Method and apparatus are disclosed for determining vehicle seat occupancy. An example vehicle includes a vehicle seat, an accelerometer coupled to the vehicle seat, and a restraint control module. The restraint control module is configured to determine a minute of arc measurement for the vehicle seat based on data received from the accelerometer, determine that the vehicle seat is occupied based on the minute of arc measurement, and provide an alert.

An occupant protection apparatus includes a seat arrangement determination unit that determines the arrangement of seats and a collision determination unit that determines information about collision occurring to a vehicle. A deployment control unit deploys an airbag when the direction of the seat and the direction of the seat determined by the scat arrangement determination unit (94) are opposed to each other, and the direction of the collision determined by the collision determination unit is on the front side of the seat, or on the front side of the seat.

An apparatus for helping to protect an occupant of a vehicle comprises an airbag inflatable from a stored condition to a deployed condition in which the airbag is positioned between a reaction surface of the vehicle and the occupant. The airbag comprises an upper portion and a lower portion. Each of the upper and lower portions is at least one of rolled and folded. The upper and lower portions are positioned overlying each other when in the stored condition. A deployment flap comprises a sheet of material having a first end portion and an oppositely disposed second end portion. The first end portion is secured to the vehicle. A portion of the deployment flap is positioned between the upper and lower portions. The deployment flap has a notch with opposite side edges converging in a direction toward the first end portion of the deployment flap and terminating at a vertex.

An occupant protecting device for a vehicle has a knee airbag that is disposed at a seat front side of a vehicle seat, and that, at a time of a front collision of a vehicle, deploys, and restrains leg portions of a vehicle occupant seated in the vehicle seat. A foot airbag is disposed at the seat front side of the vehicle seat. At a time of a front collision of the vehicle, when a seat front-rear direction position of the vehicle seat is disposed further toward a rear side than a predetermined position, the foot airbag deploys between the knee airbag and the leg portions of the vehicle occupant seated in the vehicle seat, and restrains the leg portions of the vehicle occupant seated in the vehicle seat.

An airbag assembly includes a housing and an airbag supported by the housing. A sheet includes a first end fixed relative to the housing and a second end. A reinforcement is elongated on the sheet. The sheet is deployable below the airbag with the second end free from the airbag.

The present disclosure relates to a method performed by an occupant protection system of a vehicle for supporting protection of a vehicle occupant in the event of an ongoing or imminent collision. The occupant protection system comprises an airbag panel arrangement arranged in connection with a dashboard of the vehicle, which airbag panel arrangement comprises an inflatable airbag adapted to upon deployment protect lower body parts of a vehicle occupant seated in a vehicle seat facing the dashboard. The occupant protection system determines a distance in a predeterminable direction between the airbag panel arrangement or the dashboard and the vehicle seat or an occupant seated in the vehicle seat; determines that the distance exceeds a predeterminable maximum threshold value; determines that one or more conditions for deployment of the airbag is fulfilled; and displaces the airbag panel arrangement outwardly from the dashboard by means of a panel displacing system.

A system includes an airbag including a first lobe, a second lobe, a first tether connected to the first lobe, and a second tether connected to the second lobe, a seat rotatable relative to the airbag from a first position to a second position, and a computer programmed to, based on whether the seat is in the first position or the second position, release one of the first tether or the second tether.

A recreational off-highway vehicle includes side-by-side passenger and driver seats held within a chassis that is approximately 50 inches wide. The seats sit low in the chassis and are covered by a roll cage. Grab handles are positioned on the sides of the passenger seat. Select large round tubing protects the vehicle, while rectangular tubing frames the portions of the vehicle beneath body panels. The vehicle is powered by an engine rearward of the seats that is connected to a transaxle. The engine and transaxle are isolation mounted together with a portion of the air intake assembly. The vehicle is suited for rough terrain travel.

Various embodiments of vehicle occupant safety systems having extendable restraints for use with, for example, airbags are described herein. In one embodiment, for example, the disclosed technology includes a 2-point occupant restraint that secures an occupant in an aircraft seat. In this embodiment, the aircraft seat is positioned in a seating area that includes a forward monument housing a stowed airbag. In the event of a crash or other significant dynamic event that causes, for example, a rapid deceleration of the aircraft above a preset magnitude, the airbag deploys between the occupant and the monument as the dynamic forces cause the occupant to pitch forward. The forward momentum of the occupant's body creates a significant tension load in the 2-point restraint, which causes the restraint to extend by a preset amount, thereby allowing the occupant to move forward in the seat more than the occupant would have moved had the occupant been wearing a conventional, non-extending 2-point restraint. Although the occupant is allowed to move forward, the occupant remains secured to the extended restraint by means of non-extending webbing that is secured around the waist of the occupant. Allowing the occupant to move forward in this manner enables the occupant's upper torso to impact the airbag at a reduced or otherwise more favorable angle. This can reduce both the speed and the angle at which the occupant's head impacts the airbag, thereby reducing the likelihood of injury.

An apparatus for helping to protect an occupant of a vehicle includes an airbag configured to be mounted to a support structure of the vehicle. The airbag is inflatable to deploy from a stored condition away from the support structure toward a vehicle seat in which the occupant is seated to one of a first deployed condition in which the airbag is configured for a non-reclined condition of the vehicle seat, and a second deployed condition in which the airbag is configured for a reclined condition of the vehicle seat. The airbag is configured to deploy to the first deployed condition in response to determining a non-reclined condition of the vehicle seat and to the second deployed condition in response to determining a reclined condition of the vehicle seat.
