Description

  The present invention relates to a weather strip mounting structure that is mounted on an automobile door.

  Conventionally, as shown in FIG. 11, the weather strip 9 attached to the peripheral edge D of the automobile has an attachment base 11 that elastically contacts and seals the opening lip B of the vehicle body when the door is closed, and the width direction of the attachment surface 12. The entire surface is extruded and bent in advance so as to coincide with the inclined surface S, the bent portion K, and the flat surface portion H of the door peripheral portion D.

However, when the weather strip 9 is adhered to the door peripheral portion D after the double-sided tape 6 is applied in advance only to the flat surface portion 13 corresponding to the flat surface portion H of the mounting surface 12 of the mounting base portion 11, Since the double-sided tape 6 is not affixed to the portion S, there is a problem that the attachment base 11 is not sufficiently fixed and is easily lifted by an impact when the door is closed.
In addition, when the double-sided tape 6 is applied to the entire width direction of the mounting surface 12 of the mounting base 11 as shown in FIG. 12, air is released from the gap between the bent portion 12a of the mounting surface 12 and the double-sided tape 6 during the bonding. There was a problem that sufficient adhesive strength could not be obtained.
Furthermore, as shown in FIG. 13, when the double-sided tape 6 is separately attached to the slope portion 14 and the plane portion 13 corresponding to the slope portion S and the plane portion H of the mounting surface 12, respectively, a large number of man-hours for attachment are required. And the cost was high.
SUMMARY OF THE INVENTION In view of the above-described conventional problems, an object of the present invention is to provide a weather strip attachment structure in which a weather strip is firmly attached to a door peripheral portion and is easy to attach.

Means to solve the problem

In order to achieve such an object, according to the present invention, the first invention is attached to the door peripheral edge D as shown in FIGS. 1 and 2, and is attached to the vehicle body opening edge B or the peripheral edge D of another door when the door is closed. In a weather strip mounting structure that elastically contacts and seals the seal lip 2, the mounting base 1 of the weather strip 3 is extruded with the mounting surface 4 flat in the entire width direction, and the back surface of the mounting base 1. The mounting base 1 is bonded along the door peripheral edge D with the double-sided tape 6 attached to the entire width direction of the mounting surface 4.
As shown in FIGS. 7 and 9, the second invention of the present invention is a weather strip which is attached to the door peripheral edge D and elastically contacts and seals the opening lip B of the vehicle body or the peripheral edge D of the other door when the door is closed. In the mounting structure of 3b, the mounting base portion 1b of the weather strip 3b is extruded in a bent shape so that the entire width direction of the mounting surface 4b matches the bent portion K or the curved portion R of the door peripheral portion D. At the same time, a notch 5b is provided on the back surface of the mounting base 1b. After the mounting base 1b is deformed into a flat state with the notch 5b as a fulcrum, a double-sided tape 6 is applied to the entire width of the mounting surface 4b. The mounting base 1b is bonded along the door peripheral edge D.
As shown in FIGS. 3 to 6, the third invention of the present invention is a weather strip which is attached to the door peripheral edge D and elastically contacts and seals the seal lip 2a to the opening edge B of the vehicle body or the peripheral edge D of another door when the door is closed. In the mounting structure 3a, the mounting base portion 1a of the weather strip 3a forms a mounting surface portion 7 provided with one or a plurality of notches 5a on the back surface and a covering portion 8 for covering the notches 5a of the mounting surface portion 7. It is made up of.
As shown in FIG. 10, the fourth aspect of the present invention is the attachment of a weather strip 3c which is attached to the door peripheral edge D and elastically contacts and seals the seal lip 2c to the vehicle body opening edge B or other door peripheral edge D when the door is closed. In the structure, the mounting base portion 1c of the weather strip 3c is extrusion-molded by forming a thin-walled thin mounting surface portion 91 that is flat on the entire surface and a support portion 92 that covers and supports the thin mounting surface portion 91 on the back side, and the width direction of the mounting surface 4c. The double-sided tape 6 is adhered to the entire surface along the door peripheral edge D.

The invention's effect

  The weather strip mounting structure of the present invention has the mounting bases 1, 1a, 1b and 1c attached in advance with the mounting surfaces 4, 4a, 4b and 4c being flat in the entire width direction, and then the double-sided tape 6 is applied. Since the conventional weatherstrip is bonded along the part D, the mounting surface of the mounting base is extruded in advance in accordance with the bent part K of the door peripheral part D, and the double-sided tape 6 is attached. As in the case where the adhesive force is weak and floats when the door is closed, air enters when the door is bonded and the adhesive force cannot be secured, or when the double-sided tape 6 is separately attached to the slope portion S and the flat portion H, respectively. It has a feature that it can solve problems such as high man-hours and high costs.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In the first invention of the present invention, as shown in FIG. 1, a weather strip 3 having a mounting base 1 provided with a seal lip 2 is extruded by making the mounting base 1 flat in the entire width direction of the mounting surface 4. ing.
Moreover, the notch 5 is provided in the back surface of the attachment base 1 in the position corresponding to the bending part K of the boundary of the slope part S and the plane part H of the door peripheral part D, as shown in FIG.
For assembling the weather strip 3 to the door peripheral portion D, first, a double-faced tape 6 is applied to the entire width direction of the mounting surface 4 of the mounting base 1, and then the mounting base 1 is bent at the notch 5, Bonded along the portion S, the bent portion K, and the plane portion H. When the door is closed, the seal lip 2 is elastically contacted with the opening edge B of the vehicle body for sealing. Note that the seal lip 2 is not shown in the opening B of the vehicle body but is not shown in the figure, and may be elastically brought into contact with other front or rear doors for sealing.
Therefore, the weather strip 3 can be assembled easily and reliably by the notch 5.

In the second invention of the present invention, as shown in FIG. 7, the mounting base portion 1b of the weather strip 3b provided with the seal lip 2b has the mounting surface 4b as the slope portion S, the bent portion K and the flat portion of the door peripheral portion D. Extrusion-molded in a bent shape along H.

A double-sided tape 6 is affixed, and then bonded along the inclined surface S, the bent portion K, and the flat surface portion H of the door peripheral portion D as shown in FIG.

In the third aspect of the present invention, as shown in FIG. 3, a weather strip 3a having a mounting base 1a provided with a seal lip 2a forms a mounting surface 7 on the mounting base 1a, and a notch 5a is formed on the back of the mounting surface 7. And a covering portion 8 for covering the notch 5a is formed.
As shown in FIG. 4, the weather strip 3 is assembled to the door peripheral portion D. First, the double-faced tape 6 is applied to the entire width direction of the mounting surface 4a of the mounting surface 7 of the mounting base 1a, and then the mounting base 1 is notched 5a. And is bonded along the inclined surface S, the bent portion K, and the flat surface portion H of the door peripheral portion D.
5 and 6 show a modification of the weather strip 3a shown in FIG. 3, and shows a case where a plurality of notches 5a are provided on the back surface of the mounting surface portion 7. FIG. In addition, this invention is applied also when the door peripheral part D shown in FIG. 6 does not form the bending part K but forms the curved part R. FIG.
