Vehicle Belt Assembly With Loop-Free Mounting Ends
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing belt assemblies for vehicles suffer from low accuracy in length control, require large spaces, and have exposed sewing threads that negatively impact appearance and pattern integrity.
Innovation Solution
A belt assembly with loop-free ends, where attachments form steps with the belt body, allowing for precise mounting and improved aesthetics, and utilizing overmolded parts and fasteners for secure connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the belt body is folded back and sewn by sewing thread to form a loop, then the belt assembly can be assembled, but the appearance is negatively affected by exposed sewing threads and manufacturing precision is low
Solution Approach 1:
The patent removes the sewing thread connection method entirely and extracts the belt end formation to use a loop-free design with attachment pieces instead. This eliminates the harmful exposed sewing threads and achieves precise length control through the attachment piece positioning rather than through sewing loop formation.
Solution Approach 2:
The patent changes the fundamental parameter of belt end configuration from loop-formed to loop-free, and changes the connection method from sewing to mechanical attachment. This parameter change enables precise length control and improved appearance while maintaining assembly functionality.
2Shape
If the belt body is folded back and sewn to form a loop, then the belt assembly can be assembled, but exposed sewing threads negatively impact appearance
Solution Approach 1:
The patent extracts and removes the sewing thread element entirely from the belt assembly design. By eliminating the sewing process and using loop-free ends with attachment pieces, the harmful exposed threads are removed while achieving precise length control through the attachment piece positioning system.
3Volume of moving object
If the belt assembly uses traditional loop formation with sewing threads, then assembly is possible, but the belt assembly requires large space
Solution Approach 1:
The patent removes the redundant loop formation structure and sewing threads, extracting only the essential belt body with loop-free ends. This space-efficient design maintains mounting reliability through the attachment piece and receiving groove interface, eliminating unnecessary volumetric requirements.
4Manufacturing precision
If the belt assembly uses loop-free ends with attachments, then appearance is improved and length control accuracy is improved, but new mounting structure is required
Solution Approach 1:
The patent merges the attachment piece with the belt body end to form an integrated mounting structure. The attachment piece is fixedly connected to the loop-free belt end, combining the belt function with the mounting function in a single integrated component that achieves precise length control without requiring separate sewing or additional fastening elements.

AI summary
The present application relates to a belt assembly for a vehicle and an arrangement for a vehicle including the belt assembly. The belt assembly (2) comprises a belt body (20) having at least two ends, at least one of which is loop-free, wherein the belt body (20) is fixedly provided with a first attachment (21) at the at least one end, wherein the first attachment forms a step with respect to at least one side surface of the belt body at the respective end of the belt body, wherein the first attachment (21), together with the belt body (20), form a first mounting end (22) of the belt assembly. The belt assembly may have improved appearance and improved accuracy.
