Abstract
A D-ring assembly comprising a D-ring and a load limiting device. The D-ring has a slot therethrough for receiving a seatbelt webbing and for guiding the webbing from the retractor to the torso of a vehicle occupant. The load limiting device functions by absorbing kinetic energy of the vehicle occupant during a crash to control the deceleration forces experienced by the vehicle occupant. The load limiting device has a deforming member partially embedded in a swivel ball. When a predetermined amount of force is applied on the D-ring assembly, the swivel ball rotates causing the deforming member to create a channel in the load-limiting device.
