Summary of the Invention

Problems to be Solved by the Invention

[0004] However, the box-shaped protector provided in the side door part of Patent Document 1 has a structure that maintains rigidity, and improvement in energy absorption performance has been desired.

[0005] Therefore, the present invention has been made in view of the above problems, and an object thereof is to provide an interior part for a vehicle provided with a lightweight and compact shock-absorbing member while improving the energy absorption efficiency during a side collision.

Means for Solving the Problems

[0006] The above problem is solved by the vehicle interior component of the present invention, which comprises a door panel, a door trim attached to the door panel, an impact absorbing member disposed between the door panel and the door trim and attached to one of the door panel or the door trim, and another member attached to one of the door panel or the door trim, wherein the impact absorbing member has a first recess formed in the longitudinal direction of the vehicle, the other member has a fixing portion for attaching the other member to one of the door panel or the door trim, and the fixing portion for the other member is the first recess A location surrounded by This is resolved by placing it in that location.

[0007] In the vehicle interior component of the present invention configured as described above, the vehicle interior component can be arranged compactly.

[0008] Furthermore, the impact absorbing member has a bottom surface on which a fixing portion is formed to be attached to one of the door panel or the door trim, an opposing surface facing the other of the door panel or the door trim, a front surface positioned forward, a rear surface positioned backward, an upper surface positioned above, and a lower surface positioned below, between the opposing surface and the bottom surface, wherein the opposing surface, the front surface and the bottom surface form a U-shaped cross-section, and preferably the bottom of the first recess corresponds to the front surface or the rear surface. With the above configuration, a U-shaped cross-section is formed by the opposing surface, front surface, and bottom surface, making it possible to properly receive loads and absorb impacts.

[0009] Furthermore, it is preferable that the fixing portion is provided only on either the front or rear side of the bottom of the first recess in the vehicle's longitudinal direction.

[0010] Furthermore, it is preferable that the fixing portion for the other member is positioned in the vehicle's longitudinal direction on the side opposite to the side of the bottom of the first recess where the fixing portion is positioned. With the above configuration, interference between the fixing portion of the shock-absorbing member and the fixing portions of other members can be suppressed.

[0011] Furthermore, the impact-absorbing member is preferably provided with a plurality of reinforcing ribs, and the bottom of the first recess is preferably positioned between the plurality of reinforcing ribs. According to the above configuration, the first recess separates and arranges multiple reinforcing ribs, making it possible to obtain sufficient rigidity in a compact space.

[0012] Furthermore, the bottom surface of the impact-absorbing member is provided with a second recess that is recessed in the direction toward the opposing surface, and it is preferable that a part of the first recess is positioned at the same height as the first second recess in the vertical direction of the vehicle. With the above configuration, the second recess on the bottom surface and the first recess on the front or rear surface intersect at least partially, thereby improving the rigidity of the connection between the fixed bottom surface and the front or rear surface.

[0013] Furthermore, it is preferable that a plurality of reinforcing ribs are provided on the opposing surface of the impact-absorbing member. With the above configuration, the formation of reinforcing ribs on the opposing surfaces makes it possible to effectively absorb impacts.

[0014] Furthermore, it is preferable that the multiple reinforcing ribs provided on the opposing surfaces are arranged to surround the opposing surfaces in the vertical direction and in the front direction.

[0015] Furthermore, it is preferable that the multiple reinforcing ribs provided on the opposing surfaces are inclined to move inward as they are directed from the front to the rear. [Effects of the Invention]

