Vehicle seat length adjustment mechanism with or without memory

摘要

A length adjustment mechanism (L1 to L3) or a memory length adjustment mechanism (M1 to M3) for conventional seat construction is insertable with conventional or round, closed pairs of rails (1,2) without structural alterations. The seat frame (3) for the purpose of increasing the stiffness is designed so that both seat rails (1,2) are connected with at least one cross arm (10b), on which one locking part is arranged and the other locking part.
