Actuating device for actuated opening of a cover

Abstract:

An actuating device for opening and closing a cover in or on a vehicle includes a housing, a rotatable plunger, a spring that preloads the plunger into a discharge position, and an actuating sleeve into which the plunger can be introduced. At least one actuating groove extends helically around the longitudinal axis of the actuating sleeve and is formed on the inside of the sleeve. At least one actuating projection of the plunger engages into the actuating groove when the plunger is introduced into the actuating sleeve causing the plunger to rotate about its longitudinal axis during an axial relative movement between the actuating sleeve and the plunger. A blocking device blocks plunger movement into the discharge position to hold the plunger in a locked position. A spring element preloads the blocking device into a blocking position, and an actuator disengages the blocking device from the blocking position.
