Abstract

PURPOSE:To realize simple and certain prevention of water infiltration into a chamber from around the terminal of a waist part and also improve quality of a vehicle by interposing an extension part of a weather strip between an extension part of a braid and a door waist part. CONSTITUTION:A waist part W of a door 1, formed by an outer panel 1a and an inner panel 1b, is equipped with a waist braid 4, which is formed by a braid main body 4a and end caps 4b fitted to front and rear ends of said main body 4a, while the upper end of the end cap 4b is extended 4c downward. A weather strip 6, a base part 6a of which is fitted to the peripheral part of the door 1, is configured such that a seal lip 6b extended from the base part 6 is put in elastic contact with the peripheral part of an opening of a car body 8 to seal off a compartment R from the outside E of the car at the time of door closure. The extension part 6c of the weather strip 6 is interposed for support between the extension part 4c of the braid 4 and the waist part W.

Description

DETAILED DESCRIPTION OF THE INVENTION a. Field of Industrial Application This invention relates to a door waist seal structure for an automobile.

b. Prior Art In general, the door waist portion of a rear door of an automobile is as shown in FIGS. 1 and 2, as shown in, for example, Japanese Utility Model Application No. 55-175520. In both figures, reference numeral 1 denotes a rear door panel (hereinafter simply referred to as a door), which is formed into a box shape by a rear panel 111 and an inner panel 1b, and is designed to accommodate the door glass 2. 4 is attached to the waist portion W of door 1 in its longitudinal direction (i.e., in the longitudinal direction of the vehicle)
A door weather strip (hereinafter referred to simply as a weather strip) has a base 6 attached to the periphery of the door 10, and a sealing lip 6b is in elastic contact with the opening periphery of the vehicle body 8 when the door is closed. The upper end of this weather strip 6 extends parallel to the waist molding 4.

However, in such a structure, rainwater and car wash water flow from the gap C between the opening periphery of the vehicle body 8 and the waist molding 4 as shown by the arrow, and the rainwater and car wash water flow into the door waist portion W and the weather strip base 68. There is a risk that the vehicle may enter the interior room R. For this reason, an adhesive is applied between the back surface of the weather string base 68 and the door waist portion W to achieve a complete seal, but this involves the troublesome work of having to go to the trouble of applying adhesive. Moreover, since it involves the troublesome work of wiping off the adhesive that has protruded (unless the adhesive is applied to the extent that it protrudes, poor adhesion will occur and a complete seal cannot be achieved), improvements are needed in manufacturing operations. ing.

Furthermore, when the door l is opened, the door waist portion W becomes completely exposed, which impairs the quality of the exterior appearance and makes the user feel uneasy about the quality of the vehicle.

C0 Purpose This invention has been made in view of the conventional demands and problems, and it is an object of the present invention to provide a door waist part sealing structure that easily and reliably prevents water from entering from the end of the waist part and improves the appearance quality. It is an object.

d. Configuration In order to achieve the above object, the present invention extends upward from the base of the weather strip attached to the peripheral edge of the door panel along the door waist portion, and the weather strip of the west molding By extending the terminal portion facing the upper end portion downward and sandwiching the weatherstrip extension portion between this molding extension portion and the door waist portion, the weatherstrip can flow in through the gap between the waist molding and the opening peripheral portion of the vehicle body. Water is prevented from entering between the base of the weather strip and the door waist part, and all of the water is drained out of the vehicle along the path between the base of the weather strip and the seal lip that makes elastic contact with the periphery of the opening in the vehicle body. It is something. Therefore, since the door waist portion is covered by the molding extension, the door waist portion is not exposed when the door is opened, and the appearance quality can be improved.

e. Embodiment In FIG. 3, the same parts as the conventional one are given the same reference numerals.The waist part W of the door 1 formed by the outer panel 13 and the inner panel 1h has a waist molding along its longitudinal direction. 4 is attached by a means such as a clip (not shown). This waist molding 4 includes a shiny molding body 48 made of stainless steel or the like, and a molding body 48 made of stainless steel or the like. It consists of a resin end camp 4b attached to the front and rear ends of the end cap 4b, and the upper end of this end cap 4b extends downward.
c.

Peripheral part 9 base of door l 6. When the weather strip 6 is attached, the seal lip 6b extending from the base 68 comes into elastic contact with the opening periphery of the vehicle body 8 when the door is closed.
I try to seal it.

This weather strip 6 extends upward from its base 6a to the waist portion WK of the side door 1.

Due to this structure in which the extension part 4c of the waist molding 4 and the waist part W sandwich the extension part 6c of the weather strip 6, the opening periphery of the vehicle body 8 and the waist molding 4 are As shown by the arrow from the gap C between the gaps, rainwater, car wash water, etc. will flow into the waist part W and the weatherstrip 6 (IIIK) even in A7, and the extension part 6c of the weatherstrip 6 will not enter the waist part W and the weatherstrip 6 (IIIK) as in the conventional case. 4, the water is suppressed by the extension 4c of the weather strip 6c and the seal lip 6b.
F) will be ejected from the vehicle. (In other words, in areas where the molding extension part 4e is not formed, the weather strip 6 is oriented vertically, making it convenient for drainage.) Furthermore, the door waist part W is formed by the waist molding extension part 4c. Since the door waist portion W is covered with the weather strip 6, it is not exposed when the door is opened and the appearance quality is significantly improved.
The extension part 6c is formed in an inverted J shape, and its free end part 6d is hooked on the door waist part W, and is suppressed from above and from the side by the extension part 4c of the waist molding 4, further increasing the gripping property. At the same time, the ability to prevent water from entering is further improved.

In both examples, extensions were formed on the end camp of the waist molding, but this is most suitable when the molding body is extruded (the extruded molding body is cut to a predetermined length). However, when using an integrally molded waist molding or when the length of the end camp is short, it is common to install an end camp for terminal processing. A downward extension can also be formed. Furthermore, although the molding main body made of stainless steel is shown in the embodiment, it goes without saying that the present invention can also be applied to a case where the resin and the glitter film are integrally extruded.

In addition, in this invention, a large end cap with a structure having an independent decorative function and a design that has a sense of continuity with the main body of the waist molding are collectively referred to as one waist molding.

f. Effects According to the present invention, it is possible to easily and reliably prevent water from entering the room from the waist terminal case.
Unlike conventional methods, this method does not require adhesive application work or wiping off protruding adhesive, resulting in a significant reduction in manufacturing man-hours.

In addition, the quality of the appearance when the waist door is opened is also improved, and the quality of the vehicle can be improved.
