Sliding support mechanism with improved reliability and serviceability

摘要

Motorized rack-and-pinion sliding support mechanisms are disclosed. One or more shafts are coupled to pinions configured to engage with one or more racks and configured to be driven by one or more motors. The shaft(s) are configured to be manually disengageable from the motor(s), allowing the mechanism to slide freely in the event of a motor failure. The mechanism is further configured to reduce premature component wear leading to poor gear mesh caused to by forces on the mechanism during use.
