Upholstery fabric

摘要

A piece of upholstery fabric for covering three-dimensional supports such as vehicle seat bases and seat backs is machine-knitted, preferably in a mainly double jersey structure, with integral tubular portions. These serve as anchorage devices for securing the fabric piece to the support which it is to cover using rods or tapes which are threaded through the tubular portions. The tubular portions may be located at the margins of the fabric piece and also at intermediate positions where the fabric piece needs to be held down, for example in a depression in the support. They may project from a surface of the fabric piece and may be like loops or they may be in the form of tubular hems or a tube lying between front and rear faces of a double jersey structure.
