Abstract
Official abstract text for this publication.
An electric actuator system for hospital and care beds comprising at least one linear actuator ( 9,48 ) for adjusting the lying surface of the bed. The actuator ( 9,48 ) used for adjusting the backrest section ( 6,57 ) of the bed comprises means for registering the force which it is exposed to. By comparing the registered forces to a zero value and/or a force interval, it can be determined whether the person occupying the bed is in the process of leaving the bed or has already left the bed. A connected alarm can thus notify the staff that the bed-bound person is in the process of leaving the bed.
