AI Technical Summary
Existing car seats cannot achieve significant forward adjustment of the seat cushion after the backrest is fully folded, which affects the utilization of rear space.
The front support is driven to rotate by a screw motor, and the seat frame is adjusted forward through a slide rail and roller structure. Combined with the angle adjuster, the backrest angle is adjusted, allowing the seat cushion to move forward significantly.
Without affecting the design, the seat back can slide into the lower part of the dashboard when fully reclined, freeing up more rear space to meet the needs of movie viewing mode. The structure is reasonably designed, runs smoothly, and is easy to adjust.
