Definitions

  • the invention relates to a cushion for a vehicle seat according to the preamble of claim 1.
  • a known upholstery of this type (DE 33 06 871 AI)
  • half-shells are inserted in the longitudinal grooves arranged in the seat and / or backrest area of the upholstery core, which are open to the outside and are connected on one side to a suction pump via a main connecting hose.
  • channels are provided in the upholstery core which penetrate the entire core thickness thereof. The channels are open on both sides and open out on the underside of the upholstery by passing through a seat shell of the vehicle seat that receives the upholstery.
  • the object of the invention is to further improve the seat climate with little additional manufacturing effort in the case of a cushion for a vehicle seat of the type mentioned at the beginning, a so-called full foam cushion.
  • the cushion according to the invention for a vehicle seat which has both a cushion for the seat part of the vehicle seat (seat cushion) and a cushion for the backrest (backrest cushion) has the advantage that the network of longitudinal and transverse grooves, which is connected to the room environment via the channels passing through the cushion core, results in very good moisture removal from the surface of the cushion core consisting of moisture-impermeable material.
  • the moisture that passes through the cover layer is transported to the mouths of the channels via the longitudinal and transverse grooves, and the visual moisture is released through the channels.
  • This passive Wegentfeuchtung a similarly good efficiency •, is achieved without additional measures and devices which can be reached only by means of active air extraction at 'the known pad.
  • Overall, a very good air permeability and moisture absorption capacity of the upholstery is achieved with a low-cost, low-profile full foam seat without having to resort to expensive spacer fabrics such as vehicle seats in the higher price range.
  • a fan is arranged to apply air to a central upholstery area.
  • This central fan which blows on the upholstery core from the outside, can accelerate the removal of moisture and thus maintain the comfortable seating climate even in extreme situations.
  • Active dehumidification is achieved according to an advantageous embodiment of the invention in that at least one shaft is completely penetrated in its core thickness in the cushion core, which is open to the outside of the cushion and in at least one of the longitudinal and / or Cross grooves opens.
  • An im A miniature fan arranged in the shaft which is preferably positioned by means of a grommet in the upholstery core, sucks in air from the upholstery environment and blows it into the network of longitudinal and transverse grooves, the air being discharged again via the channels in the upholstery. This very intensive air flow in the longitudinal and transverse grooves enables heat and moisture to be dissipated very quickly from the intermediate area of the upholstery delimited by the top layer and upholstery core.
  • FIG. 1 is a plan view of a seat cushion of a vehicle seat with a partially cut cover layer
  • FIG. 3 shows the same representation as in FIG. 1 of a modified seat cushion
  • a vehicle seat has a seat part and a backrest in a known manner, both of which are covered with a cushion. 1 and 2 only the seat cushion of the vehicle seat is shown, but the structure described below applies in the same way to the backrest cushion.
  • the pad consists of a pad core 11 made as a foam block and of a covering, air and moisture permeable cover layer 12, which in turn comprises a pad 13 made of reticulated foam and an air permeable cover 14 which clamps the pad 13 on the surface of the pad core 11.
  • the cover 14 is made of fabric or perforated leather. In individual cases the edition 13 can be replaced by a nonwoven or completely eliminated.
  • a heating mat for seat heating, which is not shown here, is usually also inserted in the support 13.
  • the pad 10 is in • the seat part to a seat pan or - which is clamped in a seat frame of the seat part received on a spring core 15 - as in the described embodiment.
  • longitudinal grooves 16 running in the longitudinal direction and transverse grooves 17 running in the transverse direction are introduced into the surface facing the cover layer 12.
  • Longitudinal and transverse grooves 16, 17 intersect and are open to the cover layer 12.
  • channels 18 open in the cushion core 11, which run through the cushion core 11 in the entire core thickness and open freely on the outside of the cushion core 11 facing away from the cover layer 12.
  • the longitudinal grooves 16, the transverse grooves 17 and the channels 18 are also molded in when the cushion core 11 is foamed.
  • the network of longitudinal grooves 16 and transverse grooves 17, in conjunction with the channels 18, ensures moisture transport of the sweat moisture produced by the seated person from the cover layer 12 to the outside of the cushion 10.
  • the longitudinal and transverse grooves 16, 17 are used to transport moisture to the sinks, in which the mouths of the channels 18 are located, and the moisture passes through the channels 18 into the open.
  • the cushion core of which is not itself permeable to moisture a comfortable seating climate is generated, as can only be achieved with high-quality seats with an expensive spacer fabric over the cushion core 11.
  • a ventilator 20 can also be arranged outside the upholstery (at the seat upholstery below) at a distance from the upholstery on the vehicle seat, which air is applied to a central area of the upholstery core 11.
  • This central fan 20 removes air from the pole blown into the channels 18 located in the central region of the cushion core 11.
  • This air enters the network of longitudinal grooves 16 and transverse grooves 17 and flows out again via the channels 18 present in the edge region of the cushion core 11 to the outside of the cushion.
  • the air flow is indicated by arrows in FIG. 2.
  • FIGS. 3 and 4 An alternative embodiment for active dehumidification of the full foam cushion is shown in the cushion for a vehicle seat shown in FIGS. 3 and 4.
  • the structure of the upholstery with upholstery core 11 and cover layer 12 and the longitudinal grooves 16, transverse grooves 17 and channels 18 introduced into the upholstery core 11 is unchanged and as described above for FIGS. 1 and 2.
  • the upholstery core 11 there are still two shafts 21 arranged at a distance from one another, which, like the channels 18, penetrate the upholstery core 11 in their entire core thickness and on the one hand at the crossing point of a longitudinal groove 16 and a transverse groove 17 and on the other hand freely on the outside of the upholstery core 11 open, but have a much larger clear diameter compared to the channels 18.
  • both shafts 21 are arranged in the center axis of the cushion core 11, one shaft 21 being located approximately centrally in the cushion core 11, while the other shaft 21 is displaced closer to the front edge of the cushion core 11.
  • a miniature fan 22 is arranged in each shaft 21 and is fixed in a known manner via a spout (not shown here) in the cushion core 11. Air is sucked in from the outside of the cushion by means of the two miniature fans 22 and pressed into the network of longitudinal grooves 16 and transverse grooves 17 via the shafts 21. There, the air absorbs the moisture and flows out again via the channels 18 on the outside of the cushion core 11.

Abstract

L'invention concerne un rembourrage comprenant un noyau, notamment en mousse synthétique, et une couche de protection perméable à l'air et à l'humidité, qui le recouvre. Afin d'améliorer le confort climatique par une bonne évacuation de l'humidité hors de la zone intermédiaire comprise entre la couche de protection et le noyau du rembourrage, il est prévu de façonner dans la surface du noyau de rembourrage recouverte par la couche de protection, des rainures longitudinales et transversales situées à distance les unes des autres, qui sont ouvertes en direction de la couche de protection et se croisent en sens inverse. Il est en outre prévu des canaux dans le noyau de rembourrage, qui traversent l'épaisseur du noyau dans sa totalité et débouchent, d'une part dans les points de jonction des rainures longitudinales et transversales et d'autre part, librement sur la face extérieure du noyau de rembourrage.