[0017] According to the vehicle interior part of the present invention, since the shock absorption member is attached to one of the door panel or door trim in a cantilever form, it is possible to gently slow down the initial rise of the load stress applied to the opposing surface during a side impact. Also, according to the vehicle interior part of the present invention, since the shock absorption member has an inverted L-shaped shape in a top view and a bottom view, it is possible to appropriately absorb the shock applied to the shock absorption member during a side impact while reducing the weight of the shock absorption member. Also, according to the vehicle interior part of the present invention, since the opposing surface that serves as the contact surface against the shock is inclined, it is possible to bring one end of the opposing surface into contact first. Also, according to the vehicle interior part of the present invention, the rigidity of the fixing part is improved by forming the fixing part to protrude, and the fixing to the door panel or door trim is stabilized. Also, according to the vehicle interior part of the present invention, since a U-shaped cross-section is formed by the opposing surface, the front surface, and the bottom surface, it is possible to appropriately receive the load and absorb the shock. Also, according to the vehicle interior part of the present invention, since the fixing part is provided only on one side with respect to the first recess, the fixing range of the shock absorption member is widened, and it is possible to stably receive the load. Also, according to the vehicle interior part of the present invention, since a plurality of reinforcing ribs are divided and arranged by the first recess, it is possible to obtain sufficient rigidity in a compact space. Also, according to the vehicle interior part of the present invention, since at least a part of the second recess on the bottom surface and the first recess on the front surface or the rear surface intersect, the rigidity of the connecting part between the bottom surface, which is the fixing surface, and the front surface or the rear surface is improved. Also, according to the vehicle interior part of the present invention, since the fixing part is arranged at the bottom of the rear surface and the first recess, that is, at a position avoiding the standing wall, it is possible to suppress an increase in the weight of the shock absorption member while efficiently improving the rigidity of the fixing part. Also, according to the vehicle interior part of the present invention, by arranging other member fixing parts such as a door pocket near the first recess of the shock absorption member, while improving the rigidity of the fixing part of the shock absorption member, it is possible to prevent the load input to the shock absorption member from being directly transmitted to other parts.

[0019] The following describes an example of the configuration of a side door component as an interior component for a vehicle according to one embodiment of the present invention (this embodiment). The embodiments described below are provided to facilitate understanding of the present invention and do not limit it. Furthermore, the present invention can be modified and improved without departing from its spirit, and of course, equivalents thereof are included in the present invention.

[0020] Furthermore, in the following explanations in this book, "front-rear direction (vehicle front-rear direction)" refers to the front-rear direction of the vehicle and is the direction in which the vehicle travels. Also, "inside-out direction (vehicle inside-out direction)" refers to the direction in which the vehicle's width (vehicle width direction) is the direction in which the vehicle is the direction in which it is the direction in which it is the direction in which it is the direction in which it is the direction in which it is the height of the vehicle (vehicle height direction) and is the direction in which the vehicle is the up and down when viewed from the front.

[0021] <Side door part 1> The side door component 1 equipped with the protector 20 according to this embodiment will be described with reference to Figures 1 to 16E. The side door component 1 consists of a door trim 1a located on the inside in the vehicle width direction and a door panel 1b located on the outside in the vehicle width direction of the door trim 1a and mounted on top of the door trim 1a. Specifically, as shown in Figure 2, the door trim 1a is formed in a multilayer structure by a base resin layer 1aa and a surface resin layer 1ab laminated on the inside in the width direction of the base resin layer 1aa.

[0022] Furthermore, a protector 20 made of synthetic resin such as polypropylene, formed by injection molding, is provided between the door trim 1a and the door panel 1b.

[0023] The protector 20, acting as an impact-absorbing member, is a member that increases the rigidity of the side door component 1 and absorbs the impact (load) applied during a side collision of the vehicle. In this embodiment, it is fixed to the surface of the base resin layer 1aa of the door trim 1a that faces the door panel 1b. The protector 20 may be made of a synthetic resin material other than polypropylene, and may be molded by a molding method other than injection molding.

[0024] Furthermore, as shown in Figures 3 and 4, the protector 20 and door pocket 1c are attached to the door trim 1a by a welded portion 1d formed by the application of heat or ultrasonic waves. The door pocket fixing portion 1e, which attaches the door pocket 1c to the door trim 1a, is located near the front recess 21c (first recess) of the protector 20, which will be described later, and more specifically, within the area surrounded by the front recess 21c (Figure 4). By attaching the protector 20 and door pocket 1c to the door trim 1a in this way, it is possible to prevent load input to the protector 20 from being directly transmitted to the door pocket 1c, which is another component.

[0025] Furthermore, if the protector 20 and door pocket 1c can be securely fixed to the door trim 1a, the protector 20 and door pocket 1c may be attached to the door trim 1a by fasteners such as tapping screws or rivets, rather than by welding to the joint 1d. Alternatively, the protector 20 and door pocket 1c may be configured to be attached to the door trim 1a by fitting resin claws into holes or other claws.

