Vehicle Seat Slide Apparatus Automatic Stopper Release Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle seat slide apparatuses face operational inefficiencies, particularly in positional adjustments, as they require complex release operations to unlock the upper rail's movement, which can lead to deteriorated usability when switching between seating and non-seating areas or between rows in a vehicle.
Innovation Solution
A vehicle seat slide apparatus featuring a lower rail, an upper rail, a lock mechanism, a stopper mechanism, and a guide portion, where the stopper mechanism engages at a predetermined position to lock the upper rail's movement and allows easy release through an operation force or guided movement, enhancing operational simplicity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the stopper mechanism is designed to require manual release operation, then the upper rail can be securely locked at the predetermined position, but the operational complexity increases and ease of operation deteriorates
Solution Approach 1:
The stopper member is designed to automatically release from the stopper portion when the upper rail moves in the opposite direction. The guide portion on the stopper member interacts with the stopper portion to guide automatic disengagement, eliminating the need for manual release operations while maintaining secure locking when needed.
2Ease of operation
If the stopper mechanism is designed with automatic release through guide portion, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The guide portion is integrated directly onto the stopper member itself, combining the locking and releasing functions into a single component. This merging approach achieves automatic release functionality without adding separate complex mechanisms, thereby minimizing device complexity while improving ease of operation.
3Ease of operation
If the upper rail allows free movement for area recognition, then the ease of operation is improved, but the loss of time due to repeated manual locking increases
Solution Approach 1:
The stopper mechanism is pre-configured with the guide portion that automatically engages and disengages based on the direction of movement. This preliminary design eliminates the need for repeated manual locking operations when moving between areas, saving time while maintaining ease of movement.

AI summary
Provided is a slide door device for a vehicle seat slide apparatus including: a lower rail configured to be fixed to a vehicle floor; an upper rail configured to be fixed to a seat; a lock mechanism that selectively locks a movement of the upper rail at an arbitrary position of the upper rail with respect to the lower rail; a stopper mechanism that has a stopper portion provided in the lower rail and a stopper member movably provided in the upper rail; an operation member that allows the movement of the upper rail, which is locked at the predetermined position, in the one direction by inputting an operation force for releasing to the stopper member; and a guide portion that is formed on the stopper member, and guides the stopper member so as to release the engagement between the stopper member and the stopper portion.
