Description

Height adjustment device of car seat armrest {HIGH AND LOW CONTROL DEVICE OF SEAT ARMREST FOR VEHICLE}

The present invention relates to a height adjusting device for a vehicle seat armrest.

As is well known, the armrest is installed on the side of the seat back of the seat of the vehicle so that the passengers can rest comfortably to reduce the fatigue when traveling long distances, and when the passenger is seated on the seat as described above, The rest can be better rested by adjusting the height to match the passenger's physical condition.

The armrest height adjustment device of a vehicle for meeting the above demands is disclosed in Patent Document 1, the armrest height adjustment device of the vehicle is fixed to one side or both sides of the vehicle seat; An adjuster fixed to the fixing plate at a predetermined interval and having a plurality of fixing holes; A fixing pin installed in the adjuster so as to be movable up and down by a holder or the like and fixed to the fixing hole; The switching means for controlling the position of the fixing pin is installed, and it consists of a moving panel in which a bearing and an armrest (armrest) are installed at the lower end. By rotating the rotary switch of the switching means 90 degrees, the locking pin is unlocked from the fixing hole. After adjusting the height of the armrest by raising and lowering the adjuster, the rotary switch is rotated back to the original position so that the fixing pin is locked in the fixing hole.

However, the height adjustment device of the armrest of the vehicle is to adjust the height of the armrest after unlocking the fixing pin from the fixing hole by rotating the rotary switch 90 degrees, and the height adjustment operation of the armrest is complicated, and also the height adjusting device Since the armrest and the armrest are separated separately, there is a problem that the use of space is limited.

The object of the present invention is to provide a height adjustment device for a vehicle seat armrest that can easily adjust the height by rotating only the armrest by correcting the above problems.

In order to achieve the above object, the present invention is fixed to the seat back, the fixing plate formed a lock ball at regular intervals on both sides; A guide bracket inserted into the fixed plate so as to be lifted and formed with support holes on both sides thereof; Guide bracket control means for inserting a rocker having a cam in an opposite position to the guide bracket to support a lock pin wound around the rocker and the support hole; It is composed of an armrest that is supported on the outer surface of the guide bracket and fixed to the rocker by a support ring.

As described above, in the present invention, when the armrest is horizontal, the lock control means is in a locked state, and the height of the height is adjusted when the armrest is lifted after releasing the locking of the lock control means by raising the armrest vertically in the above state. The height and height of the armrests are simple, fast and compact in structure, occupying a small installation space. Therefore, the armrests can be easily installed without interfering with peripheral devices such as recliners when installed on the side of the seat back.

1 is an installation state of the armrest, Figure 2 is an exploded perspective view of an embodiment of the present invention, Figure 3 is a longitudinal cross-sectional view of the embodiment of the present invention in combination, 10 is a seat, 11 is a seat back, 20 is a armrest As the armrest 20 is installed to adjust the height on the side of the seat back (11).

23 is a fixing plate, the fixing plate 23 is closed on one side of the fixing plate body 24, the other side is partially open, lock balls (26a) (26b) at regular intervals on both sides (25a, 25b) In this case, the fixing plate 23 is provided with a support piece 27 in the closed portion and fixed to the seat back frame (not shown) by welding, bolts or the like.

29 is a guide bracket, the guide bracket 29 has one side of the bracket body 30 to open a part, and forms a hole 31 on the other side, and supporting holes 33a (32a) ( 33b) is formed and inserted and supported so that the fixed plate 23 can be elevated.

36 is a guide bracket control means, and the guide bracket control means 36 inserts a rocker 37 having cams 38a and 38b formed at opposite positions in the guide bracket 29 to the rocker 37. And lock pins 39a and 39b wound around coil springs 40a and 40b around the support holes 33a and 33b, so that cams 38a and 38b are locked pins 39a. Lock pins 39a and 39b protrude and are inserted into lock balls 26a and 26b so that the guide bracket 29 is locked, and the lock pins 39a and 39b are locked as the locker (39b). When the cams 38a and 38b of the 37 are in contact with the outer circumferential surface of the portion where the cams 38a and 38b are not formed, they are unlocked.

The armrest 20 forms a fixing hole 44 at one end of the armrest frame 43 to support the outer surface of the guide bracket 29 and then to the rocker 37 as a support ring 45. When the armrest 20 is horizontal, the cams 38a and 38b contact the lock pins 39a and 39b. When the armrests 20 are placed vertically, the lock pins 39a and 39b are cams. It is made to contact parts other than (38a) (38b).

The bushing 48 is inserted between the armrest frame 43 and the guide bracket 29 of the support ring 45 to smoothly rotate the armrest 20.

In the present invention as described above, when the armrest 20 is in the horizontal state, the cams 38a and 38b formed at opposite positions of the rocker 37 of the lock control means 36 are connected to the lock pins 39a and 39b. One end of the lock pins 39a and 39b is brought into contact with the lock balls 26a and 26b formed on both sides of the fixing plate 23 to restrain the guide bracket 29 to restrain the armrest 20. ) Is fixed to the seat back 11. (See Figure 4A)

When the armrest 20 is raised to adjust the height of the armrest 20 in the above state, the rocker 37 also rotates so that the cams 38a and 38b are separated from the lock pins 39a and 39b. The lock pins 39a and 39b are locked in the lock balls 26a and 26b by the elasticity of the coil springs 39a and 39b when the 38a and 38b contact the outer circumferential surface of the rocker 37 which is not formed. It is to be released to maintain the state supported by the support holes (33a) (33b) of the guide bracket 29 to release the restraint of the guide bracket (29).

After releasing the restraint of the guide bracket 29 from the fixing plate 23 as described above, the armrest 20 is moved up and down while maintaining the vertical state of the armrest 20, and thus the armrest 20 is lifted from the fixing plate 23. Height can be adjusted to a desired position, and when the armrest 20 is rotated horizontally, the cams 38a and 38b are in contact with the lock pins 39a and 39b and the lock balls 26a of the fixing plate 23. It is inserted in 26b, and the lock control means 36 is locked.
