A rectangular bristle substrate with a concave shape is also disclosed herein.

French Abstract

La brosse à cheveux comprend un élément allongé dont un segment forme une poignée et un autre segment supporte les poils. Le substrat supportant les poils définit un centre cylindrique avec une région centrale concave à courbe douce et des régions d'extrémité radialement plus larges. Une pluralité de poils sont attachées au substrat qui supporte les poils. Dans un mode de réalisation préféré, les poils sont de longueur essentiellement égale de sorte que les parties périphériques externes de la pluralité de poils définissent une forme concave à courbe douce complémentaire à la partie centrale concave du substrat qui supporte les poils. Les poils sont en outre segmentés en groupe de petits faisceaux et ces faisceaux sont disposés sur la surface périphérique du substrat qui supporte les poils dans une série. Chaque série de faisceaux de poils est espacée axialement dans un plan radial commun qui passe par la ligne de l'axe central de la brosse. Un substrat rectangulaire supportant les poils avec une forme concave est également décrit.

circumferential or angular offset between adjacent radial row of bristles
reduces the force
necessary to pass the brush through the hair of the user, enables faster
drying of the hair
with a blow dryer and requires less heat to blow-dry the hair. Further, the
hourglass
shape of concave central region 16 (FIG 3) enables faster blow drying time,
less heat and
less effort to brush the user's hair. The brush also gives the hair styles
more volume.
The angular offset between radial rows also enhances massaging of the scalp
during a
brushing session.
Hair brush 12 is anatomically configured such that the hourglass shape of
curved
concave central region 16 (FIG 3) generally matches curves on the user" head.
Handle segment 14 has a continuously curved convex region 40 and radially
smaller
end regions 42,44.
The bristles have substantially equivalent lengths 46 such that the outer
periphery of a
row of bristles defines a smooth curved concave shape about central region 50
that is
complementary the hourglass shape 16 of bristle substrate 14.
FIG4. Diagrammatically illustrates hair brush 12 with an elongated, generally
rectangular member 44. A cross-sectional aspect of member 44, from the
perspective
of section line 80'-80", is generally rectangular in shape. This generally
