In the exemplary embodiment the item of protective equipment 16a is realized as safety eyewear. It is also conceivable, however, for the item of protective equipment 16a to be realized as a jacket, as trousers, as a helmet, as work shoes, as a waistcoat, as a glove or the like. In the embodiment according to the invention, the protective equipment element 18b has a sending unit for sending an ID, and has an energy storage unit. In the embodiment, the hand-held power tool 14a is a battery-operated hand-held power tool 14a having a rechargeable battery 20. The mobile functional unit 22 is arranged between the rechargeable battery 20 and the hand-held power tool 14a, at an interface of the hand-held power tool 14a to the rechargeable battery 20.

[0019] An operator 21 wears the item of protective equipment 16a and carries the hand-held power tool 14a.

[0020] Furthermore, the system may include the following components, the list being non-exhaustive: [0021] a second hand-held power tool 14ab [0022] a second item of protective equipment 16b, comprising a second protective equipment element 18b [0023] a multiplicity of hand-held power tools [0024] a multiplicity of items of protective equipment, comprising a multiplicity of protective equipment elements

[0025] The item of protective equipment 16b is realized as a jacket. It is also conceivable, however, for the item of protective equipment 16a to be realized as protective work eyewear, as trousers, as a helmet, as work shoes, as a waistcoat, as a glove or the like. In the embodiment according to the invention, the protective equipment element 18b has a sending unit for sending an ID, and has an energy storage unit. The hand-held power tool 14b is a mains-operated hand-held power tool 14b having a mains-power cable 24. A mobile functional unit 22 is arranged at the interface of the mains-power cable 24 of the hand-held power tool 14b to the mains energy supply system.

[0026] In a third embodiment, the mobile functional unit 22 is integrated in the hand-held power tool 14c (FIG. 1).

[0027] The method according to the invention for the enabling of at least one active operating state of a hand-held power tool 14a, 14b, 14c by at least one mobile functional unit in dependence on whether an item of protective equipment 16a is carried and/or worn by an operator of the hand-held power tool can proceed in differing variants, and is described in the following exemplary embodiments.

[0028] FIG. 2 shows that, in a first method step 100, the ID of the first protective equipment element 18a of the first item of protective equipment 16a is sent to the mobile functional unit 22. The mobile functional unit 22 receives the ID of the first protective equipment element 18a of the first item of protective equipment 16a. In a second method step 110, the mobile functional unit 22 enables an active operating state of the hand-held power tool 14a, 14b, 14c, in that an electrical power supply for the hand-held power tool 14a, 14b, 14c is activated.

[0029] In a further method step 120, the mobile functional unit receives the ID of the second protective equipment element 18b of the item of protective equipment 16b.

[0030] In a further method step 130, the mobile functional unit 22, upon receiving the first ID of the first protective equipment element 18a of the first item of protective equipment 16a and the second ID of the second protective equipment element 18b of the second item of protective equipment 16b, enables an active operating state of the hand-held power tool 14a, 14b, 14c, in that an electrical energy supply for the hand-held power tool 14a, 14b, 14c is activated.

[0031] The mobile functional unit 22 is equipped with a data storage unit 30. The data storage unit 30 is designed to store a list of all IDs of the protective equipment elements 18a, 18b of the items of protective equipment 16a, 16b.

[0032] The method in FIG. 3 shows that, in a first method step 100, a first operator-specific characteristic quantity is sensed by at least one first sensor unit 32a of the first item of protective equipment 16a. An operator-specific characteristic quantity is to be understood to mean a temperature, a moisture, an acceleration and/or a field strength. If a user 21 is wearing the eyewear, the user-specific characteristic quantity indicates, for example, a temperature, a moisture and/or capacitance of the skin of the operator, and therefore whether the eyewear is being worn correctly. The sensor unit 32 is realized as a temperature sensor, a moisture sensor, an acceleration sensor, a capacitive sensor or as a magnetic field sensor.

[0033] In a further method step 110, the first operator-specific characteristic quantity is converted into a sensor signal. In a further method step 120, the sensor signal is transmitted to the mobile functional unit 22. In the method step 130, enabling of an active operating state of the hand-held power tool 14a, 14b, 14c is effected by the mobile functional unit 22 in that an electrical energy supply for the hand-held power tool 14a, 14b, 14c is activated.

[0034] The method in FIG. 4 shows that, in a first method step 100, a first ID of a first protective equipment element 18a of a first item of protective equipment 16a is sent to a mobile functional unit 22. The mobile functional unit 22 receives the first ID of the first protective equipment element 18a of the first item of protective equipment 16a. In a second method step 110, a first operator-specific characteristic quantity is sensed by a first sensor unit 32a. In a third method step 120, from the first operator-specific characteristic quantity is converted into a sensor signal. In a further method step 130, the mobile functional unit 22 enables an active operating state of the hand-held power tool 14a, 14b, 14c, in that an electrical energy supply for the hand-held power tool 14a, 14b, 14c is activated.

[0035] An operator-specific characteristic quantity is to be understood to mean a temperature, a moisture, an acceleration and/or a capacitance. If a user 21 is wearing the eyewear, the user-specific characteristic quantity indicates, for example, a temperature, a moisture and/or capacitance of the skin of the operator, and therefore whether the eyewear is being worn correctly. The sensor unit 32 is realized as a temperature sensor, a moisture sensor, an acceleration sensor, a capacitive sensor or as a magnetic field sensor.

[0036] A list of all IDs of the protective equipment elements 18a, 18b of the items of protective equipment 16a, 16b are stored in a data storage unit 30 of the mobile functional unit 22.

[0037] It is also conceivable, however, that, in a further method, a mobile functional unit 22 receives the IDs of a plurality of protective equipment elements of a plurality of items of protective equipment, and enables an active operating state of the hand-held power tool 14a, 14b, 14c, in dependence on whether the item of protective equipment is worn, in that an electrical energy supply for the hand-held power tool 14a, 14b, 14c is activated.
