[0006] Problems to be solved by the invention

[0007] However, the box-shaped protector included in the side door component of Patent Document 1 is a structure that maintains rigidity, and improvement in energy absorption performance is desired.

[0008] Therefore, the present invention has been made in view of the above-mentioned problems, and an object of the present invention is to provide a vehicle interior part including a shock absorbing member that improves energy absorption efficiency during a side collision and is lightweight and compact.

[0009] Technical means to solve the problem

[0010] The problem is solved in the following manner, that is, according to the present invention, the vehicle interior parts include: a door panel; a door trim installed on the door panel; and an impact absorbing component, arranged between the door panel and the door trim, and installed on one of the door panel or the door trim, the impact absorbing component has: a bottom surface, formed with a fixing portion installed on one of the door panel or the door trim; and an opposing surface, opposite to the other of the door panel or the door trim, the impact absorbing component is installed on one of the door panel or the door trim in a cantilever form.

[0011] In the vehicle interior component of the present invention configured as described above, the impact absorbing member is cantilevered to one of the door panel or the door trim, thereby alleviating the initial increase in load stress applied to the opposing surface during a side collision.

[0012] Moreover, preferably, the impact absorbing member has a front surface arranged in the front, a rear surface arranged in the rear, an upper surface arranged above, and a lower surface arranged below between the opposing surface and the bottom surface, and the impact absorbing member has an inverted L-shape when viewed from above and above.

[0013] According to the above configuration, the shock absorbing member has an inverted L-shape in plan view and bottom view, and thus can appropriately absorb the shock applied to the shock absorbing member during a side collision, while also reducing the weight of the shock absorbing member.

[0014] Furthermore, it is preferable that the facing surface of the impact absorbing member be inclined in a direction approaching the bottom surface as it moves forward or backward.

[0015] According to the above configuration, the facing surface that serves as the contact surface for the impact is inclined, so that one end portion of the facing surface can be brought into contact first.

[0016] Furthermore, it is preferable that the fixing portion of the shock absorbing member is formed to protrude from the bottom surface toward the facing surface.

[0017] According to the above configuration, the fixing portion is formed to protrude, thereby increasing the rigidity of the fixing portion and stabilizing the fixing to the door panel or the door trim.

[0018] Furthermore, it is preferable that the facing surface, the front surface, and the bottom surface form a U-shaped cross section.

[0019] According to the above configuration, a U-shaped cross section is formed by the facing surface, the front surface, and the bottom surface, so that the load can be appropriately received and the impact can be absorbed.

[0020] Furthermore, preferably, a first recess extending in the vehicle width direction is formed on the front surface or the rear surface of the impact absorbing member, and the fixing portion is provided on only one side, frontward or rearward, of a bottom of the first recess in the vehicle longitudinal direction.

[0021] According to the above configuration, since the fixing portion is provided only on one side of the first recessed portion, the fixing range of the shock absorbing member is expanded, and the load can be stably received.

[0022] Furthermore, it is preferable that a plurality of reinforcing ribs be provided on the rear surface of the shock absorbing member, and the bottoms of the first recessed portions be arranged correspondingly between the plurality of reinforcing ribs.

[0023] According to the above configuration, the plurality of reinforcing ribs are arranged in a separated manner by the first recessed portion, so that necessary and sufficient rigidity can be obtained in a compact space.

[0024] Furthermore, preferably, the bottom surface of the shock absorbing member includes a second recessed portion recessed toward the facing surface, and a portion of the first recessed portion is disposed at the same height as the second recessed portion in the vehicle vertical direction.

[0025] According to the above configuration, the second recessed portion of the bottom surface intersects at least a portion of the first recessed portion of the front or rear surface, thereby improving the rigidity of the connection portion between the bottom surface serving as the fixing surface and the front or rear surface.

[0026] Furthermore, it is preferable that the fixing portion is provided on a rear side relative to the rear surface and the bottom of the first recessed portion in the vehicle front-rear direction.

