Japanese Patent Laid-Open No. 06-144125

  By the way, in order to improve the design of the interior of the vehicle, for example, at the position substantially the same as the straight line connecting the belt line of the door and the lower edge of the quarter window, the lower trim surface of the design surface portion of the upper trim and the lower trim It is desirable that the upper end surface of the design surface portion is in contact with each other.

  However, as in the structure described in Patent Document 1, when the lower trim is assembled so as to cover the lower portion of the upper trim from the vehicle interior side over the entire circumference, the upper trim and the lower trim are in contact with each other. A bulging part and a level | step difference will arise over the perimeter.

  Therefore, the divided surfaces, which are the surfaces formed at the divided positions in the upper trim and the lower trim, are configured to contact each other in the vertical direction or the vehicle front-rear direction, so that the design surface of the upper trim and the design surface of the lower trim face each other. It can be considered to be one.

  However, if the split surface of the upper trim and the split surface of the lower trim are configured to contact each other only in the vertical direction, the lower edge of the quarter window extends in the vehicle front-rear direction. It cannot be formed, and a matching portion must be provided at a position shifted upward from the lower edge. In addition, if the split surface of the upper trim and the split surface of the lower trim are configured to contact each other only in the vehicle front-rear direction, a step is formed on the surface facing the door, so that the design surface of the upper trim and the design surface of the lower trim are It is necessary to extend in the direction.

  On the other hand, when the alignment direction of the upper trim and the lower trim in the alignment portion is, for example, the vehicle front side is the vertical direction and the vehicle rear side is the vehicle front-rear direction, the alignment portion is shifted in the vertical direction or a step is formed. There is no need to do it. However, since the vertical direction and the vehicle front-rear direction are in a twisted relationship with each other, it is necessary to twist the mating portion or gradually change the mating direction while twisting the mating portion at a position where the mating directions interfere with each other. is there. For this reason, when mass-producing upper trim and lower trim by mold molding or the like, it is difficult to uniformly form a gap or a step between the upper trim and lower trim at the position of the twist due to manufacturing tolerances such as mold molding. is there. This invention is made | formed in view of such a point, and the place made into the objective is to make the improvement of the design property of pillar trim and securing of mass-productivity compatible by simple structure.

  In order to solve the above problems, in the present invention, an upper trim that covers a surface of the pillar panel on the vehicle interior side, a lower trim in which an upper end surface of the design surface portion is in contact with a lower end surface of the design surface portion of the upper trim, An opening formed at a position where the upper trim and the lower trim come into contact with each other, and is formed on the front side of the vehicle with respect to the opening through which the webbing of the seat belt device is inserted. A lower end surface of a design surface portion on the front side of the vehicle in the upper trim and a first mating portion in which an upper end surface of the design surface portion on the front side of the vehicle in the lower trim abuts each other; Second alignment in which the lower end surface of the design surface portion on the rear side of the vehicle in the upper trim and the upper end surface of the design surface portion on the rear side of the vehicle in the lower trim contact each other The lower end surface of the design surface portion on the front side of the vehicle in the upper trim and the upper end surface of the design surface portion on the front side of the vehicle in the lower trim are configured to contact each other in the vertical direction at the first mating portion. On the other hand, the lower end surface of the design surface portion on the rear side of the vehicle in the upper trim and the upper end surface of the design surface portion on the rear side of the vehicle in the lower trim are all in contact with each other in the vehicle front-rear direction in the second mating portion. Alternatively, a part is abutted in the vehicle width direction and the remaining part is abutted in the vehicle front-rear direction, and the alignment direction of the upper trim and the lower trim is the first alignment part via the opening. From the alignment direction to the alignment direction of the second alignment portion.

  According to this configuration, the lower end surface of the design surface portion on the front side of the vehicle in the upper trim and the upper end surface of the design surface portion on the front side of the vehicle in the lower trim contact each other in the vertical direction by the first mating portion, while the rear side of the vehicle in the upper trim The lower end surface of the design surface portion and the upper end surface of the design surface portion on the vehicle rear side in the lower trim are all in contact with each other in the vehicle front-rear direction by the second mating portion, or a part is in contact in the vehicle width direction and the remaining portion is Contact in the longitudinal direction of the vehicle. Thus, on both sides of the vehicle front side and the vehicle rear side, the above-mentioned mating portion can be adjusted without shifting the mating portion of the upper trim and the lower trim vertically from the belt line of the door or providing a step in the mating portion. It can be formed on a straight line connecting the belt line of the door and the lower edge of the quarter window.

