Description

[Detailed Description of the Invention] Industrial Application Field This invention relates to an improvement of a weather strip for a center pillar of a pillared hardtop vehicle.

BACKGROUND ART This type of center pillar structure has conventionally been shown in FIGS. 4 and 5 (for example, see Japanese Utility Model Application Publication No. 60-45272).

The vehicle shown in FIG. 4 is a four-door hardtop vehicle called a pillared hardtop vehicle, and between the front door 10 and rear door 20 there is a center pillar 3 extending from the floor to the roof.
0 is set.

A retainer 40 is joined to the center pillar 30 as shown in FIG. 5, and a weather strip 50 is further attached to the retainer 40. 60 is a welt that covers the joint of the center pillar 30.

The retainer 40 includes a base plate portion 41 having a straight horizontal cross section joined to the center pillar 30, and a holding portion 42 protruding from the front and rear ends of the base plate portion 41 to the outside of the vehicle.
The tips of the holding parts 42 are bent inward so as to face each other.

The weather strip 50 is a hollow rubber material whose horizontal cross section is approximately semicircular, and the weather strip 50 is a hollow rubber material whose horizontal cross section is approximately semicircular.
0, and a sealing portion 5 that comes into elastic contact with the door glasses 11, 21 and bends inward when the doors 10, 20 are closed and the door glasses 11, 21 are closed.
2, and three ribs 53, 53, . . . are provided in the hollow portion S between the base portion 51 and the sealing portion 52.

By the way, the door glasses 11 and 2 of this type of vehicle
1 has a curved shape in which the upper side gradually curves toward the inside of the vehicle, so when opening and closing the door glasses 11 and 21 with the doors 10 and 20 closed, the weather at a certain height of the center pillar is The position of the door glasses 11, 21 in contact with the strip 50 changes depending on how closed the door glasses 11, 21 are.

For example, when closing the opened door glasses 11, 21, the abutting position of the door glasses 11, 21 against the weather strip 50 at the height of the center of the window opening is at the end as shown in FIG. As the door glasses 11 and 21 are raised and closed from the side, the inside of the vehicle, they gradually move toward the center and the outside of the vehicle, as shown in FIG.

At this time, a force acts on the front and rear ends of the weather strip 50 due to the frictional force between the weather strip 50 and the door glasses 11 and 21 in the direction of pushing the weather strip 50 toward the center and toward the outside of the vehicle.

Problems to be solved by the invention However, in the conventional center pillar structure as described above, the engagement point between the retainer 40 and the weather strip 50 is closer to the center than the front and rear ends of the weather strip 50. Therefore, the holding force for the front and rear ends of the weather strip 50 was weak.

Therefore, when closing the open door glasses 11, 21, the weather strip 50 tends to deform so that the front and rear ends are pushed toward the middle and toward the outside of the vehicle, and when the door glasses 11, 21 are completely closed, As shown in FIG. 7, there was a risk that the glass would protrude outside the vehicle from the end surfaces of the door glasses 11 and 21, causing problems such as poor appearance and generation of wind noise.

Further, when the door glasses 11, 21 are closed, the door glasses 11, 21 come into contact with a portion of the sealing portion 52 between the ribs where the elastic force is weak. , 21 causes the rib 53 to bend, resulting in a further weakening of its elasticity.

For this reason, even a slight deviation in the contact area tends to cause poor air/water tightness due to insufficient sealing force, resulting in damage to the weather strip 50 and the door glass 11, 21.
There was also the problem that the tolerance for variation between the two was small and the assembly workability was poor.

Purpose of the invention This invention was created in view of the above problems.It does not protrude beyond the edge of the door glass to the outside of the vehicle, has high air-water tightness, and has a large tolerance for variation between the door glass and the door glass. The purpose is to provide a weather strip for center pillars.

Means for Solving the Problems In order to achieve the above object, this invention provides an engaging portion at least at the front and rear ends that engages with the retainer joined to the outer side of the center pillar, and a base portion and a sealing portion. A plurality of ribs formed across the door glass are arranged in a substantially V-shape in horizontal cross section so as to support the elastic contact area of the door glass in the sealing part from two different directions when the door glass is closed. This is what I did.

Function: The weather strip for a center pillar according to this invention has the above-described structure, so it strengthens the holding force on the front and rear ends, and also reduces the sealing force at the part of the sealing part that comes into elastic contact with the door glass when it is closed. The door glass is hard to deform at the front and rear ends even when the open door glass is closed with the door closed, and the air and water tightness of the sealing part can be improved.

Examples This invention will be explained below based on the drawings. 1st
3 to 3 show an embodiment of this invention. In the drawings, parts or members that are the same or equivalent to the conventional ones are given the same reference numerals, and redundant explanations are omitted.

The center pillar 30 provided between the front door 10 and the rear door 20 (see FIG. 4) is
An inner panel 31 and an outer panel 32 are joined at the front and back, and a welt 60 is attached to each joining site.

