Seat Rail Memory Bracket for Ingress-Egress Stop Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle seat adjustment systems are prone to malfunction when excessive force is applied, leading to dislodgement of memory components and rendering the seat inoperable, causing customer dissatisfaction.
Innovation Solution
A vehicle seat design incorporating a rail assembly with a locking device, ingress-egress mechanism, and memory bracket that allows for smooth transition between use and non-use positions, utilizing a stop member system to prevent dislodgement and ensure reliable operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a known adjusting system is used without enhanced protection mechanisms, then the structure remains simple, but the system is prone to malfunction when excessive force is applied
Solution Approach 1:
The patent applies beforehand cushioning by providing a foam member positioned between the memory component and the movable rail. This foam member acts as a protective cushion that absorbs excessive force applied during seat adjustment, preventing damage to the memory component while maintaining overall system simplicity. The cushioning element is pre-installed in the force application path to protect vulnerable components.
2Reliability
If memory components are protected from excessive force, then component damage is prevented, but the device structure becomes more complex
Solution Approach 1:
The patent uses an intermediary approach by introducing a foam member as a mediator between the memory component and the external force applied through the rail assembly. This intermediary element protects the memory component from direct exposure to excessive force while maintaining a relatively simple overall structure. The foam member serves as a buffer that absorbs shock without requiring complex protective mechanisms.

AI summary
A memory bracket configured for use in a vehicle seat rail assembly. The rail assembly including a translatable rail provided with a first stop member and the memory bracket fixed to a fixed rail and including a second stop member. In response to the translatable rail being positioned in a use position, the first stop member contacts the second stop member, and as the translatable rail moves in the longitudinal direction from an ingress-egress position to the one or more use positions, a portion of the memory bracket engages and displaces a mechanical effector of an ingress-egress aid to permit the backrest to pivot away from the seating surface.