[0027] According to the above configuration, the fixing portion is arranged on the rear surface and the bottom of the first recess, ie, at a position away from the standing wall. This can effectively improve the rigidity of the fixing portion while suppressing an increase in weight of the shock absorbing member.

[0028] Moreover, preferably, it further includes: another component mounted on one of the door panel or the door trim, and the other component fixing portion for mounting the other component on one of the door panel or the door trim is arranged near the first recessed portion of the impact absorbing component.

[0029] According to the above structure, by arranging a fixing portion of another component such as a door pocket near the first recess of the shock absorbing member, the rigidity of the fixing portion of the shock absorbing member can be improved, and the load applied to the shock absorbing member can be prevented from being directly transmitted to other parts.

[0030] Effects of the Invention

[0031] According to the vehicle interior component of the present invention, the impact absorbing member is mounted in a cantilever manner on either the door panel or the door trim, thereby alleviating the initial increase in load stress applied to the opposing surface during a side collision.

[0032] Furthermore, according to the vehicle interior component of the present invention, the shock absorbing member has an inverted L-shape in plan view and bottom view, thereby suitably absorbing the shock applied to the shock absorbing member during a side collision and reducing the weight of the shock absorbing member.

[0033] Furthermore, according to the vehicle interior component of the present invention, the facing surface of the contact surface with respect to the impact is inclined, so that one end portion of the facing surface can be brought into contact first.

[0034] Furthermore, according to the vehicle interior component of the present invention, the fixing portion is formed to protrude, so that the rigidity of the fixing portion is improved, and the fixing to the door panel or door trim is stabilized.

[0035] Furthermore, according to the vehicle interior component of the present invention, since the facing surface, the front surface, and the bottom surface form a U-shaped cross section, the vehicle interior component can appropriately receive loads and absorb shocks.

[0036] Furthermore, according to the vehicle interior component of the present invention, the fixing portion is provided only on one side of the first recessed portion, thereby expanding the fixing range of the shock absorbing member and enabling the load to be stably received.

[0037] Furthermore, according to the vehicle interior component of the present invention, the plurality of reinforcing ribs are arranged in a separated manner by the first recessed portion, and therefore necessary and sufficient rigidity can be obtained in a compact space.

[0038] Furthermore, according to the vehicle interior component of the present invention, the second recessed portion of the bottom surface intersects at least a portion of the first recessed portion of the front or rear surface, thereby improving the rigidity of the connection portion between the bottom surface serving as the fixing surface and the front or rear surface.

[0039] Furthermore, according to the vehicle interior component of the present invention, the fixing portion is arranged on the rear surface and the bottom of the first recess, that is, at a position away from the vertical wall. This can effectively improve the rigidity of the fixing portion while suppressing an increase in weight of the shock absorbing member.

[0040] Furthermore, according to the vehicle interior component of the present invention, by arranging a fixing portion for another component such as a door storage clip near the first recess of the shock absorbing member, the rigidity of the fixing portion of the shock absorbing member can be improved, and the load applied to the shock absorbing member can be prevented from being directly transmitted to other components.

[0112] The following describes an example structure of a side door component as a vehicle interior component, according to one embodiment of the present invention (this embodiment). The embodiments described below are intended to facilitate understanding of the present invention and do not limit the present invention. Furthermore, the present invention is susceptible to modification and improvement without departing from the spirit of the present invention, and the present invention naturally encompasses equivalents thereof.

[0113] In the following descriptions of this specification, the term "front-rear direction (vehicle front-rear direction)" corresponds to the front-rear direction of the vehicle and is the direction that coincides with the vehicle's travel direction. Furthermore, the term "inside-outside direction (vehicle inside-outside direction)" corresponds to the vehicle's width direction (vehicle width direction). The term "up-down direction (vehicle up-down direction)" refers to the vehicle's height direction (vehicle height direction) and is the direction that coincides with the vehicle's height when viewed from the front.

