Abstract: An apparatus and method for applying reference or grid markings to wallboard during the manufacturing process is disclosed. Reference or grid markings are applied to one sheet of cover paper at a location between the originating cover paper rolls and the cover paper creaser or creasers. This is accomplished by locating and aligning multiple print heads across the width of the continuously passing cover paper, such that markings are ejected onto the cover paper in a specific and coordinated fashion. In addition to using any suitable commercially-available computer equipment to coordinate printer head activity, this function is accomplished by attaching each print head to a common horizontal support element and provide individual adjustments that are perpendicular to, and with the directional flow of the passing cover paper.

Abstract: A dual spool seat belt retractor including a housing and lap and shoulder belt retractors mounted therein. An electric switch is provided for controlling an electric signal device, preferably used in conjunction with tension relieving means. The switch is preferably placed in its electrically conductive position in response to a predetermined number of revolutions of the lap belt retractor in the rewind direction.

Abstract: A dampening device is provided for a seat retractor associated with a passive seat belt system to reduce the rewind speed of the webbing in response to closing of a door of the vehicle. The dampening device is inoperable when the door is opened. The seat belt webbing may be maintained in a non-restraining position and automatically released to its restraining position under a slow rewind speed in response to a condition indicating that the vehicle is operable for locomotion. The dampening device may alternatively be actuated in response to a condition indicating that the vehicle is operable for locomotion.

Abstract: A passive seat belt system for a vehicle comprising a seat belt retractor mounted in the vehicle, seat belt webbing have one end attached to the retractor and another end attached to the vehicle, a thin elongated flexible element attached at one end to the vehicle and at a second end to a ring attached the webbing, and a button on the webbing for moving the ring and the webbing in response to motion of the vehicle door.

Abstract: A switch assembly is provided for use in sensing a seat belt spool condition in a seat belt retractor assembly. Features of the switch assembly are a switch housing in which is mounted a conductive member which forms both a fixed contact and a male terminal at its respective ends, a movable contact element which is supported for selective wiping contact with the fixed contact end of the conductive member, and actuating means which moves the movable contact element into wiping contact with the fixed contact end of the conductive member in response to a predetermined amount of seat belt webbing being stored on the spool of the seat belt retractor and which permits the movable contact element to move out of wiping contact in response to a predetermined amount of seat belt webbing being removed from the retractor.
