Abstract: Adjustable article of furniture comprising at least one adjustable element and furnished with an actuator system comprising at least one electrically driven linear actuator with an electrical motor and an electrical controller with an operation device, wherein the system in equipped with a battery pack for operating the system during mobile situations, where a mains supply is not readily available. The battery pack is equipped with a frontend, which allows for the battery pack to be retrofitted on existing actuator systems, without compromising the functionality of the actuator system in connection with charging of the battery. Moreover, the frontend is adapted to facilitate continued viewing of remaining power on the battery pack even though the technology of the battery pack is replaced, e.g. from lead battery to lithium ion battery.

Abstract: Bed, comprising a lower frame (1) and an upper frame (2) with a supporting surface for a mattress, and where the upper frame (2) is connected to the lower frame (1) so that the upper frame can be raised and lowered in proportion to the lower frame by means of one or more adjusting means (5, 6) driven by an electric motor. In order to prevent squeezing between the upper and lower frame when the upper frame is lowered, the bed is provided with anti squeezing means. These comprise a light source and a receiver positioned in a corner of the lower frame. The light source sends a light beam which follows the lower frame all the way around and runs just above the top side of the lower frame. When the light beam is interrupted the control unit reacts by cutting off the current for the motors.
