Abstract
The present disclosure relates to a safety airbag device, a vehicle seat and a vehicle. The safety airbag device includes a head airbag portion, a chest airbag portion, an airbag tensioning belt and an airbag tensioner. The head airbag portion covers at least side areas of a head of an occupant after deployment, and the head airbag portion has an asymmetric structure about a central axis of the seat, such that a first side of the head airbag portion extends at a length shorter than that extended by a second side of the head airbag portion, whereby a space for accommodating a second safety airbag device is reserved at the first side of the head airbag portion. One end of the chest airbag portion is connected to the first side or the second side of the head airbag portion, and the other end of the chest airbag portion is connected with the airbag tensioner via the airbag tensioning belt; during deployment, the chest airbag portion is configured to bring the airbag tensioning belt to pass over the head of the occupant and reach a position in front of the chest of the occupant, and the airbag tensioner is configured to pull the chest airbag portion to the position in front of the chest of the occupant by tensioning the airbag tensioning belt.
