Definitions

  • the mass bodies are force-transmitting engageable with the tensioner wheel and drive the belt retractor upon activation of the belt tensioner in the winding direction.
  • the tube is guided laterally with a first portion perpendicular to the longitudinal axis of the belt shaft of the belt tensioner on the tensioner, and directed with a second portion opposite the first portion tangentially to the tensioner.
  • the first portion and the second portion are arranged in a plane and connected to each other via a likewise arranged in the plane of the third section.

Due to the proposed attachment, the reaction forces arising during the activation of the belt tensioner are introduced more uniformly into the frame of the belt tensioner, resulting in lower maximum loads for the components involved as a result. Furthermore, the bending moments acting on the tube during the activation of the belt tensioner can thereby be reduced, since the tube is held against rotation on two holding sections.

  • the pot-shaped portion thus forms the central portion from which extend the portions of the other function outwards. This results in a total of a simple structural design with a very lightweight design.
  • the housing thus has with the cup-shaped portion practically a central portion from which the sections for the fulfillment of each other functions to the outside.
  • a particularly simple basic structure with a particularly stable support of the tube can be achieved by extending the holding portions of oppositely disposed portions of the edge surface and the guide portion of a located between the opposite portions portion of the edge surface of the cup-shaped portion to the outside.
