Crash pads are used as an interior material installed in front of driver and passenger seats, in order to protect passengers at the time of collision due to a vehicle accident.

Korean car-maker Hyundai Motor Co has secured an Indian patent for an invention relating to a two-shot molding crash pad that is cost-effective. It is also said to be capable of maintaining a uniform interface between different types of materials, which in turn provides good design quality to the interior of the vehicle.

Crash pads are used as an interior material installed in front of driver and passenger seats, in order to protect passengers at the time of collision due to a vehicle accident.

Generally, crash pads are formed of foaming materials to achieve elastic cushion performance and impact-absorbing characteristics to a certain degree, while providing an aesthetically-enhanced surface condition.

The auto company claimed that the invention provides a system and method for the crash pad in which an additional cap is not attached to a passenger side air bag (PAB) door after the two-shot molding, and a material interface is maintained in uniform pattern. When conventional two-shot molding is used to form a crash pad, a groove is formed by a second resin feed line in the surface of the central portion of the PAB door. In order to improve the aesthetic appearance, a cap or trim piece is required to be used to conceal the groove, which makes the system more complicated.

However, the addition of such a cap to the PAB door makes it difficult to reduce the cost of the part, and the new invention overcomes the shortcomings in the convention two-shot molding crash pad, the company said in a patent document.

Hyundai filed the patent application in 2008 at the Delhi patent office and a hearing was offered to the company in January 2017, after which a patent was granted recently.
