Abstract
Abstract A central lock system for a motor vehicle having a trunk door and a gas-filler door, has respective latches at the trunk and gas-filler doors movable between locked and unlocked positions corresponding to locked and unlocked conditions of the respective doors and an actuator adjacent the trunk latch having a single output member displaceable between an actuated and an unactuated position and a motor connected to the member for displacing same between the respective positions. Respective trunk and gas-filler links are connected to the respective latches and are both connected to the member. A controller is connected to the motor for actuating same and thereby simultaneously moving the trunk and gas-filler latches between the locked and unlocked positions.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
157 words
In a motor vehicle having a trunk door and a gas-filler door, a central lock system comprising: respective latches at the trunk and gas-filler doors movable between locked and unlocked positions corresponding to locked and unlocked conditions of the respective doors; an actuator adjacent the trunk latch having a single output member displaceable between an actuated and an unactuated position, and a motor connected to the member for displacing same between the respective positions; means including respective trunk and gas-filler links connected to the respective latches and both connected to the member for simultaneously displacing both the trunk and gas-filler latches into the respective unlocked conditions on displacement of the output member into the actuated position and into the respective locked conditions on displacement of the output member into the unactuated position; and control means connected to the motor for actuating same and thereby simultaneously moving the trunk and gas-filler latches between the locked and unlocked positions.
Claim 2
Dependent Claim
157 words
In a motor vehicle having a trunk door and a gas-filler door, a central lock system comprising: respective latches at the trunk and gas-filler doors movable between locked and unlocked positions corresponding to locked and unlocked conditions of the respective doors; an actuator adjacent the trunk latch having a single output member displaceable between an actuated and an unactuated position, and a motor connected to the member for displacing same between the respective positions; means including respective trunk and gas-filler links connected to the respective latches and both connected to the member for simultaneously displacing both the trunk and gas-filler latches into the respective unlocked conditions on displacement of the output member into the actuated position and into the respective locked conditions on displacement of the output member into the unactuated position; and control means connected to the motor for actuating same and thereby simultaneously moving the trunk and gas-filler latches between the locked and unlocked positions.
Claim 3
Dependent Claim
27 words
The motor-vehicle central-lock system defined in claim 1 wherein the output member has two ends each connected via a respective one of the links to the latches.
Claim 4
Dependent Claim
17 words