  Further, the opening is formed at a position where the upper trim and the lower trim contact each other, and the alignment direction of the upper trim and the lower trim is changed from the alignment direction of the first alignment portion through the opening to the second alignment. It is comprised so that it can switch to the alignment direction of a part. That is, at the portion where the upper trim and the lower trim abut, the dividing surfaces formed on the lower end surface of the design surface portion of the upper trim and the upper end surface of the design surface portion of the lower trim are changed from the vehicle front side to the vehicle rear side in the upper trim and lower trim. For example, the upper trim dividing surface extends from the vehicle front end at the lower end of the upper trim to the vehicle front end of the opening, while the lower trim dividing surface extends to the upper end of the lower trim. Extending from the vehicle front side end portion of the opening to the vehicle front side end portion of the opening, and forming a dividing surface in a region corresponding to the opening portion of the lower end portion of the upper trim and the upper end portion of the lower trim, the vehicle rear side end of the opening portion The dividing surface on the vehicle rear side of the upper trim and the lower trim, in which the alignment direction is switched, is formed from the section. Accordingly, at the position where the alignment direction of the upper trim and the lower trim is switched from the vertical direction that is the alignment direction of the first alignment portion to the vehicle front-rear direction or the vehicle width direction that is the alignment direction of the second alignment portion. The alignment direction can be switched without twisting. Therefore, it is possible to prevent the appearance of the interior of the vehicle from being deteriorated by forming an excessive gap or step between the upper trim and the lower trim due to the twist, and to improve the design of the interior of the vehicle. In addition, since the twist does not occur, even in a manufacturing method such as mold molding that causes manufacturing tolerances, gaps and steps can be formed uniformly between the upper trim and the lower trim. Mass productivity can be ensured while preventing the design of the interior of the vehicle from deteriorating.

  In one embodiment of the interior structure of the vehicle, the design surface on the vehicle front side of the upper trim and the design surface on the vehicle front side of the lower trim form a surface that is continuous in the vertical direction in the first mating portion. The design surface on the vehicle rear side of the upper trim and the design surface on the vehicle rear side of the lower trim are configured to form a continuous surface in the vehicle front-rear direction at the second mating portion.

  According to this configuration, generally, the design surface on the vehicle front side of the upper trim and the design surface on the vehicle front side of the lower trim that face the vehicle interior side of the pillar panel facing the door are vertically aligned at the first mating portion. Therefore, the design surface on the vehicle front side of the upper trim and the design surface on the vehicle front side of the lower trim can be flush with each other in the vertical direction. In general, the design surface on the vehicle rear side of the upper trim and the design surface on the vehicle rear side of the lower trim that cover the vehicle interior side rear surface of the pillar panel in which the quarter window is provided are arranged in the vehicle longitudinal direction at the second mating portion. Therefore, the design surface on the vehicle rear side of the upper trim and the design surface on the vehicle rear side of the lower trim can be flush with each other in the vehicle front-rear direction. As a result, there is no step at the first and second mating portions, so that the design of the interior of the vehicle can be further improved.

  In the interior structure of the vehicle, a door is disposed on the vehicle front side of the upper trim and the lower trim, and the first and second mating portions are substantially the same as the height position where the belt line of the door is formed. It is desirable to be formed at a height position.

  That is, in the first and second mating portions, a split line is formed by the abutment surface of the upper trim split surface and the lower trim split surface, but the first and second mating portions are connected to the door belt line. If formed at substantially the same height, the dividing line on the vehicle front side and the dividing line on the vehicle rear side are formed at substantially the same height as the belt line of the door. As a result, in the vehicle side view, the dividing line on the front side of the vehicle, the dividing line on the rear side of the vehicle, the belt line of the door, and the lower edge of the quarter window are aligned in a substantially straight line, further improving the design of the interior of the vehicle. Can be improved.

  In the interior structure of the vehicle, the upper trim includes a design surface portion on the vehicle front side, a design surface portion on the vehicle rear side, an end portion on the vehicle interior side of the design surface portion on the vehicle front side, and the vehicle rear side in the upper trim. A cross-section substantially C-shaped inflating toward the vehicle interior side so as to cover the vehicle interior side surface of the pillar panel with a design surface portion in the vehicle width direction coupled to the vehicle interior side end of the design surface portion The opening is formed from the position of the vehicle front side end portion of the design surface portion on the inner side in the vehicle width direction or the intermediate position in the vehicle front-rear direction of the design surface portion on the inner side in the vehicle width direction in the upper trim. It is desirable to extend to the position of the vehicle rear side end portion of the design surface portion on the inner side in the width direction.

  That is, in the upper trim formed in an approximately C-shaped transverse section, the opening is from the vehicle front side end portion of the design surface portion inside the vehicle width direction or the vehicle front-rear direction intermediate position of the design surface portion inside the vehicle width direction. While extending to the position of the vehicle rear side end portion of the design surface portion on the inner side in the vehicle width direction, an opening portion or a first mating portion is formed on the design surface portion on the inner side in the vehicle width direction of the upper trim and the lower trim, The alignment in the vehicle width direction in the second alignment portion is not formed. That is, since it is not necessary to consider the alignment in the vehicle width direction, the structure around the second alignment portion of the upper trim and the lower trim is simplified, and the manufacturing can be simplified.

  In the configuration in which the opening extends to the position of the vehicle rear side end portion of the design surface portion on the inner side in the vehicle width direction of the upper trim, the upper trim corresponds to the design surface portion on the inner side in the vehicle width direction on the upper trim. The region in the vertical direction is a bulging region in which the upper and lower intermediate portions bulge to the vehicle interior side from the upper end of the lower trim in the region and the lower end of the lower trim in the region, and the opening is the bulging It is desirable that an upper end portion of the lower trim in the region is cut away to form a gap formed when the upper trim and the lower trim come into contact with each other.

