Abstract
Official abstract text for this publication.
A self-locking seat belt retractor has the following components: a locking device ( 9 ) which can be actuated in a vehicle-sensitive and/or in a belt webbing-sensitive manner, a belt shaft ( 1 ), and a two-stage load limiting device ( 13 ) located within the force flow between the locking device ( 9 ) and the belt shaft ( 1 ). The load limiting device ( 13 ) includes a first, high-load limiting element ( 3 ) and a second, low-load limiting element ( 2 ). The load limitation level can be switched from high to low during load limitation. A third load limiting element ( 14 ) parallel to the second load limiting element ( 2 ) between the locking device ( 9 ) and the belt shaft ( 1 ) is formed by at least two structural elements ( 10, 11, 12, 20 a, 20 b, 21 a - 21 g, 22 a - 22 g ), at least one of which is sheared off during the load limitation.
First claim
Opening claim text (preview).
The invention claimed is: 1. A self-locking seat belt retractor; comprising: a locking device which can be actuated in a vehicle-sensitive or in a belt webbing-sensitive manner, a belt shaft, upon which the belt webbing can be wound, a two-stage load limiting device operatively arranged between the locking device and the belt shaft, thereby creating a force flux between the locking device and the belt shaft for allowing a load-limited belt webbing extraction during a load limi…
