PROBLEM TO BE SOLVED: To solve such the problem that a seat back adjusting device of a vehicle seat for holding a seating posture of a seated person when traveling a sharp curve cannot be provided inside the conventional seat back without changing the configuration of the seat back.SOLUTION: Left and right side arms 40 (40 L, 40R) whose lower ends are connected to connection shafts 50 (50 L, 50R) and which can be tilted in a longitudinal direction with the connection shafts as a center are provided in lower parts of side frames of a seat back. Raised amounts (tilt angles) of the left and right side arms 40 in a forward direction are determined respectively based on data of a vehicle and data of a seated person. Fist and second drive means 52 L, 52R are driven according to the raised amounts. The left and right connection shafts are independently turned by the drive of the drive means and the left and right side arms 40 are tilted in the forward direction. The side arms push out seat pads of seat back side parts (raised parts), and the raised parts sandwich the seated person to prevent the seated person from falling.SELECTED DRAWING: Figure 2
【課題】急カーブの走行時において着座者の着座姿勢を保持する車両用シートのシートバック調整装置を、従来のシートバックの構成を変更せずにその内部に設けることはできない。【解決手段】シートバックのサイドフレームの下部に、その下端が連結軸50(50L、50R)により連結され、連結軸を中心に前後方向に傾動可能な左右のサイドアーム40(40L、40R)が設けられている。車両のデータ、着座者のデータにより左右のサイドアーム40の前方向への隆起量(傾動角度)がそれぞれ判断され、隆起量に応じて第1、第2の駆動手段52L、52Rが駆動される。駆動手段の駆動により左右の連結軸がそれぞれ独立に回動され、左右のサイドアーム40が前方向へ傾動される。サイドアームは、その前方向のシートバック側部(隆起部)のシートパッドを押し出し、隆起部が着座者を挟んで着座者の倒れを防止する。【選択図】図2
