engaging portion of the engaged part, i.e., forming a gap in the opening, the skin covering the padding can be displaced. Even if the occupant moves their body while seated, the skin easily follows the body's movement, and damage to the skin is suppressed.

[0202] In the aforementioned vehicle seat, the opening may be formed in a trapezoidal shape.

[0203] By forming the opening into a trapezoidal shape, the engaged portion is not easily disengaged from the opening.

[0204] In the aforementioned vehicle seats, the opening may be formed by an H-shaped or U-shaped slit.

[0205] The opening is formed by H-shaped or U-shaped slits, which can prevent dust or dirt from entering from the opening.

[0206] In the aforementioned vehicle seat, the opening may be formed by a cut in the frame engaging member and the end of the skin that seals the opening of the cut.

[0207] An opening can be easily formed by cutting open the sheet metal component and creating a cut at the end of the surface.

[0208] In the aforementioned vehicle seat, a reduced-diameter portion protruding toward the inside of the opening may be provided on the side of the opening.

[0209] By providing an inwardly protruding, tapered portion on the side of the opening, the engaged portion inserted into the opening is less likely to come out.

[0210] In the aforementioned vehicle seat, the opening may be an elongated hole extending along the end of the skin.

[0211] The opening is a narrow hole, making it difficult for the inserted part to come out.

[0212] <The Effects of the Invention>

[0213] According to the second embodiment of the vehicle seat, multiple engaging portions are formed in the frame engaging member that engages with the frame, so that the engaging portions formed on the frame can be installed together. Therefore, unlike in the past, hook members are not installed one by one, and the cover can be installed on the frame more easily, improving the workability when assembling the vehicle seat.

[0214] Furthermore, by using L-shaped hooks for the locking parts, it is easy to engage the locking parts of the frame locking components with the locked parts. Therefore, the skin can be installed on the frame more easily.

[0215] In addition, by setting the frame locking component as a plate-shaped sheet metal component, multiple locking parts can be installed together on the locked part of the frame, making it easier to install the skin onto the frame.

[0216] In addition, by forming an opening through which the locking part can be inserted, the locking part can be easily hooked in, making it easier to install the skin onto the frame.

[0217] In addition, by forming the opening into a trapezoidal shape, the engaged portion is not easily disengaged from the opening.

[0218] In addition, the opening is formed by H-shaped or U-shaped slits, which can prevent dust or dirt from entering through the opening.

[0219] An opening can be easily formed by cutting open the sheet metal component and creating a cut at the end of the surface.

[0220] By providing an inwardly protruding, tapered portion on the side of the opening, the engaged portion inserted into the opening is less likely to come out.

[0221] Furthermore, by making the length of the engaging edge in the opening greater than the length of the engaging portion of the engaged part, a margin is created in the offset width of the skin covering the padding. Even if the occupant moves their body while seated, the skin easily follows the body's movement. Therefore, damage to the skin is suppressed.

[0222] In addition, by setting the frame engaging member as a wire member, the frame engaging member can be easily formed.

[0223] Furthermore, in the vehicle seat according to the second embodiment, by making the length of the engaging edge in the opening greater than the length of the engaging portion of the engaged part, i.e., forming a gap in the opening, the surface covering the padding can be displaced. Even if the occupant moves their body while seated, the surface easily follows the body's movement, and damage to the surface is suppressed.

[0224] In addition, by using hooks with an L-shaped locking part, it is easy to engage each locking part of the frame locking component with the locked part, and the skin can be easily installed on the frame.

[0225] Furthermore, since multiple engaging portions are formed in the frame engaging member that engages with the frame, the frame engaging members can be installed together on the engaging portion formed on the frame. Previously, hook members were installed one by one, but in this embodiment they can be installed together, thus simplifying the installation of the cover onto the frame and improving workability when assembling vehicle seats.

[0226] In addition, by setting the gap to be 1.2 to 2.0 times the size of the engaged part, the skin covering the pad is displaced more significantly, and damage to the skin is suppressed.