A retainer 70 is joined to the outer side of the outer panel 32, and a weather strip 8 made of hollow rubber and having a substantially semicircular horizontal section is attached to the retainer 70.
0 is installed.

These retainers 70 and weather strips 8
0 is configured such that the front and rear ends of the weather strip 80 and the intermediate portion thereof engage with each other.

That is, the retainer 70 includes a base plate part 71 that has a straight horizontal cross section and is joined to the outer panel 32, a front holding part 72 that protrudes from the front end of the base plate part 71 to the outside of the vehicle and extends further forward, and the base plate part 71. It has a rear holding part 73 that protrudes from the rear end to the outside of the vehicle and extends further rearward, and a central holding part 74 that bulges out to the outside of the vehicle at the center of the base plate part 71.

On the other hand, the weather strip 80 is attached to the retainer 7.
0, and an arc-shaped sealing part 82 that bulges out from the base part 81 to the outside of the vehicle and makes elastic contact with the ends of the door glasses 11 and 21.
1 includes three engaging parts 81 at the front and rear and in the middle thereof so as to engage with each holding part of the retainer 70 described above.
a, 81b, and 81c are formed.

Note that a lip 81d that elastically contacts the weight 60 is formed on the front and rear engaging portions 81a, 81b.

Further, in the hollow part S between the base part 81 and the sealing part 82 of the weather strip 80, there is a central rib 83 extending from the base part 81 to the sealing part 82 in the central part in the above direction, and this central rib. Front door glass 1 is arranged in a V-shaped horizontal section in the hollow part S in front of 83.
The first and second ribs 84 and 85 support the elastic contact area from two different directions when the rear door glass 12 is closed, and the second ribs 84 and 85 are also arranged in a V-shaped horizontal cross section on the rear side of the central rib 83 and are used to close the rear door glass 12. Five ribs, ie, third and fourth ribs 86 and 87, are provided to support the elastic contact portion from two different directions.

Next, the operation of the center pillar weather strip constructed as described above will be explained with reference to FIGS. 2 and 3.

Note that both FIGS. 2 and 3 show a cross section of the center pillar portion at a height approximately at the center of the window opening.

In this type of vehicle, the front door 10,
Door glass 11, 2 with rear door 20 closed
1, the position of the door glasses 11, 21 in contact with the weather strip 80 at a certain height of the center pillar changes depending on how closed the door glasses 11, 21 are, as described above. be.

When the opened door glasses 11 and 21 are closed, the door glass 1 initially comes into contact with the intermediate portion between the inside and outside of the sealing portion 82, as shown in FIG.
As the door glasses 11 and 21 are closed, the ends of the weather strips 80 move to the center side of the weather strip 80 and to the outside of the sealing part 82, and at this time, the front and rear ends of the weather strip 80 move toward the outside of the vehicle. Try to push it toward the center and outside of the vehicle.

However, in this weather suit lip for center pillar, the holding parts 72, 73 at the front and rear of the retainer 70
and the front and rear engaging portions 81 of the weather strip 80
a and 81b, the front and rear ends of the weather strip 80 are not easily deformed when the above-mentioned force is applied, unlike in the conventional case, and the weather strip 80 is not deformed. Even when the door glasses 11 and 21 are closed, the door glass 1 is closed as shown in FIG.
Stops inside the car from the end faces of 1 and 21.

Moreover, the door glasses 11 and 2 in the sealing part 82
1. The contact area when closed is two ribs, that is, the front side of the center rib 83 is the first and second ribs 84 and 8.
5. The third and fourth ribs 8 are located behind the central rib 83.
6 and 87 are supported from different directions, and these ribs do not bend when the door glasses 11 and 21 are closed like in the past, so the sealing force in these parts is strong and it is difficult to assemble them. Some variation can be tolerated.

In the above embodiment, the middle part of the sealing part 82, which the door glasses 11, 21 first come into contact with when closing the open door glasses 11, 21, and the middle part of the first and third ribs 84, 86 and are arranged substantially in parallel as shown in FIG. Therefore, the sealing part 8
2 is easily bent when the door glasses 11, 21 come into contact with each other, the frictional resistance between the weather strip 80 and the door glasses 11, 21 is small at the time of contact, and the door glasses 11, 21 can be easily opened and closed. Effects As explained above, the weather strip for a center pillar according to this invention is provided with an engaging portion at least at the front and rear ends that engages with the retainer joined to the outer side of the center pillar. The holding force against the weather strip is strengthened, and the front and rear ends of the weather strip are less likely to deform.

Therefore, even when closing the open door glass with the door closed, the weather strip does not protrude beyond the end surface of the door glass to the outside of the vehicle.

In addition, the plurality of ribs formed across the base and the sealing part are arranged so that the horizontal cross section is approximately V-shaped so as to support the elastic contact area of the sealing part when the door glass is closed from two different directions. Because they are arranged in a mold, the sealing force when closing the door glass can be strengthened.
Some variation during assembly can be tolerated.
