#CMT# #/CMT# The tensioner has a piston (10) arranged in a position before activation of the tensioner, where a free end (9) of a band (2) is set between the piston and a wall (5) of a cylinder (4) in the position. The piston is formed such that backward movement of the piston up to another position is enabled, where the free end of the band is not set between the piston and the wall in the latter position. The backward movement of the piston is caused by activation of a force limiting device. A bar (13) is provided at the wall of the cylinder. #CMT#USE : #/CMT# Belt tensioner for a safety belt device. #CMT#ADVANTAGE : #/CMT# The piston is formed such that backward movement of the piston up to the position is enabled, where the free end of the band is not set between the piston and the wall in the position, so that force-limited extension movement adjoining tensioning movement is not limited and belt withdrawal force acting on the tensioner is not increased. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a sectional view of a belt tensioner. 2 : Band 4 : Cylinder 5 : Wall 9 : Free end of band 10 : Piston 13 : Bar. |