[0227] In addition, by forming the opening into a trapezoidal shape, the engaged portion is not easily disengaged from the opening.

[0228] In addition, the opening is formed by H-shaped or U-shaped slits, which can prevent dust or dirt from entering through the opening.

[0229] Alternatively, openings can be easily formed by cutting open the sheet metal components and creating a cut at the end of the surface.

[0230] In addition, by providing an inwardly protruding narrowed portion on the side of the opening, the locked portion inserted into the opening is less likely to come out.

[0231] In addition, because the opening is formed by a narrow hole, the engaged part inserted into the opening is not easy to come out.

[0232] In addition, by using a skin to cover the locking part, the locking part will not be exposed and therefore will not be visible from the outside, thus improving the design.

[0233] Furthermore, according to the second embodiment of the vehicle seat and its manufacturing method, when the engaging portion of the frame engaging member is engaged with the engaged portion of the frame, the engaged portion is covered with a cover, so the engaged portion (e.g., a hook) is not exposed. Therefore, the engaged portion is not visible from the outside, improving the design of the vehicle seat.

[0234] Furthermore, by using L-shaped hooks for the locking portion, it is easy to engage the locking portions of the frame locking components with the locked portion. Therefore, the skin can be installed onto the frame more easily.

[0235] In addition, by using frame-clamping components as sheet metal components, a high-strength opening can be formed compared to the case where an opening is formed on the surface.

[0236] Furthermore, by making the length of the engaging edge in the opening greater than the length of the engaging portion of the engaged part, i.e., forming a gap in the opening, the skin covering the padding can shift. Even if the occupant moves their body while seated, the skin easily follows the body's movement, and damage to the skin is suppressed.

[0237] In addition, by forming the opening into a trapezoidal shape, the engaged portion is not easily disengaged from the opening.

[0238] In addition, the opening is formed by H-shaped or U-shaped slits, which can prevent dust or dirt from entering through the opening.

[0239] Alternatively, openings can be easily formed by cutting open the sheet metal components and creating a cut at the end of the surface.

[0240] In addition, by providing an inwardly protruding narrowed portion on the side of the opening, the locked portion inserted into the opening is less likely to come out.

[0241] In addition, because the opening is a narrow hole, the engaged part inserted into the opening is not easy to come out.

[0242] <Detailed Implementation>

[0243] Hereinafter, the structure of a vehicle seat according to the second embodiment (this embodiment) of the present invention will be described with reference to the accompanying drawings. However, the embodiment described below is an example to facilitate understanding of the present invention and is not intended to limit the present invention. That is, the present invention can be modified and improved without departing from its spirit, and its equivalents are naturally included in the present invention.

[0244] Furthermore, the following describes a vehicle seat as an example of a seat for transportation, and its structural example will be explained. However, the present invention is not limited to vehicle seats mounted on ground-moving vehicles with wheels, such as automobiles and railway vehicles, but may also be used on seats mounted on aircraft, ships, and other vehicles that move in space other than the ground.

[0245] Furthermore, in the following explanation, "front-to-back direction" refers to the front-to-back direction of the vehicle seat, which is the same as the direction of travel when the vehicle is in motion. "Seat width direction" refers to the width direction of the vehicle seat, which is the same as the left-to-right direction as observed from the seated occupant. "Up-down direction" refers to the up-down direction of the vehicle seat, which is the same as the vertical direction when the vehicle is traveling on a horizontal plane.

[0246] In addition, in the following description, when “seat” is added to various directions such as “seat width direction” or “seat height direction”, it indicates the direction relative to the vehicle seat; when “vehicle” is added to “vehicle interior” or “vehicle exterior”, it indicates the direction relative to the vehicle.

[0247] Furthermore, the shapes, positions, and postures of the various parts of the vehicle seats described below are assumed to be in the seated position as described later, unless otherwise specified.

