Glass fiber reinforced PA6 for the new injection molding seat back, 30% weight reduction 2023-04-10

√ The first lightweight third row freestanding seat back
√ Solution helps new cars lose 30% weight and save 15% cost over their predecessor

Lightweight parts have been successfully applied and applied to the new 2021 cars. The new model, due to go on sale in the second half of this year, has managed to reduce body weight with a lightweight component on the back of the third-row chair. The third-row back of the previous generation of cars was made up of 15 different steel components, and the body was very heavy. So hopefully the 2021 third row seats will meet all performance criteria while being lighter and more cost competitive.

"Being lighter does not necessarily mean being more expensive," the researchers said. Compared with the previous generation model, during the research and development of the new model, we not only achieved a 30% reduction in the weight of the third row seat, but also saved 15% of the cost. These goals are achieved because we have many great partners."

The resin parts of traditional car seats contain metal reinforcement, which increases the cost of the process. The hope is to obtain a whole injection parts without complex, expensive processing. To meet the requirements, an exclusive 35% fiberglass reinforced, impact-resistant modified polyamide PA6 product was used along with its proprietary computer simulation (CAE) tool that can be used in multiple stages of development.

"I classify the third row seat design of the 2021 Toyota Senna as an enabling technology," said the developer. It is the first all-injection molded seat back of its kind to be designed without any inserts, and one of the design challenges was to ensure the seat had high elongation and impact resistance to meet crash-avoidance requirements. "At the same time, we focused on the strength and stiffness of the seats, because the third row also supports the floor."
