Description

[Detailed Description of the Invention] The present invention relates to a mounting structure for a door weather strip on an automobile door.

Generally, as shown in FIG. 1, an automobile door is equipped with a door weather strip 3 extending from the outer periphery of the door sash 1 to the outer periphery of the door body 2, and the door weather strip 3 is attached when the door is closed. It is formed in close contact with the outside edge of the vehicle body opening to seal the interior and exterior of the vehicle. When installing the door weather strip 3, as shown in FIGS. 2 to 5, the portion of the door weather strip 3 disposed on the outer periphery of the door sash 1 is inserted into the mounting groove 4 formed on the outer periphery of the door sash 1. base part 3 of pool 3
a is fitted and fixed, and the portion disposed on the outer periphery of the door body 2 has a clip 5 attached to the base portion 3a that is penetrated into the mounting hole 7 formed in the door panel 6, specifically the door inner panel 6a. I'm trying to fix it.

By the way, the door weather strip 3 is attached to the door as described above, and the attachment position of the door weather strip 3 on the door body 2 side is designed to prevent rainwater from entering the door body 2 and car washing. In order to form a drainage part for water, etc., and to install door hinges, door lock devices (all not shown), etc., the second
As shown in the figure, it is offset toward the vehicle interior from the extension of the door sash 1, and is set at the peripheral edge of the outer periphery of the door body 2 on the vehicle interior side. Therefore, in the vicinity of the door waist, as shown in FIG. 2, a portion P is created where the position of the door weather strip 3 intersects from the extension of the door sash 1 to the passenger compartment side. When fixing this portion of the door weather strip 3 whose placement position changes, it is possible to fix the above-mentioned clip 5 at the portion where the door weather strip 3 is offset from the extension 8 of the door sash 1. 6a, where the door sash extension 8 and the door weather strip 3 are back-to-back, the tip of the clip 5 interferes with the door sash extension 8, so the clip 5
It becomes impossible to stop it. Even if a hole for inserting the clip is made in the door sash extension 8 and the glass run rubber 9 fitted to the door sash 1, and the clip 5 can be secured as shown by the chain line in FIG. 4, the tip of the clip 5 will not door glass 10
It is impossible to eliminate the possibility that the door glass 10 may interfere with the movement of the door glass 10 and interfere with the lifting and lowering of the door glass 10. Therefore, generally speaking, the portion of the door weather strip 3 whose position changes is fixed by adhesively fixing it with an appropriate adhesive 11, as shown in FIG. Therefore, when fixing the door weather strip 3, there is a problem that the door cannot be closed until the adhesive 11 is completely cured. That is, if the door is closed without the door weather strip 3 being completely adhered,
The door weather strip 3 may peel off due to the deflection of the door weather strip 3 or the reaction force when it comes into close contact with the opening edge of the vehicle body, resulting in poor installation. Leaving the door open for such a long time is not only disadvantageous in terms of work space, but also has the disadvantage that the door becomes an obstacle when attaching other functional parts, impairing the ease of assembly.

As a means to solve such problems in the conventional door weather strip mounting structure, the applicant first developed a method using adhesive to fix the parts of the door weather strip where the installation position changes. We have proposed a mounting structure using a clip member that can avoid interference with the door sash, door glass, etc. That is, according to this mounting structure, as shown in FIGS. 6 and 7, the clip member C includes a retainer portion 12 on one side that presses the side edge of the base portion 3a of the door weather strip 3, A clip part 14 is integrally provided on the other side of the door inner panel 6a to penetrate and engage with a mounting hole 13 formed at a position offset from the door sash extension part 8.
the side edge of the base portion 3a into the retainer portion 12.
This is intended to improve the workability and the installation reliability of the door weather strip by firmly clamping the door weather strip (Utility Application No. 116258/1983). However, even with this mounting structure, the retainer part 12 is attached to the base part 3a of the door weather strip 3.
Because the area where the side edges can be directly held is limited,
There is also a limit to the mounting reliability of the door weather strip 3, and in order to hold the side edge of the base portion 3a of the door weather strip 3 over a wide area, the clip member C' itself must be made larger. However, there is a problem that the cost increases accordingly. Furthermore, when holding the clip member C' over a portion P where the placement position of the door weather strip 3 changes, the shape of the retainer portion 12 of the clip member C' is adjusted to the degree of curvature of the door weather strip 3. Therefore, it becomes necessary to form the clip member C' appropriately, which makes the molding of the clip member C' troublesome, and there is a problem that it lacks versatility.

