摘要:
In an adjusting device for a seat in a motor vehicle, a sliding seat guiding mechanism moves the seat in a generally horizontal direction. The guide mechanism includes an upper part secured to the seat and a support member secured to the floor of the vehicle. A rack is attached to the upper part and is driven by a pinion mounted on the support member for moving the seat in the generally horizontal direction. The rack is adjustably mounted on the upper part to permit limited movement of the rack in the generally vertical direction disposed transversely of the generally horizontal direction of movement of the seat so that proper engagement of the rack and the pinion is assured.

Adjusting mechanism for a seat, particularly a seat of an automotive vehicle, in which the seat rests on carriers elongated in the direction of shifting movement, seat shifting guides being interposed, and the carriers being equipped with integrally connected, upwardly directed lugs which laterally back the seat shifting guides.
摘要:
A mounting arrangement for a vehicle seat assembly including an electrically operated seat adjusting device which permits expedient fastening of the seat assembly to a vehicle floor and which essentially consists of lockable engaging connections provided on at least one side of the seat adjusting device as the fastening mechanism between the seat adjusting device and the vehicle floor and/or between a seat shell of the seat assembly and the seat adjusting device. On the opposite side of the seat adjusting device there are provided fastening connections preferably formed as screw connections which may be tightened to lock said engaging connections for a firm fastening of the assembly. The seat adjusting device is adapted to be manually operated by an auxiliary actuating device in the event of malfunction of elements thereof such as drive motors, gear units or interconnecting flexible shafts.

摘要:
A seat adjustment mechanism especially suited for motor vehicle seats is composed of at least one motor mechanism for adjustably moving a seat member through a drive connection having at least two mutually engaging force transmission parts. In order to avoid rattling of the adjustment mechanism when adjusting movement of the seat is to be effected in a direction where the adjusting movement is abetted by the weight of the seat member itself, a braking device is provided which counteracts the adjusting force of the motor mechanism applied in that direction.

An imaging system includes positron emission tomography (PET) detectors (30) shrouded by broadband galvanic isolation (99) and coincidence detection electronics (50, 50ob), or other radiation detectors. A magnetic resonance scanner includes a main magnet (12, 14) and magnetic field gradient assembly (20, 20′, 22, 24) configured to acquire imaging data from a magnetic resonance examination region at least partially overlapping the examination region surrounded by the PET detectors. A radio frequency coil (80, 100) has plurality of conductors (66, 166) and a radio frequency screen (88, 188, 188EB, 188F) substantially surrounding the conductors to shield the coil at the magnetic resonance frequency. The radiation detectors are outside of the radio frequency screen. Magnetic resonance-compatible radiation collimators or shielding (60, 62) containing an electrically non-conductive and non-ferromagnetic heavy atom oxide material are disposed with the radiation detectors.

In a combined system, a magnetic resonance (MR) scanner includes a magnet (10, 110) configured to generate a static magnetic field (B0) at least in a MR examination region (12) from which MR data are acquired. Radiation detectors (40, 41, 140) are configured to detect gamma rays generated by positron-electron annihilation events in a positron emission tomography (PET) examination region (70). The radiation 5 detectors include electron multiplier elements (60, 160) having a direction of electron acceleration (ae) arranged substantially parallel or anti-parallel with the static magnetic field (B0). In some embodiments, the magnet is an open magnet having first and second spaced apart magnet pole pieces (14, 15) disposed on opposite sides of a magnetic 10 resonance examination region, and the radiation detectors include first and second arrays (40, 41) of radiation detectors disposed with the first and second spaced apart magnet pole pieces.

A generally cylindrical set of coil windings (10, 30, 80) includes primary coil windings (12, 32, 82) and shield coil windings (14, 34, 84) at a larger radial position than the primary coil windings, and an arcuate or annular central gap (16, 36, 86) that is free of coil windings, has an axial extent (W) of at least ten centimeters, and spans at least a 180° angular interval. Connecting conductors (24, 44, 94) disposed at each edge of the central gap electrically connect selected primary and secondary coil windings. In a scanner setting, a main magnet (62, 64) is disposed outside of the generally cylindrical set of coil windings. In a hybrid scanner setting, an annular ring of positron emission tomography (PET) detectors (66) is disposed in the central gap of the generally cylindrical set of coil windings.
