Description
本発明は、軟結合構造を介して複数の弾性球状体を結合した衝撃吸収構造体とその製造方法に関するものである。 The present invention relates to an impact absorbing structure in which a plurality of elastic spheres are coupled through a soft coupling structure, and a method for manufacturing the same.
従来、発泡樹脂体からなるベース部材上に、複数の弾力性を有する球体状のセル構造体を並べ、この複数のセル構造体を、ベース部材ごとカバー材により覆うことで形成された衝撃吸収構造体が知られている（例えば、特許文献１参照）。 Conventionally, a shock absorbing structure formed by arranging a plurality of elastic spherical cell structures on a base member made of a foamed resin body and covering the plurality of cell structures with a cover material together with the base member The body is known (see, for example, Patent Document 1).
しかしながら、従来の衝撃吸収構造体にあっては、複数のセル構造体がベース部材上に載置されているのみであるため、カバー材の内側で自由に移動したり回転したりする。そのため、複数のセル構造体が密になった部分では通気性が低下するし、複数のセル構造体の間隔が開きすぎた部分では衝撃吸収性能の低下が懸念される。つまり、セル構造体の状態によって衝撃吸収性能や通気性にむらが生じてしまうという問題があった。 However, in the conventional shock absorbing structure, since the plurality of cell structures are only mounted on the base member, they can freely move or rotate inside the cover material. Therefore, the air permeability is lowered at a portion where the plurality of cell structures are dense, and there is a concern that the shock absorbing performance may be lowered at a portion where the intervals between the plurality of cell structures are too wide. That is, there is a problem that unevenness of shock absorption performance and air permeability occurs depending on the state of the cell structure.
本発明は、上記問題に着目してなされたもので、軟結合構造を介して結合された各弾性球状体の位置や姿勢を安定させ、全面に渡って品質を均一化することができる衝撃吸収構造体とその製造方法を提供することを目的とする。 The present invention has been made by paying attention to the above-mentioned problem, and it is possible to stabilize the position and posture of each elastic spherical body coupled through a soft coupling structure, and to make the quality uniform over the entire surface. An object is to provide a structure and a method for manufacturing the structure.
上記目的を達成するため、本発明は、外形形状が球状であり、外部から加わる外力の大きさと方向に応じて弾性変形する複数の弾性球状体を、互いに乖離する対向球面間に貫通空隙を確保した状態で、前記外力に従って変形可能なように剛性を低く抑えた軟結合構造を介して平面状又は線状に集合させた衝撃吸収構造体において、
前記軟結合構造は、下側布部材と、上側布部材と、を備えている。
前記下側布部材は、前記弾性球状体の下端に、一面に設けた熱溶着層が熱溶着固定される。
前記上側布部材は、前記弾性球状体の上端に、一面に設けた熱溶着層が熱溶着固定される。
To achieve the above object, according to the present invention, a plurality of elastic spherical bodies that have an outer shape of a spherical shape and elastically deform according to the magnitude and direction of external force applied from the outside are secured between opposing spherical surfaces that are separated from each other. In such a state, in the shock absorbing structure assembled in a planar shape or a linear shape through a soft coupling structure with low rigidity so as to be deformable according to the external force,
The soft coupling structure includes a lower cloth member and an upper cloth member.
In the lower cloth member, a heat welding layer provided on one surface is heat-welded and fixed to the lower end of the elastic spherical body.
In the upper cloth member, a heat welding layer provided on one surface is heat-welded and fixed to the upper end of the elastic spherical body.
よって、本発明の衝撃吸収構造体にあっては、弾性球状体の下端が下側布部材の熱溶着層に熱溶着固定されることで、弾性球状体の下側布部材に対する位置や姿勢が固定される。また、弾性球状体の上端が上側布部材の熱溶着層に熱溶着固定されることで、弾性球状体の上側布部材に対する位置や姿勢が固定される。
このため、弾性球状体は、下側布部材と上側布部材の間で位置や姿勢が固定した状態で保持され、形状変化や外力の入力があっても軟結合構造を介して結合した各弾性球状体の位置や姿勢を安定させることができる。これにより、衝撃吸収構造体の全面に渡って品質を均一化することができる。
Therefore, in the shock absorbing structure of the present invention, the lower end of the elastic sphere is thermally welded and fixed to the heat-welded layer of the lower cloth member, so that the position and posture of the elastic sphere with respect to the lower cloth member can be increased. Fixed. Moreover, the position and attitude | position with respect to the upper cloth member of an elastic spherical body are fixed because the upper end of an elastic spherical body is heat-welded and fixed to the heat welding layer of an upper cloth member.
