Airbag Bracket Force Distribution via Integrated Fastening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing airbag installation devices fail to reliably absorb the forces generated during airbag deployment and do not adequately address stringent safety requirements for head impacts.
Innovation Solution
A U-shaped airbag bracket with integral fastening sections for the airbag device, instrument panel, and vehicle structure, featuring angled limbs, reinforcement structures, and strategically placed passage openings to distribute and absorb forces effectively during crashes, particularly in the Z direction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing airbag installation devices are used, then the structure is simple, but the forces during airbag triggering cannot be reliably absorbed
Solution Approach 1:
The patent combines multiple fastening functions into a single integrated airbag bracket structure. The bracket integrates the airbag fastening section, instrument panel fastening section, and supporting fastening section into one cohesive component that attaches to the vehicle's supporting structure, thereby improving force absorption capability while maintaining structural efficiency.
Solution Approach 2:
The airbag bracket is divided into distinct functional sections: an airbag fastening section for securing the airbag, an instrument panel fastening section for mounting the instrument panel, and a supporting fastening section for attachment to the vehicle structure. This segmentation allows each section to be optimized for its specific function while working together as a unified system.
2Reliability
If existing airbag installation devices are used, then the manufacturing process is simple, but safety requirements for head impacts are not adequately met
Solution Approach 1:
The patent integrates multiple safety functions into a single airbag bracket structure that provides both airbag deployment support and instrument panel mounting with head impact protection. This unified structure meets stringent safety requirements while streamlining the manufacturing process compared to using separate components.
3Strength
If the airbag bracket fastens multiple components, then the force distribution is improved, but the device complexity increases
Solution Approach 1:
The airbag bracket features distinct fastening sections for different components: an airbag fastening section with appropriate attachment points, an instrument panel fastening section for securing the instrument panel, and a supporting fastening section for vehicle structure attachment. This segmentation enables effective force distribution across multiple attachment points while maintaining a relatively simple overall structure.

AI summary
An airbag bracket has at least one airbag fastening section (31, 32, 41, 42) for fastening an airbag device to the airbag bracket (1) and has at least one instrument panel fastening section (11, 12, 13, 23, 24) for fastening an instrument panel to the airbag bracket. Thus, forces occurring during the triggering of the airbag device can be reliably absorbed. The airbag bracket (1) has at least one supporting fastening section (35, 45) for fastening the airbag bracket (1) to a supporting structure of a motor vehicle.
