Abstract: The invention relates to a motor vehicle seat crossmember comprising: a tubular base body and receptacle section arranged on the base body for the torsion-free arrangement of a coupling element. In order to provide a motor vehicle seat cross-section that can be economically produced and that has a low weight and a high strength, it is provided that the receptacle section has a reinforcing tube that is arranged coaxial to the base body and lies on its inner or outer surface, and a cross-section deviating from a circle that is produced by joint deformation, especially cold formation, of the base body and the reinforcing tube.

Abstract: A constant resistance exercising apparatus and system comprising a series of resistance units, each comprising a storage drum, output drum, and a constant torque spring wound about each drum. Each resistance unit may be selectively actuated through a lever and clutch assembly that simply slides a gear arrangement in and out of contact with a respective output drum. Accordingly, through the effortless toggling of a lever, a user may select or deselect multiple resistance units to provide a desired quantitative and measurable level of constant resistive force. Exercise tools, including handgrips, leg cuffs, bars, and/or harnesses, may be connected to a cable extending from the resistance units, and thus, function as the interface between the exercising apparatus and the user.

Abstract: Provided is a weighted cable resistance apparatus, primarily for rehabilitation and therapy, and equally effective for recreational exercising. A frame with a perpendicularly attached seat form a rigid structure. The structure is supported on leveling screws or lockable casters for transport to bed-confined patients. Dead weights within the frame and the rigid seat structure stabilize the apparatus against overturning during use of the apparatus. At each end of the frame is attached a horizontally pivotable assembly, called a ‘module’. Each module contains weights which are, in turn, connected to a cable and to pulleys controlling the cable path. Vertically pivotable arms are mounted on the front of the is modules. The cables are guided to the end of the arms and past the exit pulleys, whereupon exercise tools can be connected. The twin module design provides simultaneous exercising with any two limbs.

Abstract: A guide bush for an adjustable length column for chairs, tables or the like is provided, in its inner portion, with a slide bush concentric of a central longitudinal axis for the guidance of a cylindrical housing of a gas spring. The outside wall of the slide bush is provided with spaced ribs for the reception and support, radial to the axis, in an upright tube of the column. The ribs are elastically deformable radially to the central longitudinal axis.

Abstract: An electronic component packaging system provides individual structural elements of modules that provide both the strength and the internal structure to mount electrical components such as circuit boards without the use of subracks. The resulting structure provides up to 15 percent more usable space for circuit boards. The modules are constructed as to be easily fixed to one another to form a multiple element modular packaging system.