For this reason, the elastic spherical body is held in a state where the position and posture are fixed between the lower cloth member and the upper cloth member, and even if there is a shape change or an external force input, The position and posture of the spherical body can be stabilized. Thereby, quality can be equalized over the entire surface of the shock absorbing structure.

[Method of manufacturing shock absorbing structure]
Next, a method for manufacturing the impact absorbing member 10 of Example 1 will be described.
6A to 6C are diagrams showing a method for manufacturing the shock absorbing structure of Example 1. FIG. 6A shows an elastic spherical body placing process, FIG. 6B shows a lower cloth member covering process, FIG. 6C shows a first pressing process, and FIG. 6B (d) shows a backing sheet peeling process. (E) shows the upper cloth member covering step, (f) in FIG. 6C shows the second pressing step, and (g) shows the cloth member connecting step.
図６Ａ(a)に示す弾性球状体載置工程では、弾性球状体１１の配置パターンＨをあらかじめ記載した台紙Ｄを作業台等の平らな場所に設置し、配置パターンＨに合わせて弾性球状体１１を台紙Ｄ上に載置する。このとき、台紙Ｄに対して各弾性球状体１１の通気孔１３ａ,１３ｂが直交するように向きを合わせて載置する。すなわち、ここでは弾性球状体１１の上側通気孔１３ｂが台紙Ｄに対向する。また、隣接する弾性球状体１１の間は、約１mmあけて配置する。この１mmあけた間隔により貫通空隙Ｋが確保される。 6A (a), a mounting board D in which the arrangement pattern H of the elastic sphere 11 is described in advance is placed on a flat place such as a work table, and the elastic sphere is matched to the arrangement pattern H. 11 is placed on the mount D. At this time, the elastic spherical body 11 is placed with its orientation aligned so that the vent holes 13a, 13b of the elastic spherical body 11 are orthogonal to the mount D. That is, here, the upper vent hole 13b of the elastic spherical body 11 faces the mount D. Moreover, it arrange | positions about 1 mm apart between the adjacent elastic spherical bodies 11. FIG. The through gap K is secured by this 1 mm gap.
図６Ａ(b)に示す下側布材被覆工程では、台紙Ｄ上に載置された弾性球状体１１上に、第１連結シート１４を載置する。このとき、第１連結シート１４の熱溶着層１４ａが弾性球状体１１に接触するように向きを合わせて載置する。すなわちここでは、弾性球状体１１の下側通気孔１３ａが第１連結シート１４の熱溶着層１４ａに対向する。 In the lower cloth material covering step shown in FIG. 6A (b), the first connecting sheet 14 is placed on the elastic spherical body 11 placed on the mount D. At this time, the heat bonding layer 14a of the first connection sheet 14 is placed so as to face the elastic spherical body 11. That is, here, the lower air vent 13 a of the elastic spherical body 11 faces the heat-welded layer 14 a of the first connection sheet 14.
図６Ａ(c)に示す第１プレス工程では、弾性球状体１１上に載置した第１連結シート１４を平型接着プレス機Ｐによって加熱しながら弾性球状体１１に押し付け、熱溶着層１４ａを溶融させて弾性球状体１１に溶着する。
このとき、加熱温度は140℃、加圧時間は４秒にセットする。これにより、熱溶着層１４ａだけでなく、図５に示すように、この熱溶着層１４ａに接触した弾性球状体１１の下側通気孔１３ａの開口縁部が溶融する。このため第１連結シート１４と弾性球状体１１との溶着度合いが向上する。なお、加圧力は、平型接着プレス機Ｐの自重により弾性球状体１１に作用する圧力とする。
In the first pressing step shown in FIG. 6A (c), the first connecting sheet 14 placed on the elastic spherical body 11 is pressed against the elastic spherical body 11 while being heated by the flat adhesive press machine P, and the thermal welding layer 14a is applied. It is melted and welded to the elastic spherical body 11.
