Abstract
Official abstract text for this publication.
A drive arrangement ( 1 ) comprising an input ( 2 ) from a primary power source ( 5 ) and an auxiliary power source ( 7 ). The drive arrangement ( 1 ) incorporates a DC-DC converter ( 8 ) and a motor driver circuit ( 14 ). The motor driver circuit ( 14 ) is connected to a motor ( 18 ) in a motorized seat belt retractor. The drive arrangement ( 1 ) drives the motor ( 18 ) in the event of a crash situation. If the connection between the drive arrangement ( 1 ) and the primary power source ( 5 ) is lost then the drive arrangement ( 1 ) draws power from the auxiliary power source ( 7 ) to drive the motor ( 18 ). The auxiliary power source ( 7 ) can also assist the primary power source ( 5 ) by limiting the current drawn from the primary power source ( 5 ).
