Automotive Multi-Angle Adjustable Seat Headrest Internal Frame Assembly
This assembly is a dedicated internal support frame engineered for independent forward and backward tilt angle headrest adjustment. Paired with hollow bent support rods and a metal adjustment locking base, it integrates sliding/swiveling lock mechanisms to add micro-positioning adjustments in the fore-aft direction on top of standard vertical elevation. Commonly used in front seats of mid-to-high-end passenger vehicles, it contours to varying neck curvatures, optimizes head support contact points, mitigates whiplash injuries during rear-end collisions, and enhances long-distance travel comfort.
