A peripheral wall portion, and a second mating surface formed at a terminal of the inclined surface portion so as to be parallel to the mating surface, the mating surface and the second mating surface; The top section of the upper cross section of the door trim is formed by aligning the trim board and the cover so that the inclined surface portion and the peripheral wall portion are flush with each other in a state of being opposed to each other. It is characterized by being.

  With this configuration, the trim board is formed at the end of the trim board on the vehicle upper side, and is inclined toward the vehicle interior side so as to be separated from the door glass surface toward the vehicle upper side. A mating surface that is formed on the design surface side, intersects with the general surface portion on the opposite design surface side, and recedes toward the vehicle lower side toward the vehicle interior side in the vehicle width direction, and continues from the mating surface to the vehicle upper side. And a second mating surface formed so as to be parallel to the mating surface at the end of the inclined surface portion, and the mating surface and the second mating surface are The top section of the upper cross section of the door trim is formed by aligning the trim board and the cover so that the inclined surface portion and the peripheral wall portion are flush with each other in a state of being opposed to each other. Ah Therefore, the cross-sectional area of the door trim is reduced from the inclined surface portion to the top portion, the feeling of pressure on the vehicle interior space is suppressed, and the inclined surface portion is aligned with the peripheral wall portion of the cover, thereby providing a design. In addition to being ensured, even when the inclined surface portion is displaced so as to fall toward the vehicle interior side, the degree of the gap between the cover terminal portion is reduced by the mating surface and the second mating surface. Can be suppressed. That is, it is possible to provide a vehicle door trim that has good appearance and excellent design.

  Here, preferably, the mating surface and the second mating surface are brought into contact with each other, and the trim board is directed toward the vehicle interior side in the vehicle width direction in the vicinity of the contact portion. It is provided with a locking claw that extends, and the trim board and its cover are fixed by locking the locking claw to a locked portion provided on the back side of the cover. is there. In this way, a force that causes the inclined surface portion to move outward from the passenger compartment is applied at the contact portion, and therefore, for example, there is no need to provide a rib for preventing the inclined surface portion from falling down, and the more reliable. It is possible to suppress a decrease in appearance.

It is the schematic which shows the vehicle door trim to which this invention is applied suitably, and is a front view which shows the design surface side, ie, the vehicle interior side.

  As shown in FIG. 2, at least the design surface side of the cover 14 is covered with a skin material 26. As the skin material 26, for example, a vinyl chloride sheet (vinyl chloride film) is preferably used, but a natural material such as wool or cowhide may be used. In FIGS. 2 to 5, the thickness does not necessarily correspond to the actual thickness dimension in order to make it easy to understand the presence of the skin material 26 (the same applies in the following description). Between the trim board 12 and the door glass 28, an inner weather strip 30 made of sponge rubber or the like with a synthetic rubber coating is provided to prevent intrusion of wind and rain, dust and the like. That is, at the top portion (the vehicle upper side end portion) 32 of the vehicle door trim 10 of the present embodiment, at least the upper edge of the door trim 10 at the portion shown in FIG. The upper end of the cover 14 is the vehicle upper side.

  FIG. 3 is an enlarged view showing a part of FIG. 2, that is, a configuration near the top portion 32 of the vehicle door trim 10 of the present embodiment. As shown in FIG. 3, the end of the trim board 12 on the vehicle upper side is separated from a vehicle interior side surface (hereinafter referred to as a door glass surface) 28a of the door glass 28 toward the vehicle upper side. An inclined surface portion 34 is formed to be inclined toward the vehicle interior side. The inclined surface portion 34 is configured to be retracted from the door glass surface 28a toward the vehicle upper side. In other words, an inclined surface portion 34 that is inclined (forwardly inclined) toward the vehicle interior side with respect to the door glass surface 28a is provided at an end of the trim board 12 on the vehicle upper side. With such a configuration, in the top portion 32 of the vehicle door trim 10 of the present embodiment, the horizontal sectional area of the door trim 10 as a whole is gradually reduced from the lower end to the upper end (the upper end of the door trim 10) of the inclined surface portion 34.

Is provided with a hook-like projection. Further, the locked portion 24 is configured to include a fitting hole for fitting the hook-shaped protrusion, and the locking claw 22 faces the vehicle inward side with respect to the locked portion 24. Then, the hooking projection is fitted into the fitting hole so that the locking claw 22 and the locked portion 24 are locked with each other.

