Description

DETAILED DESCRIPTION OF THE INVENTION << Industrial Application Field >> The present invention relates to an improvement in a weatherstrip mounting structure in an automobile door trim.

<< Prior Art >> Usually, a weather strip is attached to a bent flange portion of an upper edge portion of a door trim in a vehicle door trim installed in a door panel in order to provide a sealing function to a lifting window glass.

By the way, as a recent tendency, the upper edge of the front part of the door trim and the upper edge of the instrument panel are made to coincide with each other in terms of shaping in the vehicle interior, and a sense of unity between the interior parts is revealed to improve interior aesthetics. I am trying.

Therefore, in FIG. 7, an automobile door trim 1 is composed of a resin core material 2 formed in a required shape and a skin material 3 having a decorative property and cushioning property, which is attached to the surface of the resin core material 2. The upper end edge is bent downward, and the bent flange portion 5 for mounting the weather strip 4 is provided. As described above, the vertical dimension of the bent flange portion at the front end portion is shown in FIG. It is set to the code l ₁ , and the vertical dimension is gradually changed toward the center side, and finally dropped to the code l ₂ . Therefore, since the vertical dimension of the weather strip 4 is constant, the shape of the door trim 1 is an inclined portion shown by the hatched portion in FIG.

Usually, as a molding method of the core material 2 of the door trim 1 for an automobile, it is often used to mold press mold a thermoplastic resin material in a molten state because of its good moldability. In order to obtain the door trim 1 having the shape shown in the figure, the resin core material 2 and the skin material 3 are molded in the mold press dies 6 and 7 as shown in FIG. In order to mold the area shown by the shaded area,
The portion indicated by reference numeral 8 in FIG. 8 must be set so as to have a tapered shape, and molding is impossible due to the shape structure.

<Problems to be solved by the invention> Therefore, the door trim 1 cannot be molded by the mold press method with good moldability, and it is necessary to take measures such as setting a separate spacer, which is a major factor of cost increase. Was there.

Further, in the conventional structure for mounting the weather strip 4, the lip portion of the weather strip 4 covers the upper end portion of the door trim 1 in the general portion, but as shown in FIG. At the same time, it has been pointed out that there is a problem that it raises and deteriorates the aesthetics,
In addition, there is a problem in that the shape of the door inner panel is restricted because the front end portion of the door trim 1 has a step portion 1a.

The present invention has been made in view of such circumstances, and an object of the present invention is to manufacture a bent flange portion of a door trim for attaching a weather strip with a simple press die structure, which results in a manufacturing cost. It is possible to significantly reduce the cost, and to prevent the deterioration of the aesthetic appearance due to the floating of the upper lip of the weather strip as much as possible to reduce the cost and improve the aesthetic appearance. To provide.

<Means for Solving the Problems> In order to achieve the above object, the present invention provides a weather with a sealing tongue slidably contacting a window glass on a bent flange portion formed at an upper edge of an automobile door trim. In a weatherstrip mounting structure in which a strip is mounted, a protrusion for hiding the upper edge lip of the weatherstrip is provided at the upper edge of the door trim bent flange portion, and the vertical dimension of this protrusion is set larger as it goes forward. The upper and lower dimensions of the protrusion are gradually changed so that the upper edges on both sides of the instrument panel, which is installed under the front window and bulges toward the passenger compartment, almost coincides with the upper edge on the front end side of the door trim. It is characterized by that.

<Operation> As is apparent from the above configuration, according to the weatherstrip mounting structure of the present invention, the bent flange portion of the door trim to which the weatherstrip is mounted has the protrusion that hides the upper lip portion of the weatherstrip in the longitudinal direction thereof. The upper edge lip portion of the weather strip, which has conventionally been unsatisfactory in appearance, can be covered with the door trim.

Further, in order to match the upper end portions of the door trim and the instrument panel, the vertical dimension of the bent flange portion of the door trim can be changed, and the vertical dimension of the protrusion can be gradually changed. It will be possible to deal with it only.

<< Example >> Hereinafter, a weather strip 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 weatherstrip mounting structure according to the present invention, and FIGS. 2 and 3 are sectional views showing a state in which the weatherstrip is mounted on a door trim side.
FIG. 5 is an explanatory view showing a state when a door trim for attaching a weather strip is formed, and FIGS. 5 and 6 show another embodiment of the present invention, which are sectional views showing a state where the weather strip is attached to the door trim side. Is.

First, a first embodiment of the present invention will be described with reference to FIGS.

Referring to FIG. 1, an automobile door trim 10 used in this embodiment is generally composed of a resin core material 11 formed in a required shape and a skin material integrally attached to the surface side of the resin core material 11. As the resin core material 11, polypropylene resin is preferable in consideration of moldability, cost, strength, etc., and polypropylene resin in a molten state is supplied into a mold for mold press molding to perform mold press molding. As a result, it is molded into the required shape. Further, as the skin material 12, since it is preferable to have surface decoration and cushioning properties, a foamed vinyl chloride sheet is used in this example, and is molded and press-molded integrally with the resin core material 11. .

