Description

Title of the invention: VEHICLE INTERIOR COMPONENT technical field

[0001] The present technology described here relates to an interior vehicle component. Context

[0002] A door trim is known as an interior vehicle component. An example of a door trim includes an armrest that projects toward an interior side of the vehicle. The armrest comprises a projecting portion (an armrest body) that projects from an interior component body (a door trim body), a top surface element (switch frame) configured as part of a top surface of the armrest, and a side surface element (a trim) configured as part of an interior side surface of the vehicle. Such an interior vehicle component is described in Japanese patent publication 6439228. Summary

[0003] In the armrest configuration, which comprises several elements as described above, when the armrest elements are displaced by the load applied to the armrest by a passenger, a gap can be created between the armrest elements, and this degrades the design. Therefore, in order to improve the design, there is a requirement to eliminate the displacement of the armrest elements.

[0004] An object of the present technology described herein is to provide an interior vehicle component in which the elements of an armrest are less likely to move.

[0005] (1) An interior vehicle component according to the technology described herein comprises a A projecting portion extending towards an interior side of the vehicle and configured as an armrest, comprising a wall portion forming a side surface on the interior side of the vehicle, a top surface element mounted on the projecting portion and configured as the top surface of the armrest, and a side surface element. The top surface element comprises a top surface element body that covers the projecting portion from above and a mounting portion that extends from the top surface element body and has a through hole that opens in a top-down direction. The mounting portion comprises a first extension portion extending from the top surface element body towards the interior side of the vehicle, and a second extension portion extending downward from an end portion on the interior side of the vehicle. The first extension section is brought into contact with the wall section from the inside of the vehicle. The side surface element is mounted on the wall section of the protruding part to cover the interior side surface of the vehicle and is configured as an interior side surface of the armrest facing an interior space of the vehicle.The side surface element comprises a side surface element body which covers the wall portion from the inside of the vehicle and includes an upper portion which is on the inside of the vehicle of the first extension portion and the upper side of the first extension portion, and a first stop piece which extends from an outside side surface of the vehicle from the top of the through hole and is inserted into the through hole from above and is brought into contact with an internal surface of the through hole from the outside of the vehicle.

[0006] The side surface element includes the first stop piece, which is brought into contact with the inner surface of the hole opening into the first extension portion from the outside of the vehicle. Consequently, the side surface element is less likely to move towards the inside of the vehicle relative to the upper surface element, and a gap is less likely to form between the side surface element and the upper surface element. The second extension portion, which extends downward from the first extension portion, is stopped by the wall portion of the protruding part. The second extension portion is brought into contact with the wall portion from the inside of the vehicle. With this configuration, the upper surface element is less likely to move towards the outside of the vehicle relative to the protruding part.With the second extension portion contacting the wall portion from the inside of the vehicle, the upper surface element is less likely to rotate, causing the upper portion of the upper surface element to move towards the inside of the vehicle. If the upper surface element is rotated and the opening direction of the through hole changes, the assembly of the first stop piece and the inner surface of the through hole may be released. However, according to the technology described here, the upper surface element is less likely to rotate, and the first stop piece is less likely to come out of the through hole.

[0007] (2) Optionally, the upper surface element may comprise a second The stop piece is mounted on the wall section from the outside of the vehicle. The upper surface element includes the second extension part, which contacts the wall section from the inside of the vehicle, and the second stop piece, which is mounted on the wall section from the outside of the vehicle.

[0008] (3) Optionally, the first stop piece may include a part An outer extension extends from the outer side surface of the vehicle's body, extending from the outer side of the vehicle, and a downward extension extends from an outer side end of the vehicle. This extension is inserted into a hole opening from above and made contact with an inner surface of the hole opening from the vehicle's outer side. The outer extension may overlap a portion of the edge of the opening that forms part of the first extension from above.

[0009] Even if the first extension portion of the upper surface element moves upwards, the first extension portion is in contact with the outer extension portion and does not move further upwards. Consequently, the upper surface element is less likely to move upwards.

[0010] (4) Optionally, the mounting part may have a tubular shape and understand the through hole in the latter. The mounting part includes the through hole with a simple structure and the first stop piece is easily inserted into the through hole.

[0011] (5) Optionally, the mounting part may further include a part An extension that is plate-shaped and extends downward from the upper surface element body. The first extension may consist of two opposing plate-shaped sections extending from the lateral edges of the extension towards the inner side of the vehicle. The second extension may extend to connect the first two sections and face the extension. The through hole may be defined by the extension, the first two sections, and the second extension.

[0012] The mounting part includes the through hole with a simple structure and the first stop piece is easily and securely inserted into the through hole.

[0013] (6) Optionally, the second stop piece may include a projection of The mounting at its distal end allows the mounting protrusion to be fitted into a mounting hole in the wall portion and brought into contact with a hole edge of the mounting hole from a lower side. The upper surface element is less likely to move upwards.

