Vehicle Seat Bracket With Interference-Avoiding Coupling Member
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle seat designs require an increase in height or additional components when installing a load detection sensor, as the sensor's thickness shifts the mounting holes' positions, leading to inefficiencies in seat height maintenance and component management.
Innovation Solution
A vehicle seat design featuring a bracket with an upright wall and a coupling member, where the fastening member is positioned to overlap the main body, allowing the same coupling member to be used with and without the sensor, and incorporating an interference-avoiding portion to prevent protrusions from interfering, thus maintaining seat height without adding components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a load detection sensor is installed between the bracket and the slide rail, then load detection function is improved, but the mounting hole positions are shifted upward causing seat height increase
Solution Approach 1:
The patent changes the mounting approach from vertical stacking (which increases height) to horizontal integration (which maintains height). The coupling member is designed with a receiving portion that horizontally integrates the load detection sensor, rather than vertically stacking it between the bracket and slide rail. This dimensional change allows the sensor to be mounted without increasing seat height.
Solution Approach 2:
The load detection sensor is nested within the receiving portion of the coupling member. The coupling member's receiving portion is specifically designed to accommodate the sensor, with fastening members that secure the sensor within this receiving portion. This nesting approach allows the sensor to be integrated into the existing structure without adding external height.
2Reliability
If the mounting hole positions are shifted upward due to sensor thickness, then load detection function is maintained, but additional components or height adjustment is required
Solution Approach 1:
The coupling member is designed with multi-functionality: it provides structural support for the seat, serves as a mounting platform for the load detection sensor through its receiving portion, and maintains the original mounting hole positions. This universal design allows the same coupling member to fulfill multiple functions without requiring additional components or height adjustments.
Solution Approach 2:
The coupling member acts as an intermediary between the bracket and the slide rail, with its receiving portion serving as an intermediate platform for mounting the load detection sensor. This intermediary structure allows the sensor to be integrated without disrupting the original mounting geometry or requiring additional components.

If the fastening member is positioned to overlap the main body, then seat height is maintained, but interference with the protruding portion may occur
Solution Approach 1:
The coupling member is segmented into distinct functional portions: a main body that maintains seat height, a receiving portion that accommodates the sensor, and fastening members that secure components. This segmentation allows each portion to be optimized for its specific function while minimizing interference between components.
Solution Approach 2:
The coupling member features asymmetric design in its receiving portion and fastening member arrangement. The receiving portion is specifically shaped to accommodate the sensor, and the fastening members are positioned asymmetrically to secure the sensor while avoiding interference with the protruding portion of the bracket. This asymmetric design allows the fastening member to overlap the main body in the height direction without causing interference.

AI summary
A vehicle seat includes: a bracket; and a seat frame that is mounted on the bracket through coupling member. The bracket has main body, and upright wall extending upward from the main body and coupled to the main body. The coupling member is mounted at one end on the upright wall with fastening member. The main body is provided with interference avoiding portion that prevents interference with protruding portion of the fastening member protruding from the upright wall toward the main body.
