Claims10
A spring support comprising:
- a housing;
- an actuator in said housing, said actuator comprising a stator which is fixed with respect to said housing and a rotor which is operable to rotate in said housing, said rotor being arranged radially outside of said stator and having an outer side with a force introducing profile;
- a force transmitting element which moves axially in response to rotation of said rotor, said force transmitting element having an inner side with a mating profile which cooperates with said force introducing profile to convert rotational movement to axial movement;
- a torsional locking element which prevents rotational movement of said force transmitting element with respect to said housing;
- and
- a spring plate fixed to said force transmitting element.
