Abstract: A battery pack for supplying electrical components, in particular heating elements, includes a battery unit which has at least one battery received in a first housing part and a control unit for controlling a voltage to be output or a current to be output, the control unit having an electronic part received in a second housing part. According to the invention, the first and second housing parts are connected together detachably in a retaining position prescribed by a limit stop, contacts disposed on the first housing part in the retaining position having a conductive connection to contacts disposed on the second housing part.

Abstract: The invention relates to a shoe having an electrical device integrated in the shoe, an operating part for manual control of the device by means of at least one operating element of the operating part, an electrical contact element which is connected to the device via an electrical conductor, a housing for the electrical contact element, a housing part of the housing which is connected securely to the shoe having a recess for receiving the contact element in the recess, the housing having a closing element which is connected securely to the housing part and covers the recess in a closed position of the closing element, the closing element having a first connection element and the housing part having a second connection element which can be connected detachably to the first connection element for fixing the closing element in the closed position.

Abstract: An article of clothing, comprising an operating part for manually operating a controllable device which can be connected to the article of clothing by means of at least one operating element of the operating part, wherein the operating part comprises a first molding, which is rigidly connected to the article of clothing and which comprises the at least one operating element, and a second molding, which comprises a holder for a control unit of the device and can be connected to the first molding, wherein the first molding comprises at least one first retaining element and the second molding comprises at least one second retaining element, wherein the two retaining elements can be brought in mutual engagement with each other so as to establish a detachable connection between the first molding and the second molding.

Abstract: The invention relates to an electrically heatable sock having a foot part and a leg part abutting thereon, at least one heating element being disposed on the foot part which is connected via supply lines to terminals for a voltage supply which has a battery, the terminals being disposed in the upper region of the leg part. As a result of the fact that a cuff which can be folded over is disposed on the upper end of the leg part, the terminals being attached and formed on the side of the cuff situated inside in the folded-over state in order to fix the battery in the correct position in the folded-over state of the cuff and to retain it at least partially, a sock is made possible which is simple to produce and comfortable to wear and ensures a reliable attachment of the components necessary for heating.

Abstract: The invention relates to an electrically heatable sheet of glass (10), including at least one electrically conductive coating applied on at least one side of the sheet of glass and also to at least one contacting applied at least in regions on the coating, the contacting being configured as a spray coating.
