Patent

CA 2444641

An under carpet heat shield/floor pan insulator is provided for a vehicle. The shield/insulator includes an acoustical and thermal insulating layer of polymer fiber that shows no signs of any thickness increase, delamination, deterioration or any undesirable effect which may affect performance for at least 330 hours when maintained at a temperature of at least approximately 150°C (302°F). The shield/insulator may include a relatively high density, nonlaminate skin of polymer fiber and/or one or more facing layers constructed from polymer material.

Cette invention concerne un écran thermique sub-tapis de sol/isolant pour bac de plancher (10) de véhicule. L'ensemble écran/isolant comprend une couche d'isolation acoustique et thermique en fibre polymère (12) qui ne présente aucun signe d'augmentation d'épaisseur, de délamination, de détérioration ou autre effet indésirable pouvant compromettre les performances pendant si on le teste à une température d'au moins 150 DEG C (302 DEG F) environ pendant au moins 330 heures. L'ensemble écran/isolant peut comporter une couche de fibre de polymère (14) de relativement haute densité, non laminée et/ou une ou plusieurs couches se faisant face faites d'un matériau polymère (16, 20).
