Abstract

The present disclosure provides an armrest-locking device that is disposed in an armrest that is stowed in an armrest case of a rear seatback. The armrest-locking device includes: a locking member disposed at any one of the armrest case and the armrest; a locking bracket rotatably coupled to the other one of the armrest case and the armrest, the locking member inserted into a groove formed on a peripheral portion of the locking bracket when the armrest is stowed; and a holding bracket. In particular, the locking bracket rotates in a forward direction to be fastened to the locking member when the locking member is inserted; and the holding bracket has an end to engage with the locking bracket when the locking bracket is rotated, maintaining the rotation state of the locking bracket.

First claim

The invention claimed is:

1. An armrest-locking device disposed in an armrest and configured to be stowed in an armrest case of a rear seatback, the device comprising:
a locking member disposed at one of the armrest case or the armrest;
a locking bracket rotatably coupled to the other one of the armrest case or the armrest and having a groove formed on a peripheral portion of the locking bracket, wherein the locking member is configured to insert into the groove of the locking bracket while the locking bracket rotates in a forward direction toward a stowed position of the armrest, and the locking bracket is fastened to the locking member when the locking member is fully inserted into the groove; and
a holding bracket having an end configured to move relative to the locking bracket while continuously supporting the locking bracket when the locking bracket is rotated, thereby maintaining a rotation state of the locking bracket.

2. The device of claim 1 , wherein the locking bracket is provided in a pair and the pair of locking brackets are disposed at positions corresponding to both sides of the armrest.

3. The device of claim 1 , wherein the holding bracket is configured to be rotatably hinged to the armrest case or the armrest.

4. The device of claim 3 , wherein a first protrusion is formed on a peripheral portion of the locking bracket and is configured to engage with a second protrusion formed on a peripheral portion of the holding bracket.

5. The device of claim 4 , further comprising a first elastic portion configured to apply a backward torque to the locking bracket when the locking bracket is rotated forward, and a second elastic portion configured to apply a forward torque to the holding bracket when the holding bracket is rotated backward.

6. The device of claim 5 , wherein when the locking member is not inserted into the groove, a backward side of the second protrusion is in contact with a forward side of the first protrusion, so that a forward rotation of the locking bracket is inhibited, and when the locking member is inserted into the groove, a forward side of the second protrusion is in contact with a backward side of the first protrusion, so that a backward rotation of the locking bracket by the first elastic portion is inhibited.

7. The device of claim 6 , wherein when the forward side of the second protrusion is in contact with the backward side of the first protrusion so that a contract surface is formed, a virtual line perpendicular to the contact surface goes through a rotational center of the holding bracket.

8. The device of claim 4 , wherein wires are connected to a peripheral portion of the holding bracket and configured to rotate the holding bracket backward when being pulled.

9. The device of claim 1 , wherein the locking member is formed in a shape of a bar and is inserted into the groove in a direction perpendicular to an axial direction of the locking member.
