Abstract
An adjustable bed system includes a pair of side rails transversely spaced, longitudinally aligned and arranged parallel to each other; and a pair of lifting assemblies attached respectively to the pair of side rails for operably adjusting positions of at least one part of a bed. Each lifting assembly comprises a back lifting arm and a leg lifting mechanism; a bracket; and a back lifting actuator and a leg lifting actuator received in the bracket. Each actuator includes an activation member and a motor member engaged with the activation member for driving the activation member. The activation member of the back lifting actuator is engaged with the back lifting arm for operably adjusting the back lifting arm at desired back positions. The activation member of the leg lifting actuator is engaged to the leg lifting mechanism for operably adjusting the leg lifting mechanism at desired leg positions.
