Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention relates to an improvement in the seal structure at the connection between the upper end of a partition sash that defines a glass opening of an automobile door and a main sash.

BACKGROUND ART FIG. 3 shows, for example, a left rear door 1 of an automobile, and a partition sash 2 has a glass opening surrounded by a main sash 3 fitted into an opening for a door glass 4 that can be opened and closed. It is arranged along the vertical direction to separate the opening for the partition glass 5 which is in a dead state, and its lower end is fixed inside the door panel 6, and its upper end is connected to the main sash 3 in a T-shape. Connected and fixed.

FIG. 4 is an exploded perspective view showing a conventional sealing structure at the upper end of the partition sash 2 at the connection part with the main sash 3 (section A in FIG. 3). A glass run fitting groove 9 and a gasket fitting groove 10 are installed so as to hold the glass launch channel 7 whose four edges are in sliding contact and the gasket type weather strip 8 which clamps and fixes the partition glass 5 back to back to each other. It has a substantially H-shaped cross-sectional shape. Then, an L-shaped bracket 12 is fixed to the gasket fitting groove 10 side surface of the central partition wall 11 by welding or the like, and is attached to the main sash 3 via a screw (not shown) that is screwed into the screw hole 12a. ing.

Here, between the upper end of the partition sash 2 and the main sash 3, there is a partition sash 2.
Synthetic resin end cap 13 fitted to the upper end
are held in place to create a seal between the two and improve their appearance.

Specifically, the end cap 13 covers the outer side end surface of the partition sash 2, covers the outer side spacer portion 14 which is clamped between it and the main sash 3, and covers the end surface of the partition sash 2 on the side of the passenger compartment. In addition, a spacer portion 15 on the vehicle interior side which is also pressed between the main sash 3 and both spacer portions 1
4 and 15 and connected to the central partition wall 11 of the partition sash 2;
6 The leg portion 1 forms a substantially U-shape together with the lower portion and fits into the glass run fitting groove 9 of the partition sash 2.
7, 18, and a substantially triangular side wall portion 19 that stands upright from the inner edge of the outer side spacer portion 14 to the partition wall portion 16 and has a substantially triangular shape. Main edge is Satsushi 3
The partition wall portion 16 is thinned so as to be in elastic contact with the inner surface, and a substantially rectangular cutout portion 20 is formed in the upper portion of the partition wall portion 16 on the compartment side.

On the other hand, a thin plate-shaped seal lip 21 is formed elongated in the vertical direction at the upper part of the glass launch channel 7 facing the partition wall 16 on the passenger compartment side, and a seal lip 21 in the form of a thin plate is formed in an elongated manner in the vertical direction. There is also a thin plate-like seal lip 22 on the top.
is formed to be elongated in the vertical direction. Both seal lips 22 are attached to the end cap 13.
In the assembled state, as shown in FIG. 5, their distal edges abut each other through the notch 20, so that they are in close contact with each other.

That is, the side wall 19 of the end cap 13 on the outside of the vehicle prevents raindrops and car wash water from entering into the gap created at the boundary between the glass launch channel 7 and the gasket type weather strip 8 at the upper end of the partition sash 2. On the other hand, on the passenger compartment side, the glass launch channel 7 and the gasket type weather strip 8 are made substantially continuous by abutting both seal lips 21 and 22 to ensure sealing performance. There is.

Problems to be Solved by the Invention However, when the glass launch channel 7 or the gasket type weather strip 8 is actually attached to the corner portion consisting of the main sash 3 and the partition sash 2, variations in the main sash 3, etc. Due to variations in the assembly of the glass launch channel 7, etc., the bottoms of these parts tend to be slightly lifted from the corners, that is, the upper ends of the partition sashes 2 tend to move away from the partition walls 16 of the end caps 13. There is a tendency to pull.

Therefore, in the above-mentioned conventional device in which the distal edges of both seal lips 21 and 22, which are parallel to each other due to design, are butted against each other, they are separated at the upper ends, creating a gap 23, as shown in FIG. If the car wash water was hit hard from the side, water would seep into the passenger compartment.

Means for Solving the Problems In order to solve the above problems, the seal structure of the upper end of the partition sash according to the present invention has the following features:
The sealing lip of the glass launch channel and the sealing lip of the gasket type weather strip are characterized in that the tip edges of at least one of them are extended in a tapered shape, and the tip edges of both sealing lips are closely overlapped with each other.

Function: Even if the bottom of the glass launch channel or gasket type weather strip is pulled away from the end cap partition due to variations during assembly, the close contact between both seal lips is maintained and no gap is created. do not have. Also, since they overlap each other, the seal becomes even more reliable.

Embodiment FIG. 1 shows an embodiment of the seal structure according to the present invention. This embodiment has the same basic structure as the seal structure shown in FIG. are given the same reference numerals, and duplicate explanations will be omitted.

That is, in the seal structure of this embodiment, the tip edge 21a of the thin plate-shaped seal lip 21 provided at the upper part of the bottom of the glass launch channel 7 on the passenger compartment side has a taper that becomes wider as it goes upward. The tip edge 22a of a thin plate-shaped seal lip 22 is extended into a shape and is provided at the upper part of the bottom of the gasket-type weather strip 8 on the passenger compartment side.
Similarly, it is formed in a tapered shape that becomes wider as it goes upward. Moreover, one seal lip 21 is formed slightly closer to the vehicle interior and the other seal lip 22 is formed slightly closer to the outer side of the vehicle compared to the conventional one so that they overlap each other.

Therefore, in the assembled state, as shown in FIG.
The first end edge 21a and the seal lip end edge 22a of the gasket type weather strip 8 protrude relatively largely from the notch 20 of the end cap 13 toward the other side, and overlap each other to a sufficient extent and are in close contact with each other. Therefore, even if there is some variation during assembly, no gap will be created between the two.

Note that the lower edge 2 of the notch 20 of the end cap 13
If 0a is a tapered surface that follows the tapered shape of the seal lips 21 and 22, the partition wall portion 16
Even the slightest gaps caused by the plate thickness can be completely eliminated.

Although not shown, both seal lips 2
It is also possible to construct such that only either one of 1 and 22 is extended into a tapered shape and overlapped with each other.

Effects of the Invention As is clear from the above explanation, according to the seal structure of the upper end of the partition sash according to the present invention, the glass launch channel and gasket type weather strip are always connected regardless of variations during assembly. A continuous seal can be formed, and rainwater, etc., can be reliably prevented from seeping into the vehicle interior.
