Patented Alternative Load Path Technology™ (ALPT™)

All Leatt-Braces® help protect riders from 5 types of head/neck impacts by employing Alternative Load Path Technology™. This innovation helps disperse the energy, typically transferred to the neck, resulting from an impact to the head* and assists in the transferring of forces away from the vulnerable neck structures to less vulnerable areas of the body and is pivotal in the design of all Leatt-Braces®.

How does ALPT™ work?

In a typical face-plant type accident without a Leatt-Brace®, the force of the impact is transferred from the ground to the helmet, through the helmet to the scull and scull base where it is then transferred through the neck to the back (thoracic spine). With the Leatt-Brace® fitted, the force will instead transfer from the ground to the helmet, through the helmet onto the Leatt-Brace® once contact is made, some of the force will therefore be transferred to the brace and dispersed to the less vulnerable parts of the torso. If the impact is significant enough, the brace is designed to fail in crumple zones (similar to those seen in cars), thereby helping to absorb some of the energy of the impact.

What dynamics does the Leatt-Brace® help protect against?

The Leatt-Brace® helps protect against the following main scenarios:

• Hyperextension: Extreme bending of the head in a rearward direction
• Hyperflexion: Extreme bending of the head in a forward direction
• Lateral Hyperflexion: Extreme bending of the head to one side
• Posterior Hypertranslation: Movement of the head relative to the neck, at ninety degrees to the neck.
• Coupled Axial Loading: Helps prevent axial loading only when the axial forces act in combination with other mechanisms. As an example, this typically occurs when your head is forced downward and forward (Hyperflexion) or downward and backward (Hyperextension).

*While wearing a full-face helmet, excluding certain scenarios.
