Description
technical field [0001] The invention belongs to the field of occupant protection in motor vehicle safety devices, and in particular relates to a motor vehicle dual airbag safety device and a control method thereof for protecting the safety of rear occupants when the motor vehicle undergoes emergency braking or frontal collision. Background technique [0002] When emergency braking or frontal collision occurs in the motor vehicle, the rear occupants will rush forward under the action of inertial force. During this process, the heads of the rear occupants will hit the headrests and the upper part of the backrests of the front seats, causing the rear occupants to suffer varying degrees of injuries to their heads, necks, chests and other parts. In order to reduce the injury of the rear passengers, airbags are usually installed in the front seats, but due to the narrow space in the rear row, the instantaneous detonation of the traditional airbags will cause serious injury to the ...
