AI Technical Summary

Technical Problem

Traditional air pressure adaptive shock absorption seat bases are difficult to install in confined spaces, the airbags are prone to tearing or leaking during violent rebounds, and fastener assembly is difficult, failing to meet the requirements of low-profile and flexible upper limit for special vehicle drivers.

Method used

The design incorporates a combination of a scissor bar mechanism, a limiting webbing, and a C-shaped fixing plate. The roller sliding stroke of the scissor bar mechanism is integrated into the vertical space formed by the bending of the vibration-damping top cover and the base. The limiting webbing is connected by a C-shaped fixing plate buckle, achieving a low-profile integrated layout and flexible upper limit. The rubber limiting block provides elastic support.

Benefits of technology

It enables low-profile installation in environments with limited vertical space, avoiding additional stacking height, ensuring the reliability and flexibility of the airbag components, preventing over-inflation failure, and meeting ergonomic comfort requirements.

Abstract

This invention belongs to the field of vehicle seat vibration damping technology, and particularly relates to a low-profile seat airbag suspension vibration damping structure. This invention provides a low-profile seat airbag suspension vibration damping structure, which, by setting a scissor bar mechanism, a main airbag assembly, a limiting webbing, a C-shaped fixing plate, and a C-shaped groove on the vibration damping top cover and vibration damping base, achieves the following: 1. By integrating the roller sliding stroke of the scissor bar mechanism into the vertical space formed by the bending of the vibration damping top cover and vibration damping base, additional stacking height is avoided, achieving a low-profile integrated layout suitable for installation environments with limited vertical space; 2. The limiting webbing is fastened to the C-shaped groove of the C-shaped fixing plate at both ends, allowing for quick assembly in confined rear spaces without fasteners. Furthermore, the groove wall clamps and locks under tension, preventing dislodgement and achieving long-term reliable flexible upper limit positioning, thus preventing the main airbag assembly from over-expanding and failing.
