Kind Code:
A1
Abstract:
A chair with an elastic lifting seat pan, which comprises a chair body (10), a transmitting component (20), a driving component (30), and a seat pan (15) firmly connecting plane connecting seat of a pair of link plates (24) of the transmitting component (20). When the user is seated on the seat pan (15), the torsion spring (33) is deformed with the rotation of the spindle (34), accumulating elastic potential energy and damping the descent of the seat pan (15). When the user stands up from the seat pan (15), the torsion spring (33) releases the elastic potential energy to drive the spindle (34) reversely and help the user to stand up. The chair with an elastic lifting seat pan can be used to help the elderly and the weak people, and also to relax in public places and leisure places to reduce fatigue.
