Description

[Detailed Description of the Invention] This invention relates to an automobile trim used for edging the edges of an outer panel of a vehicle body.

Conventional automotive trims of this type are shown in Figures 1 and 3.
As shown in the figure, in a trim body 1 made of a polymeric material made of elongated rubber or synthetic resin and having a cross-sectional groove shape, a large number of narrow core materials 4 made by bending a metal plate into a groove shape are spaced apart. It is enclosed in a bag shape and fitted onto the edge 6 of the outer panel.

However, such conventional automotive trim is made of core material 4.
is enclosed in a bag shape without being adhered to the trim body 1, so the trim body 1 can expand and contract over its entire length without being constrained by the core material 4, and the amount of expansion and contraction is large, and the rigidity is not necessarily large. do not have.

This makes it difficult to attach the trim to the outer panels, etc., and since the installation of the tonome is usually done while applying force in the direction in which the trim extends using an air hammer, etc., it is inevitable that the trim will contract after installation due to stress relaxation in the polymer material. The trim tends to fall off, especially at the corners of the outer panels.

Further, there is a drawback that the shrinkage of the trim after installation is not constant, and installation causes wrinkles at corners with small bends.

This invention was made in order to overcome the drawbacks of conventional automobile trims as described above.

An embodiment of this invention will be described based on FIGS. 1 and 2.

1 is a trim body made of a long and narrow polymer material with a groove-shaped cross section.
Upward protrusions 3, 3 are provided on the inner walls of the end portions of both legs 2, 2, respectively.
is installed protrudingly.

4 is a core material, which is a narrow metal plate bent into a groove shape.

The core materials 4 are first arranged discontinuously in a row at intervals of 0.5 to 0.7 mm, and an adhesive substance 5 is applied to their inner and outer surfaces by applying an adhesive and drying it by a known method.

Next, the core material 4 in a row with the adhesive substance 5 attached passes through the base of the covering crosshead, and at this time, the core material 4 and the trim body 1 made of a polymeric material such as rubber are integrated with the adhesive substance 5 interposed therebetween. It will be adhesively molded.

That is, the automotive trim according to this invention 7 has a trim body 1 made of a molecular material that is elongated and has a groove shape in cross section, and in which a large number of narrow core members 4 made by bending a metal plate into a groove shape are arranged at intervals of C. Since the core material 4 and the trim body 1 are integrally bonded via the adhesive substance 5, the portion of the trim body 1 bonded to the core material 4 is restrained by the core material 4, B does not expand and contract, and the trim body 1 expands and contracts only within the interval C.

Therefore, the rigidity of the trim as a whole is increased compared to conventional trims, making installation easier, and since the amount of expansion and contraction is not large, there is no risk of the trim falling off when attached to a corner of the outer panel.
