Special bag shape protects occupants of convertibles

TRW has just unveiled its next generation Head Protection System for Convertibles which uses a new bag shape, is compatible with more vehicles and results in cost savings relative to its predecessor.

The HPSC II technology is fully integrated in the backrest bolster eliminating the need for an integrated head rest and thereby increasing its compatibility with a broader range of convertible vehicles and saving money. With 18 convertible model launches in Europe in 2010 alone, consumer demand for this type of car is growing.

As with the first generation product, the new design works together with a torso protection system and both can be tuned individually.

Dirk Schultz, global engineering director, Inflatable Restraint Systems, commented: "HPSC II is compact and comprises light weight component parts resulting in a lower mass module overall. Like the first generation HPSC, the second generation HPSC also takes into account different load cases and passenger sizes. This adaptability improves the airbags' position in relation to the occupant in the event of a side crash situation."
The device uses a light weight pyrotechnic gas inflator with a diameter of only 20mm.

The Company's first generation HPSC is currently in production with a major European vehicle manufacturer and the second generation of this innovative airbag module concept will be ready for vehicle launches in 2013.