[0114] <Side door part 1>

[0115] Reference Figures 1 to 16E The side door part 1 including the protector 20 of this embodiment will be described. The side door part 1 includes: a door trim 1a located on the inner side in the vehicle width direction; and a door panel 1b located on the outer side in the vehicle width direction of the door trim 1a and mounted on the door trim 1a. Specifically, Figure 2 As shown, the door trim 1a is formed into a multi-layer structure including a base resin layer 1aa and a skin resin layer 1ab laminated on the inner side of the base resin layer 1aa in the width direction.

[0116] Furthermore, a protector 20 made of a synthetic resin such as polypropylene and formed by injection molding is disposed between the door trim 1 a and the door panel 1 b .

[0117] The protector 20, a shock-absorbing member, is used to increase the rigidity of the side door component 1 and absorb 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 on the door panel 1b side. The protector 20 may be made of a synthetic resin material other than polypropylene and may be formed by a molding method other than injection molding.

[0118] Moreover, if Figure 3 and Figure 4 As shown, the protector 20 or the door storage clip 1c is mounted on the door trim 1a using a welded portion 1d formed by applying heat or ultrasonic waves. The door storage clip fixing portion 1e for mounting the door storage clip 1c on the door trim 1a is arranged near the front surface recess 21c (first recess) described below of the protector 20, more specifically, at a position surrounded by the front surface recess 21c ( Figure 4 By mounting the protector 20 or the door storage clip 1c on the door trim 1a in this manner, it is possible to prevent the load applied to the protector 20 from being directly transmitted to the door storage clip 1c as another component.

[0119] Alternatively, as long as the protector 20 or door storage clip 1c can be securely fixed to the door trim 1a, the protector 20 or door storage clip 1c may be attached to the door trim 1a using fasteners such as tapping screws or rivets, rather than using the welded portion 1d. Furthermore, the protector 20 or door storage clip 1c may be attached to the door trim 1a so that the resin claws engage with the holes or claws.

[0120] Protector 20

[0121] Next, refer to Figures 5 to 15 , details of each part of the protector 20 will be described. 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.

[0122] The protector 20 has a bottom surface 25, on which an upper mounting hole 27a, a lower mounting hole 28a, and a middle mounting hole 29a are formed in the inner and outer directions as a fixing portion for mounting on the door trim 1a when the protector 20 is mounted on the door trim 1a; and an opposing surface 26, which is opposite to the door panel 1b ( Figure 5 and Figure 6 ).

[0123] The protector 20 has a front surface 21 disposed in the front-rear direction between the facing surface 26 and the bottom surface 25 when mounted on the door trim 1a, a rear surface 22 disposed in the rear direction, an upper surface 23 disposed in the upper direction, and a lower surface 24 disposed in the lower direction. Figure 5 and Figure 6 ).

[0124] In other words, the protector 20 is mainly formed by having the following surfaces: a front surface 21 that is located on the front side in the front-to-rear direction and extends in the up-down direction and in the inside-outside direction when installed on the door trim panel 1a; a rear surface 22 that becomes the back side relative to the front surface 21; and an upper surface 23, a lower surface 24, a bottom surface 25 and an opposite surface 26 that extend from the upper side, the lower side, the inner side and the outer side of the front surface 21 to the rear side in the front-to-rear direction.

[0125] (Front surface 21)

[0126] The front surface 21 is a front wall located at the front side in the front-back direction and extending in the up-down direction and the inside-out direction ( Figure 7The front surface 21 is divided vertically into an upper front surface portion 21a and a lower front surface portion 21b by a front surface recess 21c. The front surface recess 21c has a bottom portion 21d that is recessed toward the rear surface 22 relative to the upper front surface portion 21a and the lower front surface portion 21b. Furthermore, the front surface recess 21c extends inward and outward from the bottom surface 25 to the facing surface 26.

