Description

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

Generally, an automobile door is equipped with a door weather strip 3 that extends from the outer periphery of the door sash 1 to the outer periphery of the door body 2, as shown in FIG. It is placed close to the edge to seal the interior and exterior of the vehicle. When installing the door weather strip 3, as shown in FIG. 2, the weather strip base portion 3a is usually attached to the mounting groove 1a formed on the outer periphery of the door sash 1. The portion that is fitted and fixed and arranged on the outer periphery of the door body 2 is fixed by penetrating the clip 4 attached to the base portion 3a into a mounting hole formed in the door panel, specifically, the door inner panel 2a. That's what I do.

The door weather strip 3 is attached to the door as described above, but if we pay special attention to the attachment position of the door weather strip 3 on the door body 2 side, rainwater that enters the door body 2,
Because it is necessary to form a drain for water such as car wash water, and to install a door hinge, door lock device (none of which are shown), etc., as shown in FIG. It is set at the periphery of the outer periphery of the door body 2 on the passenger compartment side. Therefore, in the vicinity of the door waist, as shown in FIG. 2, a portion P is created in the door weather strip 3 whose placement position changes from an extension of the door sash 1 to the passenger compartment side.

When fixing the portion of the door weather strip 3 whose placement position changes, the portion of the door weather strip 3 offset from the extension portion 1a of the door sash 1 can be fixed with the aforementioned clip 4; At the portion where the door sash extension 1a and the door weather strip 3 are back to back on the inner and outer surfaces of the inner panel 2a, the clip tip interferes with the door sash extension 1a, making it impossible to secure the clip 4. Put it away. Therefore, in the past, adhesives were used to fix the changed parts.
The door had been fixed with adhesive, but the door could not be closed until the adhesive had completely cured.
On a vehicle body assembly line, not only is there a disadvantage in terms of work space, but the door also becomes an obstacle when assembling other functional parts, impairing assembly work efficiency. Therefore, the present applicant first applied for the
In No. 116258, we proposed a mounting structure using resin clip members to solve problems caused by adhesives. That is, as shown in FIGS. 2 and 3, there is a retainer portion 11 on one side that holds down the side edge of the base portion 3a of the door weather strip 3 over a relatively long range.
and a step portion 2b formed on the door inner panel 2a by a clip member 10 which integrally has a clip portion 12 on the other side that penetrates and engages with a mounting hole formed at a position offset from the door sash extension portion of the door inner panel 2a. In cooperation with the door weather strip 3, a changing portion P on the periphery of the door weather strip 3 on the passenger compartment side is held.

By the way, since the door weather strip 3 is restrained and held in a predetermined position by the clip member 10 and the panel stepped portion 2b, when the stepped portion 2b is formed on the door inner panel 2a,
Although the door weather strip 3 can be accurately held in a predetermined position, due to the manufacturing of the door panel, the stepped portion 2b is
If the door weather strip 3 cannot be formed, or if the stepped portion 2b is not formed, the door weather strip 3 will be held only by the clip member 10, and the door weather strip 3 will be held by the clip member 10, and the door weather strip 3 may be accidentally moved by hand or the door may be repeatedly opened and closed. The strip 3 tends to move outward in the vehicle width direction, which causes a seal failure between the door and the opening edge of the vehicle body when the door is closed, resulting in a problem that impairs the basic performance of the door area.

This invention focuses on the problems mentioned above, and when fixing the part where the placement position of the door weather strip changes, in addition to the clip fastening on the inside in the width direction, Also, by holding the door weather strip with a clip member, it is possible to fix the door weather strip even on a door inner panel where a protrusion is not formed. The aim is to improve installation reliability.

An embodiment of this invention is shown below in Figures 4 to 6.
This will be explained with a diagram. As illustrated in FIG. 4, the installation position of the door weather strip 3 is
From an extension of At the offset position, on the vehicle interior side, it is held by an inner clip member 10a, and on the vehicle outer side, it is held by an outer clip member 13 provided opposite to the clip member 10a. . The inner clip member 10a made of resin and provided on the vehicle interior side has a structure that integrally includes a plate-shaped retainer portion 10b and a clip portion 12, and is attached to the door weather strip at a predetermined position by means similar to the conventional method. The outer clip member 13, which is also made of resin, supports the outer edge of the base portion 3a of the door weather strip 3 on the outer side of the vehicle.
A plate-shaped retainer portion 14 for holding the device over a relatively long range is extended from a rising portion 16 erected on the base portion 15 through a bent portion 19 in a hook shape. The height of this rising portion 16 is approximately equal to the height of the side edge of the base portion of the weather strip 3 on the outside of the vehicle. Further, a reinforcing rib 17 is provided between the base portion 15 and the rising portion 16. Further, the lower surface of the base portion 15 is integrally provided with a clip portion 18 that penetrates and engages with a mounting hole formed in the door inner panel 2a.
The clip portion 18 can be fitted into a mounting hole formed on the outer side of the door inner panel 2a, so that the outer edge of the base portion 3a can be securely held by the retainer portion 14. On the other hand, other parts of the door weather strip 3 disposed on the door body 2 side are fixed to the door inner panel using a clip 4 attached to the center of the door weather strip base 3a, as in the conventional case. Install it on 2a.

As described above, according to this invention, the portion of the door weather strip disposed on the outer periphery of the door body that overlaps with the door sash extension can be moved to a position on the inside of the vehicle that is offset from the door sash, and the door weather strip is It is held and fixed by a pair of inner and outer resin clip members at a position on the outside of the vehicle that is almost opposite to the above-mentioned position, and the retainer portion of the pair of inner and outer clip members is formed into a plate shape to provide good curve followability. On the other hand, since the height is approximately equal to the height of both edges of the base portion of the door weather strip, both edges of the door weather strip can be held securely and firmly.

Therefore, there is no need to accidentally move the door weather strip by hand or when the door is repeatedly opened and closed, and there is no need to form a protrusion on the door inner panel. It can be expected to have an excellent practical effect of being easy to manufacture and reducing costs.
