Abstract
An electrical connecting device for an air bag of a motor vehicle is disclosed. An inner cylinder is secured to a steering wheel, and an outer cylinder is secured to a steering column for the steering wheel. A flexible helical stirp is disposed between the inner and outer cylinder. A sun gear is formed on an outer periphery of the inner cylinder, a ring gear is formed on a side of the outer cylinder, and planet pinion is engaged with the sun gear and the ring gear. A stopper is provided for stopping the planet pinion at revolution ends thereof, and a mark provided at a neutral position diametrically opposite to the stopper.
Claims6
An electrical connecting device for a steering wheel of a motor vehicle comprising:
- an inner cylinder secured to the steering wheel;
- an outer cylinder secured to a steering column for the steering wheel;
- a flexible helical strip disposed between the inner and outer cylinders, said strip having one end connected to the inner cylinder and an opposite end connected to the outer cylinder;
- a planetary gear device having a sun gear formed on an outer periphery of the inner cylinder, a ring gear formed on an inner periphery of the outer cylinder, and a planet pinion engaged with the sun gear and the ring gear;
- and
- a stopper provided on a periphery of the ring gear for stopping a planet pinion at revolution ends thereof;
- and
- said inner and outer cylinders being formed with shelves adjacent a bottom of said sun gear and said ring gear;
- and
- said planet pinion being supported by teeth of said planet meshing with said sun and ring gears resting on said shelves.
