Patent DE-3418704-A1 (DE)
Title: Device for covering chair cushions
Inventor: GRAUFF WOLFGANG
IPC: B68G7/05
Filed: 1984-05-19
Abstract: Unupholstered chairs are often upholstered with a thin seat cushion which is fastened to the chair back with two holding loops. The filling opening in the cover is, as a result of the sewn-on holding loops, very narrow and the foam filling very thin. Therefore, during the covering process, the foam must be greatly reduced in size, but because of its low expansion force it cannot expand again by its own force in the cushion. The advantage of the invention lies in the fact that the foam is rolled together into a very small volume by means of four rotatable bars and, after drawing on the cover, is unrolled again. The previous pure manual work is consequently considerably reduced.
