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. 3, an automobile heater duct has an approximately Y-type structure that connects the front side F and the rear side R.
A letter-shaped heater duct 1 is disposed in a tunnel portion 2a of a floor panel 2, and the heater duct 1 is hidden by a floor carpet 4 provided with an under material 4b on the lower surface of a pile layer 4a as shown in FIG. There is a system in which hot air is sent to the passenger seated on the rear side R without being exposed 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 Problems> In other words, the automotive heater duct mounting structure of the present invention provides a groove in the floor panel into which the heater duct can fit, and the heater duct is positioned at a position corresponding to the groove. It is characterized in that it is fixed to the lower surface of the under material of the floor carpet, and the fixed heater duct is fitted into the groove.

<<Operation>> Since the heater duct is fixed to the floor carpet, it does not shift from the floor carpet, and the fit with the floor carpet is also improved.

An embodiment of the present invention will now be described with reference to Figs. 1 and 2.

FIG. 1 is a longitudinal sectional view showing a floor panel of an automobile to which the present invention is applied. In the figure, a floor panel 10 of an automobile has a heater duct 20 on the rear side that connects the front side and the rear side as in the conventional case.
They are arranged so as to branch out into two branches with each side in between, and are concealed by the floor carpet 30, and hot air can be sent from the front side to the rear side.

The floor carpet 30 has a pile layer 30a
It is lined with a polyethylene sheet to prevent the pile from falling out, and also improves durability and stepping comfort.
Urethane foam to obtain properties such as sound insulation,
Under material 30b such as chip urethane is approximately 10~
It is provided with a thickness of 30mm. The heater duct 20 is attached to the lower surface of the under material 30b, and when the floor carpet 30 is laid on the floor panel 10, the heater duct 2
0 is arranged at a fixed position.

In other words, the heater duct 20
As shown in the figure, it is made of a blow-molded body or the like, and a pair of flanges 21 are integrally provided on an upper surface 20a to protrude in the length direction. Also, this heater duct 20
A groove portion 31 corresponding to the heater duct 20 is formed in the under material 30b to which the flange portion 21 is attached.
By biting into the heater duct 20, the heater duct 20 is fixed.

The floor carpet 30 with the heater duct 20 fixed thereto is fixed, for example, with clips or double-sided tape at appropriate positions on the floor panel 10, and is laid to cover the floor panel 10, as in the conventional case. In this case, as shown in FIG. 1, a locking groove 11 corresponding to the heater duct 20 is provided in the floor panel 10, and the lower part of the heater duct 20 fixed to the floor carpet 30 is fitted into the locking groove 11. This prevents the floor carpet 30 from protruding due to the heater duct 20, and can effectively function as one of the fixing means for the floor carpet 30 itself.

In addition, the under material 30 of the floor carpet 30
The method of fixing the heater duct 20 to b is not limited to this embodiment, and it is of course possible to fix the heater duct 20 directly to the under material 30b by adhesive or welding, for example, without providing the groove 31 in the under material 30b. It is.

As explained above, according to this device, the heater duct is fixed to the floor carpet beforehand and is arranged on the floor panel, so it fits well with the floor carpet and can be fixed firmly without being restricted by the fixing point. Moreover, by forming a groove in the under material of the floor carpet and inserting the heater duct into this groove to fix it, it is possible to prevent the heater duct from protruding as in the past, and therefore to make the interior space of the vehicle larger.
