Quick-Release Vehicle Seat Supporting Device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional supporting devices for vehicle seats are not convenient to install and require passing through headrest clips or posts, limiting their ease of use and flexibility.
Innovation Solution
A quick-release supporting device with a limiting member, carrier, and engaging structures that allow the positioning forks to detachably insert into gaps between the headrest clips and seat back, enabling tool-free installation and release without detaching the headrest, and increasing the force applied to the headrest clips.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional supporting device is installed through headrest clips or posts, then the supporting device can be firmly fixed onto the seat back, but the installation process becomes inconvenient and time-consuming
Solution Approach 1:
The supporting device is divided into separate components: a limiting member with engaging structures that can independently engage with the seat back, and a headrest assembly that can be attached or detached separately. This segmentation allows the supporting device to be installed without requiring the headrest, improving installation convenience while maintaining firm fixation through the engaging structures
Solution Approach 2:
The engaging structures are pre-configured on the limiting member to engage with the seat back before the headrest is installed. This preliminary action ensures that the supporting device is firmly fixed in advance, making the subsequent headrest installation simpler and faster, thereby improving overall installation convenience
2Reliability
If the supporting device requires passing through headrest clips for installation, then the headrest must remain attached during installation, but this limits flexibility and prevents the headrest from being detached at any time
Solution Approach 1:
The system is segmented into a supporting device portion (limiting member with engaging structures) and a headrest portion that can be independently attached or detached. The engaging structures provide secure attachment to the seat back without requiring the headrest, enabling the headrest to be freely detached or attached as needed, thus improving flexibility while maintaining secure attachment
Solution Approach 2:
The limiting member acts as an intermediary between the seat back and the headrest. It provides a secure attachment point to the seat back through engaging structures, while serving as a mounting platform for the headrest. This intermediary allows the headrest to be detached at any time while maintaining the secure attachment of the supporting device to the seat back
3Ease of operation
If conventional supporting devices are installed through headrest components, then the installation process becomes complex, but a simplified tool-free installation mechanism is needed
Solution Approach 1:
The engaging structures are designed to automatically engage with the seat back through simple insertion and locking motions that do not require external tools. The limiting member self-secures to the seat back via the engaging structures, and the headrest can be similarly attached or detached without tools, achieving tool-free installation while keeping the mechanism relatively simple
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
Enables quick and convenient installation or release of the supporting device without tools, allowing the headrest to be detached at any time, and provides a secure attachment mechanism that does not require the headrest during installation.
Implementation Method 1
The threaded portion at least partially protrudes from the corresponding rail hole. The knob and the positioning fork are respectively arranged at two opposite sides of the limiting member, and wherein the knob is screwed to the threaded portion, so that the engaging member is movable relative to the limiting member along a height direction of the engaging structure for reducing a distance between the positioning fork and the limiting member.

AI summary
A vehicle seat and a quick-release supporting device thereof are provided. The quick-release supporting device includes a limiting member, a carrier, and two engaging structures. The carrier is fastened to the limiting member for carrying an object. The two engaging structures are respectively fastened to two rail holes of the limiting member. Each engaging structure includes an engaging member and a knob. The engaging member has a threaded portion and a positioning fork respectively arranged on two opposite portions thereof, and the threaded portion at least partially protrudes from the corresponding rail hole. The knob is screwed to the threaded portion, so that the engaging member is movable relative to the limiting member for reducing a distance there-between. The two positioning forks can be detachably inserted into two gaps between two headrest clips and a seat back, respectively.
