A running board for a passenger car or light truck is assembled from an upper molded thermoplastic section or component having a Class A automotive finish and a lower component or section having reinforcing ribs and mounting brackets. The upper section includes three layers: a paint film having a Class A automotive finish, a thin layer of thermoplastic polyolefin (TPO) and a thick layer of polypropylene. The lower section is homogeneous and may be a plastic such as TPO, polypropylene or high-density polyethylene (HDPE), for example, which may contain chopped, randomly oriented glass reinforcing fibers. The two sections are secured to one another about their peripheries by autogenous bonding.

L'invention concerne une barre de frottement destinée à une voiture ou une camionnette et assemblée à partir d'une section ou d'un composant thermoplastique moulé supérieur comprenant un fini automobile de classe A et d'un composant ou d'une section inférieur présentant des nervures de renfort et des pattes de montage. La section supérieure comprend trois couches: un film de peinture présentant un fini automobile de classe A, une couche mince de polyoléfine thermoplastique (TPO) et une couche épaisse de polypropylène. La section inférieure est homogène et peut être un plastique, tel que TPO, du polypropylène ou un polyéthylène à densité élevée (HDPE), par exemple, pouvant renfermer des fibres de renfort en verre en morceaux et à orientation aléatoire. Les deux sections sont fixées l'une sur l'autre autour des périphéries de celles-ci, au moyen d'un lien autogène.
