Integrated Seat Lock Release for Simultaneous Slide Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing seat locking systems in vehicles require inconvenient sequential operation to release the left-right slide and forward-backward slide locking devices, making it difficult to adjust the seat position efficiently.
Innovation Solution
A seat locking release device that simultaneously releases the left-right slide and forward-backward slide locking devices using integrated cables and a pulley system, with a stroke adjusting mechanism to customize the release force.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If independent locking devices are used for left-right slide and forward-backward slide, then each locking device can be reliably fixed, but the operation complexity increases and user convenience deteriorates due to sequential release requirement
Solution Approach 1:
The patent combines two independent locking release operations into a single integrated release mechanism. The release lever is connected to both the left-right slide locking device and the forward-backward slide locking device through a common cable system, allowing simultaneous release of both locks by a single lever operation, thus improving ease of operation while maintaining reliable locking through the independent cable pathways
2Adaptability or versatility
If separate cable systems are used for left-right locking and forward-backward locking, then each locking mechanism can be independently controlled, but the device complexity increases
Solution Approach 1:
The patent implements a universal cable management system where a single cable assembly serves multiple functions: it controls both the left-right slide locking and the forward-backward slide locking through different connection points. The cable system is designed with universal mounting brackets and adjustable connection points that allow one cable structure to perform the work of what would traditionally require two separate cable systems, thereby reducing device complexity while maintaining independent control capability
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Improves user convenience by allowing simultaneous release of both locking devices, enabling easy adjustment of the seat position and reducing the effort required for cable stroke adjustments.
Implementation Method 1
a pulley to which the left-right slide cable and the forward-backward slide cable are connected, to rotate together with the lever
Implementation Method 2
the stroke adjusting device may be formed in a cam shape as a whole so as to be able to push out the left-right slide cable or the forward-backward slide cable
Implementation Method 3
the integrated locking release device may further include a planetary gear combination installed between the pulley and the lever to increase a releasing force of the pulley by decelerating a rotation of the lever

AI summary
Provided is a seat locking release device including a left-right slide cable that is connected to a left-right locking device for fixing or releasing a left-right movement of a seat to apply a releasing force to the left-right locking device, a forward-backward slide cable that is connected to a forward-backward locking device for fixing or releasing a forward-backward movement of the seat to apply a releasing force to the forward-backward locking device, and an integrated locking release device that simultaneously applies the releasing force to the left-right slide cable and the forward-backward slide cable.
