Description

Technical Field

[0001] This application belongs to the field of seating manufacturing technology, specifically relating to a reclining device for a reclining chair and a reclining chair. Background Technology

[0002] In the current technology, with the improvement of living standards, people have higher and higher requirements for the user experience of seating. At present, the rocking chair is a seat used to relax the body in life. When the user sits in the rocking chair, he / she can adjust his / her center of gravity to achieve the function of rocking back and forth, thus relaxing the user's body. It is widely used in homes, offices, cars and airplanes.

[0003] In existing technology, to achieve the backrest function (swinging back and forth) of a chair, a typical backrest chair includes a base, a backrest on the base, and curved legs located under the seat. By having the curved surface contact a reference surface, the user can adjust their center of gravity to achieve the backrest function. The main drawbacks of this structure are: firstly, to increase the swing amplitude, a certain degree of curvature in the curved legs is required, significantly increasing the seat's floor space; secondly, the seat lacks damping during the swinging process, resulting in a rather stiff swing and a poor user experience. Furthermore, it is impossible to adjust the seat parameters during the swinging process to meet the needs of users of different heights and weights. Therefore, improvements are urgently needed.
