an airbag (14), inflated upon issuing of said tilting signal; said airbag (14) comprising one or more segment, each of said one or more segments projecting into a protrusion when inflated; and each of said protrusions projecting in a projected direction substantially perpendicular to and towards an imaginary line between two feet of said tripod (50);
a direction of said tilting being in a direction substantially in one of said projected directions, a directly inflated segment is that one of said plurality of segments projecting in said tilting direction, thereby enabling cushioning of a fall to the ground of said appliance due to said tilting; and
