[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2007-137410 Summary of the Invention [Problem to be solved by the invention]

[0004] In the above-described conventional technology, if an occupant accidentally catches their toes on the interior covering member from above when getting in or out of the vehicle, or if an occupant inside the vehicle intentionally presses the interior covering member outward in the vehicle width direction with their toes to keep the vehicle door in an open position, there is a concern that a load will be applied to the interior covering member from the toes. In this way, if the load from the toes is applied to the thin-walled hinge portion through the interior covering member, there is a concern that the thin-walled hinge portion may deteriorate or break, or that the load applied from the toes may cause the exterior covering member or the interior covering member to fall off from the vehicle door. The present invention has been made in view of the above circumstances, and an object thereof is to provide a door garnish that is advantageous in terms of preventing it from falling off from a vehicle door while improving durability. [Means for solving the problem]

[0005] In order to achieve the above-mentioned object, one embodiment of the present invention is a door garnish comprising an outer member covering the outer surface of the lower part of a vehicle door comprising a door outer panel and a door inner panel, and an inner member covering the inner surface of the lower part of the vehicle door, wherein the outer member has a lower wall portion attached to the door outer panel and extending below the lower flange of the vehicle door and inward in the vehicle width direction from the lower flange to cover the lower part of the door, and an opening formed vertically through near the inner end of the lower wall portion on the inner side in the vehicle width direction, and the inner member is attached to the door inner panel and inserted from above into the opening with a gap formed between it and the peripheral portion of the opening, and has a first regulating portion that regulates displacement of the lower wall portion downward and outward in the vehicle width direction. [Effects of the Invention]

[0006] According to one embodiment of the present invention, a door garnish is provided with an outer member and an inner member, and the inner member is provided with a first restricting portion that is inserted from above into an opening in a lower wall portion of the outer member with a gap formed between the opening and the peripheral edge of the opening, and that restricts displacement of the lower wall portion downward and outward in the vehicle width direction. Therefore, when a load from the occupant's toes is applied to the outer member, the first regulating portion regulates the downward and outward displacement of the lower wall portion of the outer member in the vehicle width direction, thereby reducing the load applied to the outer member, which is advantageous in preventing the door garnish from falling off from the vehicle door while improving its durability.

DETAILED DESCRIPTION OF THE INVENTION

[0008] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. In the drawings, the symbol FR indicates the front in the longitudinal direction of the vehicle, the symbol IN indicates the inside in the width direction of the vehicle, the symbol OUT indicates the outside in the width direction of the vehicle, and the symbol UP indicates the top of the vehicle.

[0009] As shown in FIGS. 1 and 2, a vehicle door 10 includes a door outer panel 12 and a door inner panel 14. A lower flange 16, to which the peripheral edges of the door outer panel 12 and the door inner panel 14 are joined, protrudes downward from the lower end of the vehicle door 10. In Figures 1 and 2, reference numeral 18 denotes a side sill (vehicle body) extending in the fore-and-aft direction of the vehicle along the lower part of a door opening (not shown), and reference numeral 20 denotes a sealing member provided on the outer side of the lower part of the side sill 18 in the vehicle width direction and extending along the side sill 18.

[0010] As shown in Figures 1 and 2, the door garnish 22 of this embodiment comprises an outer member 24 that covers the outer surface 1202 located on the outer side of the lower part of the door outer panel 12 in the vehicle width direction, and an inner member 26 that covers the inner surface 1402 located on the inner side of the lower part of the door inner panel 14 in the vehicle width direction. The outer member 24 and the inner member 26 are made of synthetic resin, and in this embodiment, the same synthetic resin material is used for them. The inner member 26 is formed to have higher rigidity than the outer member 24 and is less likely to deform than the outer member 24.

[0011] As shown in Figures 1, 2, 3(A) and (B), the outer member 24 is composed of an outer main body wall portion 28, a plurality of outer side clips 30, a lower wall portion 32, a plurality of openings 34 and an inclined surface 36. The outer main body wall portion 28 has a plate shape that is elongated in the longitudinal direction of the vehicle, and covers the outer side in the vehicle width direction of the space below the lower part of the outer surface 1202 of the door outer panel 12. A plurality of outer side clips 30 are provided at intervals in the longitudinal direction of the outer main body wall portion 28 at a location near the upper end of the surface of the outer main body wall portion 28 facing the door outer panel 12, protruding inward in the vehicle width direction. The outer member 24 is detachably attached to the lower part of the door outer panel 12 by engaging the outer clips 30 with the respective attachment holes 1210 of the door outer panel 12 .

