Vehicle trim assembly for use with heating and cooling of a vehicle seat

The invention relates to a vehicle trim assembly for use with heating and cooling of a vehicle seat. A vehicle trim assembly comprises a foam bun, an electrically insulated top finish layer above thefoam bun, a thermal gradient assembly under the finish trim layer, and a thermal enhancement layer between the thermal gradient assembly and the finish trim layer. The thermal gradient assembly is adapted to generate a thermal gradient when receiving an electric current and has an electrically conductive top layer, an electrically conductive bottom layer, and a semiconductor layer having first andsecond semiconductor regions between the top and bottom layers. The thermal enhancement layer has a thermal conductivity adapted to direct thermal energy transfer between the thermal gradient assembly and the finish trim layer. 本申请涉及用于加热和冷却交通工具座椅的交通工具装饰组件。一种交通工具装饰组件包含泡沫块、在泡沫块上方的电绝缘顶部饰面装饰层、在饰面装饰层下方的热梯度组件、以及在热梯度组件和饰面装饰层之间的热增强层。热梯度组件适于在接收电流时产生热梯度，并且具有导电顶层、导电底层和在顶层和底层之间的半导体层，该半导体层具有第一半导体区域和第二半导体区域。热增强层具有适于在热梯度组件和饰面装饰层之间引导热能传递
