Abstract
Description
[Technical field]
[0001] The present invention relates to an interior part for a vehicle, and more particularly to an interior part for a vehicle including an impact absorbing member. [Background technology]
[0002] There are known side doors for vehicles that are equipped with a synthetic resin protector (shock absorbing member) for absorbing shock during a side collision. For example, Patent Document 1 discloses a technology for a side door part (vehicle interior part) that includes a box-shaped shock absorbing material attached to one side of a door panel or door trim, and that forms a groove extending in the vehicle front-rear direction on the surface of the shock absorbing material that faces the other side of the door panel or door trim. [Prior art documents] [Patent documents]
[0003] [Patent Document 1] Patent No. 6540529 Summary of the Invention [Problem 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 there is a demand for improvement in the energy absorption performance.
[0005] Therefore, the present invention has been made in consideration of the above problems, and an object of the present invention is to provide a vehicle interior part that is equipped with a lightweight and compact impact absorbing member while improving energy absorption efficiency during a side collision. [Means for solving the problem]
[0006] The above problem is solved by the vehicle interior part of the present invention, which comprises a door panel, a door trim attached to the door panel, and 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, wherein the impact absorbing member has a bottom surface formed with a fixing portion that is attached to one of the door panel or the door trim, and an opposing surface that faces the other of the door panel or the door trim, and the impact absorbing member is attached to one of the door panel or the door trim in a cantilevered manner.
[0007] In the vehicle interior part of the present invention configured as described above, the impact absorbing member is attached in a cantilever fashion to one side of the door panel or door trim, making it possible to smooth the initial rise in load stress applied to the opposing surface during a side collision.
[0008] Furthermore, it is preferable that the impact absorbing member has a front surface located forward, a rear surface located rearward, an upper surface located upward, and a lower surface located downward between the opposing surface and the bottom surface, and that the impact absorbing member has an inverted L-shape when viewed from above and below. According to the above configuration, the impact absorbing member has an inverted L-shape when viewed from above and below, which makes it possible to reduce the weight of the impact absorbing member while appropriately absorbing the impact applied to the impact absorbing member during a side collision.
[0009] It is also preferable that the opposing surface of the impact absorbing member is inclined in a direction approaching the bottom surface as it extends forward or rearward. According to the above-described configuration, since the opposing surface which serves as a contact surface against an impact is inclined, it is possible for one end of the opposing surface to come into contact first.
[0010] It is also preferable that the fixing portion of the impact absorbing member is formed so as to protrude in a direction from the bottom surface toward the opposing surface. According to the above configuration, the fixing portion is formed to protrude, thereby improving the rigidity of the fixing portion and stabilizing the fixing to the door panel or the door trim.
[0011] It is also preferable that the opposing surface, the front surface and the bottom surface form a U-shaped cross section. According to the above-mentioned configuration, the opposing surface, the front surface and the bottom surface form a U-shaped cross section, so that it is possible to appropriately receive a load and absorb impacts.
[0012] In addition, it is preferable that a first recess extending in the vehicle width direction is formed on the front or rear surface of the impact absorbing member, and the fixing portion is provided only either forward or rearward of the bottom of the first recess in the vehicle fore-and-aft direction. According to the above configuration, since the fixing portion is provided only on one side of the first recess, the fixing range of the impact absorbing member is expanded, and it becomes possible to stably receive the load.
[0013] It is also preferable that a plurality of reinforcing ribs are provided on the rear surface of the impact absorbing member, and the bottom of the first recess is disposed in correspondence with a space between the plurality of reinforcing ribs. According to the above configuration, the multiple reinforcing ribs are arranged separated by the first recess, so that necessary and sufficient rigidity can be obtained in a compact space.
[0014] It is also preferable that the bottom surface of the impact absorbing member is provided with a second recess recessed in a direction toward the opposing surface, and that a portion of the first recess is positioned at the same height as the front second recess in the vehicle vertical direction. According to the above configuration, the second recess on the bottom surface and the first recess on the front or rear surface at least partially intersect, thereby improving the rigidity of the connection between the bottom surface, which is the fixed surface, and the front or rear surface.
[0015] In addition, it is preferable that the fixing portion be provided rearward of the rear surface and a bottom portion of the first recess in the vehicle front-rear direction. According to the above configuration, the fixing portion is positioned at the rear surface and the bottom of the first recess, i.e., at a position avoiding the vertical wall, thereby making it possible to efficiently improve the rigidity of the fixing portion while suppressing an increase in weight of the impact absorbing member.
