Description

[Detailed Description of the Invention] This invention relates to an armrest for an automobile that efficiently blows outside air, hot air or cold air from an air conditioner to the vicinity of the seating area of the seat without dispersing it into the interior of the car.

As a conventionally known armrest for automobiles, there is one shown, for example, in Japanese Utility Model Publication No. 54-24418.

However, in the case of such conventionally known armrests for automobiles, air circulation openings are provided on the opposing surfaces of the front pillar and the door body, and air outlets are formed on the armrest on the upper surface of the armrest attached to the door body. The outside air introduced into the front pillar from the ventilation duct installed in the instrument panel, or hot or cold air from the air conditioner, is guided into the door body through each distribution port, and the air is routed from inside the door body through the armrest. Since the air is blown out from the air outlet, there are many joints that guide the air from the ventilation duct to the air outlet on the armrest, and each of these joints obstructs the airflow, reducing the efficiency of airflow and making it difficult to sit on the seat. There was a problem in that sufficient ventilation could not be ensured near the area.

This idea was created by focusing on these conventional problems, and was designed so that when the door is closed, the opening at one end is directly connected to the outlet opening of the ventilation duct installed in the instrument panel. The object of the present invention is to solve the above-mentioned problems by attaching the armrest body to the indoor side of the door and providing the armrest body with an air outlet communicating with the opening.

This invention will be explained below based on the drawings.

1 to 6 are diagrams showing an embodiment of this invention.

First, the configuration will be described. Reference numeral 1 is an instrument panel, 2 is a front door, and 3 is a rear door.

A front armrest main body 4 having a U-shaped cross section is attached to the door trim 2a of the front door 2 so as to close the open side thereof. Openings 5a and 5b are formed in the front end 4a and the rear end 4b of the front armrest main body 4, respectively, and in the side part 4c of the front armrest main body 4, a side part of an occupant seated on the front seat 6 is formed near the rear thereof. A large number of holes 7a, 7b,...
An air outlet 7 is formed.

A ventilation notch opening 8 is formed in the instrument panel 1 and is directly connected to the opening 5a when the front door 2 is closed. The ventilation notch opening 8 is communicated with an outlet opening 9a of a ventilation duct 9 of an air conditioner (not shown) disposed within the instrument panel 1.

On the inner surface of the lower portion 4e, opposing protrusions 10, 10 are provided protruding from the sides 4c, respectively. An air outlet adjustment plate 11 is slidably provided to be guided by the protrusions 10 and 10 and come into contact with the inner surface of the side portion 4c near the air outlet 7.

The outlet adjusting plate 11 has a large number of holes 12b, 12.
b,..., an adjustment plate main body 12 having an adjustment knob 12a, an arm plate 13, and a duct opening/closing plate 14
It is integrally molded with a thin resin hinge 15 so that it can be bent freely. The adjustment knob 12a
protrudes from a cutout 4f provided in the side portion 4c of the front armrest main body 4. Further, the end portion of the duct opening/closing plate 14 is pivotally connected between the upper portion 4d and the lower portion 4e of the rear end portion 4b of the front armrest main body 4.

A connecting duct 17 is attached to the pillar trim 16a of the center pillar 16 and communicates with the opening 5b of the rear end 4b of the front armrest body 4 when the front door 2 is closed.

Further, a rear armrest main body 18 having a U-shaped cross section is attached to the door trim 3a of the rear door 3 so as to close the open side thereof. An opening 18c is formed in the front end 18a of the rear armrest main body 18 and communicates with the connection duct 17 when the rear door 3 is closed, and the rear end 18b is closed. In the side part 18d of the rear armrest main body 18, there is an air outlet 1 having a large number of holes 19a, 19a, .
9 is formed.

Further, the rear end 4b of the front armrest main body 4 and the connecting duct 17 are connected in communication with each other by a slide duct 22 penetrating in the front-rear direction when the front door 2 is closed. The slide duct 22 is provided with a guide slit 22a that is inclined with respect to the longitudinal direction of the vehicle body.

3a.

Note that although the case where four doors are used has been described above, in the case of a so-called two-door car with two doors, the front door 2 is simply a door.

Next, the action will be explained.

First, the air coming out of the ventilation duct 9 in the instrument panel 1 is directed to the front end 4a of the front armrest main body 4, which is directly connected to the ventilation notch opening 8.
The air enters the front armrest body 4 through the opening 5 , passes through the front armrest body 4 , and is blown out from the air outlet 7 .

