An occupant protection device for a vehicle includes a seat, a three-point seatbelt device, and a belt airbag device. An occupant to board the vehicle is to sit on the seat. The three-point seatbelt device includes a seatbelt extendable across a front of an upper body of the occupant sitting on the seat. The belt airbag device includes a belt airbag that is provided at a shoulder belt section, which is extendable from a shoulder to a waist of the occupant, of the seatbelt, and that is configured to be deployed when a collision occurs. The belt airbag includes a belt-direction deployment section extendable and deployable along the shoulder belt section, and an intersecting-direction deployment section extendable and deployable in a direction intersecting the shoulder belt section. The sections are configured to form a single bag by being coupled to each other below a head of the occupant sitting on the seat.

The disclosure relates to a method for triggering an occupant protection device in a vehicle with a parking brake, wherein for the case in which a deceleration of the vehicle is demanded by operating the parking brake while travelling, the occupant protection device is triggered automatically and displaced from an initial position into a protective position.

An occupant protection device for a vehicle includes: a three-point seatbelt device having a seatbelt extendable across a front of an upper body of an occupant sitting on a seat; and a belt airbag device including a belt airbag that is provided at a shoulder belt section, which is extendable from a shoulder to a waist of the occupant, of the seatbelt the belt airbag being configured to be deployed when a collision occurs. The belt airbag includes a belt-direction deployment section extendable and deployable along the shoulder belt section, and an intersecting-direction deployment section extendable and deployable in a direction intersecting the shoulder belt section. The belt-direction deployment section and the intersecting-direction deployment section are configured to form a single bag by being coupled to each other below a head of the occupant sitting on the seat.

A method for activating a passenger protection device of a vehicle. A relative velocity value, which represents a relative velocity between the vehicle and an object, and at least one correction value are read in. In a further step, a velocity reduction value, which represents a decrease of a velocity of the vehicle when the vehicle collides with the object, is ascertained using the relative velocity value and the correction value. Finally, an activation signal for activating the passenger protection device is generated using the velocity reduction value.

A brake system having a wheel brake and being operable under a non-failure normal braking mode and a manual push-through mode. The system includes a master cylinder operable by a brake pedal during the manual push-through mode to provide fluid flow at an output for actuating the wheel brake. A first source of pressurized fluid provides fluid pressure for actuating the wheel brake under the normal braking mode. A second source of pressurized fluid generates brake actuating pressure for actuating the wheel brake under the manual push-through mode.

An information processing unit (32) collects accident information from a vehicle-mounted device (2) existing in a periphery of a site of an accident indicated by accident information stored in a storage unit (31), by controlling a communication unit (30).

An active seat belt control apparatus is controlled according to a state of a vehicle. A control method for the active seat belt control apparatus includes: collecting, by a communication unit, state information about the vehicle; determining, by a controller, whether to activate a pulling operation of a seat belt using the collected state information; and activating the pulling operation of the seat belt using a motor.

An occupant protection device for a vehicle includes: a three-point seatbelt device having a seatbelt extendable across a front of an upper body of an occupant sitting on a seat; and a belt airbag device including a belt airbag that is provided at a shoulder belt section, which is extendable from a shoulder to a waist of the occupant, of the seatbelt the belt airbag being configured to be deployed when a collision occurs. The belt airbag includes a belt-direction deployment section extendable and deployable along the shoulder belt section, and an intersecting-direction deployment section extendable and deployable in a direction intersecting the shoulder belt section. The belt-direction deployment section and the intersecting-direction deployment section are configured to form a single bag by being coupled to each other below a head of the occupant sitting on the seat.

A vehicle may include a vehicle detector configured to detect an obstacle and a condition of the inside and the outside of the vehicle; and a controller, when a front obstacle is detected by the vehicle detector, configured to determine a required braking distance or a time to collision (TTC) with respect to the obstacle, configured to determine whether a door side collision with the obstacle is estimated, when a collision with the obstacle is estimated according to the result of the determination, and configured to open a door in emergency or convert the door into a manual opening mode when the door side collision is estimated.

During a rollover situation there are possibilities of passenger head hitting the roof of the vehicle causing injury depending upon the passenger's height, head room, vertical and angular momentum where only side and curtain airbags cannot provide a complete head and neck protection. Comprehensive Roof Airbags (CRA) are integrated or installed internally and externally between, through and across the top of windshield, top of the roll over protection bars, head liner, roof rails, top of A, B and C pillars particularly works in roll over situation and deployed to cover the area with airbags on either one or more or combinations of inside headliner, outside rooftop and over the top of occupants head according to configurations and type of the vehicles thereby forming a protective layer to prevent or reduce the severity of head hitting the roof top in closed top vehicles and head hitting the road surface and debris in case open top vehicle ultimately to protect the passengers all to avoid or mitigate the head, neck and spine injury.
