There is no hindrance to dynamic sliding.
上記のように、外側部材は、剪断部材の固定作用と、
被剪断部材の摺動ガイド作用と、肉部破片の外部への飛
散防止作用とを兼ねている。As described above, the outer member has a securing action of the shearing member,
It has both a sliding guide function of the sheared member and a function of preventing the flesh fragments from scattering to the outside.

At the front end of the sheared member 13, a mounting hole 19 for bolting to the front mounting plate 9 is provided. Further, a metal reinforcing plate 20 is superposed on the upper surface, the front end surface, and the lower surface of the front end portion, and reinforces the front end portion so that the front end portion is not broken when impact energy described below is applied. A plurality (10 in the figure) of through-holes 21 are formed on both side walls of the sheared member 13 in the axial direction.
Are arranged side by side with a meat portion 22 therebetween, and the through holes 21 on both side walls face each other in a direction perpendicular to the axis. here,
The foremost through hole 21a is formed with a minimum hole diameter through which the shearing member 14 can be inserted, and the other through holes 21 are formed with a larger hole diameter. The length, width, and thickness of each of the meat portions 22 are constant in the present embodiment, but, for example, the length of the meat portion 22 is gradually increased, shortened, or randomized toward the rear side. Or may be unequal.

る。The shearing member 14, as shown in FIGS. 2 and 4,
In this embodiment, a bolt is inserted into the through-hole 18 and the through-hole 21a in a state where the through-hole 18 of the outer member and the through-hole 21a at the foremost end of the sheared member 13 are aligned with each other. The nut 23 is fixed to both side walls of the outer member 12 by the combined nut 23.

る。When an impact force is applied to the shearing member 14 and the sheared member 13, the impact energy absorbing device 11 causes the shearing member 14 to reduce the flesh 22 between the through holes 21 of the sheared member 13 due to the axial component. The members are sheared in order, but the size, thickness, strength and the like of each member are set so as not to break the other parts.
以上のように構成され、航空機用座席１に取り付けら
れた衝撃エネルギ吸収装置11について、次にその作用及
び効果を説明する。Next, the operation and effect of the impact energy absorbing device 11 configured as described above and attached to the aircraft seat 1 will be described.
まず、この衝撃エネルギ吸収装置11は上記の通り構造
が簡単で、従来からある航空機用座席１の脚部に対して
その脚部品の構造変更を強いることなく容易に取り付け

通している挿通孔18及び最前端の貫通孔21aは前記の通

両孔18,21aとの間にがたが生ずることはない。First, the impact energy absorbing device 11 has a simple structure as described above, and can be easily attached to the leg of the conventional aircraft seat 1 without forcing a structural change of the leg component. In the normal state shown in FIG. 1 (solid line) and FIG. 2, the impact energy absorbing device 11
And the center part of the rear leg 3 is connected to provide an effect of reinforcing the aircraft seat 1. At this time, since the insertion hole 18 through which the shearing member 14 is inserted and the foremost through hole 21a are formed with the minimum hole diameter as described above, between the shearing member 14 and the two holes 18, 21a. There will be no rattling.
次に、例えば航空機の離着陸時に事故が起こり、その

座席１に生ずる慣性力により前後の基体6,7はスプレダ
ー８を介して同時に前方へ押圧されるため、前脚２は前
方へ傾斜し、後脚３は前方へ傾斜するとともに湾曲が戻
るように変形する。Next, for example, when an accident occurs at the time of takeoff and landing of an aircraft, and the impact energy at that time cannot be completely absorbed only by deformation of the fuselage, excess impact energy is added to the passenger and the seat 1. At this time, as shown by a chain line in FIG.
The front and rear substrates 6, 7 are simultaneously pressed forward by the inertia force generated in the seat 1 via the spreader 8, so that the front leg 2 is inclined forward, and the rear leg 3 is inclined forward and deformed so that the curve returns. I do.

