JPH07323733A - Die-formed part structure of weather strip of automobile - Google Patents

Abstract

PURPOSE:To provide die-formed part structure of a weather strip of an automobile in which a part of a seal surface is not broken by a door glass even when the door glass elastically makes contact with a part of the seal surface of a hollow seal part on the car room side from a rising and lowering locus of the door glass. CONSTITUTION:This is die-formed part structure of a weather strip of an automobile constituted by installing a bottom cover 11 of high rigidity on a part corresponding to a base part and projectively providing a lip 15 to support an inwall of a seal surface of the hollow seal part 12 on the bottom cover 11 to improve a sealing property of the hollow seal part at the time when a door glass 90 elastically makes contact with it, a sectional shape of the aforementioned lip 15 is formed in a protruded circular arc shape toward the seal surface of the hollow seal part, and a roughly central part of the protruded surface is made contact with the inwall of the seal surface.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a weather strip for automobiles, especially for hard top vehicles.

[0002]

2. Description of the Related Art A description will be given with reference to FIGS. In the figure, one of the median lines from the apex angle of the isosceles triangle is filled, but the filled side represents the molding part, and the non-filled side represents the extrusion molding part. . Conventionally, as a molding portion structure such as a corner portion connected to an extrusion molding portion of a weather strip attached to an opening edge of a body of an automobile 40, a reaction force when the door glass 90 is elastically contacted with the hollow seal portion 12 is increased and the seal is formed. In order to improve the property, instead of inserting the pad into the hollow seal portion 12, a bottom lid 11 having high rigidity is attached to a portion corresponding to the base portion, and the bottom lid 11 reaches the inner wall of the sealing surface of the hollow seal portion 12. A lip 15 is provided so as to project. Reference numeral 16 is a core metal embedded in the inner surface of the hollow seal portion 12.

Further, roof side and center pillar side extruded parts 20, 30 connected to the die formed parts 10 at the corners.
Are configured as follows. That is, reference numeral 21 denotes a base portion which is attached to the roof portion with screws or the like, and a core metal (not shown) is embedded therein. Reference numeral 22 denotes a hollow seal portion integrally connected to a lower end on the indoor side of the base portion 21 so as to be rotatable around the lower end as an axis.
It is hooked on the inner surface of the outdoor part of. Reference numeral 23 denotes an interior lip projecting toward the indoor side from the lower end of the base portion 21 on the indoor side. Reference numeral 31 is a base portion that is attached to the center pillar through a retainer or the like, and 32 is a hollow seal portion that is integrally connected to the base portion 31, and a bridge 35 is installed between the seal surface and the base portion 31, The reaction force of is increased. Reference numeral 33 denotes an interior lip projecting toward the interior side at the interior side end of the hollow seal portion 32.

However, due to the balance between the reaction force of the weather strip hollow seal portion and the glass rigidity, the ascending locus YZ of the door glass 90 changes from the inner position C to the outer position D in FIG. At the time of reaching the position C, in the mold forming part of the conventional weather strip described above, the door glass 90 may sneak between the lip 15 and the surface on the indoor side in which the core metal 16 is embedded, and damage the part H. There is a problem that there is.

[0005]

The problem to be solved by the invention is that in the conventional weather strip mold forming structure, the door glass 90 has the lip 15 and the core metal 16 of the sealing surface of the hollow sealing portion 12 embedded therein. That is, it may get into the space between the indoor side surface and the H part and damage it.

[0006]

[Means for Solving the Problems] FIG. 1, FIG. 2, FIG. 4, and FIG.
Will be explained with reference to. According to the present invention, in order to enhance the sealing property of the hollow seal portion 12 when the door glass 90 is elastically contacted, the bottom lid 11 having a large rigidity is attached to a portion corresponding to the base portion, and the hollow seal portion 12 is attached to the bottom lid 11. Is a mold forming portion structure for a weather strip of an automobile, in which a lip 15 that supports the inner wall of the sealing surface is provided, and the cross-sectional shape of the lip 15 is formed in a convex arc shape toward the sealing surface of the hollow sealing portion. Then, the approximately convex portion of the convex surface is brought into contact with the inner wall of the sealing surface.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Explaining an embodiment, reference numeral 10 is a mold forming portion such as a corner portion of a weather strip to be attached to an opening edge of a body of an automobile, which is constructed as follows. That is, 11 is a bottom lid having a high rigidity attached to a portion corresponding to the base portion, 12 is a hollow seal portion that makes elastic contact with the door glass 90, and 15 is a lip protruding from the upper surface of the bottom lid 11. The cross-sectional shape is formed in an arc shape that is convex toward the back surface of the sealing surface of the hollow seal portion 12, and a substantially middle portion of the convex surface is brought into contact with the inner wall of the sealing surface. When it is elastically contacted with 12, the reaction force of the hollow seal portion 12 is increased to enhance the sealing property.
Reference numeral 16 is a core metal embedded in the inner surface of the hollow seal portion 12.

The roof side and center pillar side extruded parts 20, which are connected to the die formed parts 10 at the corners,
Each 30 is configured as follows. That is, 21
Is a base portion that is attached to the roof portion with screws or the like, and has a core metal (not shown) embedded therein. Reference numeral 22 denotes a hollow seal portion integrally connected to a lower end on the indoor side of the base portion 21 so as to be rotatable about the lower end as an axis.
It is hooked on the inner surface of the outdoor portion of No. 1. Reference numeral 23 denotes an interior lip projecting toward the indoor side from the lower end of the base portion 21 on the indoor side. Reference numeral 31 denotes a base portion which is attached to the center pillar via a retainer or the like, and 32 denotes a hollow seal portion which is integrally connected to the base portion 31, and a bridge 35 is provided between the seal surface and the base portion 31 to form a seal surface. The reaction force is increased. Reference numeral 33 denotes an interior lip projecting toward the indoor side at the indoor side end of the hollow seal portion 32.

The operation will be described. Door glass 90
4 is from the inner side position E to the outer side position F in FIG. 4, the convex portion of the lip 15 always supports the sealing surface when the door glass tries to move from the position E to the position F. And the door glass 90 is lip 1
5 and the surface on the indoor side in which the cored bar 16 is embedded do not sneak in, and the portion H of the sealing surface is not destroyed by the door glass 90.

[0010]

Since the present invention is constructed as described above,
From the ascending locus YZ of the door glass 90, when the door glass tries to move from the position E to the position F, the portion H of the sealing surface is not broken by the door glass 90.
