Abstract
Disclosed is a modular seat for aircraft. The system has a frame that is able to be interconnected with other frames laterally. Since each lateral frame has the same pivot points (when viewed from the side), the linked seats rotate together. The seats also include buckle lugs which enable a particular seat to be used on either side of the aircraft.
Claims12
An aircraft chair system comprising:
- a first seat frame having (i) a stationary base configured to be securable to an aircraft floor, (ii) a seat portion supported by the stationary base, and (iii) a back portion linked to the seat portion;
- the seat portion being translatable forward and the back portion being rotated down to form a bed resting surface;
- an upper portion of the seat back having an upper pair of laterally opposed seat-back beams interconnected by at least one transversely-extending member;
- a lower portion of the seat back including a lower pair of laterally opposed seat-back beams interconnected by at least one other transversely-extending member, a lower portion of each of the lower beams being pivotally connected to a rear portion of the translatable seat portion;
- a first pair of laterally opposed arms together presenting:
- (i) a first pivot point at a back upper fixed point on the stationary base;
- (ii) a second pivot point near a middle area of each lower beam;
- and (iii) a third pivot point at a lower portion of the upper beams;
- and
- a second pair of laterally opposed arms creating a lower pivot point at an upper portion of each of the lower beam members, and an upper pivot point on the upper beam at a location above the third pivot point created by the first pair of laterally opposed arms.
7 more elements
A chair system for aircraft, the system comprising:
- a plurality of modular seats, the plurality including one seat frame configured to link to another adjacent seat frame, the one and another seat frames moving together between a first mode and a second mode;
- the first mode presenting both frames to support an upright seating mode;
- the second mode establishing a substantially horizontal upper surface for supporting a bed;
- each of the plurality of seats including seat platform and seat back portions;
- each of the seat platform portions being configured to translate forward in transitioning from the first mode to the second mode;
- each of the seat back portions comprising an upper beam and a lower beam, the upper beam, during a transition from a first mode to a second mode, translating forward while rotating backward;
- and
- the lower beam being concealed when the system is in the second mode.

A seat system for aircraft, the system comprising:
- a stationary seat base configured to be attached on an aircraft fuselage floor, the seat base including lateral supporting frame members on each side of the stationary seat base;
- a forwardly-translatable seat frame portion configured to support a seat cushion;
- collapsible upper and lower seat back frame portions, the upper seat back frame portion configured to support a back cushion;
- and
- lug sets on an upper back edge of the stationary seat base, the lug sets enabling seat belts to extend through between the seat and back cushions when the seat is in a seating mode, and then concealed underneath the cushions between the lateral supporting members of the seat base when the seat is in a bed mode.
