According to one aspect, an impeller comprises a hub and a plurality of blades extending from the hub. At least one blade includes a curved root portion proximal the hub, a curved tip portion disposed at an outer blade location, and a mid-portion intermediate the root portion and the tip portion. The mid-portion is substantially linear.

Impeller blade morphology

A coupling to attach a device such as an infant seat to an anchor member. One version of the coupling is characterized by a frame having a mouth with a seat configured to receive the anchor member and a lever movably mounted on the frame to hold the anchor member inside the mouth. The lever has a downwardly projecting finger that blocks the mouth of the notch in the closed position and allows access to the notch when moved to the open position. The coupling may include a stop member to resist movement from the closed to the open position. The coupling also may include a web adjuster or other connecting device operatively disposed between the coupling and the device.

Restraint coupling

A coupling and web adjuster to attach an infant seat to the passenger seat of a vehicle having a fixedly mounted rigid member to which the seat may be attached. The web adjuster has a cylindrical bar with a generally oval cross-section and a pair of ears mounted near each of its ends; a web that extends at least partially around the bar, a frame with a pair of channels in which the ears of the bar may slide, and one or more mechanical springs to normally push the bar toward the web stop and against the web. One version of the coupling is characterized by a frame having a notch on its distal end with a mouth/seat that is adapted to receive the fixedly mounted rigid member and a lever that is pivotally mounted inside the frame to hold the rigid member inside the mouth. The lever has a downwardly projecting finger that blocks the mouth of the notch when moved in one direction and allows access to the notch when moved in the other direction. Another version of the coupling is characterized by a rigid hollow cylinder with two notches in one end, a piston that slides back and forth inside the cylinder, a spring to push the piston toward the notches; and a means to prevent the piston from sliding out of the cylinder. Either coupling may then incorporate the first described web adjuster to attach the coupling to the child seat.
