Abstract
Abstract A lift truck is shown to exemplify the invention in which a seat support member is pivoted at one side to allow the seat to be swung outwardly of one side of the truck from a forwardly facing operative position for operating the vehicle to a rearwardly facing non-operative position relative to a compartment housing the power source apparatus, such as an electric storage battery. A protective overhead guard device includes one pivotable and longitudinally adjustable connector and one longitudinally adjustable connector for adjusting the length of the guard for connection to a longitudinally adjustable and novel counterweight structure at different adjusted positions thereof, thereby enabling the same truck chassis to be utilized for a relatively wide range of lift truck capacities. In addition, the pivoted connector is adapted to provide an opening in the guard structure through which may pass a chain or cable of a lifting and transfer device which, with the pivoted seat structure, provides simple means for performing an efficient method of removing and replacing the power source or other devices without removing or disassembling the overhead guard or seat structure.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
126 words
An operator''s seat assembly for vehicles comprising mounting means connected to and extending transversely of the vehicle, operator''s seat means supported from said mounting means, and pivot means adjacent one end of said mounting means connecting said seat to said mounting means, said seat means being movable on said pivot means away from the opposite end of said mounting means to enable said seat means to be actuated from a forwardly facing operative position for operating the vehicle to a rearwardly facing non-operative position in which the seat means extends transversely outwardly of one side of the vehicle, said mounting means and seat means being pivotable about a transverse axis and pivoting forwardly about said axis when said seat means is located in said non-operative position.
Claim 2
Dependent Claim
126 words
An operator''s seat assembly for vehicles comprising mounting means connected to and extending transversely of the vehicle, operator''s seat means supported from said mounting means, and pivot means adjacent one end of said mounting means connecting said seat to said mounting means, said seat means being movable on said pivot means away from the opposite end of said mounting means to enable said seat means to be actuated from a forwardly facing operative position for operating the vehicle to a rearwardly facing non-operative position in which the seat means extends transversely outwardly of one side of the vehicle, said mounting means and seat means being pivotable about a transverse axis and pivoting forwardly about said axis when said seat means is located in said non-operative position.
Claim 3
Dependent Claim
61 words
An operator''s seat assembly as claimed in claim 1 wherein said mounting means includes bifurcated end portions adapted to receive in the spaces formed thereby a support portion of the seat means which comprises a member pivotable from the one bifurcated end to said operative and non-operative positions, said member being connectible to the opposite bifurcated end by detachable connecting means.
Claim 4
Dependent Claim
79 words
An operator''s seat assembly for vehicles as claimed in claim 1 wherein said seat assembly is mounted at the operator''s station of an industrial lift truck and which in said operative position extends rearwardly over prine mover or energy source compartment means to the lift truck and which in said non-operative position is remote from said compartment means such that prime mover or energy source means therein may be removed vertically outwardly thereof without interference by said seat means.
Claim 5
Dependent Claim
35 words
An operator''s seat assembly for vehicles as claimed in claim 1 wherein said pivot means is the sole pivot means enabling the seat means to be actuated from said operative position to said non-operative position.
Claim 6
Dependent Claim
24 words
An operator''s seat assembly for vehicles as claimed in claim 3 wherein the axis of said pivot means projects in a generally vertical direction.
Claim 7
Dependent Claim
51 words
An operator''s seat assembly for vehicles as claimed in claim 1 wherein said seat means in said operative position is located generally rearwardly of and in longitudinal alignment with said mounting means and wherein said seat means in said non-operative position is located generally forwardly and transversely of said mounting means.
Claim 8
Dependent Claim
35 words
An operator''s seat assembly for vehicles as claimed in claim 6 wherein said pivot means is the sole pivot means enabling the seat means to be actuated from said operative position to said non-operative position.
Claim 9
Dependent Claim
96 words
An operator''s seat assembly for vehicles as claimed in claim 6 wherein said seat assembly is mounted at the operator''s station of an industrial lift truck in which said operative position extends rearwardly over prime mover or energy source compartment means of the lift truck and which in said non-operative position is remote from said compartment means such that prime mover or energy source means therein may be removed vertically outwardly thereof without interference by said seat means, said pivot means enabling the seat means to be actuated from said operative position to said non-operative position.
Claim 10
Dependent Claim
45 words
An operator''s assembly for vehicles as claimed in claim 1, wherein said seat means includes a seat, a carrier plate beneath the seat and track means mounting the seat on the carrier plate for forward and rearward adjustment of the seat on the carrier plate.
Claim 11
Dependent Claim
56 words
An operator''s seat assembly for vehicles as claimed in claim 1 wherein spring means is provided for pivoting said mounting means and seat means forwardly about said axis when said seat means is located in said operative position, said spring means being ineffective for that purpose when said seat means is located in said non-operative position.
