  However, as in Patent Document 1, when the resin core material (trim board) has a three-dimensional shape in which the cross section is closed and the skin material is formed in a shape corresponding to the three-dimensional shape of the resin core material, The shape of the resin core material may be limited due to limitations in molding the skin material. For example, in the case where the resin core material is provided with a three-dimensional shape that bulges into the vehicle interior, wrinkles may be generated in the skin material, or the skin material may be vacuum formed in advance according to the three-dimensional shape. There is a possibility that the surface material may be torn or glossed, and in order to avoid such a situation, it is necessary to limit the bulging height of the bulging portion.

  The present invention has been completed based on the above circumstances, and it is an object of the present invention to provide a door trim having excellent designability by improving the degree of freedom of the design of the door trim.

  In order to solve the above problems, the door trim of the present invention is in the form of a plate extending along a first direction and a second direction orthogonal to each other, and is bent along the first direction and the second door trim A trimboard having a bulging portion that bulges out to the vehicle interior side so as to form a substantially straight shape along the direction 2 and a plate surface on the vehicle interior side of the trimboard following the bulging portion And a wall member formed in a wall shape closing an end of the bulging portion in the second direction, and a wall member assembled to the trim board with an end of the surface member interposed. .

  According to the present invention, since the wall-like member is configured to be attached to the trim board while interposing the end of the skin material, the bulging height of the bulging portion can be increased, and the design is excellent. A door trim can be realized. Specifically, in a configuration in which the skin material covers the end plate side of the bulging portion together with the plate surface of the trim board on the vehicle interior side, the skin material bulging when the bulging height of the bulging portion is high. By being shaped according to the three-dimensional shape formed by the protrusion and the wall surface, wrinkles are generated in the surface material, or when the surface material is vacuum-formed according to the three-dimensional shape in advance, the surface material is broken. And there is a risk that a gross may occur. On the other hand, in the present invention, since the skin material does not cover the wall surface of the wall-like member, generation of wrinkles on the skin material can be suppressed regardless of the bulging height of the bulging portion, and It is possible to suppress the occurrence of breakage or gloss in the surface material when vacuum forming. For this reason, it is possible to suppress the occurrence of a situation in which the bulging height of the bulging portion of the trim board is limited due to the restriction in forming the skin material.

  In the above configuration, the wall-like member is provided with a plurality of locking portions to be locked to the trim board, and the plurality of locking portions are distributed along the end portion of the bulging portion. It may be done.

  According to the above configuration, by locking the wall-like member to the trim board, the end of the skin material can be pressed along the end of the bulging portion, and wrinkles or blurring may occur in the skin material. It can be suppressed.

  In the above configuration, the trim board is disposed in an attitude that causes the first direction to coincide with the vertical direction of the vehicle and causes the second direction to coincide with the longitudinal direction of the vehicle, and an upper board provided on the upper side of the vehicle And a lower board disposed below the upper board of the upper board, the bulging portion is formed at least on the front side of the upper board of the upper board, and the wall-like member is disposed in front of the upper board of the upper board It may be located at

  According to the above configuration, the door trim can realize a novel design having a bulging portion on the upper side and the front side of the vehicle that is easily visible to the passenger, and the wall member not covered with the skin material is the passenger. It can be arranged in front of the vehicle of the trim board which is hard to be seen from the car.

The trim board 11 having an elongated plate shape, the surface material 40 covering the surface (plate surface on the vehicle interior side) 20A of the trim board 11 (upper board 20 described later) and the end 45 of the surface material 40 And a wall-like member 50 assembled to the board 11 (upper board 20). In FIG. 1 and FIG. 2, the upper board 20 is shown in a state of being hidden by the skin material 40, and therefore, for the configuration relating to the upper board 20, the reference numerals thereof are shown by dotted lead lines. There is.

  The trim board 11 is formed, for example, by molding a synthetic resin material or a material obtained by mixing a synthetic resin material and a natural fiber (such as kenaf) into a plate shape. Further, as shown in FIG. 1, the trim board 11 is formed with the arm rest 13 so that a part thereof bulges toward the vehicle interior, and the inside handle opening 14, the speaker grille 15, and the door pocket 16 mag is provided.

