  • Patent number: 6786545
    Abstract: A wind protection device for an open motor vehicle includes a passenger cell that has at least one car seat with a backrest. There is on a level with the top area of the backrest at least one air outflow opening of an air supply system. Thereby, the head, shoulder and neck area of the seat occupant is impinged on with an air stream that can be regulated to avoid an undesired air draft. The air supply system has at least one sensor to measure a parameter value, whereby the air stream, issuing from the air outflow opening, is regulated as a function of the parameter value by way of a regulating unit.

  • Patent number: 6629725
    Abstract: A seat part for a vehicle seat having a seat cushion which is covered over by an air-permeable cushion cover, can be actively ventilated and on the top surface of which there are formed, by stitched-down seams, a central and a front level seat surface and two border beads which bound the level seat surfaces laterally. The seat having a heating mat which is arranged between the seat cushion and cushion cover and belongs to an electric seat heater. In order to ensure that the seat cushion has good through-ventilation and is dimensionally stable over a long period of time, the heating mat is perforated, and the perforations of the heating mat are designed to be considerably sparser in the region of the central level seat surface than in the region of the front level seat surface and the border beads.

  • Patent number: 6626488
    Abstract: A cushion for a motor vehicle seat includes a layer of ventilation fabric, through which air can flow, and miniature fans integrated into the cushion to blow air into the ventilation layer. The air is received in sleeves installed in ventilation channels which penetrate the cushion from a cushion bottom side and extend to an upper side of the ventilation layer. To achieve adequate cushion ventilation with low fan noise even when using thin fabric ventilation layers made of relatively hard material, the sleeves are closed on their upper end with a flange and are provided directly below the flange with oblong holes which extend in the circumferential direction and have a width measured in the axial direction which is equal to or less than the thickness of the layer of fabric.

  • Patent number: 6619737
    Abstract: A seat module intended for a vehicle seat is designed as a seat cushion or backrest and can be actively ventilated. The seat module includes a cushion which has a lower foam layer impermeable to air, a central air-guiding layer made from a knitted fabric, and an air-permeable upper foam layer. The cushion is covered with a cushion cover and is divided by tacking into a face area and two side areas, which extend in the longitudinal direction. A cushion carrier accommodates the cushion. To improve the quality of the module for sitting comfort and long-term stability while achieving low manufacturing costs, the air-guiding layer rests on the lower foam layer in the face area of the cushion and directly on the cushion carrier in the side area of the cushion.

  • Patent number: 6541737
    Abstract: A temperature detector for an air-conditioned vehicle seat with seat heating and/or seat ventilation is disclosed. To ensure accurate temperature measurement for regulation purposes close to the surface of the seat cushion while eliminating purely local temperature peaks, the temperature detector is provided with a flat, extended heat absorption surface, which is preferably formed by a thin, flexible layer of good thermal conductivity in which a temperature sensor in button or disc form is firmly embedded.
