First Claim
1. An aircraft seat convertible to a bed comprising:
- a seat having;
a squab and a backrest, both being movable anda mechanism for moving the squab and the backrest, the mechanism having;
a seat chassis, via which the seat can be fixed to a floor,a first linear runner beam mounted on the seat chassis,a seat frame sub-frame bearingly mounted on the first linear runner beam,linear drive means for extending and retracting the sub-frame on the first linear runner beam with respect to the seat chassis between a retracted position and an extended bed position,a pan for the squab pivotally mounted on the sub-frame,pan angle drive means for pivoting the pan between a back dropped TTL position and a bed position,a support for the back rest hinged to the pan andback drive means for moving the back rest support between a back up TTL position and a bed position.

Abstract
An aircraft seat has a chassis (21), fixed to a pallet which is fixed to the floor of the aircraft. The chassis has two load bearing sides (23) and opposite ends (24, 25). Fixed along the top edge of the sides (23) and facing outwards are pins (26) supporting bearing wheels (27). These on each side engage with a rectangular S form interconnection beam (28) having an inside groove (29) for receiving these wheels. On the outside, the beam has another groove (30) receiving similar wheels (31), on pins (32) fixed to the inside of side plates (41) of a sub-frame (42), these side plates being interconnected by front and rear beams (43, 44). Thus the sub-frame can move back and forth, with the wheels acting as rolling element bearings. The beams move half the distance of the sub-frame, in analogous manner to the bearing of filing cabinet drawers.
