Synchronous Sliding Device for Vehicle Seats
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sliding devices for vehicle seats face difficulties in synchronizing release levers when they are positioned differently along the sliding direction or have varying specifications, making it challenging to operate them in a synchronized manner.
Innovation Solution
The sliding device incorporates a movable rail with a lock mechanism and release lever system, where the operating lever and operation portion can be adjusted to synchronize the release levers, allowing for easy synchronization by modifying the specifications such as shape, distance, and displacement, and incorporating a design where the operating lever contacts the operation portion within a specific range to minimize torsion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the first release lever and the second release lever are located at different positions or have different specifications, then the sliding device can accommodate various vehicle seat configurations, but it becomes difficult to synchronize the operation of the two release levers
Solution Approach 1:
The patent applies parameter changes by making the operating lever displaceable between different positions (first position for contacting first release lever, second position for contacting second release lever). This allows the same operating lever to adapt to different release lever positions and specifications while maintaining synchronized operation through a single handle
Solution Approach 2:
The operating lever is designed to be dynamically adjustable between different operational positions. The lever can be displaced to contact either the first or second release lever depending on the configuration, enabling the system to adapt to different vehicle seat arrangements while maintaining ease of operation
2Ease of operation
If the operating lever is designed to contact the operation portion, then the release lever can be operated, but dimensional variations may cause misalignment and affect synchronization
Solution Approach 1:
The patent employs parameter changes by making the operating lever displaceable between different positions. This displacement capability compensates for dimensional variations and misalignments, ensuring reliable contact with the operation portion regardless of manufacturing tolerances while maintaining synchronization
Solution Approach 2:
The operating lever automatically adjusts its position to achieve proper contact with the operation portion. The lever's displacement capability allows it to self-align and compensate for dimensional variations without requiring external adjustment mechanisms

AI summary
Provided is a sliding device that allows two release levers to operate in a synchronous manner. The sliding device includes a lock portion that is displaceable between a locking position and a non-locking position; a release lever configured to be displaced by an operating force; an operation portion provided at a first end of the release lever in an extending direction thereof to receive the operating force; an action portion provided at a second end of the release lever in the extending direction thereof to transmit the operating force to the lock portion via the release lever; and an operating lever provided to the movable rail and displaceable between an operating position to apply the operating force to the operation portion and a non-operating position to apply no operating force to the operation portion.
