COVERING FOR MOTOR VEHICLE SEATS WITH DIELECTRICALLY WELDED LAMINAR FACINGS

Abstract: A covering for motor vehicle seats includes a soft support member (1) of dielectrically weldable cellular polyurethane, a sheet of natural or synthetic fabric (2) flame-bonded or glued to one face of the support member (1) and artificial leather or vinyl laminar facings (3) firmly bonded to predetermined areas of the fabric (2) by dielectric welding to the support member.

Description: Covering for motor vehicle seats atith lialectrically welded laminar facings. The present invention relates to motor vehicle seat coverings in general and has the object Or providing a particularly simple and practical c'overing which' has an agreeable aesthetic appearance. The covering according to the invention is characterised in that it includes a soft support member of dielectrically weldable celiular polyurethane, a sheet of natural or synthetic fabric flame-bonde'd or glued to one face of the support member and artificial leather or vinyl' laminar facings firmly bonded to predetermined areas of the fabric by di'electric welding to the support member. By virtue of this' characteristic, a covering is formed which is econom'ical' and compact and which has a sculptured surface which displays the aesthetic aspect of the applied facings. The technology for the application df such facings allows considerable advantages to be obtained both from the point of view of manufacture and use compared with conventional coverings in which the coating of strips of fabric for aesthetic purposes may be carried out solely by sewing or special treatment of the' itself to make it suitable for heat-sealing. Furthermore the use of polyurethane as the padding and welding element gives the cover good resilience which leads in use to more effective recovery from deformations than that obtainable with other weldable materials. Compared with conventional coverings, the covering according to the invention also has a considerably simpler structure and hence by definition is cheaper to manufacture. One embodiment of the invention will now be described with reference to the appended schematic drawing which illustrates a portion of covering for motor vehicle seats according to the invention in perspective. The covering illustrated in the drawing comprises a padding member 1 of dielectrically weldable cellular polyurethane, to one face of which is flame-bonded or glued a sheet of fabric 2. The fabric 2 may be of any natural or synthetic fibre and may possibly incorporate a strengthening reinforcement. The padding member 7 has thinner portions 7a in correspondence with which there are applied laminar facing strips 3 of vinyl or artificial leather material for the purposes of aesthetic embellishment of the covering. The thinner portions 7a may be pre-formed or alternatively formed at the moment of application of the laminar strips 3. The facings 3 which preferably have an arcuate raised profile are firmly bonded to the fabric 2 by dielectric welding to the padding member 1. The length of the facings 3 may be equal to that of the entire covering both longitudinally and transversely or may be less than this, in which case the facings would partially cover the covering. In order to improve the strength of the covering, a mesh or reinforcing fabric or the like may be applied to the face of the paddihg element 1 opposite the fabric 2.

Claims: CLAIMS 1. Covering for motor vehicle seats, characterised in that it includes a soft support member (1) of dielectrically weldable cellular polyurethane, a sheet of natural or synthetic fabric (2) flamebonded or glued to one face of the support member (1) and at least one artificial leather or vinyl laminar facing(3) firmly bonded to predetermined areas of the fabric (2) by dielectric welding to the support member (1). 2. Covering according to Claim 1, characterised in that the or each laminar facing (3) has a raised or relief profile.
