Abstract:
The seat heater of the present invention comprises: a warming heater provided in a seat section of a seat; a warming heater provided in a back section; an overheating-prevention unit; and a heating unit that heats the overheating-prevention unit, the overheating-prevention unit being configured by a non-return type temperature switch. This configuration allows activating the non-return type overheating-prevention unit prior to reaching an unsafe event, and turns the warming heaters OFF reliably, whereby a seat heater with an aim of implementing both high output and safety can be provided.
Abstract:
There is disclosed a heater for an automotive vehicle or other article of manufacture. The heater typically includes a first conductive medium and a second conductive medium disposed upon a carrier. In a preferred embodiment, the first conductive medium includes a first section and a second section that are electrically connected by a second conductive medium. The second conductive medium preferably exhibits a positive thermal coefficient.
Abstract:
A heated seat (302) comprising: a cushion with one or more trench (30) areas; a heater (300) comprising: a carrier (2) with a periphery, the carrier (2) further including: a first electrically functional layer (4) that is made of a conductive material that substantially circumscribes at least a portion of the carrier (2); and a second electrically functional layer (8) that is made of a resistive material; one or more electrical conductors {12} attached to the first electrically functional layer; a trim layer (40) that covers the cushion when the heater is placed over the cushion, and wherein the periphery includes a first side edge (18) and a second side edge (20), and each side edge includes a cutout (26), and the cutouts are located adjacent to each other—forming a neck portion (28); wherein the heater is attached to the cushion by placing an attachment device (32) over the neck portion (28) of the heater and securing one or both ends of the attachment, device (32) to the cushion so that the neck portion (28) is pulled Into the trench (30); wherein the neck portion (28) is free of the second electrically functional layer (6); and wherein the first electrically functional layer (4) and the second electrically functional layer (8} form a checkered pattern.
Abstract:
Embodiments related to moisture abatement during a heating operation of a climate control system are disclosed. In some embodiments, the climate control system includes a thermoelectric device (TED) or other thermal condition device having a hot side and a cold side. In certain embodiments, the thermal conditioning device is operated (e.g., by a processor or a condensate switch) to inhibit or prevent the occurrence of condensation, and/or to abate condensation that has already occurred, on the cold side of the thermal conditioning device during the heating operation.

Abstract:
A vehicle seat assembly includes a seating surface, wherein the seating surface defines a plurality of temperature controlled zones. At least one electrically actuated heating/cooling source provides one of heating and cooling to the plurality of zones. A controller individually controls electrical power supplied from the source to each zone and is operative to reduce power consumption in one zone relative to another zone in accordance with a predetermined profile designed to limit the overall power consumption of the assembly.
Abstract:
A method of controlling an electric heating system for a motor vehicle seat, in which a target time (tsoll) for a heating duration is varied as a function of a difference between a measured outside temperature (TA) and a measured inside temperature (TI). A control device for a heating mechanism (20) is also provided having an outside temperature (10) and an inside temperature sensor or seat temperature sensor (12), and having a control circuit for preassigning and/or varying a target time (tsoll) for a heat duration, as a function of a difference between a measured outside temperature (TA) and a measured inside or seat temperature (TI or TS).
Abstract:
The invention is a device for heating a seat (3) comprising a heating element (2) connected to a control unit (1) which is arranged to feed a current (I) through the heating element (2), a detector unit (6) in connection to the heating element (2) connected to the control unit (1) with current (I) being fed when the measured temperature value falls below a predetermined desired value (TB). The invention is characterized in that the detector unit (6) comprises at least one first temperature sensor (7) on or in the vicinity of the heating element (2) with at least one further temperature sensor (8) at a predetermined distance from the heating element (2). By means of the invention a more even heating of the seat is obtained with an increased comfort for a person sitting in the seat.
Abstract:
Described herein are methods for forming resistive heaters and force sensing elements on a flexible substrate, and devices that include these elements to provide a force responsive conductive heater, such as a seat heater in a vehicle. The methods include printing a conductive ink on a flexible substrate that is heated to 30° C. to 90° C. before and/or during the printing process and curing the substrate to produce a conductive pattern thereon. The conductive inks generally include a particle-fee metal-complex composition formulated from at least one metal complex and a solvent, and optionally, a conductive filler material.