If you want to send air only to the front seat 6, operate the adjustment knob 12a and adjust the adjustment plate body 1.
2 to the right, that is, toward the rear armrest main body 18, and align the many holes 7a of the air outlet 7 with the many holes 12b of the adjustment plate main body 12, as shown in FIG. 3, and rotate the duct opening/closing plate 14. Opening 5 in rear end 4b of front armrest main body 4
b is closed and the ventilation duct 9 is opened only from the air outlet 7.
Blowing out air from the

If you want to send air to both the front seat 6 and the rear seat, operate the adjustment knob 12a to move the adjustment plate body 12 to the left from the state shown in FIG. The alignment of the large number of holes 12b of the adjustment plate main body 12 is slightly shifted from 7a to make the opening smaller, and the duct opening/closing plate 14 is rotated to leave the opening 5b in a half-open state to allow air to flow through the slide duct 22 and the connecting duct 17. It is also sent into the rear armrest main body 18 through the air, and is also blown out from the rear air outlet 21 of the rear armrest main body 18.

Furthermore, if you want to send air only to the rear seat, operate the adjustment knob 12a and move the adjustment plate main body 12 to the third position.
Move it to the left from the state shown in the figure, close the many holes 7a of the air outlet 7 with the part of the adjustment plate main body 12 where there are no holes 12b, and move the duct opening/closing plate 14 to the side 4.
c until the opening 5b is fully open and the air outlet 19 of the rear armrest main body 18 is opened.
Let the wind blow only from.

Next, the operation of the slide duct 22 will be explained.

As shown in Fig. 3, when the front door 2 is closed, the duct operating shaft 23 protruding outward from the center pillar 16 is pushed by the end of the door panel 2c of the front door 2 and moves into the slide duct 22 against the biasing force of the spring 24.
As a result, the slide duct 22 moves leftward, i.e., toward the front armrest main body 4, and is connected in a communicating state with the opening 5b at the rear end 4b of the front armrest main body 4.

When the front door 2 is opened in the opposite direction, the duct operating shaft 23 projects its tip to the outside of the center pillar 16 due to the elasticity of the spring 24. At this time, as the drive pin 23a of the duct operating shaft 23 moves upward in the figure, the slide duct 22 moves to the right, that is, to the connecting duct 17 side, and separates from the rear end 4b of the front armrest main body 4. It becomes possible to open the front door 2.

FIG. 6 shows a modified example of a moving mechanism for the slide duct 32.

The duct operating shaft 30 is attached to the center pillar 16 so as to be able to move forward and backward in the vehicle width direction, and an L-shaped link 31 whose one end abuts the end of the duct operating shaft 30 located inside the center pillar 16 rotates. It can be installed freely. The drive pin 31a provided at the other end of the link 31 is connected to the vertical guide slit 3 provided in the slide duct 32.
It is inserted in 2a.

Further, the duct actuating shaft 30 is always energized by a spring 33 wound around the link 31 so that its tip protrudes toward the outside of the center pillar 16 and draws the slide duct 32 toward the connecting duct 17 side.

The operation of this variation is based on the duct actuation shaft 30
When the front door 2 opens and closes, the center pillar 1
6 and rotates the link 31, and this rotation also causes the drive pin 31a at the tip of the link 31 to rotate.
moves the slide duct 32 forward and backward in the direction of the arrow.
Therefore, when the front door 2 is opened, the slide duct 32 is separated from the front armrest body 4, and when it is closed, it is connected to the front armrest body 4.

As explained above, according to this idea,
The armrest body is attached to the indoor side of the door so that the opening at one end is directly connected to the outlet opening of a ventilation duct arranged in the instrument panel when the door is closed, and the armrest body communicates with the opening. Since the configuration is equipped with an air outlet, the air can be guided directly into the armrest body from the outlet of the ventilation duct in the instrument panel and blown out from the outlet provided in the armrest body, compared to conventional methods. This improves air blowing efficiency and ensures sufficient air blowing to the vicinity of the seating area of the seat. Therefore, appropriate air can be blown near parts of the human body that are prone to sweating, and comfortable air conditioning can be achieved.

In addition, the structure is extremely simple, the number of parts is reduced, and the economical effect is great.
