Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a waist seal structure for automobile doors.

[0002]

2. Description of the Related Art As shown in FIG. 8, a door glass 4 rises and falls from an upper opening 3 of a door body 2 of a front side door 1 of an automobile. The door glass 4 is as shown in FIG. The upper opening 3 (only outside the cabin is shown)
It is adapted to be sealed by the waist seal 5 of the waist molding 8 provided on the side edge of the.

In FIG. 6, a waist molding 8 is attached to a door outer panel 6 via a clip 7. Two rubber sealing lips 9 and 10 are made from the upper side on the inside of the waist molding 8 in the vehicle interior and a rubber is formed below the sealing lips 9. Holding member 11
The waist seal 5 having the above is additionally formed.

The seal lips 9 and 10 are in close contact with the outer surface of the ascending / descending door glass 4 to seal and hold the holding member 11 so as to suppress the displacement of the door glass 4 to the outside of the vehicle compartment. The seal lips 9 and 10 and the holding member 11 are provided with bristles 12 at the contact portion of the door glass 4 (this structure is shown in Japanese Utility Model Laid-Open No. 61-54921).

[0005]

However, in the above-mentioned conventional waist seal structure, when the door glass 4 is in a fully opened state or the like and the runout occurs in the vehicle width direction,
When the glass 4 is raised, there is a problem that the upper end of the door glass 4 may come into contact with the lower surface of the holding member 11 and the door glass 4 may not be smoothly raised.

FIG. 7 shows a load-deflection characteristic when the door glass 4 collides with the waist seal 5 in the vehicle width direction. The characteristic graph is abrupt when the door glass 4 collides with the holding member 11. Since it rises up, there is a problem that when the door is closed, the impact that the door glass 4 collides with the holding member 11 is large, and a tapping sound is generated in some cases.

Therefore, the present invention provides a waist seal structure for an automobile door, which can suppress the generation of hammering sound when the door is closed, while ensuring the smooth elevation of the door glass.

[0008]

In a waist seal structure for an automobile door, which is attached to a side edge of an upper opening portion of a door body through a core material and is in close contact with a glass surface of an ascending / descending door glass, a door glass is provided at an upper portion. A sealing lip that is in close contact with, and below this sealing lip, a bow-shaped hollow holding lip that rises diagonally upward is provided, and the bottom of the holding lip facing this hollow part is located above the holding lip. An easily bendable part that allows rotation is provided, and an inclined surface that is inclined upward toward the door glass side is formed at the tip of the holding lip. Corresponding to this inclination angle, the holding lip is provided below the base of the seal lip. A regulation surface is provided to receive the inclined surface.

[0009]

Since the door glass is fully opened and the door glass is displaced in the vehicle width direction, for example, even if the door glass 4 is raised in this state, the holding lip is formed so as to rise obliquely upward. , The retaining lip does not prevent the door glass from rising.

Further, when the door glass is strongly closed in the half-opened state, for example, the holding lip bends at the easily bendable portion to rotate to receive the door glass softly, and then the tip of the holding lip is inclined. The surface abuts against the restriction surface below the root of the sealing lip, at which point the lower part of the retaining lip is bowed and taut, so that displacement of the door glass is prevented there.

[0011]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT An embodiment of the present invention will be described below with reference to FIG.

As shown in FIG. 1, the door outer panel 6 and the door inner panel 13 constitute a door body 2,
The point that the door glass 4 is moved up and down through the upper openings 3 of the door outer panel 6 and the door inner panel 13 is the same as the above-mentioned conventional one.

A waist molding 15 is attached to the upper end of the door outer panel 6 via a clip 14, and a waist seal 16 is additionally formed on the waist molding 15. Further, a trim material 17 is attached to the upper portion of the door inner panel 13, and the trim material 17
A waist seal 18 is attached to the upper outer surface of the. Since the waist seal 16 of the waist molding 15 attached to the door outer panel 6 and the waist seal 18 of the door inner panel 13 have the same structure, the waist seal 18 of the door inner panel 13 will be described.

