It is attached to the vehicle door trim 1 via the.

[0004]

[Problems to be solved by the device]

 However, in the conventional mounting structure in which the door inner seal 3 is fixed to the automobile door trim 1 via the resin bracket 2, first, when the resin bracket 2 is molded by an injection molding die, the resin bracket 2 is In order to form the mounting hole 4, as shown in FIG. 5, a mold structure having a slide core 8 between the fixed side mold 6 and the movable side mold 7 is required, and the mold structure of the injection molding mold is required. It has been pointed out that there is a problem that it becomes complicated and maintenance is difficult.

Further, in the fixing method of inserting the locking claw 5a of the door inner seal 3 into the mounting hole 4 of the resin bracket 2 and bending the door inner seal 3, an external force directed from the upper side to the lower side is applied to the door inner seal 3. In this case, since the stress is applied to the lower side of the locking claw 5a, the locking claw 5a is easily deformed, and the external force directed downward in the door inner seal 3 is applied except for the position where the locking claw 5a is set. However, it has been pointed out that since it is relatively weak against external force in the downward direction, reliable mounting strength cannot be expected.

The present invention has been made in view of such circumstances, and in a door inner seal attachment structure for attaching a door inner seal to a door trim via a resin bracket, a resin bracket is molded. An object of the present invention is to provide a door inner seal mounting structure that is simple and inexpensive, and that has sufficient mounting strength to withstand the external force applied downwardly to the door inner seal.

[Means for Solving the Problems]

 In order to achieve the above object, the present invention secures a resin bracket, which is an elongated body having a substantially L-shaped cross section, to the back surface of the upper edge of the door trim, and attaches it to the inner seal mounting surface of the resin bracket. Installing the door inner seal In the door inner seal mounting structure, notches are opened at appropriate intervals at the lower edge of the inner bracket mounting surface of the resin bracket, and support flanges are formed in a row. The locking claw of the inner seal is bent after being inserted into the notch, and the lower edge of the door inner seal is held by a support flange.

[0008]

[Action]

 As is clear from the above configuration, the locking structure of the locking claw of the door inner seal is configured to be inserted into the notch provided in the lower edge instead of the conventional mounting hole formed in the resin bracket. The resin bracket does not have an undercut shape and can be molded with a simple and inexpensive mold structure that does not require a slide core and has a stationary mold and a movable mold.

Further, since the door inner seal is supported by the support flange continuously provided on the lower edge of the resin bracket, the door inner seal does not graze even when an external force in the downward direction is applied. , The door inner seal can be firmly held by the resin bracket.

[0010]

【Example】

 Hereinafter, an embodiment of a door inner seal mounting structure according to the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is an overall perspective view showing a mounting structure of a door inner seal according to the present invention, and FIG. 2 is a sectional view showing the mounting structure of the door inner seal.

In FIG. 1, an automobile door trim 10 is constructed by adhering a skin material 12 to the surface of a core material 11 formed in a required shape, and is made of a long body having a substantially L-shaped cross section. A door inner seal 30 that is in sliding contact with the door window glass is attached via a resin bracket 20 that is made of resin.

More specifically, the resin bracket 20 is made by injection molding a general-purpose synthetic resin such as ABS resin, and has a trim mounting portion 21 having a shape matching the shape of the back surface of the core material 11 of the door trim 10, and a door inner seal. In this embodiment, the trim mounting portion 21 of the resin bracket 20 is welded and fixed to the back surface of the core material 11 of the door trim 10 by ultrasonic welding.

Further, as shown in the figure, the inner seal mounting surface 22 of the resin bracket 20 has a notch 23 and a horizontally extending support flange 24 along the lower edge 22a at predetermined intervals. They are formed alternately.

On the other hand, the door inner seal 30 having the conventional structure is used. To briefly explain the structure, the door inner seal body 32 having the lip portion 31 at the upper end is formed by extrusion molding of soft vinyl chloride resin or the like. A core metal 33 made of a thin metal plate is inserted inside the door inner seal body 32, and two seal tongue pieces 34 are provided on one surface (door window glass side) of the door inner seal body 32 with the body 32. In addition to being integrally formed, locking claws 35 are cut and raised from the core metal 33 at predetermined intervals so as to correspond to the notches 23 of the resin bracket 20 on the opposite side.

Therefore, after the trim mounting portion 21 of the resin bracket 20 is fixed to the back surface of the core material 11 of the door trim 10, the door inner seal 30 is attached to the support flange 24 with respect to the inner seal mounting surface 22 of the resin bracket 20. After the door inner seal 30 is positioned so as to be placed, the locking claws 35 of the door inner seal 30 are inserted into the notches 23, and then the door inner seal 30 shown in FIG.

As described above, according to the present invention, the resin bracket 20 serving as a medium for attaching the door inner seal 30 to the door trim 10 has a notch 23 along the lower edge 22 a of the inner seal mounting surface 22. Since the support flange 24 and the support flange 24 are formed alternately, the resin bracket 20 does not have an undercut shape, and can be formed only by the fixed side mold and the movable side mold, and the conventional slide type is used. Since the complicated mold structure such as the core is not required, the resin bracket 20 can be provided easily and inexpensively.

Further, as shown in FIG. 2, when the door inner seal 30 is attached to the door trim 10 via the resin bracket 20, the door inner seal 30 is held by the plurality of support flanges 24. For example, when the elevating door window glass 30 is moved up and down, particularly when the window glass 30 is lowered, downward stress is applied to the door inner seal 30, but the support flange 24 holds the door inner seal 30. It is possible to effectively solve the conventional problems such as the mounting strength being lowered due to the downward grabbing of 30 and the deformation of the locking claw 35, and a smooth lifting operation of the lifting door window glass can be expected for a long period of time. .

In this embodiment, the resin bracket 20 is fixed to the back surface of the core material 11 of the door trim 10 by ultrasonic welding. However, a conventional fixing means such as an adhesive stopper or a rivet stopper may be applied. Absent.

Further, the support flanges 24 that are horizontally formed continuously on the lower edge 22a of the inner seal mounting surface 22 of the resin bracket 20 are formed alternately with the notches 23, but the support flanges 24 are not necessarily alternate. It does not need to be formed, and can be partially abolished.

[0021]

[Effect of device]

 As described above, the mounting structure of the door inner seal according to the present invention has the following special operational effects.

(1) When attaching the door inner seal to the door trim via the resin bracket, the conventional mounting hole is eliminated from the resin bracket, and the resin bracket is fixed along the lower edge of the inner seal mounting surface of the resin bracket. Since the notch and the horizontally extending support flange are formed at every interval, the resin bracket does not have an undercut shape, the conventional slide core can be eliminated, and the molding die equipment can be simplified. This has the effect of significantly reducing the processing cost of the resin bracket and contributing greatly to the reduction of the product cost.

(2) Since a support flange is provided on the lower edge of the inner seal mounting surface of the resin bracket, and the lower edge of the door inner seal is supported by this support flange, the lifting door window glass is particularly useful. Even when a large downward force is applied to the door inner seal during the lowering operation of the door, it is firmly supported by the support flange, so the door window glass will not be scratched and the locking claws will be deformed. As a result, it is possible to effectively solve the conventional problems such as a reduction in mounting strength, and to firmly and securely mount the door inner seal.
