  • Publication number: 20210345734
    Abstract: A buckle tongue having a tongue body extending in an insertion direction and forms a belt slot that extends across the insertion direction and is provided for guiding a belt strap through it, and has a contact section in which the belt strap rests in a load position, and the contact section has several recesses that in the load position minimize slipping of the belt strap; and a blocking element movably arranged in the tongue body, wherein the strap can move through the belt slot in a pass-through position of the blocking element and is inhibited in its mobility by the blocking element in the load position by a tensile force introduced into the belt strap, wherein in the pass-through position, the blocking element is arranged between the strap and the contact section, so that the belt strap does not rest against the recesses in the pass-through position.

  • Patent number: 10843657
    Abstract: A seat belt buckle tongue (1) with a tongue body (3) extending in the direction of plug-in (2), in which a strap slot (4) is formed for the passage of a strap (5), and a deflection element (6) movably the tongue body (3), The strap (5), in an unloaded passage position of the deflection element (6), is movable through the strap slot (4), and is at least prevented from moving by the deflection element (6) in the loading position of the deflection element (6) induced by a tensile force to the strap (5). The deflection element (6) is movable from the passage position into the loading position with a constriction portion (18) along the contact surface (19) of the tongue body (3), so that the strap (5) in the loading position with a strap portion is flat in contact with both the contact surface (19) of the tongue body (3) and with the constriction portion (18) of the deflection element (6).

  • Patent number: 10442394
    Abstract: A belt tongue (1) having a tongue body (3) extending in an insertion direction (2), a clamping element (4) in the tongue body such that a belt strap (7) guided through a cavity (5) in the tongue body (3) and running through a gap (6) can be moved through the tongue body (3) in an unstressed free-running position and, in a stressed position brought about by a tensile force in the belt strap (7), is clamped on a clamping edge (8) of the cavity (5) by the clamping element (4) that is pivotally mounted in the tongue body (3). A pre-tensioning device exerts a retractive force on the clamping element (4), at least in the stressed position, the force being oriented in the direction of the free-running position of the clamping element (4). The pre-tensioning device is a torsion bar (13) that is non-rotatably secured in the tongue body (3) and non-rotatably connected to the clamping element (4).

  • Publication number: 20170297528
    Abstract: A belt tongue having a tongue body, a clamping element in the tongue body, a belt webbing guided through a cavity in the tongue body and running through a gap between the clamping element and the tongue body. The belt webbing can be moved though the tongue body in an unstressed position and, in a stressed position is brought about by a tensile force on the belt webbing, is clamped on a clamping edge of the cavity by the clamping element that is pivotally mounted in the tongue. Laterally to the clamping element, guide sections are arranged, between which the belt webbing runs, so that the belt webbing in the lateral region of the cavity does not go between the clamping element and the tongue body. The cavity forms cavities laterally from the clamping edge.

  • Publication number: 20100018343
    Abstract: A method is provided for producing a steering wheel for a vehicle, especially for a motor vehicle. The method according to one form of the invention comprises the following steps: producing a steering wheel frame having a hub base, a steering wheel rim and at least one spoke by providing a hub insert, injection-molding a plastic matrix around the hub insert to give the hub base, the hub base having a hollow shape forming the interior and reinforcing structures being arranged in the interior of the hub base, injection-molding and/or gas-assisted injection molding or water injection molding the at least one spoke and the steering wheel rim from the plastic matrix, the at least one spoke connecting the hub base to the steering wheel rim, and at least partially coating the steering wheel frame with a coating. The invention also relates to a steering wheel produced by this method.