As shown in FIG. 1, the waist seal 18 is provided with a seal lip 20 on an upper portion of a core material 19, and below the seal lip 20, there is provided a hollow holding lip 21 having an arcuate shape which rises obliquely upward on the core material 19. Be prepared. Core material 1
As shown in FIG. 2, reference numeral 9 has a claw 19b that is raised on a mounting surface 19a corresponding to the upper outer surface of the trim member 17,
The raising claw 19b is inserted into the insertion hole on the trim material 17 side, and the bent waist seal 18 is fixed to the trim material 17.

The seal lip 20 of the waist seal 18 is in close contact with the inner surface of the door glass 4, and a flock 22 is provided in the close contact portion of the seal lip 20 with the door glass 4.

A retaining lip 21 below the seal lip 20.
Is a thick-walled portion 21a, which is provided from the lower side portion to the tip portion and has a thickness similar to that of the seal lip 20 as a lower side portion,
The hollow portion 21c is formed by the upper thin portion 21b, and the holding lip 21 is allowed to rotate upward (indicated by an arrow in FIG. 1) at the base of the thick portion 21a facing the hollow portion 21c. A cutout portion 23 is formed as an easily bendable portion. The flock 22 is provided on the outer surface of the thick portion 21a.

The door glass 4 is provided at the tip portion of the holding lip 21, specifically, at the connecting portion between the thick portion 21a and the thin portion 21b.
An inclined surface 24 inclined upward toward the side is formed, and a regulation surface 25 for receiving the inclined surface 24 when the holding lip 21 rotates in the arrow direction of FIG. 1 is formed corresponding to the inclined surface 24. It is provided on the core material 19 below the root of the seal lip 20. The restriction surface 25 is provided with the flocked hair 22.

According to the structure of the above embodiment, when the door glass 4 rises at the proper position in the vehicle width direction, both the holding lip 21 and the seal lip 20 rotate upward as shown in FIG. Since the door glass 4 comes into close contact with the door glass 24 smoothly, even if the door glass 24 hits the holding lip 21 early due to an assembly error or the like, the door glass 4 can smoothly rise.

When the door glass 4 is, for example, half-opened and the door is closed, the door glass 4 is displaced toward the vehicle interior as shown in FIG. It is rotated to and pressed against the trim member 17 side. Here, the holding lip 21 has a thick portion 21a.
Since the notch 23 provided in the door smoothly rotates, the door glass 4 can be softly received.
As shown in FIG. 5, the thick portion 21a faces the door glass 4.

At this time, since the inclined surface 24 of the holding lip 21 abuts on the regulating surface 25 of the core material 19, the tip of the holding lip 21 does not move upward thereafter. Therefore, the thick portion 21a becomes bow-shaped and receives the attached door glass 4 (position a in FIG. 5).

Next, the door glass 4 is further pressed.
On the other hand, the thick portion 21a of the holding lip 21 absorbs impact energy by being compressed and deformed, and finally exhibits a stopper function of preventing the displacement of the door glass 4 in a crushed state as shown in FIG. 4 ( Position b in FIG. 5).

In this way, the holding lip 21 is provided with a stopper function while preventing the reaction force from rising rapidly (relaxation zone in FIG. 5).

In this embodiment, the waist molding 15 and the waist seal 16 are also provided on the door outer panel 6 side.
Since the waist seal 16 is also provided with the seal lip 26 and the holding lip 27 having the same configuration as that of the waist seal 18, even if the door panel 4 is displaced to the outside of the vehicle, Demonstrate the same function as.

[0024]

As described above, according to the present invention, the holding lip can be easily rotated by the easily bendable portion even when the door glass is lifted from the displaced position, and the holding lip can be opposed thereto. It does not prevent the rise.

Further, when the door is closed in the half-opened state, the holding lip is bent by the easily bendable portion to rotate and receive the door glass smoothly at the initial stage of contact of the door glass. Can be prevented.
After the inclined surface of the holding lip comes into contact with the regulation surface on the core material side, the displacement of the door glass is received by the compressive deformation of the lower portion of the holding lip, so that the stopper function is exerted and the displacement of the door glass is surely performed. Can be stopped.
