Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a partition structure for installing a partition glass of an automobile door.

[Prior Art] In the case of a four-door car with a sash, the rear door has a door glass that is guided up and down by a main sash 1, a center sash 2, and a lower sash inside the door body (not shown), as shown in Figure 1. A partition glass 4 is fixedly disposed in an opening portion surrounded by the center sash 2, the main sash rear side 1a, and the door waist portion at the rear side of the main sash 3. This partition glass 4 is fixed at its periphery via a partition weather strip 5.
The lower part of the partition weather strip 5 is a waist molding 6 that decorates the door waist part.
The cross-sectional shape is different from other parts due to the arrangement of the parts. As shown in Figure 3, the parts attached to the sashes 1a and 2 are attached to the sashes 1a and 2.
The partition glass 4 is fitted into the vehicle interior,
The cross section is symmetrical about the center line of the glass clamp so that it can be clamped from the outside. On the other hand, the lower part
As shown in the figure, the center sash 2 and the rear main sash 1 are located inside the door waist opening Wa.
The seal lip 5a is fitted into a holder 7 having a channel-shaped cross section connected to the door a, and a seal lip 5a that is in close contact with a door finisher 10 covering the door inner panel 8 is integrally molded on the side of the door facing the passenger compartment. Then, a seal lip 6a molded onto the shoulder part of the waist molding 6 attached to the waist part of the door outer panel 9 is attached to the partition glass 4.
It is placed in close contact with the outer surface of the vehicle to seal the interior and exterior of the vehicle.

On the other hand, a welt seal 13 consisting of a welt part 13a that fits into the flange 12 and a hollow seal lip 13b that is integrally molded on the outer side surface of the welt part 13a is attached to the peripheral flange 12 of the vehicle body opening 11 to which the rear door D is attached. However, when the door is closed, a door weather strip 14 attached to the entire periphery of the door and this welt seal 13 form a double seal to improve sealing performance and sound insulation properties.

Similar structures around the partition glass mounting part of the rear door and around the rear door are described, for example, in Japanese Unexamined Patent Publication No. 167514/1983 and Nissan Service Bulletin.
It is shown in the introduction of the Y30 series car.

By the way, in the case of automobiles, in order to improve lateral visibility and improve the feeling of openness in the interior, the door waist line WL is set to a height that does not interfere with the retraction of the door glass 3 than the standard height shown by the chain line in Figure 1. It is required to lower the door sash as much as possible to the position shown by the solid line in the same figure, thereby increasing the area of the door opening and widening the side visibility.

On the other hand, at the rear welt part of the vehicle body opening 11, as shown in FIG. Existing. Since this intersection 17 receives rear suspension input, if the bend R is made small, the strength of the vehicle body will be impaired due to stress concentration, so it is necessary to set the bend R relatively large. Therefore, as mentioned above, when lowering the door waist line WL to expand the lateral visibility of the door, the main sash rear side 1a
The intersection point 17 is exposed through the partition glass 4 at the corner formed by the door waist line WL and the door waist line WL, and the appearance is seriously spoiled. In addition to this problem in terms of appearance, the fact that the intersection point 17 is exposed means that the peripheral flange 12 is exposed at the intersection point 17.
Since the welt seal 13 attached to the main sash is not in close contact with the rear side portion 1a of the main sash or the door inner panel 8, the above-mentioned double seal cannot be obtained, and furthermore, the height position of the intersection 17 is close to the ears of the rear seat occupant. Because of this, the problem arises that the desired sound insulation effect cannot be obtained.

[Purpose of the invention]

The present invention has been developed in view of the conventional situation, and even when the door waist line is lowered, the dogleg-shaped intersection of the rear pillar at the edge of the vehicle body opening and the front side of the rear wheel house is exposed at the corner of the partition glass. It is an object of the present invention to provide a door partition structure that can prevent noise and ensure sound insulation at the intersection.

[Structure of the invention]

In order to achieve the above object, in the present invention, a corner piece body having a substantially triangular side surface is provided at the corner formed by the rear side and lower side of the partition weather strip in which the partition glass is fitted and fixed. The corner piece body is integrally molded and fixed at the corner formed by the rear side of the main sash and the door inner panel waist portion on the vehicle interior side of this corner piece body, and aligned with the side of the main sash and the side of the door inner panel to form the vehicle body opening. It has an overhang that comes into close contact with the welt seal attached to the edge flange.

〔Example〕

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings, in which the same parts as those of the conventional structure are denoted by the same reference numerals.

