Guide To: ECE R29 - Cabs of commercial vehicles

UN ECE R29, or Regulation No. 29 of the Economic Commission for Europe of the United Nations, is a regulation that specifies the requirements for head restraints for power-driven vehicles and their trailers. These devices are used to protect the occupants of vehicles from neck injuries in the event of a rear-end collision.

UN ECE R29 applies to head restraints that are either stand-alone or built into the seats of vehicles. The regulation specifies the size, shape, and performance of head restraints. It also specifies the test methods that must be used to verify that head restraints meet the requirements of the regulation.

UN ECE R29 is recognized by many countries around the world. This means that head restraints that have been approved under UN ECE R29 can be used on vehicles in these countries.

Here are some of the key requirements of UN ECE R29:

Head restraints must be adjustable to accommodate different occupants. Head restraints must be able to withstand a certain amount of force without deforming. Head restraints must be able to redirect the head of an occupant in the event of a rear-end collision. UN ECE R29 is an important regulation that helps to improve the safety of vehicles on the road. By requiring head restraints to meet certain standards, the regulation helps to ensure that these devices are effective in protecting occupants from neck injuries in the event of a rear-end collision.

Here are some additional points about UN ECE R29:

Head restraints must be located in the headrest mounting zone of the seat. Head restraints must be at least 70 mm high and 100 mm wide. Head restraints must be able to move up and down by at least 50 mm.
