Dynamic Automobile Passenger Seat for Enhanced Safety ID: 2021-029

An innovative passenger seat that dynamically adjusts its stiffness during rear-end collisions to enhance occupant safety.

Technology Overview

This technology introduces a novel automobile passenger seat designed to dynamically adjust its stiffness in the event of a rear-end collision, thereby enhancing the safety of the occupants. It employs an electric mechanism that alters the seatback's stiffness by adjusting the depth of a wedge in a groove near the seat's hinge. This adjustment is based on key parameters such as the occupant's weight, the velocity change during the crash, and the presence of rear occupants, with the aim of optimizing the seatback's stiffness to either absorb more energy or protect rear occupants by limiting deformation.

Key Advantages

• Enhanced safety in various crash scenarios
• Customizable stiffness based on real-time crash data
• Optimized protection for both front and rear occupants
• Utilizes existing vehicle crash data systems for smart adjustments

Problems Addressed

• Reduces the risk of injury in rear-end collisions
• Addresses the limitation of fixed-stiffness seats in adapting to different crash severities
• Improves upon passive seat designs with active stiffness modulation

Market Applications

• Automotive manufacturing
• Vehicle safety systems
• Passenger car market
• Commercial vehicle market
