Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a sealing structure for the upper end of a center pillar, and more particularly, to a sealing structure for the upper end of a center pillar in which the center pillar is erected from a floor panel to approximately the vicinity of the upper end of a door panel. .

In general, in the case of a four-door hardtop vehicle 1, when the front door 2 and rear door 3 are closed, the center pillar is not visible between the front and rear doors 2 and 3, as shown in Figure 1. However, when both the front and rear doors 2 and 3 are removed, a center pillar 5 is provided that stands up from the floor panel 4 to approximately the vicinity of the upper ends of the door panels 2a and 3a, as shown in FIG. The rear door 3 is attached to the center pillar 5 via a hinge (not shown). By the way, the seal structure at the upper end of the center pillar 5 between the front door 2 and the rear door 3 was constructed as shown in FIGS. 3 and 4. That is, 6 is the center pillar 5
A center pillar spacer attached to the upper end of the first seal lip 6a that contacts the inside of the rear end of the front door 2 (the rear end of the front weather strip 7 in the figure) from the center pillar spacer 6. The center pillar spacer 6, including the first seal lip 6a, functions as a shock absorber that absorbs the impact when the front door 2 is closed. on the other hand,
A tongue-shaped center seal rubber 8 is attached to the front end of the rear door glass 3b, and the tip of the center seal rubber 8 is folded back toward the exterior of the vehicle in the X direction and brought into contact with the inside of the rear end of the front door glass 2b. This seals between the rear door glass 3b and the windshield 2b, and also brings the tip of the center seal rubber 8 into contact with the first seal lip 6a to seal the rear end of the front door glass 2b and the first seal lip 6a. A seal is also provided in between. Furthermore, as shown in FIG. 5, rear door weather strips 9 are attached to the outer periphery of both side edges and the lower edge of the rear door panel 3a.
By bringing the second seal lip 9a protruding from the rear door weather strip 9 into contact with the center seal rubber 8, and by bringing the front end into contact with the center pillar spacer 6,
A seal is provided between the rear door 3, the center seal rubber 8, and the center pillar spacer 6. In FIG. 3, 10 is a center pillar garnish, 11 is a door trim, and in FIG. 5, 12 and 13 are weather strips and moldings attached to the upper edge of the rear door panel 3a.

However, in the seal structure of the upper end of the center pillar described above, the first seal lip 6a protruding from the center pillar spacer 6 extends substantially straight, and the protruding base 6a' of the first seal lip 6a More center seal rubber 8
Since the tip of the first seal lip 6a is located forward, the tip of the first seal lip 6a is inclined forward. On the other hand, the trajectory P (Fig. 4) drawn by the tip of the center seal rubber 6 when the rear door 3 is opened is as follows.
Since the center seal rubber 8 has an arc shape toward the rear in the Y direction of the vehicle interior, the tip of the center seal rubber 8 presses and slides on the first seal lip 6a, which is tilted forward, so that this sliding part is worn out. This results in deterioration of sealing performance.

Furthermore, since the first seal lip 6a extends straight and the tip of the center seal rubber 8 is folded back, the first seal lip 6a, the tip of the center seal rubber 8 and A space A is formed between the seal lip 9a and the inside of the front door glass 2b, while the second seal lip 9a is formed in a straight shape, and its tip abuts against the center pillar spacer 6 in a polymeric manner, so that the tip of the second seal lip 9a is formed in a straight shape. Since it is inclined in the direction Y of the room, a large space B is created between the second seal lip 9a, the center pillar spacer 6, and the center seal rubber 8.
is formed. When the spaces A and B are formed in this manner, wind leakage, water leakage, etc. occur through these portions. Further, due to the spaces A and B, noise from outside the vehicle interior X easily enters the vehicle interior Y, resulting in a problem in that the quietness of the vehicle interior Y is impaired.

In view of such conventional problems, the present invention has been developed by forming the first seal lip so as to be located outside the trajectory of the tip of the center seal rubber that moves toward the interior of the vehicle when the rear door is opened. In addition to preventing wear of the seal lip and the center seal rubber, the tip of the first seal lip is formed closely following the shape of the tip of the center seal rubber, and the second seal lip is formed close to the tip of the center seal rubber. The first seal lip is formed by extending closely along the inside of the passenger compartment to the first seal lip, and by bending the tip end toward the inside of the passenger compartment from a position where it abuts the first seal lip. , the space that should be formed between the center seal rubber and the front door glass, and the space that should be formed between the first seal lip, the second seal lip, and the center seal rubber, respectively, to eliminate wind leaks, water leaks, etc. In addition to preventing noise from entering the vehicle, it also blocks noise from outside the vehicle and improves the quietness inside the vehicle.

