Definitions

  • the invention relates to a seat cover, formed in one piece from a permanently elastic material, with a base part and a front side and an opposite rear side.
  • This seat cover can be a separate part that is placed on a seat. However, this seat cover can also be integrated into a seat and then represents the upper layer of this seat and is arranged directly under the seat. Of course, this seat cover can be covered with a cover, etc.
  • a mattress or a pad which consists of several layers of flexible material.
  • the upper bearing is formed by a plurality of flexible ribs which project upwards from the mattress body and are arranged essentially parallel to one another.
  • the flexible ribs have flanks at their upper ends. From a trapezoidal central rib, flexible ribs and flank heads each slope towards the head or foot end of the mattress. Spaces are arranged between the individual ribs, the lateral ends of the mattress being closed off by a final bearing that is completely formed in one piece and covers all bearing layers. This final bearing serves as the last flexible rib and its flank as an attachment.
  • Such known seat covers generally serve to create a softer seat. This inevitably leads to the fact that ventilation, caused by loading and unloading processes, does not take place or only takes place to an insufficient extent, which then leads to sweating with the usual, highly undesirable phenomena. This could be remedied by making such seat cushions thicker, which in turn has the disadvantage of being unwieldy or resulting in an undesired seat height, which results in a lack of stability. In addition, the tendency to slide down, especially towards the front, is becoming increasingly apparent.
  • the invention has for its object to provide a seat cover that ensures a better and more comfortable sitting position and provides a practically fatigue-free sitting position. Furthermore, it is the object of the present invention to create a seat cover, the surface of which is adequately ventilated and ventilated in the event of load fluctuations.
  • the seat cover according to the invention shown in FIG. 1 is formed in one piece from a permanently elastic material with a specific weight of 40 to 100 kg / m3.
  • the seat cover is shown in the unloaded state and has a base part 1 with an approximately rectangular base. From FIG. 2 in particular it can be seen that five webs 2, 3, 4, 5, 6 projecting transversely to the direction of seat protrude upward from the base part.
  • the webs 2, 3 are arranged in the front area, the web 4 in the middle area and the webs 5, 6 in the rear area. These webs are arranged approximately parallel to one another and leave web spaces 12 between them.
  • the left side of the seat pad shown in the figures represents the front, while the right side represents the back.
  • the expression “seat direction” thus denotes the direction from the rear towards the front.
  • the webs 2, 3 are inclined towards the front and have laterally at their free ends projections 7, 8 which extend approximately horizontally towards the front.
  • the webs 4, 5, 6 are inclined towards the rear and also have projections 9, 10, 11 laterally at their free ends, which extend approximately horizontally, but in the direction of the rear. These projections partially cover the web spaces 12 and, together with the upper free ends, form a seat surface 13, as can be seen from FIG. 1.
  • the web 2 is laterally equipped at its upper free end with a tab-like extension 14 which is turned over to the bottom part 1 so that it is flush with the underside of the bottom part 1.
  • a tab-like extension 14 On the inside of this tab-like extension 14, a plurality of transverse support webs 15 are provided, which extend into the cavity formed by the folding.
  • the webs 2, 3, 4, 5, 6 deform in each case in the direction of inclination, the webs 2, 3 a force acting forward and the webs 4, 5, 6 a force directed backwards (towards the backrest) cause. This results in a force resultant which is directed backwards and opposes the user sliding downwards.
  • the oppositely directed pair of forces there is a certain tension in the garment of the user resting on the seat 13, which prevents creasing.
  • the projections 7, 8, 9, 10, 11, which partially cover the web spaces 12, together with the upper free ends of the webs provide a pleasant suspension and allow maximum ventilation when the load changes, i.e. ventilation of the seat cover and thus in particular of the seat surface 13 generated by loading and unloading, as a result of which the clothing lying on it, caused by the user sweating, is largely prevented.
  • the seat 13 slopes slightly backwards. In other words, the vertical height of the webs 3, 4, 5, 6 decreases slightly towards the rear end. This results in a better and more comfortable sitting position than can be achieved with known seat covers with a much greater backward slope.
  • ergonomic parts are formed which in turn also contribute to a better and practically fatigue-free sitting position.
  • a spacer bead 16 is arranged on the rear of the seat cover and runs parallel to the web 6, which prevents the web 6 from contacting one Hits the backrest and loses its effectiveness because it cannot deform backwards to the desired extent.
  • the webs 2, 3, 4, 5, 6 are provided with a groove-like depression 17 on their surface forming the seat surface 13, these depressions 17 running parallel to one another.
  • the front area with webs 2, 3 inclined towards the front preferably makes up 1/5 to 2/5 of the entire seating area.
  • the number of webs is of course variable and is not limited to the number specified in the exemplary embodiment.