[0014] (7) Optionally, the mounting part may further include a part an extension that has a plate-like shape and extends downwards from the upper surface element body. The first part of the extension may include two initial sections The extension sections are plate-shaped and positioned opposite each other, extending from the lateral edges of the extension section towards the interior of the vehicle. The second extension section can extend to connect the first two sections and faces the first extension section. The through hole can be defined by the extension section, the first two extension sections, and the second extension section. The mounting assembly includes the through hole with a simple structure, and the first stop piece is easily and securely inserted into the through hole.

[0015] According to the technology described here, an interior vehicle component is proposed in which the elements of an armrest are less likely to move. Brief description of the drawings

The front section 42 of the switch base body 41 is inserted into the front opening 23A from above. The upper wall portion 23 includes a central opening 23B into a central section with respect to the front-to-rear direction of the vehicle. The pull handle box 43 is inserted into the central opening 23B from above.

[0034] As illustrated in Figures 4 and 5, mounting projections 53A, 54A and stop pieces 52A, 55A are located on a lower surface of a peripheral edge portion of the switch base body 4L. As illustrated in [Fig. 4], the stop piece 52A and the mounting projections 53A, 54A are located on the inner vehicle side portion of the peripheral edge portion of the switch base body 4L. As illustrated in [Fig. 5], the mounting projections 53A, 54A and the stop piece 55A are located on the outer vehicle side portion of the peripheral edge portion of the switch base body 4L. The mounting projection 54A projects downwards from the switch base body 41 and is a flat projection. The mounting projection 54A includes a U-shaped through hole in its central portion. With such In this configuration, the 54A mounting protrusion is configured so that only the central part is deformed.

[0040] As illustrated in [Fig. 6], the decorative element body 71 includes stop pieces 74, 75 on the outer side surface of the vehicle 71A of the decorative element body 71. The stop pieces 74, 75 protrude from the outer side surface of the vehicle 71A of the decorative element body 71. As illustrated in [Fig. 10], the stop piece 74 is stopped by a portion of the upper edge of the wall portion 25. The stop piece 74 is disposed on the outer side of the vehicle relative to the wall portion 25. The stop piece 74 is in a front section of the decorative element body 71 which is a lower right portion of the decorative element body 71 in [Fig. 6]. As illustrated in [Fig.4], a mounting piece 41A protrudes downwards from an inner side portion of the vehicle from the peripheral portion of the switch base body 41 and the mounting piece 41A has a mounting hole 41B.The stop piece 75 is inserted into the mounting hole 41B of the mounting piece 41A from above.

[0041] As illustrated in [Fig. 8], a portion of the upper edge of the trim element 72 is folded back towards the outer side of the vehicle from the body of the decorative element 71. In order to fix the trim element 72 to the body of the decorative element 71, a folded portion of the trim element 72 is compressed from the outer side of the vehicle with a clamping device 12 (illustrated with an imaginary line in [Fig. 8]). As illustrated in [Fig. 6], the stop piece 74 of the front section of the vehicle is positioned opposite the upper edge of the body of the decorative element 71 so as not to come into contact with the clamping device 12.

[0042] Next, a mounting structure for the front section 42 of the switch base 40 and a front section of the decorative element 70 will be described. As illustrated in [Fig. 4], the switch base 40 includes a mounting portion 60 extending from the switch base body 4L. As illustrated in Figures 4 and 7, the mounting portion 60 includes an extension portion 63, first extension portions 61, and a second extension portion 62. The extension portion 63 is a plate element having surfaces facing the exterior side of the vehicle and the interior side of the vehicle. The extension portion 63 extends downward from the inner edge portion of the switch base body 4L. The first extension part 61 extends from an inner vehicle side edge portion of the switch base body 41 towards the inner vehicle side. The first extension parts 61 are plate elements that extend from a front edge and a rear edge of the extension part 63 towards the inner vehicle side. The first extension parts 61 are opposite to each other with respect to the front-to-rear direction. The second extension part 62 extends downward from an inner vehicle end of the first extension part 61. The second extension part 62 is a plate element that extends downward from the inner vehicle ends of the first extension parts 61. The second extension part 62 extends between the first front and rear extension parts 61 to connect them. As illustrated in [Fig.[7], the second extension portion 61 faces the extension portion 63. The second extension portion 62 is stopped by the upper edge portion of the wall portion 25 and is disposed on the vehicle's inner side of the wall portion 25. As illustrated in Figures 4 and 7, the mounting portion 60 includes a through hole 61A that passes through in a top-to-bottom direction. The mounting portion 60 has a tubular shape. The through hole 61A is defined by the first facing extension portions 61 and the facing extension portions 63 and the second facing extension portion 62. The mounting portion 60 is mounted on the upper edge of the wall portion 25. As illustrated in [Fig. 7], the upper edge portion of the wall portion 25 is mounted into the through hole 61A from the lower side.