[0026] <Protector 20> Next, with reference to Figures 5 to 15, the details of each part of the protector 20 will be described. The protector 20 mainly consists of a front surface 21, a rear surface 22, a top surface 23, a bottom surface 24, a base surface 25, an opposing surface 26, an upper mounting plate 27, a lower mounting plate 28, and a middle mounting plate 29.

[0027] When attached to the door trim 1a, the protector 20 has a bottom surface 25 with upper mounting holes 27a, lower mounting holes 28a, and middle mounting holes 29a formed in the inward and outward directions, which serve as fixing parts for attachment to the door trim 1a, and an opposing surface 26 that faces the door panel 1b (Figures 5 and 6).

[0028] Furthermore, when attached to the door trim 1a, the protector 20 has a front surface 21 positioned forward in the front-rear direction, a rear surface 22 positioned backward, an upper surface 23 positioned upward in the vertical direction, and a lower surface 24 positioned downward, between the opposing surface 26 and the bottom surface 25 (Figures 5 and 6).

[0029] In other words, the protector 20, when attached to the door trim 1a, is mainly formed having a front surface 21 located on the front side in the front-rear direction and extending in the vertical and inward-outward directions, a rear surface 22 which is the back surface relative to the front surface 21, and an upper surface 23, lower surface 24, bottom surface 25, and opposing surface 26 which extend from the upper, lower, inner, and outer periphery of the front surface 21 to the rear side in the front-rear direction, respectively.

[0030] (Front 21) The front surface 21 is a front wall located on the front side in the front-rear direction and extending in the vertical and inward-outward directions (Figure 7). The front surface 21 is divided vertically into an upper front surface 21a and a lower front surface 21b by a front recess 21c. The front recess 21c has a bottom 21d and is formed recessed toward the rear surface 22 side relative to the upper front surface 21a and the lower front surface 21b. The front recess 21c is also formed extending inward-outward from the bottom surface 25 to the opposing surface 26.

[0031] (rear 22) The rear surface 22 is the surface that is the back surface to the front surface 21, and is located on the rear side of the protector 20 in the front-rear direction, extending in the vertical and inward-outward directions (Figure 8). The rear surface 22 is divided vertically into the upper rear surface 22a and the lower rear surface 22b by the middle rear surface 22c.

[0032] The upper rear portion 22a corresponds to the upper front portion 21a of the front portion 21, the lower rear portion 22b corresponds to the lower front portion 21b of the front portion 21, and the middle rear portion 22c corresponds to the bottom portion 21d of the recessed front portion 21c. With the middle rear portion 22c as a reference, the upper rear portion 22a and the lower rear portion 22b are recessed toward the front, and multiple reinforcing ribs 22d1, 22d2, and 22d3 are erected and formed within the recess.

[0033] In the recess of the upper rear surface 22a, a total of three reinforcing ribs are formed, erected from the rear surface 22: two reinforcing ribs 22d1 that connect the upper surface 23 and the middle rear surface 22c and extend in the vertical and front-rear directions, and one reinforcing rib 22d2 that connects the bottom surface 25 and the opposing surface 26 and extends in the inward-outward and front-rear directions (Figure 8). In addition, in the recess of the lower rear surface 22b, two reinforcing ribs 22d3 that connect the bottom surface 24 and the middle rear surface 22c and extend in the vertical and front-rear directions are formed, erected from the rear surface 22 (Figure 8). The number of reinforcing ribs 22d1, 22d2, and 22d3 is not particularly limited, and more may be provided.

[0034] Between the reinforcing ribs 22d1, 22d2 and reinforcing rib 22d3, the rear middle section 22c, which corresponds to the bottom 21d of the front recess 21c, is positioned. The multiple reinforcing ribs 22d1, 22d2 and reinforcing rib 22d3 are separated and positioned by the rear middle section 22c, which corresponds to the bottom 21d of the front recess 21c. In other words, the reinforcing ribs 22d1, 22d2 and reinforcing rib 22d3 are positioned separately on the rear upper section 22a and the rear lower section 22b, making it possible to obtain sufficient rigidity in a compact space.

[0035] Furthermore, since the reinforcing ribs 22d1, 22d2, and 22d3 are formed to be exposed on the rear surface 22, which is the open side formed when the mold is positioned, the shape of the reinforcing ribs 22d1, 22d2, and 22d3 can be easily changed by changing the shape of the mold. Therefore, by changing the shape of the reinforcing ribs 22d1, 22d2, and 22d3, for example, to a geometric shape such as a lattice or truss, the rigidity can be easily adjusted.

