Patent number: 6695344Abstract: An airbag module comprises an airbag and a front cover which is made of plastic. The front cover has a middle part and, surrounding the middle part, a predefined outlet opening for the airbag. In the closed state of said cover, the opening is surrounded by a ring-shaped part of the cover. The ring-shaped part is removed to free the outlet opening when the airbag is unfolded. The middle part is attached to the module in such a way that, when the airbag unfolds, the middle part is prevented from moving freely. The module further comprises a reinforcement ring which is embedded in the middle part and runs adjacent and along an inner edge of the ring-shaped part of the cover and attaches the middle part to the module, preventing it from moving freely when the airbag unfolds.Type: GrantFiled: July 31, 2002Date of Patent: February 24, 2004Assignee: TRW Automotive Safety Systems GmbH & Co.

Publication number: 20030228456Abstract: A leather covering piece for a vehicle interior lining comprises a leather piece and an intermediate layer connected with the leather piece. A hardenable mass is applied onto the intermediate layer or the leather piece. The hardened mass gives the leather covering piece such an inherent rigidity that it maintains a curved shape and can be inserted into an injection mold. The stacking of prefabricated leather covering pieces is also possible. The shape of the leather covering piece already corresponds to that of the finished product, in particular of the vehicle interior lining for which it is used. The leather covering piece is back-molded in order to obtain a stable carrier piece which gives the entire interior lining more stability.Type: ApplicationFiled: June 12, 2003Publication date: December 11, 2003Applicant: TRW Automotive Safety Systems GmbH & Co.
