Vehicle Seat Sliding Structure with Movable Pin
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle seat displacement in the anteroposterior direction requires cumbersome loosening and re-fastening of bolts, making the process labor-intensive and inefficient.
Innovation Solution
A sliding structure featuring seat positioning holes on the vehicle body and a movable positioning pin, combined with a seat slide support system that includes a long hole and guide portion, allowing the seat to be easily slid without detaching or re-attaching fastening bolts, and optionally incorporating multiple positioning pins for enhanced accuracy and flexibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the conventional bolt attachment structure is used to fix the vehicle seat to the chassis frame, then the seat can be securely fixed at four positions, but the displacement process requires cumbersome loosening and re-fastening of bolts making it labor-intensive and time-consuming
Solution Approach 1:
The patent applies the dynamics principle by making the positioning pin movable rather than fixed. The positioning pin can automatically move between a retracted state (when not engaged) and a projecting state (when engaged with positioning holes), enabling the seat to be easily displaced by simply moving the pin without requiring bolt loosening or re-fastening operations
Solution Approach 2:
The positioning pin structure enables self-service operation where the pin automatically engages with the positioning holes when the seat is moved to the desired position. The elastic member provides automatic resetting functionality, allowing the pin to return to its retracted state after engagement, eliminating the need for manual intervention to disengage fastening elements
2Adaptability or versatility
If multiple positioning holes are provided aligned in the anteroposterior direction for seat displacement, then the seat can be positioned at multiple locations, but the structure becomes more complex requiring additional positioning mechanisms
Solution Approach 1:
The patent applies segmentation by dividing the positioning function into two independent components: multiple positioning holes provided on the chassis frame and a single movable positioning pin on the seat. This segmentation allows the seat to be positioned at multiple locations (adaptability) while keeping the positioning mechanism simple (the pin simply moves to engage with different holes)
Solution Approach 2:
The positioning pin serves multiple functions: it acts as both a positioning element and a locking mechanism. By making the pin movable, it can engage with any of the multiple positioning holes aligned in the anteroposterior direction, providing universal positioning capability across multiple locations without requiring separate mechanisms for each position

AI summary
A sliding structure for a vehicle seat, the sliding structure configured to attach the vehicle seat slidably in an anteroposterior direction to a vehicle body. The sliding structure including: a seat positioning portion including positioning holes formed in the vehicle body and aligned in the anteroposterior direction, and a positioning pin attached to the seat and configured to be movable to a projecting position projected to one of positioning holes to be engageable therewith, and to a withdrawing position withdrawn from the positioning hole; and a seat slide support portion including a seat support portion formed with the vehicle body, a seat attachment portion disposed at the bottom of the seat and having a long hole extending in the anteroposterior direction, and a seat guide portion provided to the seat support portion and configured to be engaged with the long hole and guide the seat movably in the anteroposterior direction.