  As shown in FIG. 1, the trim board 11 is divided into an upper board 20 disposed on the upper side of the vehicle and a lower board 18 disposed on the lower side of the upper board 20. The upper board 20 is the main body of the door trim upper 17 and constitutes this together with the skin material 40 and the wall-like member 50. Lower board mounting portion 27 (see FIG. 3) having mounting hole 27A on the lower side of the vehicle is provided on upper board 20, and a mounting projection (not shown) provided on lower board 18 is engaged with mounting hole 27A. By being stopped, the upper board 20 and the lower board 18 are assembled. The lower board 18 constitutes most of the door trim 10 except the door trim upper 17, and is a member also called a main board.

  As shown in FIG. 2 and FIG. 5, the trim board 11 has a bulging portion 25 which is bent along the vertical direction of the vehicle and is substantially straight in the longitudinal direction of the vehicle. Have. In other words, the trim board 11 is formed with a blow-out portion (half-tubular shape) bulging portion 25 extending along the longitudinal direction of the vehicle. Specifically, the upper board 20 constituting the trim board 11 has a substantially V shape in which the end on the vehicle front side (the end 25A of the bulging portion 25) protrudes toward the vehicle interior (see FIG. 5) Reference), the protruding height is formed so as to become lower toward the rear of the vehicle. That is, the bulging portion 25 is formed at least on the front side of the upper board 20 in the vehicle. In the present application, the “substantially straight shape” refers to a shape including a shape that gently bends to a degree that is not limited in molding the surface material 40 described later. In addition, “bending” includes bending in a manner in which two planes intersect, and bending in a curved shape.

  In detail, as shown in FIGS. 2 and 5, upper board 20 is erected along the vertical direction of the vehicle, and surface material 40 is laminated on surface 20A to constitute main surface 10A of door trim 10. And an upper surface portion 23 of the door trim 10 having an upper surface 10B formed by laminating the skin material 40 on the surface 20A and rising up from the upper end of the board main surface 21 toward the vehicle exterior. Is equipped. The board-side main surface portion 21 is shaped such that a portion on the front side of the vehicle bends in the inward direction of the vehicle as it goes upward. The bulging portion 25 is bent in a mode in which the board-side main surface portion 21 and the board-side upper surface portion 23 intersect in the vehicle vertical direction (in a mode in which corner portions are formed) (see FIG. 3) Each of the board-side main surface portion and the board-side upper surface portion extends in a substantially straight shape in the vehicle front-rear direction. Furthermore, the bulging portion 25 is shaped like a cone having a three-dimensional shape surrounded by the board-side main surface 21 and the board-side upper surface 23 in front of the vehicle, the cross-sectional area becoming smaller toward the vehicle interior. ing. The bulging portion 25 has an open shape in which the front end of the board-side main surface 21 and the front end of the board-side upper surface 23 are not connected in the three-dimensional shape. With the above-described configuration, the door trim 10 exhibits a novel design in which the bulging height of the bulging portion 25 is noticeable.

  In the upper board 20, as shown in FIG. 5, a wall-like member 50 is provided at the front of the vehicle of the bulging portion 25, that is, at a portion where the board side main surface 21 and the board side upper surface 23 are not connected. A wall-like member attachment 31 is provided for attaching the. Note that each configuration of the wall-shaped member attachment portion 31 and an aspect of assembling the wall-shaped member 50 to the upper board 20 will be described later.

  As shown in FIG. 5, the surface material 40 has a shape following the bulging portion 25 and is attached to the surface 20 A of the board-side main surface 21 and the board-side upper surface 23 of the upper board 20. Specifically, the skin material 40 has a skin material side main surface portion 41 corresponding to the board side main surface portion 21 and a skin material side upper surface portion 43 corresponding to the board side upper surface portion 23. The skin material-side upper surface portion 43 is continuous with the upper end of the surface portion 41 so as to rise to the outside of the vehicle compartment. That is, the surface material 40 is formed so as to be bent along the vehicle vertical direction corresponding to the shape of the bulging portion 25 and to be substantially straight along the vehicle longitudinal direction. When a sheet-like member is bent along a first direction and formed straight along a second direction orthogonal to this, part of the sheet-like members may be overlapped, or a plurality of sheets may be used. There is no need to combine or form parts, and it is not necessary to stretch or form part of them. For this reason, the skin material 40 is formed in a shape following the bulging portion 25 so that wrinkles and irregularities are less likely to occur, and partial deformation or the like is less likely to occur by stretching and deforming a part thereof. ing.

