Definitions

  • the present invention relates to woven elastic belts used to support the human body in applications for articles of indoor or outdoor furniture, such as chairs, seats, settees, beds or other similar items, as well as for seats of motor vehicles and similar applications.
  • These belts are placed in tension between opposite sides of a frame of the article of furniture or the like and support, as stated, the weight and the thrust of the human body in place of more traditional springs.
  • Every belt is obtained from webbing with elastic warp threads in tension and substantially anelastic weft threads.
  • Every warp thread is in fact formed from a rubber thread, either natural latex or synthetic rubber, that it is covered with a substantially anelastic thread, for example a polypropylene thread.
  • the covering can be carried out by various methodologies, in themselves known, called respectively " chain stitch", “monospiral” or “bispiral”.
  • the chain stitch covering forms a plurality of knots, substantially equidistant, that limit the maximum elastic excursion of the complex formed by the elastic thread and the substantially anelastic covering thread.
  • the distance between two consecutive knots on the rubber thread, in conditions of maximum traction is usually comprised between some tenths of a millimeter and some millimeters.
  • the elastic belts with rubber threads have, exactly due to such rubber threads, an insufficient resistance to heat, ozone and to chemical agents in general. They tend to age and the rubber threads, with use, tend to tear and break, especially as a result of the tightening action exerted on them by the knots or the threads of the covering.
  • the object of the present invention is to propose an elastic belt of the type used for the cited applications which, while maintaining at least the same performance as the current elastic belts, avoids the disadvantages cited above.
  • This object is achieved, according to the invention, by replacing one or more of the rubber threads - preferably all the rubber threads - each with a thread or bundle of two or more polyurethane threads, especially threads in spandex.
  • the covering can be advantageously carried out with a covering having chain stitch knots that are closer to each other than those used in the covering on the rubber threads (up to + 80%) and this without danger of ruining the spandex threads.
  • the knots of the covering applied on the spandex are located with a gap thereof, under conditions of maximum traction, comprised between 1 mm and 9 mm.
  • the covered spandex threads are then arranged as the warp for the webbing of the belt according to classic methods.
  • the warp can also be placed under tension in this case, but it is possible in this way to exercise a tension close to the maximum that can be applied to the covered elastic threads of spandex, unlike what happens in the case of the rubber threads, where the tension must be limited in order not to excessively wear out the rubber.
