BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a waist exercise chair and a rehabilitation exercise apparatus having the same,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a waist exercise chair and a rehabilitation exercise apparatus having the same, and more particularly, to a waist exercise chair and a rehabilitation exercise apparatus having a seat having a specific structure, .

As income has recently risen, interest in health and culture has risen, as well as in food and shelter culture. Among them, health is one of the most important topics of human beings that no one can overlook.

As such, health is very important to humans, and as interest in health has increased recently, there is also a growing interest in exercise equipment that maintains or improves health. Recently, health-related exercise apparatuses are constantly developed, mass-produced and distributed according to the public interest, and these exercise apparatuses are attracting great popularity from the public. Representative examples include functional chairs such as a fitness exercise chair, a massage chair, a horse riding exercise chair, a waist exercise chair, and the like. These functional chairs are very useful for healthy people as well as those who need rehabilitation.

Specifically, the conventional functional chair is a structure that twists the waist to the left and right (twist) and tilts the buttocks to induce waist movement. However, such a functional chair indirectly relaxes the back part of the spine, that is, the lumbar spine, but has a disadvantage that it can not relax directly and effectively. In addition, the conventional functional chair is a structure in which the seated person directly uses the abdominal muscles or the back muscles to induce relaxation and movement of the vertebrae. Therefore, the conventional functional chair has a disadvantage that it is very inconvenient and difficult for the elderly or persons with disabilities.

Therefore, there is a high need for a functional chair capable of directly and effectively relaxing the lumbar spine and exercising comfortably for the elderly or the handicapped who can not use the abdominal muscles or the back muscles properly, as well as healthy people.
