Design for Adaptive Rear floor carpet for changing shapes and complex architecture 2019-28-0004

Floor carpets in vehicle find their use to hide the metal floor. It is primary designed to protect the floor of a vehicle from dirt, wear, BSR and salt corrosion. The paper presented here proposes an engineering solution for development of an adaptive carpet which can be commonly used across three variants. The three variants have different seating configurations and the mounting strategies are specifically designed to cater to the needs of the particular variant which requires the development of different rear carpets and underlay NVH felts. This requires heavy investment owing to the requirement of different tools. The paper demonstrates engineering one single Adaptive rear floor carpet meeting mounting requirement of all the three variants and also matching with the carryover front floor & carpet, door scuff plate, RQT and Rear Scuff plate. Single Underlay felt and single carpet is designed considering all three variants seat mounting configurations. It ensures easy identification of the carpet part in built shop and no compromise in the NVH perimeters from the underlay floor. Unique fixations identified for the carpet to accommodated in all three BIW floor panels, several design iterations has been made to freeze the adaptive carpet concept. One single underlay felt is executed, so that three variants of trimming options in one single carpet can be attained.