[0127] (Rear surface 22)

[0128] The rear surface 22 is a surface that is the back side relative to the front surface 21, is located on the rear side of the protector 20 in the front-back direction, and extends in the up-down direction and the inside-out direction ( Figure 8 The rear surface 22 is divided into a rear surface upper portion 22a and a rear surface lower portion 22b by a rear surface middle portion 22c.

[0129] The upper rear surface portion 22a corresponds to the upper front surface portion 21a of the front surface 21, the lower rear surface portion 22b corresponds to the lower front surface portion 21b of the front surface 21, and the middle rear surface portion 22c corresponds to the bottom 21d of the front surface recess 21c. The upper rear surface portion 22a and the lower rear surface portion 22b are recessed forward with respect to the middle rear surface portion 22c. A plurality of reinforcing ribs 22d1, 22d2, and 22d3 are formed upright in the recessed portions.

[0130] A total of three reinforcing ribs are formed on the recessed portion of the upper portion 22a of the rear surface 22, and the three reinforcing ribs include: two reinforcing ribs 22d1, which connect the upper surface 23 with the middle portion 22c of the rear surface and extend in the up-down direction and the front-back direction; and one reinforcing rib 22d2, which connects the bottom surface 25 with the facing surface 26 and extends in the inside-out direction and the front-back direction ( Figure 8 ). In addition, two reinforcing ribs 22d3 are formed in the recessed portion of the rear surface lower portion 22b, which are erected from the rear surface 22. The two reinforcing ribs 22d3 connect the lower surface 24 with the rear surface middle portion 22c and extend in the up-down direction and the front-back direction ( Figure 8 ) In addition, the number of the reinforcing ribs 22d1, 22d2, and 22d3 is not particularly limited, and a plurality of them may be provided.

[0131] A rear surface middle portion 22c corresponding to the bottom 21d of the front surface recess 21c is disposed between the reinforcing ribs 22d1, 22d2, and 22d3. The plurality of reinforcing ribs 22d1, 22d2, and 22d3 are separated and disposed by the rear surface middle portion 22c corresponding to the bottom 21d of the front surface recess 21c. In other words, the reinforcing ribs 22d1, 22d2, and 22d3 are disposed separately on the rear surface upper portion 22a and the rear surface lower portion 22b. This allows for sufficient rigidity to be achieved in a compact space.

[0132] Furthermore, the reinforcing ribs 22d1, 22d2, and 22d3 are formed so as to be exposed on the rear surface 22 side, which is the open side formed by arranging the mold. Therefore, the shapes of the reinforcing ribs 22d1, 22d2, and 22d3 can be easily changed by changing the shape of the mold. Therefore, by changing the shapes of the reinforcing ribs 22d1, 22d2, and 22d3 to a geometric shape other than a lattice shape, such as a truss shape, the rigidity can be easily adjusted.

[0133] (upper surface 23)

[0134] The upper surface 23 extends from the upper periphery of the front surface 21 and the rear surface 22 to the rear side, is located on the upper side of the protector 20 in the vertical direction, and extends in the front-to-back direction and the inner-outer direction ( Figure 9 The upper surface 23 has an upper surface protrusion 23a on the side of the opposing surface 26 (i.e., on the outside in the inner and outer directions) that protrudes further rearward than the rear surface 22. The upper surface 23 has a notch 23b inside the upper surface protrusion 23a of the protector 20, forming an inverted L-shape when viewed from above.

[0135] (lower surface 24)

[0136] The lower surface 24 extends from the lower periphery of the front surface 21 and the rear surface 22 to the rear side, is located on the lower side of the protector 20 in the vertical direction, and extends in the front-to-back direction and the inner-outer direction ( Figure 10 The lower surface 24 has a lower surface protrusion 24a on the side facing the surface 26 (i.e., on the outside in the inside-outside direction) that protrudes further rearward than the rear surface 22. The lower surface 24 has a notch 24b inside the lower surface protrusion 24a of the protector 20, forming an inverted L-shape when viewed from above.

