Problems solved by technology

These technologies lack design freedom because the geometry (e.g., the size of the heater) is too strongly related to the thermoelectric properties of the system

Embodiment Construction

[0027] Fabric electrodes and / or heating fabrics are integrated in the vehicle compartment, preferably sensors and / or heaters are attached from the back to eg driver seat, passenger seat, rear seat, steering wheel, door sides of the compartment, gear lever Wait for the surface.

[0028] The present invention discloses how to design and produce fabric electrodes for occupant detection or classification systems or heating fabrics or fabrics exhibiting mixed functionality, ie they can be used for both sensing and heating.

[0029]All the materials used to produce this fabric and to provide the electrical conductivity are characterized by only small changes in their relative properties when they are exposed to the environmental and mechanical stresses present during the lifetime of the vehicle. These materials therefore themselves need to be elastic, flexible, and to some extent chemically inert. Especially when mechanically stressed, after cyclic bending loads or after exposure t...

Abstract

A flexible heater and / or electrode comprises a woven textile material having a warp direction and a weft direction, said textile material comprising at least one region having a low electrical conductance and at least two regions having a high electrical conductance. The at least two regions of high electrical conductance are adjacent to said at least one region of low electrical conductance. At least one of said at least two regions of high electrical conductance is operatively connected to a connection terminal of said heater and / or electrode, said connection terminal for connecting said heater and / or electrode to an electronic control circuit.

Description

technical field [0001] The present invention generally relates to conductive fabrics that may be used for occupant sensing and / or heating, for example in vehicles. The invention relates more particularly to fabric-based electrode elements for occupant detection systems (ODS), occupant classification systems (OCS) and / or occupant heating to be integrated in dedicated surfaces in the passenger compartment of a vehicle . Background technique [0002] Today it is known to equip motor vehicles with comfort-related functional components such as heaters (for seat area heating, backrest heating, armrest heating, steering wheel heating, shift lever heating, or heating of other interior surface areas), or Safety-related components such as occupant detection or classification systems used to control secondary restraint systems such as airbags or seat belt pretensioners or other safety systems such as driver monitoring or vital sign monitoring . Seat heaters and occupant detection or...