[0012] As shown in FIGS. 1 and 2, the lower wall portion 32 extends inward in the vehicle width direction from the lower portion of the outer main body wall portion 28 and has a plate shape that is elongated in the vehicle front-rear direction. When the outer main body wall portion 28 is attached to the door outer panel 12, the lower wall portion 32 is disposed below the lower flange 16 and extends inward in the vehicle width direction beyond the lower flange 16 to cover the lower side of the vehicle door 10. The lower wall portion 32 extends to a position that covers the gap between the vehicle door 10 and the side sill (vehicle body) 18 when the door opening is closed by the vehicle door 10, and its inner end portion 38 is formed to abut against the seal member 20 provided on the side sill 18, and an inclined surface 36 is formed at the outer portion of the inner end portion 38 in the vehicle width direction. The multiple openings 34 are formed at multiple locations spaced apart in the longitudinal direction (front-to-rear direction of the vehicle) of the outer member 24 near the inner end 38 on the inner side in the vehicle width direction of the lower wall portion 32, in other words, are formed by penetrating vertically at locations on the outer side in the vehicle width direction of the inclined surface 36, and in this embodiment, the openings 34 have an elongated rectangular shape in the longitudinal direction (front-to-rear direction of the vehicle) of the outer member 24. The inclined surface 36 is formed so as to slope upward from a position inside the opening 34 of the lower wall portion 32 in the vehicle width direction toward the inside in the vehicle width direction, and the inclined surface 36 is formed over the entire longitudinal length of the lower wall portion 32.

[0013] As shown in Figures 1, 2, 4(A) and (B), the inner member 26 is configured to include an inner main body wall portion 40, a plurality of inner side clips 42, a first restricting portion 44 and a second restricting portion 48. The inner main body wall portion 40 is shaped like a long, narrow plate extending in the fore-and-aft direction of the vehicle, and when the inner member 26 is attached to the door inner panel 14, it covers the lower part of the door inner panel 14 and the part of the outer member 24 that protrudes downward below the lower flange 16 of the vehicle door 10 from the inside in the vehicle width direction. On the outer surface of the inner main body wall portion 40 in the vehicle width direction, near the upper end facing the door inner panel 14, multiple inner side clips 42 are provided at intervals in the longitudinal direction of the inner main body wall portion 40 (front-to-rear direction of the vehicle) and protruding outward in the vehicle width direction. The inner member 26 is detachably attached to the lower part of the door inner panel 14 by engaging the inner clips 42 with the attachment holes 1410 of the door inner panel 14 . The lower portion of the inner main body wall portion 40 is formed as an inclined portion 46, which extends downward and inward in the vehicle width direction toward the inner end portion 38 of the lower wall portion 32 of the outer member 24. As shown in Figure 2, at a location displaced in the longitudinal direction of the vehicle from the opening 34, the lower end of the inclined portion 46 faces the sealing member 20 near the sealing member 20 with a gap in the vehicle width direction, and also faces the inclined surface 36 with a gap in the vertical direction.

[0014] A second restricting portion 48 is provided at the middle portion in the up-down direction of the surface of the inner main body wall portion 40 on the outer side in the vehicle width direction, so as to protrude from the inner main body wall portion 40 toward the outer side in the vehicle width direction. The second regulating portion 48 is positioned opposite the lower flange 16 of the vehicle door 10 and abuts against the lower flange 16 to regulate the displacement of the inner main body wall portion 40, i.e., the inner member 26, outward in the vehicle width direction, and multiple second regulating portions 48 are provided at intervals in the longitudinal direction of the inner member 26 (front-to-rear direction of the vehicle). The second restricting portion 48 has a contact surface 50 that comes into contact with the lower flange 16, and the contact surface 50 is provided with a buffer member 52 made of an elastic material such as rubber or elastomer. The buffer member 52 is provided between the abutment surface 50 and the lower flange 16 in contact with the lower flange 16, and the abutment surface 50 of the second regulating portion 48 abuts against the lower flange via the buffer member 52. In this embodiment, the buffer member 52 is provided so as to contact the lower flange 16, but the buffer member 52 and the lower flange 16 may be provided with a gap therebetween. The second restricting portion 48 includes an upper plate portion that protrudes substantially horizontally from the vehicle width direction outer surface of the inner main body wall portion 40 and extends in the longitudinal direction of the inner member 26, a bent plate portion that is bent downward from the tip of the upper plate portion and forms a contact surface 50, and a pair of end plate portions that protrude from the vehicle width direction outer surface of the inner main body wall portion 40 and connect both ends of the upper plate portion and the bent plate portion in the vehicle front-rear direction. In other words, the second restricting portion 48 is formed open downward, has a box shape, and ensures rigidity.

