Armrest apparatus for vehicles

1. An armrest apparatus for vehicles, comprising:

a body combined with a mounting area provided on a side surface of an interior of a vehicle to be slidably movable, and on which a passenger rests an arm;

a movement guide that protrudes from the body and is inserted into a mounting groove provided in the mounting area to guide movement of the body along the mounting groove; and

a mounting unit disposed in the mounting area and configured to:

support the body, and

fix a position of the body withdrawn from the mounting area through sliding movement by allowing the body to be inserted therein.

2. The armrest apparatus for vehicles of claim 1 , wherein the body includes:

a main body combined with the mounting area; and

a coupling member combined with a rear surface of the main body to protrude, and inserted into the mounting unit at one end of the mounting groove.

3. The armrest apparatus for vehicles of claim 2 , wherein the mounting unit includes:

a first guide groove that forms a first path in a direction of insertion of the coupling member;

a second guide groove that branches off from the first guide groove to extend upwards, and forms a second path depending on movement of the coupling member; and

a third guide groove that branches off from the first guide groove to extend downwards, and forms a third path depending on movement of the coupling member.

4. The armrest apparatus for vehicles of claim 3 , wherein each of the first to third guide grooves includes an engaging area having a shape that corresponds to a shape of an engaged piece provided at one end of the coupling member to engage the engaged piece with the inside of the engaging area.

5. The armrest apparatus for vehicles of claim 3 , wherein the coupling member protrudes to be inserted into the second guide groove or the third guide groove, thereby adjusting a height of the main body, and the protrusion of the coupling member is adjusted in stages.

6. The armrest apparatus for vehicles of claim 1 , wherein the body includes:

a main body combined with the mounting area and having a C-shape such that the mounting unit protruding from an inner surface of the mounting area is held therein; and

an insertion member disposed in the main body and selectively inserted into the mounting unit in response to sliding movement of the main body.

7. The armrest apparatus for vehicles of claim 6 , wherein the insertion member is formed of a magnetic material, and a position of the insertion member inserted into the mounting unit is fixed by magnetic combination between the insertion member and a magnet provided in the mounting unit.

8. The armrest apparatus for vehicles of claim 6 , wherein:

the insertion member is combined with a head of the mounting unit, as the insertion member is inserted into the mounting unit; and

an extension member connected to the head is received in an angle adjustment guide provided in the main body, as the main body is rotated about the insertion member to adjust an angle of the main body.

9. The armrest apparatus for vehicles of claim 8 , wherein the body further includes:

a fixing member in a folded state mounted on one surface of the main body, unfolded from the folded state due to a weight thereof to protrude, and inserted into an insertion recess provided in an inner surface of the mounting area, as the angle of the main body is adjusted through rotation of the main body.

10. The armrest apparatus for vehicles of claim 9 , wherein the fixing member has a length that selectively extends towards the insertion.
