Claims20
An airbag module for an opening in a roof of a vehicle, the airbag module comprising:
- an expandable safety device attached to the vehicle at one end;
- a rod attached to the expandable safety device at the other opposing end;
- an actuation assembly configured to move the rod such that the expandable safety device covers the opening of the roof when deployed;
- and
- wherein the actuation assembly comprises:
- a first cable connected to one end of the rod and a cable anchor and second cable connected to another end of the rod and the cable anchor;
- a plurality of fixed pulleys and a plurality of movable pulleys, wherein the first and second cables are routed around the plurality of fixed and movable pulleys;
- and
- an actuator configured to pull the movable pulleys away from the fixed pulleys during a predetermined dynamic vehicle event in order to deploy the expandable safety device to cover the opening of the roof.

An airbag module for an opening in a roof of a vehicle, the airbag module comprising:
- an expandable safety device attached to the vehicle at one end;
- a first rod attached to the expandable safety device at the other opposing end;
- an actuation assembly configured to move the first rod such that the expandable safety device covers the opening of the roof when deployed;
- and
- wherein the actuation assembly comprises:
- a spool rod, wherein a spool is connected to the spool rod;
- a pretensioned coiled spring configured to bias the spool rod to rotate;
- a cable connected to the spool at one end and the spool rod at the other end;
- a pin configured to hold the spool rod to prevent rotation of the spool rod from the bias of the coiled spring;
- and
- a pin puller configured to pull the pin during a predetermined dynamic vehicle event in order to allow the spool rod to rotate and allow the spool to reel in the cable to deploy the expandable safety device to cover the opening of the roof
