The invention discloses a synchronous overturning and extending mechanism for an automobile seat leg support, which comprises a base and a rotating base body rotatably mounted on the base, a driving cross rod and an extending plate are slidably mounted on the rotating base body, a guide block is slidably matched with the end part of the driving cross rod, and the extending plate is slidably matched with the end part of the driving cross rod. The sliding direction of the guide block relative to the driving transverse rod is perpendicular to the sliding direction of the driving transverse rod relative to the rotating base body in the space, one side of the guide block is rotationally connected to the base, the rotating center of the guide block is eccentrically arranged relative to the rotating center of the rotating base body, and the rotating base body rotates. And the driving cross rod can be driven to slide on the rotating base body through the guide block. The device has the beneficial effects that through the eccentrically-arranged guide block, when the rotating base body rotates, the guide block can bear eccentric force, the eccentric force can force the driving cross rod to slide on the rotating base body, and therefore synchronous extending can be achieved while overturning is achieved.

    本发明公开了一种用于汽车座椅腿托的同步翻转延伸机构,包括基座以及转动安装在基座上的旋转基体,旋转基体上滑动安装有驱动横杆和延伸板,其中,驱动横杆端部滑动配合有引导块,引导块相对于驱动横杆的滑动方向与驱动横杆相对于旋转基体的滑动方向在空间内垂直,引导块一侧转动连接在基座上,并且引导块的转动中心相对于旋转基体的转动中心偏心设置,旋转基体转动,能够通过引导块带动驱动横杆在旋转基体上滑动。有益效果是:通过偏心设置的引导块,使得旋转基体在转动时,引导块能够受到偏心力,偏心力能够迫使驱动横杆在旋转基体上滑动,从而实现翻转的同时能够同步进行延伸。