部22を次々と剪断して３番目以降の貫通孔21に進入し、
衝撃エネルギが十分に吸収された時点で剪断は停止す
る。Then, the distance between the upper end of the front leg 2 and the center of the rear leg 3 becomes longer than usual, so that the sheared member 13 attached to the front attachment plate 9 and the outer member attached to the rear attachment plate 10 12 is subjected to an impact tensile force in the axial direction, and the sheared member 13 moves forward and tries to escape from the outer member 12. As the sheared member 13 advances, the shearing member 14 first shears the meat portion 22 from the foremost through hole 21a and enters the second through hole 21, so that the surplus impact energy is applied to the meat portion 22. It will be consumed as shear energy. If the impact energy is not consumed only by the shearing of the meat portion 22, the sheared member 13 continues to advance further, and the shearing member 14 shears the meat portion 22 one after another to the third and subsequent through holes 21. Enter,
The shearing stops when the impact energy has been sufficiently absorbed.
前述の通り各々の肉部22の長さ、幅及び厚さは一定な
ので、いずれの肉部22を剪断するときの衝撃荷重も略均
一となり、変位の増加に伴う衝撃荷重の変化が少ない安
定した結果が得られる。なお、剪断された肉部22の破片
は四角筒状の被剪断部材13の内部に飛び散るため、該破
片が被剪断部材13の前進を妨げるようなことはない。As described above, since the length, width, and thickness of each meat portion 22 are constant, the impact load when shearing any meat portion 22 becomes substantially uniform, and the change in the impact load with an increase in displacement is small and stable. The result is obtained. Since the sheared pieces of the meat portion 22 are scattered inside the sheared member 13 having a rectangular tube shape, the pieces do not hinder the forward movement of the sheared member 13.
本実施例の航空機用座席１について16G衝撃試験を行
ったところ、剪断部材14は５箇所の肉部22を次々と剪断
し、前から６番目の貫通孔21に進入して剪断を停止し
た。第１図の鎖線及び第３図はこのときの状態を示して
いる。When a 16G impact test was performed on the aircraft seat 1 of this embodiment, the shearing member 14 sheared the five meat portions 22 one after another, and entered the sixth through hole 21 from the front to stop the shearing. The chain line in FIG. 1 and FIG. 3 show the state at this time.
また、上記衝撃荷重及び衝撃エネルギの吸収量の変更
は、肉部22の長さ、幅、厚さ、数量、材料等を変更した
り、剪断部材14の直径を変更したりすることにより容易
に行うことができる。In addition, the absorption amount of the impact load and the impact energy can be easily changed by changing the length, width, thickness, quantity, material, and the like of the meat portion 22, or by changing the diameter of the shearing member 14. It can be carried out.
（第二実施例） 第５図に示す第二実施例は、衝撃エネルギ吸収装置11

例と相違している。(Second Embodiment) A second embodiment shown in FIG.
The outer member 12 is bolted to the lower end of the front leg 2 and the sheared member 13 is also bolted to the rear mounting plate 10 of the rear leg 3 to use the impact energy absorbing device 11 as a compression energy absorbing type. The first embodiment differs from the first embodiment only in that the number of through holes 21 of the sheared member 13 is six.
本実施例の航空機用座席１に衝撃エネルギが加わった

て、本実施例も第一実施例と同様の効果を奏する。When impact energy is applied to the aircraft seat 1 of the present embodiment, as shown by a chain line in FIG. 5, an impact compression force is applied to the sheared member 13 and the outer member 12 in the axial direction. 13 tries to get inside the outer member 12. At this time, since the shearing member 14 shears the meat portion 22 from the foremost through hole 21a and enters the second and subsequent through holes 21, the impact energy is consumed as the shear energy of the meat portion 22. Therefore, the present embodiment also has the same effect as the first embodiment.
なお、本考案は前記実施例の構成に限定されるもので
