Abstract: A tightening device for a safety belt includes a cable having a first end and a second end. A drive is connected to the first end of the cable. The drive, when activated, moves the cable in a tightening direction. The second end of the cable is connected to a safety belt. A deflection device about which the cable is guided is provided. The deflection device has a rotatable eccentric pawl and a stop. The stop limits rotation of the eccentric pawl when rotated upon movement of the cable in the tightening direction and thus defines a deflection position of the eccentric pawl. The eccentric pawl has an elongate extension extending in a direction of the cable portion extending between the drive and a deflection location at the deflection device. The eccentric pawl has a deflection end guiding the cable at the deflection location. The eccentric pawl has an eccentric arc opposite the deflection end.

Abstract: An airbag includes two super-imposed layers of fabric which are inter-connected by a peripheral seam. One of the layers of fabric includes a central aperture to receive a gas generator. The two layers of fabric are inter-connected by a breakable seam which defines a rectangular or square region. The bag may be turned inside out. The rectangular seam thus effectively defines the exterior of the inverted bag, facilitating subsequent folding of the bag.

Abstract: A self-locking safety belt device has a housing and a reeling shaft rotatably mounted therein. A vehicle-sensitive control system including a control disc acts on a locking member for locking rotation of the reeling shaft when the vehicle sensitive control system is activated. A control device including a switching lever acts on the control disc such that in a release position the switching lever is disengaged from the control disc so that the control disc rotates freely with the reeling shaft. In a locking position the switching lever secures the control disc against rotation and initiates locking of the reeling shaft. The control device has first and second gear wheels with a switching cam. The first gear wheel is connected to the reeling shaft. The second gear wheel is spaced at a distance from the first gear wheel and is rotatably mounted at the housing. The control device also has a crown gear enclosing and meshing with the first and second gear wheels. The crown gear is slidably mounted at the housing.

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.