The present invention has been developed based on the above-mentioned viewpoints, and its purpose is to provide elastically deformable legs at both ends of the retainer portion of the clip member to improve the arrangement of the door weather strip. When fixing the part whose installation position changes, the side edge of the base part of the door weather strip can be held over a wide range, and the leg part can be used to hold the side edge of the base part at the curved part of the door weather strip. To provide a door weather strip mounting structure which further improves the mounting reliability of the door weather strip by making it possible to securely hold the door weather strip.

Hereinafter, the present invention will be described in detail based on embodiments shown in the accompanying drawings.

In the embodiment shown in FIGS. 8 to 10, the position of the door weather strip 3 changes from the extension of the door sash 1 to the outer periphery of the door main body 2 on the passenger compartment side, and the door weather strip 3 is installed at a position on the door inner side. A portion of the inner and outer surface of the panel 6a that overlaps with the door sash extension 8 is held by a clip member C fixed through the door inner panel 6a at a position offset from the door sash extension 8.

In this embodiment, the clip member C is the ninth
As shown in the figure, a retainer part 1 presses down the side edge of the base part 3a of the door weather strip 3 on one side.
2, and a clip part 14 on the other side that penetrates and engages a mounting hole 13 opened at a position offset from the door sash extension part 8 of the door inner panel 6a, and is integrally molded in a substantially T-shape. The retainer section 12 is composed of a base section 15 and leg sections 16 that extend elastically along the longitudinal direction of the door weather strip 3 using both ends of the base section 15 as fulcrums. 16 is the base 1
5, it can be bent and deformed in the vertical direction (direction of arrow X) and in the horizontal direction (direction of arrow Y) along the outer peripheral surface of the door body 2. To hold the side edge of the base portion 3a of the door weather strip 3 using this clip member C, insert the clip portion 14 into the mounting hole 13.
Push the side edge of the base part 3a into the retainer part 1.
At this time, since the leg portions 16 of the retainer portion 12 extend along the longitudinal direction of the door weather strip 3, the door weather strip 3 may be firmly attached. Not only is the side edge of the base portion 3a held over a wide range by the clip member C, but also because the leg portion 16 is formed to be elastically deformable, the door weather strip 3 can only be bent in the vertical direction. However, the above-mentioned leg portions 16 also apply to the portion P where the arrangement position of the door weather strip 3 changes, that is, the portion where the door weather strip 3 curves in the left-right direction along the outer peripheral surface of the door body 2. is door weather strip 3
The door weather strip 3 is elastically deformed to follow the bending of the door weather strip 3, and the side edge of the base portion 3a of the bent portion of the door weather strip 3 can be held. Depending on the size of the clip member C, the clip portion 14 may interfere with the reinforcing portion 1a formed overhang on the side of the door sash 1. A clip portion 1 as shown in FIG. 10 is attached to the reinforcing portion 1a that does not contribute to the guide.
4 may be formed by cutting out the relief portion 1b. On the other hand, other parts of the door weather strip 3 disposed on the door body 2 side are fixed in the same manner as before, for example, as shown in FIG. It is attached to the door inner panel 6a by a clip 5 attached to the door inner panel 6a.

As explained above, according to the door weather strip mounting structure according to the present invention, the portion of the door weather strip disposed on the outer periphery of the door body that overlaps with the door sash extension is offset from the door sash. Since it is held and fixed by a clip member that is fixed to the door panel at a fixed position, there is no problem of interference with the door sash, and installation workability is improved compared to conventional adhesive types. The door can be closed without risking loss of work space on the car body assembly line. Furthermore, the retainer portion of the clip member is provided with leg portions that can be elastically deformed from both ends of the base along the longitudinal direction of the door weather strip using the base as a fulcrum. The edge can be held over a wide range without increasing the size of the clip member itself, and the legs can be used to hold the door weather strip even on curved parts where the placement position of the door weather strip changes. It can elastically deform to follow the bending of the door weather strip and reliably hold the side edge of the base part of the door weather strip, which improves the installation reliability of the door weather strip and is highly versatile. It has great effects.
