F16H037/06

US Classification:

74661, 74425, 318 15

Abstract:

An electro-mechanical actuator including a plurality of motors for driving an output shaft. The actuator may be incorporated into a window lift mechanism, such as a mechanism including a dual rack and pinion assembly. According to another aspect of the invention there is provided a variety of anti-back-drive mechanisms, e. g. clutches. A clutch according to one embodiment includes locking pawls that resist back-drive. In another embodiment, locking cams rotate relative to a carrier to resist back-drive. An actuator consistent with the invention may incorporate an impact mechanism including a flexible carrier. The carrier flexes to prevent impact forces at an output gear train from coupling to an input gear train.

Abstract:

An electro-mechanical actuator for a window lift mechanism including a plurality of motors for driving an output shaft. The actuator may be incorporated into a window lift mechanism including a dual rack and pinion assembly, for driving the pinions along the racks. According to another aspect of the invention there is provided a variety of anti-back-drive mechanisms, e. g. clutches. A clutch according to one embodiment includes locking pawls that resist back-drive. In another embodiment, locking cams rotate relative to a carrier to resist back-drive.

Inventors:

Macram N. Bishai - Weston MA

Assignee:

McCord Winn Textron - Winchester MA

International Classification:

B60N 202

US Classification:

297339

Abstract:

An adjustable automotive vehicle seat is equipped with a height adjust mechanism that includes a U-shaped frame having laterally spaced side members and a round front cross member that is mounted on the front ends of the side members for rotation about its centerline. A plurality of bow shaped leaf springs are spaced across the width of the seat with their front ends secured to the round front cross member. The rear ends of the leaf springs are secured to a slidable rear cross member. An electrically powered, reversible ball screw actuator translates the rear cross member in the longitudinal direction so that the height of the seat is adjusted by adjusting the curvature of the bow shaped leaf springs.

International Classification:

F02M 2300

US Classification:

123533

Abstract:

An air fuel injection system for an internal combustion engine includes a plurality of fuel injectors supplied with fuel from a common fuel supply and supplied with air for producing a fuel spray pattern immediately upstream of an inlet valve to the combustion bowl of one of the engines cylinders and downstream of the induction air passage which supplies combustion air to the combustion bowl. The injection air supply is provided by an integral motor pump assembly having an electric motor driving a balanced lobe vane pump. The pump motor is electrically driven to charge the fuel injectors with high pressure air before the engine is started and independent of engine operation. The balanced lobe vane pump has an inlet connected to the PVC valve of the engine to provide a oil mist lubrication of the operative wear surfaces of the vane pump and the vane pump has an inlet connected to an air manifold for supplying lower noise and pulse air pressure thereto.

International Classification:

A97C 746

US Classification:

297284

Abstract:

A high pressure pumping system for power inflating and power bleeding the lumbar support of a vehicular seat including a high pressure air cell mounted in the back support. A two-position pneumatic switch serves to selectively alternately reverse a motor and pump to inflate the air cell to a predetermined capacity 5 or greater p. s. i. , and to manually deflate the air cell through a bleed valve until the system pressure is lower than the set pressure of a pressure cut-off switch whereupon the motor and pump power bleed the system.

US Classification:

2972846

Abstract:

A low pressure pumping system for power inflating and power bleeding the lumbar support of a vehicular seat including a low pressure air cell mounted in the back support. A two-position pneumatic switch serves to selectively alternately reverse a motor and pump to inflate the air cell to a predetermined capacity of less than 5 p. s. i. , and to deflate the air cell through a bleed valve. The two-position pneumatic switch includes a double pole, double throw switch and a slide valve which is positioned open when the air cell is inflated. The motor is sized to stall when the predetermined capacity is attained to prevent over inflation of the air cell.

International Classification:

F04C 18344
F04C 2700

US Classification:

418 14

Abstract:

A high pressure vane pump has a two-piece rotor enclosed by a housing having an inlet and an outlet and an eccentric ring for controlling the reciprocation of vanes in a guide part of the rotor; the eccentric ring is closed by opposite end plates and a moveable crown part of the rotor is supported on the guide part to provide four degrees of freedom between the guide part and the crown part including movement of the crown part axially of the guide part; movement of the crown part clockwise and counterclockwise of the guide part; and yaw movement of the crown part with respect to the vertical axis of the guide part. Rotation of the rotor causes the crown part to be shifted axially of the guide part to increase the pressure output of the pump at high speed operation and to reduce the frictional losses between the rotor and the housing during start-up.
