Problems solved by technology

[0004] However, if the amount of deflection D relative to the vertical sealing surface 25a of the hollow sealing portion 21 is set to be large, the reaction force becomes large when the door is closed, and the door 1 becomes difficult to close, resulting in a so-called door lock. Closing the question of exacerbation
In addition, if the amount of deflection D of the hollow sealing portion 21 is small to maintain good door closing performance, the elastic contact range and elastic contact force with respect to the vertical sealing surface 25a when the door 1 is sucked out are reduced, resulting in The problem of poor sealing

Embodiment Construction

[0032] First, the suction direction S will be described. When the car is running, the speed of the air flowing from front to rear along the side of the car increases, so the air pressure decreases, and the air pressure inside the car sandwiching the door glass and the air pressure outside the car become lower than the air pressure outside the car. On the other hand, the door is provided with hinges above and below the lower half of the metal cladding part, and no hinges are provided at the upper half of the door, that is, the periphery of the door glass in the closed state of the door glass. In addition, among automobiles, there are automobiles in which the upper half of the door (door glass portion) is inclined toward the inner side of the vehicle. In this type of automobile, if the door glass is completely closed and the door glass is completely closed, an external force inclined in a direction perpendicular to the door glass surface, that is, outward and upward, is generate...

Abstract

The invention provides a car door weather strip mounting structure capable of maintaining the high sealability even when a door is sucked outside a car when the car is traveling while maintaining the good door closability. The door weather strip 10 has a mounting base part 11 mounted on a retainer part 2a of a door sash 2, and a hollow seal part 12 which is integrated with the mounting base part 11 and elastically brought into contact with a body panel 5 when the door is closed. A part of the body panel 5 with the hollow seal part 12 elastically brought into contact therewith forms a flat parallel seal face 5a which is formed parallel or substantially parallel to the sucking direction S of a door 1 in a traveling mode.

Description

technical field [0001] The invention relates to a door sealing strip, which is installed on a door and window frame of an automobile, and wherein the hollow sealing part is in elastic contact with the cladding plate of the vehicle body. Background technique [0002] Description will be made with reference to FIGS. 6 to 8 . The door 1 of the vehicle is sucked out to the outside of the vehicle due to the pressure difference between the interior and the exterior of the vehicle generated during driving. Conventionally, in order to prevent the airtightness from being reduced due to the suction phenomenon, the door weather strip 20 attached to the door sash 2 is placed on the vertical sealing surface 25a of the body panel 25 formed almost perpendicularly to the closing direction C of the door 1 . The deflection amount D of the hollow sealing portion 21 is set sufficiently large. Thereby, even if the door 1 is sucked out to the outside of the vehicle, the airtightness can be main...
