Seating furniture including a base fixed in position during use, a seat unit with a seat surface, and a leg unit moveable in relation to the seat unit and having a leg support surface. The leg unit is displaceable by a movement mechanism between a storage position and a use position. The movement mechanism transfers the leg unit from the storage position into the use position, and has an intermediate support displaceable in relation to the seat unit or the base by a pivoting guide. The pivoting guide has a first pivot lever between the intermediate support and the seat unit or the base, and the movement mechanism has a sliding guide with a sliding member guided in a translatory manner on the intermediate support, and the leg unit is attached to the sliding member.
摘要:
A fuel pump for delivering fuel has a housing part made from a coated material. An insert made from an electrically non-conductive material, such as for example phenolic resin, is pressed into the housing part. The insert which is produced from phenolic resin can be pressed into the housing part before a surface treatment of the housing part, since phenolic resin is not electrically conductive. As a result, the fuel pump can be produced particularly inexpensively.
