Description

Technical Field

[0001] The utility model relates to the technical field of seats, in particular to a two-way waist protection seat. Background Art

[0002] A rocking chair is a leisure chair with a rocking structure that uses the force applied by the user to achieve a small swing. When the user sits on the rocking chair, the body can swing back and forth to relieve stress and relax the body and mind. The traditional rocking chair is designed with safety and comfort in mind, but when in use, due to the rocking chair's arc swing, when the rocking chair needs to be fixed forward or backward, the user needs to exert a lot of force on the waist to maintain the state of the rocking chair. On the other hand, when people work for a day, their bodies are in a relatively stiff state. When resting on the rocking chair, the traditional rocking chair can only be used to relax the body, but it cannot stretch and massage the body to relieve people's body stiffness. At the same time, it is necessary to solve the problem that the traditional massage chair is large in size and inconvenient to use. For students, the body is in the development stage. During the use of the chair, the sitting posture will have a certain impact on development. How to use the seat to standardize the sitting posture and avoid students from hunching over when using the seat? Most rocking chair frames are spliced ​​with wooden structures. After long-term use, their support stability will be affected to a certain extent.

[0003] The core of the seat design is that when a person sits on it, whether the body is sitting forward, leaning forward, or sitting back, the backrest will adaptively press against the back to prevent hunchback.
