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.

Abstract: A vehicle seat comprises a seat bottom having a bottom cushion and a seat back coupled to the seat bottom with the seat back having a back cushion. At least one of the bottom cushion and the back cushion defines a passage. The vehicle seat further comprises a blower assembly coupled to one of the seat bottom and the seat back. The blower assembly comprises a housing and a stator, which is coupled to the housing and comprises a plurality of driving coils. The blower assembly further comprises a rotor rotatably coupled to the housing about a rotational axis, with the rotor comprising a plurality of permanent magnets arranged to generate a flux concentrated on the driving coils. The blower assembly further comprises an impeller coupled to the rotor to rotate about the rotational axis to generate a flow of air through the passage.

Abstract: Techniques are disclosed for controlling a plurality of components of a vehicle that are configured to emit heat when activated. A controller receives heat demand information about the activated components and determines from the heat demand information, an amount of power available for consumption by all of the activated components. The controller actively allocates power between the activated components according to the determined amount of power available such that an actual amount of power consumed by all of the activated components does not exceed the determined amount of power available.
