PCT No. PCT/SE87/00592 Sec. 371 Date Aug. 11, 1988 Sec. 102(e) Date Aug. 11, 1988 PCT Filed Dec. 11, 1987 PCT Pub. No. WO88/04188 PCT Pub. Date Jun. 16, 1988.A head guard, preferably annular brow-band, comprising a longitudinal, preferably annular unit (2) which completely or substantially is made of cellular plastic. In order to ensure that all parts of the head guard provide adequate protection, the cellular-plastic unit (2) has depressions (12, 13) which protrude into the cellular-plastic material alternately from an inner side (14a) and an outer side (14b) respectively, of the unit, which inner side (14a) and outer side (14b) respectively, faces inwardly towards and outwardly from the head (15) respectively, whereby the depressions (12, 13) define cellular-plastic pads (16) with shock-absorbing properties and extending substantially transverse to the longitudinal direction (L) of the cellular-plastic unit (2) and whereby the cellular-plastic pads (16) and the connecting portions (17) connecting the pads together permit a limited stretching or elongation of the cellular-plastic unit (2) in its longitudinal direction (L) for providing at least one elastic portion (8-11) for adaptation to the size and/or shape of the cellular-plastic unit (2) and to the size and/or shape of the head (15) (FIG. 2). A simple and efficient method for manufacturing the cellular-plastic unit (2), includes pressing heated blades (24, 25) into the cellular-plastic unit (2) to provide depressions (12, 13) therein and bringing warm processing devices in contact with other parts of the cellular-plastic unit such that the unit receives a surface which is less porous than the portion disposed below the surface.

I claim:
1. A head guard in the form of an annular brow-band comprising:
- (a) a longitudinal annular unit including an inner side and an outer side;
- (b) a plurality of adjustment portions longitudinally spaced along the annular unit;
- (c) each adjustment portion being at least substantially entirely formed of cellular plastic and including a plurality of first depressions protruding inwardly from the outer side and a plurality of second depressions protruding outwardly from the inner side, the first and second depressions alternating with each other to define a plurality of pads therebetween;
- (d) the pads extending substantially transversely of the annular unit and including connection portions connecting adjacent pads together to permit a limited stretching of each adjustment portion in the longitudinal direction for conforming the annular unit to the size and shape of a head; and
- (e) each pad including a substantially planar stopping portion on the outer side and a corresponding substantially planar support portion on the inner side, with at least a part of the stopping portion being positioned directly opposite a part of the support portion to impart a protective shock absorbing capability to the pad.
