Abstract

A bicycle seat apparatus including at least one rail and a saddle shell. The at least one rail can include a first mounting portion. The first mounting portion can include an ankle. A cross section of a terminus of the ankle can be larger than a cross section of the at least one rail. The saddle shell can include at least one mounting cup configured to mate with the first mounting portion of the at least one rail. A cross section of a base of the at least one mounting cup can be larger than a cross section of the terminus of the ankle.

First claim

What is claimed is:

1. A bicycle seat apparatus, comprising:
at least one rail including a front mounting portion comprising a front ankle and a rear mounting portion comprising a rear ankle, wherein a cross sectional area of a terminus of the front ankle is larger than a cross sectional area of the at least one rail, and wherein a cross sectional area of a terminus of the rear ankle is larger than the cross sectional area of the at least one rail; and
a saddle shell including a front mounting cup configured to mate with the front mounting portion of the at least one rail and a rear mounting cup configured to mate with the rear mounting portion of the at least one rail, wherein a cross sectional area of a base of the front mounting cup is larger than the cross sectional area of the terminus of the front ankle, and wherein a cross sectional area of a base of the rear mounting cup is larger than the cross sectional area of the terminus of the rear ankle.

2. The apparatus of claim 1 , wherein the front mounting portion intersects the saddle shell at an angle greater than 15 degrees.

3. The apparatus of claim 1 , wherein the front mounting portion intersects the saddle shell at an angle greater than 20 degrees.

4. The apparatus of claim 1 , wherein the front mounting portion intersects the saddle shell at an angle in a range from about 15 degrees to about 45 degrees.

5. The apparatus of claim 1 , wherein the front mounting portion intersects the saddle shell at an angle in a range from about 15 degrees to about 55 degrees.

6. The apparatus of claim 1 , wherein the front mounting portion is bonded to the front mounting cup.

7. The apparatus of claim 1 , wherein the front mounting portion includes a tab and the front mounting cup includes a notch configured to mate with the tab.

8. The apparatus of claim 1 , wherein the front mounting cup includes an indexing feature configured to mate with the front mounting portion to prevent rotation of the front mounting portion.

9. The apparatus of claim 1 , wherein the front ankle has a cone shape.

10. The apparatus of claim 1 , wherein the front ankle comprises a first front ankle, wherein the front mounting portion also includes a second front ankle, and wherein a cross sectional area of a terminus of the second front ankle is larger than the cross sectional area of the at least one rail.

11. The apparatus of claim 10 , wherein the front mounting portion further comprises a cleat that is mounted to the first front ankle and the second front ankle, and wherein the front mounting cup is configured to receive the cleat.

12. The apparatus of claim 11 , wherein the front mounting cup includes a base plate and a tongue, and wherein the cleat is bonded in between the base plate and the tongue.

13. The apparatus of claim 1 , wherein the rear mounting portion further comprises a tab, and wherein the rear mounting cup includes a hole configured to receive the tab.

14. The apparatus of claim 13 , wherein the rear mounting portion further comprises a notch, and wherein the rear mounting cup includes an alignment ridge configured to mate with the notch.

15. The apparatus of claim 1 , wherein the rear mounting portion further comprises a flange mounted to the terminus of the rear ankle, and wherein the rear mounting cup includes a bonding surface configured to mate with the flange.

16. The apparatus of claim 1 , wherein the rear mounting cup further comprises a diffusion base configured to support the rear ankle.
