Abstract
A pad for a forehead support includes an outer wall having a first side configured to engage a user's forehead and a second side having engaged surfaces configured to rest against engaging surfaces of the forehead support; at least one retaining wall provided between the first side and the second side; and at least one retained portion configured to be retained by a retainer formed on the forehead support, wherein a space is defined between the outer wall and the engaged surfaces. The space has a substantially constant cross sectional profile, and the outer wall, the at least one retaining wall, and the engaged surfaces are formed of a deformable elastomeric material. Deformation of the pad occurs by deflection of at least the outer wall and the at least one retaining wall.
