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 cell arrangement comprising a plurality of inflatable/deflatable cells arranged in a first series of successive cells, a plurality of inflatable/deflatable cells arranged in a second series of successive cells, the cells of a series of successive cells being substantially aligned along the main direction of extension of the series of successive cells, the first and second series being aligned such that the main direction of extension of the first series coincides with the main direction of extension of the second series, the first and second series being arranged such that two successive cells of the first series together cover 10-100% of a major surface area of a cell of the second series and wherein each of said two successive cells of the first series cover 5-95% of the major surface area of said cell of the second series.

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.