At this time, the heating temperature is set to 140 ° C. and the pressurization time is set to 4 seconds. As a result, not only the heat-welded layer 14a but also the opening edge of the lower vent hole 13a of the elastic spherical body 11 in contact with the heat-welded layer 14a is melted as shown in FIG. For this reason, the welding degree of the 1st connection sheet | seat 14 and the elastic spherical body 11 improves. The applied pressure is a pressure that acts on the elastic spherical body 11 by its own weight of the flat type adhesive press machine P.
図６Ｂ(d)に示す台紙剥離工程では、第１連結シート１４が溶着した弾性球状体１１を引っくり返し、第１連結シート１４を下側にしてから、弾性球状体１１から台紙Ｄを剥がす。 In the mount peeling process shown in FIG. 6B (d), the elastic spherical body 11 to which the first connecting sheet 14 is welded is turned over, the first connecting sheet 14 is turned down, and then the mount D is peeled from the elastic spherical body 11.
図６Ｂ(e)に示す上側布部材被覆工程では、第１連結シート１４に固定された弾性球状体１１上に、第２連結シート１５を載置する。このとき、第２連結シート１５の熱溶着層１５ａが弾性球状体１１に接触するように向きを合わせて載置する。すなわちここでは、弾性球状体１１の上側通気孔１３ｂが第２連結シート１５の熱溶着層１５ａに対向する。 In the upper cloth member covering step shown in FIG. 6B (e), the second connecting sheet 15 is placed on the elastic spherical body 11 fixed to the first connecting sheet 14. At this time, the heat bonding layer 15 a of the second connection sheet 15 is placed so as to be oriented so as to contact the elastic spherical body 11. That is, here, the upper air vent 13 b of the elastic spherical body 11 faces the heat-welded layer 15 a of the second connection sheet 15.
図６Ｃ(f)に示す第２プレス工程では、弾性球状体１１上に載置した第２連結シート１５を平型接着プレス機Ｐによって加熱しながら弾性球状体１１に押し付け、熱溶着層１５ａを溶融させて弾性球状体１１に溶着する。
このとき、加熱温度は140℃、加圧時間は４秒にセットする。これにより、熱溶着層１５ａだけでなく、図５に示すように、この熱溶着層１５ａに接触した弾性球状体１１の上側通気孔１３ｂの開口縁部が溶融する。このため第２連結シート１５と弾性球状体１１との溶着度合いが向上する。なお、加圧力は、平型接着プレス機Ｐの自重により弾性球状体１１に作用する圧力とする。
In the second pressing step shown in FIG. 6C (f), the second connecting sheet 15 placed on the elastic spherical body 11 is pressed against the elastic spherical body 11 while being heated by the flat adhesive press machine P, and the thermal welding layer 15a is applied. It is melted and welded to the elastic spherical body 11.
At this time, the heating temperature is set to 140 ° C. and the pressurization time is set to 4 seconds. Thereby, not only the heat welding layer 15a but also the opening edge portion of the upper vent hole 13b of the elastic spherical body 11 in contact with the heat welding layer 15a is melted as shown in FIG. For this reason, the welding degree of the 2nd connection sheet 15 and the elastic spherical body 11 improves. The applied pressure is a pressure that acts on the elastic spherical body 11 by its own weight of the flat type adhesive press machine P.
図６Ｃ(g)に示す布部材連結工程では、第１連結シート１４と第２連結シート１５のそれぞれに対して溶着固定された弾性球状体１１の周囲位置を、図示しないアイロンにより加熱しながら加圧し、第１連結シート１４の熱溶着層１４ａと第２連結シート１５の熱溶着層１５ａを接着する。その後、接着した弾性球状体１１の周りの第１連結シート１４と第２連結シート１５をミシンで縫い合わせ、その縫い目の周りの余分な第１,第２シート１４,１５を切り落とす。これにより、衝撃吸収部材１０を製造する。 In the cloth member connecting step shown in FIG. 6C (g), the peripheral position of the elastic spherical body 11 welded and fixed to each of the first connecting sheet 14 and the second connecting sheet 15 is heated while being heated by an iron (not shown). The heat-welding layer 14a of the first connecting sheet 14 and the heat-welding layer 15a of the second connecting sheet 15 are bonded together. Thereafter, the first connecting sheet 14 and the second connecting sheet 15 around the bonded elastic spherical body 11 are sewn together with a sewing machine, and excess first and second sheets 14 and 15 around the seam are cut off. Thereby, the shock absorbing member 10 is manufactured.
