Definitions

• Head guard preferably annular brow-band, and method for manufacturing such a head guard.
• the present invention relates to a head guard, pre ⁇ ferably in the form of an annular brow-band comprising a longitudinal, preferably annular unit, which completely or substantially is made of cellular plastic.
• the inven- 5 tion also relates to a method for manufacturing such a head guard.
• a head guard comprising plates of cellular plastic provided in a stock ⁇ ing of elastic material.
• the stocking is sewn together Q between the plates and it permits stretching of the head guard for adaptation thereof to the size of the head.
• a problem at such head guards is however that there are unprotected spaces between the plates and that the width of these unprotected spaces increases with the stretching 5 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 above entioned type. This is arrived at according to the invention by means of the characterizing Q features of claim 1.
• fig, 1 is a perspective view of the head guard accor ⁇ ding 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 for ⁇ ming part of the " head .guard of fig. 1 in extended condi ⁇ tion;
• fig, 4 is a view IV-IV of the cellular-plastic unit of fig. 3; fig.
• the illustrated head guard has the shape of an annu ⁇ lar brow-band 1, comprising a cellular-plastic unit 2 and a cover 3 of suitable material r e.g. a textile material, preferably in the form of a terry-cloth stocking.
• the cellu ⁇ lar-plastic unit 2 is entirely or substantially, made of a cellular-plastic material, e.g.
• the cellular-plastic unit 2 further comprises a longitudinal band of cellular plastic (see fig. 3), the end portions 6, 7 of which have been glued or otherwise put together to provide the annu ⁇ lar shape.
• the unit 2 of cellular plastic is provided with four adjustment portions 8, 9 and 10, 11 respectively.
• Each adjustment portion 8 or 9 inclu ⁇ des depressions 12, 13 provided in the cellular-plastic unit 2, wherebythe depressions 12, 13 protrude into said unit alternately from an inner side 14a and an outer side 14b respectively,- of the unit 2.
• the depressions 12 protrude from that inner side 14a of the cellular-plastic unit 2 which- s-adapted to face inwards towards the head 15 of the person wearing the head guard.
• the depressions 13 however r protrude from that outer side 14b which is adapted to face outwards 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.
• the adjustment portions 8, 9 have six such cellular-plastic pads 16, while the adjustment portions 10 and 11 include eight cellular-plastic pads 16.
• the depressions 12, 13 protrude into the cellular- -plastic unit 2 substantially in transverse direction relative to the longitudinal direction L of said unit 5 (see fig. 4) , and the cellular-plastic pads 16 also ex ⁇ tend substantially .in this transverse direction T (see fig. 4) relative to the longitudinal direction L.
• the unit 2 is made of an elastic cellular- -plastic material and the pads 16, as well as the connec- 10.
• ting portions 17 connecting said pads together also con ⁇ sist of such elastic material, the pads and the connec ⁇ ting portions permit a limited stretching or elongation of the unit 2 in its longitudinal direction.
• the depres ⁇ sions 12, 13 see to that the adjustment portions 8-11 5 provide less resistance to stretching of the cellular- -plastic unit 2 than other portions of the unit, but the degree of stretching is limited while the connecting por ⁇ tions 17 and the cellular-plastic pads 16 see tb that.
• said pads can not "lay down” such that they extend sub- 0 stantially in the longitudinal direction L of the cellu ⁇ lar-plastic unit 2 instead of substantially in its trans ⁇ verse direction TR.
• a maximally stretched adjustment por ⁇ tion 8 is shown in fig. 6, from which it appears that the cellular-plastic pads 16 of said adjustment portion 8 5 still extend substantially in the transverse direction TR.
• the adjustment portions 8-11 maintain the re- 5 quired protective effect when stretched, the adjustment portions are preferably maximally stretchable until their width B (see fig. 6) is reduced by half Bl at the most (see fig. 6) .
• the depressions 12, 13 are tapering preferably in the direction into the cellular-plastic unit 2. While e.g. the inner depressions 12 have such a shape, the inner side 14a of the length of the adjustment portions 8-11 in the 5 longitudinal direction of the cellular-plastic unit 2 may decrease by changing the shape of the cellular-plastic unit 2 such that the originally "gaping" depressions 12 are closed (see fig. 5) . This is advantageous since hereby, the head guard is better adapted to heads 15 of small size.
