A legrest for an aircraft passenger seat, comprising a device, wherein: the device has a housing; the housing has a first and a second housing half; the two housing halves are pivotally connected to one another; the housing is designed such that a life jacket for an aircraft passenger can be stowed therein; the device is provided on a main structure of the legrest; the first housing half is spring-loaded with respect to the second housing half by the spring force of a spring device of the device, such that the first housing half can be moved from an open position relative to the second housing half towards a closed position relative to the second housing half.

A latch assembly may comprise a keeper and a lever. The keeper may include a keeper channel defined at least partially by a first channel surface and a second channel surface. The lever may be configured to rotate relative to the keeper and between an engaged state and a released state. The lever may comprise a shaft and a lever protrusion extending from the shaft. The lever protrusion may be defined at least partially by a proximal surface and a distal surface. The keeper channel may be configured to receive the lever protrusion. In the engaged state, the proximal surface of the lever may contact the second channel surface of the keeper and the first channel surface of the keeper may be spaced apart from the lever protrusion.
