Head Rest: Testing and Inspection




Front Seat Active Head Restraint Inspection

NOTE: If the vehicle has been in a collision, always inspect the active head restraint, even if they appear reusable, by doing the following procedure.

1. Move the seat-back to the fully upright position. Raise the head restraint to the highest position.

2. Apply masking tape on the top of the head restraint.

3. Make marks (A) on both sides at 230 mm (9.06 in) upward from the roots of the head restraint frame (B) along the back of the head restraint (C) surface. Use the center point (D) between the two marks for the measurements in step 4.






4. Push the head restraint (A) forward, and measure the horizontal head restraint movement. The head restraint should move more than 50 mm (2.0 in) without resistance. If it is less than 50 mm (2.0 in), or the head restraint does not move smoothly, replace the seat frame assembly:
