Automotive Seat Cover Fixing via Clamped Wire Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing seat devices for automobiles that incorporate a mounting unit to secure child seats increase component costs, necessitating a solution to reduce costs while maintaining functionality.
Innovation Solution
The seat device employs wires fixed to the seat frame or car body with covering portions that have a fixing portion clamped between the seat and the wire, eliminating the need for a separate mounting unit and reducing material usage by using separately formed covering portions made of skin material with a thicker fixing portion and constricted neck portion for secure fixation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a mounting unit (hook and loop fastener) is used to secure the cover body to the seat cushion or seat backrest, then the cover body can be firmly fixed, but the component costs increase
Solution Approach 1:
The patent combines the covering function and the fixing function into a single integrated structure. The cover body itself is formed with a fixing portion that directly engages with the seat cushion or seat backrest through a clamping mechanism, eliminating the need for a separate mounting unit. This merging of functions reduces component costs while maintaining fixation reliability.
Solution Approach 2:
The patent extracts the mounting unit from the system and replaces it with a simplified fixing portion integrated into the cover body. By removing the unnecessary mounting unit and retaining only the essential fixing functionality, the patent reduces component complexity and cost while preserving the necessary fixation capability.
2Shape
If an integral covering portion is used to cover multiple opening portions, then the aesthetic appearance is improved, but the material usage and cost increase
Solution Approach 1:
The patent divides the covering structure into multiple separate covering portions, each corresponding to a specific opening portion. This segmentation allows each cover to be optimally sized and shaped for its specific function, reducing overall material usage compared to a single large integral cover, while still providing complete aesthetic coverage of all openings.

AI summary
The seat device includes: wires (31), fixed at a car body frame, and adapted to fix a child seat; opening portions (33), disposed at a right seat (13A), and adapted to enable the child seat to be connected to the wires (31); and covering portions (35), a base end of each being mounted at the right seat (13A), a front end being a free end, and the covering portions (35) covering the opening portions (33). Each of the covering portions (35) includes a fixing portion (36). The fixing portion (36) is disposed at a front end of the covering portion (35), and is clamped between the right seat (13A) and a wire (31) so as to be fixed.
