Abstract: A tractor-trailer (10) comprises a tractor (12) and a trailer (14), a trailer coupling (12b) and a supply coupling (16/18) between the two component vehicles (12, 14) with a tractor-side coupling half (16) and a trailer-side coupling half (18), which can be coupled together by bringing them together along a predefined coupling axis (K). One of the coupling halves (16) is connected to the supply unit of the associated first component vehicle (12) through a flexible supply line (16d). To establish the coupled state between the two coupling halves (16, 18), an actuator (20) is arranged on the first component vehicle (12) that moves the first coupling half (16) toward the second coupling half (18) and joins the one to the other along the predefined coupling axis (K). The first coupling half (16) is arranged on the actuator (20) such that it can be oriented in all spatial directions at least within predetermined limits.

Abstract: In a webbing sensitive sensor, a rotatably mounted sensing pawl (14) is provided on a peripheral control cam surface (24) of a rotatable inertia mass (13) and is pressed by this surface into engagement with an internal tooth region. This peripheral control cam surface (24) has from a predetermined point an outwardly falling characteristic for reducing the torque exerted by the pawl on the inertia mass, so that the engagement motion between the pawl and the internal tooth region is effective independently of manufacturing tolerances.
