ABSTRACT:
The cover for a gas bag module comprises as its main part two layers of a fully vulcanized polyolefinic material, which are formed into a composite structure. This material consists of fully cross-linked rubber particles, which are distributed in a continuous matrix of thermoplastic material. The first layer is relatively hard with a hardness of approximately 32 to 43 Shore D and is essentially responsible for providing the desired structural strength. The second layer is relatively soft with a hardness of approximately 45 to 80 Shore A and ensures a pleasant, soft feeling when touched. It bears a coating of a two-component urethane lacquer system having a high scratch and abrasion resistance.
