DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rear heater unit mounting structure for a vehicle rear heater.

[0002]

2. Description of the Related Art Generally, as shown in FIG. 3, a conventional rear heater for a vehicle includes a rear heater unit 2 installed under a front seat (seat) 1 and a hot air from the rear heater unit 2 provided in the rear seat. 3 and a heat control panel 5 mounted on the rear heater duct 4 for controlling the temperature of hot air from the rear heater unit 2. I have.

The rear heater unit 2 sends air sent by a blower 6 for blowing air to a heater core 7 side into which hot water is introduced and a bypass side of the heater core 7 by adjusting the opening of an air mix damper (not shown). On the other hand, the air is distributed in a desired ratio to generate wind at a temperature required by the occupant. In the figure, 18 is the heater core 7
Hot water supply pipe that supplies hot water after cooling the engine to
Reference numeral 17 denotes a hot water discharge pipe for discharging hot water from the heater core 7.

The heat control panel 5 is for adjusting the opening of the air mix damper of the rear heater unit 2 and, as shown in FIG. 3, a control cable 8 connected to the air mix damper. The outer cable 8a is fixed to the clamp 9 of the control panel main body 5a, and the inner cable 8b of the control cable 8 is connected to the operating portion 5c of the adjustment lever 5b pivotally attached to the control panel main body 5a. With a plurality of (three in the example in the figure) fastening bosses 10 projecting from the upper surface, a plurality of fastening holes 11 of the control panel body 5a are aligned with a fastening member 12 such as a tapping screw. By tightening, the control panel main body 5a is fixed on the rear heater duct 4, and the tip of the adjustment lever 5b is fixed. The slit 15 of the heat control plate 14 assembled to the rear console 13
The control knob 16
Are fitted. In the drawing, reference numeral 19 denotes a vehicle-side harness for supplying electric power to the rear heater unit 2;
Is a blower switch for turning on and off the blower 6 of the rear heater unit 2.

As shown in FIGS. 3 and 4, a seat cloth 22 for reinforcing the seat and extending in the width direction of the vehicle is provided at a position on the front side of the lower portion of the front seat 1 on the floor 21 of the vehicle. , The rear heater unit 2 includes:
The front end is fixed to the upper surface of the seat cloth 22 by fastening members 25 such as tapping screws via fixing brackets 23 and 24 provided on the left and right sides of the upper surface of the blower 6. The rear end portion is fixed to the floor 21 by a fastening member 27 such as a tapping screw via a fixing bracket 26. As shown in FIG. 3, the hot water supply pipe 18 and the hot water discharge pipe 17 are guided to a lower side of the floor 21 via a mounting lid 29 through a through hole 28 formed in the floor 21. .

As shown in FIG. 4, a conventional ordinary seat cloth 22 is formed by welding 31 on the upper surface of a floor 21 to the front and rear ends of a reinforcing member 30 having a convex shape on the upper side and extending in the width direction of the vehicle. The rear heater unit 2 is arranged so that the front end on the blower 6 side approaches the rear surface 22 a of the seat cloth 22.

[0007]

However, as described above, since the rear heater unit 2 is arranged so that the front end thereof approaches the rear surface 22a of the seat cloth 22, as described above, when the rear heater unit 2 is seated on the rear seat 3. Then, as shown in FIG.
The rear end protrudes, which is a hindrance and has the disadvantage of making the seating uncomfortable. At this time, if the size of the rear heater unit 2 can be reduced, the above-mentioned problem can be solved.
There was a problem that the target performance could not be achieved.

In view of the above circumstances, the present invention provides a vehicle in which the rear heater unit, which is sized to maintain the target performance, can be moved forward so that a foot space for the rear seat can be secured. It is an object of the present invention to provide a rear heater unit mounting structure for a rear heater.

[0009]

SUMMARY OF THE INVENTION The present invention provides a rear heater for a vehicle, comprising: a rear heater unit installed under a seat; and a rear heater duct for guiding warm air from the rear heater unit to a rear seat. In the heater unit mounting structure, an opening is formed on the rear surface of the sheet cloth disposed on the lower front side of the seat, and the front end of the rear heater unit is inserted into the sheet cloth from the opening and mounted. And a rear heater unit mounting structure for a vehicle rear heater.

According to the above means, the following effects can be obtained.

An opening is formed on the rear surface of the sheet cloth,
When the front end of the rear heater unit is inserted and arranged in the seat cloth from the opening, the position of the rear heater unit can be changed forward, so that the rear heater unit has a size enough to maintain the target performance. In this state, it is possible to prevent the rear end of the rear heater unit from protruding to the foot of the rear seat, and to secure a foot space for the rear seat.

[0012]

Embodiments of the present invention will be described below with reference to the drawings.

FIGS. 1 and 2 show an example of an embodiment of the present invention. In the drawings, the parts denoted by the same reference numerals as those in FIGS. 3 and 4 represent the same parts.

The feature of this embodiment is that, as shown in FIGS. 1 and 2, the rear end of the reinforcing member 30 of the sheet cloth 22 arranged on the lower front side of the front seat (seat) 1 is shown in FIG. By curving upward as shown
An opening 32 is formed on the rear surface 22a of the sheet cloth 22.

On the other hand, the front end (the blower 6 side) of the rear heater unit 2 disposed below the front seat 1 is inserted into the seat cloth 22 from the opening 32 and fixed. At this time, fixing brackets 23 and 24 for fixing the front end of the rear heater unit 2 to the seat cloth 22 are
It is mounted at a position shifted rearward from the front end so as not to interfere with the reinforcing member 30.

As described above, the rear surface 22 of the sheet cloth 22
a, the front end of the rear heater unit 2 is inserted into the seat cloth 22 from the opening 32, so that the installation position of the rear heater unit 2 is changed to the front. Therefore, while giving the rear heater unit 2 a size that maintains the target performance,
The rear heater unit 2 is prevented from protruding from the feet of the rear seat 3, so that a large foot space of the rear seat 3 can be secured, and the sitting comfort of the rear seat 3 can be improved.

The mounting structure of the rear heater unit of the vehicle rear heater according to the present invention is not limited to the above-described example, and the shape of the reinforcing member forming the opening on the rear surface of the seat cloth is variously changed. For example, an opening through which the front end of the rear heater unit can be inserted may be formed in the reinforcing member, and it is a matter of course that various modifications can be made without departing from the gist of the present invention. .

[0018]

As described above, according to the rear heater unit mounting structure for a vehicle rear heater of the present invention, an opening is formed on the rear surface of the seat cloth, and the front end of the rear heater unit is moved away from the opening. Since the rear heater unit is placed inside the seat cloth, the installation position of the rear heater unit can be changed to the front, so that the rear heater unit has a size that maintains the target performance, The rear end of the heater unit is prevented from protruding, so that a large foot space for the rear seat can be secured, and an excellent effect that the sitting comfort of the rear seat can be improved can be achieved.
