Abstract
A seat structure for a passenger seat, and a passenger seat. In one embodiment, the seat structure comprises a seat pan for mounting on a frame structure of the passenger seat in a manner such that the seat pan is moveable in forward and backward directions relative to the frame independently from movement of a seat back of the passenger seat; and biasing means for biasing the seat pan in a default position.
Claims20
A seat structure for a passenger seat, the seat structure comprising:
- a first seat pan for mounting to a frame structure of the passenger seat;
- and
- a second seat pan for disposing-above the first seat pan such that the second seat pan is moveable relative to the first seat pan in forward and backward directions with reference to the frame structure, the second seat pan being rigid,
- wherein the first seat pan or a guiding structure of the seat structure is configured for guiding a movement of the second seat pan on a curved trajectory along the forward and backward directions, and
- wherein the first and second seat pans have substantially matching curvatures along respective depths thereof, the curvatures extending across an entire width of the first and second pans, respectively.
