Features for a vapor compression system configured to cool and/or heat (i.e. thermally condition) two or more distinct climate controlled vehicle interior components via a common thermal bus are disclosed. Some embodiments employ a single compressor. Some embodiments employ multiple compressors and/or thermal buses, each servicing components located within respective interior thermal zones of a vehicle, for example a front row seat zone, second and/or third row seat zones, and/or an overhead zone and/or a trunk zone.

Systems, assemblies and circuits are provided for combined heating and occupancy for vehicle seats wherein a plurality of conductors are arranged in a parallel circuit configuration with respect to each other and are attached to a seat mat. Each of the conductors is configured to generate heat in response to receiving an electrical current. Each of the conductors is configured to generate an electrical field in response to receiving an electrical signal and with the electrical field being recognizable for determining presence of an occupant on the seat. At least one bypass conductor is connected between two of the conductors to preserve heating and/or occupancy detection capabilities of the circuit in the event of breakage in any one or more of the conductors.

An electronic control unit for a heating device of a vehicle seat that includes: a printed circuit board on which one or more heat sources are arranged; a printed circuit board temperature sensor which is thermally coupled to at least one of the one or more heat sources on the printed circuit board; and at least one heating wire temperature sensor configured to be thermally coupled to a heating wire of the heating device; and a data processing device configured to determine a temperature of the heating wire based on temperature measured values of the printed circuit board temperature sensor and of the at least one heating wire temperature sensor.

Provided is a vehicle seat with a structure enabling a rockable moving piece to be disposed in a seat face in a well-fitting manner. A vehicle seat in which a rocking means having a drive mechanism and a moving piece for conveying rocking movement of the drive mechanism to a seated person is disposed in a through hole obtained by hollowing out a portion of a seat face of a seat cushion, wherein: a recess which is recessed in the thickness direction so as to surround the through hole is disposed in the seat face of the seat cushion; and the moving piece is shaped so that the bottom surface side follows the recess.

A seat system includes a seat bottom and a seat back at a rear of the seat bottom. A thermally controlled seat belt includes a lap portion and a shoulder portion. The thermally controlled seat belt can include a porous sleeve that is connected to a seat ventilation system or a vehicle ventilation system. The seat belt can alternatively or additionally include a heating fabric or thermoelectric elements.

A thermally conditioned seat includes a seat portion constructed from a first material which includes a seat support structure that has a central support region and adjacent side bolsters laterally spaced apart from one another a width. A recess is provided in the central support region and includes an aperture. A porous material is arranged in the recess against the first material. A second material is arranged against the first material and the porous material. A cover includes an air permeable layer and an aesthetic layer that provides an exterior seating surface. The air permeable layer is arranged against the second material and the aesthetic layer has perforations. A blower is associated with the seat portion and is in fluid communication with the aperture. The blower is configured to supply a fluid through the aperture to the porous material through the recess. The fluid is configured to pass from the porous material to the air permeable layer and out the perforations.

A seat module adapted to be attached to a seat having mechanical parts and electric devices for seat operation in a motor vehicle includes at least one operating cable for activating at least one device, and a module plate formed with a mounting feature for attaching to the seat and a retention feature for attaching the at least one operating cable. An end portion of the operating cable is temporarily stowed on the module plate in a pre-assembled state where the operating cable is attached to the module plate, and the end portion of the operating cable is connected to the electric devices and/or mechanical parts of the seat in an assembled state where the module plate with the retained operating cables is securely mounted to the seat.

A capacitive occupancy or proximity detector includes a heating circuit, an impedance measurement circuit connected to the heating element and a diagnostic circuit configured for determining integrity of the heater element. The heating circuit includes a heating element, a heating current source and a common mode choke having a first and a second winding, the heating element being connectable to the heating current source via the first and second windings. The diagnostic circuit includes at least one controllable switching element coupled across the second winding circuitry for injecting a DC current into a series connection formed by the first winding, the heating element and a parallel connection of the second winding and said at least one controllable switching element; and at least one detection circuit for detecting a voltage variation across the second winding.

A seat heater for a motor vehicle is shown and described. An electronic controller receives input signals from a manual switch controlling separate seat and seatback heating elements. One type of signal, such as that resulting from one depression of the switch, effects energizing of both seat and also seatback heating elements. A second type of signal, such as two depressions of the switch, effects energizing of only the seatback heating element. The input signals provide operating power to the electronic controller. Optionally, energizing of the seatback heating element may be stopped should any other pattern of switch operation occur. Optionally, energizing of only the seatback heating element may be indicated audibly, visibly, or both. Optionally, energizing of only the seatback heating element may be limited to a predetermined time interval.

A device for ventilating a vehicle seat having a cushion (12) which is resilient with respect to user contact and which is constructed to form a seat and/or back contact face (24) and which has an air flow channel (16, 17) which forms an air outlet (15) in the direction toward the seat or back contact face, an air-permeable covering unit (18) which is formed in order to at least partially cover the air outlet and which is preferably constructed so as to be rigid and/or grid-like, and a ventilator rotor (30) which is associated with the air flow channel and which is driven in an electro-motive manner and a ventilator unit (14) which has a ventilator housing (32) which at least partially radially surrounds the ventilator rotor, characterized in that the covering unit and the ventilator unit are fixed on or in the cushion with spacing from each other along the air flow channel and without direct connection of portions of the covering unit and the ventilator unit, and the ventilator housing has at the peripheral and/or outer side first fixing means (34; 32; 80) which are constructed in order to secure the ventilator unit in the air flow channel by engaging in and/or in order to cooperate with second fixing means (12; 70; 74) which are provided on or in an inner wall portion of the air flow channel.
