Abstract: A vehicle seat drive system, in particular an airplane passenger seat drive system, not requiring special software. The systems will be adaptable to new conditions over the course of the life of the installation thereof. The systems is monitorable at any time, and is capable of automatically reporting the occurrence of system faults. To accomplish this a direct link to a network that can be connected to the internet is provided.

Abstract: A rotary pump with a plastic pump housing, that can be processed by injection molding, with a first housing part defining a pump space, which is connected to a second intermediate housing part accommodating an electric motor with a wound core stator. The rotary pump includes a plastic split core, the wound claw pole stator being mounted on the split core and a permanent magnetic rotor being mounted to rotate within the split core. A plastic motor housing part defines a motor space, wherein at least three axial and parallel split core ribs are provided between the split core and the claw pole stator, the ribs being distributed about the periphery of the split core at predetermined angles relative to each other. A return ring has first and second end sections, the return ring being connected to the wound claw pole stator, so that the first and second end sections are welded to each other. The stator is press-fit onto the split core via the ribs.

Abstract: The invention concerns a gear motor (1) with a fail-safe device (2) consisting of a housing (4), an electromotor (3), a reduction gear (5) with at least one planetary gear (6), an electromagnetic clutch (11) and an output gear shaft (13), wherein the planetary gear (6) has an internal gear. The internal gear is in mesh with at least one planetary wheel (8) and is fixed in its operation relative to the housing (4). The planetary gear comprises the electromagnetic clutch (11), a magnetically conductive armature and a magnetically conductive stator (21) in which an electromagnetic coil (15) is arranged. During the application of current to the electromagnetic coil (15) the internal gear (10) is secured against turning. The task of the invention is to provide for a reliable operation of the fail-safe device in a gear motor of such kind using less construction space and less number of components thus enabling simple assembly.
