Swivel office chair

摘要

The backrest has at a predetermined vertical spacing (a) from the seat surface (1), a horizontal bending joint (17) which is designed to yield and which automatically blocks in the swivel end position of the backrest . Where the seat and backrest are upholstered, the vertical distance (a) of the joint (17) from the depressed cushion corresponds to the ergonomic definitions available. The seat joint is set level or slightly above or below the part of the backrest cushion which protrudes furthest inwards when the backrest is not compressed.
