Abstract
A seatbelt retractor assembly () has a seatbelt retractor () and an actuator () for locking and unlocking the seatbelt retractor (). An inertial sensor mass () detects changes in vehicle speed. The mass () has a guide surface () for interacting with the actuator (). The guide surface () moves between an unlocking position in which the actuator () unlocks the seatbelt retractor () and a locking position in which the actuator () locks the seatbelt retractor (). The guide surface () has an inner profile portion () and at least an outer profile portion (). The actuator () is in contact with the inner profile portion () in the unlocking position while moving into contact with the outer profile portion () as the actuator () moves towards the locking position. The inner profile portion () causes a different acceleration of the actuator () than the outer profile portion ().
