Safety belt tensioner for motor vehicles

摘要

A safety belt tensioner for motor vehicles which is securable to the vehicle chassis (12) has an elongate drive device (11) which acts on a flexible draw element (13) displaceable in its longitudinal direction. The flexible draw element is guided from the guide device (11) via a deflection member (14) secured to the chassis to a belt lock part (15) and is attached there for the transmission of a tensile force. The deflection member (14) is simultaneously designed as the mounting element which secures the drive device (11) to the chassis (12).
