Abstract: A safety arrangement in a motor vehicle includes a processor (1) which is associated with a central accelerometer (2) to provide an input signal indicative of the acceleration being experienced by the central part of the vehicle and also with at least one front sensor (3) adapted to provide an input signal to the processor in response to an impact at the front of the vehicle. The front sensor (3) is able to distinguish between differing degrees of severity of impact. The processor (1) controls at least one safety device such as an air-bag (6). The safety device has different modes of performance. The processor is adapted to activate the safety device in response to a predetermined signal generated by the central accelerometer (2) and is also adapted to select or control the mode of performance of the safety device in dependence upon the signal from the front sensor (3).

Abstract: A method for packing an inflatable airbag of a passenger restraint system of a motor vehicle into a housing, wherein the airbag includes a fabric envelope stored in a housing when not in use and is automatically inflated by a gas generator into a form of use when activated, includes the steps of firstly bringing the airbag into the form of use and secondly contacting the airbag in the form of use by mechanical folding aids and pushing the mechanical folding aids into the airbag. At least one first fold is formed so as to be arranged in a single fabric layer on the gas generator so that gas, produced by the gas generator for inflating the airbag when activated, directly impacts on the single fabric layer of the at least one first fold without flowing along other fold surfaces.