[0248] <Basic Structure of Vehicle Seats>

[0249] Reference Figure 11 and Figure 12 The basic structure of the vehicle seat (hereinafter referred to as vehicle seat S) of this embodiment will be described. Figure 11 This is a 3D diagram of a vehicle seat (S). Figure 11 In the illustration, for the sake of clarity, a portion of the vehicle seat S is shown with the structure after the trim cover 117 and trim cover 127, which serve as the outer cover, are removed.

[0250] The vehicle seat S is a seat placed on the vehicle floor for vehicle occupants to sit on. In this embodiment, the vehicle seat S is used as a front seat, which corresponds to the front seats of the vehicle. However, it is not limited to this; the vehicle seat S can also be a rear seat of the vehicle. In addition, in a vehicle that includes three rows of seats in the front-rear direction, it can also be used as the middle seat of the second row or the rear seat of the third row.

[0251] like Figure 11As shown, the main components of the vehicle seat S are: a seat cushion S1, which serves as the seating portion supporting the buttocks of the occupant; a seat back S2, which serves as the backrest portion supporting the occupant's back; and a headrest S3, which is disposed on the upper part of the seat back S2 and supports the occupant's head. The seat cushion S1 and the seat back S2 are sandwiched by a tilting mechanism 160 (see reference). Figure 12 Furthermore, although not shown in the figure, a slide rail is provided at the lower part of the seat cushion S1, and the vehicle seat S is placed on the vehicle floor in a state in which it can slide and move in the front and rear directions using the slide rail.

[0252] In the vehicle seat S, there is a Figure 12 The frame F shown mainly includes a cushioning frame 101 and a backrest frame 102. The cushioning frame 101 forms the skeleton of the seat cushioning pad S1 in the frame F, and the backrest frame 102 forms the skeleton of the seat backrest S2 in the frame F.

[0253] The rear end of the seat cushion S1 is connected to the lower end of the seat backrest S2. The seat cushion S1 is constructed by attaching a cushion pad 116 to the cushion frame 101 and then covering the cushion pad 116 with a decorative sleeve 117. The seat backrest S2 is constructed by attaching a backrest pad 126 to the backrest frame 102 and then covering the backrest pad 126 with a decorative sleeve 127.

[0254] The cushioning pad 116 and the backing pad 126 are, for example, urethane substrates formed by foaming using an urethane foaming agent. The cushioning pad 116 and the backing pad 126 correspond to the pads of the second embodiment. Furthermore, the decorative sleeve 117 for the cushioning pad and the decorative sleeve 127 for the back correspond to the outer skin of the second embodiment, and are made of cloth, film, fabric, leather, or sheet material. The decorative sleeves 117 and 127 are installed such that they cover the cushioning pad 116 and the backing pad 126 while being stretched to apply a predetermined tension.

[0255] In this embodiment, when the decorative sleeve 117 for the cushioning pad covers the cushioning pad liner 116, the end of the decorative sleeve 117 is installed at a predetermined position. The installation method will be described later.

[0256] like Figure 12 As shown, the cushioning frame 101 of frame F has a roughly square frame shape. Moreover, the main components of the cushioning frame 101 are: a pair of cushioning side frames 112, which respectively form the left and right ends in the width direction of the seat; a pan frame 111, which forms the front end of the cushioning frame 101; and a spring 114 (S-type spring).

[0257] To define the width of the buffer pad frame 101, the two buffer pad side frames 112 are arranged to be separated in the left-right direction and extend in the front-rear direction of the vehicle. Furthermore, a front tube 113a connecting the two buffer pad side frames 112 is installed at the front end, and a rear tube 113b is installed at the rear end.

[0258] The disc frame 111 is fixedly joined to the front side of a pair of buffer pad side frames 112, and the left and right buffer pad side frames 112 are connected at the front side by means of the disc frame 111. More specifically, the left and right ends of the disc frame 111 are fixed to the flanges provided on the buffer pad side frames 112 by means of welding or other fixing methods.

[0259] The disc frame 111 is mainly used to support the thighs of the seated person (occupant) and is a frame containing a metal plate, the upper surface of which is formed into a generally flat, roughly rectangular shape.

