Harness Systems and Harness Fit Flashcards

Where should the harness chest clip (retainer clip) be positioned on a child in a car seat?

Answer: At armpit level

The chest clip must be positioned at armpit level to keep harness straps correctly aligned over the child's shoulders.

What is the 'pinch test' used to verify in a properly installed car seat?

Answer: No harness webbing can be pinched at the child's shoulder

If you cannot pinch any slack webbing horizontally at the child's shoulder, the harness is correctly tightened.

For a rear-facing car seat, the harness shoulder straps should be routed through slots positioned:

Answer: At or below the child's shoulders

Rear-facing harness straps must exit at or below the child's shoulders to properly restrain the body in a crash.

For a forward-facing car seat, harness shoulder straps should be routed through slots positioned:

Answer: At or above the child's shoulders

Forward-facing harness straps must be at or above the child's shoulders so they restrain the body during a frontal crash.

What is the primary function of the harness chest clip on a child restraint?

Answer: To keep harness straps properly positioned on the child's shoulders

The chest clip is a strap positioner only; it keeps shoulder straps from spreading too far apart but is not a crash-load bearing component.

Why is it unsafe to leave a child in a heavy winter coat while secured in a harness?

Answer: The coat compresses in a crash, creating dangerous harness slack

Bulky coats compress dramatically under crash forces, leaving the harness with slack that allows excessive child movement and reduces protection.

After placing a child in a car seat, what is the correct sequence for finalizing the harness?

Answer: Tighten harness using adjuster, then position chest clip at armpit level

Buckle and tighten the harness with the adjuster first, then position the chest clip at armpit level for accurate placement.
