Seat and control lever interlock
First Claim
1. In a lift truck having a power source compartment, an operator seat mounted forwardly of the compartment for forward pivotal movement from a normal position in which the seat extends over a portion of the compartment and operator control lever means adjacent the seat mounted for forward pivotal movement from a normal position in which the control lever means extends over a portion of the compartment, interlocking linkage means operatively connected between the seat and control lever means responsive to forward pivotal movement of said seat for maintaining said control lever means in a forwardly pivoted inoperative position following movement of the control lever means to said forwardly pivoted position, said seat being mounted pivotally from a transverse pivot shaft and said linkage means being operatively connected between said shaft and said control lever means, whereby forward pivotal movement of said seat rotates said shaft to cause actuation of said linkage means.

Abstract
A seat and hydraulic control lever interlock for lift trucks in which access to a battery compartment is in part enabled by pivoting the operator seat forwardly over the steering wheel, which pivotal movement causes interlocking lever means between the seat pivot and hydraulic control levers to actuate to an armed position. Forward pivotal movement of the control levers to an inoperative position to clear the battery compartment allows the lever means to move to a position in which the control levers are held in such inoperative position until the seat is pivoted rearwardly over the battery compartment.