[0137] (Bottom 25)

[0138] The bottom surface 25 extends from the inner periphery of the front surface 21 and the rear surface 22 to the rear side in the front-rear direction, is located inside the inner-outer direction of the protector 20, and extends in the up-down direction and the front-rear direction ( Figure 11 The bottom surface 25 is divided into an upper bottom portion 25a and a lower bottom portion 25b by a bottom concave portion 25c. The bottom concave portion 25c is formed by being recessed toward the opposing surface 26 (i.e., outward in the vehicle interior-exterior direction) relative to the upper bottom portion 25a and the lower bottom portion 25b. Furthermore, the bottom concave portion 25c is formed to extend from the front surface 21 beyond the rear surface 22 in the front-to-rear direction.

[0139] (opposite surface 26)

[0140] The facing surface 26 is a surface that is arranged at 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 facing surface middle portion 26c. Figure 12 The facing surface upper portion 26a, the facing surface lower portion 26b, and the facing surface middle portion 26c extend from the outer peripheral edges of the front surface upper portion 21a, the front surface lower portion 21b, and the bottom 21d of the front surface recess 21c in the front-rear direction. The facing surface 26 has a free end portion 26d at its rear end.

[0141] (Upper mounting plate 27)

[0142] On the upper side of the upper surface 23 (in other words, the upper side of the protector 20 in the vertical direction), an upper side mounting plate 27 ( Figures 12 to 15 Specifically, the upper mounting plate 27 is formed to extend upward from the inner peripheral edge of the upper surface 23 and to extend in the up-down direction and the front-rear direction.

[0143] The upper mounting plate 27 has an upper mounting hole 27a (fixing portion) extending through the plate in the thickness direction (inside-outside direction). The upper mounting plate 27 is secured to the door trim panel 1a via a welded portion 1d formed by welding the upper mounting hole 27a. The upper mounting plate 27 has ribs 27b extending vertically in the front-to-back direction. The upper mounting plate 27 is slightly recessed outward (toward the facing surface 26) relative to the upper bottom surface 25a.

[0144] (Lower mounting plate 28)

[0145] On the lower side of the lower surface 24 (in other words, the lower side in the vertical direction of the protector 20), a lower side mounting plate 28 is formed continuously from the bottom surface lower portion 25b of the bottom surface 25. Figures 12 to 15 Specifically, the lower mounting plate 28 extends downward from the inner peripheral edge of the lower surface 24 and is formed to extend in the up-down direction and the front-rear direction.

[0146] The lower mounting plate 28 has a lower mounting hole 28a (fixing portion) extending through the plate in the thickness direction (inside-outside direction). The lower mounting plate 28 is secured to the door trim panel 1a via a welded portion 1d formed by welding the lower mounting hole 28a. The lower mounting plate 28 has ribs 28b extending vertically in the front-to-back direction, and is slightly recessed outward (toward the facing surface 26) relative to the upper bottom surface 25a.

[0147] (Middle side mounting plate 29)

[0148] On the rear side of the bottom concave portion 25c (in other words, the rear side in the front-rear direction of the protector 20), a middle side mounting plate 29 ( Figures 12 to 15 Specifically, the middle mounting plate 29 is formed to extend rearward from the rear peripheral edge of the bottom surface 25 and to extend in the up-down direction and the front-rear direction.

[0149] The center mounting plate 29 has a center mounting hole 29a (fixing portion) extending through the plate in the thickness direction (inside-outside direction). The center mounting plate 29 is secured to the door trim panel 1a via a welded portion 1d formed by welding the center mounting hole 29a. The center mounting plate 29 has ribs 29b extending in the front-to-back direction on its upper and lower sides. The center mounting plate 29 is slightly recessed outward from the bottom surface 25 (toward the facing surface 26), thereby forming a bottom recess 25c.

[0150] <Characteristics of Protector 20>

[0151] The protector 20 is mounted on the door trim 1a ( 29a ) in a cantilevered manner by welding the upper mounting hole 27a , the lower mounting hole 28a , and the middle mounting hole 29a to form three welded portions 1d . Figure 13 ).

