Pivotable Vehicle Covering Device for Gap-Free Seat Adaptation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle covering devices face challenges in dynamically adapting to changing seat arrangements, leading to gaps between the covering device and the seat backrest, which affect their acoustically dampening and insulating functions, and can result in jamming or unsightly gaps.
Innovation Solution
A covering device with two articulated molded storage parts, where the second molded storage part is inclined due to a restoring device with a wedge-shaped sliding surface and a spring element, allowing it to pivot and align optimally with the seat backrest, ensuring a gap-free coverage and easy handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the covering device is designed to be stationary relative to the vehicle, then the structure is simple and stable, but gaps form when the seat arrangement is displaced
Solution Approach 1:
The front molded storage part is made dynamically adjustable through a pivotable connection with the rear molded storage part. This allows the front part to rotate and change its position dynamically, enabling the covering device to adapt to different seat arrangements while maintaining a relatively simple overall structure.
2Adaptability or versatility
If the front molded storage part is coupled to the seat arrangement, then gap-free coverage is achieved, but handling and adjustment of the seat becomes difficult
Solution Approach 1:
The coupling between the covering device and the seat arrangement is extracted or separated. Instead of directly coupling the front molded storage part to the seat, it is connected to the rear molded storage part, which remains stationary relative to the vehicle. This allows the seat to be handled independently without being constrained by the covering device.
3Reliability
If the spring element is fixed at both ends to the molded storage parts, then the restoring force is stable, but the articulation area lacks sufficient adjustment range
Solution Approach 1:
A guiding element is introduced as an intermediary component between the spring element and the molded storage parts. This guiding element allows the spring element to maintain its fixed connections while enabling relative movement and adjustment in the articulation area, thus providing both stable restoring force and sufficient adjustment range.
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 ensures a gap-free coverage, enhances acoustic insulation, and simplifies handling by eliminating the need for coupling with the seat arrangement, while maintaining dynamic adjustment to seat changes.
Implementation Method 1
at least one restoring device which spans the articulation area comprising the pivot axis and has an elastic spring element, which is attached to the first and the second molded storage part and which, in the installation position of first and second molded storage part in the motor vehicle when a pivoting force exerted by the rear seat backrest allows the second molded storage part to be pivoted out of its basic position against the restoring force exerted by the elastic spring element into a folded position
Implementation Method 2
the emanating from the spring element biased restoring force when the pivoting force exerted by the rear seat backrest decreases or ceases, moves the second molded storage part back into its basic position
