A half-mask respirator is retained on a wearer's head by upper and lower straps and a strap support. The upper and lower straps connect to the strap support at upper and lower strap attachment points on each side of the strap support. The distances between the attachment points on each opposing side of the strap support are fixed when the strap support is located on the wearer's skull and the half-mask respirator is mounted over the wearer's nose and mouth. As a result, the lower strap is supported above the neck of the wearer which eliminates a potential source of discomfort for the wearer.
Selon l'invention, un demi-masque respiratoire est retenu sur la tête d'un porteur par des sangles supérieure et inférieure et par un support de sangles. Les sangles supérieure et inférieure sont fixées au support de sangles par des points d'attache disposés de chaque côté du support de sangles. Les distances entre les points d'attache situés sur chaque côté opposé du support de sangles sont fixés lorsque le ce dernier est placé sur le crâne du porteur et que le demi-masque respiratoire est placé sur le nez et la bouche du porteur. Ainsi, la sangle inférieure est portée au-dessus du cou du porteur, ce qui élimine une source potentielle d'inconfort pour le porteur.
