First Claim
1. In an over the highway vehicle having a body defining an occupant space and an access opening to the space, an improved door construction comprising:
- a) a door pivotally connected to the body and having pivotally connected upper and lower positions;
b) the door being pivotal relative to the body between a closed position and a full open position allowing unobstructed passage into and out of the space;
c) the lower portion being pivotal relative to the upper portion between an aligned condition for closing the opening and an articulated condition wherein the portions are generally juxtaposed;
d) the portions being in a generally vertically aligned relationship when in the aligned condition and in a generally side by side relationship, when in the articulated condition;
e) a tether interposed between the body and the lower portion; and
, the tether limiting pivotal movement of the door when the lower portion is in the aligned condition to a partially open position and permitting movement of the door to the full open position when the lower portion is in the articulated condition.

Abstract
An over the highway vehicle having a body defining an occupant space and an access opening to the space is provided. A passenger access door is pivotally connected to the body. The door has pivotally connected upper and lower sections and is pivotal relative to the body between a closed position and partial and full open positions allowing unobstructed passage into and out of the space. The lower section is pivotal relative to the upper section between an aligned condition for closing the opening and a condition wherein the panels are generally juxtaposed. A tether is interposed between the cab and the lower section for limiting pivotal movement of the door when the door is in its aligned condition to the partially open position and permitting movement of the door to the full open position when the door is in the juxtaposed condition.

5. An over the highway service vehicle comprising:
-
a) a cab defining a compartment for an operator and at least one passenger, the compartment having an access opening;
b) a door having upper and lower sections and a hinge interconnecting the sections;
c) the door being pivotally connected to the cab for selectively closing the opening;
d) the door being pivotal relative to the cab to closed, partially open and full open positions;
e) the door sections being shiftable between aligned and substantially juxtaposed conditions;
f) a tether connected to the cab and the lower section and sized to limit door shifting between the closed and partially open positions when the sections are in the aligned condition; and
g) the tether being sized and positioned to permit the door to be shifted to the full open position when the sections are in the substantially juxtaposed condition. - View Dependent Claims (6, 7, 8, 9)

10. A door for a service vehicle, the door comprising:
-
a) an upper section including a window opening;
b) a lower section pivotally connected to the upper section and moveable between a section aligned condition for door closure and a section juxtaposed condition for use when the door is in a full open position;
c) latching for securing the sections together when the sections are in the juxtaposed condition and securing the door to the vehicle when the section are in the juxtaposed condition;
d) a tether connected to the lower section and connectable to the vehicle for limiting door opening to partial opening when the sections are in the aligned condition and permitting full open when the sections are in the juxtaposed condition. - View Dependent Claims (11)

12. A process of controlling the extent of opening of an articulated access door to an occupant space in a cab of a service vehicle comprising:
-
a) opening the door while limiting the opening of the door when upper and lower sections of the door are vertically aligned by extending a tether between one anchor secured to the lower section and another anchor secured to the cab at an elevation above an axis of section articulation;
b) pivoting the lower section about the axis to juxtapose the sections and bring the one anchor above the axis thereby extending the effective horizontal length of the tether; and
,c) while the sections are juxtaposed moving the door to a full open position. - View Dependent Claims (13)