  The skin material 40 is vacuum-formed before being attached to the upper board 20, and thus is shaped (shaped) in advance to a shape corresponding to the three-dimensional shape of the upper board 20. The shape which can be vacuum-formed is limited according to the material etc., and the height in the direction intersecting the closing direction is limited particularly when the surface material 40 is formed into a three-dimensional shape having a closed cross section. Ru. In the present embodiment, the surface material 40 has a substantially straight shape along the longitudinal direction of the vehicle, so that the cross section has a three-dimensional shape with an open shape, and the cross section has a three-dimensional shape with a closed shape. It is possible to increase the bulging height of the bulging portion 25 compared to the case of

  Then, the surface material 30 is attached to the surface of the trim board 11 so that the upper board 20 to which the adhesive is applied in advance is placed on the back surface of the formed surface material 40. The adhesive may be applied to the back surface of the surface material 30 instead of the surface 20 A of the upper board 20.

  As shown in FIG. 2 and FIG. 3, the skin material 40 is processed so that the terminal 45 located on the outer periphery of the skin material side main surface portion 41 and the skin material side upper surface portion 43 is not exposed to the vehicle interior side of the door trim 10 ing. Specifically, the terminal processing of the portion 45A of the terminal 45 of the covering material 40 located on the vehicle lower side is performed such that the upper end portion of the lower board 18 overlaps the inside of the passenger compartment. Further, of the terminals 45 of the covering material 40, the portion 45B located on the vehicle upper side (outside of the passenger compartment) is rolled up on the back surface side of the board-side upper surface portion 23, and terminal processing is performed. The portion 45C of the surface covering material 40 located on the front side of the vehicle is subjected to terminal processing so that the wall-shaped member 50 overlaps the inside (the front side of the vehicle) of the vehicle interior. In addition, in FIG. 2, since the part 45C of the terminal 45 is covered by the wall-shaped member 50, the external shape is shown with the dashed-two dotted line.

  Subsequently, each configuration of the wall-like member attachment portion 31 of the wall-like member 50 and the upper board 20 and an aspect of assembling the wall-like member 50 to the upper board 20 will be described.

  As shown in FIG. 2, the wall-shaped member 50 has a wall shape that closes an end 25 </ b> A of the bulging portion 25 in the vehicle longitudinal direction. A wall surface of the wall-like member 50 (a surface 51A of the main body 51 described later) on the vehicle interior side constitutes a side surface 10C of the door trim 10. By providing such a wall-like member 50, the door trim 10 can be provided from the gap between the end 25A of the bulging portion 25 and the inner panel even when the bulging height of the bulging portion 25 is high. The occurrence of a situation in which the inside of the vehicle door is viewed or foreign matter or the like intrudes into the inside of the vehicle door through the gap is suppressed.

  As shown in FIG. 4, the wall-like member 50 is provided on a plate-like main body 51 and a back surface (a surface on the outer side of the passenger compartment) 51 B of the main body 51, and is a locking portion engaged with the upper board 20. It is equipped with 52. The external shape of the main body 51 is surrounded by the end 25A of the bulging portion 25 on the front side of the vehicle, and the surface 51A of the main body 51 is a flat design surface. Further, the wall-like member 50 is provided with a positioning projection 53 projecting to the back side from the back surface 51B of the main body 51, and a portion of the outer peripheral end of the main body 51 disposed on the vehicle interior side, And a rib 54 extending along the portion 25A.

  The locking portion 52 is a locking claw that protrudes from the back surface 51B of the main body portion 51 to the back side. The plurality of locking portions 52 are distributed along the portion of the outer peripheral end of the main body 51 which is disposed on the vehicle interior side, that is, along the end 25 A of the bulging portion 25. Specifically, the locking portion 52 is adjacent to a locking portion 52A adjacent to the front end of the board-side upper surface 23 of the upper board 20 and a corner between the board-side upper surface 23 and the board-side main surface 21. The locking portion 52B and the locking portions 52C and 52D adjacent to the front end of the board-side main surface portion 21 are arranged in this order. Further, in the locking portion 52, the locking portion 52E is disposed substantially at the center of the main body portion 51.

  As shown in FIG. 5, the wall-like member attachment portion 31 has a planar shape having an opposing surface 32 facing the main body 51 as a whole. Further, in the wall-like member attachment portion 31, a locked portion 33 locked to the locking portion 52 at the opening edge of the wall-shaped member attachment portion 31 and a positioning hole 34 fitted to the positioning projection 53. And are provided.

