## Abstract

A vehicle floor silencer includes a base portion and a flange formed along an edge of the base portion. The flange includes a step, a wall extending from the step, and at least one wall support element extending from the wall to the step and structured to prevent at least an associated portion of the wall from deflecting in a direction toward an end of the step. The wall support is structured to prevent deflection of the wall along an edge of the floor silencer.

## Claims

### Claim 1

A vehicle floor silencer comprising:
a base portion; and
a flange formed along an edge of the base portion, the flange including a step, a wall extending from the step, and at least one wall support element extending from the wall to the step and structured to prevent at least an associated portion of the wall from deflecting in a direction toward an end of the step.

### Claim 2 (depends on 1)

The vehicle floor silencer of claim 1 wherein the step has an upper surface, the wall has an outer surface, and wherein the at least one wall support element extends between the wall outer surface and the step upper surface.

### Claim 3 (depends on 2)

The vehicle floor silencer of claim 2 wherein the step has a lower surface extending opposite the step upper surface, and wherein the step lower surface and the base portion combine to define a cavity therebetween.

### Claim 4 (depends on 2)

The vehicle floor silencer of claim 2 wherein the base portion has a lower surface defining a plane, and the step has a lower surface extending opposite the step upper surface and defining another plane extending parallel or substantially parallel the plane and spaced apart from the plane.

### Claim 5 (depends on 2)

The vehicle floor silencer of claim 2 wherein the wall outer surface is structured to extend generally vertically from the step upper surface when the floor silencer is mounted to a floor of a vehicle, and wherein the wall has an uppermost edge and an inner surface extending from the uppermost edge to an upper surface of the base portion.

### Claim 6 (depends on 5)

The vehicle floor silencer of claim 5 wherein the wall tapers from a relatively smaller cross sectional area proximate the wall uppermost edge to a relatively larger cross sectional area in a direction toward the base portion upper surface.

### Claim 7 (depends on 1)

The vehicle floor silencer of claim 1 wherein the at least one wall support element is spaced apart from the end of the step.

### Claim 8 (depends on 1)

The vehicle floor silencer of claim 1 comprising a plurality of wall support elements extending from the wall to the step, each wall support element being structured to prevent an associated portion of the wall from deflecting in a direction toward the end of the step.

### Claim 9 (depends on 1)

The vehicle floor silencer of claim 1 wherein the at least one wall support element has a uniform thickness.

### Claim 10 (depends on 9)

The vehicle floor silencer of claim 9 wherein the at least one wall support element has a thickness substantially equal to a thickness of the step.

### Claim 11 (depends on 1)

The vehicle floor silencer of claim 1 wherein the floor silencer is formed from a moldable felt material having tensile strength in the range 29-39 kPa.
