A vehicle roll over protection system with at least one hoop member, longitudinal member, and connection device. The connection device couples the longitudinal member to the hoop member and includes first and second side plates that are fixedly attached on opposing sides of the hoop member in a substantially parallel arrangement to define a channel between the first and second side plates. Each side plate includes a cut-out that forms a cradle. The longitudinal member is received in the cradle. One or more wing plates are fixed to the longitudinal member. The wing plate(s) are received in the channel between the first and second side plates such that the first and second side plates act as displacement limiting features that limit the displacement of the longitudinal member relative to the hoop member in multiple directions.

A protection system for a motor vehicle having a sensor for determining an angle of inclination of the motor vehicle about its longitudinal axis. An airbag attached on an outside of the motor vehicle. A processing device designed to detect a risk that the motor vehicle may tip over, on the basis of the inclination angle determined, and in that case activates the airbag. The airbag can be pivoted in the vertical direction from an area close to the ground.

A method of controlling an active seatbelt includes checking whether a seatbelt is fastened, collecting driving information from a sensor or driving assist/safety system installed in a vehicle, determining a safety state of the vehicle based on the driving information, checking whether an airbag is deployed, and outputting a motor control signal for restraint control of the seatbelt in response to the safety state when the airbag is not deployed.

A modular vehicle seat is disclosed that includes one or more safety measures incorporated into the seat such that the seat can be pre-assembled in a modular unit that can be incorporated into a variety of vehicle designs. The safety measures may include an airbag deployment system that deploys an airbag from a seat back and extends around a shoulder portion of the occupant restraint system. The airbag deployment system includes an airbag that extends coaxially around the shoulder web of the restraint system of the vehicle seat. The safety measures may include a device for pre-tensioning a lap portion of an occupant restraint harness coupled to a seat portion of the vehicle seat. Illustratively, the pre-tensioning device may be activated just prior to activation of the airbag deployment system.

A vehicle configuration wherein the center of mass of the vehicle is approximately superimposed upon the passenger and driver centers of mass when seated within the vehicle. An occupant's center of mass can be approximated using a standard center of mass position approximation, or a combination of any number of standard center of mass position approximations. The vehicle's center of mass can be approximately superimposed upon the occupant's center of mass in at least the longitudinal and vertical directions.

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.

A vehicle window structure for preventing a person from being thrown out, applied to a vehicle, includes a fixing frame. An inner frame surface of the fixing frame is provided with a plurality of fixing portions spaced apart from each other. An arresting net includes at least one plastic rope fixedly connected to the fixing portions in an interlaced manner. The fixing frame is provided with a light-permeable unit that is mounted and fixed within the inner frame surface and covers the arresting net. When the vehicle has an accidental rollover unfortunately, even if the light-permeable unit is damaged or the fixing frame is deformed during the overturning of the vehicle, the arresting net is still able to arrest the user effectively because the arresting net is directly fixed to the fixing frame, thereby preventing the user from being thrown out of the vehicle.

A multiple pivot rollover protection structure includes a pair of primary pivot assemblies and a pair of shipping pivot assemblies. The primary pivot assemblies provide a plurality of different operating positions for the upper ROPS legs, and a generally vertical shipping configuration for the upper ROPS legs extending downwardly alongside and not behind a rear mounted engine. The shipping pivot assemblies provide a generally vertical operating position for each of the intermediate ROPS legs and a generally horizontal shipping configuration for each of the intermediate ROPS legs extending rearwardly alongside and not behind the rear mounted engine. A spring loaded plunger is engageable between each upper ROPS leg and intermediate ROPS leg. A latch may be provided between each of the upper ROPS legs and the intermediate ROPS legs to hold the spring loaded plunger in a disengaged position.

A vehicle safety device for detecting vehicle tilt automatically shuts-off power to an ignition system and fuel pump and summons emergency assistance using a bistable switch circuit that toggles between a first bistable switch position in response to a reset signal and a second bistable switch position in response to an alert signal. The safety device can remain in the bistable switch positions without a power source and employ an encrypted bi-directional protocol to summon emergency assistance and generate the reset signal without vehicle operator intervention.
