Abstract
Abstract This control comprises a pivotable actuating lever 6 whose ends forms a lug 20 for actuating the electric circuit of the latch and a heel 18 cooperative with a linkage for mechanically controlling the latch. A barrel 14 actuated by a key carries a locking cam 32 which, on one hand, actuates a bistable relay of the general electric supply circuit, and, on the other hand, forms an abutment 34 for stopping the pivoting of the lever 6. This cam may be shifted by means of the key so as to retract the abutment 34 and enable the lever to pivot until the linkage is brought into action for mechanically opening the latch.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
275 words
An exterior control structure in combination with a vehicle door, a latch for the door, electric shifting means combined with the latch for selectively opening and closing the latch, an electric circuit including switching means for electrically controlling the electric shifting means, a linkage for mechanically opening the latch in the event of breakdown of said electric circuit or electric shifting means, said control structure comprising an actuating element mounted on the door to be movable between a first position and a second position, means for resiliently returning the actuating element to said first position for closing the latch, and a rotatable barrel actuatable by a key and having an inner end, means for locking and preventing operation of the latch and cooperative with said inner end of the barrel, the actuating element having an end which defines a lug cooperative with said switching means of the electric circuit for controlling said electric shifting means for the latch and a heel cooperative with the linkage, the means for locking the latch comprising a locking cam which is fixed to the barrel and carries an abutment cooperative with the heel of the actuating element, said abutment being movable with said cam by said key between a first position in which the abutment lies in a path of movement of the heel and thereby prevents the actuating element from moving to said second position of the actuating element and a second position in which the abutment is clear of said path of movement and allows the actuating element to move to said second position of the actuating element and open the latch by means of said linkage.
Claim 2
Dependent Claim
275 words
An exterior control structure in combination with a vehicle door, a latch for the door, electric shifting means combined with the latch for selectively opening and closing the latch, an electric circuit including switching means for electrically controlling the electric shifting means, a linkage for mechanically opening the latch in the event of breakdown of said electric circuit or electric shifting means, said control structure comprising an actuating element mounted on the door to be movable between a first position and a second position, means for resiliently returning the actuating element to said first position for closing the latch, and a rotatable barrel actuatable by a key and having an inner end, means for locking and preventing operation of the latch and cooperative with said inner end of the barrel, the actuating element having an end which defines a lug cooperative with said switching means of the electric circuit for controlling said electric shifting means for the latch and a heel cooperative with the linkage, the means for locking the latch comprising a locking cam which is fixed to the barrel and carries an abutment cooperative with the heel of the actuating element, said abutment being movable with said cam by said key between a first position in which the abutment lies in a path of movement of the heel and thereby prevents the actuating element from moving to said second position of the actuating element and a second position in which the abutment is clear of said path of movement and allows the actuating element to move to said second position of the actuating element and open the latch by means of said linkage.
Claim 3
Dependent Claim
24 words
A control structure according to claim 1, comprising resiliently yieldable means for resiliently biasing the locking cam to said first position of the cam.
Claim 4
Dependent Claim
63 words
A control structure according to claim 1, comprising a source of power for the electric circuit, a bistable relay for selectively opening and closing the electric circuit, the cam comprising a lateral boss which is remote from the abutment, a switch of said switching means being cooperative with the bistable relay for actuating the bistable relay, said boss being cooperative with said switch.
Claim 5
Dependent Claim
53 words
A control structure according to claim 3, wherein the abutment and the boss are so placed on the cam as to come into action alternately, the rotation of the cam by the key moving the abutment away from the heel of the element when the boss acts on said switch of the relay.
Claim 6
Dependent Claim
57 words
A control structure according to claim 1, wherein the linkage is connected to an ear of the heel and includes a lost-motion travel rendering the linkage inoperative during movement of the actuating element between said first and second positions thereof, but operative to open the latch when the actuating element is shifted beyond said second position thereof.
Claim 7
Dependent Claim
44 words
A control structure according to claim 1, wherein said switching means comprise a switch, the lug of the actuating element being cooperative with the switch for depressing and opening the switch in said first position of the actuating element corresponding to a closed latch.
