Abstract: A seating unit that includes a linkage mechanism adapted to move the seating unit between closed, extended, reclined, and seat-lift positions is provided. The linkage mechanism includes a footrest assembly and a back-mounting link coupled to a seat-mounting plate, a base plate coupled to a lift-base assembly via a lift assembly, a drive bracket, a motor tube, and two linear actuators for automating adjustment of the linkage mechanism. In operation, a first phase involves a second linear actuator rotating the motor tube, thereby causing the seat-adjustment assembly to bias the seat-mounting plate. A second phase involves a first linear actuator rotating the drive bracket, thereby causing the footrest assembly to extend or retract without affecting the bias of the back-mounting link. A third phase involves the first linear actuator causing the lift assembly to raise and tilt the base plate directly over the lift-base assembly.

Abstract: which is rotatably supported in a housing part (16) of a housing via a roller bearing (22, 20) An axial spring element (32) is located between the roller bearing (22, 20) and a rotor component (34) installed non-rotatably on the rotor shaft (12). The axial spring element (32) includes an inner ring (40) and an outer ring (42), which are interconnected in an axially resilient manner, and the outer ring (42) is axially connected to the rotor component (34).

Abstract: Arching mechanism, for instance for backrests of seats, medical or orthopaedic apparatus or casings and the like, with a pressure element wherein at least one traction element connected with a tensioning mechanism engages, which, when the mechanism is actuated can produce bulging by preserving a relative elevation of apex of the convexity; the arching mechanism can comprise a frame with inserted pressure elements actuatable by adjusting device(s), whereby frame segments are length-variable pressure elements; traction elements provided with tensioning mechanism can engage a slitted, overlapping or bellows-like bulging body for the opening and closing of these areas, which produces a curving of the bulging body in a predetermined direction or directions.

Abstract: A longitudinally extending string of springs comprising a row of springs and a pair of fabric retainers securing the springs together. The row of springs may be a band of coil springs made of a single length of wire shaped to form a plurality of coil springs or multiple individual springs. The upper and lower end turns of the springs are located within pockets or receptacles created in the fabric retainers.