[0016] It is also preferable that the vehicle further comprises another member that is attached to either the door panel or the door trim, and that an other member fixing portion that attaches the other member to either the door panel or the door trim is positioned in the vicinity of the first recess of the impact absorbing member. According to the above configuration, by arranging the fixing portion for another component, such as a door pocket, near the first recess of the impact absorbing member, it is possible to improve the rigidity of the fixing portion of the impact absorbing member while preventing the load input to the impact absorbing member from being directly transmitted to other components. Effect of the Invention
[0017] According to the vehicle interior part of the present invention, the impact absorbing member is attached in a cantilever fashion to one side of the door panel or door trim, making it possible to soften the initial rise in load stress applied to the opposing surface during a side collision. Furthermore, according to the vehicle interior part of the present invention, the impact absorbing member has an inverted L-shape when viewed from above and below, which makes it possible to reduce the weight of the impact absorbing member while appropriately absorbing the impact applied to the impact absorbing member during a side collision. Furthermore, according to the vehicle interior part of the present invention, since the opposing surface which serves as a contact surface against an impact is inclined, it is possible for one end of the opposing surface to come into contact first. Furthermore, according to the vehicle interior part of the present invention, the fixing portion is formed to protrude, thereby improving the rigidity of the fixing portion and stabilizing the fixing to the door panel or the door trim. Furthermore, according to the vehicle interior part of the present invention, the opposing surface, the front surface and the bottom surface form a U-shaped cross section, so that it is possible to appropriately receive a load and absorb impacts. Furthermore, according to the vehicle interior part of the present invention, the fixing portion is provided only on one side of the first recess, so that the fixing range of the impact absorbing member is expanded, making it possible to stably receive the load. Furthermore, according to the vehicle interior part of the present invention, the multiple reinforcing ribs are arranged separated by the first recess, so that necessary and sufficient rigidity can be obtained in a compact space. Furthermore, according to the vehicle interior part of the present invention, the second recess on the bottom surface and the first recess on the front or rear surface intersect at least in part, thereby improving the rigidity of the connection between the bottom surface, which is the fixing surface, and the front or rear surface. Furthermore, according to the vehicle interior part of the present invention, the fixing portion is positioned at the rear surface and the bottom of the first recess, i.e., at a position avoiding the vertical wall, so that it is possible to efficiently improve the rigidity of the fixing portion while suppressing an increase in weight of the impact absorbing member. Furthermore, according to the vehicle interior part of the present invention, by locating the fixing part for another part, such as a door pocket, near the first recess of the impact absorbing member, it is possible to improve the rigidity of the fixing part of the impact absorbing member while preventing the load input to the impact absorbing member from being directly transmitted to the other part.

[0019] Hereinafter, a configuration example of a side door part as a vehicle interior part according to one embodiment of the present invention (the present embodiment) will be described. Note that the embodiment described below is for the purpose of making the present invention easier to understand, and does not limit the present invention. The present invention may be modified or improved without departing from the spirit thereof, and the present invention naturally includes equivalents thereof.
[0020] In addition, in the following description, the "front-rear direction (front-rear direction of the vehicle)" corresponds to the front-rear direction of the vehicle, and is the direction that coincides with the direction in which the vehicle travels. The "inner-outer direction (inner-outer direction of the vehicle)" is the direction that coincides with the width direction of the vehicle (vehicle width direction). The "up-down direction (up-down direction of the vehicle)" refers to the height direction of the vehicle (vehicle height direction), and coincides with the up-down direction when the vehicle is viewed from the front.
[0021] <Side door part 1> A side door part 1 including a protector 20 according to this embodiment will be described with reference to Fig. 1 to Fig. 16E. The side door part 1 is composed of a door trim 1a located on the inner side in the vehicle width direction, and a door panel 1b located on the outer side of the door trim 1a in the vehicle width direction and attached to the door trim 1a by being overlapped thereon. Specifically, as shown in Fig. 2, the door trim 1a has a multilayer structure formed of a base resin layer 1aa and a skin resin layer 1ab laminated on the inner side in the width direction of the base resin layer 1aa.
[0022] Between the door trim 1a and the door panel 1b, a protector 20 made of synthetic resin such as polypropylene and formed by injection molding is disposed.
