Helmet Wearing Height Testing Machine

The helmet wearing height testing machine is a testing device used to evaluate the comfort and safety performance of helmets. It precisely measures the wearing height parameters to ensure that the helmet fits the human head according to design requirements. In the manufacturing process, manufacturers use this device to quantitatively test helmet samples, verifying whether the vertical distance between the headband, liner, and the top of the head is reasonable.

Application

Measure the wearing height of helmets to ensure the accuracy and safety of helmet - wearing positions.

Test Procedures

Select the head form: According to the standard, use head form #1 when the wearing height is ≤85mm; use head form #2 when the wearing height is >85mm.

Install the digital scale: Fix the digital scale to the selected head form using the provided mounting holes.

Zero the scale: Pull the digital scale to the bottom and press the zero button.

Adjust the measuring caliper: Measure the distance between the side straps of the helmet and adjust the measuring caliper to the appropriate length.

Wear the helmet: Place the helmet normally on the selected head form.

Read the value: Pull the digital scale until the measuring caliper touches the side straps, and read the value B1.

Calculate the wearing height: Subtract B1 from 280 to obtain the helmet wearing height.
