Motor vehicle car seat adjustment mechanism has a coupling and switching mechanism that allows switching between fixed and adjustment modes that is not placed in the magnetic field of the stepper mechanism

摘要

Adjustment device for motor vehicle seats has a locking device with a locking element, which can lock output forces against a rotating housing. Device has an activation element (9) for switching a switching element (30), that meshes with locking elements (21, 22) of the locking device (2) when it is activated. Accordingly the locking elements are pushed or removed from a meshing region (200') of a housing (20) and the locking device switched to its ineffective state.
