Abstract
An occupant protection device for protecting a vehicle occupant in the event of a vehicle accident, with a gas generator and an airbag which is connected to the gas generator and is inflated by the gas generator in the event of an accident. The gas generator includes a combustion chamber with propellant material which is ignited by a releasable igniting charge, and both the gas formed during combustion of the igniting charge and the gas formed during combustion of the propellant material being used for filling the airbag.
Claims40
An occupant protection device for protecting a vehicle occupant in the event of a vehicle accident, comprising:
- a gas generator including a combustion chamber and a releasable igniting charge, wherein the combustion chamber does not contain any propellant material;
- and
- an airbag connected to the gas generator and configured to be inflated by the gas generator in the event of an accident,
- wherein only gas formed as a result of the igniting charge is used for filling the airbag.
An occupant protection device for protecting a vehicle occupant in the event of a vehicle accident, comprising:
- a gas generator;
- and
- an airbag connected to the gas generator and configured to be inflated by the gas generator in the event of an accident,
- wherein the gas generator includes a combustion chamber in which, in the event of an accident, a combustible material is combusted forming a gas which inflates the airbag,
- wherein the combustion chamber includes a space in which the gas formed by the combustible material collects before leaving the combustion chamber at a combustion chamber outlet, and
- wherein the volume of the space is larger than the volume of the combustible material.
An occupant protection device for protecting a vehicle occupant in the event of a vehicle accident, comprising:
- a gas generator including a tubular combustion chamber with first and second tube ends, the first tube end includes an electrically releasable igniter placed in a gastight manner and the second tube end includes a throttle element;
- and
- an airbag connected to the gas generator and inflated by the gas generator in the event of an accident,
- wherein a space between the igniter and the throttle element is filled exclusively with gas or air.
