Abstract
A compact work machine, such as a compact track loader and/or a compact utility loader, which can carry and operate a wide range of attachments while maintaining a reduced operating footprint.
Claims16
A seat system for a work machine, the seat system comprising:
- a seat frame;
- a seat supported on said seat frame;
- an armrest support supported on said seat frame;
- an armrest supported on said armrest support;
- a lap bar support supported on said armrest support;
- a lap bar pivotally connected to said armrest support via the lap bar support, wherein the lap bar is configured to pivot between a raised position and a lowered position;
- a display mounted on said lap bar and configured to display operational data of the work machine;
- and
- one or more control elements configured to be manipulated by a user to control functions of said work machine, wherein said one or more control elements includes a joystick;
- a joystick support supported on said armrest support, wherein said joystick is supported on said armrest support via said joystick support,
- wherein said lap bar support is positioned below said armrest, between said armrest and said joystick support.
8 more elements
A work machine comprising:
- a frame;
- a drive assembly supporting the frame and configured to propel the frame;
- an engine or motor mounted on said frame and configured to power the drive assembly;
- an operator cab mounted to said frame;
- a seat mounted in said operator cab;
- a seat frame supporting said seat;
- an armrest support supported on said seat frame;
- an armrest supported on said armrest support;
- a lap bar support supported on said armrest support;
- a lap bar pivotally connected to said armrest support via the lap bar support, wherein the lap bar is configured to pivot between a raised position and a lowered position;
- a display mounted on said lap bar, wherein said display is configured to display operational data of the engine or motor;
- and
- one or more control elements configured to be manipulated by a user to control functions of said work machine, wherein said one or more control elements includes a joystick;
- a joystick support supported on said armrest support, wherein said joystick is supported on said armrest support via said joystick support,
- wherein said lap bar support is positioned below said armrest, between said armrest and said joystick support.
12 more elements
A method of reducing unintended feedback loops during operation of a work machine, the method comprising:
- suspending a seat in a cab of the work machine, wherein said seat is supported on a seat frame;
- supporting an armrest support on said seat frame;
- supporting an armrest on said armrest support;
- supporting a lap bar support on said armrest support;
- pivotally mounting a lap bar to said armrest support via the lap bar support such that the lap bar is configured to pivot between a raised position and a lowered position;
- mounting a display to said lap bar;
- and
- mounting one or more control elements configured to be manipulated by a user to control functions of said work machine to said armrest support, thereby at least partially synchronizing movement of said seat and said one or more control elements and at least partially attenuating a transfer of energy from said cab to said seat to reduce the unintended feedback loops,
- wherein said one or more control elements includes a joystick, wherein the joystick is supported on said armrest support via a joystick support,
- wherein said lap bar support is positioned below said armrest, between said armrest and said joystick support.