[0015] The first restricting portions 44 are provided at the lower end of the inclined portion 46 facing the plurality of openings 34, and a plurality of first restricting portions 44 are provided corresponding to the openings 34. The first regulating portion 44 is inserted from above into the opening 34 with a gap formed between it and the peripheral edge of the opening 34, and regulates downward displacement, outward displacement (deformation) in the vehicle width direction, and upward displacement of the lower wall portion 32 of the outer member 24. The first regulating portion 44 includes an upper regulating portion 44A extending from the lower end of the inclined portion 46, an insertion portion 44B extending from the lower end of the upper regulating portion 44A, and a lower regulating portion 44C extending from the lower end of the insertion portion 44B.

[0016] The insertion portion 44B is the portion that is inserted into the opening 34, and as shown in FIG. 1, the insertion portion 44B extends substantially vertically within the opening 34, with a gap being maintained between the outer peripheral edge of the opening 34 in the vehicle width direction and the inner peripheral edge of the opening 34 in the vehicle width direction, and also, although not shown, with a gap being maintained between the front peripheral edge of the opening 34 in the vehicle fore-and-aft direction and the rear peripheral edge of the opening 34 in the vehicle fore-and-aft direction. Therefore, in areas where no opening 34 is provided as described above, as shown in Figure 2, the lower end of the inclined portion 46 faces the inclined surface 36 with a gap in the vertical direction, so that the insertion portion 44B can be smoothly displaced in the vehicle width direction within the opening 34. The upper regulating portion 44A extends downward and outward in the vehicle width direction from the lower end of the inclined portion 46 and is connected to the upper end of the insertion portion 44B located above the opening 34; in other words, it extends inward in the vehicle width direction from the upper end of the insertion portion 44B and is arranged to face the upper surface of the lower wall portion 32. In this embodiment, the upper restricting portion 44A extends along the inclined surface 36 of the outer member 24 with a gap secured between the upper restricting portion 44A and the inclined surface 36. As shown in FIG. The downward regulating portion 44C extends from the lower end of the insertion portion 44B located below the opening 34 toward the vehicle width direction inward of the opening 34 and is arranged to face the lower surface of the lower wall portion 32 while maintaining a vertical gap.

[0017] As shown in Figure 1, the gap S1 in the vehicle width direction between the outer peripheral edge of the opening 34 in the vehicle width direction and the insertion portion 44B is larger than the gap S2 in the vehicle width direction between the inner peripheral edge of the opening 34 in the vehicle width direction and the insertion portion 44B, and even if a load is applied to the inner member 26 from the occupant's toes toward the outside in the vehicle width direction, the insertion portion 44B moves within the range of the gap S1, thereby preventing damage to the inner member 26 or the outer member 24. Furthermore, the gap S2 is formed smaller than the gap S1, so that even if a load is applied downward from the occupant's toes to the inner end portion 38 of the outer member 24, causing the outer member 24 to displace, the inclined surfaces 36 of the outer member 24 are securely engaged with the downward regulating portion 44C of the inner member 26, preventing the outer member 24 from coming off the inner member 26.

[0018] According to this embodiment, the inner member 26 is provided with a first regulating portion 44 that is inserted from above into the opening 34 of the lower wall portion 32 of the outer member 24 with a gap formed between the opening 34 and the peripheral edge of the opening 34, and that regulates downward and outward displacement of the lower wall portion 32 in the vehicle width direction. Therefore, when a load from the occupant's toes is applied to the outer member 24, the first regulating portion 44 regulates the downward and outward displacement of the lower wall portion 32 of the outer member 24 in the vehicle width direction, thereby reducing the load applied to the outer member 24. This is advantageous in terms of improving the durability of the door garnish 22 and preventing it from falling off the vehicle door 10.

