SEAT COVER FOR MOTOR CARS

Abstract: The invention relates to the sector of seat covers for motor cars and envisages one or two plies consisting of a seamless meshwork formed by an upper portion (2) and a lower portion (3) with dimensions substantially corresponding to the dimensions of the backrest and the seat, respectively. The portions are surrounded by reinforced side strips (4). A reinforced central strip (5) is inserted, if necessary, between the portions (2) and (3) or a stitched strip (12) is arranged in the zone where the seat is joined to the backrest.

Description: 1 SEAT COVER FORMOTOR CARS TECHNICAL FIELD AND BACKGROUND ART. The present invention relates to a seat cover for motor cars. As is known, the practice of covering motor-car seats, with the aim of protecting the original seat upholstery and providing greater comfort during travel, has become widespread. For this purpose, in fact, cushions and back supports or matting which allow ventilation of the seat and the back in the zones against which the human body rests have been provided. Seat covers formed by central plies, to which lateral strips are stitched, have been provided, said lateral strips being designed to cover the front and side zones of the seat as well as the side edges of the backrest. In some seat covers the lateral strips are formed as one piece with the central plies made of fabric with a close-set weft and warp and stitched where necessary. In order to achieve more effective ventilation, it is necessary to ensure that at least the portion of the upper ply in contact with the human body is woven in a meshwork so as to achieve suitable ventilation which allows, especially during the summer season, but in any climatic conditions, the part of the body in contact therewith to be kept ventilated. DISCLOSURE OF INVENTION. The object of the seat cover according to present invention is that of allowing correct ventilation of the body, as well as ensuring perfect adherence of the seat cover also in the side, front and top zones, respectively, of the seat and the backrest without having to apply additional reinforcing strips which are sewn in the side zones of the backrest and the seat. Said objects are fully achieved by the seat cover for motor cars which is characterized by 2 the contents of the claims indicated below. BRIEF DESCRIPTION OF DRAWINGS. The characteristic features and advantages will appear more clearly from the following description of a preferred embodiment illustrated, purely by way of a non-limiting example of embodiment in the accompanying plates of drawings, in which: - Figure 1 shows a perspective view of a car seat to which the seat cover in question has been applied; - Figure 2 shows in schematic form a plan view of a meshwork ply for forming the seat cover according to the present invention; - Figure 3 shows a plan view of a meshwork ply according to a possible variation of embodiment; - Figure 4 shows a type of meshwork used for forming the ply in accordance with an example of embodiment; - Figure 5 shows a type of meshwork used for forming the ply according to a possible variation of embodiment; - Figure 6 shows another example of the seat cover. BEST MODE FOR CAJEtRYING OUT THE INVENTION. As shown in Figure 1, 10 denotes in its entirety a car seat to which a seat cover 11 has been applied, said seat cover 11 being formed by a first ply la which has an upper central portion 2 with transverse and longitudinal dimensions more or less corresponding to those of the backrest of the seat of a motor car. lb denotes a second ply which has a lower central portion 3 with longitudinal and transverse dimensions more or less corresponding to those of the seat of a motor car. In general, the transverse dimension of the two portions coincides, while the longitudinal dimension of the upper central portion is greater than the longitudinal dimension of the 3 lower portion. The two central portions la and lb are surrounded by a reinforced perimetral strip 4 woven simultaneously with the two central portions so as to be seamless. In the example shown in Figure 2, the ply, in the region of the end zone, does not have reinforcements, but a strip 12 is applied to it by means of stitching, said strip being designed to be inserted between seat and backrest during assembly of the seat cover. On the other hand, in the example according to Figure 3, 5 denotes a reinforced central strip which is made in a similar manner to the strip 4 and intended to divide the two portions and which coincides with the dividing zone between backrest and seat. The upper portion and lower portion and the reinforced strips are made as one seamless piece. The two central portions are made in the form of a meshwork, for example of the type illustrated in Figure 4, where the threads 8 of the meshwork are interlinked with the vertical chains 9, more precisely one chain for each thread of the meshwork. All the threads of the meshwork extend in the vertical direction, being interlinked with each other. The design of the meshwork is not altered with longitudinal tensioning of the meshwork itself, owing to the presence of the unextendable thread chain, while it can be deformed by transverse tensioning. The reinforced strips are woven simultaneously, covering the meshwork with other interlacing threads or with a vertical chain and transverse threads or with interlacing threads underneath the meshwork bound to the vertical chain. Depending on the shape of the various seats, the portion 2 or both the portions have four rounded reinforcing corners on the top side of the backrest and/or the front side of the seat. The perimetral strips 4 are positioned along the perimetral edges of the seat and elastic elements 6 provided with hooks 7 are connected to said strips in order to fasten and 4 tension the seat cover. A ply or a coloured fabric fixed to said plies by means of stitching or heat- welding may be advantageously provided underneath the plies la and lb in order to prevent dust from reaching the seat. The central meshwork portion of the ply 1 may be made according to the shape and size of the seat and/or the backrest of the motor vehicle. With reference to Figure 5, it is possible to note a thread 13 which joins together the chains passing in zig-zag fashion between two adjacent chains in the zone underneath the meshwork threads 8. Said thread 13 makes the ply less elastic in the transverse direction and acts as a weft thread. Figure 6 shows, according to a possible variation of embodiment, a reinforcement 14 which, in addition to covering the sides of the seat, also extends over the perimetral edge of the seat and the backrest by a few centimetres, so as to create a reinforcing zone also on the seat or on the backrest. The reinforcing strip is obtained using horizontal weft threads bound to the vertical chains or using weft threads packed closely together between adjacent warp chains. 15 denotes a piece of fabric stitched to the upper portion 2 and designed to cover partially the backrest of the seat. According to a possible variation of embodiment, the reinforcement could be provided only on the side zones of the backrest and the seat and not on the front zone of the seat or the top zone of the backrest.
