A belt tongue () having a tongue body () extending in an insertion direction (), forming a belt slot () for guiding a belt crosswise to an insertion direction (), and a blocking element (), movably arranged in the tongue body () The belt is movable through the belt slot () in an unloaded pass-through position of the blocking element () and its mobility is at least inhibited by the blocking element () in a loaded position, created by a tensile force introduced into the belt. The belt is deflected by the belt tongue () in the fastened state in a loop shape. A cover () is provided at least on one side of the tongue body () and is arranged having at least one partial section () under the belt slot (), and the partial section () directly adjoins the belt slot () and covers at least one part of the blocking element () in the pass-through position.

Belt tongue having a cover

A seat belt buckle tongue () with a tongue body () extending in the direction of plug-in (), in which a strap slot () is formed for the passage of a strap (), and a deflection element () movably the tongue body (), The strap (), in an unloaded passage position of the deflection element (), is movable through the strap slot (), and is at least prevented from moving by the deflection element () in the loading position of the deflection element () induced by a tensile force to the strap (). The deflection element () is movable from the passage position into the loading position with a constriction portion () along the contact surface () of the tongue body (), so that the strap () in the loading position with a strap portion is flat in contact with both the contact surface () of the tongue body () and with the constriction portion () of the deflection element (). In the loading position, the tongue body () engages with a region having the contact surface (), through at least the portion of the deflection element ().

Seat belt buckle tongue with a deflecting element

A belt tongue () having a tongue body () extending in an insertion direction (), a clamping element () in the tongue body such that a belt strap () guided through a cavity () in the tongue body () and running through a gap () can be moved through the tongue body () in an unstressed free-running position and, in a stressed position brought about by a tensile force in the belt strap (), is clamped on a clamping edge () of the cavity () by the clamping element () that is pivotally mounted in the tongue body (). A pre-tensioning device exerts a retractive force on the clamping element (), at least in the stressed position, the force being oriented in the direction of the free-running position of the clamping element (). The pre-tensioning device is a torsion bar () that is non-rotatably secured in the tongue body () and non-rotatably connected to the clamping element ().

Belt tongue comprising a torsion bar

A connecting element () for fixation of two half-shells () of a buckle cover () for a seat belt buckle. The connecting element () includes two externally profiled end-sections, an anchoring section () that is mounted to a first half-shell (), with a fastening section () adjoining a separation section (), The connecting element () is connected to the half-shell () in a material-bonded or interference-fit manner and the fastening section () is connected in a friction- and interference-fit manner to the additional half-shell (). The fastening section () includes a core plug () that tapers conically toward the free end, and having a symmetrically or asymmetrically formed ramp-shaped structure formed of single ramp-shaped sections () that widen respectively in the direction of the separation section ().

Connecting element for securing two half-shells of a belt buckle

Belt buckle (I) for a seat belt system. A cable () fastens the belt buckle () to a vehicle by a fastening device () riveted to the buckle housing (). The fastening device () having a plate-like base () from the base surface () with a contact projection () having a radial arcuate contact surface () for a loop () formed by the cable () protrudes. A pin () protrudes from the contact projection () which is offset eccentrically in relation to a vertex () of the arcuate contact surface () of the contact projection () around which the cable () wraps. A distance () of the vertex () of the contact surface () to a center () of the pin () is smaller than a radius of curvature () of the contact surface () at the vertex ().
