Abstract: A sensor device includes i sensor elements of a first type and j additional sensor elements of a second type, the i sensor elements of the first type being connected in a circuitry (n×m) matrix array with n row conductors and m column conductors, where i, j, n and m are natural numbers other than zero and where 1?i?n*m. Each of the i sensor elements of the first type is connected between one of the n row conductors and one of the m column conductors and each of the j additional sensor elements of the second type is connected between two of the n row conductors.

Abstract: A combined sensor arid heating element includes a sensor mat having several active regions interconnected by flexible connection strips. The flexible connection strips each include two carrier foils laminated together having contact arrangements arranged in the active regions at the inside of the carrier foils. Each flexible connection strips further include a heat conductor directly applied to an outer side of one of the carrier foils.

Abstract: A foil style switching element includes a first carrier foil and a second carrier foil arranged at a certain distance from one another and a plurality of contact arrangement arranged between the first and the second carrier foils. The contact arrangements are arranged on the first and second carrier foils so that an electric contact between the contact arrangements is generated when the first and the second carrier foil are pressed together. A foil style luminescent screen unit applied on a side of the first carrier foil facing away from the second carrier foil, the luminescent screen unit includes a first electrode layer, a dielectric layer, a luminescent matter layer and a second electrode layer. The first electrode layer of the foil style luminescent screen unit is applied directly on the first carrier foil which faces away from the second carrier foil.

Abstract: A device for venting a gas bag made of a textile material includes at least one ignitable pyrotechnic charge which is associated with the gas bag in such a way that, when the pyrotechnic charge is ignited, at least one thread of the textile material is directly destroyed by the explosion of the pyrotechnic charge.
