Regulating Member for Piping Leg Orientation in Vehicle Seat Covers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing interior equipment designs, such as vehicle seats, face issues with the stability and reproducibility of the cover edge formed by piping, where the leg portion of the piping falls due to locking force alone, leading to potential meandering or breaking of seams and instability in the cover configuration.
Innovation Solution
Incorporating a regulating member attached to the second cover side of the sewn portion, which protrudes from the end and falls toward the first cover side with the leg portion of the piping, utilizing elastic repulsive force from the corner portion to maintain the falling direction of the leg portion and ensure the cover is raised by the piping along the edge of the pad member.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the leg portion of the piping is held only by the locking force of the locking portion, then the structure is simple, but the configuration is unstable and the falling direction cannot be kept constant
Solution Approach 1:
A regulating member is introduced as an intermediary component between the piping leg portion and the corner portion. This regulating member mediates the interaction by providing a regulated falling path through the corner portion, ensuring the leg portion falls in a constant direction while maintaining structural simplicity. The corner portion acts as a guide that directs the falling motion without requiring complex fixation mechanisms.
2Shape
If the piping is arranged to form an edged appearance along the periphery, then the design quality is improved, but the seam allowances may meander or break due to instability
Solution Approach 1:
The corner portion is designed to preemptively guide the falling direction of the piping leg portion before the seam allowances are sewn. By establishing a regulated falling path in advance, the system prevents potential meandering or breaking of seams during the sewing process. This preliminary guidance ensures that the edged appearance is formed correctly without compromising seam integrity.
3Reliability
If the portion of the cover raised by the piping is arranged below the corner portion, then the piping is secured, but the configuration lacks shape reproducibility and is displaced from the periphery
Solution Approach 1:
The corner portion provides a geometric constraint that gives feedback to the piping leg portion during the falling process. As the leg portion falls, the corner portion's geometry ensures it follows a predetermined path that reproduces the desired shape consistently. This geometric feedback mechanism ensures both secure positioning and shape reproducibility without displacement from the periphery.

AI summary
An interior equipment including: a sewn portion where seam allowances of first and second covers are overlapped in a state where front surface thereof face each other; a regulating member which regulates a falling direction of a leg portion of a piping, wherein the regulating member is attached to a second cover side of the sewn portion and protrudes from an end of the sewn portion, and wherein, in a state of being pressed against a corner portion of a pad member, the regulating member falls toward the first cover together with the leg portion of the piping which is co-sewn to the sewn portion, and thereby a portion of the first cover which is folded back at a seam is arranged to be overlapped with the sewn portion on the corner portion in a state of being raised by a head portion of the piping.