In Figures 4 to 6, 5 is the main sash 1.
A partition weather strip is fitted onto the center sash 2 and the holder 7 connected to the main sash rear side 1a and the center sash 2 shown in FIG. As shown, a corner piece main body 20 having a substantially triangular side surface is integrally formed at a corner formed by the rear side and lower side of the partition weather strip 5. Further, a projecting portion 21 is integrally formed on the side surface of the corner piece body 20 on the side of the vehicle interior. This projecting part 21 is formed in a substantially triangular shape on the side so that it can be placed at the corner formed by the rear side part 1a of the main sash 1a and the waist part of the door inner panel 8, and its thickness is set on the passenger compartment side of the main sash 1a. and the side surface of the door inner panel 8, and is arranged to be in close contact with a welt seal 13 attached to a peripheral flange 12 of the vehicle body opening. Further, a protruding piece 22 that engages with a groove 10a formed at the edge of the waist portion of the door finisher 10 is integrally molded on the lower front end of the projecting portion 21, and the protruding piece 22 and the door finisher 10 are connected to each other. The engagement prevents the projecting portion 21 from moving freely.

Further, a groove 24 is formed on the back of the part of the partition weather strip 5 where the corner piece main body 20 is integrally molded, which engages with a bracket 23 fixed to the approximate center of the rear side portion 1a of the main sash. The corner piece body 20 is reinforced by the bracket 23 to prevent it from being bent or deformed in the vehicle width direction.

According to the structure of the above embodiment, even when the door waist line WL is lowered from the chain line position to the solid line position in the figure to expand the side visibility as shown in Figure 1, the partition weather strip 5 Since a corner piece main body 20 having a generally triangular side surface is integrally molded at the corner formed by the rear side part and the lower side part, the rear pillar 15 and rear wheel house 16 at the rear waist part of the vehicle body opening 11 are integrally formed. The dogleg-shaped intersection 17 with the front side portion can be hidden by the corner piece main body 20, and the appearance will not be impaired.

In addition, since the overhanging part 21 integrally molded on the vehicle interior side of the corner piece body 20 is in close contact with the welt seal 13 attached to the flange 12 at the doglegged intersection 17, the rear part of the vehicle body opening 11 is Even in the side waist portion, a double seal between the door weather strip 14 and the welt seal 13 can be ensured, and a reduction in sound insulation performance can be avoided.

The embodiment shown in FIGS. 7 and 8 is a door inner panel 8.
The present invention is applied to a rear door in which the waist flange 8a of the door outer panel 9 and the waist flange 9a of the door outer panel 9 are respectively bent downward.
Holder 7A formed by these flanges 8a and 9a
holds the lower side of the partition weather strip 5. Since the door finisher 10 comes to be close to the waist part of the door inner pulse 8 due to the downward molding of the waist flange 8a, the protruding piece 22 at the front end of the overhanging part 21 is formed flat into a tongue shape. It is adapted to engage with a groove 10a on the edge of the waist portion of the finisher 10.

In the embodiment shown in FIG. 9, the projecting portion 21A is molded separately from the corner piece main body 20. Similar to the embodiment shown in FIGS. 7 and 8, this projecting portion 21A has a tongue-like projection 22A formed at its lower front end.
It is designed to engage with a groove 10a on the edge of the waist portion of the door finisher 10 shown in FIG. The mounting piece 25 is fixed by being crimped between the inner wall of the main sash rear side 1a and the rear side of the partition weather strip 5 fitted to the main sash rear side 1a.

By separately molding the overhanging portion 21A in this way, not only can the degree of freedom in coloring the overhanging portion 21A be obtained, but also the material can be arbitrarily selected from rubber, resin, etc., and in particular, if it is made of resin, it will be even better. Since the degree of freedom in coloring is expanded, the projecting portion 21A can be harmonized with the color of the vehicle interior, which has the advantage of improving the appearance of the vehicle interior.

〔Effect of the invention〕

As described above, according to the present invention, even when the waistline of the rear door is lowered as much as possible to expand the lateral visibility, the corner formed integrally with the rear corner of the partition weather strip can be used. The piece body can hide the dogleg-shaped intersection where the rear pillar at the rear waist portion of the vehicle body opening and the front side of the rear wheel house are joined, improving the appearance of the vehicle. The overhang attached to the interior side comes into close contact with the welt seal attached to the flange at the intersection, allowing the seal line to be continuous around the periphery of the vehicle body opening, thus improving not only sealing performance but also sound insulation. This has a great practical effect in that it can be secured.
