Abstract

Disclosed seat belt assemblies or mechanisms include a seat belt guide which positions the seat belt for convenient ingress and egress by an operator, but in a position which reminds the operator to fasten the seat belt. The seat belt guide is configured to be stiffer in one direction of movement to maintain the metal tab of the seat belt at a raised position to one side of the operator seat, for example at a position adjacent to an operator joystick or control, but to allow the guide and the seat belt to be moved across the operator seat (and operator) for buckling.

First claim

What is claimed is:

1. A seat belt guide for a seat belt, having a retractor, on a power machine having one of a joystick and a control lever manipulable by an operator, the seat belt guide comprising:
a stiffener;
an attachment portion connected to a first end of the stiffener and configured to be attached to the retractor so that the stiffener extends from the retractor and an operator seat;
a tongue engagement member connected to a second end of the stiffener and configured to support a tongue of a seat belt when the seat belt is retracted by the retractor, wherein the retractor applies a force against the tongue to hold the tongue against the tongue engagement member; and
wherein the stiffener and tongue engagement member are configured and arranged to hold the tongue in a generally inline position with respect to a longitudinal direction of the stiffener and at a raised position relative to the operator seat when the tongue is not engaged with a corresponding seat belt buckle such that the tongue interferes with operation of the joystick or control lever.

2. The seat belt guide of claim 1 , wherein the stiffening element is configured to allow bending in the longitudinal direction, but resist bending in directions orthogonal to the longitudinal direction.

3. The seat belt guide of claim 1 , wherein the tongue engagement member includes a tab configured to support the tongue in the generally inline position with respect to a longitudinal direction of the stiffener.

4. The seat belt guide of claim 3 , wherein the tab of the tongue engagement member extends in the longitudinal direction from an end surface of the tongue engagement member.

5. The seat belt guide of claim 1 , wherein the tongue engagement member and the attachment portion each include apertures, and wherein the seat belt guide further comprises a material on each of two sides of the stiffening element, the material extending through the apertures of the tongue engagement member and the attachment portion.

6. The seat belt guide of claim 2 , wherein the stiffening element comprises spring steel.

7. The seat belt guide of claim 2 , wherein the stiffening element comprises a plastic or metal.

8. An operator compartment of a power machine, the operator compartment comprising:
an operator seat;
an operator input device positioned proximal to the operator seat;
a seat belt including a first portion having a tongue and a second portion having a buckle configured to engage with the tongue; and
a seat belt guide configured to position the seat belt tongue at a position raised from the operator seat and adjacent to the operator input device so as to allow ingress into the operator compartment to access the operator seat without interference from the first portion of the seat belt when the tongue is not engaged with the buckle so as to interfere with operation of the operator input device.

9. The operator compartment of claim 8 , wherein the operator input device is a joystick controller positioned in front of the operator seat.

10. The operator compartment of claim 8 , wherein the seat belt guide further comprises a stiffener configured to allow bending in a longitudinal direction of the seat belt guide, but resist bending in directions orthogonal to the longitudinal direction.

11. The operator compartment of claim 10 , wherein the seat belt guide further comprises a tongue engagement member connected to the stiffener and configured to support the tongue at the position raised from the operator seat.

12. The operator compartment of claim 11 , wherein the tongue engagement member includes a tab configured to support the tongue in a generally inline position with respect to the longitudinal direction of the seat belt guide.

13. The operator compartment of claim 12 , wherein the tab of the tongue engagement member extends in the longitudinal direction from an end surface of the tongue engagement member.

14. The operator compartment of claim 11 , wherein the seat belt guide further comprises an attachment portion connected to the stiffener and attached to a portion of the operator compartment.

15. The seat belt guide of claim 14 , wherein the tongue engagement member and the attachment portion each include apertures, and wherein the seat belt guide further comprises a material on each of two sides of a stiffening element of the stiffener, the material extending through the apertures of the tongue engagement member and the attachment portion.

16. The operator compartment of claim 10 , wherein the stiffener includes a stiffening element configured to allow bending in the longitudinal direction, but resist bending in directions orthogonal to the longitudinal direction.

17. The operator compartment of claim 15 , wherein the stiffening element comprises at least one of spring steel, metal, and plastic.
