Abstract: An airbag device for a vehicle, including an airbag package, a receptacle, and a flexible protective covering for the airbag. The flexible protective covering includes at least two flexible, sheet-like protective elements secured to the receptacle. The flexible, sheet-like protective elements are connected to one another via at least one separable tearing line. The flexible, sheet-like protective elements flank the airbag during initial inflation and expansion of the airbag. A flexible guide layer is arranged between the protective covering and the airbag package. The flexible guide layer is permanently connected to a first of the sheet-like protective elements, such that the first sheet-like protective element, together with the guide layer, forms a composite layer flanking the airbag during inflation.

Abstract: One embodiment of the invention relates to an air bag module, in particular for a knee air bag. The air bag module includes an air bag housing, a air bag cushion, a tubular gas generator, a air bag cushion holding device, and a gas guiding device, to which the tubular gas generator is fastened. The gas guiding device is integrally formed with the air bag cushion holding device.

Abstract: An anti-lock braking method to retard the wheels of a vehicle provides thatbrake pressure be augmented or reduced or maintained constant in response to slip and/or the change in the rotational speed (positive or negative deceleration) of a retarded wheel as related to at least one threshold value, andthe respective renewed accelerations of the retarded wheels be measured during successive control cycles of the anti-lock braking so as to raise the threshold value or prevent a reduction of the brake pressure for a predetermined period of time in order to suppress undesired control operations which are releasable above all by oscillations of the vehicle axle.

Abstract: In a method of controlling the brake pressure of a vehicle brake system equipped with anti-lock protection it is provided to measure the slip and/or rotational retardation of a wheel whose brake is applied and to compare each measured value with a given threshold value so as to lower the brake pressure if the threshold value proves to have been surpassed. Undesired pressure reductions can be avoided by increasing the threshold value for given periods of time from a basic value (S.sub.G) and subsequently decreasing it again. At a point in time T.sub.1 at which the rotational retardation of the braked wheel is greater than a value corresponding to a physically feasible slowdown of the vehicle the threshold value is increased abruptly, to be decreased thereafter according to a predetermined function of time. During the lowering of the threshold value the change in speed of the retarded wheel is measured over given intervals of time .DELTA.T and compared with the instantaneous higher threshold value.
