Safety restraint

A vehicle safety restraint seat belt incorporating a load limiting effect to allow a limited and controlled forward motion of the occupant after the retractor has locked to decrease the forces exerted by the belt on the occupant's torso. [0002] The webbing is attached to a structural part of the vehicle via a load limiting device, which comprises: a container defining a flow path for a fluid, an actuator arranged within the container and operable to act on the fluid, and a restriction in the flow path of the fluid, wherein the actuator is movable within the container under the action of load transmitted to the webbing from the vehicle occupant under extreme acceleration or deceleration conditions, to move the fluid through the restriction in the flow path thereby to dissipate a predetermined portion of the load on the webbing. A rotary paddle array, or forms of vane pumps or peristaltic pumps are used.
