The present invention relates to a massage chair, and more particularly to a massage chair having a heating pad to form a heating pattern by using carbon nanotubes to provide antibacterial deodorization and far-infrared radiation function.

Massage controls the modulation of a subject's body by applying various types of mechanical stimuli to a part of the body, such as kneading, pressing, pulling, knocking, or moving a part of the subject's body, It is a medical adjuvant therapy that helps circulation and relieves fatigue of the subject.

The increase in massage demand has led to an increase in demand for massage devices or massage devices that provide artificial massage functions for economic and time reasons. In other words, as the demand for relieving fatigue or stress while releasing muscles that are bound through massage increases, various massage devices in a time and cost-effective manner have been released. Any form of instrument, device, or device that performs massage without a separate masseuse through a mechanical device is referred to as a massage device.

As an example of such a massage device, a massage chair in which a user can comfortably sit and receive a massage is mainly used. As the demand for a massage device increases, various functions are required to relieve fatigue so that a user may relax more comfortably than a general massage function for a massage chair.

In general, the massage chair may include a massage module that directly massages the user's body and a control device that controls the operation of the massage module. The massage module provides an artificial stimulus to the user, for example, by inflating the airbag using air pressure or using a roller or the like to body parts such as the neck, shoulders, arms, hips, legs, and feet. Such massage chairs have already been developed and disclosed in various driving massage devices. For example, in the case of a massage chair using a roller, the massage roller is mounted on a rail of a lifting type and then moved along the user's body in the direction of the rail by the rotation of the driving motor to provide a stimulus to the user. As another example, a massage roller is mounted on a support that rotates about an axis of rotation, and then rotates a certain portion by rotation of a drive motor to provide a massage function.

In addition, as the functions that can be implemented by various types of massage devices are added to the massage chair, a massage chair that provides various functions such as a thermal massage function and a low frequency massage function is being developed.