[0023] The protector 20 as an impact absorbing member is a member for increasing the rigidity of the side door part 1 and absorbing the impact (load) applied at the time of a side collision of the vehicle, and in this embodiment, is fixed to the surface of the base resin layer 1aa of the door trim 1a on the door panel 1b side. 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] 3 and 4, the protector 20 and the door pocket 1c are attached to the door trim 1a by a welded portion 1d formed by applying heat or ultrasonic waves. A door pocket fixing portion 1e for attaching the door pocket 1c to the door trim 1a is disposed near a front recess 21c (first recess) of the protector 20, which will be described later, more specifically, at a position surrounded by the front recess 21c (FIG. 4). By attaching the protector 20 and the door pocket 1c to the door trim 1a in this manner, it is possible to prevent the load input to the protector 20 from being directly transmitted to the door pocket 1c, which is another component.
[0025] If the protector 20 and the door pocket 1c can be reliably fixed to the door trim 1a, the protector 20 and the door pocket 1c may be attached to the door trim 1a by fasteners such as tapping screws or by rivets, instead of the welded portion 1d by welding. The protector 20 and the door pocket 1c may be configured to be attached to the door trim 1a by fitting a resin claw into a hole or a claw.
[0026] <Protector 20> Next, each part of the protector 20 will be described in detail with reference to Figures 5 to 15. The protector 20 has a front surface 21, a rear surface 22, an upper surface 23, a lower surface 24, a bottom surface 25, an opposing surface 26, an upper mounting plate 27, a lower mounting plate 28, and a middle mounting plate 29 as main components.
[0027] When attached to the door trim 1a, the protector 20 has a bottom surface 25 in which upper mounting holes 27a, lower mounting holes 28a, and middle mounting holes 29a are formed in the inward and outward directions as fixing parts for attaching the protector 20 to the door trim 1a, and an opposing surface 26 that faces the door panel 1b (Figures 5 and 6).
[0028] In addition, when the protector 20 is attached to the door trim 1a, between the opposing surface 26 and the bottom surface 25, the protector 20 has a front surface 21 located forward in the fore-and-aft direction, a rear surface 22 located rearward, an upper surface 23 located upward in the up-down direction, and a lower surface 24 located downward (Figures 5 and 6).
[0029] In other words, when the protector 20 is attached to the door trim 1a, it is formed mainly having a front surface 21 that is located at the front side in the fore-and-aft direction and extends in the up-and-down and inward-and-outward directions, a rear surface 22 that is the back side relative to the front surface 21, and an upper surface 23, a lower surface 24, a bottom surface 25 and an opposing surface 26 that respectively extend from the upper, lower, inner and outer peripheral edges of the front surface 21 to the rear side in the fore-and-aft direction.
[0030] (Front 21) The front surface 21 is a front wall located at the front side in the front-rear direction and extending in the up-down and inward-outward directions (FIG. 7). The front surface 21 is divided into an upper front surface 21a and a lower front surface 21b by a front surface recess 21c. The front surface recess 21c has a bottom 21d, and is recessed toward the rear surface 22 relative to the upper front surface 21a and the lower front surface 21b. The front surface recess 21c is formed extending in the inward-outward directions from the bottom surface 25 to the opposing surface 26.
[0031] (rear 22) The rear surface 22 is the reverse surface of the front surface 21, and is located on the rear side of the protector 20 in the front-rear direction and extends in the up-down and inward-outward directions (FIG. 8). The rear surface 22 is divided into an upper rear surface portion 22a and a lower rear surface portion 22b by a middle rear surface portion 22c.
[0032] The rear upper portion 22a corresponds to the front upper portion 21a of the front surface 21, the rear lower portion 22b corresponds to the front lower portion 21b of the front surface 21, and the rear middle portion 22c corresponds to the bottom portion 21d of the front recess portion 21c. Using the rear middle portion 22c as a reference, the rear upper portion 22a and the rear lower portion 22b are recessed forward, and a plurality of reinforcing ribs 22d1, 22d2, 22d3 are formed in the recess so as to stand upright.
[0033] In the recess of the rear upper part 22a, two reinforcing ribs 22d1 that connect the top surface 23 and the rear middle part 22c and extend in the up-down direction and the front-rear direction, and one reinforcing rib 22d2 that connects the bottom surface 25 and the opposing surface 26 and extends in the inward-outward direction and the front-rear direction are formed standing up from the rear surface 22 (FIG. 8). In addition, in the recess of the rear lower part 22b, two reinforcing ribs 22d3 that connect the bottom surface 24 and the rear middle part 22c and extend in the up-down direction and the front-rear direction are formed standing up from the rear surface 22 (FIG. 8). The number of reinforcing ribs 22d1, 22d2, and 22d3 is not particularly limited, and more than one reinforcing rib may be provided.
