Abstract

PURPOSE:To ensure the easy mounting of a seal material to a defroster nozzle outlet by forming an externally directed flange-like bonding surface at the end of each outlet, attaching the seal material having a double-sided adhesive tape thereto and inserting a garnish into the seal material via a cylindrical garnish insertion hole formed therein for bonding the seal material to the outlet. CONSTITUTION:An externally directed flange-like bonding surface 11 is formed around the end of each outlet 10 of a defroster nozzle body 5, and a sheet-like seal material 20 of urethane foam is attached thereto with a double-sided adhesive tape 19 in such a way as to cover the outlet 10. In this case, a part of the tape 19 not faced to the aforesaid surface 11 covers the opening of the outlet 10, together with the seal material 20. Furthermore, an insertion hole 21 for a garnish 9 is so formed in the seal material 20 as to be rather small, and the garnish 9 is inserted therein. As a result, the seal material 20 projected into the outlet 10 is bent inward and bonded to the inner surface thereof. According to the aforesaid construction, the seal material 20 can be so mounted as to ensure a high sealing effect.

Detailed Description of the Invention (Industrial Application Field) The present invention relates to the inner periphery of a plurality of air outlets protruding upward from a defroster nozzle body, and the cylindrical shape of the upper surface of an instrument panel inserted into the inner periphery. The present invention relates to a sealing structure and method for a defroster nozzle outlet to ensure sealing performance between garnishes.

(Prior Art) A plurality of finned cylindrical garnishes 9 are attached to the upper surface 1a of the instrument panel 1 in the vehicle direction in FIG. It has been inserted.

At that time, as shown in FIG. 6, in order to seal the outlet 5a, the outer periphery of the cylindrical garnish 9 or the outlet 5a is prepared in advance.
A sealing material 6 was adhered to the inner circumference of a.

[Invention or problem to be solved]

Because of this, sealing work is required for each outlet,
In some cases, sealing failures occurred due to the mutual positional relationship.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a sealing structure and method for a defroster nozzle outlet that is easy to assemble and can improve sealing performance.

[Means to solve the problem]

The present invention has a seal structure to achieve this purpose, in which an outward flange-like adhesive surface is formed at the tip of each outlet, and a common adhesive surface for each outlet is attached to one side of double-sided adhesive tape on the back side. The sealant is adhered to the adhesive surface and the side surface of the outlet with the opposite side of the double-sided adhesive tape, with each cylindrical garnish inserted into its associated outlet through each insertion opening formed by cutting out the sealant. It is characterized by the presence of

In addition, as a sealing method to achieve the object of the present invention, an outward-facing flange-like adhesive surface is formed at the tip of each outlet, and one side of double-sided adhesive tape is attached to the back side of a sealing material common to each outlet. At the same time, cut out the part facing each outlet as a small garnish insertion hole on the inside, and apply sealant to the opposite side of the double-sided adhesive tape to the garnish insertion hole or the corresponding part of each outlet. Glue each cylindrical garnish so that it occupies the same position, and insert each cylindrical garnish from its garnish insertion port into its associated outlet, and then turn the sealing material that was floating inside the adhesive surface to the opposite side and place it on the side of the outlet. Glue.

(Function) By being bonded on the adhesive surface, the sealing material is interposed on the back side of the instrument panel at each air outlet, and further extends continuously to the side of the air outlet, reliably closing the gap at the upper end of the air outlet. It also provides a cushioning effect on the instrument panel and the air outlet opening.

According to the sealing method of the present invention, in the process of inserting the cylindrical garnish from the garnish insertion port into the associated outlet,
The sealing material that was floating inside the adhesive surface is automatically adhered to the side of the outlet.

〔Example〕

1 to 3 show a defroster structure for carrying out a sealing method according to an embodiment of the present invention, and FIGS.
The same reference numerals as those in the figures indicate the same or equivalent parts.

In FIGS. 1 and 2, an outwardly facing flange-shaped adhesive surface 11 is formed around the tip of each of the plurality of air outlets 10 that are provided upwardly projecting from the defroster nozzle main body 5. In addition, a sheet-like sealing material 20 made of, for example, foamed urethane is prepared to cover the adhesive surface 11 of each outlet 10, and a double-sided adhesive tape 19 is adhered to the back surface, and a sheet-like sealing material 20 is prepared to cover the adhesive surface 11 of each outlet 10. A smaller portion is punched out as a garnish insertion opening 21 toward the inside, and a cut 22 is formed in the raised portion 4w4 toward the inside.

During assembly, one side of the double-sided adhesive tape 19 is adhered to the back side in this way, and the sealing material 20 is attached to the back side.
The opposite side of the double-sided adhesive tape 19 is adhered to the adhesive surface 11 so that the garnish insertion opening 21 is located at a predetermined inner side of each outlet 10 (FIG. 3A). Next, the finned cylindrical garnish 9 attached to the instrument panel pad ib on the upper surface of the instrument panel l is inserted into the associated air outlet lO through the garnish insertion port 21. At that time, gradually bend the floating part 11a of the sealing material on the inside downward, and then
is seated on the adhesive surface 11 with a
). Thereby, even if there is a gap around the sealing material portion 11a, the sealing material 20 of the adhesive surface 11 or the tip circumferential surface of the outlet lO and the outer circumferential surface of the cylindrical garnish 9 are reliably sealed.

〔Effect of the invention〕

As described above, according to the seal structure of the present invention, the sealing material is interposed between the tip of the air outlet and the back surface of the instrument panel and extends continuously to the side surface of the air outlet, thereby making the sealing function more reliable. The presence of wood improves the quality of building materials and suppresses abnormal noises.

Further, the sealing method of the present invention not only improves the sealing function and the construction material, but also allows a common sealing material or garnish to be assembled into a plurality of outlets at the same time during the insertion process, making the work extremely efficient.
