Description

[Detailed Description of the Invention] <<Industrial Application Field>> The present invention relates to a heater duct for an automobile, and particularly to a mounting structure for a heater duct disposed between a floor panel and a floor carpet.

《Prior art》 As shown in Fig. 4, an automobile heater duct has an approximately Y connecting the front side F and the rear side R.
A letter-shaped heater duct is disposed in the tunnel portion 2a of the floor panel 2, and the heater duct 1 is hidden by a floor carpet 4 having an under material 4b provided on the lower surface of the pile layer 4a as shown in FIG. There is a system that blows hot air to the passenger seated on the rear side R without exposing it to the interior of the vehicle.

<<Problems to be Solved by the Invention>> Incidentally, this type of heater duct 1 is formed relatively flat so as to follow the shape of the floor, but when placed on the floor panel 2, it inevitably protrudes from the floor panel 2. For this reason, if the floor carpet 4 is laid with the heater duct 1 placed on the floor panel 2, the heater duct 1 may become uneven, or gaps may easily form at the corners of the heater duct 1, so the floor carpet may simply be laid. Even if covered with carpet, the fit with the floor carpet 4 is extremely poor.

Further, as a method of fixing the heater duct 1, for example, as shown in FIG.
b is often used to fix the locking portion so that it does not protrude. However, when fixing to the partition portion 2b or the like in this manner, not only does the structure become complicated, but also the fixing locations are limited, so there is also the problem that rattling and positional displacement are likely to occur.

The present invention was devised in view of the above circumstances, and aims to provide a carpet that can be firmly fixed without wobbling or shifting, and to improve the fit with the floor carpet.

<Means for solving the problem> That is, the mounting structure of the automotive heater duct of the present invention divides the heater duct into two parts, an upper side and a lower side, fixes the lower side to the floor panel, and It is characterized in that the upper side is fixed to the lower surface of the floor carpet and engaged with the lower side.

<Operation> Since the heater duct is arranged fixed to the floor panel and the floor carpet, there is no risk of the heater duct shifting from the floor carpet, and the fit with the floor carpet is also improved. .

<<Example>> Hereinafter, an example of the present invention will be described with reference to the drawings. FIG. 1 is a divided sectional view showing a heater duct mounting structure to which the present invention is applied, and FIG. 2 is a partial sectional view showing the completed state of mounting the heater duct. In these figures, the automobile heater duct 10 is divided into two parts, an upper side 11 and a lower side 12, and by appropriately engaging the two, the heater duct 10 is divided into two parts, and is connected between a floor panel 20 and a floor carpet 30 as in the conventional case. The structure is such that hot air is sent from the front side to the rear side.

Upper side 11 constituting the heater duct 10
The lower side 12 is formed into a desired shape by a heat-resistant resin material, a metal material, etc., and a protrusion 12a provided on the upper edge of the lower side 12 engages a claw 11a provided on the lower edge of the upper side 11. They are each formed so that they can be easily combined by fitting them together.

The lower side 12 is arranged near both sides of the tunnel portion 20a in the floor panel 20, and is fixed to the floor panel 20 with screws 40. Further, the upper side 11 is located on the back side of the floor carpet 30 in which an under material 30b such as chip urethane is provided on the underside of the pile layer 30a.
It is fixed at the position corresponding to 2. This fixing means may be achieved by using an adhesive 50 as in this embodiment, or by welding. Alternatively, the upper side 11 may be joined when the floor carpet 30 is molded.

The floor carpet 30 with the upper side 11 fixed in this way is, for example, a floor panel 2, as in the conventional case.
The floor panel 20 is fixed at an appropriate position with clips or both sides, and laid so as to cover the floor panel 20. In this case, as shown in FIG.
1 and the lower side 12 are engaged to form an integral heater duct 10. Furthermore, since the integrally engaged heater duct 10 is fixed to the floor carpet 30 and the floor panel 20, respectively, not only the problems of the conventional heater duct 10 are eliminated, but also the heater duct 10 can be used as a fixing means for the floor carpet 30 itself. will also function.

Note that FIG. 3 shows a modification of the engagement structure between the upper side 11 and the lower side 12. That is, in this modification, the recess 11b is provided at the lower edge of the upper side 11.
This is an example in which a convex portion 12b corresponding to the concave portion 11b is provided on the lower side 12, and the convex portion 12b is fitted into the concave portion 11b, which is a so-called clip-fastening structure. It goes without saying that the engagement structure can be modified in various ways as described above.

<<Effect of the invention>> As explained above, according to the invention, the divided heater duct is fixed to the floor panel and the floor carpet, respectively, and is engaged as an integrated heater duct, so that the floor carpet This improves the fit with the floor panel, and it can be firmly fixed without being restricted by the fixing location on the floor panel side.

Furthermore, according to the mounting structure of the present invention, the floor carpet is reliably fixed to the floor panel via the two-divided heater duct, so it functions effectively as one of the means for fixing the floor carpet itself. It also has this effect.
