A table system including at least one primary module and at least two secondary modules. The primary module includes a tabletop plate and a plurality of crossbars disposed parallel to each other and secured to the underside of the tabletop plate. A secondary module comprises a table leg having an upper end and a plurality of interlocking and bracing mechanisms disposed at the upper end of the table leg. A primary module and a secondary module together have an attached state and an interconnected state. The interlocking and bracing mechanisms have an open state and a closed state. In the attached state, each interlocking and bracing mechanism is in the open state, and is achieved by vertically setting the primary module onto the secondary module. In the interconnected state, each interlocking and bracing mechanism is in the closed state, interlocked independently into the interior portion of a crossbar.

Table system

The backrest of a chair comprises a frame, a backrest support and a neck support. A membrane is clipped into the frame, and the backrest support is articulated on a tilting mechanism. The frame comprises two side parts and two cross-pieces, the lower cross-piece lying at the height of the user's lumbar vertebra. The frame and the backrest support are interconnected in one piece. The component created as a result is advantageously a plastic injection molding produced by the gas injection technique (GIT) and the plastic is a glass-fiber-reinforced polyarylamide. This overall structure of the backrest provides a high level of sitting comfort by elastic support of the back in all major regions and directions of movement, but at the same time also considerably reduces production, transport and assembly complexity and has an aesthetically impressive, distinctive form.

Backrest

A movable table flap that which can be integrated into a work surface of a table, wherein in a closed position the upper side of the table flap is flush with the work surface of the table and a device for connecting various electric appliances and communication facilities is arranged underneath the table flap, wherein in the open position, the table flap can be both inclined and recessed simultaneously. The position of the table flap is changed by use of a compression spring, which is movable in an arched guide slot.

Moving table flap

A device for lumbar support for an office chair having a seatback including a seatback frame and a membrane stretched over the seatback frame. The device can be arranged behind the membrane and can be housed in the seatback frame to provide vertical and horizontal adjustment independent of the membrane. Preferably, the device includes a central part having two comparably rigid carrier elements connected to each other via an elastic element arranged therebetween, the rigid carrier elements each including a guide track that can be arranged in the seatback frame to provide the vertical adjustment. A front part includes a cushion attached to an upholstery plate, the upholstery plate facing the membrane. A rear part includes a plastic plate. The cushion and the plastic plate are connected via a clip connection, and the clip connection is guided in slots of the carrier elements.