[0034] Between the reinforcing ribs 22d1, 22d2 and the reinforcing rib 22d3, a rear middle portion 22c corresponding to the bottom portion 21d of the front recess 21c is disposed. Since the reinforcing ribs 22d1, 22d2 and the reinforcing rib 22d3 are separated and disposed by the rear middle portion 22c corresponding to the bottom portion 21d of the front recess 21c, in other words, the reinforcing ribs 22d1, 22d2 and the reinforcing rib 22d3 are separately disposed in the rear upper portion 22a and the rear lower portion 22b, it is possible to obtain necessary and sufficient rigidity in a compact space.
[0035] Furthermore, since the reinforcing ribs 22d1, 22d2, and 22d3 are formed so as to be exposed to the rear surface 22 side, which is the open side formed by disposing the mold, 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, by changing to a geometric shape such as a lattice shape or a truss shape, the rigidity can be easily adjusted.
[0036] (Top surface 23) The upper surface 23 extends rearward from the upper peripheral edges of the front surface 21 and the rear surface 22, and is located on the upper side of the protector 20 in the up-down direction, extending in the front-rear direction and the inward-outward direction (FIG. 9). The upper surface 23 has an upper surface protruding portion 23a that protrudes rearward beyond 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 on the inside of the upper surface protruding portion 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 rearward from the lower periphery of the front surface 21 and the rear surface 22, and is located below the protector 20 in the up-down direction and extends in the front-rear and inward-outward directions (FIG. 10). The lower surface 24 has a lower surface protruding portion 24a that protrudes rearward beyond the rear surface 22 on the side of the opposing surface 26 (i.e., the outside in the inward-outward direction). The lower surface 24 has a notch 24b on the inside of the lower surface protruding portion 24a of the protector 20, and is in an inverted L shape when viewed from below.
[0038] (Bottom 25) The bottom surface 25 extends rearward in the front-rear direction from the inner periphery of the front surface 21 and the rear surface 22, and is located inside the inside-outside direction of the protector 20 and extends in the up-down and front-rear directions (FIG. 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 recessed toward the opposing surface 26 side (i.e., the outside in the inside-outside direction of the vehicle) relative to the bottom surface upper surface 25a and the bottom surface lower surface 25b. The bottom surface recess 25c is also formed extending in the front-rear direction from the front surface 21 beyond the rear surface 22.
[0039] (Opposite surface 26) The facing surface 26 is a surface that is disposed in a position facing the door panel 1b when the protector 20 is fixed to the door trim 1a. The facing surface 26 is divided into an upper facing surface 26a and a lower facing surface 26b by a middle facing surface 26c (FIG. 12). The upper facing surface 26a, the lower facing surface 26b, and the middle facing surface 26c extend rearward in the front-rear direction from the outer peripheral edges of the front upper surface 21a, the front lower surface 21b, and the bottom 21d of the front recess 21c, respectively. The facing surface 26 has a free end 26d at its rear end.
[0040] (Upper mounting plate 27) An upper mounting plate 27 is formed continuously from a bottom surface upper portion 25a of the bottom surface 25 on the upper side of the top surface 23 (in other words, on the upper side in the vertical direction of the protector 20) (FIGS. 12 to 15). In detail, the upper mounting plate 27 extends upward from the inner peripheral edge of the top surface 23 and is formed so as to extend in the vertical direction and the front-rear direction.
[0041] The upper mounting plate 27 has an upper mounting hole 27a (fixing portion) penetrating in the plate thickness direction (inside-outside direction), and is fixed to the door trim 1a by a welding portion 1d formed by welding the upper mounting hole 27a. The upper mounting plate 27 has ribs 27b extending in the up-down direction in the front-rear direction, respectively, and is slightly recessed outward (toward the opposing surface 26) with respect to the bottom surface upper portion 25a.
[0042] (Lower mounting plate 28) A lower mounting plate 28 is formed continuously from the bottom surface lower portion 25b of the bottom surface 25 on the lower side of the lower surface 24 (in other words, on the lower side in the vertical direction of the protector 20) (FIGS. 12 to 15). In detail, the lower mounting plate 28 extends downward from the inner peripheral edge of the lower surface 24, and is formed so as to extend in the vertical direction and the front-rear direction.
