Locking tongue for a safety belt

摘要

A locking tongue (10) for a seat belt system has a base part (12), a webbing slot (16) in the base part (12) through which the belt webbing (44) can extend, and a locking cam (20) associated to the webbing slot (16) and supported at the base part (12). The locking cam (20) is movable between a rest position and a clamping position. A biasing means (26; 70) biases the locking cam (20) towards the rest position. The locking cam (20) can assume at least three positions, namely the rest position in which the belt webbing (44) can pass freely through the webbing slot (16), a clamping position in which the locking cam (20) presses the belt webbing (44) against the clamping edge (42) of the webbing slot (16) such that the belt webbing (44) is tightly clamped, the biasing means (26; 70) being able to return the locking cam (20) from the clamping position into the rest position, and a locking position in which the locking cam (20) locks the belt webbing (44) in the webbing slot (16), the biasing means (26; 70) not being able to return the locking cam (20) from the locking position towards the rest position.
