To provide a mat installation structure in which the linear part of a guide wire moves smoothly vertically in the insertion hole of a seat back frame in the usual longitudinal movement of a mat, and dropping out of the linear part from the insertion hole is prevented when the linear part moves significantly backward the mat.SOLUTION: A mat installation structure comprises a guide wire installed to a mat and having at a top, a linear part 6d3 extending in a longitudinal direction in the top side of a seat back frame, and a through-hole 4a which is formed to the seat back frame and in which the linear part 6d3 is insertable. In a first movement of the mat accompanying occupant seating, the linear part 6d3 moves in a dropping-out direction while contacting a high protrusion part 4b1, and a contacting position moves toward a low protrusion part 4b2 as the movement amount of the mat becomes large compared to that of the first movement.SELECTED DRAWING: Figure 5

    【課題】マットの通常の前後移動ではガイドワイヤの直状部がシートバックフレームの挿通孔内を滑らかに上下動しマットの後方への移動量が大きい場合には直状部の挿通孔からの抜けを防止できるマット取付構造を提供する。【解決手段】マットに取り付けられシートバックフレームの先端側においてその長手方向に延びる直状部6d3を先端に有したガイドワイヤとシートバックフレームに形成され直状部6d3が挿通可能な貫通孔4aとを備える。乗員着座に伴うマットの第1移動では、直状部6d3が高突出部4b1に接触しながら抜き方向に移動し、マットの移動量が第1移動の移動量から大きくなる程、接触位置が低突出部4b2に向け移動する。【選択図】図5