次に、実施例１の衝撃吸収構造体における作用を、「弾性球状体の姿勢安定化作用」、「衝撃吸収性能確保作用」、「通気性能確保作用」、「形状自由度向上作用」、「製造方法における特徴的作用」に分けて説明する。 Next, the effects of the shock absorbing structure of Example 1 are as follows: “Attitude stabilizing action of elastic spherical body”, “Shock absorbing performance securing action”, “Breathing performance securing action”, “Shape freedom improving action”, “ The description will be divided into “characteristic actions in the manufacturing method”.
[弾性球状体の姿勢安定化作用]
実施例１の衝撃吸収部材１０の軟結合構造１２は、弾性球状体１１の下端１１ａに、一面に設けた熱溶着層１４ａが熱溶着固定される第１連結シート１４と、弾性球状体１１の上端１１ｂに、一面に設けた熱溶着層１５ａが熱溶着固定される第２連結シート１５と、を備えている。
[Attitude stabilization of elastic sphere]
The soft coupling structure 12 of the impact absorbing member 10 of Example 1 includes a first connection sheet 14 in which a heat-welded layer 14 a provided on one surface is thermally welded and fixed to the lower end 11 a of the elastic sphere 11, and the elastic sphere 11. The upper end 11b is provided with a second connection sheet 15 to which a heat welding layer 15a provided on one surface is fixed by heat welding.
このため、弾性球状体１１の下端１１ａが第１連結シート１４の熱溶着層１４ａに熱溶着固定されることで、第１連結シート１４に対する弾性球状体１１の位置や姿勢が固定される。また、弾性球状体１１の上端１１ｂが第２連結シート１５の熱溶着層１５ａに熱溶着固定されることで、第２連結シート１５に対する弾性球状体１１の位置や姿勢が固定される。これにより、第１,第２連結シート１４,１５が変形しても、弾性球状体１１は第１,第２連結シート１４,１５に対して移動したり、回転することはない。 For this reason, the position and posture of the elastic spherical body 11 with respect to the first connection sheet 14 are fixed by the lower end 11a of the elastic spherical body 11 being thermally welded and fixed to the heat welding layer 14a of the first connection sheet 14. Further, the upper end 11 b of the elastic spherical body 11 is thermally welded and fixed to the heat welding layer 15 a of the second connection sheet 15, so that the position and posture of the elastic spherical body 11 with respect to the second connection sheet 15 are fixed. Thereby, even if the 1st, 2nd connection sheets 14 and 15 deform | transform, the elastic spherical body 11 does not move with respect to the 1st, 2nd connection sheets 14 and 15, or rotates.
この結果、弾性球状体１１は、第１連結シート１４と第２連結シート１５の間で位置や姿勢が固定した状態で保持され、弾性球状体１１の姿勢の安定化を図ることができる。 As a result, the elastic spherical body 11 is held in a state where the position and posture are fixed between the first connecting sheet 14 and the second connecting sheet 15, and the posture of the elastic spherical body 11 can be stabilized.
特に、実施例１の衝撃吸収部材１０では、弾性球状体１１の下側通気孔１３ａが第１連結シート１４に対向し、上側通気孔１３ｂが第２連結シート１５に対向している。そのため、下側通気孔１３ａの開口周縁や上側通気孔１３ｂの開口周縁が各連結シート１４,１５にそれぞれ溶着する。これにより、対向球面１１ｃに各連結シート１４,１５を溶着する場合よりも溶着面積を小さくすることができ、第１,第２連結シート１４,１５の溶着によるひずみを小さく抑えることができる。そして、第１,第２連結シート１４,１５のひずみを抑えることで、第１,第２連結シート１４,１５間に保持された複数の弾性球状体１１をより整然と揃えることができて、姿勢の安定化をさらに図ることができる。 In particular, in the impact absorbing member 10 of Example 1, the lower air vent 13 a of the elastic spherical body 11 faces the first connecting sheet 14, and the upper air vent 13 b faces the second connecting sheet 15. Therefore, the opening periphery of the lower vent 13a and the opening periphery of the upper vent 13b are welded to the connection sheets 14 and 15, respectively. Thereby, a welding area can be made smaller than the case where each connection sheet | seat 14 and 15 is welded to the opposing spherical surface 11c, and the distortion by welding of the 1st, 2nd connection sheet | seat 14 and 15 can be restrained small. And by suppressing the distortion of the first and second connecting sheets 14 and 15, the plurality of elastic spherical bodies 11 held between the first and second connecting sheets 14 and 15 can be more orderly aligned, and the posture Can be further stabilized.
