摘要:
A noise reducing sound reproduction system and method is disclosed, in which an input signal is supplied to a loudspeaker by which it is acoustically radiated. The signal radiated by the loudspeaker is received by a microphone that is acoustically coupled to the loudspeaker via a secondary path and that provides a microphone output signal. The microphone output signal may be subtracted from a useful-signal to generate a filter input signal. The filter input signal may be filtered in an active noise reduction filter to generate an error signal. The useful-signal may be subtracted from the error signal to generate the loudspeaker input signal, and the useful-signal may be filtered by one or more low-pass filters prior to subtraction from the microphone output signal.

摘要:
A motor vehicle includes a body structure that has a lateral structure, a vehicle seat that is mounted on the body structure, and a side impact protection device for a passenger in the vehicle. The side impact protection device includes a head airbag with a first inflation device that can deploy upward in the region of the breastwork of the lateral structure, and a side airbag with a second inflation device that can deploy laterally out of the seat. In order for the side impact protection device to be used for different body structures, the side airbag is designed as a thorax airbag, which, in its ready state, is positioned, together with the second inflation device, inside the seat back of the vehicle seat, and can deploy essentially toward the front out of the side wall of the seat back. When the thorax airbag is in its deployed state, its upper edge comes to rest next to the breastwork of the lateral structure.

The invention relates to a vehicle with an airbag device covered by part of an interior fitting, comprising an airbag disposed behind the interior fitting part and a gas generator which is pyrotechnically connected to the airbag. A cord-type gas generator (20) is used as a gas generator and is disposed inside the airbag (18). The cord-type gas generator (20) is placed lengthways within a U-shaped recess in the interior fitting which opens upon inflation of the airbag device.

A safety system intended for an occupant of a motor vehicle is in the form of a protective bag which can be filled with gas. In a moved-in condition, the bag is folded together in a packet and, in an inflated condition, the bag extends along an interior side of a side window in order to protect a head region of an adjacent sitting occupant against an impact. To improve functioning of the safety device and reduce a space requirement, the packet is fully immersed in a door body of the door, and the protective bag unfolds during inflation from the door body, in a direction of a roof, essentially along the door window.
摘要:
An occupant impact protection system with an airbag that inflates when triggered whereby the protective effect of the inflated airbag is to be maintained beyond its service life. For this purpose it is provided that the airbag be foamable by means of particles introduced therein that are made of plastic that foam when activated and that are activated together with the introduction of the gas produced by the gas generator and a solid structure is formed for impact protection after the plastic foam hardens.
