ISOFIX Guide Element Fastening for One-Step Seat Cushion Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing process of installing ISOFIX guide elements in vehicle seats is time-consuming as they are typically installed separately from the seat cushion and require additional steps, complicating the mounting sequence.
Innovation Solution
A guide element with a base section, rear side section, and side sections, featuring an insertion opening and bracket opening with notches, and a fastening element with an oblong-hole-type opening, allowing connection to a tab on the seat cushion before mounting, enabling simultaneous mounting of the seat cushion and guide elements in a single work step.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If guide elements are installed separately from the seat cushion after the seat cushion is mounted in the vehicle seat, then the guide elements can be installed individually, but the mounting process becomes time-consuming and complex
Solution Approach 1:
The guide element is merged with the seat cushion by providing a fastening element that connects the guide element to the seat cushion before mounting. This combining allows both components to be installed together in a single operation, eliminating the need for separate installation steps and reducing overall mounting time.
Solution Approach 2:
The guide element is pre-connected to the seat cushion using the fastening element with the oblong-hole-type opening and tab before the seat cushion is mounted in the vehicle seat. This preliminary action simplifies the final installation process and reduces the complexity of the mounting sequence.
2Adaptability or versatility
If guide elements are installed separately from the seat cushion, then individual installation is possible, but the mounting sequence becomes complicated
Solution Approach 1:
By merging the guide element with the seat cushion through the fastening element, the patent reduces the number of separate components that need to be handled during installation. This simplifies the mounting sequence from multiple discrete steps to a single integrated installation operation.
3Ease of operation
If a tab is used to connect the guide element to the seat cushion, then the connection is simple and easy to handle, but the fastening mechanism must be designed with an oblong-hole-type opening
Solution Approach 1:
The tab with the oblong-hole-type opening allows the guide element to be self-fastened to the seat cushion by simply inserting and pushing the tab through the opening. The oblong shape provides inherent alignment and retention features, allowing the connection to be made without additional fastening mechanisms or complex assembly steps.

AI summary
A ISOFIX guide element, having a base section, a rear side section, and two side sections connected to the base, an insertion opening, which is delimited by respective inner sides of the base section and the two side sections, a bracket opening formed between the base section and the rear side section which has notches formed in the side sections in such a way that a bracket-like fixing element can be accommodated in the notches, and that the fixing element is accessible through the insertion opening. It is provided here that at least one fastening element protruding from the base section is arranged on an outer side of the base section, wherein the fastening element has at least one oblong-hole-type fastening opening, which is connectable to a tab of a seat cushion or a seat cover of a vehicle seat.
