Revo, Snoeks Automotive
Revo improves the comfort in the crew cab by making the backrest angle adjustable for each individual passenger. Bringing different mechanical and structural challanges. Final design in tested and validated in the industry standard R14 pulling test.
Develop a new backrow seat system with extra functionalities and comfort. The most important one being the backrest angle.
The Problem
The current frame features both an upper and lower crossmember, which prevents adjustment of the backrest angle. In addition, due to fiscal regulations, an imaginary block must fit behind the middle seat in order to qualify for tax benefits.
The solution
The two cross members are replaced with one circular crossmember in the middle. This allows the backrest angle to be adjustable. Different backrest sizes can be connected to the frame. Creating a modular system and reducing custom parts for different size panel vans.
The beam
Where the original frame has two cross-members to support the seatbelt assembly, this frame has one cross-member, allowing the backrest to fold forward and to make it more modular.
The backrest
We 3D scanned several users to design the ultimate backrest shape. Allowing for a decrease in foam thickness and thus weight of the assembly.
The mechanism
The mechanism allows the backrest to pivot.
Modulairity
Panel vans differ in width, currently every bench assembly uses different parts. Standardizing this with one system allows for cheaper implementation cost.
Testing and Validating
One of the most inspiring experiences during this project was the testing phase. The client Snoeks Automotive could conduct in-house certified R14 pulling tests. As a team we created two test setups, the central cross member alone (A) and one individual seat with seatbelts (B). This gave us more insights in critical failure points.
The results
The results of the setup were impressive. While there is room for improvement, achieving a force of 91.4% is quite notable for an 18-week project. The company is currently working on further developing this concept.
Key Project Insights
The complexity of FAE simulations.
100% group work led to significant learning in communication and teamwork.
My passion for mechanical engineering.
Always consult with people on the work floor/users; don’t rely solely on intermediate opinions.
