Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a hollow type drip weather strip which is attached to a front pillar portion of an automobile and elastically contacts an upper end portion of a door.

[0002]

[Prior art]

 Description will be made with reference to FIGS. 1 to 7. Conventionally, as the hollow type drip weather trip 40, the one having the configuration shown in FIGS. 1 and 2 is used. That is, a substantially U-shaped base portion 41 that is fitted to a flange 11 that protrudes in a substantially horizontal direction on the outer surface of the front pillar portion 10 of an automobile, and is connected to the upper surface of the base portion 41 via a connecting portion 45. A hollow seal portion 42, a lip 43 projecting from the outer surface of the substantially U-shaped base portion 41, and two small upper and lower lips 46 and 47 projecting from the indoor surface of the hollow seal portion 42. The hooking portion 44 is formed by the hooking portion 44 and the hooking portion 44 sandwiches the substantially U-shaped convex portion 21 formed on the molding 20 provided along the outer surface of the front pillar portion 10. In addition, the hollow seal portion 42 and the lip 43 are elastically contacted with the inner surface of the upper end portion of the door 30 with the door 30 closed.

However, the conventional hollow type drip weather strip 40 has a problem that the following defects are caused by a slight variation in the positional relationship of the molding 20 with respect to the flange 11. That is, when the molding 20 is displaced upwards (plus side) with respect to the flange 11, as shown in FIGS. 3 and 4, when the door 30 is closed, the hollow seal portion 42 pressed by the door 30 and the molding 20 are separated from each other. Interfere with each other, the hollow seal portion 42 is deformed and rises, jumps out from between the door 30 and the molding 20, and the appearance is impaired. On the other hand, when the molding 20 is displaced downward (minus side) with respect to the flange 11, a gap S is created between the hollow seal portion 42 and the molding 20, as shown in FIG. Be done.

[0004]

[Problems to be solved by the device]

 The problem to be solved is that the conventional hollow type drip weather strip 40 has a small variation absorption force for absorbing a slight variation in the positional relationship of the molding 20 with respect to the flange 11, or a flexibility for the variation. Also, as shown in FIG. 5, when the door 30 is opened and closed, the small lip 46 of the hollow seal portion 42 does not move largely, that is, when the door 30 is closed, the small lip 46 is separated from the upper surface of the molding 20. To provide a weatherstrip that never opens.

[0005]

[Means for Solving the Problems]

 The first device will be described with reference to FIGS. 8 to 10. A first invention is that a hollow seal portion 42 is connected to an upper surface of a substantially U-shaped base portion 41 that is fitted to a flange 11 that is protruded in a substantially horizontal direction on an outer surface of a front pillar portion 10 of an automobile through a connecting portion 45. The upper and lower small lips 46, 47 are provided on the inner surface of the hollow seal portion 42 so as to project to form the hooking portion 44, and the hooking portion 44 allows the front pillar portion 10 to move. With the substantially U-shaped convex portion 21 formed on the upper portion of the molding 20 provided along the outer surface, the locking portion 44 is hooked on the substantially U-shaped convex portion 21, and the door 30 is closed. A drip weather strip 40 of a hollow type in which the hollow seal portion 42 is elastically contacted with the inner surface of the upper end portion of the door 30, and the drip weather strip 40 projects from the inner surface of the hollow seal portion 42. The lower lip of the upper lip 46 In which by comprising projecting a downward small auxiliary lip 48.

A second device will be described with reference to FIG. The second invention is a type without the connecting portion 45 in the first invention.

A third device will be described with reference to FIG. The third invention is a type without the substantially U-shaped convex portion 21 and the lower small lip 47 in the first invention.

【Example】

 An embodiment of the first invention will be described with reference to FIGS. 8 to 10. 10 is a front pillar portion of an automobile, 11 is a flange projecting from the outer surface of the front pillar portion 10 in a substantially horizontal direction, 20 is The molding is provided along the outer surface of the front pillar portion 10, and a substantially U-shaped convex portion 21 is formed on the upper portion. 30 is a door.

Reference numeral 40 is a hollow type drip weather strip of the present invention, 41 is a substantially U-shaped base portion fitted to the above-mentioned flange 11, 42 is an upper surface of the base portion 41 via a connecting portion 45. The joined hollow seal portion 43 is a lip protruding from the outer surface of the substantially U-shaped base portion 41, and together with the hollow seal portion 42, the upper end portion of the door 30 in the closed state of the door 30. It is designed to make elastic contact with the indoor surface of the.

Reference numeral 44 denotes a hooking portion that is formed on the inner surface of the hollow seal portion 42 and that hooks on the convex portion 21, and includes two upper and lower small lips 46, 47 that sandwich the convex portion 21. And a small auxiliary lip 48 that is directed obliquely downward at a lower root of the upper small lip 46 while keeping an angle α.

To explain the operation, the hollow type drip weather strip 40 of the present invention operates as follows due to the variation in the positional relationship between the molding 20 and the flange 11.

That is, whether the molding 20 is displaced upward (plus side) or downward (minus side) with respect to the flange 11, when the hollow seal portion 42 is pressed by the closed door 30, The small auxiliary lip 48 is pushed down by 20 and pulled by the small auxiliary lip 48, and the upper small lip 46 is pulled down, and the small auxiliary lip 48 adheres to the upper surface of the substantially U-shaped convex portion 21. The problem of rising, popping out, or generation of a gap of the hollow seal portion 42 is completely solved.

Therefore, unlike the conventional one, the hollow seal portion 42 is not deformed, rises, and pops out from between the door 30 and the molding 20. That is, the movement of the small lip 46 of the hollow seal portion 42 when the door 30 is opened and closed becomes small. When the door 30 is closed, the hollow seal portion 42 does not rise and pop out, and the small lip 46 does not separate from the upper surface of the molding 20 and open.

An embodiment of the second invention will be described with reference to FIG. The second invention is a type without the connecting portion 45 in the first invention, and is selected according to the shape between the door and the body panel.

A third device will be described with reference to FIG. The third invention is a type without the substantially U-shaped convex portion 21 and the lower small lip 47 in the first invention, which is elastically contacted with the molding or the body panel 13.

[0016]

[Effect of device]

 Since the present invention is configured as described above, the absorbing power of the positional variation with respect to the flange 11 of the molding 20 or the flexibility for the variation is increased, and the hollow seal portion 42 rises when the door 30 is closed. It is possible to prevent popping out and opening of the small lip 46.
