Abstract: A massage device includes a linear series of inflatable massage cells, a common supply and venting line, an air pump, a controllable valve, a control unit, and a passive flow restrictor. The cells are arranged in succession and adapted to be disposed beneath a seat cover. The cells include a primary massage cell and a secondary massage cell arranged in a longitudinal direction. The line is in communication with the primary and secondary massage cells. The pump is connected to the line. The control unit is arranged for carrying out massage functions by controlling the compressed air pump and the valve according to a predetermined sequence set by a user for the controlled inflation and controlled venting of the linear massage cells. The flow restrictor interposes the line, and is spaced between the primary massage cell and the secondary massage cell.

Abstract: A massage system includes a common line, first and second restrictors for flow, an air pump, and first and second pairs of air cells. The line includes, and extends between, first and second portions. The line alternately flows supply and venting air. The first and second restrictors are in series along the line for controlling the alternating flow of the supply and venting air. The air pump provides the supply air, and is in communication with the second portion. The first pair of air cells is in communication with, and individually branches off from, the first portion. The second pair of air cells is in communication with, and individually branches off from, the line between the first and second portions. The second restrictor is disposed between the second pair of air cells and the pump, and the first restrictor is disposed between the first and second pair of air cells.

Abstract: A massage cell arrangement for a vehicle seat comprising a plurality of inflatable/deflatable fluid cells arranged in a series of successive fluid cells. The fluid cells are arranged to overlap with one another such that in each pair of successive cells a first cell and a second cell are partially covering each other. A portion of the fluid cells are multi-cells comprising at least two connected fluid cells comprising at least a base fluid cell and a top fluid cell, wherein internal spaces of the fluid cells of the multi-cell are in fluid communication with each other and the top fluid cell and the base fluid cell are arranged in such that the top fluid cell partially covers a major surface of the base fluid cell.

Abstract: According to one aspect of the disclosure, a massage device for a vehicle seat is provided. The message device includes a linear series of inflatable massage cells which are to be arranged in succession below a cover of a backrest or a seat body of the vehicle seat, supply and venting lines to and from the massage cells. A compressed air pump is connected to the supply inventing lines. A valve arrangement is provided for the selective supply of massage cells with compressed air and for the selective venting of massage cells. A control unit is provided for controlling the compressed air pump and the valve arrangement, said control unit being arranged for carrying out massage functions by controlling the compressed air pump and the valve arrangement according to a predetermined sequence set individually by the user for the selective inflation and venting of massage cells in the linear series.

Abstract: The present invention provides a massage system for a vehicle seat comprising a plurality of inflatable air cells arranged in a series of subsequent air cells, a supply line structure from and to each of the air cells, a pump for supplying air under pressure to the supply line structure, a control or switch unit for controlling the operation of the pump, venting means for venting the supply line structure, means for controlling air flow to and from the air cells to provide a sequential inflation/deflation along said series of air cells. The means for controlling air flow are provided by a plurality of flow restrictors having reduced flow cross-sections that are arranged in such a manner that between each pair of subsequent air cells a flow restrictor is disposed in the supply line structure.

Abstract: The invention relates to a seat construction comprising a seat cushion part and a backrest part, and: a presence sensor for detecting at least the presence of a person or an object placed in the said seat construction, means for ventilating the seat construction comprising at least one duct through the said presence sensor and at least one air passage through the rest of the seat construction, and a device for feeding an air current through the said air passage and through the said duct for ventilation of a predetermined region adjacent to the seat construction. According to the invention, the seat construction comprises a layer of an air-distributing material disposed between the said presence sensor and the said air-current-feeding device, whereby a flow path is provided for the said air current through the air passage, the duct, the said layer of air-distributing material and the said air-current-feeding device.

Abstract: The invention relates to an arrangement for ventilation of a vehicle seat, which arrangement comprises an air-distributing material and an electric heating element comprising at least one electrically conductive component arranged in a pattern in conjunction with at least one support, where the vehicle seat comprises a bottom part which is adapted for ventilation by blowing air in or sucking air out via at least one passage through the bottom part and on through the said air-distributing material. According to the invention, the said support, heating element and air-distributing material are manufactured as an integrated arrangement adapted for mounting in conjunction with the said vehicle seat, the said air-distributing material being designed as at least one unit which is dimensioned for mounting in a correspondingly designed cutout in the vehicle seat. By means of the invention, an improved arrangement for heating and ventilation of a seat in a vehicle is obtained.
