Abstract
A side impact protection device for an occupant of a vehicle includes a housing fastened on the vehicle body side, a gas generator and an air bag. Within the air bag, a partition is provided which has a blocking effect for the gas flow emerging from the gas generator, and a main through-flow opening is formed on the partition. So that, in the inflated condition, the air bag takes up its ideal operating position, it is provided that, in its mounted position, the air bag is installed so that it is rotated with respect to the gas generator or to the housing, specifically in the opposite direction to the erection moment in effect in the air bag during the inflation thereof.
Claims13
A side impact protection device for a passenger of a vehicle, comprising:
- a housing, fastened in a side door of the vehicle,
- a gas generator held in the housing,
- an air bag which can be inflated by the gas generator, and
- a partition, providing a barrier effect for a gas flow emerging from the gas generator, provided within the air bag, said partition extending approximately parallel to a lower boundary edge of the airbag and including a main flow-through opening through which gas can flow,
- wherein the gas generator, connected with the air bag, extends along a longitudinal axis of the gas generator, and
- wherein the lower boundary edge of the air bag, in an unfolded mounted position, extends at an angle, which is not equal to zero, with respect to the longitudinal axis of the gas generator so that, during inflation, the air bag is rotatable, as a result of a torque generated by gas flow against the partition, through the angle in relation to the longitudinal axis into an inflated operating position providing ideal protection for the passenger, with the lower boundary edge of the air bag situated substantially parallel to said longitudinal axis of the gas generator.