• the inner depressions 12 preferably have a length LI which is equal to or larger than half the width B of the adjustment portions 8-11 when said portions are not stretche
• the outer depressions 13 are preferably of a length L2 equal to or smaller than half the width B of ' the adjust-
• the pads 16 of cellular plastic are preferably as
• each cellular-plastic pad 16 preferably has an outer planar or substantially planar stopping portion 18a and an inner planar or substantially planar support
• the cellular-plastic unit 2 of the illustrated bro-H- band in the shape of a longitudinal strip comprises a protective portion 19 adapted for protecting the brow and positioned between the adjustment portions 8 and 9, two
• protective portions 20 and 21 for the temples positioned between the adjustment portions 8 and 10 and 9 and 11 respec tively, and a protective portion 22 for the back of the head defined by the end portions 6, 7 of the strip when attached to each other.
• These protective portions 19-22 preferably lack transverse or substantially transverse depressions and are therefore less elastic than the adjust ment portions 8-11.
• the strip preferably has the same 5 width B in unstretched condition, which means that the adjustment as well as protective portions 8-11 and 19-22 respectively, also have the same width B in unstretched condition.
• the cellular-plastic unit 2 is preferably pro vided with at least one longitudinal depression 23, which preferably extend along the entire or at least the major 5 part of the cellular-plastic unit 2.
• This, depression 23 protrudes into the cellular-plastic unit 2 from the out ⁇ side 14b thereof and it preferably has a length which is equal to or less than half the width B of said unit 2.
• This longitudinal depression 23 preferably extends Q in the center or substantially in the center of the cel ⁇ lular-plastic unit 2, whereby said unit easily "folds" somewhat in the middle in order to better adapt to the shape of the head 15.
• the cellular-plastic unit 2 and especially its adjust- ment portions 8-11 as well as the cover 3 permits folding of the brow-band (see fig. 8) so that it can be put away, e.g. in the pocket, when not used.
• the brow-band described above has a very low weight, is adaptable to heads of various size, follows exactly the shape of the head, sits firmly on the head, provides good protection therearound and is easy to fold and/or roll and put away after use.
• the head guard according to the invention may be manufactured in different ways, whereby an especially sui- table method of manufacture is carried out by pressing heated blades 24, 25 into a cellular-plastic unit 2 with preferably uniform width for providing depressions 12, 13 (see fig. 7) .
• Other portions of the cellular-plastic unit 2 are subjected to warm processing means 26, 27 such that said unit 2 gets a surface which is less porous than the parts lying within said surface. Due to this method the cellular-plastic unit 2 gets a protective surface which 5 successively, i.e. without a sharp transition, transcend into more porous parts of the unit within said surface.
• 10. 24 may e.g. " be formed by a heatable jaw 28 and the proces ⁇ sing means 27 and the blades 25 by another heatable jaw 29. These jaws 28, 29 are preferably moveable towards each other (see arrows 30 and 31 respectively in fig. 7) .
• the manufacturing proceeds in this case such that e.g. a cellu-
• the brow-band described above is a suitable variant of the head guard of the invention and the manufacture described above is advantageous in many ways.
• the invention may vary within the scope of the following
• certain parts of the cellular-plastic unit may be of another material than cellular plastic and/or another material e.g. of reinforcement steel may be embedded in the cellular plastic.
• the cellular-plastic material may be of another
• Each ad ⁇ justment portion may have an optional number of cellular- -plastic pads positioned beside each other and the number of adjustment portions may be one or more.
• the depressions may have another length than described above and the height and/or width of the cellular-plastic pads may be another than stated.
• the stopping and support por ⁇ tions of the cellular-plastic pads may also have another Q shape than described and their mutual position may even ⁇ tually vary from what is described.
• the cellular-plastic unit may have a uniform width in unstretched condition as stated, but its width may vary along its length if this is preferred in any embodi- 5 ment. In the same manner the height of the head guard may vary along its length.
• the head guard may be a brow-band with a cover of another suitable material and another suitable shape than a terry-cloth stocking.
• the head guard may alter- Q natively be an annular band provided in a cap which is fol ded around the band.
• the band is completely cove ⁇ red by the cap and have the same advantageous properties as a free-lying brow-band.
• the head guard forms part of a helmet which complete- ly or partially extends up above the head.
