Abstract
An armrest assembly includes: an arm frame body having formed therein an inner space with an open upper end, and mediating coupling to a seat portion; an inner body which is inserted to be arranged in the inner space of the arm frame body, and is arranged to be movable in up and down directions according to the manipulation of a user; an arm support pad which is connected to the upper portion of the inner body, on which the arm of the user is placed and supported, and which has a front end portion rotatable in the left and right horizontal directions due to an external force provided by the user; and a frictional ring which provides the frictional force between the inner body and the arm support pad.

An armrest assembly comprising:
- an arm frame body in which an inner space with an open upper end portion is formed and which mediates coupling to a seat part on which a user sits;
- an inner body disposed by being inserted into the inner space of the arm frame body and disposed to be moved vertically by the user's manipulation;
- an arm support pad which is connected to an upper portion of the inner body, on which the user's arms are supported by being rested, and which is provided to have a front end portion rotated by an external force provided by the user in a horizontal direction;
- and
- a frictional ring disposed between the inner body and the arm support pad and providing a frictional force between the inner body and the arm support pad when the arm support pad rotates with respect to the inner body,
- wherein the frictional force by the frictional ring is determined by an assembly force of a hinge screw connecting the inner body to the arm support pad,
- wherein the inner body is provided with a screw fastening boss in which a screw fastening hole is formed, and the arm support pad is provided with a screw through boss in which a screw through hole is formed at a position corresponding to the screw fastening hole, and
- the frictional ring is compressed as a ring-shaped compression boss formed to protrude to the lower portion of the arm support pad is moved downward by an assembly force of the hinge screw fastened to the screw fastening hole of the screw fastening boss through the screw through hole of the screw through boss.
A chair comprising:
- a seat part provided so that a user sits thereon;
- and
- an armrest assembly provided on both left and right end portions of the seat part and provided so that the user's arms are rested,
- wherein the armrest assembly includes:
- an arm frame body in which an inner space with an open upper end portion is formed and which mediates coupling to the seat part;
- an inner body disposed by being inserted into the inner space of the arm frame body and disposed to be moved vertically by the user's manipulation;
- an arm support pad which is connected to an upper portion of the inner body, on which the user's arms are supported by being rested, and which is provided to have a front end portion rotated by an external force provided by the user in a horizontal direction;
- and
- a frictional ring disposed between the inner body and the arm support pad and providing a frictional force between the inner body and the arm support pad when the arm support pad rotates with respect to the inner body,
- wherein the frictional force by the frictional ring is determined by an assembly force of a hinge screw connecting the inner body to the arm support pad,
- wherein the inner body is provided with a screw fastening boss in which a screw fastening hole is formed, and the arm support pad is provided with a screw through boss in which a screw through hole is formed at a position corresponding to the screw fastening hole, and
- the frictional ring is compressed as a ring-shaped compression boss formed to protrude to the lower portion of the arm support pad is moved downward by an assembly force of the hinge screw fastened to the screw fastening hole of the screw fastening boss through the screw through hole of the screw through boss.
