Drive for adjustable parts bear against or beds

摘要

The invention relates to a drive for adjustable parts of recliners or beds, comprising a multi-part housing, at least partly sealed off against the outside, in which electrical drive components, such as an electric motor, and mechanical drive components, such as a linkage, are located, where at least all the electrical drive components are located in the sealed section of the housing and in which the mechanically movable components leading out of the sealed housing section are sealed off against the wall of the housing section by means of a seal. The purpose of the invention is to create a drive for adjustable parts of recliners or beds which offers sufficient safety when used in damp or wet environments. The invention is characterized in that the seal (19) is of one-piece design and includes a first sealing element (20) for sealing the housing, and a second sealing element (21) for sealing the feed-through (18), where the first sealing element (20) is designed as a toroidal sealing ring and the two sealing elements (20; 21) essentially lie in one plane when not assembled, and that the second sealing element (21) can be rotated in relation to this plane.
