COUPLING DEVICE FOR PASSENGER SEATS

摘要

Described are passenger seats with a seat pan (12) releasably coupled to a seat frame (14) via at least one coupling device (20), which includes a ramp (22) mounted on a lower surface (36) of the seat pan (12) and a latch (42) pivotally coupled to an open end of the ramp (22). The latch (42) includes a flap configured to substantially cover the open end of the ramp (22) when the latch (42) is in a closed position, and a handle (48) that is accessible from an upper surface of the seat pan (12) via an aperture (50) in the seat pan (12). The coupling device also includes a spring (44) configured to position the latch (42) in the closed position until a force is applied to the handle (48) to rotate the latch (42) to an open position.
