Abstract: The present disclosure relates to a height adjustment arrangement (100) for an ear cup in a hearing protector unit, wherein the height adjustment arrangement (100) comprises an elongated member (130) and a tubular holding member (110) connected to the elongated member, wherein the holding member provides a substantially hollow interior (111). The height adjustment arrangement further comprises a clamping member (120), wherein the clamping member is arranged to be moved from an unlocked position, in which position relative movement between the elongated member (130) and the holding member (110) is enabled, to a locking position, in which position relative movement between the elongated member and the holding member is prevented. The holding member (110) comprises a first locking member (114), wherein the second end of the holding member is provided with two flanges (115a, 115b) tapering in a direction towards the clamping member, and wherein the first locking member and the flanges are axially separated.

Abstract: Example embodiments relate to an ear cup for use in a hearing protector unit including two ear cups, and a device to fasten the hearing protector unit to a wearer' s head, the device being connected to the ear cups. The ear cup may include a cup portion with a support surface; and a sealing device, placed against the support surface of the cup portion and intended to bear against a wearer' s head in an area around an ear of the wearer.

Abstract: A system for forming hearing protectors, an ear cup of such a system and a hearing protector formed from such a system. The system includes a number of first ear cups and a number of second ear cups, the first and second ear cups having noise-reducing spaces of different size, and at least one electronic unit with at least one speaker. This system allows the same type of electronic unit to be used for ear cups with different degrees of noise attenuation.

Abstract: The invention concerns a system for forming hearing protectors, an ear cup of such a system and a hearing protector formed from such a system. The system comprises a number of first ear cups (5a) and a number of second ear cups (5b), the first and second ear cups having noise-reducing spaces (11) of different size, and at least one electronic unit (30) with at least one speaker (31). An inner distance (I3) in the noise-reducing space from the speaker (31) in the direction away from the noise-reducing space, and a volume (V3) of a resonance space (15) in the first ear cup are adapted to the inner distance (Ib) and the volume (Vb) of the resonance space (15) in the second ear cup (5b). This is done in such a manner that, when the electronic unit is mounted in each ear cup, sound emitted by the speaker (31) in each ear cup produces substantially the same sound characteristic from the first ear cup (5a) as that from the second ear cup (5b).

Abstract: An ear cup (1) has a cup portion (I?) with a support surface (3), as well as a sealing device (4), which is placed against the support surface of the cup portion for bearing against a wearer's head in an area around an ear of the wearer. The sealing device (4) comprises a sealing portion (5) of a soft material, which in its periphery area bears against said support surface (3), and a clamping ring (7) of a hard material, which expands the sealing portion (5). The sealing portion (5) is provided with a peripherally extending flange, which is introduced in the cup portion (1?) and bears against the inner side of the cup portion, whereby the clamping ring (7) bears against the flange and presses the flange against the inner side of the cup portion (1?) for fastening the sealing device (4) to the cup portion (I?).

Abstract: A floor sander is disclosed that includes a drum having an outer surface formed from a number of units shaped like the frustrum of a sector, each having a first end receivable in a groove on the outer surface of an inner drum member so that, if the surface of the drum is damaged, one or more units can be replaced individually instead of replacing the entire drum or outer drum surface.

Abstract: A disposable absorbent article, such as a diaper, an incontinence guard or the like, includes an inner, liquid-permeable casing sheet, which when the article is worn lies nearest the body of the wearer, an outer, liquid-impermeable casing sheet, an absorbent pad enclosed between the two casing sheets, and a layer of fibre wadding disposed between the absorbent pad and the inner casing sheet. The inner casing sheet is joined to the absorbent pad along two longitudinal lines forming permanent fold lines which divide the article, over at least a part thereof, into a central elongated part and two edge-parts located symmetrically on respective sides of the central elongated part. Each edge-part is folded between the respective fold line and its lateral edge such as to form an inwardly upstanding longitudinal fold in the outer casing sheet.