[0019] In addition, according to this embodiment, the first regulating portion 44 has an insertion portion 44B that extends in the vertical direction and is inserted into the opening 34, and a downward regulating portion 44C that extends from the lower end of the insertion portion 44B toward the inside in the vehicle width direction more than the opening 34 and faces the lower surface of the lower wall portion 32. Therefore, when a load from the occupant's toes is applied to the outer member 24, the lower surface of the lower wall portion 32 abuts against the downward regulating portion 44C, thereby more reliably regulating the downward displacement of the lower wall portion 32, which is advantageous in reducing the load applied to the outer member 24 and is more advantageous in preventing the door garnish 22 from falling off from the vehicle door 10 while improving its durability. In addition, the gap (the gap on the inner side in the vehicle width direction) between the opening 34 and the first regulating portion 44 (insertion portion 44B) can be covered from below by the lower regulating portion 44C, which is advantageous in preventing foreign objects from entering the space between the inner member 26 and the side sill 18 from below through the gap.

[0020] Furthermore, according to this embodiment, the first regulating portion 44 includes an upper regulating portion 44A that extends inward in the vehicle width direction from the upper end of the insertion portion 44B and faces the upper surface of the lower wall portion 32. Therefore, when a load from the occupant's toes is applied to the outer member 24, the upper regulating portion 44A regulates the upward displacement of the lower wall portion 32, which is advantageous in reducing the load applied to the outer member 24 and is more advantageous in preventing the door garnish 22 from falling off from the vehicle door 10 while improving its durability. Furthermore, the first regulating portion 44 can form a maze-shaped gap between the first regulating portion 44 and the lower wall portion 32 by using the lower regulating portion 44C, the insertion portion 44B, and the upper regulating portion 44A, which is more advantageous in preventing foreign matter from entering the space between the inner member 26 and the side sill 18 through the gap between the outer peripheral edge of the opening 34 in the vehicle width direction and the first regulating portion 44.

[0021] Furthermore, according to this embodiment, an inclined surface 36 that slopes upward toward the inside of the vehicle width direction is formed in a portion of the lower wall portion 32 that is more inward in the vehicle width direction than the opening 34, and the upper regulating portion 44A of the first regulating portion 44 extends along the inclined surface 36. Therefore, the maze shape of the gap between the upper regulating portion 44A and the inclined surface 36 can be made more complex, which is more advantageous in preventing foreign objects from entering the space between the inner member 26 and the side sill 18 through the gap between the outer peripheral edge of the opening 34 in the vehicle width direction and the first regulating portion 44.Furthermore, since the inclined surface 36 and the upper regulating portion 44A are inclined, this is advantageous in discharging foreign objects downward through the gap between the inclined surface 36 and the upper regulating portion 44A.

[0022] Furthermore, according to this embodiment, the inner member 26 has an inclined portion 46 that inclines downward and inward in the vehicle width direction toward the inner end portion 38 of the lower wall portion 32 of the outer member 24 . Therefore, even if the occupant places their toes on the inner member 26, the toes are smoothly guided downward along the inclined portion 46, allowing the toes to easily come off the inner member 26, which is advantageous in preventing the toes from getting caught on the inner end portion 38 of the outer member 24. This is advantageous in reducing the load applied to the outer member 24 from the occupant's feet, and is more advantageous in preventing the door garnish 22 from falling off from the vehicle door 10 while improving the durability of the door garnish 22.

[0023] Furthermore, according to this embodiment, the inner member 26 has a second regulating portion 48 that protrudes outward in the vehicle width direction from the outer surface of the inner member 26 in the vehicle width direction and is arranged opposite the lower flange 16 of the vehicle door 10, and abuts against the lower flange 16 to regulate displacement of the inner member 26 outward in the vehicle width direction. Therefore, when a load from the occupant's toes is applied to the inner member 26, the load applied to the inner member 26 is received by the lower flange 16 via the second regulating portion 48, which is advantageous in reducing the load applied from the inner member 26 to the outer member 24, and is more advantageous in preventing the door garnish 22 from falling off from the vehicle door 10 while improving its durability.

[0024] Furthermore, according to this embodiment, a buffer member 52 is provided on the contact surface 50 where the second restricting portion 48 contacts the lower flange 16 . Therefore, when a load from the occupant's toes is applied to the inner member 26, this is advantageous in suppressing the generation of unpleasant noises when the contact surface 50 of the second restricting portion 48 contacts the lower flange 16 via the buffer member 52, and is advantageous in ensuring the comfort of the occupant.

[0025] Furthermore, according to this embodiment, the lower wall portion 32 of the outer member 24 is extended to a position that covers the gap between the vehicle door 10 and the side sill 18 when the vehicle door 10 is closed, and its inner end portion 38 is formed to abut against the seal member 20 provided on the side sill 18, which is advantageous in preventing foreign matter from entering the space between the inner member 26 and the side sill 18 from between the inner end portion 38 of the outer member 24 and the side sill 18.