[0036] (Top surface 23) The upper surface 23 extends from the upper peripheral edges of the front surface 21 and rear surface 22 toward the rear, and is located above the protector 20 in the vertical direction, extending in the front-rear and inward-outward directions (Figure 9). The upper surface 23 has an upper projection 23a that protrudes further rearward than the rear surface 22 on the side of the opposing surface 26 (i.e., the outer side in the inward-outward direction). The upper surface 23 has a notch 23b inside the upper projection 23a of the protector 20, and is in an inverted L shape when viewed from above.

[0037] (Bottom surface 24) The lower surface 24 extends from the lower peripheral edges of the front surface 21 and rear surface 22 toward the rear, and is located below the protector 20 in the vertical direction, extending in the front-rear and inward-outward directions (Figure 10). The lower surface 24 has a lower projection 24a that protrudes further rearward than the rear surface 22 on the side of the opposing surface 26 (i.e., the outer side in the inward-outward direction). The lower surface 24 has a notch 24b inside the lower projection 24a of the protector 20, and is in an inverted L shape when viewed from below.

[0038] (Base 25) The bottom surface 25 extends from the inner periphery of the front surface 21 and the rear surface 22 toward the rear in the front-rear direction, and is located on the inside of the protector 20 in the in-out direction, extending in the vertical and front-rear directions (Figure 11). The bottom surface 25 is divided into an upper bottom surface 25a and a lower bottom surface 25b by a bottom surface recess 25c. The bottom surface recess 25c is formed as a recess on the side of the opposite surface 26 (i.e., the outside in the in-out direction of the vehicle) relative to the upper bottom surface 25a and the lower bottom surface 25b. Furthermore, the bottom surface recess 25c is formed to extend from the front surface 21 beyond the rear surface 22 in the front-rear direction.

[0039] (Opposite surface 26) The opposing surface 26 is the surface positioned opposite the door panel 1b when the protector 20 is fixed to the door trim 1a. The opposing surface 26 is divided vertically by the middle portion 26c, with the upper portion 26a and lower portion 26b of the opposing surface 26 (Figure 12). The upper portion 26a, lower portion 26b, and middle portion 26c of the opposing surface extend rearward in the front-rear direction from the outer periphery of the front upper portion 21a, front lower portion 21b, and bottom portion 21d of the front recess 21c, respectively. The opposing surface 26 has a free end portion 26d at its rear end.

[0040] (Upper mounting plate 27) An upper mounting plate 27 is formed on the upper side of the upper surface 23 (in other words, the upper side in the vertical direction of the protector 20), continuously from the upper part 25a of the bottom surface 25 (Figures 12 to 15). In detail, the upper mounting plate 27 extends upward from the inner periphery of the upper surface 23 and is formed to extend in the vertical and front-back directions.

[0041] The upper mounting plate 27 has an upper mounting hole 27a (fixing portion) that penetrates in the thickness direction (inward and outward direction), and is fixed to the door trim 1a by a welded portion 1d formed by welding to this upper mounting hole 27a. The upper mounting plate 27 has ribs 27b that extend vertically in both the front-rear and rear directions, and is slightly recessed outward (towards the opposing surface 26) relative to the upper part 25a of the bottom surface.

[0042] (Lower mounting plate 28) A lower mounting plate 28 is formed on the lower side of the bottom surface 24 (in other words, the lower side in the vertical direction of the protector 20) continuously from the lower part 25b of the bottom surface 25 (Figures 12 to 15). In detail, the lower mounting plate 28 extends downward from the inner periphery of the bottom surface 24 and is formed to extend in the vertical and front-back directions.

[0043] The lower mounting plate 28 has a lower mounting hole 28a (fixing portion) that penetrates in the thickness direction (inward-outward direction), and is fixed to the door trim 1a by a welded portion 1d formed by welding to this lower mounting hole 28a. The lower mounting plate 28 has ribs 28b that extend vertically in both the front-rear and rear directions, and is slightly recessed outward (towards the opposing surface 26) relative to the upper part of the bottom surface 25a.

