Abstract

A door and an integrated safety net system for a recreational vehicle having a chassis with a step-through door opening. The door includes a forward end and a rearward end, and a hinge coupled between the rearward end of the door and the chassis of the vehicle. A door panel or upper and lower safety nets are coupled to the door frame forward of the hinge and coupled to the chassis of the vehicle on or rearward of the rearward side of the door opening. The safety net and the door are collectively and cooperatively movable as the rear-hinged door moves to the open position or closed position. The door includes a latch at the forward end of the door to provide one operational step to release or secure the door and the integrated safety nets to the chassis upon ingress or egress of the vehicle.

Claims

1. A door for a recreational off-highway vehicle having a chassis with a step-through door opening, the vehicle being configured to carry occupants on seats in a side-by-side configuration, the seats having upwardly facing lower seat support surfaces and seat backs, the seat backs having a shoulder region approximately 17 inches above the upwardly facing surface of the lower seat support surfaces, the door comprising:

a forward end and a rearward end;

a hinge secured directly to the chassis of the vehicle and positioned between the rearward end of the door and a rearward side of the step-through door opening of the chassis of the vehicle, wherein the hinge has a pivot axis that slopes rearwardly such that the door is held open by gravity;

a shoulder retention portion slightly forward of and laterally outboard of the shoulder region of the seat back;

a forward portion extending forwardly and downwardly from the shoulder retention portion to a vertical height below the shoulder region of the seat back.

2. The door of claim 1, further comprising an upper frame member extending along an upper perimeter of the door, from above the shoulder region to the forward end of the door.

3. The door of claim 2, further comprising a mid-frame member extending below the upper frame member, the mid-frame member securing an interior handle for the occupant.

4. The door of claim 2, further comprising a mid-frame member and a door panel, the mid-frame member extending below the upper frame member, the mid-frame member and the upper frame member securing the door panel.

5. The door of claim 2, wherein a door panel extends from the upper frame member to a lower perimeter of the step-through door opening.

6. The door of claim 2, wherein the upper frame member extends forwardly and downwardly from the shoulder region to a door mid-region, in the door mid-region the upper frame member angles to a lesser slope as it extends forward to the forward end of the door.

7. The door of claim 1, wherein when an occupant is sitting in one of the seats, the shoulder retention portion of the door is adjacent to the occupants'"'"' outboard shoulder and is approximately 6 inches forward of the seat back and at least 17 inches above the upwardly facing lower seat support surface such that the shoulder retention portion provides passive retention of the occupant'"'"'s outboard shoulder.

8. The door of claim 7, wherein the shoulder retention portion of the door is approximately 19 inches from the upwardly facing lower seat support surface.

9. The door of claim 1, wherein when an occupant is sitting in one of the seats, a highest part of the door is adjacent to the occupant'"'"'s head to enable visibility of terrain forward of the vehicle.

10. The door of claim 1, wherein the rearward end is at a height that is lower than another height of a highest part of the door.

11. The door of claim 1, further comprising a latch at the forward end and the hinge is at the rearward end, such that the door opens rearwardly.

12. The door of claim 1, wherein the pivot axis is longitudinally rearward of a forward face of the seat back along an axis tilted in approximately the same direction as the seat back forward face.

13. The door of claim 1, wherein when an occupant is sitting in one of the seats and the door is closed, the shoulder retention portion is adjacent to the occupant'"'"'s outboard shoulder and provides passive retention of the occupant'"'"'s outboard shoulder.

14. A door for a recreational off-highway vehicle having a chassis with a step-through door opening having a rearward side and a forward side, the vehicle being configured to carry occupants on seats in a side-by-side configuration, the seats having upwardly facing lower seat support surfaces and seat backs, the seat backs having a shoulder region approximately 17 inches above the upwardly facing surface of the lower seat support surfaces, the door comprising:

a forward end and a rearward end;

a hinge secured directly to the chassis of the vehicle and positioned between the rearward end of the door and a rearward side of the step-through door opening of the chassis of the vehicle at the rearward side of the door opening, wherein the hinge has a pivot axis that slopes rearwardly such that the door is held open by gravity;

a shoulder retention portion slightly forward of and laterally outboard of the shoulder region of the seat back;

a forward portion extending forwardly and downwardly from the shoulder retention portion to a vertical height below the shoulder region of the seat back;

a latch at the forward end of the door that engages a receiver at the forward side of the door opening;

an upper frame member extending along a top of the door from the forward end to the rearward end.

15. The door of claim 14, further comprising a door panel secured to the upper frame member.

16. The door of claim 14, wherein the upper frame member extends downwardly from the shoulder retention portion to a door mid-portion.

17. The door of claim 14, wherein when an occupant is sitting in one of the seats and the door is closed, the shoulder retention portion is adjacent to the occupant'"'"'s outboard shoulder and provides passive retention of occupant'"'"'s outboard shoulder.

18. A door for a recreational off-highway vehicle having a chassis with a step-through door opening, the vehicle being configured to carry at least one occupant on at least one seat, the at least one seat having upwardly facing lower seat support surfaces and a seat back, the seat back having a shoulder region above the upwardly facing surface of the lower seat support surfaces, the door comprising:

a forward end and a rearward end;

an upper safety frame that includes an upper safety net and a first rotational axis;

a lower safety frame that includes a lower safety net and a second rotational axis;

a hinge that includes a third rotational axis and couples the door to the chassis of the vehicle, wherein the first rotational axis, the second rotational axis, and the third rotational axis are substantially fixed relative to each other as the door and the safety frames cooperatively rotate to an open and a closed position;

a shoulder retention portion laterally outboard of the shoulder region of the at least one seatback and when the at least one occupant is sitting in the at least one seat, the shoulder retention portion is adjacent to the at least one occupant'"'"'s outboard shoulder such that the shoulder retention portion provides retention of the at least one occupant'"'"'s outboard shoulder; and

a forward portion extending forwardly and downwardly from the shoulder retention portion to a vertical height below the shoulder region of the seat back enabling visibility of the ground.

19. The door of claim 18, wherein the shoulder retention portion provides passive retention of the at least one occupant'"'"'s outboard shoulder when the at least one occupant is sitting in the at least one seat and the door is closed.

20. The door of claim 18, wherein the hinge has an axis that slopes rearwardly such that the door is held open by gravity.
