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 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.
A control method of an occupant restraining apparatus, the occupant restraining apparatus comprising a support configured to support an airbag deployed by pivoting, a bellows configured to pivot the support while being stretched by gas, a gas cartridge configured to store the gas for expanding the bellows, and an electric gas valve connecting the bellows and the gas cartridge and configured to control supply of the gas from the gas cartridge to the bellows, the control method comprising:
- starting an operation of a collision sensor to detect a collision of a vehicle;
- determining whether or not the collision sensor has detected the collision of the vehicle;
- starting operations of the airbag and the electric gas valve in response to determining that the collision sensor has detected the collision;
- and
- after starting operations of the airbag and electric gas valve, simultaneously operating an inflator of the airbag and operating the electric gas valve to supply the gas from the gas cartridge to the bellows to stretch the bellows so that the support is pivoted to support the airbag.
