  • Patent number: 7140571
    Abstract: An electric retractor extracts and retracts a seat belt in response to tension in the seat belt. The electric retractor may include a spool rotatably attached to a retractor frame. A seat belt is wound on the spool. The spool is rotated by a motor via a worm gear system that permits limited axial motion of the worm, but generally prevents the motor from being back-driven by tension in the seat belt to prevent forced seat belt extraction. The gear system may also cut off power to the motor in the event of excessive seat belt tension to prevent further payout of the seat belt. A senses tension in the seat belt and activates the motor to retract or extract the seat belt from the retractor. An emergency control system may override the web guide control in response to abnormal vehicle dynamics to provide reversible pre-crash pretensioning and/or crash pretensioning.

  • Patent number: 7083188
    Abstract: An airbag module may include an inflator, a cushion, and a retention apparatus that keeps the cushion in a stowed configuration until deployment. The retention apparatus may include a flexible member wrapped around the cushion and a hook-and-loop fastening strip attached to the flexible member via a sewn seam. The hook-and-loop fastening strip has hooks fastened to the flexible member to secure the flexible member around the cushion. The sewn seam is weak enough to permit the hook-and-loop fastening strip to break away from the flexible member. When the cushion begins to inflate, the sewn seam breaks to allow the hook-and-loop fastening strip to separate from one side of the flexible member while remaining attached to the opposite side. The cushion is able to inflate through the corresponding opening formed in the retention apparatus. In alternative embodiments, the flexible member, fastener, and attachment mechanism may be reconfigured or omitted.
