Abstract

PURPOSE:To prevent the infiltration of water into the vehicle interior during high pressure car wash by extending a roof weatherstrip with a fin part into a position above an opening seal formed of an opening trim and a hollow seal part, and pressing both strips by the plate body of a door. CONSTITUTION:A hollow seal part 52 is integrally connected to the outer surface of an opening trim 51, fittingly fixed to the flange part 12 of a body opening edge 10 on the lower side of a waist line, so as to form an opening seal 50. The lower end part of a roof weatherstrip 30 fitted to the upper side of the waist line is extended into a longitudinal vehicle exterior side position above the opening seal 50 so as to form a fin part 35 covering the opening seal 50. In addition, a door is provided with a plate body 60 that can press the lower and upper ends of both seals 30, 50. Accordingly, there is hardly any influence of dispersion of fitting accuracy, and the infiltration of water W into the vehicle interior is impeded during high pressure car wash so as to prevent water leak.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a weather strip sealing structure for sealing between a vehicle body and a door.

[0002]

2. Description of the Related Art Conventionally, as shown in FIGS. 1 to 6, a waist line L- of a door 20 at an opening edge 10 of an automobile body is used.
Roof weather strip 3 to be installed above L
As a structure for sealing between the lower end of 0 and the door 20,
The waist line L- of the door 20 is attached to the lower end portion of the roof weather strip 30 and the fin portion 35 connected to the lower side thereof.
Door weather strip 40 attached below L
There is used a seal which is formed by superimposing the upper end portion and the fin portion 45 connected to the side of the upper end portion on each other. In addition, the above-mentioned seal structure has one door 20.
As for, the front part A and the rear part B are provided. Reference numeral 11 is a retainer into which the base portion 31 of the roof weather strip 30 is fitted, and 25 is a mirror bracket attached to the front portion of the door 20.

However, in the above-described conventional automobile seal structure, the lower end portion of the roof weather strip 30 and the upper end portion of the fin 35 and the door weather strip 40 and There is a problem that the seal between the fin portion 45 is broken, and as shown in FIGS. 3 to 6, during high-pressure car washing, the water W enters the inside of the vehicle through the gap.

[0004]

The problem to be solved by the present invention is that in the above-described conventional automobile seal structure, the seal is broken at the time of high-pressure car wash due to variations in the construction of the body opening edge portion 10 and the door 20, and the like. Water is the entry into the car.

[0005]

Means for Solving the Problems FIGS. 1 and 7 to 11
Will be explained with reference to. The present invention is waistline L-L
The hollow seal portion 5 is provided on the outer surface of the opening trim 51 fitted to the flange portion 12 of the body opening edge 10 that is substantially lower than the above.
2 are connected together to form the opening seal 50,
A fin portion 35 that extends a lower end portion of a roof weather strip 30 mounted substantially above the waist line L-L to a position above the opening seal 50 on the vehicle outer side in the front-rear direction and covers the opening seal 50 at the lower end portion. The door 20 is provided with a plate-like body 60 capable of pressing the lower end portion of the roof weather strip and the upper end portion of the opening trim.

[0006]

EXAMPLES Examples will be described. 10 is a vehicle body opening edge, 20 is a door, LL is a waist line of the door 20, 25 is a mirror bracket, and 30 is a waist line of the door 20 having a body opening edge 10. The roof weather strip is attached to a portion above LL and includes a base portion 31 attached to the body opening edge 10 via a retainer 11, and a hollow seal portion 32 integrally connected to the base portion 31. Reference numeral 35 denotes a fin portion integrally connected to the side of the lower end of the roof weather strip 30, and 50 denotes an opening seal attached to the body opening edge 10 below the waist line L-L. It comprises an opening trim 51 to be worn and a hollow seal portion 52 integrally connected to the outer surface of the opening trim 51. In addition, the vertical end of the fin portion 35 is formed in a substantially arcuate cross section, and is overlapped with the outer surface of the hollow seal portion 52 of the opening seal 50. 60
Is a plate-like member attached to the height of the waist line L-L on the periphery of the door 20, and is superposed on the roof weather strip 30 and the fin portion 35 thereof. Therefore, the door weather strip 4 in the figure
0 is not prepared.

The operation will be described. Since the roof weather strip 30, the fins 35 thereof, and the opening seal 50 are all attached to the body opening edge 10, the roof weather strip is not easily affected by the variation in the construction, and the roof weather during high-pressure car washing. Even if the seal between the lower end of the strip 30 and the door 20 is broken and water tries to enter the inside of the vehicle, the fins 35 and the plate-shaped body 60 are further overlapped with the opening seal 50 closer to the inside of the vehicle to prevent water from entering Water leakage does not occur due to the seal structure.

[0008]

Since the present invention is constructed as described above,
It is not easily affected by variations in construction, and prevents water from leaking into the interior of the car during high-pressure car washing and completely prevents water leakage.
