Notes from telecon with JSC’s Kiki Walters (X48856, B4S) and Glenn Johnson (39329, ISS trainer, B4N, glenn.f.johnson at jsc.nasa.gov)
12 July 2006
Glenn provided photos of the system and Kiki is sending drawings. He says there are at least 2 Russian bags onboard, maybe more.
Crews prefer them to STS bags because they are more detailed and have a cotton liner that can be changed out so they are better for long term use.
Russian company Centaur makes them.
Basically there are nomex straps on the ends that go to D rings in the sleep station or around handrails.
You zip yourself in. Optionally put arms out through slide slots. There is a neck hole, and a head area liner.
There are three large blue elastic straps that are optional, a crew preference item.
These are maybe 3 inches wide, and are used to provide force onto legs, hips and torso if desired.
JSC has one Class III bag that is used for training. Not sure there are straps in that training set.
Photo below shows the length of the sleeping bag
Photo below show the elastic straps - they are also 3" wide. They also tie-off on D-rings
Below shows the inside of the sleeping bag with a liner installed
Below shows how the liner is attached to the outer bag (velcro). They can be changed regularly.
