Seat Belt Bracket Cross-Section Reinforcement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
General seat belt mounting brackets have insufficient structural connection with other vehicle members, leading to reduced structural efficiency and reinforcement, as they are primarily mounted on pillar internal members without additional connections, thus not significantly contributing to the overall vehicle body strength.
Innovation Solution
A seat belt mounting bracket structure that connects the pillar reinforcement outside the vehicle body with the pillar internal upper inside the vehicle body, forming a closed cross-section and using curved reinforcement surfaces to engage with the pillar reinforcement, thereby enhancing the connection strength between the pillar reinforcement, internal upper, and connecting members.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a general seat belt mounting bracket is mounted only on a pillar internal member, then the mounting function is simple and easy to manufacture, but the structural connection with other vehicle members is insufficient and the overall vehicle body strength is reduced
Solution Approach 1:
The patent merges the seat belt mounting bracket with additional connecting members that link to multiple vehicle components (pillar internal member, pillar external member, and seat frame). This combination transforms a single-function mounting bracket into a multi-functional structural element that both mounts the seat belt and reinforces the vehicle body framework, thereby improving vehicle body strength without proportionally increasing complexity
Solution Approach 2:
The mounting bracket is designed to perform multiple functions simultaneously: it serves as the mounting point for the seat belt anchor while also acting as a structural connector between the pillar internal member, pillar external member, and seat frame. This multi-functionality allows the bracket to contribute to both seat belt installation and overall vehicle body structural integrity
2Reliability
If a seat belt mounting bracket is designed as a single function part mounted on pillar internal member, then the device complexity is low, but the structural efficiency and reinforcement effect are insufficient
Solution Approach 1:
The patent combines multiple structural connections into a single integrated mounting bracket assembly. The bracket simultaneously connects to the pillar internal member, pillar external member, and seat frame, merging what would otherwise be separate reinforcement structures into one unified component that enhances structural efficiency
3Strength
If the seat belt mounting bracket uses an open structure simply connected to top and bottom inside pillar member, then the ease of manufacture is high, but the contribution to structure strength is minimal
Solution Approach 1:
The patent transforms the simple open structure into a more complex closed-loop structure by adding connections to the pillar external member and seat frame. This merging of multiple connection points creates a rigid triangular reinforcement pattern that significantly enhances pillar strength while maintaining reasonable manufacturability through standard welding and bolting processes

AI summary
A seat belt mounting bracket mounting structure includes a pillar portion, a connecting member connecting the pillar portion and another forward pillar portion positioned in front of the vehicle body of the pillar portion, and a seat belt mounting bracket mounted at a cross position of the pillar portion and the connecting member.
