Türschloß für ein Kraftfahrzeug

摘要

A control element (10) circuited (14) parallel to the central locking element adjuster (5) de-activates the child lock whenever the central locking system opens. A re-set spring (15) with fitted time dealy (11) reactivates the child lock after a pre-set interval. The control element comprises a pneumatic cylinder in the central locking circuit (14), using the spring (15) to re-set the cylinder piston. The time delay is in the form of a choke (11) allocated to the cylinder piston space (16) and the choke in turn is tied in with the cylinder (10) control feed line (12). Once back-seat passenger has blocked out the activation setting by the linked levers, the cylinder also de-activates the child lock to free the door, with the cylinder piston forced outwards accordingly. The spring (15) forces the piston (9) back in under control of the choke (11) and in so doing operates the child lock levers and thus re-activates the child lock. The lock function delay can be set to requirement.
