Vehicle Seat Cover Tab Fixation Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle seat protective covers face challenges in secure fixation, ease of handling, and unimpeded access for robotic handling devices, often requiring complex assembly and being prone to slipping or detachment.
Innovation Solution
A protective cover for vehicle seats featuring a front and back layer connected via folds or welds, with upper and lower pockets and a tab design that prevents the cover from being pulled off, utilizing a closed-edge recess to create a tab that secures the cover to the seat's projections, ensuring easy application and secure fixation without additional assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the protective cover is secured using additional components like rubber bands or foil strips, then the fixation reliability is improved, but the device complexity and ease of operation deteriorate
Solution Approach 1:
The patent integrates the fixation function directly into the protective cover structure by forming a tab from the back layer material itself. The tab is created by separating a portion of the back layer to form a closed-edge recess, eliminating the need for separate rubber bands or foil strips. This merging of the securing element into the cover structure reduces device complexity while maintaining fixation reliability.
Solution Approach 2:
The protective cover is designed to be self-securing through its own structural features. The tab with the closed-edge recess allows the cover to anchor itself to the seat without requiring external fastening components or additional assembly steps. The cover serves its own fixation needs through the integrated tab design, improving ease of operation while maintaining reliable attachment.
2Ease of operation
If the protective cover uses a simple design without additional securing elements, then the ease of operation is improved, but the fixation reliability deteriorates
Solution Approach 1:
The fixation function is merged into the protective cover structure through the tab formed from the back layer. This integrated design maintains simplicity for easy installation while providing reliable fixation through the tab's anchoring action on the seat projection, eliminating the need for complex additional securing elements.
Solution Approach 2:
The tab extends in a direction perpendicular to the main body of the protective cover, utilizing the third dimension to achieve fixation. The tab projects backward from the seat cushion and anchors onto a projection on the backrest, creating a secure connection that maintains simplicity while ensuring reliable attachment during vehicle operation.
3Reliability
If the protective cover is tightly secured to prevent slipping, then the fixation reliability is improved, but the ease of removal and reapplication deteriorates
Solution Approach 1:
The protective cover is segmented into functional zones: the main body that covers the seat cushion and backrest, and the tab that provides secure anchoring. This segmentation allows the cover to be tightly secured during normal use while enabling easy removal by simply pulling on the tab, which concentrates the removal force on the anchored portion without requiring forceful manipulation of the entire cover.
4Reliability
If the protective cover design requires additional securing components, then the fixation reliability is improved, but the manufacturing precision requirements worsen
Solution Approach 1:
The tab is formed as an integral part of the protective cover from the same back layer material, eliminating the need for separate securing components. This merging reduces manufacturing precision requirements as it involves a single forming operation rather than multiple assembly steps requiring precise alignment of different components. The closed-edge recess is created by separating a portion of the back layer, which can be done through standard cutting or punching operations.
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
The solution provides a secure, easy-to-handle vehicle seat protective cover that remains firmly in place, allowing unimpeded robotic access and easy installation, while minimizing production effort and ensuring the cover's secure attachment to the seat.
Implementation Method 1
The front layer and the back layer are connected to one another in the region of their edges via folds or welds
Implementation Method 2
an elastic band can be used as a separate part for the vehicle seat protective film, which, after the vehicle seat protective film has been pulled over it, is guided as a closed loop over the backrest

AI summary
The invention relates to a vehicle seat cover (5). According to the invention, the vehicle seat cover (5) forms at least one flap (16) in its lateral side area. If the vehicle seat cover (5) is fitted onto a vehicle seat (1) with an upper pocket (11) and/or a lower pocket (10), the vehicle seat cover (5) can be additionally secured to the vehicle seat (1) by the flap (16) wrapping around a projection (18), for example, a rotary knob (17) for adjusting the inclination of a backrest (4).
