DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below with reference to the drawings.
[0007]
1 and 2 show the relationship between the in-flight pilot M and the seat 1 in a normal flight state. In the figure, the seat 1 is a seat body 3 and L as a whole for seating the pilot M on the seat. It consists of a character-shaped seat 2. The seat body 3 includes a horizontal portion 3a and a vertical portion 3b, and a cover drive mechanism 4 is provided on both sides thereof. In the present embodiment, cover members 6a and 6b having substantially triangular shapes in four side views are provided. , 6c and 6d are pivotally attached. The seat portion 2 includes a vertical seat portion 2a for supporting the back of the pilot M and a horizontal seat portion 2b for supporting the thigh, and the head portion H of the pilot M is above the vertical seat portion 2a. A headrest 5 is provided for supporting.
[0008]
According to the embodiment of the present invention, the pair of semicircular arc-shaped first airbags 9 and 9 are mounted on the vertical seat 2a around the neck of the pilot M, and the vertical seats in the vicinity of both upper arms. Second airbags 8 and 8 are attached to the portion 2a. Further, third airbags 7 and 7 are attached to the horizontal seat 2b in the vicinity of both thighs, and further below this, between the horizontal seat 2b of the seat 2 and the lower surface of the thigh. Four airbags 12 and 12 are disposed. Reference numerals 7a, 8a, 9a, and 12a denote gas generators that actuate (inflate) the airbags 7, 8, 9, and 12 described above.
[0009]
FIG. 3 shows a state in which the cover 6 is driven and the above-described airbags 7, 8, 9, 12 are operated. Along with this, high-pressure drive gas lines for the airbags 7, 8, 9, 12 are also shown. The escape drive handle 20 is provided at the center of both legs of the pilot M, and is lifted upward with both hands h or one hand h.
[0010]
At the time of emergency escape, the drive handle 20 is pulled up by the pilot M's hand h. As a result, the explosive 21 is ignited, passes through the gas lines 22 and 23, operates the gas generator 24, passes through the gas lines 27 and 28, and the gas generators 7a and 8a of the airbags 7, 8, 9, and 12 described above. , 9a, 12a are supplied with high-pressure combustion gas. As a result, in FIG. 3, as indicated by the dotted lines, the airbags 7, 8, 9, 12 are rapidly inflated, and the head H and neck of the pilot M are held against the seat 1 by the airbags 9, 9. Furthermore, both upper arms are in a state of being pinched by the airbags 8 and 8 (as indicated by dotted lines in FIG. 2). Both thighs are similarly clamped by the airbags 7, 7, and the thigh is lifted upward from the horizontal seat 2 b of the seat 2 by the airbag 12. In this state, the time delay initiator 25 is activated to drive the drive shaft 4 from the gas supply line 26, thereby driving the pieces 6a, 6b, 6c, 6d of the cover 6 in the counterclockwise direction in FIG. The lower surface of the first cover piece 6a is locked by the edge 3aa of the horizontal portion 3a of the seat 3 and takes the position shown in the figure, and the second, third, and fourth cover pieces 6b, 6c, and 6d are sequentially provided. The closed position as shown is taken. At this time, the body of the pilot M is in a posture in which the cover pieces 6a, 6b, 6c, and 6d do not interfere with each other by the airbags 7, 8, 9, and 12, so that the closed position can be safely taken.
[0011]
Further, as shown in the figure, high pressure gases g1 and g2 are ejected from the horizontal portion 3a and the vertical portion 3b of the seat 1 through the nozzles at the same time as or after the closing operation of the cover 6, so that an appropriate escape posture is obtained. I'm letting you. Although not shown, the jet gases g1 and g2 are provided at two locations on the bottom and back of the seat 1, and gas jet nozzles are provided on both sides of the seat (not shown). (Although not always necessary) I have a proper escape posture. At least one rocket for generating the high-pressure gas is provided below the seat, not shown.
[0012]
FIG. 4 shows the moment when the pilot M jumps out of the airframe while sitting on the seat 1 and releases the parachute in the overhead direction. Just before this, the cover 6 takes an open position as shown in the figure. This is obtained by pulling the drive handle, following a predetermined sequence, and then opening the cover. That is, it is located on both lower sides of both legs of the pilot M. Then, the parachute P is released overhead and opened. At this time, the riser T that suspends the pilot M lifts the pilot M relatively upward due to the resistance caused by the parachute P getting wind. It is done. At this time, the cover 6 is smoothly moved relatively upward without being caught to pull out the pilot M upward, and is separated from the seat 1 as shown in FIG.
[0013]
Further, according to the present embodiment, the cover 6 is separated from the drive shaft 4 and separated from the seat 1. In addition, the horizontal portion of the seat portion 2 is rotated to the left as shown in the drawing, and the survival kit K is housed in a recess formed in the horizontal portion of the seat 1 formed below this. The pilot M is pulled upward by the parachute P while being carried.
[0014]
As described above, the load of the parachute P is only the pilot M and the survival kit K, and the heavy seat 1 and the cover 6 are separated from each other. Since the parachute may be stored in the seat 1, the entire emergency escape device can be further reduced in size.
[0015]
The embodiment of the present invention has been described above. Of course, the present invention is not limited to this, and various modifications can be made based on the technical idea of the present invention.
[0016]
For example, in the above embodiment, the cover 6 is separated from the seat 1 when the pilot M is separated from the open position by the umbrella P, but it may be attached to the seat 1. However, if the cover 6 is separated as in the above embodiment, the pilot M can be easily pulled out by the parachute P.
[0017]
In the above embodiment, when the pilot 6 is covered from the surrounding space by the cover 6, each airbag prevents a part of the body from being damaged when the cover 6 is closed. The present invention is also applicable to the emergency escape device of the above-described disclosed example.
[0018]
In the above embodiment, the open position of the cover 6 is positioned in the vicinity of the leg portion as shown in FIG. 4 when the pilot M escapes with the parachute. Any position may be used as long as the position does not occur. For example, it may be positioned further to the right in FIG.
[0019]
【The invention's effect】
As described above, according to the emergency escape device of the present invention, the load on the parachute can be reduced in the escape device with a cover, and the entire device can be greatly reduced in weight and size.
