Massage device for a vehicle seat
First Claim
1. A massage device for a vehicle seat having a seat cover, said massage device comprising:
- a linear sequence of inflatable massage cells arranged in succession and adapted to be disposed below the seat cover of the vehicle seat,supply lines and venting lines to and from the massage cells,a compressed air pump connected to the supply lines,a valve arrangement to selectively supply compressed air to the massage cells and to selectively vent the massage cells, anda control unit controlling the compressed air pump and the valve arrangement, wherein said control unit carries out massage functions by controlling the compressed air pump and the valve arrangement according to predetermined programs or programs set individually to selectively supply and vent the linear sequence of massage cells,wherein the massage cells are arranged in connected groups of adjacent massage cells with each group of adjacent massage cells being periodically inflated and vented as a unit,wherein the groups of adjacent massage cells are arranged in the linear sequence and are arranged so as to overlap with one another in a longitudinal direction such that, in each pair of first and second successive groups of adjacent massage cells, the first group of adjacent massage cells and the second group of adjacent massage cells are partially covering each other, andwherein the groups of adjacent massage cells are sequentially expanded for forming a wave effect below the seat cover of the vehicle seat, and during a portion of the wave effect an intermediate group of adjacent massage cells are inflated to a first degree to define an isolated bulging portion, a leading group of adjacent massage cells are simultaneously inflated to a second degree that is less than the first degree of the isolated bulging portion, and a trailing group of adjacent massage cells are simultaneously vented to a third degree that is less than the first degree of the isolated bulging portion.

Abstract
The present invention relates to a massage device for a vehicle seat including: a linear sequence of inflatable massage cells which may be arranged in succession below a of the vehicle seat, supply lines and venting lines to and from the massage cells, a compressed air pump connected to the supply lines, a valve arrangement for the selective supply of massage cells with compressed air and for the selective venting of massage cells and a control unit controlling the compressed air pump and the valve arrangement, and that the massage cells are designed such that in the inflated state they are wedge-shaped in cross section in a plane parallel to the longitudinal direction of the linear sequence of the massage cells, wherein the wedge shape of all of the massage cells in the linear sequence is oriented in the same direction.
