Theory of Operation
Introduction
The main components and controls for the bed are discussed in this section.
Base
The base supports the entire bed, included in this module are the casters, the
optional brake and steer assembly, and the lift arms.
Intermediate Frame
The intermediate frame connects the base to the sleep deck, and provides
attachment points for the drive motors that provide the motion of the different
bed sections.
Articulating Sleep Deck
The articulating sleep deck contains the head, seat, knee, and foot sections.
These sections, except for the seat section, articulate in a manner that changes
the angular orientation of the section to the intermediate frame.
Siderails
There are two siderails on each side of the bed. The siderails raise and lower.
When lowered, the siderails tuck below the sleep deck.
Motion Control
The motion control for the electric bed consists of linear actuators, siderail
controls, foot end controls, and electronics that provide the motion of the sleep
deck. For the manual bed, the motion control is made up of cranks and other
mechanisms.
