You want keep the lap belt free of twists and as flat as possible across the thighs. It is OK if the lap belt bunches some and it is not a safety issue but we do want it to stay in the clips so if it is coming out, here are a couple things that you can try:
- As odd as it may sound, you can loosen the belt just a bit to not put so much tension on it. By using the vest you have lowered and moved your child back several inches into the protected area of the seat space. The small amount of “slack” that you allow in the system by leaving it in a “neutral” tension versus pulling tight will not negatively affect crash performance.
- The goal is to have the seat belt pre-crash positioned on the lap and shoulder. It does not need to be “pushing down” on the child’s lap, just lying there is sufficient. I know this is a new feeling after so many years of using 5-point harness seats. Think of the vest more like you would a booster (only better). It is a seat belt positioning device with some added features.
If you are still having problems with the belt coming out of the clips, let us know. We can send a couple replacements of a firmer guide with an offset opening ASAP.