  That is, a gap formed by cutting out the lower end portion of the design surface portion on the inner side in the vehicle width direction in the upper trim, or a portion of the lower portion of the design surface portion on the inner side in the vehicle width direction in the upper trim is recessed in the vehicle width direction outside. If the opening is formed by the formed gap, the opening extends to the position of the vehicle rear side end portion of the design surface portion on the inner side in the vehicle width direction of the upper trim. A ridge line formed between the design surface portion and the design surface portion on the vehicle rear side of the upper trim is interrupted by the opening. On the other hand, in the region corresponding to the design surface portion on the inner side in the vehicle width direction of the upper trim in the upper portion of the lower trim, the vertical middle portion in the region is defined as the upper end portion of the lower trim in the region and the lower end portion of the lower trim in the region. If the opening is formed by a gap formed by bulging to the vehicle interior side and the upper end portion in the region is notched, the opening is a design surface portion on the inner side in the vehicle width direction of the upper trim. Even if it extends to the rear end of the vehicle, the ridgeline is not interrupted by the opening, so that the design of the interior of the vehicle can be further improved. Moreover, since the line of the vehicle rear side edge part of an opening part and the line of the upper end of the design surface of the vehicle rear side in a lower trim can be made continuous, the alignment direction of the 1st alignment part via an opening part Thus, switching from the vertical direction to the vehicle front-rear direction, or the vehicle front-rear direction and the vehicle width direction, which is the alignment direction of the second alignment portion, becomes smooth, and the design of the interior of the vehicle can be improved.

  In the interior structure of the vehicle, the lower trim includes a fixing portion for fixing the lower trim to the upper trim in the vehicle width direction, and the second mating portion is outward in the vehicle width direction toward the vehicle rear side. It is desirable to be inclined.

  That is, in the configuration in which the lower trim is assembled to the upper trim in the vertical direction, it is difficult to align the position of the lower trim with respect to the upper trim in the vehicle front-rear direction, so when assembling, the design surface portion on the vehicle rear side of the upper trim and the vehicle rear side of the lower trim The design surface part may collide and the periphery of the second mating part may be damaged. On the other hand, when the lower trim is assembled to the upper trim in the vehicle front-rear direction, it is difficult to align the lower trim in the vertical direction with respect to the upper trim. There is a possibility that the periphery of the first mating portion may be damaged by colliding with the surface portion. Therefore, by allowing the lower trim to be assembled to the upper trim from the vehicle interior side in the vehicle width direction, the position of the lower trim in the vertical direction and the position in the vehicle longitudinal direction can be easily matched. As a result, when the lower trim is assembled to the upper trim, the design surface portion of the upper trim and the design surface portion of the lower trim collide with each other around the first and second mating portions, and the periphery of the first and second mating portions. Can be prevented from being damaged.

  In addition, since the second mating portion is inclined outward in the vehicle width direction toward the rear side of the vehicle, when the lower trim is assembled to the upper trim from the vehicle interior side, the upper trim is separated from the split surface on the rear side of the vehicle. As a result, it becomes easier to bring the split surface on the vehicle rear side of the lower trim into contact with each other, so that the periphery of the split surface can be prevented from being damaged.

  As described above, the interior structure of the vehicle according to the present invention is an opening formed at a position where the upper trim and the lower trim come into contact with each other, and is closer to the vehicle front side than the opening through which the webbing of the seat belt device is inserted. A first mating portion formed between the lower end surface of the design surface portion on the front side of the vehicle in the upper trim and the upper end surface of the design surface portion on the front side of the vehicle in the lower trim; and formed on the rear side of the vehicle from the opening portion. A lower end surface of the design surface portion on the front side of the vehicle in the upper trim, further comprising a second mating portion in which a lower end surface of the design surface portion on the rear side of the vehicle in the trim and an upper end surface of the design surface portion on the rear side of the vehicle in the lower trim contact each other And the upper end surface of the design surface portion on the front side of the vehicle in the lower trim are configured to contact each other in the vertical direction in the first mating portion, The lower end surface of the design surface portion on the rear side of the vehicle in the upper trim and the upper end surface of the design surface portion on the rear side of the vehicle in the lower trim are all in contact with each other in the vehicle longitudinal direction at the second mating portion, or a part thereof And the remaining portion abuts in the vehicle front-rear direction. The alignment direction of the upper trim and the lower trim is from the alignment direction of the first alignment portion through the opening portion of the second alignment portion. Since it is switched to the alignment direction, the twist at the position where the alignment direction of the first alignment portion and the alignment direction of the second alignment portion are switched is eliminated, and the first alignment portion, the second alignment portion, and the door The belt line and the lower edge of the quarter window can be arranged on a substantially straight line. As a result, it is possible to achieve both improvement in design properties and securing mass productivity.
