Eine Rückenlehne für einen Sitz, insbesondere einen Kraftfahrzeugsitz.

摘要

The spring structure of the backrest includes a strip member (5) positioned so as to provide lumbar support for the back of the seat occupant. The member is generally butterfly-shaped and is constituted by at least two parts (51, 52) connected (7) to each other so as to be able to adapt themselves to the back of the seat occupant.
