Having worked in the safety restraint industry, automotive industry, and now being a car seat technician/instructor, I am impressed by the thoughtfulness of the design. That said, there are some issues of car seat testing and energy transfer that are overlooked. I agree with points cathwn raises. It would be interesting to see this design move forward in a formal manner. Fisher-Price had a design with a similar thought process in the late 90's. This is an innovative update to that design....

Unfortunately people are notorious for not using their restraints correctly (as you pointed out in your vid) so having an integral part of the harness so easy to not use is a possible design issue. Anyway, just wanted to say that you've come up with a brilliant design, I just wanted to give some feedback in case you were thinking about marketing this seat (which you really should!) to make it more user friendly.

If the seat is not able to tip backwards it can add stress to the neck. However, I'm sure if the test had been done with the ratchet at the same point as the Lower Anchors this cocooning would have occurred also. I like the seatbelt design but feel it has one flaw. The crotch portion would be too easy to not use. In a traditional harness the crotch strap is required when doing it up, whereas this design the harness is done up and then the crotch section is clipped over the belt...

Perhaps there would be a way of limiting the tightness achievable to avoid such a situation. I noticed in the crash testing of the ratchet that the belt went around the seat back and was attached to the base much higher than the Lower Anchors. This isn't a fair comparison as the different attachment point is what limited the seat movement. Also, the rebound (or cocooning) of the seat towards the back seat is actually part of the force absorbing action that helps limit stress on babies neck...

What a great concept! I love the idea of having a smaller section of the seat being released instead of just the whole seat! Do you think it would affect the safety of the seat in a crash situation? Have you come across the "Mighty Tight" from Sunchine Kids Products? It is a ratchet designed to tighten the belt install of a car seat. It's usually not recommended by CPSTs as it can make the install too tight and cause stress on either the belt or the plastic of the seat...
