## Abstract

A battery-powered motorized window treatment for covering at least a portion of a window may be adjusted into a service position to allow for access to at least one battery that is powering the motorized window treatment. A headrail of the motorized window treatment may be adjusted to the service position to allow for easy replacement of the batteries without unmounting the headrail and without requiring tools. The motorized window treatment may comprise brackets having buttons that may be actuated to release the headrail from a locked position, such that the head rail may be rotated into the service position. The headrail easily rotates through a controlled movement into the service position, such that a user only needs one free hand available to move the motorized window treatment into the service position and change the batteries.

### Claim 6 (depends on 2)

The motorized window treatment of claim 2, wherein the axle is located below the enclosure, such that the center of gravity of the motorized window treatment causes the enclosure to rotate away from the window on its own.

### Claim 7 (depends on 6)

The motorized window treatment of claim 6, wherein the mounting bracket further comprises a spring for biasing the rotating portion towards the mounting portion, such that the enclosure rotates in a controlled movement when the motorized window treatment is released from the locked position.

### Claim 8 (depends on 1)

The motorized window treatment of claim 1, further comprising:
first and second roller tube end brackets coupled to the enclosure; and
a roller tube rotatably coupled between the first and second roller tube brackets and adapted to windingly receive the covering material;
wherein the roller tube is spaced apart from the enclosure.

### Claim 9 (depends on 8)

The motorized window treatment of claim 8, wherein a rear side of the enclosure is open and is adapted to be rotated away from the window in the service position to allow for access to the at least one battery.

### Claim 10 (depends on 8)

The motorized window treatment of claim 8, wherein a top side of the enclosure is open and is adapted to be rotated away from the window in the service position to allow for access to the at least one battery.

### Claim 11 (depends on 8)

The motorized window treatment of claim 8, wherein the motor drive unit is located inside the roller tube and is electrically coupled to the battery in the enclosure.

### Claim 12 (depends on 1)

The motorized window treatment of claim 1, wherein the enclosure comprises a headrail in which the motor drive unit is located, the covering material extending from the headrail towards the bottom of the window.

### Claim 13 (depends on 12)

The motorized window treatment of claim 12, further comprising:
a drive shaft located in the headrail and coupled to the motor drive unit; and
at least one lift cord rotatably received around the drive shaft and extending to a bottom of the covering material for raising and lowering the covering material between a fully-open and fully-closed position.

### Claim 13 (depends on 13)

The motorized window treatment of claim 13, wherein the headrail is adapted to be displaced away from the window and then to be rotated away from the window.

### Claim 14 (depends on 13)

The motorized window treatment of claim 13, wherein a top side of the headrail is adapted to be rotated away from the window in the service position.

### Claim 15 (depends on 1)

The motorized window treatment of claim 1, wherein the enclosure extends for approximately the width of the covering material.

### Claim 16

A mounting bracket for a motorized window treatment adapted to be mounted to a surface, the motorized window treatment comprising an enclosure for holding at least one battery and a covering material adapted to hang from a position adjacent the enclosure to cover at least a portion of a window, the mounting bracket comprising:
a mounting portion adapted to be fastened to the surface;
a rotating portion coupled to a top side of the enclosure, the rotating portion comprising a clip adapted to be coupled to a bottom side of the enclosure; and
an axle for rotatably coupling the rotating portion to the mounting portion, such that the rotating portion pivots about the axle with respect to the mounting portion;
wherein the axle is located below the clip of the rotating portion, such that the center of gravity of the motorized window treatment is adapted to cause the enclosure to rotate away from the window on its own.

### Claim 17 (depends on 16)

The mounting bracket of claim 16, further comprising:
a spring for biasing the rotating portion towards the mounting portion, such that the enclosure rotates in a controlled movement when the rotating portion is released from the locked position.
