| Abstract: |
An articulated wheel chair includes front and rear sections which are pivotally connected together to permit pivoting therebetween about a vertical axis. The front section is provided with a pair of support wheels and the rear section is provided with a pair of propulsion wheels driven by an electric motor. A seat for the occupant is pivotally mounted on the rear section and is connected to the front section by a link to cause pivoting of the seat in response to articulated pivoting movement between the sections.

What is claimed is:
1. An articulated wheel chair comprising:
- a front section having a pair of support wheels journaled thereon for support thereof,
- a rear section having a pair of propulsion wheels connected thereto for support thereof,
- means pivotally connecting said front and rear sections together for pivotal movement therebetween about an articulating vertical axis,
- power means on said rear section drivably connected to said propulsion wheels for driving the latter,
- a seat pivotally mounted on said rear section for pivotal movement relative thereto,
- a generally vertically disposed elongate steering rod on said front section and being rotatable about its longitudinal axis, means interconnecting said steering rod with said rear section to produce articulated pivotal movement between the sections in response to rotation of said steering rod,
- and motion transmitting means interconnecting said front section with said seat for causing pivoting of the seat in response to articulated pivoting movement between the sections.