Hereinafter, one embodiment of the present invention will be described in detail based on the drawings.

Incidentally, when describing one embodiment of the present invention, the same parts as those in the conventional structure will be described with the same reference numerals.

That is, FIG. 6 is a sectional view showing the seal structure of the present invention, where 6 is a center pillar spacer attached to the upper end of a center pillar (not shown), and 6a is a first seal lip protruding from the center pillar spacer 6. , 8 is a center seal rubber, and 9a is a second seal lip protruding from the rear door weather strip 9. Said first seal lip 6
The center part of the first seal lip 6a is formed in a substantially dogleg shape so as not to interfere with the trajectory P of the tip of the center seal rubber 8 that moves toward the interior of the vehicle when the rear door is opened. . The tip of the second seal lip 9a is formed into an L-shape in a free state, as shown by a chain line. Furthermore, when the door is opened and closed, the tip of the second seal lip 9a draws a trajectory P' in a free state, and when the door is closed, the second seal lip 9a is inserted between the first seal lip 6a and the center seal rubber 8. At this time, the L-shaped portion of the second seal lip 9a is bent as shown by the solid line in the figure. Further, the tip of the first seal lip 6a is formed closely along the shape of the tip of the center seal rubber 8 on the outside X side of the vehicle, so that when the door is closed, the first seal lip 6a, the center seal rubber 8, the front No space is formed between the door glass 2b and the door glass 2b. Furthermore, the second seal lip 9a extends closely along the interior side of the center seal rubber 8 to the first seal lip 6a, and the tip of the second seal lip 9a is connected to the first seal lip 6a. The first seal lip 6 is bent inward from the position where it abuts the seal lip 6a to form a substantially L-shape.
a, no space is formed between the second seal lip 9a and the center seal rubber 8.

With the above configuration, the first seal lip 6a is formed to be located outside the trajectory P of the tip of the center seal rubber 8, so that the tip of the center seal rubber 8 presses against the first seal lip 6a when the rear door is opened. Since there is no sliding,
Abrasion of the center seal rubber 8 and the first seal lip 6a can be prevented. Therefore, the sealing performance between the center seal rubber 8 and the first seal lip 6a does not deteriorate. In addition, by changing the shapes of the first seal lip 6a and the second seal lip 9a, when the front and rear doors are closed, the space between the first seal lip 6a, the center seal rubber 8, the front door glass 2b, and the Since no space is formed between the first seal lip 6a, the second seal lip 9a, and the center seal rubber 8, the intrusion of wind leakage, water leakage, and noise outside the vehicle interior is prevented.

FIG. 7 shows another embodiment in which the first seal lip 6a is formed into a hollow shape. That is, by forming the first seal lip 6a in a hollow shape in this manner, the rigidity of the first seal lip 6a can be improved, and the seal lip can be made into a so-called strong seal lip. Furthermore, even in this example,
The rear wall 6b of the first seal lip 6a is formed to be located outside the trajectory P of the tip of the center seal rubber 8, and there is a space between the first seal lip 6a, the center seal rubber 8, and the front door glass 2b. formed so that it is not provided,
It goes without saying that the second seal lip 9a is formed into a substantially L-shape so that no space is provided between the first seal lip 6a, the second seal lip 9a, and the center seal rubber 8.

As explained above, in the seal structure of the upper end of the center pillar which is installed upright from the floor panel to the vicinity of the upper end of the door panel according to the present invention, the first seal lip protruding from the center pillar spacer is attached to the tip of the center seal rubber. Since the center seal rubber tip is formed to be located outside the trajectory of the center seal rubber, the tip of the center seal rubber and the first seal lip do not come into sliding contact when the rear door is opened. Therefore, it is possible to prevent the tip of the center seal rubber and the first seal lip from being worn out, thereby preventing a reduction in the sealing effect. Further, the tip of the first seal lip is formed closely along the shape of the tip of the center seal rubber, and the second seal lip is formed closely along the cabin side of the center seal rubber. By extending the seal to the first seal lip and bending the tip inward from the position where it abuts the first seal lip, the first seal lip, center seal rubber, and front door glass The space that should be formed between the first seal lip, the second seal lip, and the center seal rubber can be eliminated. Therefore, it is possible to prevent wind leakage, water leakage, etc. that occur when each of the above-mentioned spaces is formed, and also to block noise from outside the vehicle interior and improve the quietness inside the vehicle interior. be effective.
