Patent ID: 7100926

Claim:
Roll stabilizer for a chassis of a motor vehicle, comprising an actuator ( 3 ), arranged between stabilizer halves ( 1 , 2 ) and rotating them relative to one another around a rotational axis, when necessary, the actuator ( 3 ) is provided with a failsafe device ( 34 ), to connect the two stabilizer halves ( 1 , 2 ) in a torque transferring manner upon activation, an actuator component ( 46 ) is connected in a torque transferring manner to one of the stabilizer halves ( 1 ) and another actuator component ( 45 ) is connected to the other of the stabilizer halves ( 2 ), with the failsafe device ( 34 ) being arranged effectively between the two actuator components ( 45 , 46 ), the failsafe device ( 34 ) is provided with a locking mechanism ( 34 a ), which, in a failsafe mode, locks the two actuator components ( 45 , 46 ) to one another in a torque transferring manner, wherein the locking mechanism ( 34 a ) is provided with a lock bolt ( 36 ), which, in a passive position, does not engage the two actuator components ( 45 , 46 ) and, in an active position, engages the two actuator components ( 45 , 46 ).
