This utility model relates to the field of automotive seat technology, specifically to a front-row car backrest folding structure, including a base, a pulling component, a pushing component, a limiting block, a rotating block, and a backrest frame. When the backrest frame needs to be folded, the pulling component is pulled, which drives the pushing component to rotate. The pushing component pushes the limiting block to rotate away from the rotating block until the limiting block releases its restriction on the rotating block. At this point, the backrest frame can be pulled to rotate towards the base, folding the backrest frame. After folding, the limiting block returns to its original position, thus limiting the backrest frame. This utility model uses a cable-driven and rotating rod-linked mechanical structure to replace the traditional multi-link / hinge system, reducing the number of components by more than 40%. The overall structural thickness is reduced by 30%-50% compared to traditional designs, effectively avoiding encroachment on the legroom of the driver's cabin, thereby solving the problem of the large size and space occupation of existing front-row folding structures.
