Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an improvement in an inner seal for a door trim, which is attached to an automobile door trim and is in sliding contact with a door window glass.

[0002]

[Prior Art]

 Normally, an automobile door trim is equipped with an inner seal for a door trim that is in sliding contact with a lifting window glass.

FIG. 3 shows a conventional door trim having an inner seal for a door trim attached thereto. In the figure, a door trim 1 is attached to a surface of a core material 2 formed into a required shape. The door trim 1 is provided with a waist flange portion 5 which extends downward in order to attach the inner seal 4 for the door trim, and the inner seal 4 is attached to the waist flange portion 5. It is designed to be attached via a metal stitcher or other attachment.

Further, in another conventional example, in forming the door trim 1, the waist flange portion 5 has an undercut shape, which requires a large-scale molding facility and prevents material restrictions. As shown in FIG. 4, a metal bracket 6 may be fixed to the back surface of the core material 2, and the inner seal 4 may be attached to the bracket 6 via the skin material 3.

[0005]

[Problems to be solved by the device]

 As described above, the conventional door trim inner seal 4 is configured to be fixed to the waist flange portion 5 or the bracket 6, but the skin material 3 is provided between the inner seal 4 and the waist flange portion 5 (bracket 6). However, the elasticity of the skin material 3 causes the inner seal 4 to be slack when the door window glass is moved up and down, making it difficult to expect a smooth door window movement. ..

Furthermore, since the inner seal 4 is attached to the door trim 1 instead of the door inner panel 7, the attachment position of the inner seal 4 depends on the door trim 1 due to an attachment error of the door trim 1, a dimensional error, etc. However, this is also a factor that hinders the operation of raising and lowering the door window glass.

In addition, in the mounting structure of the inner seal 4 shown in FIG. 3, since the waist flange portion 5 is undercut when the core material 2 is molded in the door trim 1, the molding facility becomes large. In addition, there is a problem in that a material having excellent moldability must be used, and the material used is greatly restricted. In addition, when the bracket 6 shown in FIG. 4 is used, a different bracket 6 is used. Since it is necessary, there is a problem that the cost increases due to the increase in the number of parts.

The present invention has been made in view of such circumstances, and an object of the present invention is to enable an inner seal for a door trim to be securely and firmly attached to an appropriate position, and moreover, a waist flange. Since it does not require a part, it is to provide an inner seal for a door trim that can be manufactured at low cost.

[0009]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention comprises an elastic strip having a seal tongue that is in sliding contact with a door window glass, and a core bar that holds the upper and lower edges of the elastic strip. In the inner trim for door trim, a curl portion for sandwiching the front end portion of the door trim is provided at the upper end portion of the core metal, and a locking piece cut and raised on the core metal secures it to the door inner panel. It is characterized by doing.

[0010]

[Effect] As is apparent from the above structure, the core metal holding the upper and lower edges of the elastic strip is fixed to the door inner panel through the locking piece, so that the door trim (soft It becomes possible to attach the inner seal for the door trim more reliably and firmly than the configuration in which the inner seal is attached via the skin material).

Further, since the curl portion formed at the upper end portion of the core bar clamps the front end portion of the door trim, it is not necessary to form a waist flange portion on the door trim, and a separate bracket is required. Never.

【Example】

 Hereinafter, embodiments of an inner seal for a door trim according to the present invention will be described in detail with reference to the accompanying drawings.

1 and 2 show an embodiment of the present invention. FIG. 1 is an exploded perspective view showing a door trim, a door panel, and an inner seal for a door trim, and FIG. 2 is a door inner panel and a door trim. It is sectional drawing which shows the state which attached the inner seal for door trims.

In FIG. 1, an inner seal 10 for a door trim in this embodiment has an elastic strip 20 made of synthetic rubber, soft vinyl chloride or the like, and a shape-retaining property for holding upper and lower edges of the elastic strip 20. It is composed of a metal cored bar 30.

More specifically, the elastic strip 20 is formed with two sealing tongues 21 integrally therewith, and the sealing tongues 21 have a sealing function by slidingly contacting a door window glass (not shown). ..

On the other hand, the cored bar 30 is provided with holding portions 31 and 32 for holding the upper and lower edge portions of the elastic strip 20, and is further connected to the upper holding portion 31 to bend the curl portion 33. In addition, locking pieces 34 having an L-shaped cross section are cut and raised at appropriate intervals in the longitudinal direction, and further, locking claws 35 and 36 are cut and raised in opposite directions. There is.

Reference numeral 40 in the figure denotes an automobile door trim, which has a laminated structure in which a surface of a core material 41 having shape retention property is covered with a skin material 43 via a pad material 42.

Reference numeral 50 in the figure denotes a door inner panel.

Next, the mounting structure of the inner seal 10 according to the present invention will be described with reference to FIG. 2. First, the engagement piece 34 provided on the inner panel 10 is engaged with the flange portion 51 of the door inner panel 50. The flanges 51 of the door inner panel 50 are held by the locking claws 35 and 36.

After that, the door trim 40 is attached to the door inner panel 50 via an attachment such as a clip (not shown), and the tip portion 40 a of the door trim 40 is press-fitted into the curl portion 33 formed in the core metal 30 of the inner seal 10. If so, the inner seal 10 and the door trim 40 can be easily and surely attached to the door inner panel 50.

As a mounting order, after the door trim 40 is mounted on the door inner panel 50, the inner seal 10 may be mounted on the flange portion 51 of the door inner panel 50 and the door trim 40.

As described above, since the door trim inner seal 10 according to the present invention is directly attached to the door inner panel 50 by the locking piece 34 provided on the core metal 30, the inner seal 10 is attached to the door trim as compared with the conventional one. It has excellent strength and has the advantage that you can expect smooth door window glass up-and-down operation without causing grinds during door window glass up-and-down operations.

Further, since the door trim inner seal 10 can always be positioned at a proper position without being influenced by the mounting error and the dimensional error of the door trim 40, this also facilitates the smooth operation of raising and lowering the door window glass. You will be guaranteed.

In addition, since it is not necessary to form a waist flange portion in the door trim 40 as in the conventional case and a separate bracket is not necessary, large-scale molding equipment is not required and the material used is also not required. It is possible to use materials that are relatively inferior in formability, and in consideration of the reduction in the number of parts, etc., it is extremely useful in practice.