[0260] Between the left and right cushion side frames 112, a plurality of springs 114 (S-shaped springs) are arranged side by side as pressure-bearing parts in the seat width direction. The springs 114 extend long in the front-rear direction of the seat. The front end of the spring 114 is fixed to the front tube 113a, and the rear end of the spring 114 is locked to the rear tube 113b. In addition, a pressure plate 114a is provided on the spring 114.

[0261] <Being Carded Section>

[0262] On the lower surface of the disc frame 111, a plurality of hooks 115a (engaged portions) for mounting the ends of the decorative sleeve 117 are formed. The hooks 115a are L-shaped in cross section and are provided by chiseling open a portion of the disc frame 111.

[0263] On the left and right side frames 112, multiple hooks 115b (engaged parts) for mounting the ends of the decorative sleeves 117 are also formed. Figure 12 As shown, the cross-section of hook 115b is formed in an inverted L shape, and it is provided by chiseling open a part of the cushioning pad side frame 112.

[0264] On the lower surface of the pressure plate 114a, similar to the buffer pad side frame 112 and the disc frame 111, a plurality of hooks 115c (engaged portions) for mounting the ends of the decorative sleeve 117 are formed. The hooks 115c have an L-shaped cross-section and are provided by chiseling open a portion of the pressure plate 114a. Furthermore, in the following description, unless it is necessary to specifically distinguish between the hooks 115a to 115c provided on the buffer pad side frame 112, the disc frame 111, and the pressure plate 114a, they are sometimes simply referred to as hooks 115.

[0265] <Back Frame>

[0266] The back frame 102 mainly comprises tubes processed into a square frame shape, such as... Figure 12 As shown, the back frame 102 includes: an inverted U-shaped upper frame 121; a pair of back side frames 122 forming the left and right ends in the width direction of the seat; and a lower frame 123 connecting the lower ends of the pair of back side frames 122.

[0267] Additionally, a pressure plate 124 is provided on the backrest frame 102, which is suspended from the backrest frame 102. A suspension frame 125 for suspending the pressure plate 124 is provided across the left and right backrest side frames 122. A cylindrical headrest guide 121a is installed at the upper center of the backrest frame 102. The headrest S3 is installed on the seat backrest S2 by inserting a headrest column 161 extending from the lower end of the headrest S3 into the headrest guide 121a.

[0268] Materials used to construct the components of the buffer frame 101 and the back frame 102 include those with sufficient rigidity to prevent significant deformation under load, such as steel or aluminum alloys. The components of the buffer frame 101 and the back frame 102 are joined together by welding, but may also be joined using screws or adhesives.

[0269] <Decorative Cover for Cushion Pads>

[0270] Next, refer to Figures 13 to 16 The structure of the decorative cover 117 for the cushioning pad will be described. The decorative cover 117 is a component that covers the cushioning pad liner 116 of the seat cushioning pad S1, and has a cover body 117a and an extension 117b.

[0271] The main body 117a covers the upper surface, front surface, and both sides of the cushioning pad 116. For example... Figure 14 As shown, the extension 117b is the portion that extends from the rear end of the sleeve body 117a, and as... Figure 16 As shown, the surface covers the protrusion 116a that protrudes rearward from the cushion pad 116. Furthermore, the protrusion 116a of the cushion pad 116 is the portion that inserts into the gap V between the seat back S2 and the rear tube 113b of the cushion frame 101.

[0272] <Frame engagement components>

[0273] At the end of the decorative sleeve 117, a frame engaging member 118 is provided that engages with the hook 115 (engaged part) provided on the buffer pad frame 101.

[0274] Furthermore, a plurality of engaging portions 119 are formed in the frame engaging member 118. In the cushioning frame 101, a plurality of hooks 115, which are the engaging portions of this invention, are provided corresponding to the positions where the engaging portions 119 are located. Alternatively, the plurality of engaging portions 119 may be formed in the frame engaging member 118 in a manner corresponding to the positions on the cushioning frame 101.

