JPS592953A - Connecting structure of interior trimming parts of motor car - Google Patents

Abstract

PURPOSE:To strengthen rigidity and eliminate undulation, by a method wherein the edge of one side of interior trimming parts is covered with a lip of a welt and a stepped part is formed by bending the tip part of the interior trimming parts of a car room far inner than the welt in the reverse side of a sill on which the welt is secured. CONSTITUTION:The edge 2A of a dashboard side finisher is covered with a lip 3b of a welt 3A. A stepped part 2a which is bent in the reverse direction of a sill B in relation to the surface to which the lip 3b is touched is formed on a part positioning far inner than the lip 3b of a welt 3A inside a car room and a height h2 is made to increase. As for the edge 2A of the dashboard side finisher, both a cross-sectional primary coefficient and a cross-sectional secondary coefficient are large, it is stabilized and does not deform against a tortional and a bending loads.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an interior repair structure for an automobile, and more particularly to a joint structure between a finisher terminal and other interior parts.

Conventionally, the finisher terminal of an automobile has been joined to other interior parts, for example, as shown in FIGS. 1 and 2. That is, FIGS. 1 and 2 show the dash side finisher terminal part, and the terminal 2 of the dash side finisher 2 is fixed to the inner surface of the base of the front pillar A with the mounting screw l.
A, front pillar and sill B flanges a, b
It extends above the sill B along the indoor surface of the welt 3 fixed to the sill B, and is joined together with the end of the welt 3 to the sparkling plate 4 in an overlapping manner.

By the way, a floor mat 5 or a carpet is laid between the dash side finisher 2 and the sparkling plate 4 as described above and the sill B, but the dash side finisher terminal 2A is quite far from the dash side finisher body. Since it extends a distance and has a small section modulus, it is pushed up by floor mats 5, etc., and the first
It deforms as shown in the figure, and the floor mat 5 etc. becomes wavy at the joint β, and the interior parts become misaligned, making it impossible to obtain a good-looking finish. This is noticeable when the Kirakiking plate 4 is made of an extruded material with a uniform cross section and a relatively small section modulus.

In order to prevent the floor mat 5 etc. from waving as described above, as shown in the third figure, the lip 3 provided on the welt 3A
Although it is conceivable that the two dash side finisher terminals can be held down by the dash side finisher terminal 2, since the lip 3b has low rigidity and the floor mat 5 is thick, the height hl in the cross section of the dash side finisher terminal 2 becomes small.
The primary section modulus of the loop portion becomes small, and it is still not possible to prevent waviness.

The object of the present invention is to obtain a strong interior parts joining structure that is easily deformed by pushing up a floor mat or the like as described above, and the end of one interior part is connected with the lip of a welt. We propose to strengthen the overall rigidity of the welt by bending the tip of the interior parts on the interior side of the vehicle in the opposite direction of the vehicle body pad to which the welt is fixed to form a step. It is.

Embodiments of the present invention will be described below with reference to FIGS. 4 to 6, taking examples of a dash side finisher and a sparkling plate as interior parts, similar to the conventional example.

4 and 5 are exploded perspective views and sectional views corresponding to FIGS. 1 and 2 of the interior parts joining structure according to the present invention, and structural parts similar to those in FIGS. 1 and 2 are denoted by the same reference numerals. It is shown with .

The features of the present invention reside in that a lip 3b is formed on the inner surface of the well 3A to cover the two dash side finisher terminals, and in the shape of the tip portions 2a of the two dash side finisher terminals.

That is, as can be understood from FIGS. 5 and 6, there is a lip 3 in a portion of the welt 3A that is located on the inside of the vehicle interior from the lip 3b of the dash side finisher terminal that is worn by two people.
A stepped portion 2a is formed which is bent in the opposite direction of the sill B from the surface with which the sill B contacts, increasing the cross-sectional height h2. Therefore, the two dash side finisher terminals according to the present invention have a large cross-sectional dimension coefficient and a large cross-sectional quadratic coefficient.
Stable against screw loads and bending loads. Therefore, even if the two dash side finisher terminals are pushed up by the floor mat 5 or the like, the two dash side finisher terminals are not deformed, so that the waving of the floor mat 5 and the floating of the glittering plate 4 can be completely prevented.

In addition, in the above embodiment, the joint part between the dash side finisher terminal and the Kiraking plate was illustrated, but 1
The present invention is also applicable to joining a center pillar finisher, a rear wheel house garnish, and other parts.

As is clear from the above description, according to the present invention, it is possible to obtain a bonded structure with a good finish υ in which interior parts such as floor mats and other undulating grate do not float up.

Claims (1)

[Claims] 1) In a structure in which the ends of interior parts such as finishers are covered with the lip of a welt fixed to the vehicle body panel, and other interior parts such as a glittering plate are overlapped and joined to these, the lip of the welt at one end of the interior part is The part that is visible to the interior side is bent to the opposite side of the vehicle body panel from the contact surface with the lip to form a stepped portion, and the other interior component is superimposed on the stepped portion of the terminal of the interior component. Features: Automotive interior parts joint structure.
