A seat heater, e.g. for a vehicle seat, comprises a heating element (10) for dissipating heat when a heating current flows across it and a temperature sensor (15) for providing a temperature signal indicative of the seat temperature. The seat heater comprises a common mode choke (16) with at least three windings. The heating element is connected in series between a first (16.1) and a second (16.2) thereof so as to be operatively connectable to a power source (12) via the common mode choke. The temperature sensor is connected to a third winding (16.3) of the at least three windings in such a way that the temperature signal may be received, e.g. by a temperature controller of the seat heater, via the third winding of the common mode choke.

A capacitive occupancy or proximity detector (10) comprises a heating circuit, an impedance measurement circuit (34, 36, 40) and a diagnostic circuit.

They are connected to each other through a mechanical connection element (5) which extends through the electrically non-conductive substrate (2), the electrically conductive element (3) and the layer (4) at the punctured region (6). The cross-sectional area of the electrically conductive element (3) at the location of the punctured region (6) is larger than the cross-sectional area of the electrically conductive element (3) outside the punctured region (6).

A seat heater includes a seating heater, a protection device of a non-resettable type, a base material, and a protecting heater. The protection device has a first surface and a second surface opposite to the first surface. The base material is a sheet having a first covering portion covering the first surface and a second covering portion covering the second surface, and is folded so that the first covering portion and the second covering portion face each other. The protecting heater heats the protection device. The protecting heater includes a pair of first heating portions and a second heating portion. The pair of first heating portions are formed as a meandered shape only on a surface, which faces the second covering portion, of the first covering portion. The second heating portion is disposed between the pair of first heating portions, and formed as a meandered shape both on the surface, which faces the second covering portion, of the first covering portion, and on a surface, which faces the first covering portion, of the second covering portion.

A heating device that includes at least one heating element, at least one electrode element, and a substrate on which the at least one electrode element and the at least one heating element are arranged. The at least one electrode element is arranged in a path and the at least one heating element is arranged in another path that is different than the path of the at least one electrode element. The path of the at least one electrode element intersects the path of the at least one heating element in at least one contact zone. The at least one electrode element and the at least one heating element in the at least one contact zone are electrically conductively connected to one another.

A heating apparatus for a vehicle includes: a heat-generating apparatus including a heat-generating portion generating heat and a heat-insulating portion positioned above the heat-generating portion and insulating the heat generated from the heat-generating portion; and a storage apparatus storing the heat-generating apparatus.

A massaging chair assembly includes a pad that is positionable on a seat in a vehicle. A plurality of massage units is each integrated into the pad and each of the massage units abuts the user when the user sits on the pad. Each of the massage units orbits about a central point when the massage units are turned on to massage the user. A heating element is integrated into the pad and the heating element heats the pad to warm the user when the user sits on the pad. A control unit is integrated into the pad and the control unit is in electrical communication with each of the massage units and the heating element. A remote control is provided and the remote control is in wireless communication with the control unit for controlling operational parameters of the massage units and the heating element.

A seat control device for a vehicle seat of a vehicle is disclosed. The seat control device comprises a first control element which controls an electric adjustment motor for electrically adjusting the vehicle seat and/or an electric heating device for electrically heating the vehicle seat, a fluid valve which controls a fluid flow for the pneumatic adjustment of the vehicle seat, a second control element which controls an operating state of the fluid valve, and a fluid pump which is fluidically connected to the fluid valve, wherein the first control element, the second control element, the fluid valve and the fluid pump are arranged on a common circuit board.

A climate controlled system comprising: a movable member disposed in a recess of a cushion and forming part of an occupant support surface with the cushion; a heater overlaying the cushion and the movable member, the heater including: a flexible substrate, a heating element, and an adhesive layer, wherein the flexible substrate includes adhesive on opposing longitudinal edge regions and the adhesive directly or indirectly connects the heater to the cushion; and wherein the adhesive layer anchors the heater as the flexible substrate stretches or moves with the movable member as the movable member moves.
