Abstract: A support having two extensions which protrude forward on both sides in the final lower region, and an identical shoulder rest form a monolithic plastic hard shell. Vertically adjustable strips that support a waist belt are fixed to the extensions while a should mounting adjoins the shoulder rest via a ball-and-socket joint. The should mounting supports shoulder belt arrangements encompassing one respective top belt and a bottom belt which is joined to the top belt via a buckle, is pulled all the way to the extension through the buckle, and is anchored there. A bag for carrying material that is to be transported is disposed on the front face of the support, in the hard shell, the bag being accessible from the front, while straps for fastening a snowboard, showshoes, a helmet, or other large objects are mounted on the rear face thereof.

Abstract: An electric power tool (10) has at least one battery-powered electric motor, and the electric motor and the battery can be placed on the back of a user by means of a wearable unit (50). Via a flexible shaft (30), a driven tool (40) is driven by the electric motor. The wearable unit (50) has guide means (63 through 65), which engage the flexible shaft (30) in such a way that beginning at the back region of the user (52), this shaft is fixed in the shoulder region in such a way that it is secured against slipping off. This assures good guidance of the flexible shaft (30) and enables the user (52) to work ergonomically (FIG. 1).
