I've developed, in conjunction with High Energy Sports Inc., a new style hang glider swing seat harness. After the first testing I made some changes and this video shows some flights with the new harness at Dockweiler Beach, CA.
In the early years of modern sport hang gliding basic swing seats were used for most of the flying. But as the sport advanced, the use of prone position harnesses became the standard method for pilot position in hang gliding. I always liked the seated position better and flew that way all through the 1970's. Now I'm working on a return to that original method with some modern designs for the seat itself and a set of aluminum bars to adapt the glider's control bar to the seated position in gliders already rigged for prone flying.
