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.

A belt fitting for a safety belt device in a vehicle that includes a base segment and an insertion tongue connected thereto, in which base segment a belt eye is provided, through which a belt webbing is guided and divides the belt webbing into a shoulder belt segment and a lap belt segment when the safety belt is worn. The belt fitting has a clamping element movable between a release position, such that the belt webbing is freely movable in sliding contact over at least one belt running surface, and a clamping position, in which the belt webbing is tightly clamped between a clamping stop on the base segment and the clamping element in the event of a load or crash. The belt running surface of the belt fitting has a surface contour, which ensures stable transverse guidance of the belt webbing in the event of a load.

A locking apparatus used for controlling a movable chain, strip or strap-shaped object (71) comprising a support frame; a roll shaft (6) with a friction surface or a sprocket pitch slot (64), the roll shaft (6) being fixedly connected to a support rod (66), and one end of the support rod (66) being pivotally connected onto the support frame; a pawl (62) disposed above the roll shaft (6) and capable of rotating around one end; and a pressurization body (3) opposite to the roll shaft (6) along a transverse direction, thereby forming a roll gap between the roll shaft (6) and the pressurization body (3). The roll shaft (6) can freely rotate when the roll shaft (6) is in a middle state. When the roll shaft (6) is forced to downwards pivot until a ratchet disposed on a contact base (65) engages with a ratchet (6302) of the roll shaft (6) to prevent the rotation of the roll shaft (6), the object (71) can be locked. When the roll shaft (6) is forced upwards pivot until the ratchet (6302) of the roll shaft (6) abuts against the pawl (62), the roll shaft (6) can still rotate; when the object (71) changes the direction to downwards move, the pawl (62) engages with the ratchet (6302) of the roll shaft (6) to prevent the rotation of the roll shaft (6) and loses the engagement with the ratchet (6302) of the roll shaft (6) as the roll shaft (6) downwards pivots.

A tongue mechanism for use in an occupant restraint system also having a buckle mechanism and a webbing. The tongue mechanism includes a tongue member configured to selectively engage the buckle mechanism, a body formed over a portion of the tongue member, a slider, and a biasing member configured to laterally bias the slider. The body includes a body contact surface. The slider includes a slider contact surface and is configured to travel along a track between a first free position and a second locking position. When the slider is positioned in the first free position the tongue mechanism is free to slide along the length of the webbing, and when the slider is positioned in the second locking position a portion of the webbing is clamped between the slider contact surface and the body contact surface thereby preventing the tongue mechanism from sliding along the length of the webbing.

A plug-in tongue for a seatbelt includes a plug-in tongue component (10) and a clamping member (12) mounted thereto, wherein a belt guide passage (30) is delimited between the plug-in tongue component (10) and the clamping member (12), and the clamping member (12) comprises a center part (18) and two lateral parts (20) extending from the two ends of the center part (18) transversely to the latter. The plug-in tongue is characterized in that the center part (18) includes a central guide surface (32) located between the two lateral parts (20), and the two lateral parts (20) include lateral guide surfaces (34) facing each other, the guide surfaces (32, 34) constituting limitations of the belt guide passage (30).

In a buckle device, when a belt starts to be allowed to be drawn, a fracture portion is deformed by a side surface of a connection hole of a spool, so that the fracture portion allows a rotation of the spool and allows drawing of the belt. Then, the fracture portion is fractured by the side surface of the connection hole. Therefore, a drawing allowance load of the belt when the belt starts to be allowed to be drawn can be increased.

The invention relates to a belt deflector with a main element (100) that can be attached to the structure of a vehicle, and with a belt support element (200) that is movable relative to the main element (100) and forms a support surface (231) or support edge for a safety belt (20) to be deflected. According to the invention, the belt deflector comprises an intermediate element (300, 400) that is deformed when the movable belt support element (200) is moved relative to the main element (100), in the direction of the intermediate element (300, 400), and because of this deformation is pressed against the safety belt (20).
