Abstract

A heating assembly for a massage chair, wherein a heating element is separately operated. The heating assembly according to an embodiment having a first bracket with a plurality of massage balls rotatably mounted to the first bracket. A massage assembly is fixed to the first bracket and can perform at least one of up-and-down and left-and-right motions. A second bracket is mounted to the massage assembly or the first bracket A support part inserted at one end thereof into the second bracket. A heating element is mounted to the support part and an airbag is fixed to the support part so as to be opposite to the heating element. Wherein the heating assembly is mounted inside the backrest of a massage chair.

First claim

The invention claimed is:

1. A heating assembly, comprising:
a massage assembly which is mounted inside a backrest of a massage chair, and which is capable of at least one of up-and-down and left-and-right motions;
a first bracket mounted to the massage assembly and moving with the massage assembly;
a plurality of massage balls rotatably mounted to the first bracket;
a second bracket mounted to the first bracket and having a guide groove formed therein;
a support part including a mounting protrusion to be inserted into the guide groove;
a heating element facing the massage ball with the first bracket and the second bracket interposed therebetween, mounted on one end of the support part to be spaced apart from the second bracket by a predetermined distance, and receiving power to generate heat; and
an airbag mounted on the other end of the support part so as to face the heating element between the support part,
wherein the mounting protrusion of the support part moves along the guide groove according to the amount of air injected into the airbag, and
the heating element is movable in a first direction toward the backrest of the massage chair and in a second direction opposite to the first direction.

2. The heating assembly of claim 1 , wherein the amount of air of the airbag is adjusted in multiple stages.

3. The heating assembly of claim 1 , wherein, when a stretching mode is applied to the massage chair, the air is filled into the airbag.

4. The heating assembly of claim 1 , wherein, when the heating element is heated, the air is filled into the airbag.

5. The heating assembly of claim 1 , wherein the heating element includes a heating wire provided therein.

6. The heating assembly of claim 1 , wherein the first bracket includes a mounting groove formed therein, and
the second bracket is mounted in the mounting groove.

7. A massage chair comprising the heating assembly of claim 1 , comprising:
a seat;
the backrest rotatably fixed to one side of the seat;
a leg fasten part rotatably fixed to the other side of the seat;
a support frame for fixing the seat;
the heating assembly mounted into the backrest and capable of at least one of up-and-down and left-and-right motions with the massage assembly; and
an operation unit capable of adjusting a rotation of the backrest, a rotation of the leg fasten part, and the up-and-down motion or the left-and-right motion of the massage assembly, and adjusting a heat generation of the heating element.

8. The massage chair of claim 7 , wherein the operation unit causes the heating element of the heating assembly to be reciprocated between a first direction toward the backrest and a second direction opposite to the first direction, by adjusting an amount of air of the airbag.

9. The massage chair of claim 7 , wherein the operation unit causes the heating assembly to move in a first direction toward the backrest and a second direction opposite to the first direction by adjusting an amount of air of the airbag.
