Anonymous wrote:Here is a video of harness tightness. Are you referring to the harness chest clip as a latch? It is the chest clip. LATCH is an acronym for Lower Anchors and Tethers for CHildren. This a system to install the SEAT into the vehicle. Is this what your son is doing. -- uninstalling the seat from the vehicle? If so, you have two HUGE problems. He can't possibly undo the lower anchors unless he is completely out of his seat. If he is strapped in tightly and properly, he should not be able to undo the harness straps. The way you use the harness strap tightened means he would be be able to bend over enough to grab the harness strap tightened up AND PULL it out.
The harness should be tight enough that he is never able to bend that far forward. If you can't get the straps tight enough and he gets the chest clip undone, something is very,very wrong. The straps are not tight enough because when the are, the chest clip lies flat against his body and he shouldn't be able to pull it apart.
You need to learn how to tighten the straps or something may be not be working on the seat. Get to a real tech with your child in his seat to check this out. You may need a different seat.
If you have a burner email address to use, post it and I will try to find someone to help you. Your child risks ejection sitting in the seat this way.
Here is the video.
