Description

  The present invention relates to an opening trim structure for a sliding door vehicle.

  As a structure of a door of an automobile, a slide door that is opened and closed by sliding the door is conventionally known. Generally, there are three sliding doors: an upper rail located near the end of the roof in the vehicle width direction, a center rail located near the center of the vehicle side surface in the vehicle vertical direction, and a lower rail located near the side sill below the vehicle body. The rail can be slid to open and close.

  The sliding door includes an outer rail type sliding door and an inner rail type sliding door. In the outer rail type sliding door, three rails for sliding the door are provided on the outer plate of the vehicle body. Moreover, the rail for sliding an inner rail type | mold slide door is provided in the inner side of the vehicle body. For this reason, the inner rail type sliding door has an advantage that it looks good because the rail is hidden compared to the outer rail type sliding door.

  In particular, when the sliding door is employed in a small vehicle or a vehicle with a low vehicle height, the outer rail type sliding door has a poor appearance because the upper rail comes close to the user's viewpoint. For this reason, an inner rail type sliding door is employed to prevent the upper rail from entering the user's field of view, thereby improving the appearance.

  When an inner rail type sliding door is used, an opening trim is installed to improve the appearance of the flange near the upper rail and prevent injury at the flange end. FIG. 7 is a perspective view of an opening trim structure of a conventional inner rail type sliding door. In addition, the structure of the door opening part for passenger | crew getting on / off where a rear door is installed is shown here. As shown in FIG. 7, the side roof rail 32 extends between the upper part of the center pillar panel 30 and the upper part of the rear pillar panel 31. An upper rail (not shown) is disposed behind the side roof rail 32 (in the vehicle width direction), and is hidden by the side roof rail 32. In addition, a side roof rail cover 33 that covers the lower side of the upper rail and partitions the compartment side extends below the side roof rail between the upper portion of the center pillar panel 30 and the upper portion of the rear pillar panel 31.

  A rear door opening trim upper 34 is attached to the flange portion of the side roof rail 32. A rear door opening trim 35 is attached to the flange portion of the side roof rail cover 33 from the center pillar panel 30 to the rear pillar panel 31. An example of such a structure is disclosed in Patent Document 1 below.
