Abstract: The invention relates to an elastic belt for furniture, articles or vehicle seats wherein a plurality of weft yarns are interconnected by bonding yarns. The weft yarns may include longitudinal double S configurations which allow the weft to lengthen and shorten following the elastic warp threads.

Abstract: The invention relates to an elastic belt for furniture articles or vehicle seats, wherein a plurality of weft yarns are interconnected by bonding yarns each with two elastic warp threads, preferably not adjacent warp threads. The weft yarns show longitudinal double S configurations allowing the weft to lengthen and shorten following the elastic warp threads. The invention further relates to a textile machine having elastic warp threads, a device for controlling the bonding yarns and a weft yarn guide with a plurality of passages for the plurality of weft yarns, the guide being acted upon to shift the weft yarns in both directions into alignment with two alternated warp threads, and to form the weft yarns double S configuration.

Abstract: In order to provide a springing effect in correspondence with the edge of a belt frame in chairs, sofas or the like, a device is envisaged consisting of a plurality of arms, each fixed to a belt and extending from the latter in inclined position, as well as a common transverse element connecting all the arms. Due to stresses on the latter element, the arms deform the belts which cause a bending moment of elastic return.
