Abstract
A guard element () for use in a hair cutting unit as a guard of a movable hair cutting element of the hair cutting unit has a disc-shaped base () and an annular wall () comprising a main part () extending from the periphery of the base (), and a flange-shaped part () comprising an outwardly bent section (). The annular wall () is reinforced on the basis of at least one of a design where a smallest inner periphery of the flange-shaped part () has a diameter which is smaller than a diameter of a largest inner periphery of a straight section () of the main part () connected to the periphery of the base (), and a design where a free end section () of the flange-shaped part () is at least partially bent. In an embodiment, at least a portion of the main wall part () of the guard element () tapers inwardly in a direction along a central axis () of the disc-shaped base (), from the disc-shaped base () to the flange-shaped wall part (), such that the flange-shaped wall part () is enlarged with respect to a flange-shaped wall part () of a guard element () not having the tapered shape of the main wall part (), resulting in increased stiffness and an increased resonant frequency of the guard element ().
