The invention provides a seat driving device capable of improving the retaining property of a side support of a seat to a user. A seat drive device (40) is provided with: a base (100) fixed to a seat (10); a paddle (200) that is rotatably supported by the base (100) and that displaces the side support (22) toward the seating area of the user by rotating in the deployment direction (R1); and an air bag (300) which is disposed between the base (100) and the paddle (200) and which rotates the paddle (200) in the deployment direction (R1) by the expansion of the air supply. The paddle (200) has a pressing part (240) that presses the side support (22) from the inside, and an arm (220) that is rotatably supported by the base (100) and extends toward the pressing part (240). The arm (220) is bent in a storage direction (R2) which is a direction opposite to the unfolding direction (R1).
本发明提供一种能够提高座椅的侧支撑件对使用者的保持性的座椅驱动装置。座椅驱动装置(40)具备:固定于座椅(10)的基座(100);能够旋转地支承于基座(100),通过向展开方向(R1)旋转使侧支撑件(22)朝向使用者的落座区域位移的桨(200);以及配置于基座(100)与桨(200)之间,通过伴随着供气的膨胀使桨(200)向展开方向(R1)旋转的空气袋(300)。桨(200)具有从内侧按压侧支撑件(22)的按压部(240)和能够旋转地支承于基座(100)且朝向按压部(240)延伸的臂(220)。臂(220)朝向作为展开方向(R1)的反方向的收纳方向(R2)弯曲。
