Abstract
Official abstract text for this publication.
A multi-part air duct ( 10 ) for a motor vehicle has a lower foam part ( 11 ), an upper foam part ( 12 ), and lateral injection moldings ( 13, 14 ). The injection moldings ( 13, 14 ) connect the lower foam part ( 11 ) to the upper foam part ( 12 ) on both sides.
First claim
Opening claim text (preview).
What is claimed is: 1. An air duct for a motor vehicle, comprising: a lower foam part having spaced apart first and second side edges and first and second lower openings formed in the lower foam part at positions in proximity to the respective first and second side edges of the lower foam part; an upper foam part spaced from the lower foam part, the upper foam part having spaced apart first and second side edges and first and second upper openings formed in the upper foam part at positions in proximity to the respective first and second side edges of the upper foam part; a first lateral injection molding extending between areas of the lower and upper foam parts in proximity to the respective first side edges thereof, an upper end of the first lateral injection molding being formed with an upper snap hook that passes through the first upper opening of the upper foam part, and a lower end of the first lateral injection molding being formed with a lower snap hook that passes through the first lower opening of the lower foam part so that the upper and lower foam parts are tensioned elastically in position on the first lateral injection molding; and a second lateral injection molding extending between areas of the lower and upper foam parts in proximity to the respective second side edges thereof, an upper end of the second lateral injection molding being formed with an upper snap hook that passes through the second upper opening of the upper foam part, and a lower end of the second lateral injection molding being formed with a lower snap hook that passes through the second lower opening of the lower foam part so that the upper and lower foam parts are tensioned elastically in position on the second lateral injection molding. 2. The air duct of claim 1 , wherein the lower foam part comprises parallel film hinges enabling at least areas of the lower foam part to be rotated between a substantially planar orientation for transport and a non-planar orientation for assembly onto the first and second lateral injection moldings. 3. A motor vehicle, comprising a radiator, and the air duct of claim 1 . 4. The motor vehicle of claim 3 , wherein the upper foam part of the air duct has a bulge that bulges inwardly on the air duct and bears against an external surface of a radiator.
