Description

[Detailed explanation of the invention] This invention molds a pillar garnish into one body to match the shapes of the roof side pillar and the tilting pillar, and has multiple reinforcing ribs on the back side of the bent part of this pillar garnish. This relates to a pillar garnish which is characterized in that it is provided with a pillar garnish.

In the conventional pillar garnish, a roof side pillar garnish 21 is fixed to the roof side pillar with a clip or the like, as shown in FIG. Since the pillar garnish 22 is fixed with a clip or the like, the roof side pillar garnish 21 and the front pillar garnish 22 have to be molded separately, which requires twice the effort and reduces productivity. Along with the disadvantages of poor roof side pillar garnish 21 and front pillar garnish 22.
There is a disadvantage that the joint portion 23 is formed on the surface and looks unsightly.

To eliminate these drawbacks, it would be possible to mold a pillar garnish that covers both roof side pillars into one piece using synthetic resin to match the shape of the roof side pillar and a pillar that slopes at a predetermined angle. In the formed pillar garnish, when each pillar is assembled and welded, variations occur in the predetermined angle α, so when it is fixed to each pillar, torsional force acts on the bent part of the pillar garnish, causing stress. is concentrated, resulting in twisting and deformation, and especially in a high-temperature atmosphere, the upper side of the bent portion will extend more than the lower side, and the pillar garnish itself will elongate and become significantly deformed.

This idea eliminates the above-mentioned drawbacks of conventional pillar garnishes, and also includes a pillar garnish made of synthetic resin that covers both roof side pillars and a pillar that slopes at a predetermined angle. The purpose is to disperse stress and prevent the pillar garnish from deforming even when molded.

Next, an embodiment illustrating the pillar garnish of this invention will be described.

It consists of a roof side pillar cover part 1 that covers both pillars according to the shape of a roof side pillar and a pillar that is inclined at a predetermined angle α with respect to the roof side pillar, a tilted pillar cover part 2, and a bent part 3. The pillar garnish 4 is molded into one piece from synthetic resin.

Two reinforcing ribs 5, 5 are provided on the back surface of the bent portion 3 of the pillar garnish 4 at a distance from each other approximately at the center of the bent portion 3, and the two reinforcing ribs 5, 5 are crossed at both ends. The bent portion 3 has a triangular shape extending from the center to both sides. These reinforcing ribs 5, 5 are pillars that have a high central part, zero height at both ends, and gradually lower from the central part to both ends so that the upper surfaces 6, 6 become almost arc-shaped. This is Garnishee 4.

In the pillar garnish 4 of this embodiment,
A roof side pillar cover part 1 and a pillar cover part 2 corresponding to, for example, a front pillar garnish.
Since the pillar garnish 4 is molded into one body, when used by fixing the pillar garnish 4 to the pillar with a clip, there are no joints on the surface of the pillar garnish 4, and the appearance is good and the bent parts of the pillar garnish 4 are As mentioned above, there are reinforcing ribs 5 with special shapes on the back side of 3.
Since the reinforcing ribs 5, 5 are provided at intervals in the center and cross each other at both ends, even if a torsional force is applied to the bent portion of the pillar garnish, the reinforcing ribs 5, 5 act on each other. The stress is dispersed and the pillar garnish does not deform, and furthermore, the pillar garnish does not deform even in a high temperature atmosphere.

The pillar garnish shown in FIGS. 4 and 5 is another embodiment of the roof side pillar cover part 1.
1, the tilting pillar cover part 12, and the bent part 1
A pillar garnish 14 having 3 and 3 is integrally molded from synthetic resin.

Two reinforcing ribs 15, 15 are provided on the back surface of the bent portion 13 of this pillar garnish 14 at an interval at approximately the center of the bent portion 13, and these two reinforcing ribs 15, 15 extend from the center to both ends. The reinforcing ribs 15, 15 have a rounded shape that bulges outward over the entire length, and intersect at both ends. The reinforcing ribs 15, 15 have a height at the center, zero height at both ends, and a pillar garnish 14 in which the upper surfaces 16, 16 are gradually lowered linearly from the center to both ends. It is.

FIG. 6 shows another embodiment of the reinforcing rib 25, in which both ends of the reinforcing rib 25 are made slightly higher.

In the above embodiment, two reinforcing ribs are provided, but if the width of the pillar garnish is large, three or more reinforcing ribs may be provided. In this case as well, the reinforcing ribs are provided at intervals in the center, and intersect with each other at both ends.

The pillar garnish of this invention is molded into one body instead of the conventional two-part body joined with a hard-to-see joint, so there are no joints on the surface of the pillar garnish, and it looks good and can be assembled at once. Since one pillar garnish can be made, the productivity of the pillar garnish can be improved.

The pillar garnish of this invention has multiple reinforcing ribs with a special shape as mentioned above on the back of the bent part to improve torsional rigidity, so even if the bent part of the pillar garnish is subjected to torsional force, it will be reinforced. Stress is dispersed from the low points at the ends of the ribs to the high points at the center, and the multiple reinforcing ribs interact with each other to prevent deformation of the pillar garnish. This has the effect of preventing the needle from deforming.

Furthermore, in the pillar garnish of this invention, the height of the reinforcing ribs provided on the back of the bent part is gradually lowered from the center to both ends, so that the height of the reinforcing ribs on the back side of the pillar garnish is gradually lowered from the center to both ends. An effect is that sink marks (dents formed on the surface of the synthetic resin) caused by providing reinforcing ribs on the surface of the bent portion are reduced by the lowered height.
