Vehicle Seat Rail Locking for Adjustable Stable Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle seat attachment methods lack a technically and economically advantageous solution for secure and flexible mounting of interior equipment, such as seat assemblies, on vehicle floors, requiring improved attachment devices that ensure stability and ease of installation.
Innovation Solution
A device comprising a carriage connectable to a seat assembly and a floor rail with a locking assembly, featuring latching portions and recesses, allows the carriage to be securely fixed at different points along the rail, preventing movement and providing a compact, reliable locking mechanism for various interior equipment in vehicles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a locking assembly with latching portions and recesses is used to fix the carriage to the floor rail, then the reliability of the attachment is improved, but the device complexity increases
Solution Approach 1:
The locking assembly is segmented into multiple independent latching portions (at least two) that can engage with corresponding recesses at different positions along the floor rail. This segmentation allows the system to achieve reliable multi-point fixation while maintaining modular simplicity in each individual latching element.
Solution Approach 2:
The locking mechanism is designed to be self-latching, where the latching portions automatically engage with the recesses when the carriage is positioned on the floor rail. The design eliminates the need for additional actuating mechanisms or complex control systems, as the geometric configuration of the latching portions and recesses inherently provides the locking function.
2Adaptability or versatility
If the carriage is made movable in the longitudinal direction of the floor rail, then the adaptability of the seat assembly is improved, but the stability of the attachment deteriorates
Solution Approach 1:
The locking assembly transitions from a static fixed-position design to a dynamic multi-position system. The latching portions can engage with multiple recesses distributed along the longitudinal direction of the floor rail, allowing the carriage to be securely locked at various positions while maintaining stability at each selected position. This dynamic capability provides both adjustability and stability.
Solution Approach 2:
Different sections of the floor rail have recesses positioned at specific locations to provide optimal locking points. The latching portions are designed with specific geometric properties that enable them to engage with these locally positioned recesses, creating stable attachment at each selected position while allowing movement between positions.
3Reliability
If multiple latching portions are provided in the locking assembly, then the reliability of the locking is improved, but the manufacturing complexity increases
Solution Approach 1:
Multiple latching portions are combined into a single integrated locking assembly component rather than being separate parts. This merging approach maintains the reliability benefits of multi-point locking while simplifying manufacturing, as the entire locking assembly with all latching portions can be produced as one piece or pre-assembled unit that attaches to the carriage in a single operation.

AI summary
The invention relates to a device for attaching a seat assembly in a vehicle, wherein the device comprises a carriage and a floor rail, wherein the carriage can be fixed on the floor rail, wherein the floor rail has a longitudinal slot with a support section limiting the longitudinal slot, wherein a locking assembly having a locking element adjustably accommodated on the carriage is provided for fixing the carriage attached to the floor rail. According to the invention, the locking assembly comprises multiple recesses in at least one rail longitudinal wall of the floor rail, wherein the locking element has a latch section and a contact section in such a way that, with the fixing of the carriage, the latch section engages into a recess in the rail longitudinal wall and the contact section comes into contact with the inner side of the support section.
