The table top, in plan view, is formed with first pair of opposite edges and a second pair of opposite edges. One edge of the first pair of edges is convex and the other edge of the first pair of edges is concave. The convex curvature and the concave curvature of the first pair of edges has a predetermined first radius of curvature of substantially equal size. One edge of the second pair of edges is longer than the other edge of the second pair of edges.

Abstract: An article of furniture, such as a chair, including a free-swinging seat and a free-swinging backrest. The chair includes a seat and backrest coupled to a chair frame, where the chair frame includes first and second laterally spaced apart components. The first and second components each have a floor strut and a pair of legs that may be arranged in a substantially triangular configuration for supporting the seat. The chair also includes a coupling device, which may include a spring element, coupled to the legs and configured to allow forward movement of the seat and backward movement of the backrest, where movement of the seat and backrest may occur independently of one another. In some embodiments, the maximum movement of the seat and backrest may be limited by restricting movement of the coupling device.

Abstract: A swivel joint for pivotably coupling a tray to a support element of a seating implement. The swivel joint includes a tubular inner structure arranged substantially coaxially with and non-rotatably connectable to the support element, and a mounting structure at least partially surrounding the tubular inner structure in a radial direction. The mounting portion is pivotable relative to the tubular inner structure and rigidly coupled to the tray. The tubular inner structure includes at least one opening extending in the peripheral direction between two angular positions, and the mounting structure has at least one projection which projects in a radial direction and engages with the at least one opening of the tubular inner structure. The swivel joint provides additional structural integrity to compensate for loads on the tray and also provides a pivoting point to allow the tray to move easily between positions of use and non-use.

Abstract: An item of seating furniture contains a seat providing a seat surface, a generally circular foot panel positioning the item of seating furniture on a floor, and a central part, which connects the seat to the foot panel and of which a vertical center axis runs centrally through the foot panel. The foot panel is of at least partially convex configuration and that side of the foot panel which is directed toward the floor is configured, at least in part, as a non-slip surface. This creates an ergonomic item of seating furniture which stands in a stable state.

Abstract: A method for monitoring motor vehicle systems that include mechanical components and at least one control device detects, in a first step, input signals and output signals as quantitative signals that characterize the operating behavior, assigns discrete qualitative values to value intervals of the input signals and output signals, which are established using a particular sequence of threshold values. A change to one of the qualitative values is recognized as an event, and consecutive events are stored as an event sequence. The event sequence is compared with a model of the normal behavior of the motor vehicle system, in particular a model composed of all event sequences of the proper operation of the motor vehicle system. If there is a match, it is assumed that the motor vehicle system is operating properly. If there is no match, erroneous operation is assumed.

Abstract: A seating implement has a base frame, a sitting surface, a back rest, and a tablet. The tablet is fastened to a support element provided on one side of the base frame by way of a linkage mechanism, so that the table can swivel between a substantially horizontal position of use and a position of non-use. The tablet is dimensioned to support a notebook computer and the support element has a section running in a substantially horizontal plane, on which the tablet is pivotally fastened by way of the linkage mechanism. The substantially horizontal section is oriented at an angle to the direction of the sitting surface, and the tablet can swivel about an axis substantially parallel to this section.

Abstract: An apparatus is proposed for detachable mechanical and electrical and/or optical connection of a recording appliance to an imaging apparatus. The apparatus comprises a mounting board and an insert board, which is pushed into the mounting board. In this case, the mounting board has guides on opposite sides, which hold the insert board in an interlocking manner in the pushed-in state. Electrical and/or optical contacts on the mounting board and on the insert board are connected to one another when the insert board has been pushed essentially completely into the guides on the mounting board. In one embodiment, a locking lever is provided, which converts a rotary movement of the locking lever to a linear movement of the insert board in the insertion direction. A latching position is provided in an end position of the locking lever.

Abstract: A supporting arm for a projection apparatus has first and second arm sections and an articulation apparatus therebetween for interconnecting the arm sections. The projection apparatus can be fastened on a free end of the second arm section. The articulation apparatus permits the second arm section to rotate relative to the first arm section between a first position, in which the longitudinal axes of the arm sections run substantially mutually parallel, and a second position, in which the longitudinal axes of the arm sections run substantially mutually at right angles. A spring apparatus is coupled to the arm sections and has a spring force selected to compensate for a weight force of the second arm section and of the projection apparatus fastened thereon over substantially an entire rotational excursion of the second arm section relative to the first arm section. A presentation apparatus having the supporting arm is also provided.

Abstract: A height positioning device for a presentation device contains a carrier to which a presentation element can be fastened, and a mount to which the carrier is attached and movable between first and second height positions. Also provided are a flexible traction mechanism having one end fastened to the carrier and a second end fastened to the mount or a stationary element, and a deflection element around which the traction mechanism is guided in the manner of a pulley. To hold the carrier at any desired position, the height positioning device contains a gas compression spring having a first end fastened to the deflection element and a second end supported on the mount, an element of fixed height, on the carrier or an element which can be moved with the carrier, such that the spring compensates for a weight of the carrier and the presentation element.
