Abstract
A patient support system comprises a patient support apparatus for patients. The patient support apparatus comprises a support structure and a patient support surface supported by the support structure. The patient support apparatus also comprises movable members. One or more rotary actuators are coupled to the movable members. The rotary actuator comprises a gear assembly with a cycloidal drive arranged to drive movement of the movable member. The gear assembly also restricts back drive torque from backdriving the movable member.
Claims21
A patient support apparatus comprising:
- a patient support surface;
- a first member and a movable member, said movable member movable relative to said first member;
- and
