Embodiment Construction

[0041] Referring to the drawings, in which like reference numerals refer to like parts throughout the several views, a seat belt assembly 30 includes a webbing guide 32 defining an aperture 34, a webbing 36 extending through the aperture 34, an airbag 38, and a clip 40 . The airbag 38 includes a fixed end 42 fixed relative to the webbing guide 32 and an inflatable end 44 inflatable along the webbing 36 away from the fixed end 42 . Clamp 40 is attached to inflatable end 44 and is movable from an unlocked position disengaged from webbing 36 to a locked position engaging webbing 36 .

[0042] In the event of a collision with the vehicle 48 , the airbag 38 distributes the arresting force of the webbing 36 over a larger area of ​​the occupant 46's body, which may reduce chest compressions and may reduce the likelihood of the occupant 46 being injured. During a vehicle crash, the webbing 36 of the seat belt assembly 30 may apply a force to the occupant 46 to counteract the momentum...

Description

technical field [0001] The invention relates to a safety air bag assembly of a safety belt. Background technique [0002] Vehicles, such as motor vehicles, may include seat belts for occupants. One arrangement of seat belts is the three-point harness: the webbing of the seat belt is secured around the occupant at three points. Specifically, the webbing may be attached below the mounting point and to one side of the occupant's hip, may be attached above the mounting point and to the same side of the occupant's shoulder, and may be fastened to the opposite side of the occupant's hip. The webbing may be divided into a shoulder strap that spans from one shoulder of the occupant to the opposite hip and a lap band that spans from one hip to the other. [0003] In the event of a collision, the webbing of the seat belt restrains the occupant against the impact of the occupant. While seat belts may reduce the likelihood of occupant injury caused by moving around the passenger comp...
