Bristles for a hairbrush

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS A bristle of the present invention (FIG.
1) includes a bristle base 3 and a bristle head 5, with the possibility existing for the lower part of the bristle base 3 to be configured as a bristle strip inserted into a recess of a bristle supporting structure 7 or a brush.
It will be understood, of course, that a bristle may also be integrally formed with a bristle strip inserted into a hairbrush preferably parallel to the brush longitudinal axis.
In longitudinal section, the bristle 1 has the shape similar to that of a lozenge or rhombus with a section with the smallest cross-sectional area 9 being provided at the bristle base 3 above the bristle supporting structure 7.
The section with the largest cross-sectional area 11 is provided above the bristle base 3, a transition area 13 separating it from the smallest cross-sectional area 9.
This produces a neck portion 17 between the section with the largest cross-sectional area 11 and the surface of the bristle supporting structure 7.
Owing to the inclination of the transition area 13 relative to the surface of the bristle supporting structure 7, the brushing action causes the hair trapped by the neck portion 17 to be guided onto the-usually hot-surface of the bristle supporting structure 7.
This results in an improved and direct contact of the hair to be treated with the hot surface of the bristle supporting structure 7.
Bristle 1 has length 15 in the direction of bristle longitudinal axis 16.
A bristle 19 (FIG.
2) comprises a bristle base 21 to which adjoins a lower bristle portion corresponding to the bristle 1 and an upper bristle portion, with the upper end of the lower bristle portion continuing in a pin-shaped extension 25 having at its upper end a spherical thickened portion 27 representing the bristle head 23.
bristle 29 (FIG.
3) shows an alternative to the embodiment of FIG.
1.
Adjoining the bristle base 31 is a circular bristle with a maximum cross-sectional area 33.
In this embodiment, the transition area 35 between the bristle base 31 and the maximum cross-sectional area 33 is of an arcuate configuration
