An enhanced overhead airbag assembly is provided. The overhead airbag assembly has an airbag module designed to be attached to the roof of a vehicle, rearward of the header. The airbag module is concealed from vehicle occupants via a headliner assembly that includes a headliner, header trim, central console, and sun visors. The header trim covers at least a portion of the header and overlaps the forward edge of the headliner on the passenger's side. The passenger's side headliner is shaped to form a deployment door to permit emergence of the inflating airbag cushion. The headliner is tethered to the roof via a frangible fastener so that the headliner does not interfere with inflation or strike the occupant.

An airbag module may include an inflator, a cushion, and a retention apparatus that keeps the cushion in a stowed configuration until deployment. The retention apparatus may include a flexible member wrapped around the cushion and a hook-and-loop fastening strip attached to the flexible member via a sewn seam. The hook-and-loop fastening strip has hooks fastened to the flexible member to secure the flexible member around the cushion. The sewn seam is weak enough to permit the hook-and-loop fastening strip to break away from the flexible member. When the cushion begins to inflate, the sewn seam breaks to allow the hook-and-loop fastening strip to separate from one side of the flexible member while remaining attached to the opposite side. The cushion is able to inflate through the corresponding opening formed in the retention apparatus. In alternative embodiments, the flexible member, fastener, and attachment mechanism may be reconfigured or omitted.

Four load sensors having an upper limit value in a detection range are mounted in a seat of a vehicle. The weight of an occupant sitting on the seat is detected as a total of outputs from the load sensors. When the detected weight of the occupant is equal or larger than a predetermined value, the deployment of the air bag is permitted, and when the detected weight of the occupant is smaller than the predetermined value, the deployment of the air bag is prohibited. When any one of the outputs from the plurality of load sensors is the upper limit value in the detection range, the deployment of the air bag is permitted irrespective of the detected weight of the occupant. Thus, even when the output from the load sensor has been modified to the upper limit value by a limiting process, so that the weight of the occupant is calculated as a value smaller than an actual weight to become smaller than the predetermined value, the air bag can be deployed reliably to restrain the occupant.
