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 ().
