Passenger Airbag Hidden Seam Instrument Panel Dynamic Opening Through Utilization of Heat/Energy/Pressure Devices

被动约束的政府标准导致在1993年为大多数汽车引入了乘客侧安全气囊。TIP Engineering已经开始了大量的研发活动，以开发下一代最先进的乘客安全气囊(PAB)展开门，而不需要任何可见的切割线。这个概念被称为隐藏Seam部署门。一个成功的隐藏缝门功能的主要参数是皮肤背面的划痕。目前的技术只能通过机械手段来实现这一标准。TIP将通过使用热/能/压力烟火装置将皮肤割伤到皮肤背面。在安全气囊被发射的时候，同样的命令信号将启动烟火装置来点燃，沿着安全气囊开口的外围产生一条即时的切割线。目前正在考虑的烟火装置主要用于国防工业，作为爆炸装置的引爆器。我们建议对这些设备进行重大修改和重新开发，以应用于安全气囊门。预期的好处是以更低的成本提高安全性、保修性和明显的造型改进。

Passive restraint government standards have resulted in the introduction of passenger side airbags for most cars in 1993. TIP Engineering has initiated a significant amount of R&D activity in developing the next state of the art passenger airbags (PAB) deployment door without any visible cut lines. The concept is referred to as the hidden seam deployment door. The major parameter of a successful hidden seam door function is the scoring of the back surface of the skin. Present technology can only accomplish this criteria by mechanical means. TIP would cut the skin by the use of a heat/energy/pressure pyrotechnic) device to the back surface of the skin. At the time the airbag is fired, the same command signal would initiate the pyrotechnic device to ignite creating an instant cut line along the periphery of the airbag opening. The pyrotechnic devices presently being considered are used primarily in the defense industry as an initiator to an explosive device. We propose to significantly revise and redevelop these devices for application on the airbag door. The anticipated benefits are to improve safety, warranty, and obvious styling improvement at a reduced cost.
