Abstract
An adjustment drive apparatus particularly for motor vehicles having coaxial rotatably supported driving and driven members with a helical spring which is braced against the inner circumferential surface of a hollow cylindrical element coaxial with these members operating to effect drive transmission therebetween. One of the members has a first claw or driver connection member rigidly affixed thereto, the claw member pressing against one of the ends of the helical spring to effect an extension or enlargement of the spring when relative rotation occurs between the spring and the claw member. The hollow cylindrical element within which the helical spring is located is affixed for rotation with the other of the driving and driven members. An auxiliary driving member is provided which, when activated, will cause the spring to be disengaged so that the driven member may be rotated through the auxiliary driving member.
