1. An adjustable bed, comprising:
- a base frame;
a mattress frame including a head section and a lower section pivoted to said head section;
mounting means operatively connected to said base frame and said mattress frame for permitting said mattress frame to be moved between a high position and a low position relative to the base frame with the head section and lower section of the mattress frame lying in a generally common plane and for permitting said head section to pivot upwardly with respect to said lower section to define a seated position only when said mattress frame is in the low position; and
a single actuator pivotally connected to said base frame and having an extendable and retractable member directly connected to said head section of said mattress frame for lowering said mattress frame from the high position to the low position with said sections in a horizontal orientation and for pivoting said head section upwardly towards the seated position only when the mattress frame is in said low position.

Abstract
An adjustable bed includes a base frame and a mattress frame having a plurality of pivotally interconnected sections. A plurality of links are positioned between the base frame and the mattress frame. The mattress frame may be moved between a high position and a low position. A single linear actuator is connected to the mattress frame. The actuator is extendable and retractable to raise and lower the mattress frame with the mattress frame sections in a common plane. The actuator may also be retracted when the mattress frame is in the low position to articulate the mattress frame sections.

12. A high/low mechanism for an articulating bed of the type including a base and a mattress support having a back section pivoted to a leg section, said mechanism comprising:
-
an arm attachable to the back section; linkage means adapted to be connected to the base and the mattress support and permitting the support to be moved between high and low positions relative to the base with the back and leg sections lying in a common plane; an actuator bracket attachable to the base; and a linear actuator pivoted to said actuator bracket and having an extendable and retractable element, said element connected to said arm and wherein said arm and said linkage means are positionable and dimensioned so that when the element is in a fully retracted position the back section is angled to a seating position relative to said leg section and as the element extends towards an outer limit the back section is lowered to a flat position relative to said leg section and the mattress support is then raised to the high position with said sections flat. - View Dependent Claims (13, 14, 15, 16, 17)
