Introduction

The wheelchair and occupant limit system of the barrier-free bus is to provide safety requirements for wheelchairs and passengers in the barrier-free bus.

Set. At present, with the gradual development and improvement of barrier-free facilities in my country, wheelchairs and special space areas for passengers are gradually being used in public transportation.

Increasingly, it is particularly important to regulate the design and installation of wheelchairs and occupant limit systems. There are currently no

The wheelchair and occupant limit system of handicapped buses are mainly divided into two types, one is the rear-facing wheelchair occupant system, and the other is the forward-facing wheel.

Chair car occupant system. Therefore, GB/T 40887 "Wheelchair and occupant limit system for barrier-free passenger cars" is planned to be composed of two parts, aiming to confirm

The design and production of wheelchairs and occupant limit systems for barrier-free buses are required.

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

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

Part 1.Rear-facing wheelchair occupant system

1 Scope

This document is applicable to wheelchair occupant spaces used by rear-facing wheelchair occupants with a weight greater than 22kg on barrier-free passenger vehicles

(RF-WPS). It is a system suitable for vehicles traveling on a fixed route under normal and emergency driving conditions. Passengers can be seated and

Standing position. The prerequisite of this standard is that the maximum acceleration of the vehicle in any direction under emergency driving conditions does not exceed 1g.

This document specifies the design requirements, performance requirements and related test methods of the rear-facing wheelchair occupant system, the manufacturer's instructions

Requirements, warning information requirements for installers and users, as well as product labeling and test information requirements.

The main purpose of this document is to restrict rear-facing wheelchairs, including scooters with three or more wheels, which may cause dangerous collisions inside the vehicle.

A movement that hits or causes injury to other passengers.

The provisions of this document mainly apply to the complete RF-WPS, but the specified sub-clauses can be applied to separately sold parts and components.

It also applies to the specific functions of the parts and components to be replaced.
