  • Publication number: 20120043740
    Abstract: Disclosed herein is a curtain airbag cushion. The cushion has a length appropriate for being deployed to the chest of a passenger. A blocking part which partitions the interior of the cushion into portions is oriented in the vertical direction. The lower end of the blocking part is spaced apart from the bottom of the cushion by a predetermined distance. Thus, when an inflator explodes, gas discharged from the inflator is guided towards the lower portion of the cushion and then guided towards the front or upper portion of the cushion through the space between the lower end of the blocking part and the bottom of the cushion.

  • Publication number: 20120038138
    Abstract: An airbag module for installation in a motor vehicle has an airbag made of an airbag fabric and folded up before being triggered by an inflation device. The airbag fabric has at least one slit forming an adaptive ventilation opening and a retaining strap, which at one end is held releasably on a retainer on the airbag module and at the other end is connected fixedly to the airbag. The slit (11) is cut into the airbag fabric and has two ends configured to prevent the slit (11) from tearing when pressure is applied. The retaining strap is arranged on the inside of the airbag and is guided through a securing loop (17) attached to the airbag fabric opposite the fixed end (14) of the retaining strap across the slit (11) toward the retainer.

  • Patent number: 8116948
    Abstract: An energy-absorbing force limiter for a safety device comprises a first component (5) and a second component (2), such as a seat-belt, that is moveable relative to the first component (5). The force limiter provides an energy-absorbing movement-resisting effect, for example by means of a frictional brake (4, 5), to resist movement of the second component relative to the first. An adjustable control element (6) actuates the brake. The magnitude of the frictional effect is a function of the degree of adjustment of the control element and at least one parameter, such as temperature, which influences the coefficient of friction. The control mechanism (9) adjusts the adjustable control element (6) to control the magnitude of the movement-resisting effect in response to a signal (12) representative of the desired resistance to movement together with a signal (10, 11) representative of that at least one parameter.

  • Publication number: 20120025502
    Abstract: A curtain airbag capable for preventing occupant ejection from a vehicle, particularly in the vicinity of a rearmost seat, while reducing the output required of an inflator associated with the airbag. The curtain airbag is stored at an upper position on a side surface portion of the occupant compartment of the vehicle, so as to be inflated and deployed along the side surface portion. The curtain airbag includes an inflation region and a wide portion in the form of non-inflatable cloth. The wide portion is attached to a rear edge portion of the inflation region and also attached to at least one point of the vehicle rearward of a front-side pillar, the front-side pillar being located forward of rearmost side window. The wide portion has a shape that allows it to be strained, by the inflated and deployed inflation region, into a generally planar configuration over an assumed strike area of the rearmost side window.

  • Patent number: 8087691
    Abstract: A steering wheel unit for a motor vehicle. The steering wheel unit has a steering wheel and an airbag module (30) located in the hub area of the steering wheel. This airbag module forms a housing (32), an airbag (52) folded into the housing, and a gas generator (54). The airbag module can be pushed down against the force of at least one spring element to activate a horn, whereby positioning means are present which define the position of the airbag module in relation to the steering wheel. In order to achieve a high degree of operational reliability and a very exact positioning of the airbag module in the steering wheel, at least one retaining means (28;38,68) is present which acts between the airbag module and the steering wheel (28;38,68). This retaining means is ineffective in the absence of outer forces and when the airbag module (30) is pressed down to activate a horn.
