Seat belt attachment clamp and method

1. An attachment clamp for attaching a seat belt to a seat frame of a bus seat, the attachment clamp comprising:

at least one upper arm having at least one slot disposed through the at least one upper arm;

at least one lower arm that is received within the at least one slot of the at least one upper arm, the lower arm having a seat belt retainer opening configured to receive the seat belt; and

a receiving channel defined by the at least one upper arm and the at least one lower arm, the receiving channel configured to receive the seat frame, wherein the upper arm and the lower arm are pivotable with respect to each other and wherein the upper arm and the lower arm are fastenable to each other, wherein the at least one lower arm has a first flange and the at least one upper arm has a second flange, wherein the first flange is fastened to the second flange with a fastener, the at least one lower arm includes a first clamp portion defining a part of the receiving channel, and the at least one upper arm includes a second clamp portion defining a part of the receiving channel, and the first clamp portion includes a first leg extending generally perpendicularly from the first flange, a second leg extending generally perpendicularly from the first leg, and a third leg extending generally perpendicularly from the second leg.

2. The attachment clamp of claim 1 further comprising a shoulder portion extending from the third leg of the first clamp portion, wherein the shoulder portion has a width that is wider than the width of the first clamp portion.

3. The attachment clamp of claim 2 wherein the shoulder portion includes the seat belt retainer opening for receiving the seat belt.

4. The attachment clamp of claim 1 wherein the second clamp portion includes a fourth leg extending generally perpendicularly from the second flange, and a fifth leg extending generally perpendicularly from the fourth leg.

5. The attachment clamp of claim 4 further comprising a body portion extending from the fifth leg of the second clamp portion, wherein the at least one slot is disposed through the body portion.

6. The attachment clamp of claim 1 wherein the at least one slot has a width that is smaller than the width of the shoulder portion.

7. The attachment clamp of claim 1 , wherein the at least one slot has a depth that is larger than the depth of the at least one lower arm at the shoulder portion.

8. An attachment clamp for attaching a seat belt to a rear crossmember of a seat frame of a bus seat, the attachment clamp comprising:

at least one lower arm having a first flange, a first clamp portion extending from the first flange, and a shoulder portion extending from the first clamp portion, wherein the shoulder portion has a first width;

at least one upper arm having a second flange, a second clamp portion extending from the second flange, and a body portion extending from the second clamp portion, wherein the at least one lower arm is received within at least one slot of the at least one upper arm, wherein the at least one slot has a second width smaller than the first width; and

a receiving channel defined by the at least one upper arm and the at least one lower arm, the receiving channel being configured to receive the rear crossmember of the seat frame, wherein the upper arm and the lower arm are pivotable with respect to each other, wherein the at least one lower arm comprises two lower arms received in one upper arm.

9. The attachment clamp of claim 8 wherein the first flange is fastened to the second flange with a fastener.

10. The attachment clamp of claim 8 wherein the receiving channel is generally rectangular in cross-section.

11. The attachment clamp of claim 8 wherein the at least one slot has a depth that is larger than a depth of the shoulder portion.
