1. A vehicle door handle, comprising
first and second levers mounted so that they can rotate on a common support, the levers not being coaxial and being arranged so that the first lever operates the second lever which operates a mechanical link that operates the lock.
2. The handle as claimed in claim 1, arranged so that the first lever is in contact with the second lever.
3. The handle as claimed in claim 1, further comprising a cooperation ramp via which the first lever operates the second lever.
4. The handle as claimed in claim 3, in which the first lever carries the cooperation ramp.
5. The handle as claimed in claim 1, arranged so that rotation of the first lever over a first angle \u03b81 causes rotation of the second lever over a second angle \u03b82 greater than the first angle.
6. The handle as claimed in claim 1, arranged so that there exists at least one configuration of the handle in which a rotation axis of the second lever lies between a rotation axis of the first lever and the ramp.
7. The handle as claimed in claim 1, further comprising a manual operating member arranged to operate the first lever directly.
8. The handle as claimed in claim 7, further comprising an operating ramp via which the member operates the first lever.
9. The handle as claimed in claim 8, wherein the member carries the operating ramp.
10. The handle as claimed in claim 1 further comprising a sheath receiving the cable and having an upstream end rigidly fixed to the support.
The claims below are in addition to those above.

I claim:
1. A compound planetary gear box for a wind turbine having a turbine blade and an electrical power generator for converting low-speed, high-torque rotary power from the turbine blade to high-speed, low-torque rotary power for electrical power generation, the gear box comprising:
a housing;
a ring gear substantially fixed relative to said housing at the interior thereof;
a planet carrier mounted for rotation about a generally central axis within said ring gear and adapted to be driven at a first end thereof by a turbine blade;
a removable end cover detachably secured to said housing adjacent a second end of said planet carrier;
a plurality of planet pinions at spaced locations on said planet carrier around said central axis, with the axes of said planet pinions extending generally parallel to said central axis of said planet carrier;
first and second bearings for each said planet pinion at first and second ends, respectively, of said planet pinion for engaging and supporting said ends of said planet pinion for rotation relative to said planet carrier;
a plurality of gear teeth on each said planet pinion engageable with said ring gear and located between said first and second bearings;
a planet gear on each said planet pinion located between said first and second bearings;
a sun gear rotatable about said central axis and engageable by said planet gears; and
a final stage gear driven by, and detachably mounted to, said sun gear adjacent said second end of the planet carrier;
whereby all of the rotary power from the turbine blade is transmitted through said planet pinions, with each pinion being supported for rotation by bearings at both ends thereof.
2. The gear box of claim 1, wherein each said planet pinion is of generally the same outer diameter at said first and second ends thereof.
3. The gear box of claim 2, wherein said bearings for each said planet pinion are of the same type and generally of the same size.
4. The gear box of claim 3, wherein the outer diameter of each said bearing is generally twice said outer diameter of said ends of said planet pinion.
5. The gear box of claim 2, wherein said bearings for each said planet pinion are of generally the same width and inner and outer diameters.
6. The gear box of claim 1, wherein said first bearing for said first end of each said planet pinion is engaged and supported by said planet carrier, further comprising at least one bearing support for engaging and supporting said second bearings for said second ends of said planet pinions relative to said planet carrier.
7. The gear box of claim 6, wherein said at least one bearing support comprises an end plate detachably secured to said second end of said planet carrier.
8. The gear box of claim 6, wherein, with said final stage gear removed from said housing, said at least one bearing support is detachable.
9. The gear box of claim 8, wherein, with said at least one bearing support removed, said second bearing at said second end of each said planet pinion is accessible for removal.
10. The gear box of claim 9, wherein, with said second bearings at said second ends of said planet pinions removed, said planet pinions are accessible for removal.
11. The gear box of claim 10, wherein, with said planet pinions removed, said first bearings at said first ends of said planet pinions are accessible.
12. The gear box of claim 1, wherein said gear teeth on said planet pinions are helical and said planet gears have helical gear teeth, with the inclination of said gear teeth on said planet gears being generally equal, but opposite, to the inclination of said gear teeth on said planet pinions.
13. The gear box of claim 1, wherein said planet pinions and said planet gears are spur gears.
14. The gear box of claim 1, further comprising an output pinion engageable with said final stage gear, with the axis of said output pinion extending generally parallel to but spaced apart from said central axis of said planet carrier.
