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.
