## Abstract

A mechanical adaptation to a vehicle power window controls is provided that require less hand/finger coordination and less force to actuate, therefore becoming useful for persons with limited control of their hands (e.g., arthritis, muscular dystrophy, multiple sclerosis, cerebral palsy, and spinal cord injury, among others). A power window control includes four levers, one on each control switch. Two of the levers are long and the other two are shorter. The long levers are provided on the two switches further away from the user (which control the front and rear left side windows). The short levers are attached to the two switches closer to the user (which control the front and rear right side windows). The base of each lever can be attached to the corresponding switch through a heavy-duty double-sided tape, where for flat switches, the lever is attached directly to the switch surface and for contoured switches, an adapter can be provided between the base of the lever and the surface of the power window switch.

## Claims

### Claim 1

A switch lever system for a vehicle power window switch assembly, said switch lever system comprising:
a first lever element having a first vertical tab configured to control a driver's side window of a vehicle; and
a second lever element having a second vertical tab configured to control a passenger's side window of a vehicle, wherein said first lever element and said second lever element are positioned side-by-side on a power window switch assembly of said vehicle and a height of said first vertical tab is greater than a height of said second vertical tab and the first lever element and the second lever element comprise a base having a clamp element configured to secure said first and second lever elements against window switch caps of a vehicle power window switch assembly.

### Claim 2 (depends on 1)

The switch lever system of claim 1, wherein said clamp elements comprise an end adapted to engage at least one of a front end of said window switch cap or a rear end of said window switch cap.

### Claim 3

A vehicle power window switch assembly comprising:
a first window switch including a first lever element with a first vertical tab configured to control a driver's side window of a vehicle; and
a second window switch including a second lever element with a second vertical tab configured to control a passenger's side window of a vehicle and having a height smaller than a height of said first vertical tab, wherein said first window switch and said second window switch are provided side-by-side on a power window switch assembly so that said first window switch is positioned on a side of said second window switch closer to a vehicle door panel, and said first lever element and said second lever element comprise a base having a clamp element configured to secure said first and second lever elements against window switch caps of said vehicle power window switch assembly.

### Claim 4 (depends on 3)

The vehicle power window switch assembly of claim 3, wherein said clamp elements comprise an end adapted to engage at least one of a front end of said window switch cap or a rear end of said window switch cap.

### Claim 5

A retrofit kit for adapting a vehicle power window switch assembly, said kit comprising:
a pair of first lever elements, each having a first horizontal base and a first vertical tab longitudinally extending perpendicular to said first horizontal base; and
a pair of second lever elements, each having a second horizontal base and a second vertical tab longitudinally extending perpendicular to said first horizontal base, wherein a height of said first vertical tab is greater than a height of said second vertical tab, said pair of first lever elements and said pair of second lever elements comprise a clamp element configured to secure said pair of first lever elements and said pair of second lever elements against window switch caps of a vehicle power window switch assembly.
