Abstract
An energy management device (10) for connecting a length of belt webbing (16) with a vehicle portion (30) includes an elongate strap (50). The strap (50) has a fixed end portion (100) for connection with the vehicle portion (30), a free end portion (102), and an intermediate portion (110) extending between and interconnecting the fixed end portion and the free end portion. The device (10) has an unactuated condition in which force is transmitted from the belt webbing (16) to the vehicle portion (30) through the strap (50) between the fixed end portion (100) and a first point (116) on the strap which is on the intermediate portion (110) of the strap. Upon the application of a force greater than a predetermined force to the belt webbing (16), the device (10) moves an actuated condition in which force is transmitted between the fixed end portion (100) of the strap (50) and a second point (116a) on the strap which is farther from the fixed end portion than the first point (116).