[0275] like Figure 13 and Figure 14 As shown, the frame engaging member 118 is a plate-shaped material member installed along the end of the sleeve body 117a of the decorative sleeve 117. The frame engaging member 118 is installed at the end of the sleeve body 117a by sewing. The frame engaging member 118 is also installed at the top of the extension 117b of the decorative sleeve 117 by sewing.

[0276] The plate-shaped frame engaging member 118 is formed of a rigid synthetic resin, such as polypropylene resin or vinyl chloride resin. The frame engaging member 118 may also be made of metal such as iron or aluminum. In addition, the thickness of the frame engaging member 118 is preferably 1 mm to 8 mm, more preferably 1.5 mm to 5 mm.

[0277] The frame engaging member 118 is installed on the sleeve body 117a of the decorative sleeve 117 by sewing, but it can also be joined by adhesive.

[0278] Furthermore, in the frame engaging member 118, the top portion that engages with the hook 115 can also be made thicker than the other portions. By thickening the top portion, the strength is increased, and breakage is suppressed.

[0279] In this embodiment, such as Figure 14 and Figure 17A As shown, each engaging portion 119 of the frame engaging member 118 is provided with a through opening 130. The width L2 of the lower edge 130b of the opening 130 that engages with the hook 115 is formed to be approximately the same size as the width L1 of the hook 115.

[0280] During assembly, for example, after the cushioning pad liner 116 is placed on the cushioning pad frame 101, the decorative sleeve 117 is covered, and the frame engaging member 118 located in front of the cushioning pad is hooked onto the hook 115a of the disc frame 111. Then, as... Figure 15 As shown, the frame engaging member 118 is hooked onto the hook 115b of the buffer pad side frame 112.

[0281] Regarding the extension 117b of the decorative sleeve 117, as Figure 16As shown, the protrusion 116a of the cushioning pad 116 is inserted into the gap V, then the extension 117b is folded back, and the frame engaging member 118 provided at the end of the extension 117b is installed on the hook 115c of the pressure plate 114a of the frame F.

[0282] Thus, the decorative sleeve 117 is installed on the cushioning frame 101. In the past, multiple hooks 115 were installed one by one using J hooks or the like, but in this embodiment, multiple hooks 115 are hooked at once using a frame engaging member 118 with multiple engaging parts 119, so the decorative sleeve 117 can be easily installed on the frame F.

[0283] <Shape of the locking part>

[0284] use Figures 17A to 19F The shape of the opening 130 formed in the engaging portion 119 will be described.

[0285] like Figure 17A As shown, each engaging portion 119 of the frame engaging member 118 has an opening 130 formed in the form of a transversely elongated through hole. If explained based on the direction shown in the figure, the lengths of the upper edge 130a and the lower edge 130b (engaging edges) of the opening 130 are approximately the same as the length L2 in the width direction of the hook 115. The two sides of the engaging portion 119 are formed in a curved manner. Therefore, it has a shape that slightly bulges out in the center in the vertical direction, allowing the hook 115 to be easily inserted. Furthermore, depending on the location where the hook 115 is positioned (e.g., hook 115a of the disc frame 111), the upper edge 130a becomes the front edge, and the lower edge 130b becomes the rear edge.

[0286] <Another example from the Kahe tribe>

[0287] exist Figure 18A and Figure 18B The image shows another example of an opening 130, namely an opening 130A. Figure 18A The opening 130A shown is also a through hole formed laterally in each engaging portion 119 of the frame engaging member 118. If explained based on the direction shown in the figure, in the opening 130A, the length L2 of the upper side 130Aa is approximately the same as the length L1 in the width direction of the hook 115. On the other hand, the length L3 of the engaging edge (lower side 130Ab) on the lower side for direct hooking of the hook 115 is formed to be greater than the length L1 of the engaging portion of the hook 115. In other words, the opening 130A is formed as a trapezoidal shape that partially protrudes in the direction along the end of the decorative sleeve 117 (arrow A direction). A portion known as a clearance is formed because the lower side 130Ab of the opening is greater than the length L1 in the width direction of the hook 115. Figure 18AAs shown, a clearance portion is formed in either of the parts where the hook 115 engages. Clearance portions may also be provided on both sides. Having clearance portions provides the following effect.

