Description

Seat armrest height adjustment.

The present invention relates to a seat armrest height adjusting device, but is not limited in detail, but by installing a guide rail formed with a gear on one side of the seat, the height of the armrest is automatically adjusted using the actuator and the gear according to the physical condition of the seated person. It relates to a seat armrest height adjustment device configured to be adjusted by.

In general, the car is provided with a variety of amenities, the most common is the armrest. Such an armrest is, for example, installed in the center of the rear seat, or installed in a door or the like, and the passenger can mount his arm on the armrest so that the passenger can ride comfortably.

In recent years, such an armrest has also been installed in the front seats for the convenience of the front occupants of passenger cars. A perspective view showing such a general seat armrest is shown in FIG. 1.

According to FIG. 1, a guide rail 3 is installed or embedded in one side of the seat back 2 of the seat 1, and the armrest 4 may be adjusted up and down along the guide rail 3. To be installed. The stub of the slider 5 is moved along the guide rail 3, for example, so that the armrest 4 is deployed when in use and remains in contact with the side of the seatback 2 in a vertical state when not in use. The knob 6 is rotatably fixed to 5a).

However, the height of the seat armrest cannot be adjusted accurately and precisely.

That is, the height adjustment of the seat arm rest is controlled by the slider, the slider 5 is inserted into the stop groove (3a) formed in the guide rail (3), more specifically of the slider (5) Since the stopper 5b is adjusted in such a manner as to be inserted into the stop groove 3a formed in the guide rail at regular intervals, the height adjusting unit is relatively large in distance between the stop grooves 3a and the range is shown to be very narrow. .

Accordingly, the occupants having various physical conditions and witty habits of the arm could not adjust the height of the armrests according to their conditions, which caused a problem of traveling in an uncomfortable state.

In particular, since the height adjustment of the armrest is all adjusted manually, there is a problem that the adjustment method is very inconvenient.

Therefore, the present invention has been made to solve the above problems, the object of the present invention is a seat armrest height adjustment device that can adjust the seat armrest fine and precise while the height adjustment range of the seat armrest is wide To provide.

Another object of the present invention is to provide a seat arm rest height adjustment device capable of automatically adjusting the height of the seat arm rest.

Gear is installed, the seat armrest height adjustment device is provided, characterized in that consisting of; a drive unit that moves up and down in the guide rail unit in accordance with the operation of the actuator.

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

2 is an exploded perspective view of the seat armrest adjusting device according to the present invention, Figure 3 is a diagram showing the state of use of the seat armrest adjusting device according to the present invention installed on the seat.

2 and 3, the seat armrest height adjusting device according to the present invention is composed of a guide rail unit 10, an actuator 20 and a drive unit 30.

In more detail, the guide rail unit 10 includes a main body 11 having a first guide rail 12 and a second guide rail 13 formed on both sides thereof. In the guide rails 12 and 13 of the main body 11, teeth 12a and 13a are formed along the length thereof. The main body 11 is formed with a guide groove 14 having a predetermined length. The upper and lower parts of the main body are also provided with two fixing parts, for example, the upper fixing part 15 and the lower fixing part 16, which are fixed to the seatback side of the seat by bolts, for example.

The actuator 20 includes a rotating rod 21 rotatable in both directions, and the rotating rod 21 is inserted into a guide groove 14 formed in the main body 11 of the guide rail 10 to move up and down. Reciprocate. In addition, the end of the rotary rod 21 is preferably formed with a fixed end 22 to which the active gear of the drive unit to be described in detail is formed. In particular, the actuator 20 is connected to the operation switch 24 via a wire 23, which includes two operation buttons 24a and 24b and is installed on one side of the seat or on the armrest itself. Can be.

In addition, the drive unit 30 includes a main body 31 inserted into the guide rail unit 10. The main body 31 includes a front plate 32 and a rear plate 33. The stub 32a in which the seat armrest 4 is fixed by the knob 6 at the center of the front plate 32 is provided. Is formed. In addition, the main body 31 has a first kind gear gear which is geared to the teeth 12a formed on the first guide rail 12 of the active gear 34, the active gear 34 and the guide rail unit 10. 35), gears geared to the differential gear 36 geared to the active gear 34, and teeth 13a formed on the second guide rail 13 of the differential gear 36 and the guide rail unit 10. The second driven gear 37 to be coupled is rotatably installed. The first driven gear 35, the differential gear 36 and the second driven gear 37 of the gear set are rotatably fixed to the rear plate 33. However, the rotating shaft of the active gear 34 coincides with the guide groove 14 of the guide rail unit 10 and is particularly fixed to the fixed end 22 formed on the rotating rod 21 of the actuator 20. Accordingly, when the actuator 20 is operated to rotate the rotating rod 21, the seat armrest 4 fixed to the driving unit 20 is moved up and down along the guide rail unit 10.

In the operation of the seat armrest height adjusting device according to the present invention, in order to adjust the height of the seat armrest 4 after the occupant is seated on the seat 1, the operation button of the operation switch 24 installed in the seat position To operate.

For example, the button 24a is pushed to move the seat armrest 4 upward, and the button 24b is pushed down. Of course, the button 24a and the button 24b are configured to rotate the rotation rods 21 in opposite directions.

At the same time, the rotary rod 21 of the actuator 20 is rotated in one direction or the other direction, so that the active gear 34 is rotated in the same direction as the rotary rod.

At the same time, the first driven gear 35, the differential gear 36, and the second driven gear 37 are rotated in association with each other in a gear-coupled state. At this time, the first driven gear 35 follows the teeth 12a of the first guide rail 12, and the second driven gear 37 moves upward along the teeth 13a of the second guide rail 13. Or moved downwards.

In addition, the adjustment unit of the seat armrest can be in the range of one pitch of the gear, so that it can be adjusted to the fine position.

Accordingly, the driver or the passenger can fix the seat armrest in the optimum position according to the driver's physical condition and riding state.

As a result, when the seat armrest adjusting device according to the present invention is applied to the seat of the vehicle, the seat armrest can be adjusted simply by operating the operation switch in the seated state of the occupant, in particular, the upper and lower adjustment range is wide and the adjustment unit is Since the seat armrest can be precisely adjusted at the optimum position desired by the occupant, there is an effect of increasing convenience.

While preferred embodiments of the present invention have 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.
