MOTORIZED WINDOW TREATMENT

1 . A mounting bracket configured to mount a motorized window treatment to a structure surrounding a window by rotatably supporting an end of a roller tube of the motorized window treatment, the mounting bracket comprising:

a stationary portion configured to be attached to the structure surrounding the window, the stationary portion comprising a catch; and

a pivoting portion configured to receive an end portion of a housing of a motor drive unit located within the roller tube, the pivoting portion configured to operate the motorized window treatment between an operating position and an extended position, wherein the end portion of the housing is accessible when the motorized window treatment is in the extended position, and wherein the pivoting portion is aligned with the stationary portion when the motorized window treatment is in the operating position such that the end portion of the housing is covered by the stationary portion, the pivoting portion comprising a stopping mechanism configured to engage the catch to prevent the motorized window treatment from extending beyond the extended position.

2 . The mounting bracket of claim 1 , wherein the stopping mechanism comprises a flexible strap defining a first strap end and a second strap end, the first strap end configured to be captively received within the pivoting portion of the mounting bracket, the second strap end configured to be secured to the stationary portion of the mounting bracket, wherein the flexible strap is configured to prevent the motorized window treatment from pivoting beyond the extended position.

3 . The mounting bracket of claim 2 , wherein the catch extends from an upper wall of the stationary portion.

4 . The mounting bracket of claim 1 , wherein the stopping mechanism comprises a stopping arm extending from a lower wall of the pivoting portion.

5 . The mounting bracket of claim 4 , wherein the catch extends from a lower wall of the stationary portion.

6 . The mounting bracket of claim 4 , wherein the stopping arm defines an upper surface that is configured to abut the catch.

7 . The mounting bracket of claim 4 , wherein the stopping arm is configured to engage the stationary portion to secure the motorized window treatment in the operating position.

8 . The mounting bracket of claim 4 , wherein the pivoting portion defines one or more slide guides.

9 . The mounting bracket of claim 8 , wherein the stationary portion defines channels that are configured to receive the slide guides as the motorized window treatment is operated between the operating position and the extended position.

10 . The mounting bracket of claim 9 , wherein a curvature of the channels defines a pivot path of the pivoting portion of the mounting bracket as the motorized window treatment is operated between the operating position and the extended position.

11 . The mounting bracket of claim 1 , wherein the pivoting portion defines an opening configured to receive the end portion of the housing, wherein the pivoting portion is configured to attach the end portion of the housing to the mounting bracket.

12 . The mounting bracket of claim 11 , wherein an inner surface of the pivoting portion that defines the opening comprises a plurality of tabs configured to engage complementary features on the end portion of the housing to attach the end portion of the housing to the mounting bracket.

13 . The mounting bracket of claim 2 , wherein the pivoting portion of the mounting bracket defines a first channel that is configured to receive the first strap end, and wherein first strap end is configured to translate within the first channel as the motorized window treatment is operated between the operating position and the extended position.

14 . The mounting bracket of claim 13 , wherein the stationary portion of the mounting bracket comprises a first arm, a second arm that is substantially perpendicular to the first arm, and a plate that is attached to the first arm and the second arm.

15 . The mounting bracket of claim 14 , wherein, when the motorized window treatment is in the extended position, the first strap end interlocks with a tab within the first channel of the pivoting portion of the mounting bracket and the second strap end interlocks with a catch on the stationary portion of the mounting bracket.

16 . The mounting bracket of claim 15 , wherein the catch extends from the first arm of the stationary portion of the mounting bracket.

17 . The mounting bracket of claim 15 , wherein the pivoting portion of the mounting bracket comprises a latch that is configured to secure the motorized window treatment in the operating position.

18 . The mounting bracket of claim 17 , wherein when the motorized window treatment is in the operating position, the latch engages a tab extending from the first arm of the stationary portion of the mounting bracket.

19 . The mounting bracket of claim 18 , wherein the latch is configured to disengage from the tab when a force greater than a pre-defined threshold force is applied to the roller tube in a direction away from the window.

20 . The mounting bracket of claim 14 , wherein the plate defines a slide extending from an inner surface of the stationary portion of the mounting bracket.

21 . The mounting bracket of claim 20 , wherein a curvature of the slide defines a pivot path of the pivoting portion of the mounting bracket as the motorized window treatment is operated between the operating position and the extended position.

22 . The mounting bracket of claim 20 , wherein the pivoting portion comprises a second channel that is configured to receive the slide.

23 . The mounting bracket of claim 21 , wherein the pivoting portion defines a finger that extends proximate to the second channel, the finger configured to guide the slide into the second channel.

24 . The mounting bracket of claim 21 , wherein the pivot path defines a fulcrum located below a bottom edge of the stationary portion.

25 . The mounting bracket of claim 2 , wherein the flexible strap comprises metal, plastic, or a composite material.
