Description

Air Armrest Device.

The present invention relates to an air armrest device, and more particularly, to an air armrest device configured to contract and expand an armrest using a blower installed in a heating and cooling system.

In general, but not limited to, the rear seats of medium and large cars are provided with armrests, allowing rear seat passengers to travel comfortably with their arms seated. An exploded perspective view of a rear seat showing such a typical arm rest is shown in FIG. 1, according to FIG. 1, the arm rest 1 is formed with a receiving groove formed at the center of a seat back 2 of the rear seat. It is inserted rotatably in 2a).

Accordingly, when the occupant wants to use the armrest 1, the armrest is placed in the seat cushion 3 by rotating the armrest from the receiving groove 2a.

However, such an armrest has an advantage in that it provides the convenience of the occupant, but in particular, the receiving groove 2a is exposed to the outside during use, thereby deteriorating the aesthetics of the seat and the overall aesthetics of the interior of the vehicle.

In addition, the armrest is formed of a hard material was not a sufficient buffering effect there was a somewhat uncomfortable point.

The present invention is devised to solve these problems, the object of the present invention, air that can shrink or inflate the armrest by the operation of the blower of the heating and cooling system to provide a good cushion without harming the aesthetics in use An armrest device is provided.

This object is achieved by a preferred embodiment of the present invention, in accordance with an aspect of the present invention, the armrest is inserted into the receiving groove of the seatback of the sheet expandably therefrom; A first branch pipe connected to the armrest and connected to an intake duct of a heating and cooling system, a second branch pipe connected to an exhaust duct, and an air supply pipe communicating with the arm rest, wherein the first branch pipe and the second branch pipe are connected to the arm rest. An air supply duct provided at a branch portion with the branch pipe, and a second valve provided at the air supply pipe; Each valve installed in the air supply duct, a third valve installed in the suction duct of the cooling and heating system, a fourth valve installed in the discharge duct, and a blower of the air conditioning system are respectively connected to control the opening and closing of the valve and the operation of the blower. Electronic control unit; And a control switch connected to the electronic control unit and including a positive (+) button for inflating the armrest and a negative (-) button for contracting the armrest; Provided is an air armrest device, characterized in that consisting of.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

2 is a configuration diagram of the air armrest device according to the present invention, Figure 3 and Figure 4 is a cross-sectional view showing a state in which the air armrest according to the present invention contracted and expanded.

2, 3 and 4, the air armrest device according to the present invention includes an air armrest 10, air supply duct 20, the electronic control unit 30 and the operation switch 40.

In more detail, the air armrest 10 is made of an expandable elastic material so as to be fully inserted into the receiving groove of the seatback 2 of the seat in the contracted state and to be extended and disposed on the seat cushion in the expanded state. It is preferably formed.

An air supply duct 20 is connected to the air armrest 10, and the air supply duct 20 includes a first branch pipe 21 and a second branch pipe 22. The branch 23 of the branch pipes 21 and 22 is provided with a first valve 24 to selectively open and close the respective branch pipes 21 and 22. In addition, the air supply duct 20 includes an air supply pipe 25, one end of the air supply pipe 25 communicates directly with the air armrest 10, and a second valve is provided in the air supply pipe 25. (26) is provided.

Of course, a blower (B) is installed between the suction duct (ID) and the discharge duct (ED) of the air conditioning system to supply hot, cold or outdoor air to the room.

Optionally, a third valve 27 inside the suction duct ID and a fourth valve inside the discharge duct ED in order to accurately and quickly supply air to and from the supply duct 20. 28) is arranged.

Each of the valves 24, 26, 27, 28 is preferably formed as, for example, a gate valve, but other types of valves may be used as long as the respective ducts and pipes can be opened and closed.

In addition, each of the valves 24, 26, 27, 28 is connected to the electronic control unit 30, the opening and closing is adjusted respectively. Of course, the blower (B) is also connected to the electronic control unit 30, the operation is adjusted.

In addition, the electronic control unit 30 is connected to the operation switch 40, the operation switch 40 is composed of a positive (+) button 41 and a negative (-) button 42, air armrest The positive (+) button 41 is pressed when inflating (10), and the negative (-) button 42 is pressed when contracting.

In the operation of the air armrest device according to the present invention, in the state in which the air armrest 10 is inserted and maintained in the receiving groove of the seatback 2 of the seat in a contracted state (see Fig. 3), the occupant or driver Presses the positive (+) button 41 of the operation switch 40, the electronic control unit 30 rotates the first valve 24 to close the first branch pipe 21, and the second valve 26. To open the air supply pipe 25 and at the same time rotate the blower (B).

In addition, at this time, the third valve 27 is opened and the fourth valve 28 is closed by the electronic control unit 30 for the rapid supply of air.

Accordingly, the air is sucked by the suction duct ID by the blower B, as shown in FIG. 4, in the direction of the arrow A1 through the discharge duct ED, the second branch pipe 22, and the supply pipe 25. Is supplied into the air armrest 10 to expand the air armrest 10.

Therefore, the air armrest 10 is extended from the receiving groove of the seat back 2 and placed on the seat cushion. After the armrest 10 is expanded to a proper level, the operation of the blower B is stopped by the control unit 30 and the second valve 26 closes the air supply pipe 25 to close the armrest 10. Keep inflated.

Conversely, when the negative button 42 of the operation switch 40 is pressed to retract the armrest 10 into the receiving groove of the seat back 2, the electronic control unit 30 operates the first valve 24. ), The blower B is rotated while the first branch pipe 21 is opened, the second branch pipe 22 is closed, and the second valve 26 is opened. Of course, in this case, it is preferable to close the third valve 27 and open the fourth valve 28 in order to quickly and accurately discharge the armrest 10.

Accordingly, the air is blown out by the blower B from the armrest 10 through the supply pipe 25, the first branch pipe 21, and the suction duct ID as shown by the arrow A2, through the discharge duct ED. Discharged. Thus, the armrest 10 is contracted and completely received into the receiving groove of the seatback 12.

As a result, when the air armrest device according to the present invention is installed in an automobile, the armrest can be automatically inflated or shrunk by using the blower of the air conditioning system and thereby or the exhaust air, so that the armrest can be conveniently used. In addition, unnecessary space is not exposed to the seat back both in the contracted and expanded state, thereby providing beauty of the whole sheet.

Although a preferred embodiment according to the present invention has been described above, it will be understood by those skilled in the art that various modifications and changes can be made without departing from the scope of the appended claims.
