Embodiment Construction

[0041] exist Figures 1 to 4 A tongue 10 for a seat belt in a vehicle is shown in . The bolt 10 has an insertion section 12 , which can be inserted into and locked in the belt lock, and a deflection section 14 which is threaded onto a webbing 16 and can turn the webbing 16 steering (see Figures 5a to 5d ). The deflection section 14 has an injection-molded encapsulation 18 made of plastic, which completely surrounds the deflection section 14 .

[0042] as especially in figure 2 As can be seen in the figure, a webbing channel 20 through which the webbing 16 is guided, as well as a clamping element 22 , the function of which will be explained below, is provided on the deflection section 14 . The clamping element 22 is curved in cross section, circular in this embodiment, and has a clamping surface 24 facing the webbing channel 20 and a deflection surface 26 arranged at the opposite end. Projections 28 are provided laterally on the clamping element 22 , by means of which th...

Abstract

In a latch plate (10) for a safety belt, having a plug-in portion (12), which can be inserted into a buckle, and a deflection portion (14) for a belt webbing (16), wherein the deflection portion (14) has a belt-webbing channel (20) and a clamping element (22) for the belt webbing (16) and wherein the clamping element (22) is displaceable between a starting position, in which the belt webbing (16) is freely movable, and a blocking position, in which the clamping element (22) is displaced towards a wall (36) of the belt-webbing channel (20) such that the belt webbing (16) is clamped between the clamping element (22) and the wall (36) of the belt-webbing channel (20), wherein the clamping element (22) has a clamping surface (24) which clamps the belt webbing (16) against the wall (36) of the belt-webbing channel (20) in the blocking position, provision is made for the clamping element (22) to be guided along an arcuate guide path (40) which extends substantially perpendicularly to the wall (36) in the region of the blocking position, such that the clamping element (22) is moved towards the wall (36) with the clamping surface (24) in a substantially perpendicular manner in the blocking position. According to the invention, provision is also made of a method for producing such a latch plate (10), said method having the following features of: - providing a deflection portion (14), - positioning the clamping element (22) at the deflection portion (14), and - partially encapsulating the deflection portion (14) and the clamping element (22), wherein the clamping element (22) is fixed to the deflection portion (14).

Description

technical field [0001] The invention relates to a tongue for a seat belt, which has an insertion section for a webbing, which can be inserted into a seat belt lock, and a deflection section with a webbing channel and a deflection section for a webbing clamping element, and the clamping element can be moved between an initial position in which the webbing is freely movable, and a locking position in which the gripping element moves relative to the wall of the webbing channel in the locking position such that The webbing is clamped between the clamping element and the wall of the webbing channel, wherein the clamping element has a clamping surface which, in the locked position, clamps the webbing against the wall of the webbing channel. [0002] The invention also relates to a method for producing such a bolt. Background technique [0003] In a three-point seat belt, the tongue forms a turning point between a first section of the seat belt that restrains the pelvis of a vehic...
