Claims

[Claims for Utility Model Registration] 1. In an automobile seat consisting of a seat back and a seat bottom, the seat back is supported by a seat back frame and the seat back frame, and changes the curve of the seat surface in the front-rear direction of the seat. The seat curve converting means includes a plurality of horizontal rods arranged in the width direction of the seat and supported so as to be movable in the longitudinal direction of the seat, and a plurality of horizontal rods that are movable in the vertical direction of the seat. 1. An automobile seat comprising: an operating plate that operates the horizontal rod in the longitudinal direction by being moved; and a drive means that moves the operating plate. 2. The automobile seat according to claim 1, wherein the plurality of horizontal rods are connected to each other by a band-shaped elastic plate, and the elastic plate is arranged on the seat surface side of the horizontal rod. 3. The operating plate is provided with a plurality of guide passages, and the guide passages are arranged in the vertical direction so that when the operating plate moves in the vertical direction of the seat, the horizontal rod is operated in the longitudinal direction of the seat. 3. The automobile seat according to claim 1 or 2, wherein the seat is arranged diagonally. 4. The driving means according to any one of claims 1 to 3, characterized in that the driving means is composed of a rotary motor and a driving force converting means that converts the rotational force of the rotary motor into a vertical force that operates the actuating plate. The automobile seat described in any of the above.
