Vehicle door type central locking system - has electric motors moving locking rods via crank and controlling reversing switches

摘要

Electric motors controlled by a bolting rod operated either by hand or key, are used in conjunction with the central locking device, as applied to vehicle doors. The motors (M) act on a crank drive via a reduction gear unit, to move bolting rods (R2) directly. They also mechanically control reversing switches (S21, S22), separating the potential drives after exactly one turn, to stop the motors, and short-circuiting them. This can be equally well operated electrically or manually.
