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 guide loop for a seat belt in motor vehicles, comprising a one-piece metal body a cladding part and a displacement body. The metal body includes a fixing eye and a belt guidance slit and a rounded running surface. The a cladding part is made of plastic and held onto the metal body, and the displacement body limits the slit height of the belt guidance slit, through which webbing of the seat belt runs. The cladding part is formed as a one piece body with edge areas that at least partially enclose the metal body is firmly secured to the metal body by means of tension applied by the edge areas onto the metal body.

Guide loop element for seat belts with one-piece casting part

A guide loop for a safety belt on motor vehicles, including a guide element provided with a guide slit for the safety belt, which is fixed to a vehicle by means of a fixing screw, and an adapter with a displacement body for limiting the slit width of the guide slit. The adapter is coupled to the inside of the fixing hole of the guide element and includes an opening penetrated by the fixing screw inserted through the fixing hole. The fixing hole of is formed by a boring, with a cross-section slightly larger than the external diameter of the screw in order to maximize the overlap between a bearing surface of the guide element and a head of the fixing screw. In addition, a number of grooves are distributed around the boring's circumference. When the adapter is mounted, the grooves accept fixing arms of the adapter.