  When assembling the wall-like member 50 to the upper board 20, first, the wall along the assembly path approaching from the end 25A (vehicle front side of the upper board 20) side of the bulging portion 25 Member 50 is brought closer to the upper board 20 to which the skin material 40 is attached. Then, while inserting the positioning projection 53 into the positioning hole 34, the position of the wall-shaped member 50 is aligned with the wall-shaped member mounting portion 31 of the upper board 20. Furthermore, the wall-like member 50 is moved along the assembly path so that the end 45 of the surface material 40 is wound on the back surface 20B side of the upper board 20, and the locking portion 52 engages with the locked portion 33. Stop. Then, the end 45 (portion 45C) of the surface material 40 is sandwiched between the side surface 51C of the wall member 50 and the back surface 20B of the upper board 20, and the rib 54 of the wall member 50 It will be in the state interposed between the wall-like member 50 and the wall-like member attaching part 31 of the upper board 20 so that it may be pressed toward the opposing surface 32 side (see FIG. 2). In this embodiment, since the wall-like member 50 is assembled in such a manner as to approach from the side of the upper board 20, it is possible to apply a tension to pull the end 45 of the surface material 40 outward. The end 45 of the surface material 40 is less likely to be generated, as compared with the case where the wall-like member is assembled so as to slide from the back surface side (vehicle compartment outer side) of the upper board to the end of the bulging portion. The generation of wrinkles and the like on the surface material 40 can be suppressed. In the above manner, the assembly of the wall-like member 50 to the upper board 20 is completed.

  Then, the effect in door trim 10 of this embodiment is explained. The door trim 10 of the present embodiment has a plate shape extending along the vehicle vertical direction and the vehicle longitudinal direction, and is bent along the vehicle vertical direction to form a substantially straight shape along the vehicle longitudinal direction. A trim board 11 having a bulging portion 25 bulging out to the indoor side, a skin material 40 covering a surface 20 A of the trim board 11 following the bulging portion 25, and an end portion of the bulging portion 25 in the vehicle longitudinal direction The wall-shaped member 50 has a wall-like shape for closing 25 A, and the wall-like member 50 assembled to the trim board 11 with the end 45 of the skin material 40 interposed.

  According to the present embodiment, since the wall-like member 50 is assembled to the trim board 11 with the end 45 of the skin material 40 interposed, the bulging height of the bulging portion 25 can be increased. The door trim 10 excellent in design can be realized. Specifically, in a configuration in which the skin material covers the end plate side of the bulging portion together with the plate surface of the trim board on the vehicle interior side, the skin material bulging when the bulging height of the bulging portion is high. By being shaped according to the three-dimensional shape formed by the protrusion and the wall surface, wrinkles are generated in the surface material, or when the surface material is vacuum-formed according to the three-dimensional shape in advance, the surface material is broken. And there is a risk that a gross may occur. On the other hand, in the present embodiment, since the skin material 40 does not cover the wall surface of the wall-like member 50, generation of wrinkles in the skin material 40 is suppressed regardless of the bulging height of the bulging portion 25. As a result, it is possible to suppress the occurrence of breakage or gloss on the surface material 40 when vacuum forming is performed in advance. For this reason, it is possible to suppress the occurrence of a situation in which the bulging height of the bulging portion 25 of the trim board 11 is limited due to the restriction in forming the skin material 40.

  Further, in the present embodiment, the wall-shaped member 50 is provided with a plurality of locking portions 52 locked to the trim board 11, and the plurality of locking portions 52 are provided at the end 25 A of the bulging portion 25. Distributed along the line. For this reason, by locking the wall-like member 50 to the trim board 11, the end 45 of the surface material 40 can be pressed along the end 25A of the bulging portion 25. Can be suppressed.

  Further, in the present embodiment, the trim board 11 is divided into an upper board 20 disposed on the upper side of the vehicle and a lower board 18 disposed on the lower side of the upper board 20, and the bulging portion 25 is The wall-like member 50 is formed at least on the front side of the vehicle in the upper board 20, and is disposed in front of the upper board 20 in the vehicle. For this reason, in the door trim 10, a novel design having the bulging portion 25 on the upper side and the front side of the vehicle easily visible to the passenger can be realized, and the wall-like member 50 not covered with the skin material 40 It can arrange in the vehicles front of trim board 11 which is hard to be recognized by people.