また、実施例１の衝撃吸収部材１０では、第１,第２連通シート１４,１５のそれぞれに固定された状態で集合した複数の弾性球状体１１の周囲位置において、連結手段１６を介してこの第１,第２連結シート１４,１５を連結している。 Further, in the impact absorbing member 10 of the first embodiment, this is connected via the connecting means 16 at the peripheral positions of the plurality of elastic spherical bodies 11 assembled in a state of being fixed to the first and second communication sheets 14 and 15. The first and second connecting sheets 14 and 15 are connected.
そのため、第１,第２連結シート１４,１５同士が連結することで、この第１,第２連結シート１４,１５の相対的な位置がずれにくくなり、その間に保持された弾性球状体１１の姿勢の安定化をさらに図ることができる。 Therefore, when the first and second connection sheets 14 and 15 are connected to each other, the relative positions of the first and second connection sheets 14 and 15 are less likely to be shifted, and the elastic spherical body 11 held therebetween is The posture can be further stabilized.
特に、ここでは、連結手段１６が溶着部１６ａと縫合部１６ｂを有しているため、溶着部１６ａのみの場合や、縫合部１６ｂのみの場合よりも連結強度を高めることができ、第１,第２連結シート１４,１５の相対的な位置ずれをより効果的に防止することができる。 In particular, here, since the connecting means 16 has the welded portion 16a and the stitched portion 16b, the coupling strength can be increased compared to the case of only the welded portion 16a or the stitched portion 16b. The relative displacement of the second connecting sheets 14 and 15 can be more effectively prevented.
[衝撃吸収性能確保作用]
実施例１の衝撃吸収部材１０に外部から外力が入力すると、この外力の大きさと方向に応じて弾性球状体１１が弾性変形し、外力による衝撃を吸収する。このとき、弾性球状体１１は、外径形状がほぼ球状であるため、全方位からの衝撃吸収性能を発揮する。
[Shock absorption performance securing action]
When an external force is input to the impact absorbing member 10 of the first embodiment from the outside, the elastic spherical body 11 is elastically deformed according to the magnitude and direction of the external force and absorbs the impact due to the external force. At this time, since the outer spherical shape of the elastic spherical body 11 is substantially spherical, it exhibits impact absorbing performance from all directions.
さらに、この弾性球状体１１が第１,第２連結シート１４,１５に溶着され、移動したり、回転することはないため、入力した外力を受け止めて確実に変形することができ、衝撃吸収性能を確保することができる。すなわち、入力した外力によって弾性球状体１１が第１,第２連結シート１４,１５に対して移動したり、回転したりすると、弾性球状体１１が部分的に弾性変形しない場合があり、十分に衝撃を吸収することができない。 Further, since the elastic spherical body 11 is welded to the first and second connecting sheets 14 and 15 and does not move or rotate, the elastic spherical body 11 can be reliably deformed by receiving the input external force, and has an impact absorbing performance. Can be secured. That is, if the elastic spherical body 11 is moved or rotated with respect to the first and second connecting sheets 14 and 15 by the input external force, the elastic spherical body 11 may not be partially elastically deformed. The shock cannot be absorbed.
これに対し、実施例１の衝撃吸収部材１０では、外力の大きさと方向に応じて弾性球状体１１が移動することなく確実に弾性変形して衝撃を吸収することができるため、衝撃吸収部材１０の全面に渡って衝撃吸収性能を均一化することができる。 In contrast, in the impact absorbing member 10 of the first embodiment, the elastic spherical body 11 can be reliably elastically deformed and absorb the impact without moving according to the magnitude and direction of the external force. The shock absorbing performance can be made uniform over the entire surface.
