- A-pillar front
- B-pillar intermediate piilar
- C-pillar rear pillar
- the invention exploits the existing window components by extending the sheet of transparent material (e g glass) to cover the pillar and integral window This allows the inclusion of the integral window without the need for additional components
- a plurality of windows can covered with a single piece of matenal
- the pillar (or pillars) having an integral window forms part of a ROPS
- at least two of said cab pillars comprise an tntegral window thereby increasing the visibility of the driver further still
- the cab may comprise a pair of front pillars, a pair of rear pillars and at least one intermediate cab pillar
- the intermediate pillars preferably comprise an integral window hi such a five- or six-pillar cab structure it is typically the B-p ⁇ lIar which presents the greatest obstruction to the driver's sight because it is located closest to the driver's head and, furthermore, often provides the ROPS
- the sheet of transparent material preferably extends from one of said rear cab pillars to the intermediate cab pillar and over the tntegral window
- the pillar is of a truss style construction having two parallel chords and a web therebetween
- the web may be formed from a plurality of connecting struts for example
- the pillar is of a Warren truss style construction and comprises a plurality of triangular integral windows formed within the web Not only is a Warren truss style construction aesthetically pleasing but it offers a particularly strong construction whilst maximizing the area of the integral window or windows
- FIG. 1 is a perspective view of a tractor in accordance with a first embodiment of the invention

- a tractor 10 comprises two front wheels 12 attached to respective ends of an axle 13 and rear wheels 14. Each of the wheels has an associated fender 16 for restricting the amount of mud and debris which can otherwise fly up from the wheel whilst the tractor is in motion.
- a driver (not shown) sits in the driver's seat 18 whilst the tractor 10 is in operation.
- a cab 20 comprises a roof 22 supported by a plurality of cab pillars. The cab 20 surrounds a driver's operating area and provides protection from the outside environment which will be discussed in more detail below.
- the cab comprises a pair of front cab pillars 24, often referred to as A-pillars.
- the A-piliars 24 are each disposed at a front corner of the driver's operating area, provide support for the cab roof 22 and provide part of a rigid frame in which a front windscreen is fitted.
- the cab further comprises a pair of rear cab pillars 26, often referred to as C-pillars. These are each disposed at a respective rear corner of the driver's operating area.
- the C-pillars 26 provide support for the rear corners of the cab roof 22 and provide part of rigid frame for a rear windscreen 27.
- the A-pillars 24 and C-ptHars 26 are formed from tubular steel which is bent into shape and welded during manufacture.
- the tops of the A-pillars 24 and C-pillars 26 are welded to a roof frame structure 28 which is also formed of tubular steel.
- the cab 20 further comprises a pair of intermediate pillars 30 which are each disposed forward of the C pillars 26 above the fender 16 of the rear wheel 14.
- Each intermediate pillar 30, often referred to as B-pillars is welded at its bottom end to a tower part of the driver's operating area and at its top part to the cab roof support structure 28.
- the B-pillars 30 provide extra support for the cab whilst also providing, together with the cab roof support structure 28, the ROPS which is a legislative requirement in most countries.
- the pillars can instead be bolted to the tractor frame at their lower end and may instead be formed from aluminium for example.
- each B-pillar 30 comprises a plurality of integral windows 32 within the line of sight of the driver.
- the windows 32 are provided by forming the B-pillar having a Warren truss style construction.
- this style of truss construction comprises angled struts 34 connecting a pair of parallel chords 36 The chords 36 and the struts 34 are welded together so as to leave triangular integral windows 32 aligned substantially transversely to the forward direction of the tractor 10
- the Warren truss-style construction provides a sufficiently strong support for the ROPS
- a single sheet of glass 40 extends from each respective C pi ⁇ lar 26 to the adjacent B-pillar and over the integral windows 32
- alternative transparent material may be employed instead of glass, such as plastic
- Each sheet 40 extends the full height of the pillars and forms a watertight seal with the cab roof 22 along the top and the fender 16 along the bottom
- the glass sheet 40 is alfixed to the respective pillars and horizontal frame work using known techniques such as a rubber, waterproof, seal (not shown)
- each B-piHar 30 provides a post upon which a cab door (not shown) can be hinged
- the invention delivers a significant increase in the visibility for the driver
- the field of vision represented by X of a driver (represented at 100) is significantly improved by the invention
- a traditional, completely opaque, B-pillar would completely block the field of view X located to the driver's immediate left and right sides
- the driver's vision over range X is at least significantly improved This is particularly advantageous from a safety perspective when driving on the public highway wherein the d ⁇ ver s blind spot is reduced in size if not completely eradicated
- a pillar in accordance with the invention can be formed with a truss style construction having an alternative web lay out without deviating from the scope of the invention That is to say that the struts 34 which connect the parallel chords 36 can alternatively be arranged leaving rectangular windows for example Alternatively further still, it is envisaged that a truss having a web of diagonal and horizontal struts can instead be employed In a very basic alternative to that described the pillar may comprise a single window wherein a truss style construction is not required.
- A-pillars 24 and/or C pillars 26 could instead, or additionally, comprise an integral window whilst remaining within the scope of the invention.
- a tractor having at least one pillar adjacent a d ⁇ ver's operating area.
- the pillar comprises and integral window within the lme of sight of the driver thereby improving the visibility thereof dunng the operation of the tractor.
- the integral window is covered by an extension of the window pane whteh covers a window defined between the associated pillar and an adjacent pillar, typically adjacent B- and C-pillars.
- a truss-style construction can be employed for the pillars wherein windows are provided in the gaps between the webbing.