[0288] When the occupant sits on the seat cushion S1, as Figure 17B As shown, sometimes the decorative sleeve 117 will be stretched upwards following the occupant's hips. (As...) Figure 17A As shown, when the opening 130 for inserting the hook 115 is formed without providing a clearance portion, even under tension, the displacement C1 of the frame engaging member 118 is small, and the decorative sleeve 117 will not shift significantly. Therefore, if a stronger force is applied to the decorative sleeve 117, there is a possibility that the connection portion 131 between the decorative sleeve 117 and the frame engaging member 118 may break.

[0289] If so Figure 18A As shown in the diagram, the opening 130A has a clearance portion, then... Figure 18B As shown, when the decorative sleeve 117 is stretched upwards, the decorative sleeve 117 and the frame engaging member 118... Figure 17B The displacement is more significant compared to the situation shown. Because the displacement C2 is large, the force applied to the connection portion 131 between the decorative sleeve 117 and the frame engaging member 118 is reduced, thus suppressing breakage. The length L3 of the engaging edge, including the clearance portion, is set according to the desired displacement C2, but is preferably about 1.2 to 2.0 times the length L1 in the width direction of the hook 115, more preferably about 1.5 times.

[0290] <Example of a modified opening>

[0291] use Figures 19A to 19F A modified example of the opening 130 formed in the engaging portion 119 will be described. Figure 19A The opening 130C shown is formed by an H-shaped slit 132. The tongue 133 formed by the slit 132 is flexed by inserting a hook 115, which can be inserted into and engaged in the opening 130C.

[0292] in addition, Figure 19B The opening 130D shown is formed by a U-shaped slit 132A.

[0293] Figure 19C The middle shows along Figure 19B The cross-section of line AA. By inserting hook 115 into opening 130D, as... Figure 19CAs shown, the tongue 133A flexes, and the hook 115 engages with the opening 133D. By forming a through hole using a slit, as in the opening 130C or opening 130D, the hook 115 is not easily dislodged, and the intrusion of dust or dirt from the opening 130C or opening 130D can be suppressed.

[0294] Figure 19D The opening 130E formed therein is formed by the cut 134 formed in the frame engaging member 118 and the end of the decorative sleeve 117. The opening of the cut 134 is sealed by the end of the decorative sleeve 117. In this way, as long as a part that can be inserted into the hook 115 is formed in the opening 130E, the engaging part can be formed more easily.

[0295] In addition, such as Figure 19E As shown, the opening 130F can also be formed by an elongated hole 135 extending along the end of the decorative sleeve 117. The hook 115 inserted into the elongated hole 135 is not easily dislodged because its vertical movement is suppressed.

[0296] In addition, such as Figure 19F As shown, a reduced diameter portion 136 protruding into the inside of the opening 130G can also be provided on both sides of the opening 130G. The reduced diameter portion 136 is formed slightly lower than the center of the opening 130G in the vertical direction, in other words, closer to the lower edge 130Gb where the hook 115 is hung.

[0297] A wide portion (wide portion 137) and a narrow portion (narrow portion 138) are formed in the opening 130G. A hook 115 is inserted into the wide portion 137 and the hook 115 passes over the narrow portion 136 and enters the narrow portion 138, thereby realizing an opening 130G in which the hook 115 is not easy to detach.

[0298] <Installation method of frame interlocking components>

[0299] use Figure 20A and Figure 20B The method of installing the frame engaging member 118 onto the hook 115a is described. Figure 20A and Figure 20B It is along Figure 12 A cross-sectional view of the XX-XX line.

[0300] Figure 20A The figure shows a method of installing the hook 115a by inserting it into the opening 130 from the back side 117d of the decorative sleeve 117 (more specifically, the back side 118b of the frame engaging member 118).

