Abstract
A crashworthy bench (1) for an aircraft having a cabin that includes a floor (51), a ceiling (52), and substantially vertical partitions. Said bench (1) comprises a frame (2), at least one seat for a passenger, with each seat comprising a seat, a back, a retaining system (7) for retaining said passenger, and at least one energy absorber device (20). Said frame (2) is fastened to the inside of said cabin via one low connection point (8) for each seat and via at least one high connection point (9) for said bench (1). Two low connecting rods (11) and one leg (12) connect the frame (2) to each low connection point (8) on said floor (51). Two high connecting rods (15) connect the frame (2) to the high connection points (9) on said ceiling (52) or on a vertical partition of the cabin of the aircraft.
Claims20
A crashworthy bench for an aircraft having a cabin including at least a floor and walls of the cabin, the walls of the cabin including at least a ceiling and a plurality of substantially vertical partitions, the bench comprising:
- a frame;
- at least one seat for a passenger, each seat comprising a seat proper, a back, and a retaining system for retaining the passenger, all fastened to the frame;
- and
- at least one energy absorber device for the at least one seat;
- wherein the frame is suitable for being fastened to the inside of the cabin via a single low connection point on the floor for each seat via two low connecting rods and one leg for each seat, the low connecting rods mechanically connected to the frame at a front region of the seat proper and the leg being mechanically connected to the frame, the low connecting rods extending inwardly towards one another from the frame to the low connection point, and by at least one high connection point for the bench on at least one of the walls of the cabin via two high connecting rods, the high connecting rods being fastened to the at least one high connection point and being mechanically connected to the frame;
- and
- wherein the energy absorber device is mechanically associated at a first end with the leg and at a second end with the frame.
A crashworthy bench for an aircraft having a cabin including at least a floor and walls of the cabin, the walls of the cabin including at least a ceiling and a plurality of substantially vertical partitions, the bench comprising:
- a frame;
- at least one passenger seat comprising a seat proper, a back, and a retaining system for retaining a passenger, each of the at least one seat being fastened to the frame;
- at least one energy absorber device for each of the at least one seat;
- a first low connecting rod for each of the at least one seat, the first low connecting rod having a first rod proximal end and a first rod distal end, the first rod proximal end being coupled to the frame;
- a second low connecting rod for each of the at least one seat, the second low connecting rod having a second rod proximal end and a second rod distal end, the second rod proximal end being coupled to the frame and spaced from the first rod proximal end;
- a leg for each of the at least one seat, the leg having a leg proximal end and a leg distal end, the leg proximal end being coupled to the frame, wherein the leg distal end, first rod distal end, and second rod distal end are directly adjacent to one another and fastenable to the inside of the cabin at a single low connection point on the floor, the first and second low connecting rods extending inwardly towards one another and converging from the frame to the single low connection point;
- and
- two high connecting rods, each high connecting rod being coupled to the frame and being fastenable to a high connection point.
A helicopter comprising:
- a cabin with a floor and walls, the floor including a low connection point, the walls including a ceiling, a plurality of substantially vertical partitions, and at least one high connection point;
- a frame;
- at least one passenger seat comprising a seat proper, a back, and a retaining system for retaining a passenger, the seat proper having a front region and a rear zone, the back connected to the seat proper at the rear zone, each of the at least one seat being fastened to the frame at the rear zone;
- at least one energy absorber device for each of the at least one seat;
- a leg for each of the at least one seat, the leg extending between and coupling the frame and the low connection point of the floor, the leg associated with the frame at the rear zone;
- a first low connecting rod for each of the at least one seat, the first low connecting rod extending between and coupling the front region of the seat and the low connection point of the floor through a first ball joint at a low connection point of the leg;
- a second low connecting rod for each of the at least one seat, the second low connecting rod being spaced from the first low connecting rod at the front region of the seat, the first and second low connecting rods extending inwardly towards one another and converging at the low connection point of the leg,
- the second low connecting rod extending between and coupling the front region of the seat and the low connection point of the floor through a second ball joint at the low connecting point of the leg;
- a first high connecting rod coupling the frame and a respective one of the at least one high connection point;
- and
- a second high connecting rod coupling the frame and a respective one of the at least one high connection point.
