  • Publication number: 20040065763
    Abstract: The invention relates to a safety belt apparatus for vehicles, in particular motor vehicles having at least one safety belt (11), which is wound to a greater or lesser degree onto a belt reel (13) rotatably secured on the vehicle chassis (14) about an axis of rotation (12) and preferably biased by a spring retraction mechanism, in particular a spiral spring (15) in the belt winding up direction and/or having a belt draw out- blocking mechanism (26, 38; 55, 56, 57), which, with an attempted rapid draw out of the safety belt (11) and/or with in particular accident dependent accelerations and/or deviations of the vehicle position from the normal, horizontal arrangement of the vehicle blocks a further draw out of the safety belt (11), with a toothed ratchet wheel (29) being rotationally coupled to the belt reel (13) and cooperating with a blocking pawl (17) secured to the housing and movable into an out of engagement, in such a way that with the blocking pawl (17) moved into engagement with the toothed ratchet wh

  • Patent number: 6641077
    Abstract: A safety belt apparatus for vehicles, in particular motor vehicles having at least one safety belt, which is wound to a greater or lesser degree onto a belt reel rotatably secured on the vehicle chassis about an axis of rotation and preferably biased by a spring retraction mechanism. A toothed ratchet wheel is rotationally coupled to the belt reel and cooperating with a blocking pawl secured to the housing. The blocking pawl is movable into and out of engagement with respect to the toothed ratchet wheel by a cam ring concentric to the belt reel axis via a step down transmission. A toothed control wheel is connected to the belt reel via an eccentric transmission and has at its periphery a preferably wavelike arrangement of teeth which is surrounded by an inner toothed ring fixed to the housing of larger diameter and with complementary, but with a smaller or preferably larger number of teeth.

  • Patent number: 6250579
    Abstract: A belt winder for safety belts has a spindle (14) for the winding up of the safety belt (18) and a rotatable latching flange (12) which can be latched with respect to a fixed base frame (10). A torsion bar (16) is rotationally fixedly connected at its one end to the spindle (14) and is rotationally fixedly connected at its other end to the latching flange (12). A further torsion bar (26) is provided, which can be selectively switched in.

  • Patent number: 6113146
    Abstract: A roller guide assembly for a safety belt comprising a holder which can be secured to a vehicle part and which journals a guide roller between two bearings. In this, the bearings are formed resiliently. The invention prevents the bearings from prematurely wearing and avoids many of the high stress to which bearings in other roller guides are subjected.

  • Patent number: 5743480
    Abstract: The invention relates to a safety belt arrangement in vehicles having a belt tensioner comprising: a holder which is to be secured to the vehicle chassis, with a belt winding reel with a safety belt wound thereon being rotatably mounted on the holder; a belt retraction spring arrangement by means of which the safety belt is continuously lightly pretensioned in the draw-in direction so that it only loosely lies against the vehicle occupant secured by it; and an auxiliary drive which is separated drivewise by a clutch from the belt winding reel but is activated abruptly with an accident-dependent acceleration and is rotationally fixedly coupled to the belt winding reel via the then engaged clutch.

  • Patent number: 5553803
    Abstract: A belt tensioner for safety belt arrangements in motor vehicles has a holder (11) on which are provided a belt winding reel (12) with a safety belt (13) coiled thereon, a blocking arrangement and an additional drive (15) connected via clutch (20) to the belt winding reel (12). The additional drive (15) contains a pressure source (16) which abruptly builds up a high pressure in a pressure chamber on being triggered and also contains a torque generating device (18) acted on by the pressure in the pressure chamber (17) and a drive shaft (19) connected to the latter. The drive shaft (19) is rotationally fixedly connectable to the belt winding reel (12) via the clutch (20).
