- the present invention relates to an aircraft seat structure, and more particularly to a seat structure that protects an occupant in the event of an impact.
- FAR Federal Aviation Regulations 23.562 stipulates the strength of the seat, but there is no provision for the aircraft structure including the seat. Aircraft are operated at high speed, and the impact speed is more than double that of automobiles and railway vehicles, and the required amount of impact absorption energy is more than four times. On the other hand, in aircraft, there is a strong demand for weight reduction and compactness compared to automobiles and railway vehicles, and it is difficult to secure an absorption stroke amount at the time of impact.
- Patent Document 1 a seat structure that effectively absorbs an impact with a small stroke amount and protects a passenger has been proposed.
- the technique described in Patent Document 1 is an example of such a technique.

- the moving means holds a front side of the occupant protection member so as to be rotatable about an axis substantially parallel to the left and right axis of the occupant and a rear side of the occupant protection member so as to be movable in the vertical direction of the body.
- a telescopic means may absorb shock during the contraction process.
- the occupant protection member may further include a vertical wall portion disposed at an end portion in the body width direction of the occupant protection member and an impact absorbing member disposed at a side portion of the body adjacent to the vertical wall portion.
- an airframe structure member connected and arranged on the lower side of the airframe of the occupant protection member, and a changing unit that changes the length of the airframe structure member in the vertical direction of the airframe may be further provided.
- the present invention since the occupant space including the seat is covered with the occupant protection member from the lower side of the fuselage, it is possible to secure the occupant protection space and securely protect the occupant at the time of landing impact in the event of a crash, etc. Become.
- a sufficient shock absorbing stroke can be secured even in a small space, and the impact on the occupant can be further reduced.
- the expansion and contraction means absorbs the impact during the contraction process, so that the collision energy at the time of the secondary collision can be absorbed to further protect the passenger.
- the impact applied to the airframe can be effectively absorbed by stably plastically deforming the impact absorbing member, thereby further occupant protection. Can be achieved.
- the shock absorption stroke can be effectively secured, and the impact on the occupant can be further reduced.

Alternatively, it may be branched to the wire 36b fixed by the fixing portion 42 on the upper outer wall surface of the upper girder.
- the wire 36 when the wire 36 is pulled by a collision load, first, the wire 36a is pulled inward, and the adhesive portion 35 is peeled in the same manner as described above to separate the upper girder 33 and the lower girder 34 from each other. . Further, when the tension increases, the wire 36b is not loosened, and the upper girder 33 is pulled downward to compress the length of the main wing main girder 6 in the vertical direction.
- an inflatable bag made of a rubber material or the like is disposed in the bonding portion 35, and in the event of a collision, the bag is inflated to peel off the bonding portion, and then a hydraulic actuator or the like is installed. It is good to pull down the upper girder 33 using it.

- a small amount of explosives is arranged at several places in the bonding portion 35, and the bonding portion 35 is peeled off by performing a small explosion similar to the operation of the airbag 11. It is preferable to divide the entire upper girder 33 of the body part by separating the peripheral position intersecting the body side surface of the upper girder 33 by the same method. In this case, there is no particular need for a mechanism for pushing down the divided upper girder 33 downward, and when the survival tab 1 is pushed down, the upper girder 33 is pushed down without resistance, and the survival tab 1 An increase in the downward movement stroke can be realized.
- Each of the above embodiments is an example, and can be appropriately changed and combined. It is also possible to use a combination of a mechanical type, a hydraulic type, and an electric type.