  FIG. 4 is an enlarged view showing the vicinity of the contact portion between the trim board 12 and the cover 14 at the top 32 of the vehicle door trim 10 according to the present embodiment. As shown in FIG. 4, the cover 14 terminal, that is, the counter-design surface side of the cover 14 on the upper side of the vehicle intersects with the general surface portion 36 on the counter-design surface side, and in the vehicle width direction. A mating surface 38 is formed that recedes (inclines) toward the vehicle lower side toward the vehicle side. In other words, the general surface portion 36 is an inner peripheral surface of the cover 14 around the top portion 32 of the vehicle door trim 10. Further, the upper end portion of the trim board 12 (near the upper end portion of the inclined surface portion 34) is configured to be substantially parallel to the mating surface 38 formed on the cover 14 when the cover 14 is attached. Two mating surfaces 40 are formed. In other words, the mating surface 38 and the second mating surface 40 are configured to be in surface contact with each other during mounting. When the cover 14 is attached to the trim board 12, the mating surface 38 and the second mating surface 40 are mutually connected via the skin material 26 that covers the cover 14 as shown in FIG. 4. Can be brought into contact (surface contact).

  As shown in FIG. 4, the mating surface 38 is formed so as to intersect with a general surface portion 36 (surface indicated by a broken line in FIG. 4) that is an inner peripheral surface of the cover 14 on the counter-design surface side. The vehicle is inclined so as to recede (lower) toward the vehicle lower side as it goes toward the vehicle inner side in the vehicle width direction, that is, ascend toward the vehicle outer side in the vehicle width direction. In other words, the mating surface 38 is connected at a predetermined angle (preferably an obtuse angle) to the general surface portion 36 adjacent to the vehicle interior side. Similarly, the second mating surface 40 is inclined so as to recede toward the vehicle lower side as it goes toward the vehicle inner side in the vehicle width direction, that is, ascend toward the vehicle outer side in the vehicle width direction. It has been. Further, as shown in FIG. 4, the mating surface 38 is preferably provided so as to extend further toward the vehicle inward side by a predetermined dimension than the second mating surface 40. In other words, the mating surface 38 is preferably provided with an excess of a predetermined dimension on the vehicle inward side of the portion where the second mating surface 40 abuts when the cover 14 is attached to the trim board 12. It is configured.

  As shown in FIG. 4, the cover 14 includes a peripheral wall 42 that continues from the mating surface 38 to the vehicle upper side. In the vehicle door trim 10 of the present embodiment, in the state where the cover 14 is attached (attached) to the trim board 12, as shown by a one-dot chain line in FIG. The trim board 12 and the cover 14 are aligned so that they are substantially flush with each other. Here, in FIG. 4, the inclined surface portion 34 and the surface of the skin material 26 corresponding to the peripheral wall portion 42 are shown to be flush with each other. Since the thickness dimension is different from the actual thickness and is shown to be thicker than the actual thickness in FIG. 4, the inclined surface portion 34 and the peripheral wall portion 42 are substantially flush with each other. With such a configuration, the design of the mating portion (joint portion) between the trim board 12 and the cover 14 is ensured.

  4, the mating portion of the trim board 12 and the cover 14 is positioned above the upper end of the inner weather strip 30 as described above with reference to FIG. Since the inclined surface portion 34 and the peripheral wall portion 42 are substantially flush, the appearance from the outside of the vehicle is particularly problematic. FIG. 6 is a diagram illustrating the configuration of the top of a conventional vehicle door trim for comparison with the present invention. In the example shown in FIG. 6, the flat portion 46 formed on the counter-design surface side of the terminal of the cover 14 and the flat portion 48 formed on the upper end portion of the trim board 12 are brought into contact with each other, whereby the top portion 50 is formed. Although configured, the flat portions 46 and 48 do not retract toward the vehicle lower side toward the vehicle interior side in the vehicle width direction, and are both substantially horizontal (parallel to the horizontal plane). In such a configuration, as shown by a broken line in FIG. 6, when the wall portion 34 a corresponding to the inclined surface portion 34 is displaced so as to turn and fall down from the corner portion 44 as a base point due to deformation or the like, There is a possibility that the gap between the flat portions 46 and 48, that is, the gap between the cover 14 and the trim board 12 becomes large, and the design property is deteriorated.

