Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a rear heater duct blowing structure for blowing warm air toward a rear seat in a vehicle such as a passenger car.
[0002]
[Prior art]
Conventionally, particularly in a cold district vehicle, as shown in FIG. 3, for example, a rear heater duct 3 is arranged on the floor panel 2 below the front seat 1 (seat cushion 1a), and hot air is blown to the rear seat side. Like to do. In this case, one end (front end) of the rear heater duct 3 is connected to the heater unit 4, and the other end (rear end) is opened near the lower rear portion of the seat cushion 1a.
[0003]
In FIG. 3, a rear seat raising member 5 is disposed on the floor panel 2 of the rear seat, and a carpet 6 is laid thereon. A cross member 7 is disposed on the floor panel 2 below the seat cushion 1a, and a floor silencer (asphalt seat) 8 is laid in a region between the cross member 7 and the rear seat raising member 5.
[0004]
The warm air supplied from the heater unit 4 to the front end opening of the rear heater duct 3 passes through the rear heater duct 3 from the rear end opening of the rear heater duct 3 and is placed on the carpet 6 as shown in the figure. The air is blown around 100.
[0005]
[Problems to be solved by the invention]
As described above, in the conventional rear heater duct blower structure, the dedicated rear heater duct 3 is provided particularly at the lower portion of the front seat 1 in order to secure the blower passage.
Therefore, the floor surface is uneven, and the lower portion of the front seat 1 is substantially a dead space. In addition, the number of parts has increased, such as the provision of a floor silencer 8.
[0006]
In view of the above circumstances, an object of the present invention is to provide a rear heater duct blower structure for an automobile capable of effectively utilizing a space with a relatively simple configuration.
[0007]
[Means for Solving the Problems]
The rear heater duct blower structure for an automobile of the present invention is a rear heater duct blower structure for an automobile that is set at the lower part of the front seat in order to blow the warm air from the heater unit to the rear seat side. The front seat under-lifting material disposed in the rear seat and the rear seat under-lifting material disposed at the foot of the rear seat, the front seat under-lifting material has a flat upper surface and a recess formed on the lower surface. The rear seat raising material extends to the front seat lower raising material, and the air passage is formed by the recess of the front seat lower raising material and the rear seat raising material.
[0009]
Further, in the rear heater duct air blowing structure for an automobile according to the present invention, a heater duct connected to the heater unit is connected to the front opening of the air blowing passage so as to blow warm air from the rear opening of the air blowing passage to the rear seat side. It is characterized by that.
[0010]
Furthermore, in the rear heater duct blower structure for an automobile according to the present invention, the front seat is configured as a passenger seat, and the passenger seat is tumble-supported on the raising material under the front seat disposed under the front seat. It is characterized by being.
[0011]
According to the present invention, the air passage is formed with the rear seat raising material only by adding the front seat lowering material disposed at the lower portion of the front seat, and the configuration is substantially simplified. In this case, the space around the lower portion of the front seat can be effectively utilized by supporting the front seat on the raising material under the front seat so as to be tumbleable.
[0012]
DETAILED DESCRIPTION OF THE INVENTION
A preferred embodiment of a rear heater duct blower structure for an automobile according to the present invention will be described below with reference to the drawings.
FIG. 1 shows a rear heater duct blower structure in an embodiment of the present invention. In this embodiment, in a cold district vehicle, the present invention is applied particularly to a passenger seat, and warm air is blown to the rear seat side.
[0013]
On the floor panel 2, a cross member 7 is arranged in the vehicle left-right direction in the front seat 1, in this example, in the front part of the lower part of the front seat 1 on the passenger seat side, and the rear heater duct 3 ′ The cross member 7 arranged on the top is provided. The front end of the rear heater duct 3 ′ is connected to the heater unit 4, and the other end side, that is, the rear end is connected to an air passage described later.
In FIG. 1, a rear seat raising member 5 ′ is disposed at a predetermined height on the floor panel 2 of the rear seat, and a carpet 6 is laid thereon. A cross member 7 is disposed on the floor panel 2 below the seat cushion 1a of the front seat.
[0014]
In the present invention, the front seat lower raising member 10 is disposed at the lower part of the front seat 1, and the air passage 11 is formed between the rear seat raising member 5 '. In this case, the rear seat raising member 5 ′ is extended to the front seat lower raising member 10 with the extension portion 12, and between the front seat lower raising member 10 and the extension portion 12 of the rear seat raising member 5 ′. By forming the air gap, the air passage 11 is formed on the lower surface of the front sheet lowering material 10. In the present embodiment, as shown in FIG. 2, the air passage 11 is recessed by forming a recess 10 a in the vehicle front-rear direction on the lower surface of the front seat bottom raising member 10.
[0015]
Further, a heater duct 3 ′ connected to the heater unit 4 is connected to the front opening 11 a of the air passage 11 so as to blow warm air from the rear opening 11 b of the air passage 11 to the rear seat side. That is, the rear side opening 11b opens near the rear lower portion of the seat cushion 1a.
[0016]
Moreover, the lower area | region of the front seat 1 is made flat (flat) by providing the front seat lower raising material 10 in the lower part of the front seat 1. Then, the seat cushion 1a and the seat back 1b of the front seat 1 are folded as shown in FIG. 1, and the front seat 1 is supported so that it can be tumbled (arrow C).
[0017]
In the above configuration, according to the present invention, the warm air supplied from the heater unit 4 through the rear heater duct 3 ′ passes through the blower passage 11 and from the rear opening 11 b to the foot 100 placed on the carpet 6. It is blown near. As a result, the rear seats can be warmed by the warm air.
[0018]
In particular, in the present invention, the air passage 11 is formed with the extended portion 12 formed on the rear seat raising material 5 ′ only by adding the front seat lower raising material 10 disposed in the lower portion of the front seat 1. The rear heater duct 3 conventionally disposed in the lower region of the front seat 1 is omitted, and the configuration is substantially simplified. In this case, the conventionally used members such as the floor silencer 8 can be eliminated, and the number of parts can be reduced.
[0019]
Moreover, the space around the lower part of the front seat 1 can be effectively utilized by flattening the lower region of the front seat 1 and supporting the front seat 1 on the raising material 10 under the front seat so as to be tumbleable.
[0020]
The preferred embodiment of the present invention has been described above, but the present invention is not limited to the above-described embodiment, and can be appropriately changed within the scope of the present invention. For example, the specific shape (cross-sectional shape) of the air passage 11 is not limited to the illustrated example, and may be an arc shape or the like. Moreover, it is not restricted to the case of the single ventilation path 11, For example, it can also be branched and piped in the middle of the ventilation path 11 in the middle.
[0021]
【The invention's effect】
As described above, according to the present invention, in this type of rear heater duct blower structure, a blower passage for blowing warm air to the rear seat is formed with a simple configuration simply by adding the underseat under the front seat. can do. In that case, a conventionally used member such as a floor silencer can be omitted, and the number of parts can be reduced. In addition, the weight can be reduced and the cost can be reduced. Further, by flattening the lower region of the front seat and supporting the front seat so that it can be tumbled, the space around the lower portion of the front seat can be effectively utilized.