And, the upper end portion of the door trim 10 is a bent flange portion bent downward for attaching a weather strip.
13 is provided, and a projecting portion 14 is provided in an upper portion of the bent flange portion 13 along the longitudinal direction of the door trim 10.

On the other hand, the weather strip 15 attached to the bent flange portion 13 of the door trim 10 covers the outer periphery of a metal core material 16 made of a flat metal plate with an elastic body 17 such as rubber or soft vinyl chloride, and is not shown on one side surface. A seal tongue 18 slidably contacting the window glass is provided, and on the other side surface,
Locking claws 19 in which the metal core material 16 is cut and raised are provided at appropriate intervals, and the locking claws 19 are bent and fixed to the mounting holes 20 formed in the bending flange portion 13, and the weather strip 15 is provided. Will be attached to the bent flange portion 13 of the door trim 10.

The feature of the present invention is the shape of the protrusion 14 that is set on the upper portion of the bent flange portion 13.

That is, the upper end lip portion 15a of the weather strip 15 is covered by the protrusion 14, and the upper end lip portion 15a of the weather strip 15 is hidden from the vehicle interior side.
Conventionally, the protrusion 14 can effectively solve the problem that the lip portion 15a floats and the aesthetic appearance is deteriorated.

Furthermore, the protrusion 14 is formed at the front end portion of the door trim 10.
The vertical dimension is set to be large, and the vertical dimension is set to be gradually reduced toward the center. Due to the molding of the door trim 10, this is set so that the upper end portions of the instrument panel (not shown) and the front end portion of the door trim 10 are aligned with each other, so that the interior parts have a sense of unity. This is to improve the aesthetics of the room.

Due to such a structure, for example, the state of the door trim 10 at the time of molding will be described with reference to FIG. 4, in which the resin core material 11 is composed of the lower mold 30 for mold press and the upper mold 31 for mold press.
In addition, the skin material 12 is integrally molded and press-molded, but in order to mold the bent flange portion 13 of the door trim 10 into a required shape, the core 32 is set in the lower mold 30 for molding press. In the child 32, the portion indicated by the reference numeral 33 corresponds to the hatched portion in FIG. 1, and the bending flange portion 13 and the protruding portion of the door trim 10 as well as the protruding portion can be formed only by setting the inclined portion 33 in the core 32. 14 can be easily molded.

Therefore, there is an advantage that molding can be performed only by devising the mold shape of the mold for a mold press, and the door trim 10 can be molded by a low-priced mold press mold device, which can expect a significant cost reduction.

Next, FIGS. 5 and 6 show another embodiment of the present invention. First, the embodiment shown in FIG.
A metal bracket 40 having a substantially L-shaped cross section is integrally formed at the time of molding the resin core material 11, and a bent flange portion 41 for mounting the weather strip 15 is constituted by the metal bracket, and above the bent flange portion 41. The protrusion 42 is formed on the ridge, and the dimension of the protrusion 42 is gradually changed so that the fitting portion of the door trim 10 and the instrument panel is integrated, and the lip portion 15a of the weather strip 15 is formed by the protrusion 42. It has the same function and effect as those of the first embodiment for covering and improving the aesthetic appearance.

Next, the one shown in FIG. 6 is a bent flange portion in which a bent substantially L-shaped metal bracket 43 is fixed to the back side of the resin core material 11, and the weather strip 15 is attached by the metal bracket 43. The construction of 44 is similar to that of FIG. 5, but the upper end lip portion 15a of this weather strip 15 is
The protrusion 45 that covers the door trim 10 is formed by the front end portion of the door trim 10.

<< Advantages of the Invention >> As is clear from the above description, the weather strip mounting structure in the vehicle door trim according to the present invention has the following special operational effects.

According to the attachment structure of the weather strip according to the present invention, the protrusion that covers the upper lip portion of the weather strip is set along the longitudinal direction of the door trim, and the vertical dimension of this protrusion is set at the front end portion of the door trim. Since it is large and the vertical dimension is gradually changed toward the center, it is possible to mold the bent flange portion of the door trim with a simple mold press die, and it is possible to expect a significant cost reduction.

According to the present invention, the upper end lip portion of the weather strip is covered by the protrusion formed along the longitudinal direction, so that the upper end lip portion of the weather strip floats up as in the prior art, and the appearance is deteriorated. This has the effect of effectively solving defects and improving the aesthetics of the room.

According to the present invention, a protrusion that bulges toward the passenger compartment is provided in the upper portion of the bent flange portion of the door trim to which the weather strip is attached, and a step portion that bends toward the door inner panel side as in the conventional case is provided. Since it cannot be formed, the conventional problem that the shape of the door inner panel is restricted can be effectively solved, and there is an advantage that restrictions on modeling of the door inner panel can be relaxed.
