Abstract
An articulated bed assembly includes a stationary frame structure to which an upper body support section and a lower body support section are pivotably mounted for movement between raised and lowered positions. An actuator arrangement includes an actuator member which is adapted for extension and retraction in response to operation of an operating arrangement such as a drive motor. The actuator member is interconnected with the upper body support section through a drive member for raising and lowering the upper body support section in response to extension and retraction of the actuator member. An operating mechanism is interconnected between the actuator member and the lower body support section for lifting and lowering the lower body support section in response to extension and retraction of the actuator member. The operating mechanism includes a linkage arrangement defining a first link pivotably mounted to the stationary frame assembly and a second link pivotably mounted to the actuator member. The first and second links are pivotably interconnected together, and a lift arm is interconnected between one of the links and the lower body support section. The first and second link …
