Abstract
An embodiment occupant restraining apparatus includes a base to be fastened to a body of a vehicle, a support having a first end hinge-connected to the base and a second end configured to support a deployed airbag, and a bellows configured to be expanded by gas to pivot the support. During deployment of the airbag, the bellows is configured to receive the gas in concert with the deployment of the airbag.
Claims20
An occupant restraining apparatus comprising:
- a base to be fastened to a body of a vehicle;
- a support having a first end hinge-connected to the base and a second end configured to support a deployed airbag;
- and
- a bellows configured to be expanded by gas to pivot the support, wherein, during deployment of the airbag, the bellows is configured to receive the gas in concert with the deployment of the airbag;
- a gas cartridge fixedly disposed on the base and configured to store the gas for expanding the bellows;
- and
- an electric gas valve connecting the bellows and the gas cartridge and configured to allow the gas cartridge and the bellows to communicate with each other in response to detection of a collision of the vehicle, wherein the electric gas valve comprises:
- a body comprising a channel through which the gas cartridge and the bellows communicate with each other;
- an actuator configured to operate to open and close the channel;
- and
- a drive part configured to drive the actuator to open the channel in response to the detection of the collision of the vehicle.

A control system of an occupant restraining apparatus, the control system comprising:
- a collision sensor configured to detect a collision of a vehicle;
- and
- a controller configured to control, in response to detection of the collision of the vehicle by the collision sensor, an airbag to be deployed and simultaneously to operate an electric gas valve so that gas is supplied from a gas cartridge to a bellows that pivots a support supporting the airbag;
- wherein a base of the occupant restraining apparatus is fastened to a body of the vehicle;
- wherein the support has a first end hinge-connected to the base and a second end supporting the airbag;
- and
- wherein the gas cartridge is fixedly disposed on the base and is configured to store the gas for expanding the bellows;
- and
- wherein the electric gas valve connects the bellows and the gas cartridge and is configured to allow the gas cartridge and the bellows to communicate with each other in response to the detection of the collision of the vehicle;
- and
- wherein the electric gas valve comprises a body comprising a channel through which the gas cartridge and the bellows communicate with each other, an actuator configured to operate to open and close the channel, and a drive part configured to drive the actuator to open the channel in response to the detection of the collision of the vehicle.