[0152] Here, "cantilever" means one end is fixed and the other end is free. Furthermore, "cantilever state" refers to a state in which one end is fixed and the other end is free. Furthermore, "cantilever structure" refers to a structure (cantilever) in which one end is fixed and the other end is free.

[0153] The protector 20 is fixed to the door trim 1a at one end (bottom surface 25 side) in the inward and outward direction, while the other end (facing surface 26 side) forms a free end 26d. By attaching the protector 20 to the door trim 1a in a cantilevered manner, the initial increase in load stress applied to the facing surface 26 during a side collision can be mitigated.

[0154] Specifically, if 16A to 16E As shown, if the door panel 1b is deformed during a side collision and a load is applied to the facing surface 26, first, the free end portion 26d of the facing surface 26 is deformed inward ( Figure 16B At this time, as the facing surface 26 shifts inward, the upper surface 23 and the lower surface 24 are bent starting from the notches 23b and 24b, thereby crushing them ( Figures 16C to 16E More specifically, as the facing surface 26 shifts inward, the protector 20 is deformed so that the upper surface protrusion 23 a of the upper surface 23 and the lower surface protrusion 24 a of the lower surface 24 face inward and forward.

[0155] Thus, if the protector 20 is mounted in a cantilever manner on the door trim 1 a during deformation of the protector 20 in a side collision, the initial increase in load stress applied to the facing surface 26 is moderated, thereby improving energy absorption efficiency.

[0156] The upper mounting plate 27, lower mounting plate 28, and middle mounting plate 29, which include the fixing portion, have ribs 27b, 28b, and 29b, respectively, and are formed to protrude from the bottom surface 25 toward the opposing surface 26. According to this structure, by forming the fixing portion to protrude, the rigidity of the fixing portion is improved, and the fixation of the protector 20 to the door trim 1a is stabilized.

[0157] When the upper mounting plate 27, lower mounting plate 28, and center mounting plate 29, including the fixing portion, are shaped to protrude from the bottom surface 25, a space is created between the base material of the door trim 1a and the fixing seat surface of the fixing portion. By forming the welded portion 1d by welding, a space is created between the base material surface of the door trim 1a and the fixing seat surface of the fixing portion using ribs 27b, 28b, and 29b. This stabilizes the fixing after welding and improves the appearance.

[0158] 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 (protruding further rearward than the rear surface 22) on the side of the facing surface 26 (ie, the outer side). Figure 9 and Figure 10 With this structure, the protector 20 has an inverted L-shaped structure (inverted L-shaped) when viewed from above and below, thereby appropriately absorbing the impact applied to the protector 20 during a side collision and reducing the weight of the protector 20.

[0159] Here, the protector 20 having an inverted L-shaped structure in top and bottom views refers to the presence of an upper surface protrusion 23a and a lower surface protrusion 24a on the upper surface 23 and the lower surface 24, respectively, and the formation of notches 23b and 24b further rearward of the rear surface 22. In this manner, considering the impact absorption performance in a side collision, and considering the areas with strong and weak impact absorption performance, an inverted L-shaped structure rotated 90 degrees can be appropriately formed.

[0160] The facing surface 26 of the protector 20 is inclined toward the bottom surface 25 (inward) as it moves forward from the free end portion 26d at the rear end thereof. Figure 9 and Figure 10 Thus, the facing surface 26, which serves as the contact surface for the impact, is inclined, thereby enabling one end portion of the facing surface 26, namely the free end portion 26d, to contact first. Furthermore, the facing surface 26 that contacts the door panel 1b is an inclined surface, thereby simplifying the structure of the mold for manufacturing the protector 20.

[0161] Furthermore, since the fixing portion is formed on the bottom surface 25 located inside the free end portion 26 d of the facing surface 26 , which is the contact surface of the protector 20 mounted in a cantilever manner on the door trim 1 a , the load can be reliably received and the impact can be absorbed.

