Locking system for the doors of automotive vehicles
First Claim
1. In an automotive vehicle including a body and doors fitted to the body to enclose a passenger compartment within the body, each door having a single latch, which will engage a keeper on the body as the door is closed to retain the door in a closed position, and an exterior handle, which is connected to the latch such that, when the handle is operated, the latch will release the keeper, the latch being shiftable between a locked condition, wherein operation of the handle will not release it from its keeper, and an unlocked condition wherein the operation of the handle will release it from the keeper, an electrically operated actuator in at least one of the doors where it is connected to the single latch on that door for changing the latch between its locked and its unlocked condition when energized, and a battery housed in the body for supplying the electrical energy for operating the actuator, the improvement comprising:
- a remote switch located on the body remote from the passenger compartment and connected between the actuator and the battery, the remote switch being capable of placing the actuator across the battery when operated such that the actuator causes the single latch on said one door to assume its unlocked condition.

Abstract
An automotive vehicle has a body provided with a passenger compartment and a luggage compartment. Doors, which close the passenger compartment, carry latches which engage the body to secure those doors. While the doors have exterior handles which are connected to the latches to release the latches, at least when the latches are set to an unlocked condition, each latch may be shifted to a locked condition in which the exterior handle for its door will not release it. Each door also carries an electrical actuator which is coupled to the latch of the door to shift that latch between its locked and unlocked conditions. Two of the doors carry switches which are accessible from the passenger compartment and when operated will cause electrical actuator to shift the latches in unison to their locked or unlocked conditions, depending on the manner in which the switch is manipulated. In addition, the luggage compartment contains a remote switch which is connected to all of the actuators and when operated causes the actuators to shift all latches to their unlocked condition.

8. An automotive vehicle comprising:
- a body having a passenger compartment and a luggage compartment;
doors attached to the body and normally being in a closed position in which they close the passenger compartment;
latch means on each door for engaging the body as the door is closed to retain the door in its closed position, but being releaseable from the body to enable the door to open, each latch means being shiftable between locked and unlocked conditions;
a handle carried on each door and being movable with respect to its door, the handle for each door being connected to the latch means for the door such that the handle, when moved, will release the latch means if the latch means is in its unlocked condition, but not if it is in its locked condition;
an electrical battery housed in the body;
a key-operated lock on at least one of the doors where it is connected to the latch means for that door for causing the latch means to assume its locked or unlocked condition when a key within the lock is manipulated;
an electrical actuator in each door and connected to the latch means for changing the latch means from its locked to its unlocked condition and vice-versa when placed across the battery;
a door switch located at at least one of the doors and being electrically interposed between the battery and all of the actuators for, when operated, causing the actuators PG,18 to change the latch means in unison between their locked and unlocked conditions; and
a remote switch located in the luggage compartment and being electrically interposed between the battery and the actuators for, when operated, causing the actuators to assume in unison their unlocked condition. - View Dependent Claims (9, 10)
