  • Patent number: 6722697
    Abstract: An assembly of seat belt buckle and a seat belt tightener has a seat belt buckle that is connected to a seat belt tightener by a pulling element. The pulling element is firmly connected within a buckle casing to a buckle mechanism of the belt buckle. The pulling element, in a region directly adjacent to the buckle casing is at least partly enclosed by a cover. The cover has an exterior shape that is tapered towards a direction in which the buckle is pulled during a seat belt tightening process. The external dimensions of the cover in the region of its larger cross section approximate the external dimensions of the adjacent end of the buckle casing and in the external dimensions of the cover in the region of its smaller cross section approximate to the external dimensions of the pulling element. Put another way, the taper of the cover approximates a taper defined by the external dimensions of an adjacent end of the buckle casing and the external dimensions of the cable over the length of the cover.

  • Patent number: 6688646
    Abstract: A vehicle seat belt system, in particular a three-point seat belt system, has belt webbing and an end fitting by which an end of the belt webbing is secured to a vehicle. A belt tensioner acts with a pulling eyebolt through which the belt webbing is guided by a webbing guide in the vicinity of the end fitting to transmit a tensioning movement to the belt webbing. The pulling eyebolt has a substantially straight pulling rod by which a pulling movement generated by the tensioning drive is transmitted to the belt webbing during tensioning and during tensioning the pulling rod acts as a webbing deflection rod for the belt webbing guided through the webbing guide. The webbing guide has two deflection points about which the belt webbing is guided during tensioning and the pulling rod acts on a section of the belt webbing guided between these two deflection points.

  • Patent number: 6357795
    Abstract: A seat belt buckle carrier unit free from rattling noises having a connecting element held in a specific place by a fixing device. The fixing device can be formed by a spring steel wire which is fixed at one end and with its free end, exerts pressure on the connecting element. To ensure reliable contact between the spring steel wire and the connecting element, the spring steel wire can have, at its end exerting a pressure on the connecting element, a loop that surrounds the connecting element.

  • Patent number: 6266855
    Abstract: A seat belt buckle has a guide channel formed in a buckle frame into which a tongue connected to a seat belt can be inserted. An ejector, located in the guide channel acts, as an ejector spring in the ejection direction opposite to the insertion direction of the tongue. A locking element is mounted on the buckle frame and can be moved out of an unlocking position into a locking position in order to lock the tongue in the guide channel. A securing element is movable between a securing position for holding the locking element in the locking position and a release position for releasing the locking element. A blocking device is mounted on the securing element and is moved into a blocking position when the locking element is in the locking position. The securing element is held in the securing position against a movement into the release position, whereby the blocking device is held in the blocking position by the ejector.
