Abstract
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.
