The pod comprises a central mast ( 1, 8 ), a support section ( 9 ) of which bears ends of arms ( 30 ) pivotally mounted so that respective opposed free sections ( 32 ) are, in a position folded back against the mast ( 1, 8 ), maintained by a removable locking device comprising an axially movable crown member ( 10 ) for radially locking the arms ( 30 ), the crown member ( 10 ) being held in locking position through a hysteresis effect in which the crown member ( 10 ) can be driven, through the expansion of a loaded spring ( 20 ), in a movement of recoil from its locking condition, only after additional loading of the spring ( 20 ) by an external force in order to release a mobile stop ( 21 ), for inhibiting the action of the spring ( 20 ), held in precarious anti-recoil stop equilibrium by the crown member ( 10 ). |
