Abstract: A chair has a seat with a seat shell. A frame for supporting the seat has, on its side facing the seat, a mounting strut running parallel to the plane of the seat shell. An underside of the seat shell if formed with a receiving profile for the mounting strut. The receiving profile has a fastening section extending from a circumferential edge of the seat shell parallel to a plane of the seat shell into the interior of the seat shell and having an access opening at the circumferential edge of the seat shell. A clamping strip is provided for clamping the mounting strut in the fastening section. The clamping strip is slid from the access opening in a direction parallel to a longitudinal direction of the fastening section and is fixed in its end position in the fastening section perpendicular to the plane of the seat shell.

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: 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 producing a combustion chamber, particularly for airbags, with a barrel shaped body to which an ignition chamber is attached by welding and which has a transition opening between the ignition chamber and the barrel shaped body and a discharge opening in the barrel shaped body lying substantially opposite the transition opening, the barrel shaped body having a wall thickness in the vicinity of the discharge opening and in the vicinity of the transition opening or of the region where the ignition chamber is attached is greater than the wall thickness of the remainder of the barrel shaped body.

Abstract: A rotor (2) and/or rotor housing (1) for a camshaft adjuster for a motor vehicle engine and a method for manufacturing the same.

Abstract: A shiftable ink knife holder supports a plurality of spaced ink knives in an elongated support. The support is rotatable about an axis of rotation between working and rest positions. The rotation of the support can be accomplished by suitable drive motors. These drive motors also engage and disengage locking bolts that, in their locked position, engage the support.

Abstract: An electric control arrangement for controlling the speed of a roll driving motor for rolling mills for manufacturing hollow blocks is described. A power controller determines from the speed, field strength and armature current of the driving motor, the actual value of the motor power, compares the latter with a reference value, and generates a controlled variable which is fed to a current controller of the control arrangement to control the motor so that the motor delivers constant power.