さらに、軟結合構造１２である第１連結シート１４及び第２連結シート１５は、弾性球状体１１の弾性変形に追従して変形するため、弾性球状体１１の弾性変形を阻害することはなく、衝撃吸収性能は確保される。 Furthermore, since the first connection sheet 14 and the second connection sheet 15 that are the soft coupling structure 12 are deformed following the elastic deformation of the elastic spherical body 11, the elastic deformation of the elastic spherical body 11 is not hindered. Shock absorbing performance is ensured.
[通気性能確保作用]
実施例１の衝撃吸収部材１０では、弾性球状体１１が下端１１ａと上端１１ｂとの間を貫通し、貫通空隙Ｋを介して第１連結シート１４から第２連結シート１５へ通過する空気の流線と平行な通気流線を加える下側通気孔１３ａ及び上側通気孔１３ｂを有している。そして、下側通気孔１３ａの開口周縁を第１連結シート１４に溶着し、上側通気孔１３ｂを第２連結シート１５に溶着している。つまり、弾性球状体１１の下側通気孔１３ａが第１連結シート１４に対向し、上側通気孔１３ｂが第２連結シート１５に対向した状態で、第１,第２連結シート１４,１５間に保持されている。
[Ensuring airflow performance]
In the impact absorbing member 10 of the first embodiment, the elastic spherical body 11 passes between the lower end 11a and the upper end 11b, and the air flow passes from the first connecting sheet 14 to the second connecting sheet 15 through the through gap K. It has a lower air hole 13a and an upper air hole 13b for adding an air flow line parallel to the line. Then, the opening periphery of the lower vent 13 a is welded to the first connecting sheet 14, and the upper vent 13 b is welded to the second connecting sheet 15. That is, with the lower air hole 13a of the elastic spherical body 11 facing the first connecting sheet 14 and the upper air hole 13b facing the second connecting sheet 15, the first and second connecting sheets 14 and 15 are interposed. Is retained.
そのため、第１連結シート１４側から流れる空気は、第１連結シート１４を通過した後、隣接する弾性球状体１１の互いに乖離する対向球面１１ｃ間の貫通空隙Ｋを通過するか、あるいは、下側通気孔１３ａから弾性球状体１１の内部に入り込んで上側通気孔１３ｂから排出される。そして、第２連通シート１５を通過して流れる。 Therefore, the air flowing from the first connecting sheet 14 side passes through the first connecting sheet 14 and then passes through the through gap K between the opposing spherical surfaces 11 c of the adjacent elastic spherical bodies 11 or the lower side. It enters the inside of the elastic spherical body 11 from the vent hole 13a and is discharged from the upper vent hole 13b. Then, it flows through the second communication sheet 15.
このとき、弾性球状体１１が第１,第２連結シート１４,１５に溶着され、移動したり、回転することはないため、貫通空隙Ｋが確実に確保されると共に、下側通気孔１３ａ及び上側通気孔１３ｂの方向は規定される。そのため、弾性球状体１１が第１連結シート１４から第２連結シート１５へと流れる空気の流れを阻害することはなく、衝撃吸収部材１０の全面に渡って一定の通気性能を確保することができる。 At this time, since the elastic spherical body 11 is welded to the first and second connecting sheets 14 and 15 and does not move or rotate, the through-hole K is reliably secured, and the lower air vent 13a and The direction of the upper vent 13b is defined. Therefore, the elastic spherical body 11 does not hinder the flow of air flowing from the first connection sheet 14 to the second connection sheet 15, and a certain ventilation performance can be ensured over the entire surface of the shock absorbing member 10. .
[形状自由度向上作用]
実施例１の衝撃吸収部材１０では、複数の弾性球状体１１を平面状に配置し、第１連結シート１４と第２連結シート１５によって挟んでいる。そのため、この弾性球状体１１の配置パターンを任意の形状にすることで、衝撃吸収部材１０の形状を自由に設定することができる。これにより、衝撃吸収部材１０を四角型や丸型等形状自由度を向上することができる。
[Shape flexibility improvement]
In the impact absorbing member 10 of Example 1, a plurality of elastic spherical bodies 11 are arranged in a planar shape and are sandwiched between a first connecting sheet 14 and a second connecting sheet 15. Therefore, the shape of the shock absorbing member 10 can be freely set by making the arrangement pattern of the elastic spherical bodies 11 an arbitrary shape. Thereby, it is possible to improve the degree of freedom of shape of the shock absorbing member 10 such as a square shape or a round shape.
