SPRING-OPERATED BACK-UP/FAIL-SAFE MODULE FOR ACTIVE GRILLE SHUTTER SYSTEMS

摘要

A fail safe module for an active grille having two or more vanes movable between an open position and a closed position. In the event of failure of an electrically driven actuator, a fail safe module connected between a driven vane of the two or more vanes and the electrically driven actuator moves the vanes to a fail-safe position. The fail safe module has a locked and unlocked position when the fail safe module is in the locked position the fail safe module, the electrically driven actuator and the two or more vanes move together in response to the power provided by the electrically driven actuator. When the fail safe module is in the unlocked position, the fail safe module disengages the two or more vanes from the electrically driven actuator and moves the two or more vanes to the fail-safe position.
