Safety arrangement for motor vehicles
View Patent ↗A vehicle seat arrangement having a motor vehicle seat, in which arrangement it is possible to control the kinematics of the motor vehicle seat and/or of a vehicle occupant situated thereon, in such a way that, in the event of a crash, there is as small a relative movement as possible between the vehicle occupant and the motor vehicle seat along the direction of the crash forces.
1. A safety arrangement for motor vehicles, comprising:
a seat for holding a vehicle occupant, wherein the arrangement is configured to control kinematics of the motor vehicle seat and/or of a vehicle occupant situated thereon, in the event of a crash having crash forces in the horizontal vehicular transverse axis direction tending to cause a relative movement between the motor vehicle seat and the vehicle occupant situated thereon in the direction of the crash forces, such that a damaging interaction between the vehicle occupant and the motor vehicle seat is reduced; and
an airbag configured to deploy into a position that separates the occupant from the seat back so that damaging interaction between the vehicle occupant and the seat is thereby reduced, and wherein the airbag is configured to move the occupant in a horizontal vehicle longitudinal axis direction away from the seat back.
2. The arrangement of claim 1 , wherein the airbag is stored in the seat back and deploys forwardly to separate the occupant from the seat back.
3. A safety arrangement for motor vehicles, comprising:
a seat for holding a vehicle occupant, wherein the arrangement is configured to control kinematics of the motor vehicle seat and/or of a vehicle occupant situated thereon, in the event of a crash having crash forces in the horizontal vehicular transverse axis direction causing a relative movement between the motor vehicle seat and the vehicle occupant situated thereon in the direction of the crash forces, such that a damaging interaction between the vehicle occupant and the motor vehicle seat is reduced,
wherein the arrangement includes an actuator to separate the vehicle occupant and vehicle seat only at vehicle seat area at risk of impact from crash forces, and the actuator is an airbag configured to deploy into a position that separates the occupant from the seat back so that damaging interaction between the vehicle occupant and the seat is thereby reduced, and wherein the airbag is configured to move the occupant in a horizontal vehicle longitudinal axis direction away from the seat back.
4. The arrangement of claim 3 , wherein the airbag is located in a backrest or side part of the vehicle seat.
5. The arrangement of claim 4 , wherein the airbag is positioned to inflate only on one side behind the vehicle occupant to tilt the occupant away from the area of vehicle seat at risk of impact from crash forces.
