Office massage chair {office massage chair}

The present invention relates to a massage chair that, unlike existing massage chairs, does not occupy a large volume, can be installed in a narrow space, and can be used for office and high-end types through an efficient massage function.

A massage chair is a chair manufactured to mechanically provide a massage feeling at home or at work without a massage specialist. Since various driving devices such as an airbag and a massage ball are provided in the massage chair, the user receives a massage feeling such as pressure or heat by operating the massage chair after sitting on the massage chair.

A user who wants to receive a massage in the massage chair operates the massage chair by applying an operation signal through a control unit while sitting on the massage chair. After receiving the operation signal, the massage chair moves the backrest part and the leg fixing part at a predetermined angle to a preset initial position so that the user is in a comfortable state, and then starts the massage operation.

On the other hand, the demand for professional exercise equipment at home has recently increased. Exercises using professional exercise equipment are generally somewhat higher in intensity than exercises without exercise equipment, and since the user exercises alone without the help of a professional instructor, pre-exercise warm-up and post-exercise finishes are more important.

However, in the case of such a general conventional massage chair, the volume is large, and there is a disadvantage in taking up a lot of space in a not wide home space, so the development of a massage chair that can solve this problem is required.
