I have never done this so take this FWIW.

Make two forms (one for the top and the other for the bottom), curved on one side and flat on the other, and glue plies together on the form in a vacuum bag. Using the same bottom form, or another one just like it, place the stock on the form and cut out the design with a scroll saw. Depending on the width of the chair backs and your scroll saw, you might need to make the backs as two separate pieces and join them together after sawing.

Now, maybe some knowledgeable people will jump in here and tell you the real way to do it. :D

I’d think it best to bend the wood first, then cut out the pieces with a jigsaw. Problem is, the back is too big for bending in one piece. If you took boards of maybe 6” width and sliced them into 1/8” veneers, then laid them side-by-side (going from top to bottom), glued the surface, then laid another stack on top (with the edges alternated from the first stack for strength), glued, another stack, etc. until you have your desired thickness, you could then press the works in a form like the one Art mentioned and get the blank made. A jigsaw or a hand saw would work well, but with care to keep inside the lines on both the inside and outside surfaces that you would then need to clean up by hand. It will be a time consuming process, and it would be a good idea to use slow drying glue unless you are experienced with this process.

Those look like coopered backs to me. Within some
limits you should be able to make the back in several
parts cut nearly to the profile you want. Glue together
using dowels to align the parts and then shape
by hand.

You may want to make the sections from thicker
flat stock, make the cutouts and exterior cuts
while still leaving flats to get your clamps on, then
glue it up. After, shape the inside with a curved
cutting tool like a scorp, and do the outside with
drawknife and hand planes.
