Abstract
An improved seat-bed assembly providing a seat unit and a back frame support, both of which are interconnected by a controlled linkage that, coupled with a guided movement of the back frame support, will convert the assembly from a seat form to a full length bed. Pivotal withdrawal of the seat unit from the assembly will, through a drag link arrangement, pivot the back frame support through a guided path into a bed forming position with the now extended seat unit.

In an article of furniture, convertible from a chair to a bed, including:
- (a) a frame providing spaced-apart side arm frames;
- (b) a back frame positioned between said side arm frames and having a controlled limited movement therebetween;
- (c) a seat unit pivotally connected about a horizontal axis between said side arm frames and adapted for distended pivotal movement relative thereto;
- (d) means for guiding and controlling limited movement of said back frame between said side arm frames;
- and
