A motor vehicle with a lowerable roof construction, particularly a convertible sports car, has a roof part and a rear part as well as a forced control device for controlling the relative movement of the roof part with respect to the rear part. The forced control device has at least one control element which is connected in the region of the roof swivel axis in a rotationally fixed manner to the roof part and interacts with at least one further control element which is fixed to the body of the vehicle and is in the region of the rear swivel axis.

Motor vehicle with a lowerable roof construction

This invention relates to a locking mechanism for the locks of the rear doors of a motor vehicle with one locking device for each door lock acting against the unauthorized opening of the doors from the interior side of the doors, a so called child safety lock. Each locking device is assigned an electric-motor-driven control unit, the rotational direction of said control unit being reversible via a double pole changing switch (double throw switch) and said control unit being connected with it and being able to be remotely operated with respect to locking or unlocking of the lock by a switching element that can be operated from the front seats. The locking condition of the locking device is indicated by an optical display. To reduce manufacturing parts and expenses for the circuit controlling the optical display, this circuit is formed by parts of the circuit controlling the locking devices themselves. In certain embodiments the optical display is connected in series with a p-n-p transistor having its base and collector connected with respective grounded 'off' lines of the locking device control circuits.
