The first nonpositive and positive element ( ), configured as a tensioning element, is firmly linked on the one side ( ) with a part ( ) that is mobile vis-a-vis the base ( ) and can be actuated on the other side ( ), with a variable and continuous pretension, via a first actuator ( ), while the second nonpositive and positive element ( ), configured as a relaxing element, is firmly linked on the one side ( ) with the base ( ) and can be actuated on the other side ( ), with a variable and continuous pretension, via a second actuator ( ′). The invention is characterized in that the tension force or relaxing force can be continuously modified during the tensioning or relaxing process.