[0043] The lower mounting plate 28 has a lower mounting hole 28a (fixing portion) penetrating in the plate thickness direction (inside-outside direction), and is fixed to the door trim 1a by a welding portion 1d formed by welding the lower mounting hole 28a. The lower mounting plate 28 has ribs 28b extending in the up-down direction in the front-rear direction, respectively, and is slightly recessed outward (toward the opposing surface 26) with respect to the bottom surface upper portion 25a.
[0044] (Middle mounting plate 29) A middle mounting plate 29 is formed continuously from the bottom recess 25c of the bottom surface 25 on the rear side of the bottom recess 25c (in other words, on the rear side of the protector 20 in the front-rear direction) (FIGS. 12 to 15). In detail, the middle mounting plate 29 extends rearward from the peripheral edge on the rear side of the bottom surface 25 and is formed so as to extend in the up-down direction and the front-rear direction.
[0045] The middle mounting plate 29 has a middle mounting hole 29a (fixing portion) penetrating in the plate thickness direction (inside-outside direction), and is fixed to the door trim 1a by a welding portion 1d formed by welding the middle mounting hole 29a. The middle mounting plate 29 has ribs 29b extending in the front-rear direction in the top-bottom direction and is slightly recessed outward from the bottom surface 25 (in the direction approaching the opposing surface 26) to form a bottom surface recess 25c.
[0046] <Features of Protector 20> The protector 20 is attached in a cantilever fashion to the door trim 1a by three welded portions 1d formed by welding to the upper mounting hole 27a, the lower mounting hole 28a and the middle mounting hole 29a (FIG. 13).
[0047] Here, "cantilever" means that one end is fixed and the other end is free. Additionally, "cantilever state" means that one end is fixed and the other end is free. Additionally, "cantilever structure" means that one end is fixed and the other end is free (cantilever).
[0048] One end (bottom surface 25 side) of the protector 20 is fixed to the door trim 1a in the inside-outside direction, and the other end (opposing surface 26 side) is a free end 26d. When the protector 20 is attached to the door trim 1a in a cantilever manner in this manner, it is possible to make the initial rise of the load stress applied to the opposing surface 26 during a side collision gentler.
[0049] Specifically, as shown in Figures 16A to 16E, when the door panel 1b is deformed during a side collision and a load is applied to the opposing surface 26, first, the free end 26d of the opposing surface 26 is deformed inward (Figure 16B). At this time, as the opposing surface 26 is displaced inward, the upper surface 23 and the lower surface 24 are crushed and curved starting from the notches 23b, 24b (Figures 16C to 16E). More specifically, as the opposing surface 26 is displaced inward, the protector 20 is deformed such that the upper surface protrusion 23a of the upper surface 23 and the lower surface protrusion 24a of the lower surface 24 are directed inward and forward.
[0050] In this way, when the protector 20 is attached to the door trim 1a in a cantilevered manner, during the deformation process of the protector 20 during a side collision, the initial rise in the load stress applied to the opposing surface 26 is gradual, thereby improving the energy absorption efficiency.
[0051] The upper mounting plate 27, the lower mounting plate 28 and the middle mounting plate 29 each have a rib 27b, a rib 28b and a rib 29b, and are formed to protrude in a direction from the bottom surface 25 toward the opposing surface 26. According to this configuration, the fixing portions are formed to protrude, thereby improving the rigidity of the fixing portions, and the fixation of the protector 20 to the door trim 1a is stabilized.
[0052] When the upper mounting plate 27, the lower mounting plate 28, and the middle mounting plate 29, which are provided with the fixing parts, are shaped to protrude from the bottom surface 25, a space is provided between the base material of the door trim 1a and the fixing seat surface of the fixing parts. By forming the welding part 1d by welding in a state in which a space is provided between the base material surface of the door trim 1a and the fixing seat surface of the fixing parts by the ribs 27b, 28b, and 29b, the fixing after welding is stable and the appearance is also good.
[0053] The upper surface 23 and the lower surface 24 of the protector 20 have an upper surface protrusion 23a and a lower surface protrusion 24a on the opposing surface 26 side (i.e., on the outside), which protrude further rearward than the rear surface 22 (FIGS. 9 and 10). With this configuration, the protector 20 has an inverted L-shaped structure when viewed from above and below, so that it is possible to reduce the weight of the protector 20 while appropriately absorbing the impact applied to the protector 20 during a side collision.
[0054] Here, the inverted L-shaped structure when viewed from above and below the protector 20 means that the upper surface protrusion 23a and the lower surface protrusion 24a are present on the upper surface 23 and the lower surface 24, so that the notches 23b and 24b are formed rearward of the rear surface 22. In this way, in consideration of the shock absorbing performance against a side collision and the portions to be strengthened and weakened, it is possible to appropriately form an inverted L-shaped structure rotated 90 degrees.