[0044] (Inner mounting plate 29) An inner mounting plate 29 is formed on the rear side of the bottom recess 25c (in other words, the rear side in the front-rear direction of the protector 20) and extends continuously from the bottom recess 25c of the bottom surface 25 (Figures 12 to 15). In detail, the inner mounting plate 29 extends rearward from the rear peripheral edge of the bottom surface 25 and is formed to extend in both the vertical and front-rear directions.

[0045] The inner mounting plate 29 has an inner mounting hole 29a (fixing portion) that penetrates in the thickness direction (inward-outward direction), and is fixed to the door trim 1a by a welded portion 1d formed by welding to this inner mounting hole 29a. The inner mounting plate 29 has ribs 29b that extend in the front-rear direction in both its vertical direction, and a bottom recess 25c is formed by a slight recess toward the outside (towards the opposing surface 26) relative to the bottom surface 25.

[0046] <About the features of Protector 20> The protector 20 is attached to the door trim 1a in a cantilevered manner by three welded joints 1d formed by welding to the upper mounting hole 27a, the lower mounting hole 28a, and the middle mounting hole 29a, respectively (Figure 13).

[0047] Here, "cantilever" means that one end is fixed and the other end is free. Furthermore, "cantilever state" means a state in which one end is fixed and the other end is free. Furthermore, "cantilever structure" means a structure (cantilever) in which one end is fixed and the other end is free.

[0048] The protector 20 is fixed to the door trim 1a at one end (the side facing the bottom surface 25) in the inward and outward directions, while the other end (the side facing the opposing surface 26) is a free end 26d. When the protector 20 is attached to the door trim 1a in this cantilevered manner, it is possible to slow down the initial rise of load stress applied to the opposing surface 26 during a side impact.

[0049] Specifically, as shown in Figures 16A to 16E, when the door panel 1b deforms during a side impact and a load is applied to the opposing surface 26, first the free end 26d of the opposing surface 26 deforms inward (Figure 16B). At this time, as the opposing surface 26 is displaced inward, the upper surface 23 and lower surface 24 are crushed in a curved manner, starting from the notches 23b and 24b (Figures 16C to 16E). More specifically, as the opposing surface 26 is displaced inward, the protector 20 deforms so that the upper projection 23a of the upper surface 23 and the lower projection 24a of the lower surface 24 face inward and forward.

[0050] Thus, in the deformation process of the protector 20 during a side impact, if the protector 20 is attached to the door trim 1a in a cantilevered manner, the initial rise of load stress applied to the opposing surface 26 becomes gradual, thus improving energy absorption efficiency.

[0051] The upper mounting plate 27, lower mounting plate 28, and middle mounting plate 29, which are equipped with fixing parts, each have ribs 27b, rib 28b, and rib 29b, respectively, and are formed to protrude in the direction from the bottom surface 25 toward the opposing surface 26. With this configuration, the rigidity of the fixing parts is improved by the fact that they are formed to protrude, and the fixing of the protector 20 to the door trim 1a is stabilized.

[0052] If the upper mounting plate 27, lower mounting plate 28, and middle mounting plate 29, which are equipped with fixing parts, are shaped to protrude from the bottom surface 25, a space will be created between the base material of the door trim 1a and the fixing surface of the fixing part. By forming the welded part 1d by welding with a space created between the base material surface of the door trim 1a and the fixing surface of the fixing part by ribs 27b, rib 28b, and rib 29b, the fixing after welding becomes stable and the appearance is also good.

[0053] The upper surface 23 and lower surface 24 of the protector 20 have upper protrusions 23a and lower protrusions 24a that project further rearward than the rear surface 22 on the side of the opposing surface 26 (i.e., outward) (Figures 9 and 10). With this configuration, the protector 20 has an inverted L-shape structure (inverted L-shape) when viewed from above and below, so that it is possible to appropriately absorb the impact applied to the protector 20 during a side collision while also making the protector 20 lighter.

[0054] Here, the inverted L-shaped structure of the protector 20 in top and bottom views means that, on the top surface 23 and bottom surface 24, the presence of top protrusions 23a and 24a means that notches 23b and 24b are formed on the rear side of the rear surface 22. In this way, considering the impact absorption performance against side impacts, and taking into account the parts to be strengthened and the parts to be weakened, it becomes possible to appropriately form an inverted L-shaped structure rotated by 90 degrees.

