DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pillar trim mounting structure for covering a vertically extending narrow pillar such as a front pillar of an automobile.

[0002]

2. Description of the Related Art A body of an automobile (vehicle) is provided with a pillar (support) between a window and a doorway for partitioning between the window and the entrance. As pillars called front pillars between the front window and the front door, pillars having a smaller width than other portions are used in order to secure a wide front view.

For example, as shown in FIG. 6, for example, a truck cab 1 (constituting a vehicle compartment) and the like, a front window 2 and left and right front doors (ports) 2a, 2
The front pillars 3, 3 which are as narrow as possible are provided between the front pillars a and a to secure a wide window surface.

Incidentally, such front pillars 3, 3
As shown in FIG. 7, a decorative member, for example, a pillar trim 4 made of, for example, a synthetic resin is attached to the inner surface (inside of the vehicle compartment).

Usually, this pillar trim 4 has a front windshield weather strip 5 (a weather strip for shielding the front window 2) and a door opening weather strip 6 (a weather strip for sealing the front door 2a) mounted on both sides. A clip 8 is provided on the inner side of the pillar body 7 of the pillar 3, that is, on the pillar inner panel 7 a of the pillar inner panel 7 a and the pillar outer panel 7 b joined in a hollow columnar shape so as to cover the panel surface between the weather strips 5 and 6. It is fixed with a fixing tool such as a screw (not shown).

[0006] The pillar trim 4 is a member that is exposed in the vehicle cabin, so that a particularly good appearance is required. Therefore, as the pillar trim 4 attached to the narrow pillar, a structure formed into a narrow plate having a substantially flat cross section as shown in FIG. 7 is usually used.

That is, when the pillar trim 4 is arranged so that the side edges of the pillar trim 4 overlap the upper surfaces of the weather strips 5 and 6, the side edges of the trim 4 face the cabin of the weather strips 5 and 6. Pairs well with surface.

[0008]

However, the rigidity of the pillar trim 4 is low due to the narrow plate shape. For this reason,
The pillar trim 4 may vibrate due to the running vibration of the vehicle.

In addition, since the side edges of the pillar trim 4 face the interior of the vehicle, the pillars are easily deformed by the solar radiation incident from the windows of the front window 2 and the front door 2a. May be disturbed.

Therefore, it has been considered to form a flange portion (bent portion) at the side edge portion of the pillar trim 4 to be bent toward the pillar inner panel. With this pillar trim, the rigidity of the trim itself is increased by the flange portion, and the side edge portion is arranged so as to abut against the upper surface of the weather strip, so that the appearance can be prevented from being deteriorated due to the deformation due to the temperature change. However, since the side portions of the pillar trim are arranged stepwise so as to protrude greatly from the surface of the weather strip due to the flange portion, it is not possible to secure a mounting posture that provides a sense of unity with the weather strip, and the appearance is greatly impaired.

Therefore, it has been studied to fit the pillar trim having the flange portion between the weather strips on both sides. However, this structure enables a mounting posture with a sense of unity in which the surface facing the interior of the pillar trim and the surface facing the interior of the weather strip are flush with each other. When the traveling vibration of the vehicle is applied due to weak regulation of the heading movement, the front end of the flange portion may come into contact with the door inner panel to generate abnormal noise.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a pillar trim which can be mounted on a pillar inner panel in a stable mounting posture without causing vibrations and abnormal noises. It is to provide a mounting structure.
