Introduction
Research on the safety performance of transportation vehicles has shown that the design of motor vehicle seats, fixed equipment and seat spacing in motor vehicles, in
When a motor vehicle collides, it will play a key role in protecting the occupants. It is impossible for motor vehicle manufacturers to change the seat, so for some wheelchairs
For car users, they must sit in a wheelchair when traveling in a motor vehicle. GB/T 18029.19 provides design evaluation of wheelchairs
Method and method for evaluating the frontal collision avoidance performance when the wheelchair is used as a front-facing seat in a motor vehicle and is subjected to a frontal impact.
However, it is usually assembled into a complete wheelchair with a seat produced by one manufacturer and a frame produced by another manufacturer. Wheelchair
The seat system can also be used in various wheelchairs. Therefore, it is necessary to be able to install wheelchair frames on wheelchairs and independently sell wheelchair frames from the market.
The design and performance of the seat system are evaluated. This document provides the use of wheelchair alternatives to evaluate the frontal impact of a seat system without a frame
The method of anti-collision performance at the time. GB/T 30661 is intended to be composed of four parts.
---Part 1.Vocabulary, reference axis and measurement of body parts, posture and posture supporting surface.
---Part 2.Determination of the physical and mechanical properties of the device to maintain tissue integrity.
---Part 3.Determination of static, impact and fatigue strength of postural support devices.
---Part 4.Seat systems used in motor vehicles.
The manufacturer may not test customer-specific seating systems. The manufacturer may test a representative seat system and
This proves that the test results are applicable to the scope of use of the product and the product specification.
The purpose of this document is to enhance the practicality of wheelchair seats based on protecting the safety of users, so as to improve wheelchair transportation.
Security. This document should not prohibit or restrict wheelchair users from using transportation.
At present, this document only proposes the requirements for a complete set of wheelchair seat systems, and the testing requirements are typical frontal impact conditions. However, future editions
This meeting proposes the detection of individual components of the seat system and the detection of impacts in other directions (such as side or back).
Wheelchair seat
Part 4.Seat systems used in motor vehicles
1 Scope
This document specifies the design of the seat fixing system for front-facing seats installed on motor vehicles and manual or electric wheelchairs.
Design, performance requirements and test methods, as well as requirements for identification, labeling, instructions for use, warnings and information release. This document can assess passengers
It is the frontal collision avoidance performance of the seat system for adults or children weighing no less than 22kg.
This document is only applicable to the four-point strap fastening device that is used with the wheelchair chassis that meets the performance requirements of ISO 7176-19.
A complete wheelchair seat system including connecting hardware.
This document is suitable for use with the occupant safety limit system (fixed to the motor vehicle, securing system or wheelchair frame)
Seat system.
Seating systems that are only used for specific wheelchair chassis should meet the requirements of ISO 7176-19.
