‘Module-Based Seating System for Optimized Mobility Services’ The ‘Switch Mobility Seat’ is designed to be highly configurable, allowing for diverse combinations to meet the requirements of operators or users through simple functional arrangements. The modular structure allows users to freely select seat configurations based on their travel purposes and comfort preferences. The seat was designed based on comfort data to ensure a comfortable ride for passengers with varying physical conditions. By fixing seats in the 2-row wheelhouse, often referred to as the “gray zone”, and applying swivel/folding functions, they can be stored slimly on the vehicle’s wall, facilitating easy loading of strollers, wheelchairs, and cargo. The seat upholstery incorporates eco-friendly materials, including CO2-reducing, pollution-resistant artificial leather produced through a sustainable manufacturing process, and single-material recyclables designed for easy reproduction, promoting responsible disposal and resource recovery.