特に、この実施例１の衝撃吸収部材１０では、頂天部３に設けられた第１シートポケット６と、側面部４に設けられた第２シートポケット７との形状が異なっている。しかし、それぞれ形状に合わせて衝撃吸収部材１０を形成することができ、頂天部３や側面部４の全面を衝撃吸収部材１０でカバーすることができる。 In particular, in the impact absorbing member 10 of the first embodiment, the shape of the first seat pocket 6 provided in the top portion 3 and the second seat pocket 7 provided in the side surface portion 4 are different. However, the impact absorbing member 10 can be formed in accordance with each shape, and the entire top portion 3 and side surface portion 4 can be covered with the impact absorbing member 10.
[製造方法における特徴的作用]
実施例１の衝撃吸収部材１０を製造するには、第１プレス工程（図６Ａ(c)）において、台紙Ｄ上に載置された複数の弾性球状体１１に第１連結シート１４を加温しながら押圧して溶着し、その後、第２プレス工程（図６Ｃ(f)）において、第１連結シート１４上に固定された複数の弾性球状体１１に第２連結シート１５を加温しながら押圧して溶着する。
[Characteristic effects in manufacturing methods]
In order to manufacture the impact absorbing member 10 of Example 1, the first connecting sheet 14 is heated to the plurality of elastic spherical bodies 11 placed on the mount D in the first pressing step (FIG. 6A (c)). The second connecting sheet 15 is then heated to the plurality of elastic spherical bodies 11 fixed on the first connecting sheet 14 in the second pressing step (FIG. 6C (f)). Press to weld.
このため、複数の弾性球状体１１を第１連結シート１４や第２連結シート１５に一斉に溶着することができ、各弾性球状体１１の姿勢や間隔がずれることなく、短時間で衝撃吸収部材１０を製造することができる。 For this reason, a plurality of elastic spherical bodies 11 can be welded to the first connecting sheet 14 and the second connecting sheet 15 all at once, and the impact absorbing member can be quickly assembled without any deviation in the posture or interval of the elastic spherical bodies 11. 10 can be manufactured.
さらに、実施例１では、第１,第２連結シート１４,１５に対して溶着固定されて集合した複数の弾性球状体１１の周囲位置において、第１,第２連結シート１４,１５を連結する布部材連結工程(図６Ｃ(g))を備えている。 Furthermore, in Example 1, the 1st, 2nd connection sheet | seats 14 and 15 are connected in the peripheral position of the some elastic spherical body 11 which was welded and fixed with respect to the 1st and 2nd connection sheet | seats 14 and 15. A cloth member connecting step (FIG. 6C (g)) is provided.
そのため、第１,第２連結シート１４,１５同士が連結することで、この第１,第２連結シート１４,１５の相対的な位置がずれにくくなり、その間に保持された弾性球状体１１の姿勢安定化をさらに図ることができる。 Therefore, when the first and second connection sheets 14 and 15 are connected to each other, the relative positions of the first and second connection sheets 14 and 15 are less likely to be shifted, and the elastic spherical body 11 held therebetween is The posture can be further stabilized.
特に、ここでは、布部材連結工程（図６Ｃ(g)）が、第１連結シート１４の熱溶着層１４ａと第２連結シート１５の熱溶着層１５ａとを圧着すると共に、圧着箇所を縫い合わせている。そのため、第１,第２連結シート１４,１５同士の連結強度を高めると共に、連結しやすくなる。 In particular, here, the cloth member connecting step (FIG. 6C (g)) presses the heat-welding layer 14a of the first connecting sheet 14 and the heat-welding layer 15a of the second connecting sheet 15 together, and stitches the pressure-bonding portions. Yes. Therefore, the connection strength between the first and second connection sheets 14 and 15 is increased and the connection is facilitated.
