Which Airlines Do Not Use Amsafe Seatbelts?

Fri Aug 09, 2013 5:34 am

For those who didn't know, almost all airlines use seat belts made by Amsafe. However, there are some exceptions. One notable exception is Southwest, who uses seat belts made by Davis Aircraft Products (easily identifiable by their short and wide trapezoid-shaped tongue).

Does anyone know of any other airlines who use non-Amsafe seatbelts?

Talking about these, and slightly off topic, I did notice on my recent easyjet flight that the label on the seat belts says its certified to a force of 3,000kgs

Wow. Given that I'm 160 pounds (or, pretending to be 160 pounds), that's a force of about 41 g's.

I think the design requirement is 19g, so that would be about right for a 350 pound person. I just hope he's not in the middle seat next to me.

Much heavier than that and I don't think he would make it out the door at home, so 3000 pounds is enough.

Going back to the original topic, I actually read somewhere that Alaska uses a different type of Amsafe seatbelt on some of their aircraft, which has a wider, more rounded tongue than what most airlines use.

Do aircraft seatbelts have a fixed lifespan after which they have to be replaced, or are they only replaced when they appear worn (or excessively dirty)?

Can the hardware parts (buckles and the parts that attach to the seat frame) be reused, with only the webbing replaced?

Not counting the airbag belts, AS uses three different styles of amsafe seat belt. One each for the -400, NG's and NG with Recaro's. I have no idea about how widespread the usage is amongst other airlines but the belt used on the -400 is the one with the wider rounded tongue.

They are on condition so they are inspected/cleaned at regular intervals and replaced/fixed as needed.

I looked up a couple of different stores that sell seatbelt extenders, they carry 2 types, one for everyone except Southwest, and one for Southwest.

Yes, I already mentioned WN in my OP. WN uses seatbelts made by Davis Aircraft Products.

It was always my impression that the airline is responsible for stocking seat-belt extensions on every aircraft. At my airline we have two or three on each aircraft.

Yeah, I don't even know if they are legal to use despite the vendor saying they are certified. This thread says no:

Basically, as weak as they look, they have to be certified to hold up to 2 tons IIRC (or 45Gs) The only problem with that is, the seatbelt will simply slice through the body if the impact is brutal enough.

Back to the topic. Dutch airline Transavia is another one who uses seat belts from Davis Aircraft Products.

A propo, similar discussion has been held here in Tech Ops a couple of years ago: Why So Few Seatbelt Manufacturers? (by Viscount724 Jan 10 2011 in Tech Ops)
