Claim 7:
8. An adjustable bed base comprising:
a generally rectangular stationary frame having opposed side rails, a head rail, a foot rail and a middle rail, each of the side rails having a C-shaped cross-section defining a channel;
a subframe secured to the stationary frame, the subframe having opposed side members, a head member, a foot member and a cross member extending between the opposed side members,
a front pusher assembly comprising front lift arms and a front push member extending between the front lift arms, each of the front lift arms being pivotally secured to one of the side members of the subframe;
a rear pusher assembly comprising rear lift arms and a rear push member extending between the rear lift arms, each of the rear lift arms being pivotally secured to one of the side members of the subframe;
rotatable wheels secured to lower ends of the front and rear lift arms, the rotatable wheels being movable inside the channels of the side rails of the stationary frame;
lift arm supports for limiting movement of one of the front and rear lift arms, each of the lift arm supports being pivotally secured to one of the lift arms and pivotally secured to a corner bracket secured to the stationary frame;
an articulated deck comprising a head deck board, a seat deck board, a leg deck board and a foot deck board hinged together, the seat deck board being secured to the subframe;
a head brace secured to the head deck board;
a leg brace secured to the leg deck board;
a front primary linear actuator having a first end pivotally secured to a first mounting bracket secured to the middle rail of the stationary frame and a second end pivotally secured to a mounting bracket secured to the front pusher assembly, wherein the front pusher assembly is moved forwardly when the front primary linear actuator is extended, thereby raising a front portion of the subframe;
a rear primary linear actuator having a first end pivotally secured to a second mounting bracket secured to the middle rail of the stationary frame and a second end secured to a mounting bracket secured to the rear pusher assembly, wherein the rear primary linear actuator moves the rear pusher assembly rearwardly when the rear primary linear actuator is extended, thereby raising a rear portion of the subframe;
a front secondary linear actuator for inclining the head deck board, the front secondary linear actuator having a first end pivotally secured to a mounting bracket secured to the cross member of the subframe and a second end pivotally secured to the head brace; and
a rear secondary linear actuator for moving the leg and foot deck boards, the rear secondary linear actuator having a first end pivotally secured to a mounting bracket secured to the rear member of the subframe and a second end pivotally secured to the leg brace.
