ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a protective helmet.
2. Description of Background and Relevant Information
In a known fashion, a helmet generally includes an outer cap, a protective padding, a comfort padding, and a retaining system.
Essentially, a helmet is provided to protect the user's head. Under these conditions, the cap of the helmet can be subject to strikes or impacts. The helmet can also receive impacts when it is being handled.
Sometimes, the helmet can be used successively by various users. This is the case, for example, when the helmet is lent or rented with equipment to practice a given sport.
Under such a circumstance, it is difficult for the user or renter to be aware of the treatment to which the helmet has been subject previously.
In particular, the helmet may have received a previous substantial impact that renders it inadequate for another use as a protective helmet.
As a result, existing helmets are not completely reliable.
SUMMARY OF THE INVENTION
An object of the present invention is to increase the reliability of the currently known helmets.
To this end, the helmet according to the invention has a protective cap. The cap is equipped, at least locally, with at least one visual impact indicator.
The expression “visual impact indicator” is intended to refer to an element whose state or color changes subsequent to an impact exceeding a predetermined threshold. By noticing this change of state or color, the owner, renter or user is warned that the subject helmet can no longer be used as a protective helmet.
