Rotating Airbag Mounting Board for Autonomous Driving Postures
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Airbag apparatuses in vehicles are ineffective in restraining riders when they are in autonomous driving mode, as the airbag cushions are designed for forward-facing postures, leading to increased injury risk due to the gap between the airbag and the rider.
Innovation Solution
An airbag apparatus with a mounting board installed on the vehicle's inner side surface, which can rotate and expand an airbag cushion towards the rider from the center and inner side, compensating for the gap and providing protection by inflating and expanding between the frontal airbag and the rider, and preventing secondary accidents from objects on the mounting board.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the airbag cushion is designed for forward-facing rider posture, then the airbag structure is simple and cost-effective, but the airbag cannot effectively restrain the rider when the rider is in autonomous driving mode with increased gap distance
Solution Approach 1:
The airbag cushion is divided into multiple independent airbag modules that can be selectively deployed. Instead of using a single large airbag system designed for forward-facing posture, the patent segments the protection system into multiple smaller airbag units positioned at different locations (center, inner side, outer side of the mounting board), allowing targeted deployment based on rider posture and collision type, thus improving protection effectiveness without requiring complete system redesign
Solution Approach 2:
The airbag system transitions from a static, fixed-position design to a dynamic, adjustable configuration. The mounting board can rotate between horizontal and vertical positions, and airbag modules can be selectively deployed based on detected rider posture. This dynamic adaptability allows the same airbag system to effectively protect riders in both forward-facing and autonomous driving postures
2Adaptability or versatility
If the mounting board is made rotatable to adjust airbag orientation, then the airbag can adapt to different rider postures, but the device complexity and control difficulty increase
Solution Approach 1:
The mounting board is designed with multi-functionality, serving both as a structural support for the airbag modules and as a rotatable positioning mechanism. By integrating the rotation function into the existing mounting board structure rather than adding separate adjustment mechanisms, the patent achieves adaptability to different rider postures while minimizing additional complexity
Solution Approach 2:
The system performs preliminary detection of rider posture before collision occurs, allowing the mounting board to be pre-positioned in the optimal orientation. This preliminary action ensures that when deployment occurs, the airbag is already oriented correctly for the detected posture, eliminating the need for complex real-time adjustment mechanisms during the collision event

AI summary
The present invention relates to an airbag apparatus for a vehicle. In order to attain the purpose, the airbag apparatus for a vehicle according to the present invention comprises: a mounting board positioned in front of a rider; and an airbag module which is installed on the mounting board and, when a vehicle collides, restrains and protects the rider by means of inflating and expanding an airbag cushion toward the rider. Therefore, when the vehicle collides, the airbag cushion is inflated and expanded from the mounting board and thus the rider can safely be protected.
