Then, after the air in the storage bag 25 is sucked from the check valve 25A provided in the storage bag 25 and the protective device 10 is packaged in a compressed state as shown in FIG. It is housed and packed in an outer bag (not shown). Instead of wrapping the storage bag 25 with an outer bag (not shown), the storage bag 25 may be bound in a cross shape with a string or a band. The storage bag 25 is also enclosed with an earplug (not shown) made of low-resilience foamed resin.

  The description regarding the structure of the protective device 10 of this embodiment is above. Next, the function and effect of the protective device 10 will be described. The protective equipment 10 is handed over from the cabin attendant to the passenger at the boarding gate of the aircraft in accordance with each physique. When the passenger gets to the passenger seat, the protective device 10 is placed in the back pocket of the front passenger seat, in the passenger compartment under the passenger seat, or in the upper trunk room.

  When no abnormality has occurred in the aircraft, the protective equipment 10 left in each passenger seat after the passenger leaves the aircraft is collected and used again. When an abnormality occurs in the aircraft, each passenger temporarily removes the seat belt, leaves the passenger seat, takes out the protective device 10 from the storage bag 25, and wears it as shown in FIG. Then, as shown in FIG. 5B, the first to third belts 21, 22, 23 (hereinafter simply referred to as "belts 21, 22, 23") are appropriately tightened and seated on the passenger seat, After the seat belt is attached, it is bent forward as shown in FIG. At this time, it is preferable that both arms are stored in the protective device 10. Moreover, it is preferable to endure the noise at the time of a fall by putting on an earplug.

  In this state, each passenger is covered entirely above the thigh by the protective device 10 made of the low-rebound bag-shaped cushion material 11, so that, for example, the aircraft fluctuates and scatters toward the passenger seat. Even if an object flies and collides with a passenger, the impact is alleviated by the protective device 10, and the life of the passenger is protected.

  In addition, even if the aircraft crashes and the passenger seat is damaged, and the human body is thrown out of the passenger seat and hit against the wall in the aircraft or the broken passenger seat, the impact at that time is caused by the protective equipment 10 Damage to the human body in the protective device 10 is alleviated. In particular, since the bag-shaped cushion material 11 of the protective device 10 has a thickened constricted portion 14 surrounding the neck of the human body, the neck is protected thickly, and the life of the user of the protective device 10 can be protected.

  Moreover, since the thigh, the waist, and the torso are squeezed by the belts 21, 22, and 23, the protective device 10 prevents the protective device 10 from being inadvertently detached and the protective device 10. The space inside can be reduced, and the human body can be effectively protected from impact. Furthermore, since the protective device 10 is covered with the cushion cover 20, the bag-shaped cushion material 11 is not easily damaged even if the protrusion collides with the protective device 10 for a plurality of times. Moreover, since the cushion cover 20 is nonflammable or flame retardant, it also serves to protect the human body from flames when a fire occurs in the machine. It should be noted that after the aircraft stops, the protective equipment 10 may be removed or attached to the emergency exit.

  As described above, according to the protective device 10 of the present embodiment, it is possible to protect the human body from an aircraft accident thicker than before. In addition, since the elasticity of the protective device 10 is lowered when the protective device 10 is held in a compressed state for a long time in the storage bag 25, it is preferable to periodically replace the protective device 10 mounted on the aircraft with a new one.
