Definitions

  • the invention relates to a protective cover for a seat with a seat and optionally with a backrest with a backrest, wherein the slipcover covers at least the area of the seat or the backrest that can be acted upon by a person using the seat and at least one membrane in this area consists.
  • Seat covers for seats in particular for vehicle seats, child seats and upholstered furniture for seating, are known.
  • Such seat covers generally have at least one or more areas which are acted upon by the person sitting on the seat during use.
  • conventional protective covers it is frequently observed that when the person sitting on the affected area transpires, especially in those areas of the body which act on said area, the perspiration evaporated by the person can not escape sufficiently. This is especially noticeable in the warm season for car seat covers or in offices for upholstered furniture to sit at the sitter as an uncomfortable sitting feeling noticeable.
  • WO 2004/096601 A1 discloses a motor vehicle seat with an air supply device, by means of which a ventilation layer of the upholstery of the seat for seat ventilation and / or seat heating can be flooded with an air flow, and with an air outlet opening of the air supply device arranged in the upper region of the seat the head, shoulder and neck region of the seat occupant can be acted upon by an air flow, wherein the air supply device is associated with a fan.

  • the membrane ensures that the protective cover in the area acted upon by the seated person evaporated transpiration in the direction of the seat is permeable. Transpiration can thus flow from the body of the seated person through the protective cover to the seat. In the reverse direction, the membrane is moisture impermeable. Thus, the fumes in the applied area, although in the direction of the seat in or under the slip cover but not again in the opposite direction from or flow under this.
