To provide a vibration absorbing device of a seat which can absorb and mitigate impact and vibration in a horizontal direction with a simple structure.SOLUTION: When vibration in a horizontal direction is applied from the above of a vehicle body, a mounting stand 3 moves to the rear part together with the vehicle body, and accordingly a support shaft 7 moves to the rear part together. Due to movement of the support shaft 7 to the rear part, a link piece 12 rotates in a clockwise direction with the support shaft 7 as a supporting point, and an outer frame 6 also similar rotates in a clockwise direction while deforming each rubber 10 so as to crush the rubbers. At this time, a connection pin 13A rotates a link piece 14A with the connection pin 18A as the supporting point in a counterclockwise direction while moving to the inside of a long hole 17A, and rotates a link piece 14B in a clockwise direction with a connection point 18A as the supporting point. Because of this, rollers 20A1, 20A2, 20B1 and 20B2 arranged on association shafts 19A and 19B rotate while being guided by each of the guide members 4, the mounting stand 3 moves to the rear part, but fitting bodies 15A and 15B and a seat 2 do not move from their positions.SELECTED DRAWING: Figure 4
【課題】簡単な構造で水平方向の衝撃や振動を吸収緩和できる座席シートの振動吸収装置を提供すること。【解決手段】車体の前方から水平方向の振動等が加わると、取付台3も車体と共に後方へ移動するため支軸7は一緒に後方へ移動する。この支軸7の後方への移動に伴い、リンク片12が支軸7を支点として時計方向に回動して外枠6も各ゴム10を押しつぶすように変形させつつ同じく時計方向に回動する。このとき、連結ピン13Aが長孔17A内を移動しながらリンク片14Aを連結ピン18Aを支点として反時計方向に回動させると共にリンク片14Bを連結ピン18Bを支点として時計方向に回動させる。このため、連動軸19A、19Bに配設されたローラー20A1、20A2、20B1、20B2が各ガイド部材4に案内されながら回動し、取付台3は後方へ移動することになるが、取付体15A、15B及び座席シート2はそのままの位置から移動はしない。【選択図】図4
