98. Head restraints

Head restraints, also called headrests, are vehicle safety devices designed to limit the rearward movement of an occupant's head relative to the body during a collision. They help reduce the risk of injuries to the neck and cervical spine, particularly in rear impacts.

An adjustable head restraint should be positioned so that it supports the back of the head rather than the neck and is as close to the head as practical. Drivers and passengers should adjust the restraint to their body size before travelling.

What is the purpose of a head restraint?

A head restraint limits excessive rearward movement of the head during a collision, helping reduce the forces acting on the neck and cervical spine.

How should a head restraint be adjusted?

It should be adjusted to support the back of the head rather than the neck and positioned as close to the head as practical. The seat and head restraint should be adjusted together to provide a comfortable and protective driving position.

Are head restraints part of passive safety?

Yes. Head restraints are passive safety devices because their main purpose is to reduce injury when a collision occurs rather than to prevent the collision itself.
