Tesla has submitted a patent application for a “fibrous foam architecture” with claims that the manufacturing technique for seats and interior trim would create a more efficient and environmentally-sustainable process.

The submitted patent explains that the current materials used for cushioning in traditional vehicle seats include foam made from polyurethane, a material that is not able to be recycled and may not be the most comfortable due to its lack of breathability. Manufacturing the foam is also a time-consuming and laborious process that involves the pouring and mixing of numerous chemicals, like polymer or epoxy, into a mold. After setting, this requires additional material to be trimmed and shaped, thereby creating unnecessary waste that Tesla’s fibrous foam architecture hopes to eliminate.

The background of the patent states, “Trim to foam assembly may include hog ring, hook and loop, and/or clipping methods. In such methods, alignment tolerances may need to be maintained, mating surface limitations may need to be met, trenches and stitches may need to be provided and so on. Glue application storage and handling may also be required. Current manufacturing processes may be labor-intensive and time-consuming.” This would improve the production and quality of backrests, armrests, leg-rests, and bolsters.

Tesla is looking to improve upon its vehicle’s interior, as it suggests “there is a need for an improved foam architecture and associated manufacturing process that overcome the aforementioned drawbacks.”
