Abstract (en)
[origin: EP1941815A2] The servo mechanism (29) for a seat (14) of a chair (1) has a scissor-type articulated lever assembly (30, 30') which is connected to the seat part and a support frame (5) and includes several articulated lever elements. A spring assembly progressively applies a spring force upon the scissor-type articulated lever assembly so that a relative change in angular disposition between the lever elements applies a substantially constant force upon the seat part in every position of the seat part, where a travel distance of the seat part is greater than a spring travel of the spring assembly.
