Abstract
A panel body of an instrument panel in an automobile is formed of a synthetic resin foam. A duct element made of a synthetic resin foam having a compatibility with the panel body is welded to a back of the panel body to define air-conditioning air passages between the panel body and the duct element. Thus, the instrument panel also serves as a single duct element. Therefore, it is possible to provide an inexpensive air conditioning duct device in an automobile, which can be produced from a decreased number of parts and at a decreased number of assembling steps.
Claims2
An air conditioning duct device in an automobile, comprising:
- an instrument panel of the automobile formed by coating a synthetic resin skin on an outer surface of a panel body of the instrument panel, the panel body being made of a synthetic resin foam;
- and
- a duct element made of a synthetic resin foam having a compatibility with said panel body, said duct element being welded to a back of said panel body, thereby defining at least one air-conditioning air passage between said panel body and said duct element, wherein the compatibility of the synthetic resin foam of the panel body and the duct element, respectively, provides the at least one air-conditioning air passage with a desired heat-insulating property.
An air conditioning duct device in an automobile, comprising:
- an instrument panel of the automobile formed by coating a synthetic resin skin on an outer surface of a panel body of the instrument panel, the panel body being made of a synthetic resin foam;
- an upper duct element made of a synthetic resin foam having a compatibility with said panel body, said upper duct element being welded to a back of said panel body, thereby defining an upper air-conditioning air passage between said panel body and said upper duct element;
- and
- a lower duct element made of a synthetic resin foam having a compatibility with said upper duct element, said lower duct element being welded to a lower surface of said upper duct element to define a lower air-conditioning air passage between said upper duct element and said lower duct element, wherein the compatibility of the synthetic resin foam of the panel body and the upper duct element, respectively, provides the at least one air-conditioning air passage with a desired heat-insulating property.
