Device for attaching the back of a seat to a supporting arm

摘要

The device has a backrest with a rigid bottom plate (5) and an elastic compressible mounting pad (6) interposing between the rigid plate and fixation slot that fixes a supporting arm (1) to the plate. The plate is fixed at the arm by a fixation unit permitting angular displacement of the plate with respect to the arm between the compressionless position of the pad and compression position of the pad. The pad is inserted in a housing (17).
