Problems solved by technology

Especially, in a door panel made by welding together plates of different thicknesses, since height differences are likely to exist between such welded plates, when a high-foaming sponge member that cannot apply sufficient sealing pressure is used, the above-mentioned pressure cannot be absorbed. Height difference, thus forming a gap, fear of degrading sealing performance

no. 1 approach

[0034] Next, a first embodiment of a weather strip that is attached around a door periphery of a vehicle (motor vehicle) will be described with reference to the drawings.

[0035] Such as figure 1 , figure 2 As shown, in the door opening 2 of the motor vehicle 1, a door 3 is provided in an openable and closable manner, and a sealing strip is installed around the periphery of the door 3 . In addition, the door 3 is made of panels such as an inner panel 5 and an outer panel 6 (see Figure 4 ). Therefore, the door panel of the present embodiment is constituted by panel members 5 , 6 .

[0036] Among these panels, the inner panel 5 is formed by welding panels of different thicknesses so that the hinge side ( figure 2 center left) and open side ( figure 2 middle right) with different thicknesses. This is because thick plate parts are used on the hinge side to ensure the rigidity of the hinge side. Therefore, the welding portion 5 a is exposed at the upper edge portion 3 a...

no. 2 approach

[0068] Next, a second embodiment of a weather strip which is installed around a door periphery of a vehicle (motor vehicle) will be described with reference to the drawings.

[0069] Such as Figure 7 , Figure 8 As shown, in the door opening 102 of the motor vehicle 101 , a door 103 is provided in an openable and closable manner, and a weather strip is installed around the periphery of the door 103 . In addition, the door 103 is made of panels such as an inner panel 105 and an outer panel 106 (see Figure 10 ). Therefore, the door panel of the present embodiment is constituted by panel members 105 , 106 .

[0070] Among these panels, the inner panel 105 is formed by welding panels of different thicknesses, and on the hinge side ( Figure 8 center left) and open side ( Figure 8 middle right) with different thicknesses. This is because a thick plate member is used on the hinge side to ensure rigidity on the hinge side. Therefore, the welding portion 105a is exposed at t...

Abstract

The invention discloses a door weather strip which is attached round a circumferential edge of a door of an automotive vehicle. An extruded portion 7 which makes up mainly an upper side portion of the door weather strip includes an attaching base portion 15 which is fixed to an inner panel 5 with clip members 13, a hollow main seal portion 16 which is brought into press contact with a circumferential edge of a door opening, a sub-seal lip 25 which is brought into press contact with the circumferential edge of the door opening in a position lying further transversely outwards than the main seal portion 16, a back-side lip 26 which is brought into press contact with a flange portion 27 formed on the circumferential edge of the door, a draining lip 30 which is formed to extend from an external side wall portion 19 of the attaching base portion 15 so as to be brought into press contact with the flange portion 27 and a water stopping rib 33 which is provided on a base bottom portion 17 of the attaching base portion 15 in such a manner as to be brought into press contact with an attaching surface 5b of the inner panel 5.

Description

technical field [0001] The present invention relates to a door weather strip installed around a vehicle door. Background technique [0002] Generally, a door weather strip is installed on a door periphery of a vehicle such as a motor vehicle. The door weather strip is made of, for example, EPDM rubber (ethylene propylene diene rubber), and includes a base portion fixed to the periphery of the door, and a hollow seal portion integrally formed with the base portion. In this way, when the door is closed, the door is fastened to the vehicle body through the abutment or pressure contact between the sealing part and the periphery of the door opening to form a seal between the door and the vehicle body, thereby preventing rainwater from entering the vehicle interior. [0003] In recent years, in order to achieve light weight and reduce manufacturing costs, various door sealing structures have been proposed, wherein the sealing strip clamping parts are omitted at the periphery of t...
