Description

【図面の簡単な説明】[Brief explanation of the drawing]

第１図は中間部材、ステーの他端部を包み込ん
だカバー部材の断面図（第３図の―線断面図
）であり、第２図は傾動式ヘツドレストの断面図
であり、第３図は中間部材、ステーの他端部を包
み込んだカバー部材の概略斜視図、第４図は中間
部材、ステーの他端部を包み込んだカバー部材の
半分を示す正面図である。図中、１はステー、１ａは一端部、１ｂは他端
部、２は中間部材、３はカバー部材、４は緩衝体
、５は摩擦摺動部（回動部）、６はボルト（固定
具）、７はナツト（固定具）をそれぞれ示す。 Figure 1 is a cross-sectional view of the cover member that wraps around the intermediate member and the other end of the stay (cross-sectional view taken along the - line in Figure 3), Figure 2 is a cross-sectional view of the tilting headrest, and Figure 3 is a cross-sectional view of the tilting headrest. FIG. 4 is a schematic perspective view of a cover member that wraps around the intermediate member and the other end of the stay. FIG. 4 is a front view showing half of the cover member that wraps around the intermediate member and the other end of the stay. In the figure, 1 is a stay, 1a is one end, 1b is the other end, 2 is an intermediate member, 3 is a cover member, 4 is a buffer, 5 is a friction sliding part (rotating part), 6 is a bolt (fixed) (fixing tool) and 7 indicate nuts (fixing tools), respectively.