[0162] When the protector 20 is viewed from above, an upper mounting hole 27a and an upper mounting plate 27 serving as a fixing portion are arranged at a position opposite to the upper surface protrusion 23a. Furthermore, when the protector 20 is viewed from below, a lower mounting hole 28a and a lower mounting plate 28 serving as a fixing portion are arranged at a position opposite to the lower surface protrusion 24a. Figure 9 and Figure 10 According to this structure, a U-shaped (approximately U-shaped) cross section is formed by the facing surface 26, the front surface 21, and the bottom surface 25, so that the load can be appropriately received and the impact can be absorbed.

[0163] A front surface recess 21c (first recess) extending in the width direction is formed on the front surface 21 of the protector 20, and an upper mounting hole 27a, a lower mounting hole 28a, and a middle mounting hole 29a serving as a fixing portion are provided only on the rear side (behind the bottom 21d of the front surface recess 21c) in the front-to-back direction. Figures 12 to 15 With this structure, the fixing portion is positioned on the opposite side of the front surface recess 21c, expanding the fixing range of the protector 20 and enabling stable load bearing. Furthermore, the fixing portion is positioned between the rear surface 22 and the bottom 21d of the front surface recess 21c (first recess), avoiding the vertical wall. This reduces the weight of the protector 20 and effectively improves the rigidity of the fixing portion.

[0164] A portion of the front surface recess 21c (first recess) included in the front surface 21 of the protector 20 is arranged at the same height position (in the vertical direction) as the bottom surface recess 25c (second recess) included in the bottom surface 25. Figure 6 、 Figure 7 、 Figure 11 and Figure 15 With this structure, the front surface recess 21c and the bottom surface recess 25c at least partially intersect, thereby improving the rigidity of the connection between the bottom surface 25 and the front surface 21 or the rear surface 22, which is the fixing surface of the door trim 1a. In addition, the front surface recess 21c and the bottom surface recess 25c are at least partially offset and intersected in the vertical direction, thereby further improving the rigidity of the connection between the bottom surface 25 and the front surface 21 or the rear surface 22.

[0165] Modifications

[0166] Next, refer to Figures 17 to 19In the following description of this modification, the same components as those in the embodiment are given the same names and symbols (numerals) and their descriptions are omitted, with the description focusing on the differences.

[0167] The protector 20X includes reinforcing ribs 26Xe and 26Xf on the facing surface 26X. Specifically, one reinforcing rib 26Xe is erected on each of the facing surface upper portion 26Xa, the facing surface lower portion 26Xb, and the facing surface middle portion 26Xc. Furthermore, reinforcing ribs 26Xf are formed around the edges of the facing surface upper portion 26Xa and the facing surface middle portion 26Xc, encircling the upper and lower portions and the front.

[0168] Each reinforcement rib 26Xe, 26Xf is appropriately inclined toward the inner side as it moves from the front to the rear. In this way, the reinforcement ribs 26Xe and 26Xf are formed on the facing surface 26X, thereby being able to appropriately receive an impact.

[0169] Furthermore, in the above embodiment, the protector 20 is described as being mounted on the door trim 1a and opposite the door panel 1b. However, the relationship between the installation of the protector 20 may be reversed. In other words, as long as the door trim 1a and the door panel 1b can appropriately absorb impact, the protector 20 may be mounted on either side.

[0170] Furthermore, in the above embodiment, the side door component 1 is arranged on the right side of the vehicle as an example, but the side door component may also be arranged on the left side of the vehicle. Furthermore, the arrangement of the fixing portions in the protector 20 is not limited to the above embodiment, and the front-to-back positional relationship may be reversed.

[0171] Furthermore, in the above-described embodiment, vehicle interior parts are described as an example. However, the present invention is not limited to vehicles, and the technical concept of the present invention can also be applied to interior parts for vehicles such as aircraft, ships, and industrial machinery.
