Integrated Bracket for Vehicle Seat Lever and Detector
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle seat designs require a large number of components, including separate manipulation levers and seat position detectors, which increases complexity and reduces efficiency.
Innovation Solution
A vehicle seat design that integrates the manipulation lever and seat position detector within a single bracket, secured to the upper rail, reducing the number of components and enhancing rigidity through a slit design that separates the lever's support and detector mounting portions, allowing for reduced strain transmission and improved functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the manipulation lever and seat position detector are disposed separately inside the lower rail, then each component can be independently installed and maintained, but the number of components increases and the structure becomes more complex
Solution Approach 1:
The patent combines the manipulation lever and seat position detector into a single integrated assembly that is disposed together inside the lower rail. This merging reduces the number of separate components while maintaining the functional independence of each element through their integrated design, directly resolving the contradiction between component count and ease of manufacture.
2Device complexity
If the bracket is designed as an integrated structure supporting both the manipulation lever and seat position detector, then the number of components is reduced, but the rigidity and strain isolation may be compromised
Solution Approach 1:
The bracket is segmented into a first portion supporting the manipulation lever and a second portion supporting the seat position detector, separated by a slit. This segmentation allows the bracket to function as a single integrated component reducing overall complexity, while the slit provides strain isolation to maintain rigidity and prevent force transmission between the lever and detector portions.
3Device complexity
If the manipulation lever is disposed inside the upper rail, then the seat adjustment mechanism is simplified, but the space for other components becomes more constrained
Solution Approach 1:
The manipulation lever and seat position detector are nested together inside the lower rail as an integrated assembly. This nesting arrangement simplifies the seat adjustment mechanism by providing centralized access to both components while efficiently utilizing the limited space within the lower rail, avoiding the need for separate disposal locations.

AI summary
A vehicle seat includes a seat cushion, a seat back, a seat position adjusting device that moves and adjusts the seat cushion back and forth, and a seat position detector that detects a position of the seat cushion. The seat position adjusting device includes an upper rail that supports the seat cushion, a lower rail secured to a floor of a vehicle and configured to move the upper rail, a manipulation lever disposed inside with respect to the upper rail, and a bracket that is secured to the upper rail and supports the manipulation lever. The bracket includes a first portion that supports the manipulation lever, a second portion integratedly formed with the first portion and to which the seat position detector is mounted, and a slit that separates the first portion and the second portion.