  On the other hand, according to the vehicle door trim 10 of the present embodiment described above with reference to FIGS. 2 to 4 and the like, as compared with the conventional configuration shown in FIG. Since the trim board 12 and the cover 14 are brought into contact with each other by the mating surface 38 and the second mating surface 40 configured to recede to the side, the wall portion 34a is deformed or the like, so that the corner portion Even when it is displaced so as to turn inward from the vehicle with reference to 44, the mating surface 38 intersects with the general surface portion 36 on the design surface side on the counter-design surface side of the cover 14. By providing, the mating surface 38 is sufficient with respect to the vehicle width direction so as to correspond to the displacement direction of the second mating surface 40 (to approach the tangential direction of the rotation locus of the second mating surface 40). Because it can be tilted The degree of the gap between the cover 14 and the trim board 12, that is, between the mating surface 38 and the second mating surface 40 can be suppressed small, and the desired design can be achieved even at a position that is easily visible from the outside of the vehicle. It is possible to effectively suppress a decrease in the appearance of the mating portion while securing the property. Further, in addition to such a configuration, the locking direction of the locking claw 22 provided in the vicinity of the contact portion between the mating surface 38 and the second mating surface 40, that is, the locked state formed on the cover 14. Since the fitting direction with respect to the portion 24 is substantially parallel to the vehicle width direction, a force that causes the wall portion 34a corresponding to the inclined surface portion 34 in the second mating surface 40 to act outward of the vehicle is applied. For example, in order to prevent the wall portion 34a from falling down, the wall portion 34a can be preferably prevented from falling without providing a rib in the corner portion 44, and at the same time, the appearance of the inclined surface portion 34 on the design surface side can be reduced. The decrease can also be suitably suppressed.

  Next, another preferred embodiment of the present invention will be described in detail with reference to the drawings. In the following description, portions common to the embodiments are denoted by common reference numerals and description thereof is omitted.

  FIG. 5 is a view for explaining a modification of the vehicle door trim of the present invention. In the configuration shown in FIG. 5, compared to the configuration described above with reference to FIGS. 2 to 4, the skin material 26 that covers the cover 14 is not provided, and the mating surface 38 formed on the cover 14. And the second mating surface 40 formed on the trim board 12 are opposed to each other with a slight gap d that cannot be visually recognized unless they are sufficiently close to each other. Even in such a configuration, the gap between the cover 14 and the trim board 12 can be reduced by the mating surface 38 and the second mating surface 40. Further, even if the mating surface 38 and the second mating surface 40 are brought into contact with each other, the wall corresponding to the inclined surface portion 34 in the second mating surface 40 as in the above embodiment. A force that causes the portion 34a to move outward of the vehicle is applied, and it is possible to suitably suppress the extreme falling of the wall portion 34a, and it is also preferable to suppress a decrease in the appearance of the inclined surface portion 34 on the design surface side. be able to.

  Thus, according to the present embodiment, the inclined surface portion that is formed on the vehicle upper side end portion of the trim board 12 and that is inclined toward the vehicle interior side so as to be separated from the door glass surface 28a toward the vehicle upper side. 34 and a mating surface 38 that is formed on the counter-design surface side of the cover 14 terminal, intersects with the general surface portion 36 on the counter-design surface side, and recedes toward the vehicle lower side in the vehicle width direction. A peripheral wall portion 42 continuous from the mating surface 38 to the vehicle upper side, and a second mating surface 40 formed at the end of the inclined surface portion 34 so as to be parallel to the mating surface 38. In the state where the mating surface 38 and the second mating surface 40 are opposed to each other, the inclined board portion 34 and the peripheral wall portion 42 are flush with each other so that the trim board 12 and the peripheral wall portion 42 are flush with each other. Cover 14 and By being combined, the top section 32 of the upper cross section of the door trim 10 is formed, so that the sectional area of the door trim 10 decreases from the inclined surface section 34 to the top section 32, and the feeling of pressure on the vehicle interior space is suppressed. In addition to the fact that the inclined surface portion 34 is flush with the peripheral wall portion 42 of the cover 14 to ensure design, the inclined surface portion 34 is displaced so as to fall toward the vehicle interior side. Even in this case, the degree of the gap between the end portion of the cover 14 can be reduced by the mating surface 38 and the second mating surface 40. That is, it is possible to provide the vehicle door trim 10 that has a good appearance and an excellent design.

  Further, the mating surface 38 and the second mating surface 40 are brought into contact with each other, and the trim board 12 extends toward the vehicle interior side in the vehicle width direction in the vicinity of the contact portion. A locking claw 22 is provided, and the trim board 12 and the cover 14 are fixed by locking the locking claw 22 to a locked portion 24 provided on the back side of the cover 14. Therefore, a force that causes the inclined surface portion 34 to move outward in the passenger compartment is applied at the contact portion, and therefore, for example, it is not necessary to provide a rib for preventing the inclined surface portion 34 from falling down. Thus, it is possible to more reliably suppress a decrease in appearance.

  The preferred embodiments of the present invention have been described in detail with reference to the drawings. However, the present invention is not limited to these embodiments, and various modifications can be made without departing from the spirit of the present invention. Is.