[0055] The opposing surface 26 of the protector 20 is inclined in a direction that approaches the bottom surface 25 (inward) as it moves forward from the free end 26d at its rear end (Figures 9 and 10). This inclination of the opposing surface 26, which is the contact surface against impact, allows the free end 26d, one end of the opposing surface 26, to make contact first. Furthermore, the inclined surface of the opposing surface 26 that contacts the door panel 1b simplifies the structure of the mold used to manufacture the protector 20.

[0056] Furthermore, since a fixing portion is formed on the bottom surface 25 located inside the free end 26d of the opposing surface 26, which is the contact surface of the protector 20 attached to the door trim 1a in a cantilevered manner, it is possible to reliably receive the load and absorb the impact.

[0057] In a top view of the protector 20, the upper mounting hole 27a and the upper mounting plate 27 are positioned opposite the upper projection 23a as fixing parts. In a bottom view of the protector 20, the lower mounting hole 28a and the lower mounting plate 28 are positioned opposite the lower projection 24a as fixing parts (Figures 9 and 10). With this configuration, the opposing surface 26, the front surface 21, and the bottom surface 25 form a U-shaped (approximately U-shaped) cross section, making it possible to appropriately receive loads and absorb impacts.

[0058] The front surface 21 of the protector 20 has a front recess 21c (first recess) that extends in the width direction, and the upper mounting hole 27a, lower mounting hole 28a, and middle mounting hole 29a, which serve as fixing parts, are provided only on the rear side of the bottom 21d of the front recess 21c in the front-rear direction (Figures 12 to 15). With this configuration, the fixing parts are positioned on the opposite side of the front recess 21c, and the fixing range of the protector 20 is widened, making it possible to stably withstand loads. In addition, since the fixing parts are positioned on the rear surface 22 and the bottom 21d of the front recess 21c (first recess), that is, in a position that avoids the vertical wall, it is possible to efficiently improve the rigidity of the fixing parts while suppressing an increase in the weight of the protector 20.

[0059] A portion of the front recess 21c (first recess) of the front surface 21 of the protector 20 is positioned at the same height in the vertical direction as the bottom recess 25c (second recess) of the bottom surface 25 (Figures 6, 7, 11, and 15). With this configuration, the front recess 21c and the bottom recess 25c intersect in at least a portion of the same area, thereby improving the rigidity of the connection between the bottom surface 25, which is the fixing surface to the door trim 1a, and the front surface 21 and rear surface 22. Furthermore, the intersecting of the front recess 21c and the bottom recess 25c is offset in at least a portion of the same area in the vertical direction, which further improves the rigidity of the connection between the bottom surface 25 and the front surface 21 and rear surface 22.

[0060] <Variation> Next, the protector 20X as an impact-absorbing member according to the modified example will be described with reference to Figures 17 to 19. In the following description of this modified example, parts that are the same as in the above embodiment will be given the same names and reference numerals and their descriptions will be omitted, with the focus being on the differences.

[0061] The protector 20X is equipped with reinforcing ribs 26Xe and 26Xf on the opposing surface 26X. Specifically, one reinforcing rib 26Xe is erected on each of the upper part 26Xa, lower part 26Xb, and middle part 26Xc of the opposing surface. In addition, reinforcing ribs 26Xf are formed on the periphery of the upper part 26Xa and middle part 26Xc of the opposing surface, surrounding them in the vertical and forward directions.

[0062] Preferably, each reinforcing rib 26Xe, 26Xf is inclined to move inward as it is directed from the front to the rear. By forming reinforcing ribs 26Xe, 26Xf on the opposing surface 26X in this way, it becomes possible to effectively absorb impacts.

[0063] Furthermore, in the above embodiment, the protector 20 was described as being attached to the door trim 1a and positioned opposite the door panel 1b, but the mounting relationship may be reversed. In other words, as long as the impact can be suitably absorbed between the door trim 1a and the door panel 1b, the protector 20 can be attached to either of them.

[0064] Furthermore, although the above embodiment described an example of a side door component 1 located on the right side of the vehicle, it is also possible to arrange the side door component on the left side of the vehicle. Moreover, the arrangement of each fixing part in the protector 20 is not limited to the above embodiment, and it is also possible to reverse the front-to-back positional relationship.

[0065] Although the above embodiment was described using vehicle interior components as an example, the technical concept of the present invention can be applied not only to vehicles but also to interior components for vehicles such as aircraft, ships, and industrial machinery.