[0055] The opposing surface 26 of the protector 20 is inclined in a direction (inward) approaching the bottom surface 25 as it moves forward from the free end 26d at the rear end (FIGS. 9 and 10). In this manner, the opposing surface 26, which serves as the contact surface against an impact, is inclined, so that the free end 26d, which is one end of the opposing surface 26, can contact first. In addition, since the opposing surface 26 that contacts the door panel 1b is an inclined surface, the structure of the mold for manufacturing the protector 20 can be simplified.
[0056] In addition, since a fixing portion is formed on the bottom surface 25 located inside the free end portion 26d of the opposing surface 26, which is the abutment surface of the protector 20 attached to the door trim 1a in a cantilever manner, it is possible to reliably receive the load and absorb the impact.
[0057] In a top view of the protector 20, an upper mounting hole 27a and an upper mounting plate 27 as fixing parts are disposed at a position facing the upper surface protrusion 23a. In a bottom view of the protector 20, a lower mounting hole 28a and a lower mounting plate 28 as fixing parts are disposed at a position facing the lower surface protrusion 24a (FIGS. 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, which makes it possible to appropriately receive a load and absorb an impact.
[0058] A front recess 21c (first recess) extending in the width direction is formed on the front surface 21 of the protector 20, and the upper mounting hole 27a, the lower mounting hole 28a, and the middle mounting hole 29a as the fixing parts are provided only on the rear side of the bottom 21d of the front recess 21c in the front-rear direction (FIGS. 12 to 15). With this configuration, the fixing parts are arranged on the opposite side of the front recess 21c, and the fixing range of the protector 20 is expanded, making it possible to stably receive the load. In addition, since the fixing parts are arranged on the rear surface 22 and the bottom 21d of the front recess 21c (first recess), that is, at a position avoiding 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 part of the front recess 21c (first recess) of the front surface 21 of the protector 20 is disposed at the same height as the bottom recess 25c (second recess) of the bottom surface 25 in the vertical direction (FIGS. 6, 7, 11, and 15). With this configuration, the front surface recess 21c and the bottom surface recess 25c intersect at least partially, improving the rigidity of the connection between the bottom surface 25, which is a fixed surface to the door trim 1a, and the front surface 21 or the rear surface 22. In addition, the front surface recess 21c and the bottom surface recess 25c intersect with at least a part offset in the vertical direction, further improving the rigidity of the connection between the bottom surface 25 and the front surface 21 or the rear surface 22.
[0060] <Modification> Next, a protector 20X as a shock absorbing member according to a modified example will be described with reference to Fig. 17 to Fig. 19. In the following description of this modified example, the same components as those in the above embodiment will be given the same names and symbols (numbers) and description will be omitted, and differences will be mainly described.
[0061] The protector 20X has reinforcing ribs 26Xe, 26Xf on the opposing surface 26X. Specifically, one reinforcing rib 26Xe is provided upright on each of the opposing surface upper portion 26Xa, the opposing surface lower portion 26Xb, and the opposing surface middle portion 26Xc. In addition, reinforcing ribs 26Xf are formed on the periphery of the opposing surface upper portion 26Xa and the opposing surface middle portion 26Xc so as to surround the top and bottom directions and the front.
[0062] It is preferable that each of the reinforcing ribs 26Xe, 26Xf is inclined so as to approach the inside from the front to the rear. By forming the reinforcing ribs 26Xe, 26Xf on the opposing surface 26X in this manner, it is possible to preferably absorb impacts.
[0063] In the above embodiment, the protector 20 is attached to the door trim 1a and is attached to a position facing the door panel 1b, but the attachment relationship may be reversed. In other words, the protector 20 may be attached to either the door trim 1a or the door panel 1b as long as the shock can be appropriately absorbed between the door trim 1a and the door panel 1b.
[0064] In the above embodiment, the side door component 1 is disposed on the right side of the vehicle, but the side door component may be disposed on the left side of the vehicle. The arrangement of the fixing parts of the protector 20 is not limited to the above embodiment, and the positional relationship in the front-rear direction may be reversed.
[0065] In the above embodiment, an interior part for a vehicle has been described as an example, but the technical concept of the present invention can be applied to interior parts for vehicles other than vehicles, such as aircraft, ships, and industrial machines. [Explanation of symbols]
