DESCRIPTION:
BRIEF SUMMARY
The present invention relates to a head guard, preferably in the form of an annular brow-band comprising a longitudinal, preferably annular unit, which is completely or substantially completely made of cellular plastic. The invention also relates to a method for manufacturing such a head guard.
In DE-A1-30 05 001 there is described a head guard comprising plates of cellular plastic provided in a stocking of elastic material. The stocking is sewn together between the plates and permits stretching of the head guard for adaptation thereof to the size of the head. A problem of such head guards is that there are unprotected spaces between the plates and the width of these unprotected spaces increases with the stretching of the head guard.
The object of the present invention is to eliminate this problem and to obviate unprotected spaces at head guards of the abovementioned type.
Another object is to provide a simple and efficient method for manufacturing the head guard of the invention.
The invention shall be further described below with reference to the accompanying drawings, in which
FIG. 1 is a perspective view of the head guard according to the invention in the form of an annular brow-band placed in working position around the head of a person;
FIG. 2 is an enlarged view of the head guard of FIG. 1;
FIG. 3 is a plan view of a cellular-plastic unit forming part of the head guard of FIG. 1 in extended condition;
FIG. 4 is a view IV--IV of the cellular-plastic unit of FIG. 3;
FIG. 5 is a section V--V through the head guard of FIG. 2;
FIG. 6 is a section corresponding to FIG. 5 through the head guard in a more stretched condition;
FIG. 7 illustrates a portion of the cellular-plastic unit forming part of the head guard during a manufacturing step; and
FIG. 8 illustrates the head guard of FIG. 1 in a folded condition.
The illustrated head guard has the shape of an annular brow-band 1, comprising a cellular-plastic unit 2 and a cover 3 of suitable material, e.g. a textile material, preferably in the form of a terry-cloth stocking. The cellular-plastic unit 2 is entirely or substantially entirely made of a cellular-plastic material, e.g. polyethylene, whereby the inner portions 4 of the unit 2 preferably consist of expanded polyethylene and a surface 5 of unexpanded polyethylene or polyethylene which is made less porous than said inner portions 4. The cellular-plastic unit 2 further comprises a longitudinal band of cellular plastic (see FIG. 3), the end porions 6, 7 of which have been glued or otherwise secured together to provide the annular shape. In the embodiment shown, the unit 2 of cellular plastic is provided with four adjustment portions 8, 9 and 10, 11 respectively. Each adjustment portion 8 or 9 includes depressions 12, 13 provided in the cellular-plastic unit 2, whereby the depressions 12, 13 protrude into said unit alternately from an inner side 14a and an outer side 14b respectively, of the unit 2. Thus, the depressions 12 protrude from that inner side 14a of the cellular-plastic unit 2 which is adapted to face inwardly towards the head 15 of the person wearing the head guard. The depressions 13 however, protrude from that outer side 14b which is adapted to face outwardly from the head 15. The depressions 12, 13 define pads 16 of cellular plastic, whereby each pair of adjacent depressions 12, 13 defines a cellular-plastic pad 16. Thus, the adjustment portions 8, 9 each have six such cellular-plastic pads 16, while the adjustment portions 10 and 11 each include eight cellular-plastic pads 16. The depressions 12, 13 protrude into the cellular-plastic unit 2 substantially in a transverse direction relative to the longitudinal direction L of said unit (see FIG. 4), and the cellular-plastic pads 16 also extend substantially in this transverse direction T (see FIG. 4) relative to the longitudinal direction L.
Since the unit 2 is made of an elastic cellular-plastic material and the pads 16, as well as the connecting portions 17 connecting said pads together also consist of such elastic material, the pads and t
