Urban electric mobility is transforming the design of commercial vehicles. In this context, Paxster—a Norwegian manufacturer specializing in compact electric vehicles for last-mile logistics—trusted GSB to develop the seatbelt system for its platform.

The objective was clear: to integrate a safe, certified and perfectly adapted restraint solution into a compact cabin, designed to maximize energy efficiency and withstand intensive daily use.

The technical challenge in compact electric vehicles

Electric urban delivery vehicles have very specific technical constraints. In the case of the Paxster, its lightweight architecture and small dimensions limited the space available for integrating the anchor points and the retractor system.

Furthermore, the vehicle is designed for intensive use with multiple daily stops, constant operation in urban environments, and exposure to demanding weather conditions, especially in Northern European markets. Added to this was the need to comply with international regulations for its sale in various countries.

The belt system had to be fully integrated into the vehicle structure without compromising driver ergonomics or the efficiency of the OEM manufacturing process.

Application engineering: the solution developed by GSB

From the initial phases of the project, GSB’s engineering team worked closely with Paxster to develop a specific solution for its electric platform.

The process included a detailed analysis of the seat geometry and available structural anchor points. The optimal length and travel of the strap were defined to ensure freedom of movement during urban riding while maintaining a secure fit. The most suitable retraction system for the intended use was also selected, and its integration into the OEM manufacturing process was optimized.

The result was a seatbelt fully adapted to the vehicle’s architecture, guaranteeing functionality, safety and ease of assembly on the production line.

Certified safety and international regulatory compliance

The solution developed meets and/or exceeds internationally recognized standards, including:

• SAE J386

• FMVSS 209

• FMVSS 302

• ECE R16

Beyond regulatory compliance, the design prioritized durability in professional fleet environments. The system offers high wear resistance, long-term mechanical reliability, and consistent performance even in cold climates—key factors in intensive urban delivery applications.

Project results

Thanks to this technical collaboration, Paxster was able to integrate an optimized safety solution specifically for its light electric vehicle. Regulatory compliance was ensured in various international markets, driver ergonomics and comfort were maintained, and the vehicle’s overall reliability in professional applications was enhanced.

This project demonstrates how application-specific engineering is a decisive element in the development of restraint systems for light electric vehicles and special platforms.
