AI Technical Summary

Technical Problem

The existing chair components lack flexibility and comfort when adjusting the backrest and seat positions, especially in the conversion process from the upright position to the backrest position, which makes it difficult to meet the different usage needs of users.

Method used

A chair assembly including a base structure, a seat support structure and a backrest support structure is designed. Through the cooperation of multiple pivot points, independent adjustment of the seat and the backrest and overall backrest movement are achieved. The assembly also introduces a control coupling and bias assembly that controls the back tilt rate of the backrest support structure and the back tilt motion of the seat support structure by adjusting the bias pressure and coupling angle.

Benefits of technology

It realizes flexible conversion between the chair assembly between upright and backward positions, improves user comfort and operation convenience, and meets the height and weight needs of different users.