[0043] As illustrated in [Fig. 6], the decorative element 70 comprises a first stop piece 81 that projects from the outer side surface of the vehicle 71A of the decorative element body 71. As illustrated in [Fig. 7], the first stop piece 81 has an L-shape and extends from an upper edge portion 71U of the decorative element body 71 towards the outer side of the vehicle and downwards. The upper edge portion 71U is higher than the first extension portions 61. The first stop piece 81 extends from the outer side surface of the vehicle 71A of the upper edge portion 71U of the decorative element body 71. The first stop piece 81 extends towards the through hole 61A. The body of decorative element 71 includes the upper edge part 71U which is on the vehicle's inner side of the first extension parts 61 and higher than the first extension parts 61.The first stop piece 81 is inserted into the through hole 61A from above, and thus, the first stop piece 81 is stopped by the inner surface of the through hole 61A. Specifically, the first stop piece 81 is in contact with the inner surface of the through hole 61A from the outside of the vehicle. The first stop piece 81 is in contact with the second extension part 62 from the outside of the vehicle.

[0044] Specifically, as illustrated in [Fig. 7], the first stop piece 81 comprises an outer extension portion 83 (a third extension portion), a downward extension portion 84 (a fourth extension portion), and ribs 81A. The outer extension portion 83 extends from the outer side surface 71A of the decorative element body 71 towards the outer side of the vehicle. The downward extension portion 84 extends downward from an outer side end portion of the vehicle of the outer extension portion 83. The downward extension portion 84 is inserted into the through hole 61A from above and is stopped by the second extension portion 62. The downward extension portion 84 is in contact with the second extension portion 62 from the outer side of the vehicle. The downward extension part 84 is in contact with an internal surface of the through hole 61 A.The outer extension portion 83 covers part of a hole edge of the through hole 61A of the mounting portion 60 from above. The ribs 81A project from the outer side vehicle surfaces of the outer extension portion 83 and the downward extension portion 84.

[0045] As illustrated in [Fig. 4], the switch base body 41 includes second stop pieces 46 on its inner side edge portion. The second stop piece 46 is adjacent to the second extension portion 62. As illustrated in [Fig. 8], the second stop piece 46 is mounted on the wall portion 25 from the outer side of the vehicle. The second stop piece 46 includes a mounting projection 46A at its distal end. The mounting projection 46A is mounted in a mounting hole 25A, which is in an upper edge portion of the wall portion 25, from the outer side of the vehicle. Therefore, the mounting projection 46A of the second stop piece 46 is stopped by a hole edge of the mounting hole 25A and is in contact with the hole edge of the mounting hole 25A from a lower side. The mounting protrusion 46A is in contact with an internal surface of the mounting hole 25A from a lower side.

[0046] The effects of this embodiment are then described. The decorative element 70 includes a first stop piece 81 which is in contact with the inner surface of the opening 61A in the first extension portion 61 from the outside of the vehicle. Consequently, the decorative element 70 is less likely to move towards the inside of the vehicle relative to the switch base 40, and a gap is less likely to be created between the decorative element 70 (in particular the upper edge portion 71U of the body of the decorative element 71) and the switch base 40. The second extension portion 62, which extends downwards from the first extension portion 61, is stopped by the wall portion 25 of the protruding portion 21. The second extension portion 62 is in contact with the wall portion 25 from the inside of the vehicle. With such a configuration, The switch base 40 is less likely to move towards the outside of the vehicle compared to the protruding portion 21. With the second extension portion 62 in contact with the wall portion 25 from the inside of the vehicle, the switch base 40 is less likely to move and be driven into rotation, causing the upper portion of the switch base 40 to move towards the inside of the vehicle (clockwise in [Fig. 7]). If the switch base 40 is driven into rotation and the opening direction of the through hole 61A changes, the assembly of the first stop piece 81 and the inner surface of the through hole 61A can be released. However, in this embodiment, the switch base 40 is less likely to be driven into rotation, and the first stop piece 81 is less likely to come out of the through hole 61A.

[0047] The switch base 40 includes the second stop piece 46, which is mounted on the wall portion 25 from the outside of the vehicle. The switch base 40 includes the second extension portion 62, which is in contact with the wall portion 25 from the inside of the vehicle, and the second stop piece 46, which is mounted on the wall portion 25 from the outside of the vehicle. With such a structure, the switch base 40 is also less likely to move in the inside-outside direction of the vehicle.

[0048] The first stop piece 81 comprises the outer extension portion 83 and the downward extension portion 84. The outer extension portion 83 extends from the outer side surface 71A of the decorative element body 71 towards the outer side of the vehicle. The downward extension portion 84 extends downward from the outer side end portion of the outer extension portion 83 and is inserted into the through hole 61A from above. Thus, the downward extension portion 84 is in contact with the inner surface of the through hole 61A from the outer side of the vehicle. The outer extension portion 83 covers a portion of the edge of the through hole 61A of the mounting portion 60 from above.

[0049] Even if the first extension portion 61 of the switch base 40 moves upwards, the first extension portion 61 remains in contact with the outer extension portion 83 and does not move further upwards. Therefore, the switch base 40 is less likely to move upwards.
