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. The clamping member comprises a hollow interior with a tapering part, which tapers in a direction away from the holding member, and a second locking member, wherein the tapering part and the second locking member are axially separated. |

1. Height adjustment arrangement for an ear cup in a hearing protector unit, the height adjustment arrangement comprising:
an elongated member adapted to be coupled in a first end to a head mounting portion of a hearing protector unit, and a tubular holding member connected to the elongated member, the tubular holding member being adapted to be coupled in a first end to an ear cup, wherein the tubular holding member provides a substantially hollow interior for receiving a second end of the elongated member, wherein a relative movement between the elongated member and the tubular holding member provides a height adjustment of an ear cup relative to a head mounting portion, and a clamping member, wherein the clamping member is arranged to be moved from an unlocked position, in which position relative movement between the elongated member and the tubular holding member is enabled, to a locking position, in which position relative movement between the elongated member and the tubular holding member is prevented, wherein the clamping member is adapted to, when in the locking position, be attached to the tubular holding member such that the clamping member presses a second end of the tubular holding member towards the elongated member to prevent relative movement between the elongated member and the tubular holding member, characterized in that the tubular holding member comprises a first locking member, wherein the second end of the tubular holding member is provided with two flanges tapering in a direction towards the clamping member and wherein the first locking member and the flanges are axially separated, the clamping member comprises a hollow interior with a tapering part which tapers in a direction away from the tubular holding member and a second locking member, wherein the tapering part and the second locking member are axially separated, wherein, when the clamping member is moved from the unlocked position to the locking position, the second locking member a is arranged to integrate with the first locking member and the tapering part is arranged to press the flanges towards the elongated member. |
