## Abstract

An adjustable pedal assembly for an exercise machine, such as an elliptical trainer, may include a link and a pedal pivotally connected to the link The pedal assembly may further include a damping assembly, which may provide dynamic damping to the pedal during use of the exercise machine. The damping assembly may be adjustable such that a user can select the level of damping. The damping assembly may include at least one resilient member configured to engage the pedal for damping pivotal movement of the pedal, and an actuator operable to selected a level of damping provided to the pedal by the at least one resilient member.

## Claims

### Claim 1

A pedal assembly for an exercise machine, the pedal assembly comprising:
a foot link;
a foot member pivotally connected to the foot link;
a support member positioned between the foot member and the foot link;
a selector mechanism movable with respect to the foot member at least between a first position in which the foot member is supported by the support member and a second position in which the foot member is not supported by the support member.

### Claim 2 (depends on 1)

The pedal assembly of claim 1, wherein the selector mechanism comprises a selector platform configured to move in a plane to position the selector platform between the first position and the second position.

### Claim 3 (depends on 2)

The pedal assembly of claim 2, wherein the selector platform is pivotally coupled to the foot member.

### Claim 4 (depends on 2)

The pedal assembly of claim 2, wherein the selector platform comprises a contact side positioned to at least partially contact the foot member during at least a portion of a stroke of the pedal assembly, and an engagement side in contact with the support member when the selector platform is in the first position.

### Claim 5 (depends on 4)

The pedal assembly of claim 4, wherein the engagement side comprises one or more engagement features configured to resist relative movement between the selector platform and the support member.

### Claim 6 (depends on 5)

The pedal assembly of claim 5, comprising a plurality of springs, and wherein the support member is one of the plurality of springs.

### Claim 7 (depends on 6)

The pedal assembly of claim 6, wherein the plurality of springs comprises a first spring and a second spring stiffer than the first spring.

### Claim 8 (depends on 1)

The pedal assembly of claim 1, wherein the support member is formed of resilient material.

### Claim 9 (depends on 6)

The pedal assembly of claim 6, wherein the plurality of springs comprises a first spring and a second spring, and wherein the one or more engagement features comprise a first seat to resist relative movement between the first spring and the selector platform when the selector platform is in the first position.

### Claim 10 (depends on 9)

The pedal assembly of claim 9, wherein the selector platform is configured such that the foot member is not supported by the second spring when the selector platform is in the first position.

### Claim 11 (depends on 9)

The pedal assembly of claim 9, further comprising a second seat configured to resist relative movement between the second spring and the selector platform when the selector mechanism is in a third position.

### Claim 12 (depends on 6)

The pedal assembly of claim 6, wherein the engagement side comprises a first region configured to engage only one spring of the plurality of springs and a second region configured to engage only another one of the plurality of springs.

### Claim 13 (depends on 4)

The pedal assembly of claim 4, wherein the support member is a first resilient member, the pedal assembly further comprising a second resilient member, and wherein the engagement side comprises a first engagement sector including engagement features to resist relative movement between the selector platform and the first resilient member, the second resilient member, or both.