[0301] like Figure 20AAs shown, when the hook 115a is inserted into the opening 130 from the back side 117d of the decorative sleeve 117, the hook 115a will be exposed. Although the frame engaging member 18 is easy to install, there is a problem that the hook 115a can be observed from the outside.

[0302] Therefore, in Figure 20B In the installation method shown, the hook 115a is covered by the decorative sleeve 117 so that the hook 115a is not exposed to the outside. The hook 115a is inserted into the opening 130 from the surface side 117c of the decorative sleeve 117 (more specifically, the surface side 118a of the frame engaging member 118). With the hook 115a (the engaged part) engaged with the engaging part 119, the decorative sleeve 117 is folded back to the opposite side at the connection part 131 with the frame engaging member 118. By folding the decorative sleeve 117 back, as... Figure 20B As shown, the decorative sleeve 117 covers the hook 115a.

[0303] use Figure 21 , for those containing Figure 20B The manufacturing method of a vehicle seat S will be described using the installation method of the frame engaging member 118 shown. (Preparation) Figure 12 The frame F shown has a backrest pad 126 disposed on it, and is equipped with a back cover 127 to cover the backrest pad 126. Then, the cushion pad 116 and the cover 117 constituting the seat cushion S1 are prepared (step S101).

[0304] A cushioning pad 116 is provided on the frame F, and the cushioning pad 116 is covered by a decorative sleeve 117 (step S102).

[0305] Then, the hook 115a provided on the frame F is inserted from the surface side 118a (surface side of the skin) of the frame engaging member 118 into the engaging part 119 (more specifically, the opening 130) of the frame engaging member 118 provided at the end of the decorative sleeve 117, so that the engaging part 119 engages with the hook 115 (step S103).

[0306] After engaging the hook 115a with the engaging part 119, the end of the decorative sleeve 117 is folded back at the connection part 131 with the frame engaging member 118, so that the decorative sleeve 117 covers the hook 115 (step S104).

[0307] By applying a predetermined tension by hooking the frame engaging member 118 onto the hook 115a, the decorative sleeve 117 is installed onto the cushioning pad 116.

[0308] In addition, by installing the frame engaging member 118 onto the hook 115a in this way, the hook 115 is not exposed and therefore not visible from the outside, thus improving the design of the vehicle seat S.

[0309] Furthermore, the above installation method uses hook 115a as an example, but the same method can also be used to install the decorative sleeve 117 for hooks 115b and 115c.

[0310] <Another example of frame locking components>

[0311] exist Figure 14 The end of the decorative sleeve 117 for the cushioning pad shown is fitted with a plate-shaped material member as a frame engaging member 118. The frame engaging member 118 is not limited to a plate shape; for example, it can also be... Figure 22 As shown in the frame engaging member 118A, it is implemented by a linear wire member 139. The wire member 139 is installed along the end of the decorative sleeve 117.

[0312] The wire component 139 is stored through a pocket-shaped space formed by folding back and sewing the end of the decorative sleeve 117. Furthermore, a portion of the decorative sleeve 117 is cut open, exposing a portion of the wire component 139 to form a locking part 119A. The exposed wire component 139 (locking part 119A) is hooked onto the hook 115. By applying a predetermined tension, the decorative sleeve 117 for the cushioning pad is secured to the cushioning pad liner 116.

[0313] The wire component 139 is preferably made of metal or resin in the form of a rod, wire, or tube. Furthermore, the diameter of the wire component 139 is preferably 1 mm to 8 mm, more preferably 1.5 mm to 5 mm.

[0314] The second embodiment of a vehicle seat and its manufacturing method have been described above using the accompanying drawings. In the above embodiment, the decorative sleeve 117 for the seat cushion S1 was used as an example, but this is only one example; the invention can also be applied to the seat back S2. That is, a frame engaging member can be provided on the decorative sleeve 127 for the back pad that covers the back pad 126 on the seat back S2 for installation. Since the corresponding engaging parts can be installed together on the multiple hooks provided on the back frame 102, the workability of assembling the back pad 126 is improved.

[0315] The second embodiment disclosed above is further described below.
