System for actuating and locking an automobile sun visor

A sun visor actuation system comprising:

• an attachment apparatus configured to attach to an automobile structure;
• an arm member rotatably attached to the attachment apparatus;
• a body member attached to the arm member;
• an actuation system operable to both rotate the body member and prevent the rotation of the body member responsive to an indication of an imminent collision
• a controller operably connected to the actuation system and configured to:
• receive the indication of the imminent collision;
• determine a present angular position of the body member;
• upon determining the present angular position is in an angular range likely to cause injury to an occupant:
• determine a desired second angular position for the body member that is outside the angular range likely to cause an injury to the occupant;
• and
• operate the actuation member to rotate the body member from the present angular position to the desired second angular position;
• and
• upon determining the present angular position is in an angular range unlikely to cause injury to the occupant, operate the actuation member to prevent rotation of the body member.
