Airbag Module Magnetic Attachment for Vehicle Body
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing airbag module attachment methods require additional manufacturing steps and increased costs due to the need for pre-drilled holes in the vehicle body, limiting flexibility in attachment locations and increasing assembly effort.
Innovation Solution
The airbag module incorporates a holder with a fixing point and magnetic fastening elements, such as self-adhesive magnetic tapes, to securely attach the gas bag module to the vehicle body without screws or clamps, ensuring proper inflation and deployment direction, and allowing flexible attachment locations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If screws or spring clamps are used to attach the gas bag module, then the attachment is secure, but pre-drilled holes are required which increase manufacturing steps and costs
Solution Approach 1:
The patent replaces the mechanical fastening system (screws, clamps requiring pre-drilled holes) with a magnetic fastening system. The magnetic fastening elements attach the gas bag module to the vehicle body through magnetic attraction without requiring any holes or mechanical penetration, thereby eliminating the harmful manufacturing steps while maintaining secure attachment.
2Ease of manufacture
If pre-drilled holes are made in predefined locations, then the attachment structure is defined, but flexibility in attaching the gas bag module is severely limited
Solution Approach 1:
The patent introduces dynamic flexibility to the attachment system by using magnetic fastening elements that can be positioned at various locations on the vehicle body without requiring predefined holes. The magnetic attachment points can be adjusted and repositioned, allowing the gas bag module to be attached at optimal locations based on vehicle design variations or installation requirements, thereby significantly improving adaptability.
3Ease of operation
If magnetic fastening elements are used to reduce installation effort, then flexibility is improved, but the gas bag inflation reliability must be ensured
Solution Approach 1:
The patent segments the attachment system into two distinct functional components: magnetic fastening elements for simplified installation and positioning, and a separate fixing point mechanism (pin through opening) for securing the gas bag to the holder. This segmentation allows the magnetic elements to provide ease of installation while the dedicated fixing point ensures inflation reliability, resolving the contradiction between operational ease and system reliability.

AI summary
The invention relates to an airbag model (10) for a motor vehicle and to a motor vehicle body. The object of the invention is to secure an airbag module (10) to the motor vehicle in a simple and cost-effective manner. This is achieved in that an airbag module (10) comprises a gas generator (12), a support (14) for the gas generator (12) and a folded airbag (16) which is inflated by the gas generator (12) in the event of activation such that the airbag (16) unfolds. The airbag module (10) comprises at least one magnetic securing element (24, 26) via which the airbag module (10) can be secured to the motor vehicle body.
