Abstract: A guide that can be included as part of a pretensioner for a motor vehicle belt restraint system. The pretensioner includes a frame having walls that define an interior compartment. Located within the interior compartment is a piston assembly having a gas generator in communication with a piston. The gas generator creates an expanding gas that causes movement of the piston and applies tension to a seatbelt of the belt restraint system. The guide includes an opening through which the seatbelt passes and that causes the seatbelt to form a reduced width configuration upon exiting the guide.

Abstract: A seatbelt clamping device includes a U shaped housing configured for being mounted to vehicle structure and a shackle that is pivotally attached to the housing. The shackle can pivot between an open position for receiving a loop of seatbelt webbing and a closed position for retaining the seatbelt webbing. The housing includes a locking surface, and the shackle and locking surface define a gap therebetween through which the seatbelt webbing can slide. The shackle includes a shaft and a cam cover rotatable about the shaft. The cam cover includes an increased radius locking portion that can rotate toward the locking surface to clamp the seatbelt webbing in response to a load exerted thereon.
