Introduction

The wheelchair vehicle and passenger restraint system of the barrier-free bus is a device that provides safety requirements for wheelchair vehicles and passengers in the barrier-free bus.

set. At present, with the gradual development and improvement of barrier-free facilities in my country, wheelchair vehicles and passenger-only space areas in public transportation are gradually becoming more and more popular.

It is particularly important to standardize the design and installation of wheelchairs and passenger restraint systems. At present, there are no domestic and foreign

There are two main types of wheelchair and occupant restraint systems for handicapped passenger cars, one is a rear-facing wheelchair occupant system, and the other is a forward-facing wheelchair system.

Chair car occupant system. Therefore, GB/T 40887 "Wheelchair Vehicles and Passenger Restriction Systems for Barrier-Free Passenger Vehicles" is planned to be composed of two parts, aiming to ensure

Requirements for the design and production of wheelchairs and passenger restraint systems for barrier-free passenger cars.

--- Part 1.Rear-facing wheelchair occupant system;

--- Part 2.Forward-facing wheelchair occupant system.

Wheelchair and passenger restraint system for barrier-free passenger cars

Part 2.Forward-facing wheelchair occupant systems

1 Scope

This document specifies the design requirements, performance requirements and related test methods, information, markings and descriptions of forward-facing wheelchair occupant systems.

Statement requirements, test reports and declaration requirements.

This document applies to wheelchairs weighing more than 22kg in accessible coaches that travel on fixed routes and transport seated and standing passengers

The space used for the vehicle occupant to ride facing forward. The prerequisite for this document is the maximum acceleration of the vehicle in any direction in emergency driving conditions

Not more than 1g, and the acceleration rarely exceeds 3g in a frontal collision. In this document, the term "wheelchair" includes both manual wheelchairs and electric wheelchairs

cars, as well as three- and four-wheel scooters.

This document applies primarily to the full forward-facing wheelchair occupant space (FF-WPS), but specified sub-clauses may apply to separate

parts and assemblies sold, as well as intended replacement parts and assemblies for a specific function.
