Integrated Belt Guide and Net Partition Holder for Vehicle Rear Seats
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing safety devices for rear seat arrangements in vehicles, particularly in station wagons, incur high manufacturing and component costs due to separate reinforcement profiles for belt guide parts and net partition holders, increasing production time and structural weight.
Innovation Solution
Combining the belt guide part and net partition holder into a common structural unit that can be mounted on the vehicle body shell via a screw connection, eliminating the need for separate shell connections and reducing assembly time, while providing a dual function for belt deflection and net partition mounting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate reinforcement profiles are used for belt guide part and net partition holder, then the protective function and restraint function are reliably fulfilled under extreme loads, but manufacturing costs and component costs increase
Solution Approach 1:
The patent combines the belt guide part and net partition holder into a single integrated component that is mounted on the vehicle body shell via a single reinforcement profile. This merging eliminates the need for separate reinforcement profiles, reducing component costs and manufacturing complexity while maintaining the required protective and restraint functions through the unified structural design
Solution Approach 2:
The integrated component serves multiple functions simultaneously: it guides the safety belt, holds the net partition cassette, and provides structural reinforcement. This multi-functionality allows a single component to replace what would traditionally require separate components, thereby reducing overall system complexity and cost
2Reliability
If separate reinforcement profiles are used for belt guide part and net partition holder, then the protective function and restraint function are reliably fulfilled under extreme loads, but production time increases
Solution Approach 1:
By merging the belt guide part and net partition holder into a single integrated component mounted on one reinforcement profile, the assembly process is simplified. Fewer components mean fewer mounting operations and less assembly time, directly improving productivity without compromising the reliability of the safety system
3Reliability
If separate reinforcement profiles are used for belt guide part and net partition holder, then the protective function and restraint function are reliably fulfilled under extreme loads, but structural weight increases
Solution Approach 1:
The integration of the belt guide part and net partition holder into a single component mounted on one reinforcement profile eliminates redundant structural elements. This reduces the total amount of material required while maintaining the necessary strength and stiffness to handle extreme loads, thereby reducing structural weight

AI summary
The device has a belt guide part deflecting a safety belt (7) to a belt winder (11). The belt guide part is mounted together with the belt retractor in a region of a rear-side hold to a vehicle shell. The belt guide part and a holder (25) for a wetting running wall cassette (23) are mounted together to form a common structural unit, which is mounted on a common connection of the vehicle body shell. The belt guide part is mounted on a reinforcing profile of the vehicle body shell by interposition of the holder that is supported by a fuse element in a base body of the guide part.
