ABSTRACT:
A seat-bed assembly is provided including a pair of units in facing relation each including a seat and a back, the units being operable between a seat condition in which forward edge portions of the seats are spaced a substantial distance from each other with the backs projecting upwardly and rearwardly from rearward edge portions of the seat and a bed condition in which the seat sections are moved forwardly to position the forward edges thereof in contiguous relation and in which the backs are moved down behind the seats, the upper surfaces of the seats and backs being then in a common horizontal plane. An important feature is in the provision of an operating mechanism for each unit including pivotal arms pivotally connected to the back, first links pivotally connected between intermediate points of the arms and the rearward part of the seat and second links pivotally connected between intermediate points of the first links and the back. The distance between the axes of pivotal connections are such that the top edge portion of the back is moved in a substantially vertical path when the seat is moved between its rearward and forward seat and bed positions.
